Figure 3 is a block diagram showing a configuration for controlling an appliance in the diagnostic system for household appliances according to Figure 1.

Household appliance 101, is designed as described above has the configuration of a control to perform the mode of washing, rinsing, drying, pressing, etc. for washing Laundry in the home is the first device 101, data generated during the work of the household appliance 101, and when the predictive diagnostic set based on the input selection module, the formation of technical information, including data appliance 101, in the form of a digital signal of a predetermined format and output a predetermined sound signal based on the digital signal.

Referring to Figure 3, household appliance 101 includes a device 125 input receiving unit 170, a memory 145, the device 146 storing data driver 180, the modulator 150, the device 160 audio output, and a controller 140 for controlling the entire operation of household appliance 101.

The device 125 input contains at least one input module for inputting a predetermined signal or data consumer device 101 according to the processing of the user. The device 125 input includes the pointing device 117 and the module 130 of the selection.

The module 130 has at least one input module. After selecting a predictive diagnostic module 130 of choice applies an output command signal to the controller 140, so that the technical information is displayed in the form of a pre-defined audio signal through the device 160 audio output.

The module 130 may include an input module that is separate from the input modules of the manipulator 117. lternative, the pointing device 117 may include two or more input modules, which can work or be recognized as a module of choice for simultaneous administration, or a specific input module, which can work or be recognized as a module, choose from when running sequentially or within a predetermined time or more.

When moving in predictive diagnostics, the module 130 selection enables/disables device 160 audio output. That is, when the output command signal is entered via the module 130 of choice, the digital signal that includes technical information, displayed in the form of a predetermined audio signal in response to a control command from the controller 140. At this time, the device 160 audio output works to output a beep.

The pointing device 117 receives data, such as the mode or function setting, according to the operation of the household appliance 101 and applies the received data to the controller 140. The pointing device 117 also makes settings related to output the sound signals. I.e. the pointing device 117 receives the values to set the output audio signal level of the sound signal that should be output, etc.

The device 125 entry, which includes the module 130 of choice and the pointing device 117 can be made is with the ability to include buttons, dome switch, a touch pad (static pressure/capacitance), a rotary wheel, a rotary switch, mouse, rotary switch, rotary disk, etc. Any device can act as a device 125 to enter until it forms a pre-defined input data by means such as pressing, rotating, pressing or contact.

The receiving device 170 includes at least one sensor for reading temperature, pressure, voltage, current, water level, number of rotations, etc. and applies the read or measured data to the controller 140. For example, when water is supplied or discharged into or from the washing machine, the receiving device 170 can measure the water level, the temperature of the water and the speed of rotation of the tank or drum. The receiving device 170 includes at least one sensor temperature measurement (not shown).

The driver 180 controls the actuation appliance 101 in response to a control command from the controller 140 so that the appliance 101 performs a specified operation. Therefore, a device for washing Laundry by executing a sequence of modes, including the mode of washing, rinsing and drying cycle. The driver 180 includes the impact of the motor controller (not shown) to apply a functional control signal to the electric motor.

For example, in the case of the washing machine, the driver 180 can operate the motor, which rotates the tank or drum, and to control operation of the electric motor, to wash dirty linen to the Laundry by rotating the tank or drum. In addition, the driver 180 can control the valve in response to a control command from the controller 140, to submit or to drain the water.

The memory 145 stores control data for control of household appliance 101, the reference data used during the operation, control of household appliance, etc.

Memory 145 includes all of the storage modules, which includes permanent memory (ROM) or electrically erasable programmable ROM (EEPROM) for storing control data for household appliance. The device 146 data storage is a buffer controller 140, which stores the data temporarily. The device 146 data storage may be, for example, dynamic random access memory device (DRAM) or static RAM (SRAM). If necessary, the device 146 data storage may be included in the controller 140 or the memory 145.

Although household appliance 101 performs the requested operation, the memory 145 stores the information about the job, including data operating mode generated in the course of the work, and set the data entered by manipulate is and 117, so household appliance 101 performs the desired operation, information use, including the number of cases of performing a specific operation of the household device 101, and information of the household appliance 101, and information about faults, which includes information about the cause or location of a fault when the household appliance 101 is malfunctioning.

The controller 140 when the signal to move in predictive diagnostics is entered from the module 130 selection, samples of technical information, stored in the memory 145 or device 146 storage, generates a digital signal of a predetermined format of technical information and applies the digital signal to the modulator 150. In addition, when the module 130 selection is controlled by the controller 140 controls the device 160 audio output to work with him.

The controller 140 includes a main controller 141 to control the flow of data input or output to or from a household appliance 101, the development and application of control commands based on input from the recipient device 170, or providing read data driver 180 to control the driver 180 to work with an appliance 101, and the encoder 142 to convert technical information into a digital signal of a predetermined format in the TVET on the input module 130 of choice so what sound signal on the basis of the digital signal is output.

The main controller 141, the transition in predictive diagnostics in response to the input module 130 selection, displays the initial sound indicating the start of predictive diagnostics, through the device 160 audio output and display predefined information indicating execution of predictive diagnostics via the display device 118.

In addition, when the digital signal generated by the encoder 142 is applied to the modulator 150, and the audio signal thus output from the device 160 audio output, the main controller 141 controls the device 160 audio output, to output a predetermined warning sound before and after output the sound signal. Alert sound before the sound is output may be omitted if necessary.

On the other hand, if the device 160 audio output includes two or more audio output, the main controller 141 may control the audio output, to output a notification sound and a sound signal that includes technical information through various devices audio output, respectively.

After entering the predictive diagnostics the main controller 141 deactivates m is nipulator 117 except the power key and power module 130 choice and manages the receptive device 170 and the driver 180, to instruct appliance 101 to interrupt all other operations.

In addition, when any control button of the pointing device 117 to configure household appliance 101 is pressed after power-up, the main controller 141 starts predictive diagnostics, even if the module 130 of choice is introduced. In particular, if the module 130 of choice is not available separately, and pressing a combination of two or more of the many control keys pointing device 117 is recognized as the input module 130 of choice, the main controller 141 starts predictive diagnostics only when the module 130 of choice is pressed by the specified key combinations without other pressing after pressing power.

I.e. it is believed that the operation of the household appliance by means of the manipulator 117 indicates that the user has no intention to move in predictive diagnostics, and the main controller 141 thus does not go into predictive diagnostics. In addition, it is possible to prevent an optional mode intelligent diagnostic due to failure in the management of the manipulator 117.

The encoder 142 samples the technical information stored in the memory 145, encodes technical information according to pre-determined is by the encoding scheme and adds a preamble and bit error checking result data signal, in order to generate a digital signal of a predetermined format. The encoder 142 generates a digital signal consisting of a set of symbols by coding technical information.

The encoder 142 encodes technical information using a coding scheme with correction of bit errors to protect against data loss that may occur during the transfer of technical information as a sound signal over a communication network. The encoder 142 uses a direct error correction (FEC) as an example of the coding scheme with correction of bit errors. The encoder 142 encodes technical information using convolutional coding. Thus, the diagnostic server of the service center 200 decodes the sound using the algorithm of Viterbi decoding as convolutional encoding.

The encoder 142 performs an encoding-based scheme with code rate 1/2, in which 2 bits are output for input 1-bit, or on the basis of the scheme with code rate 2/3. In addition, the encoder 142 reduces the number of redundant bits using a thinning algorithm.

The encoder 142 also performs a bitwise interleaving against packet errors that may occur during data transmission. The encoder 142 performs a bitwise interleaving for the data based on a predefined number of bits (for example, 32 bits. That is, when data is 60 bytes, the encoder 142 performs a bitwise interleaving for the data rearranging the data based on the four-on-four bytes according to a predefined rule.

During the formation of the digital signal encoder 142 may divide the digital signal into multiple frames by a predetermined size and package frames in the package. In addition, the encoder 142 may set the interframe spacing (IFS) a pre-defined duration between adjacent frames of the digital signal. In addition, during the conversion of the signals of the encoder can set the delay time symbol in the period in which the data value is changed to exclude the reverb, which affects the following conversion of the signals due to the principle of charging and discharging of the capacitor.

Provided that the length of each of the symbols constituting the digital signal has a duration of a symbol, and the fundamental length frequency signal comprising the audio signal from the device 160 audio output corresponding to each symbol has a duration of a symbol, the encoder 142 may set the delay time within the duration of a symbol relative to a single character. In this case, the length of the time lag varies depending on the length of the duration of the end-of-the A.

Technical information includes information about the work includes the functional settings, data, operating mode, etc., information use and information about faults relative failure, as described above. Technical information is data consisting of a combination of zeros or units, which are the digital signal format that is recognizable by the controller 140.

The controller 140 generates a digital signal of a predetermined format through data classification technical information, including specific data classified data and dividing the result data for a certain size or a combination of the result data, and applies the generated digital signal to the modulator 150.

In addition, the controller 140 may change the number of symbols corresponding to the signals output frequency according to the number of frequencies used in the modulator 150.

The modulator 150 applies a signal to actuate the device 160 audio output in response to the digital signal from the controller 140, so that the device 160 audio output outputs the audio signal. The audio output signal thus includes technical information.

The modulator 150 applies a signal to actuate the device 160 audio output, so that the decree is hydrated frequency signal, corresponding to one of the characters that make up the digital signal, is displayed during the time of the symbol.

The modulator 150 performs control so that the audio signal is output through multiple frequency bands in accordance with the digital signal when the number of symbols for each frequency, based on the number of frequencies used in accordance with the setting of the controller 140. For example, one frequency signal can be displayed per 1 symbol, when two frequencies are used, and a single frequency signal may be output based on 2 characters, when four frequencies are used.

The modulator 150 includes a frequency oscillators (not shown) for the formation of many frequencies, much of the available frequencies, and controls the device 160 audio output so that it displays the frequency signals from the frequency of the oscillators, which are specified in accordance with the digital signal.

The modulator 150 converts the digital signal from the controller 140 in the audio signal using the frequency-shift keying, amplitude manipulation or phase manipulation in the management device 160 audio output to output an audio signal in accordance with a digital signal.

Frequency shift keying converts the digital signal into a signal having a frequency corresponding to C is aceniu digital data signal, amplitude shift keying converts the digital signal by changing the amplitude of the digital signal according to the value data, and phase shift keying converts the digital signal by changing the phase of the digital signal according to the value data.

Binary frequency shift keying (BFSK), which is a type of frequency-shift keying, converts the digital signal into a signal of a first frequency when the digital signal has a data value of 0, and a signal of a second frequency when it has a value data of 1. For example, BFSK converts the data value of 0 in the signal frequency of 2.6 kHz and converts the data value 1 into a signal of a frequency of 2.8 kHz.

Amplitude shift keying can convert the digital signal into a signal of a frequency of 2.6 kHz with an amplitude of 1, when the digital signal has a data value of 0, and with an amplitude of 2, when it has a value data of 1.

Although the modulator 150 is described using frequency-shift keying as an example, the modulation scheme can be changed. In addition, the used bandwidth is a simple example and can be changed.

If the delay time is set in the digital signal, the modulator 150 interrupts the modulation during the interval in which the delay time is set in the digital signal. The modulator 150 modulates a digital signal using a pulse-width modulating the tion (PWM) and switches the oscillation frequency to deactivate modulation during the interval, in which the delay time is set to temporarily interrupt the modulation frequency signals during the time lag. He manages the intersymbol reverberation sound signal output from the device 160 audio output.

The device 160 audio output is activated or deactivated according to the control command from the controller 140.

Technical information for household appliance, which is transmitted after conversion to audio signals for fault diagnosis involves a lot of data associated with operations of the household appliance. Household appliance stores many diagnostic data required for fault diagnosis. The following information describes the technical information.

As described above, household appliance stores technical information in the memory 145, and technical information includes many diagnostic data.

The main controller 141 stores the diagnostic data corresponding to the operating mode of the domestic appliance, in the memory 145 or stores diagnostic data in the memory 145 after temporarily storing the device 146 data storage. Here, the main controller 141 changes the time or frequency save diagnostic data according to the type of diagnostic data.

The main controller 141 reads the diagnostic data stored thus, in the transition to predictive diagnostics, encodes the read diagnostic data into a digital signal in a predefined format through the encoder 142, converts the digital signal into a sound signal through the modulator 150, and outputs the audio signal through the device 160 audio output.

The main controller 141, issue the play initialization data before how to get started, and stores diagnostic data with intervals of a specific period or, if necessary, while the main controller 141 operates according to the setting. Here, the main controller 141 supports the initial value of the operation, which is not actually performed, although it is set to activate.

Depending on the type of diagnostic data, the main controller 141 immediately stores the diagnostic data each time the data value of the diagnostic data is changed, stores the diagnostic data when an error occurs, or stores diagnostic data associated with each operation, such as washing, rinsing or drying, pressing, during shutdown.

Thus, the memory 145 stores technical information, including information about the work, information use and information on faults, under control of the main controller 141. The device 146 data storage also stores temporary data regarding the status and Troubleshooting information generated during the work of the household appliance. For example, technical information may include the number of washing machines, preset mode, information, options, error code, a value measured by a sensor, the data calculated by means of the pin is of Oller 140, and the information about the operation of each component.

"Error code indicates the error code, about which the user is warned when determining abnormality in the washing machine 101 during operation. Ie "error Code indicates a typical error when using the washing machine 101, on which the user is warned when the abnormality occurs in the washing machine 101. "Error code" is set so that it has a length of 1 byte.

For example, "error Code indicates the error message shown on the display (not shown), or a sound signal emitted through the buzzer, when the failure of the washing machine 101 is or usage error occurs. For technical information, this error code is set so that it tells the user the location of the error in the washing machine 101, which fails. The error code can not only be displayed on the display device, but can also be printed on ka is este sound alarm.

For example, when the error code is included in the technical information has a data value of 0, the error code indicates that the washing machine 101 operates normally, or indicates that a violation of work that is not classified as a code error occurs in the washing machine 101. Error code having a data value "1"may indicate a malfunction in the door, "2" - the problem with the water supply, "3" - problem handling "4" imbalance, "5" - the disruption of FE, "6" - a violation of the sensor switch (PE), and "7" is the problem with the water supply (IE), "8" is the disruption of the electric motor (LE), "9" is the disruption of CE and "10" is a problem when drying. Error codes with other data values may indicate other specific violations.

This error code is used to retrieve the associated data according to the error code value, when the diagnostic server was diagnosed with washing machine 101 with failure to compare the extracted data with corresponding reference data or diagnostic data to analyze the cause and remove the measure that should be taken to correct the problem. The diagnostic server determines the operation of the washing machine 101, during which a fault occurs on the basis of the state information including the technical information.

I.e. the user specifies Options for the washing machine 101, for example, the washing time is 15 minutes, drying time wringer is 5 minutes and the washing is 10 minutes as "Options". "Options" is set so that it has a length of 9 bytes. "Options" is stored when the error code occurs, or when the wash cycle is complete.

Dimensions, categories, and titles of technical information are just an example and can be changed depending on characteristics of the household appliance.

The main controller 141 instructs the appliance to operate according to the setting values, for example, the options or the operation mode set through the manipulator device 117 125 input. For example, when the household appliance is a washing machine, the main controller 141 determines the classification of its stage of the work on the preliminary stage, the steps of washing, rinsing, drying, pressing, drying and the stage of completion and additionally classifies each stage in the operation, and stores the information that indicates the operation that the appliance performs for the last time, as state information.

Thus, the status information includes information about an operation that household appliance performs for the last time of all operations household appliance. For example, status information includes information about the phase of work, which household appliance performs for the last time, from the preliminary stage, the steps of washing, rinsing, drying, pressing, drying and completion, at which stages of the washing machine are separated before the washing machine performs the specified operations. Here, each stage can be classified into sub-phases. For example, the step of washing can also be classified into stages indelicate washing, washing by soaking, main wash and wash clean, and the step of rinsing can also be classified on the stages of the first rinse, second rinse third rinse and fourth rinse. The first stage rinse can also be classified on the stage of discharge, the stage is short pressed, the main stage of extraction and the stage of water supply. Status information includes details is rmatio of such accurately classified the operations of the household appliance.

When abnormality occurs during the rinse mode of the washing machine, a value indicating the rinse mode, is stored in the state information, because the mode rinsing performed for the last time. Here, each mode can be further classified, and thus, status information may indicate at what stage of rinsing abnormality occurs in the rinse mode, occurs or not abnormality during spin in the rinse mode, occurs or there is no abnormality in the water, and occurs or not abnormality during unloading.

Here, the status information may have a length of approximately 1 byte and can include information about each of the approximately 60-64 operations, which are separated stages of the household appliance.

Here, the values "0"to"5" state information may indicate the operation of the preliminary stage, in particular, the value "0" may indicate the initialization phase, "2" stage stop "3 - stage scheduling modes, "4", the stage of determining the pause and "5" - the stage of determining the quantity of linen for washing. The value "55" and "56" can specify the stages of drying, in particular, the value "55" may indicate the stage of drying with hot air, and "56" - stage cooling.

The value "6"to"9" can specify the mode indelicate washing, "10" and "11" - soaking, "12"-"20" - dir is m washing, "21"-"48" - rinse, "49"-"52" mode drying wringer, "55" and "56" drying mode, and "57"-"59" - completion mode. When the data value of the state information is "0", it indicates that the power is off, and when the data value is "12", it indicates that the initial water supply performed for the last time in the wash cycle. When the value of the status equals "28", this indicates that the short extraction performed for the last time on the stage of the second rinse.

This status information is updated if necessary during the work of the household appliance. I.e. while the wash cycle is performed, the corresponding status information is stored, and when rinsing is performed after the wash cycle completes, the corresponding value is stored as state information.

The diagnostic server may determine which operation is performed for the last time in household appliance, through the state information included in the technical information, and to perform fault diagnosis using the associated diagnostic data.

General information described above, immediately saved in the device 146 storing data every time when the temporary data is created, or whenever a data value is changed. General data temporarily stored in the device 146 storage given the s and then stored in the memory 145, when an appliance stops working, because all the operations are completed, or because an error occurs.

"Counter operations current limit" specifies the total number of operations current limit up until the appliance does not shut down after starting work. Counter operations current limit is increased by 1 each cycle of switching of the electric motor.

When the motor controller generates and applies a control signal for the electric motor to an electric motor, an excessive current exceeding the allowable level, can be formed, damaging the motor controller and the motor. Thus, the motor controller performs the operation "current limit"to forcibly turn off the current of the motor when the current level reaches a maximum level, which is pre-installed so that it prevents damage to the motor controller and motor due to over-current.

"Counter operations FO", which is the program counter control overcurrent indicates the total number of times when the overcurrent is disabled by hardware up until the appliance does not shut down after starting work. Counter operations restrictions FO specifies the number of times when the overcurrent is limited to p the tool and hardware supported "0", when the motor controller performs control in normal mode. Thus, when the counter value FO is zero, it indicates that the motor controller is functioning normally, and when the counter value FO is not zero, it indicates that an error occurs in the controller of the motor, i.e. the motor controller is faulty.

"Counter definition bubbles" indicates the total number of times the determination of bubbles running up until the appliance does not shut down after starting work.

"Determining the number of rpm" specifies the value of the speed of rotation of the motor, the Hall sensor provided for the motor, measures during operation of the motor. These determine the number of rpm provided the definition of abnormality in the motor or Hall sensor. For example, when the counter operations current limit is not equal to zero, whereas the value of "determining the number of rpm is zero, indicating that the speed is not measured, it may be determined that the Hall sensor cannot measure the speed of rotation, since the Hall sensor is faulty, although the electric motor is activated.

Here, the value "determining the number of rpm" "0" indicates that the Hall sensor and the electric motor are normal, "1" indicates that the number of rpm ravneet is 0, and "2" indicates that the rpm is kept equal to 0 in the last two seconds, or that the rpm is not zero at least once during the remaining time.

The value of "determining the number of rpm is saved each time it is determined, and thereby the value of "determining the number of rpm"saved the last time, supported as a target of measurement of speed of rotation of the electric motor.

"Information is power off" includes information in relation to ends or not household appliance operation when the power is turned off after performing the specified operations, or without performing any part of the defined operations. For example, "Information on power off" can be 1, when the power is turned off due to power failure.

"Final" water level involves measuring the water level of the tank when the appliance shuts down.

"Time water drain error" indicates the time required to discharge (time of discharge), and, in particular, time of discharge, which is stored in the last time is stored in this information when an error occurs. The value of the "Time of discharge water when the error changes when discharge is performed, and the greater of the previously stored value and the new measured value is stored as the value of "Time is Liwa water when an error occurs". Thus, the maximum time required for draining, is stored as information of the time draining the water when an error occurs. I.e. the largest of times of discharge, measured when the drain is executed a certain number of times is stored as the value of "Time water drain error".

Namely, the value of "Time water drain error" indicates the largest of all work time required for draining, which are measured during operation of the drain, and thus the measured value of time discharge is maintained, when it exceeds the previously stored value, so that the maximum time of discharge is stored as the value of "Time water drain error".

"The maximum temperature IPM indicates the measured temperature of the motor controller, which applies a control signal to the motor. Although the motor controller generates and applies a control signal of the motor to the motor controller of the electric motor generates heat as it performs a large amount of calculations. The temperature controller of the electric motor is measured and recorded as the controller of the electric motor may be damaged when the temperature exceeds a certain level.

"Temperature error" includes information about the temperature of the second sensor, which measures abnormal temperature or temperature error from a variety of temperature sensors provided in the household appliance. For example, the temperature value when an error occurs "0" indicates that the abnormality is absent, "1" indicates a temperature sensor provided in the tank, "2" indicates a temperature sensor provided in the AF, and "3" indicates a temperature sensor provided in the channel. Here, the order or types of temperature sensors corresponding to the temperature values when the error occurs, can be changed according to the setting.

I.e. the temperature value when an error occurs "1" indicates that an abnormal temperature is a temperature sensor provided in the tank.

Here, each temperature sensor is provided in a household appliance, applies the data corresponding to the measured temperature to the main controller. The value you enter in the main controller, is not the measured temperature, but instead is appropriate 255 levels, which are classified values of resistance, current or voltage corresponding to the temperature.

When the value measured by the temperature sensor is equal to 0 or 255, the main controller may determine that the temperature sensor is defective the tion, because the values at 0 and 255 cannot be measured when the temperature sensor is working properly, and are measured due to problems in the wiring or connections. A value of 0 or 255 can also be applied to the main controller when the ambient temperature exceeds the range of temperature levels, which can be measured by the temperature sensor. In the case of washing machines such abnormal data is applied to the main controller when the temperature of the heater of the dryer exceeds the measurable range of the temperature sensor provided in the heater of the dryer, due to overheating caused by a failure of the fan. Thus, the main controller stores the information of the temperature sensor as information on temperature when an error occurs.

"The flag of the definition of bubbles when an error occurs" specifies, defines, or no bubbles when the error occurs, and is set when the bubbles is determined, and is reset when the bubbles are removed.

"Voltage error" indicates the voltage value measured when an error occurs. In General, the measured voltage value is not stored as the value of the "Voltage error". Instead, the measured voltage value is converted into one of many Uro is it on classified measured values of voltage, and the converted level is stored as the value of the "Voltage error".

"The number of rpm of the motor of the fan indicates the rotation speed of the electric fan, when a code error occurs. The rotation speed of the electric motor of the fan is measured before the electric fan is deactivated, and the motor fan is deactivated after the measured rotational speed is stored as the value of "the Number of rpm of the motor fan.

In particular, when the transition to the stage of cooling, the rotation speed of the drying fan in the washing machine is measured and stored as the Number of rpm of the motor fan.

"The flag of the re-supply of water" is set during the re-supply of water and is reset when re-supply of water is terminated. The value of the Flag re-supply of water" is stored when an error occurs or when the work is completed. The value of the Flag re water supply" is defined based only on whether or not the re-supply of water, regardless of re-supply of water during washing or rinsing.

"The state flag of the bimetallic element door" stores the on/off state of bimet lifestage element on the door, when associated with a door error occurs.

The data used in the overall operation of the washing machine, as described above, temporarily stored and updated if necessary, and stored in memory when an error occurs or when the operation completes.

Diagnostic data includes data elements corresponding to operations that are stored according to operating modes.

On the stages of the wash cycle time supply of wash water, the temperature of the wash water, the flag determination bubbles in the wash, flag low voltage when washing, the flag switching valve for washing and flag forced shutdown of the heater is stored as diagnostic data of the wash cycle. These data items are temporarily stored and updated during the wash cycle and stored in memory when the washing is completed.

Here, time data feed wash water "Time W water supply" is the time required for supplying water to the primary water supply, i.e. the time required until such time as the water supply is not completed after the water begins. The stored data of the temperature of the wash water include a first temperature of wash water Temperature water W0 and the second temperature of the wash water Temperature water W1". Here, the temperature of tank, when a slave is the beginning, is stored as the first wash water temperature and the temperature of the tank immediately after the initial water supply is completed, is stored as the second temperature of the wash water. I.e. the first temperature of the wash water Temperature water W0 is the temperature of the tank, which is measured when the work begins, i.e. when the water flow starts. First, the temperature of wash water is not measured when the water supply is resumed after termination. On the other hand, the second temperature of the wash water Temperature water W1 is the temperature of the tank, which is measured immediately after the initial water supply is completed. The temperature of the tank can be considered as the temperature of the wash water, as the temperature of the tank varies depending on the temperature of the wash water when the water supply runs. Then, whether or not the condition of the water supply, sensor, etc. is defective is determined by comparing these two temperatures wash water.

Flag definitions bubbles when washing specifies any or no bubbles during the wash and spin cycle in the washing mode, and can be set equal to "1"when the bubbles appear, and be set equal to "0"when the bubbles do not occur. Flag low voltage when washing is set when a low voltage is introduced. The flag switch klapa is and for washing is the flag associated with erroneous connection of valves supply of hot and cold water. The flag of forced shutdown of the heater is set to the value indicating that, disabled or not force the heater on the basis of time of heating. In particular, forced disconnection of the heater is saved as a history of forced shutdown of the heater due to time overheating and forced shutdown of the heater due to the absence of temperature change. When the heater is turned off at least once, the flag is forced off of the heater is set to "1", indicating that the forced disconnection of the heater occurs.

Diagnostic data mode rinsing include water for rinsing, the temperature of the water for rinsing, the flag determination bubbles when rinsing, flag low voltage when rinsing and information main valve for rinsing and temporarily stored and updated at the moment, when rinsing is performed or when rinsing is completed, and finally stored in memory, when rinsing is completed.

The time required to supply water for rinsing, is saved as the time of supply of water for rinsing, similar to the wash cycle. When rinsing the issue is neetsa repeatedly, the maximum from a set of measured times of water supply for rinsing is saved as the time of supply of water for rinsing. These temperature water for rinsing include a first temperature of water for rinsing and the second temperature of the water for rinsing, which are the temperatures of the tank, measured, respectively, before and after water supply, similar to the wash cycle. The temperature difference between before and after the water supply can be determined by using the first and second temperatures of water for rinsing.

Flag definitions bubbles when rinsing is set or cleared according to any or no bubbles during rinsing. Flag low voltage rinse is set when a low voltage is formed during rinse or spin in rinse mode. Information main valve for rinsing includes information indicating that is the main valve, used for the final rinse, valve cold water supply or valve hot water.

Diagnostic data of the drying mode by pressing include the value of the attempt counter mode drying wringer "Counter attempts UB", the load is relatively wet underwear, the offset value, the target rotation speed, maximum speed, flag definitions puzyrko the drying wringer and flag low voltage when drying wringer and stored in a moment, when drying is pressed or when the drying mode by pressing completes.

First, the value of the attempt Counter UB" is described as follows. Tank or drum may face housing the washing machine, when drying is pressed, depending on how the tank is tilted due to linen for washing. Large eccentricity linen for washing can lead to loud noise and makes high-speed drying with wringer impossible, and may damage the washing machine. Accordingly, the degree of balance or imbalance (or eccentricity) is measured before drying, extraction is performed. When the degree of unbalance or eccentricity is large, the washing machine does not start immediately drying with wringer and performs an operation for untangling and uniform redistribution of linen for washing. I.e. data concerning the attempt Counter UB" indicate the number of times the washing machine tried to move to the stage of drying, pressing, because she could not perform the operation of drying is pressed due to the large eccentricity. It is proportional to the number of times the washing machine performs the measurement of the eccentricity and detangling linen for washing.

Data loading Level relatively wet underwear" indicate the number is the creation of guest Laundry, measured for the last time before high-speed drying, extraction is performed. Because the amount of Laundry for washing, measured when the washing starts, is the amount of a dry linen Laundry facilities, number of wet linen for washing before drying, extraction is performed, converted and stored as data load, relatively wet underwear".

The amount of Laundry for washing can be classified on many levels, for example, very small, small, medium, normal, high, very high level and a one-time boot. "Offset" is the value to set the target rotation speed during drying, pressing, and the target rotation speed is reset on the basis of the eccentricity (or the degree of imbalance), regardless of the initially introduced functional settings. The maximum speed is the value measured when the final drying, extraction is performed.

Flag definitions bubbles when drying wringer associated with the any or no bubbles during drying, pressing, and flag low voltage when drying wringer indicates, is formed or not low tension during the drying cycle.

Diagnostic data of drying include the lowest water level is scetchy the operations of the heater of the dryer, the lowest drying temperature, the rotation speed of the motor, the lowest voltage, the drying time, the flag of the maximum speed of rotation of the motor fan (rpm) and flag low voltage when dried and stored when the drying is performed or when the drying is completed.

The lowest water level is the lowest level of water measured up until the drying is not completed when the initial discharge is completed after entering the drying mode. The count of the operations of the heater of the dryer is the number of operations on and off the heater of the dryer, and the lowest temperature drying is the least of the temperature values in the channel, measured immediately before the transition to the stage of cooling.

The rotation speed of the electric fan "the Number of rpm of the motor of the fan" is the measured value of the rotation speed of the drying fan of the washing machine during the transition to the stage of cooling. The lowest voltage of drying is the lowest of the voltages measured during the drying mode after entering the drying mode. Drying time is the time measured after pre-drying in the drying mode wringer. Maximum flag speed of rotation of the electric fan is set when the velocity of the rotation, measured during operation of the fan motor exceeds a predetermined speed, and flag low voltage when drying is set when a low voltage is provided in the drying mode.

Module 260 diagnostics diagnose the problem with using such data, included in the technical information, and extracts the solution for this issue.

Not only the data according to the operations of the household appliance, but also the count of occurrences of errors in household appliance and configuration data input via the pointing device 117, are included as diagnostic data in the technical information.

Count occurrences of errors include the number of occurrence of errors for each error code, the number of operations of the household appliance, the number of operations of the washing tank of a washing machine, etc. Data settings include settings associated with the mode of washing, counter operations rinse, language to use, the application of steam, the volume control, the intensity of drying, pressing and temperature of the wash water.

The main controller 141 stores such diagnostic data as the technical information in memory. When the appliance enters predictive diagnostics in response to the user input, the main pin is Oller 141 reads the stored diagnostic data and creates technical information and the encoder 142 encodes technical information to form a digital signal in a predefined format. The generated digital signal is applied to the modulator, which converts the digital signal into a combination of predefined frequency signals. The device 160 audio output displays a combination of predefined frequency signals as a predetermined sound signal.

5 is a flowchart of the sequence of operations illustrating a method for outputting an audio signal that includes technical information for the household appliance according to the present invention.

As shown in Figure 5, when the power button the power button function setting household appliance is performed according to the input data, and household appliance operates according to the settings screen (S310). Household appliance stores the data generated, and the data measured during the work of the household appliance.

When abnormality occurs during operation of the household appliance (S315), household appliance stops working and displays an error (S325). When the abnormality does not occur in the course of work, household appliance, household appliance continues to work according to the setup (S320).

Household appliance goes into predictive diagnostics, when the user operates the mod is LEM 130 choice provided the household device to enter a command Troubleshooting (S330). Here, when the user clicks in the module 130 of choice after the error appears, therefore, household appliance can also move in predictive diagnostics, when the user clicks in the module 130 of choice, without the occurrence of errors. However, household appliance may not go in predictive diagnostics according to the operation function keys pointing device 117 before the module 130 selection is entered.

The main controller 141 household appliance stores temporary data saved in the device 146 storage pamyati and collects diagnostic data stored in the memory 145, and applies the collected diagnostic data to the encoder 142. The encoder 142 adds the version information and the product number to the diagnostic data to generate technical information (S335).

The encoder 142 generates a digital signal in a predefined format after encoding technical information and applies the digital signal to the modulator 150. The modulator 150 enables the output frequency signal corresponding to a logical value of the digital signal, the device 160 audio output. Accordingly, the audio signal, which includes technical information,is output from the device 160 audio output (S340).

The audio signal output is thus introduced into the portable terminal 80, which connects to the service center 200 through the communication network or the telephone network, and the input audio signal is transmitted to the service center 200. The service center 200 performs fault diagnosis for household appliance using a sound signal.

6 is a flowchart of the sequence of operations illustrating a method for storing data in a consumer appliance.

As shown in Fig.6, the functional configuration household appliance is inserted through the pointing device 117, and a key start then pressed (S350). The main controller 141 initializes the stored data elements (S335), and stores the initial values of data elements (S360). The initial value of a specific diagnostic data is not specified if necessary.

For example, referring to the attributes of table 1, the initial value of the counter storing the number of operations or the number of errors is not specified, but instead, the counter value is accumulated (i.e. stored stacked), with initial values of the diagnostic data regarding the state information, General information, washing, rinsing, wringing, drying, error code, and options are specified.

When a code error occurs in the previous operation, the corresponding data are supported without initialization.

The main con is the roller 141 applies a control command to the driver 180, and driver 180 allows appliance to operate according to the functional setting. When the household appliance is a washing machine, the washing machine performs a washing mode according to the functional setting (S365).

In the procedure, in which washing is performed after the water supply, the receiving unit 170 measures the water temperature, water level and speed of rotation of the motor and uses the measured values to the main controller 141 or driver 180. The main controller 141 stores the data generated, and the data measured during the wash cycle, the memory 145 or temporarily stores them in the device 146 data storage. For example, data stored during the wash cycle, include the time of supply of flush water, the temperature of the wash water, the flag determination bubbles in the wash, flag low voltage when washing, the flag switching valve for washing and flag forced shutdown of the heater. These data items are temporarily stored or updated during the wash cycle.

When an error occurs during the wash cycle (S370), the main controller 141 stores temporary data in the memory 145, and stores the error code corresponding to the error data associated with the error, and the data associated with the status information in the memory 145 (S430). Display device 118 turn which leads to the error according to the control command from the main controller 141 (S435).

When the wash cycle is completed normally, the main controller 141 stores associated with the regime of washing data temporarily stored in the device 146 storage of data as diagnostic data in the memory 145 (S375).

After the wash cycle is completed, the main controller 141 performs the rinse mode (S380). The mode of washing is performed by repeating the procedure of water, rinsing and wringing 2-4 times. Data generated or measured at each stage of rinsing, are stored in the memory 145 or temporarily stored in the device 146 data storage.

For example, diagnostic data on rinsing include water for rinsing, the temperature of the water for rinsing, the flag determination bubbles when rinsing, flag low voltage when rinsing and data from the main valve to rinse.

When an error occurs during the rinse mode (S385), the main controller 141 stores temporary data in the memory 145, and stores the error code corresponding to the error, and the data associated with an error in the memory 145 (S430). The display device 118 displays an error according to the control command from the main controller 141 (S435).

When rinsing is completed normally, the main controller 141 stores associated with the regime rinse the data temporarily stored in the devices 146 data storage, as diagnostic data in the memory 145 (S390). Although diagnostic data on rinsing stored in memory 145 after the rinse mode is finished, the portion of the diagnostic data can also be stored in the memory 145 during the rinse mode.

When the phases of the rinse mode is finished, the mode of drying is pressed (S395).

The driver rotates 180 tank or drum at high speed to remove water from the linen for washing. Here, data on the drying wringer, formed during the drying mode wringer, temporarily stored in the device 146 data storage, or stored in memory 145.

Diagnostic data of the drying mode by pressing include the value of the attempt counter mode drying wringer "Counter attempts UB", the load is relatively wet underwear, the offset value, the target rotation speed, maximum speed, flag definitions bubbles when drying wringer and flag low voltage when dried with a spin cycle.

When an error occurs during the drying mode by pressing (S400), the main controller 141 stores temporary data in the memory 145, and stores the error code corresponding to the error, and the data associated with an error in the memory 145 (S430). The display device 118 displays an error according to the control command from the main con is the roller 141 (S435).

When the drying mode by pressing is completed, the main controller 141 stores the temporarily stored data as the diagnostic data of the drying mode by pressing in the memory 145 (S405).

After the drying mode by pressing is completed, the main controller 141 determines the set or not the drying mode. When the drying mode is set, the main controller 141 performs the mode of drying to remove water or moisture from linen for Laundry according to the setup (S415). The main controller 141 stores associated with the mode of drying data in the memory 145 or temporarily stores the data in the device 146 data storage.

When an error occurs during the drying mode (S420), the main controller 141 stores temporary data in the memory 145, and stores the error code corresponding to the error, and the data associated with an error in the memory 145 (S430). The display device 118 displays an error according to the control command from the main controller 141 (S435).

When the drying mode by pressing is completed, the main controller 141 stores the temporary data associated with the mode of drying, as diagnostic data in the memory 145 (S405).

As described above, the diagnostic data associated with each mode of washing, rinsing, drying, pressing and drying, are stored in the memory 145 when the mode is performed, or after the mode is terminated, and General d is installed is stored in the memory 145 if necessary, or directly after the formation of the shared data. In addition, when an error occurs, the associated data are stored.

When all the operations are completed, the main controller 141 in conclusion, stores diagnostic data associated with all operations household appliance (S425).

When working household appliance terminates normally according to the functional setting, or when an error occurs, the main controller 141 stores the data and terminates the household appliance (S440).

On the other hand, when the function setting is changed when the appliance operates, as described above, the main controller 141 updates the data according to the change. However, when the washing mode is changed, the main controller 141 can initialize the data.

Diagnostic data stored as described above, are used as technical information, when the appliance enters predictive diagnostics, if the module 130 of choice is introduced, as described above with reference to Figure 5, and is output as a predetermined sound signal through the device 160 audio output after the implementation of the processes of coding and modulation. The diagnostic server of the service center 200 receives and demodulates the sound signal output to extract technical information, and analyzes a variety of diagnostics is static information, included in the technical information to diagnose faults for household appliance.

7 is a flowchart of the sequence of operations illustrating a method for initializing data in the household appliance.

As shown in Fig.7, when the function setting is entered and the button start is pressed, as described above (S450), the main controller 141 increases the counter value indicating the count of the operations after the errors of the diagnostic data (S455). Here, the value of the counter operations after the error indicates the sequence of current operations after the error occurs, and is incremented every time when the button start is pressed. I.e. the value of the counter operations after an error is incremented when the button start is pressed after an error occurs. When the count of the operations after the error is equal to 3, it may indicate a third operation after an error occurs. Here, the time when the count of the operations after the error persists, can be changed.

The main controller 141 determines that the initialization data at the preliminary stage (S460), and compares the value of counter operations after an error with a reference value of the counter when the data initialization is not performed (S465). When the count of the operations p the following error is equal to or less than the reference value counter, the main controller 141 supports diagnostic data corresponding to the time when the error code occurs without initialization (S470). For example, when the reference counter value is equal to 3, the main controller 141 supports diagnostic data corresponding to the time when the error code occurs until the third operation is not performed after an error occurs.

When the count of the operations after the error is larger than the reference count value, the main controller 141 initializes the data (S475). Nevertheless, the main controller 141 supports diagnostic data associated with the meter, without initialization.

When the preliminary phase is complete, the appliance operates according to the introduced functional configuration (S480).

The main controller 141 temporarily stores data generated during the work of the household appliance, device 146 storing data and determines the expired or not the initial time after the work starts (S485). When the start time has not elapsed, the main controller 141 determines that the data temporarily stored in the device 146 storage data are not valid, and thus maintains the state of the temporary storage of data. When the starting time has elapsed, the main controller 141 determines that the data, the belt is stored in the device 146 data storage, are valid, and thereby stores the temporarily stored data as the diagnostic data in the memory 145 (S490).

When a code error occurs in the course of work household appliance (S500), or when an error code occurs before the starting time has expired (S520), the main controller 141 stores the data associated with the error, temporal data and the error code (S525). Since the new error occurs, the main controller 141 initializes the counter operations after an error (S530), and displays a warning error (S535).

Household appliance stops working when the error is thrown (S515).

Up until the specified operation is not completed without code error (S505), household appliance operates according to the configuration, and data generated or measured during operation, are stored as diagnostic data in the memory 145 (S480-S505).

When the work is completed, the diagnostic data are saved (S510), and household appliance stops working (S515).

Fig is a flowchart of the sequence of operations illustrating a method for storing data according to the lore of errors household appliance.

As shown in Fig when button start is pressed to allow appliance to begin, first, the main controller 141 determines that the imp is replaced or not the initialization data at the preliminary stage (S540), compares the value of counter operations after an error with a reference value of the counter, as described above, when the data initialization is not performed (S545), and initializes the data when the count of the operations after the error exceeds the reference value of the counter (S550).

When the data initialization has completed, the main controller 141 working with a domestic appliance according to the configuration as described above with reference to Fig.7 (S555), and stores the data in the course of work as diagnostic data (S560). Here, when a code error occurs during operation, the main controller 141 stores the error data, and temporary data (S580), initializes the counter operations after an error (S610), displays an error warning (S615) and exits (S630).

The main controller 141 stores the data generated during the work of the household appliance without error, as diagnostic data (S555-S570), and finally stores the diagnostic data when the operation completes (S810), and then crashes (S630).

On the other hand, when the count of the operations after the error is equal to or less than the reference value counter, the main controller 141 supports previous data (S585).

I.e. the main controller 141 working with a domestic appliance according to the setup without initialization data while maintaining diagnostic data is x, stored in the previous operation (S590).

The main controller 141 temporarily stores data generated or measured during household appliance, device 146 storage (S595). Here, the main controller 141 maintains the state of the data storage device 146 data storage without storing them in memory 145.

When a code error occurs during operation (S600), the main controller 141 updates the previous data or initializes diagnostic data associated with the error to save diagnostic data associated with the new error in the memory 145 (S605). After initialization, the counter operations after an error (S610), the main controller 141 outputs the error warning (S615) and then crashes (S630).

When no errors occur during operation, the main controller 141 allows appliance to continue the work in accordance with the setting until then, until it crashes (S620), and temporarily stores the data in the course of work (S590-S600).

When the appliance shuts down without errors supported previous diagnostic data, the main controller 141 discards the temporarily stored data and supports previous data (S625).

I.e. the value of the counter operations after the error is equal to or less than the reference value counter when registory error is present (i.e. when the error occurs), the main controller 141 supports previous data up until a new error does not occur, and initializes the data associated with the error occurs when the value of counter operations after the error exceeds the reference value of the counter.

Thus, the data corresponding to the time when the error occurs are supported as long as the number of operations that performs a household appliance, does not reach the reference value counter, or up until a new error does not occur, and the corresponding sound will be output when the appliance enters predictive diagnostics in response to the input module 130 of the selection.

Fig.9 is a flowchart of the sequence of operations illustrating a method for storing data in response to the power-down household appliance according to the present invention.

As shown in Fig.9, household appliance 101 operates according to the input setting (S640).

For example, when the household appliance is a washing machine, washing machine sequentially performs the modes of washing, rinsing and drying with wringer according to the input mode of washing, water temperature, configuration options, a certain quantity of linen for Laundry or a certain eccentricity. Here, the main controller 141 initializes the operating data when the mu is a necessity before as the washing machine starts working. However, previous diagnostic data, the background of which must be maintained, for example, associated with the error data or the data counter values are supported without initialization.

Data generated during the operation are stored as diagnostic data in the memory 145 or temporarily stored in the device 146 storing data in at least one of the time, when the washing machine is not starting the work, the time when each operation mode is completed, the time when all the operations are completed, or the time when the data is generated, depending on the type or attribute data (S645).

For example, data associated with the mode of washing, can be stored in the device 146 temporary storage of data when the data is generated, and then can be stored as diagnostic data in the memory 145, when the wash cycle is completed.

Here, when the power-off command is entered at the moment when the washing machine does the work (S650), the main controller 141 supports the diagnostic data stored in the memory 145 (S655), and stores temporary data associated with the current operation to be executed, which is stored in the device 146 storage of data as diagnostic data in the memory 145 (S660).

For example, when the command is as power-down is entered in the moment, when the washing machine performs a rinse mode, the main controller 141 supports the diagnostic data stored in the memory 145, unchanged and reads the timing data associated with the regime rinsing of devices 146 data storage and stores the read data in the memory 145. Here, the main controller 141 allows the washing machine to stop working.

In addition, the main controller 141 stores the operational data, for example, the state information associated with the current running operating mode associated error code, information associated with options, etc. as diagnostic data in the memory 145 (S665). When the washing machine is in rinse mode, the main controller 141 stores, as state information, information indicating that the wash cycle is completed, and information indicating that the rinse mode is currently running. Here, the operating data stored in the memory 145, also includes records associated with the cessation of work and off the washing machine in response to a power-off command.

The main controller 141 supports the initial values of the data phase of work, which is not actually performed, although it is set to run when the washing machine starts the initial operation (S670).

When the data storage is completed, as described above, the main controller 141 turns off the household appliance in response to a power-off command (S675).

Figure 10 is a flowchart of the sequence of operations illustrating a method for storing data according to the command stop in the household appliance according to the present invention.

As shown in Figure 10, household appliance 101 operates according to the input configuration as described above (S680). Before the washing machine starts, the operating data are initialized, and the data associated with the error, etc. are supported without initialization, as described above.

Data generated at the same time as the appliance operates according to the configuration, it is saved as a temporary data device 146 storage or stored as diagnostic data in the memory 145 in the specified time according to the type of data (S685).

In particular, data generated during operation, are stored in the memory 145 or temporarily stored in the device 146 storing data in at least one of the time, when the washing machine is not starting the work, the time when each operation mode is completed, the time when all the operations are completed, or the time when the data is generated, depending on the data type. For example, data associated with the mode of washing, can be stored in the device is 146 temporary storage of data, when the data is generated, and temporary data in the device 146 storage data can then be stored as diagnostic data in the memory 145, when the wash cycle is completed.

Here, when the stop command is entered at the moment when the washing machine does the work (S690), the main controller 141 terminates the current operation of the household appliance (S695) and supports diagnostic data stored in the memory 145 (S700).

The main controller 141 stores the temporary data associated with the current stage of work, which is stored in the device 146 storage of data as diagnostic data in the memory 145 (S705).

The main controller 141 stores the operational data includes status information associated with the work of the household appliance, as diagnostic data in the memory 145 (S710). When the washing machine is in rinse mode, the main controller 141 stores, as state information, information indicating that the wash cycle is completed, and information indicating that the rinse mode is currently running.

The main controller 141 supports the initial data values associated with a process step that is not performed (S715).

When a predetermined time has elapsed after household appliance stops operating in response to input to the team stop that is, when the start command is not entered within a predetermined time or more after household appliance stops working (S720), the main controller 141 cuts power to the household appliance (S725).

When the restart command is entered after household appliance stops working, the main controller 141 performs the operation according to the functional setting. I.e. the main controller 141 resumes stopped working step, and sequentially performs the following operations according to the functional setting.

11 is a flowchart of the sequence of operations illustrating a method for storing data according to the stopping power in the household appliance according to the present invention.

As shown at 11, household appliance 101 operates according to the configuration as described above (S730). Data generated at the moment when the appliance operates, are stored in the memory 145 or saved as temporary data device 146 storage (S735).

When the power is lost during operation of the household appliance (S740), for example, when power is not supplied due to a power outage or when power is forcibly turned off to protect the appliance, as a result of violations of food, the main controller 141 stores the diagnostic data vkluchaysya information supply concerning violations of food or a power outage and status information regarding the current operation in the memory 145 (S745).

Here, since the current stored in the power supply appliance remains after the power is lost, the main controller 141 stores the diagnostic data using the stored current.

When saved, the current remains in the power circuit (S750), the main controller 141 stores the diagnostic data by saving the data as described above (S745-S750).

When no current is stored in the power supply, all operations household appliance automatically terminated, and the power automatically turns off due to the discharge (S755).

Here, it is preferable that most of the operations household appliance immediately stopped, and the current stored in the power supply, was used to store data when power is terminated for the reasons described above.

Fig is a flowchart of the sequence of operations illustrating a method for storing data according to the operating mode of the domestic appliance according to the present invention.

As shown in Fig, household appliance 101 operates according to the configuration as described above (S760). Data generated at that time, as household appliance works, temporarily stored in the device 146 data storage, or stored in memory 145 in the specified time, depending on the data type (S765).

The main controller 141 to take the AET information of each component of the household appliance, for example, pressure or temperature during operation of the household apparatus 101 via the receiving device 170. Here, the main controller 141 determines the state of the household appliance according to the temperature value received via the receiving unit 170. When the received temperature value is equal to or exceeds the reference value (S770), the main controller 141 applies a forced power off to the power device (S775).

Power unit forcibly turns off the power in response to a control command from the main controller 141. Household appliance 101 terminates due to involuntary termination power.

Here, although the power is lost, the appliance 101 stores the diagnostic data includes status information, information power and the temperature information in the memory 145 using the stored power remaining in the power circuit (S785).

When saved, the current remains in the power circuit (S790), the main controller 141 continues to save data described above (S785-S790).

When saved, the current does not remain in the power supply, all operations cease, and the power switches off (S795).

SUBSTANCE: previously a reaction of a knowingly good system is registered in the interval at reference points, and integral estimates of output signals of the system are determined repeatedly (simultaneously) for integration parameter values. For this purpose at the moment of test signal supply to the inlet of the system with rated characteristics, simultaneously integration of control system signals is started for parameters of integration in each of the reference points with weights, by supplying of control system signals to the first inlets of the multiplication blocks. Exponential signals for integration blocks are supplied to the second inlets of the multiplication blocks. Output signals of the multiplication blocks are supplied to the inputs of the integration blocks. Integration is completed at the moment of time. Estimates of output signals produced as a result of integration are registered, the number of the system blocks is fixed, elements of topological links of each block within the discrete system for each reference point are determined, elements are determined from many values {-1,0,1}, the value - -1 is defined, if the sign of signal transfer from the output of the i block to the j reference point is negative.
