In accordance with the program stored in the memory of computer 14 remote control 1 on block 2 are given the code of the parcel under which the unit 2 generates at its output the address codes for the control units 3, 4, 5 and 9. In the initial state outputs 3-1, 3-2 and 3-3 unit 3 control modes signals UE is Alenia switches 7 and 13, unit 6 the formation and reception of different code block 12 convert the DC voltage is missing.

Before the health check object 10 control is self-control system in the following order.

The operator of block 15 command set console 1 typed command, under the action of which the transmitter 14 of the remote controller 1 starts program, which provides grant calculator 14 code of parcels on the block 2 code generation control. Then unit 2 generates at its output the address information code of the parcel under which the system goes into a mode of self-control.

The unit 3 control modes under the action code packages from unit 2 generates a 3-1 output signal that transitions:

Consider the system in the self-control of measuring frequency channels block 8 meters and block 12 conversion of DC voltage.

Block 18 of the reception code unit 4 selects a code packages from the output unit 2. Adopted by the block 18 block 4 code is parsed and then outputted to the Converter 19(19n), where code is converted to the specified value DC voltage on the inverter output 20(20n) is formed by a signal of variable frequency. Moreover, variable frequency, there is a value of the reference code, which is stored in the memory of the computer 14 of the panel 1. The dal frequency signal passes through the block 21(21n) galvanic isolation on the output unit 4 and through the switch 7 is supplied to a block of 8 meters. Unit 21(21n) block 4 is required for galvanic isolation of the supply system and power supply unit 8 meters and object 10 of the control which requires its operating conditions. Frequency AC signals values from the output unit 4 through the switch 7 receives the inputs of the frequency measuring unit 8. Converters frequency measuring channels unit 8 converts the frequency signals of the specified values at a frequency proportional to the binary code, which is relevant to the existing form (sequential unipolar or bipolar) is supplied from the output unit 8 to the transmitter 14 of the remote control 1.

In addition, the block 8 meters produces a specified DC voltage proportional to the input specified frequency signals.

To verify the functionality of the block 8 meters and block 12 convert the DC voltage, as was mentioned above, the output of block 4 is set to the frequency setpoint signal, which is supplied to a block of 8 meters, where it is converted into binary code and constant voltage set value, which is supplied to the block 12 conversion of DC voltage. The binary code that is proportional to a given input frequency from the output unit 12 conversion of DC voltage and block 8 meters is compared with the specified control code, which is stored in the memory of the computer 14 of the panel 1. If the code from the output unit 12 and the output unit 8 meters meets the control code transmitter 14 with the given tolerance, the measuring frequency channel block 8 and block 12 are intact. And if the value of the binary code from the output of block 12 and block 8 does not meet the control code with the given tolerance, the measuring frequency channel unit 8 or unit 12 is broken and the system needs repair. The results of self-monitoring measuring frequency channels block of 8 meters and a block 12 of converting DC voltage recorded in the memory of the computer 1 and are output to the display unit 16 of the panel 1.

After checking the function of the measuring frequency channels unit 8 in accordance with the program of self-control is controlled by the efficiency of the channel control circuits of sensor unit 8. The sequence control circuit of the sensor unit 8 frequency meters is conducted in the following order.

Command transmitter 14 remote control 1 on block 2 receives the code of the parcel under which the unit 2 generates at its output the address codes, which takes the unit 3 control modes. After analysis of the received code block 3 at its output 3-2 generates signals that turn off imitators frequency sensor unit 4 from the frequency of the input unit 8. At the output of block 8 is formed code sending, for example, in the form of binary code to the transmitter 14 of the panel 1, which indicates a breach of the chain of frequency sensors. The transmitter 14 1 remote code sending unit 8 measures compares with the specified code value, which is stored in the memory of the computer 14 of the panel 1, and if it meets the specified code value, the channel control circuits frequency sensor unit 8 is good, and if you do not respond, then the channel control circuits frequency sensor unit 8 is defective. The system needs repair.

After checking channel availability control circuits frequency sensor unit 8, the signals from the output 3-2 block is 3 to remove and frequency signals from the output unit 4 through the switch 7 to the inputs of the block 8.

The results of the control channels of the control circuits of the frequency sensor unit 8 recorded in the memory of computer 14 and is output to the display unit 16 of the panel 1.

Let's consider a system of self-control measuring an analog channel unit 8. Unit 5 managed imitators of analog sensors selects code packages from the output of block 2, which provide analog signals setpoint to the output unit 5. Adopted by the unit 5, the code is parsed and then issued to the relevant converters, where the code is converted to the specified value DC voltage, AC voltage or resistance, which are received through the switch 7 in block 8 of the probes. Converters analog measuring channels unit 8 converts the analog signals of the given value in proportional to the binary code that is in the appropriate form (sequential unipolar or bipolar) comes from the output unit 8 to the transmitter 14 of the remote control 1.

The binary code that is proportional to a given analog signal from the output unit 8 is compared with a specified ID, which is stored in the memory of the computer 14 of the panel 1. If the code from the output unit 8 answers given code value with the given tolerance, the measuring of the analog channels of the block 8 are intact. And if the value of the binary code output unit 8 does not meet the specified code value with a specified tolerance, the measuring of the analog channels of the block 8 is defective and the system needs repair. The results of the self-control of measuring an analog channel unit 8 recorded in the memory of computer 14 and is output to the display unit 16 of the panel 1.

After checking the health of measuring an analog channel unit 8 according to the program of self-control is controlled by the efficiency of the channel control circuits analog sensor unit 8. The sequence control health channel unit 8 to the control circuits of analog sensors is conducted in the following order.

Command transmitter 14 remote control 1 on block 2 receives the code of the parcel under which the unit 2 generates at its output the address codes, which takes the unit 3 control modes. After analysis of the received code block 3 at its output 3-3 generates signals that disable simulators analog sensors unit 4 from the input unit 8. At the output of block 8 is formed code sending, for example, in the form of binary code to the transmitter 14 of the panel 1, which shows the violation of the circuits of analog sensors. The transmitter 14 1 remote code sending unit 8 compares with the specified code value, which is stored in the memory of the computer 14 of the panel 1, and if it meets the specified code value, the control channels of analog circuits the sensor unit 8 healthy, and if you do not respond, then the channel control circuits analog sensor unit 8 is defective. The system needs repair. After the health check channel control circuits analog sensor unit 8, the signals from the output 3-3 unit 3 are removed and the analog signals from the output unit 5 are passed through the switch 7 to the inputs of the block 8.

The results of the control channels of the control circuits of the analog sensor unit 8 recorded in the memory of computer 14 and is output to the display unit 16 of the panel 1.

As was mentioned above, the unit 3 control modes under the action code packages from unit 2 generates a 3-1 output signal that transitions of block 6 of the formation and reception of different code in dialog mode with the transmitter 14 of the panel 1. Thus the output of the channel forming different code block 6 is connected to the input of the receive channel of different code block 6.

According to the program of the control computer 14 of the remote controller 1 generates code parcel to channel the formation of different code block 6, the output of which appears different code set value that is fed to the input of the receive channel of different code block 6. From the output of the receive channel of different code block 6 to the input of the transmitter 14 remote control 1 enters a code in a form suitable for reception by the transmitter 14. If the principle is th code calculator 14 panel 1 corresponds to the specified value code issued by the transmitter 14 to the channel forming bipolar code, block 6, block 6 of the formation and reception of different code intact, and if not, the block 6 is broken and the system needs repair.

The results of the self-channel unit 6 the formation and reception of different code recorded in the memory of computer 14 panel 1 and are output to the display unit 16 of the panel 1.

Further, according to the program of self-control checks whether the block 9 managed imitators of sensors-detectors, switch 13 and unit 11 receiving a single signal.

According to the program of the control unit 9 receives the appropriate code packages from the output of block 2 code generation control and generates at its output a single signal, for example, in the form of a DC voltage through the switch 13 are received in block 11 of the receiving individual signals. When receiving a single signal unit 11 generates at its output code packages that come to the transmitter 14 of the panel 1, which compares them with a predetermined code value.

If these code values are equal, then the system is OK, and if not, then the system is broken and needs repair.

The results of the self-control unit 9 managed imitators of sensors-detectors, switch 13 and unit 11 receiving a single signal to the fixed is carried out in the memory of computer 14 panel 1 and are output to the display unit 16 of the panel 1.

The results of the self-control of the entire system are formed in the form of, for example, the text of the Protocol and shall be printed in block 17 of the remote control 1.

This completes the self-monitoring system that covers all its parts.

After self-monitoring system and if it is good, check the health of the object 10 control.

Modern objects 10 control multi-function, i.e. generates various signals, for example, constant voltage, single tones (single team), different code depending on the operation algorithm and the values of the input signals from the simulated sensors. The signals from the simulated sensors simultaneously arrive at the inputs of the object 10 and control unit 8 meters.

Output code frequency and analog measuring channels of the block 8 may correspond to, for example, as specified physical values (rpm,%, temperature - °C, pressure kgf/cm2differential pressure kgf/cm2and so on) parameter, and the corresponding values of the input signal represented by the voltage (V) AC / DC, frequency (Hz) AC signal, etc. depending on the algorithm operation unit 8 meters.

The output DC voltage of the object 10 control is proportional to the change of the input signal from the imitators analogues of the x and frequency detectors.

Output a single signal (single command) object 10 control are issued upon achievement of the corresponding parameters as frequency and analog its limit, the alarm. Each issued by a single signal corresponds to, for example, a given physical value (momentum - %temperature - °C, pressure kgf/cm2differential pressure kgf/cm2and so on) parameter, which, in turn, corresponds to the set value of the binary code, which is stored in the memory of computer 14 1 remote control.

Therefore, the reference code value stored in the memory of computer 14 remote control 1 physical representation identical to the measured code obtained from the output of the unit 8 meters.

For example, the object 10 is given a single signal at an input frequency of 3000 Hz, which corresponds to the physical value of the engine speed "103%", which presents a set value of the binary code, which, in turn, as the reference is recorded in the memory of the computer 14 1 remote control.

When entering from the object 10 single signal "103%" engine speed to the transmitter 14 of the panel 1, the transmitter 14 of the panel 1 from the output of the same channel block 8 meter records the measured value of the binary code that corresponds to the physical value is Yu turns in "%". This value of the binary code is compared with a control code that corresponds to, for example, the level of turnover "103%" and resides in the memory of the computer 14 of the panel 1. Comparison of codes is determined by the health measuring frequency or analog channels of the object 10 control.

The health check object 10 control is performed in the following order.

The operator of block 15 command set console 1 assemble a team that will run the program evaluator 14 to test object 10 control. The transmitter 14 of the remote controller 1 starts program, which provides grant calculator 14 code of parcels to block 2 code generation control. Then unit 2 generates at its output the address information code of the parcel under which the system enters the mode of the test object 10 control.

In the initial state outputs 3-1, 3-2 and 3-3 unit 3 control modes control signals for the switches 7 and 13, block 6 of the formation and reception of different code block 12 convert the DC voltage is missing.

The signals from the outputs of the block 4 and 5 through the switch 7 receives the inputs of block 8 of the probes and the object 10 control signals from the first output object 10 control through the switch 13 is coming to the block 11 when the mA of single signals, and signals from the second output of the object 10 control proceed to block 12 conversion of DC voltage.

Let's consider a system for measuring frequency channels of the object 10. Block 18 of the reception code unit 4 selects a code packages from the output of block 2, which provide and the frequency change at the output of block 4. Adopted by the block 18 block 4 code is parsed and then outputted to the Converter 19(19n), where code is converted into the corresponding value of the DC voltage, which makes the output of inverter 20(20n) is formed by a signal of the appropriate frequency. Next, the frequency signal is sent through the block 21(21n) galvanic isolation on the output unit 4 and through the switch 7 is supplied to a block of 8 meters and object 10 control. Unit 21(21n) block 4 is required for galvanic isolation of the supply system and power supply unit 8 meters and object 10 of the control which requires its operating conditions. Depending on the code changes adopted by the unit 18 unit 4 changes the frequency signals of the channels, respectively, and block 4. Frequency signals from the output unit 4 through the switch 7 receives the inputs of the frequency measuring unit 8 and the object 10 control. Converters frequency measuring channels unit 8 converts the frequency signals at a frequency proportional or physical is dedicated to value "%" rpm binary code, which in the appropriate form (sequential unipolar or bipolar) is supplied from the output unit 8 to the transmitter 14 of the remote control 1.

At the same time the frequency signals from the output unit 4 receives the inputs of the object 10 to control the frequency of the measuring channels, where the frequency signal is converted into a proportional named binary code, which is then analyzed, for example, by algorithms tolerance control to ensure delivery of individual signals from the output of the object 10. And issued by a single signal corresponds to a physical parameter, for example, "%" momentum.

Single signals through the switch 13 are accepted by the unit 11, which generates at its output a code send to the transmitter 14 of the panel 1. When a message arrives in the code parcels unit 11 to the transmitter 14 of the panel 1 on the issuance of the object 10 single signal transmitter 14 remote control 1 registers the value of the binary code output unit 8. This value of the binary code is compared with a control code, which resides in the memory of computer 14 and corresponds issued by a single signal, and if it matches the control code with the given tolerance, then the issuance of a single signal measurement frequency channel of the object 10 is correct. This demonstrates the operability of the measuring frequency channel and the PRA is innosti its operation for forming and issuing a single signal by the object 10. And if the value of the binary code output unit 8 does not match the control code with the given tolerance, the measuring frequency channel is faulty and the object 10 in need of repair. The number of individual signals, which are issued to the measuring frequency channels of the object 10, depends on the algorithm of its operation.

In addition, the object 10 generates a DC voltage proportional to the input frequency signals.

To verify the functionality of the channels of the object 10, which generates a DC voltage proportional to the input frequency signals, at block 12 convert the DC voltage at the output of block 4 is set to the frequency setpoint signal which is also fed to a block of 8 meters, where it is converted into binary code. The binary code that is proportional to a given input frequency from the output unit 12 convert the DC voltage is compared with the code that comes from the output of the measuring frequency channel block 8. If the code from the output unit 12 corresponds to the code from the output of the measuring frequency channel block 8 with the given tolerance, the measuring frequency channel object 10 is operable. And if the value of the binary code from the output unit 12 does not match the code from the output of the measuring frequency channel block 8 with the given tolerance, then measuring the frequency channel of the object 10 is broken and it needs repair.

Verifying the issuance of single signals, the object 10 through the frequency channels can be also controlled by the computer 14 panel 1 according to codes received from the output unit 12 (for frequency channels which are issued by a single signal), and codes from the output of the measuring frequency channels of the block 8 at the time of receiving a single signal from the output of the object 10.

If the code from the output unit 12 at the time of issuance of a single signal matches the code from the output of the measuring frequency channel block 8 with the given tolerance, the measuring frequency channel of the object 10, which was given a single sound is serviceable. And if the value of the binary code from the output unit 12 at the time of issuance of a single signal does not match the code from the output of the measuring frequency channel block 8 with the given tolerance, the measuring frequency channel object 10 is broken and it needs repair.

After checking the function of the measuring frequency channels of the object 10 according to the program is controlled by the efficiency of the channels of the control circuits of the sensors of the object 10. The sequence of control channels of the object 10 by the control circuits of the sensors is performed in the following order.

Command transmitter 14 remote control 1 on block 2 receives the code of the parcel under which the unit 2 generates at its output the address code is, which takes the unit 3 control modes. After analysis of the received code block 3 at its output 3-2 generates signals that turn off imitators frequency sensor unit 4 from unit 8 and the object 10. At the output of block 8 is formed code sending, for example, in the form of binary code to the transmitter 14 of the panel 1, which indicates a breach of the chain of frequency sensors. If the channels of the object 10 by the control circuits of frequency sensors intact, from its output through the switch 13 will be issued single signals, which are received by the unit 11, and which, in turn, generates a code package, for example, in the form of binary code to the transmitter 14 of the panel 1, which indicates a breach of the chain of frequency sensors. The transmitter 14 1 remote code sending unit 11 compares the code sending unit 8, and if it corresponds to a code value of block 8, then the channel object 10 by the control circuits of the frequency sensor is working or if it does not, then the channel object 10 by the control circuits of the frequency of the sensors is defective. The object 10 in need of repair. After checking channel availability control circuits frequency detectors of the object 10, the signals from the output 3-2 unit 3 are removed and the frequency signals from the output unit 4 through the switch 7 to the inputs of the block 8 and the object 10.

Consider the system at stake is the control of analog measuring channels of the object 10. Unit 5 managed imitators of analog sensors selects code packages from the output of block 2, which provide for the issuance and change of analog signals at the output of block 5. Adopted by the unit 5, the code is parsed and then issued to the relevant converters, where the code is converted into a corresponding value of DC voltage, AC voltage or resistance, which are received through the switch 7 to the unit 8 measurement and the object 10. Depending on the code changes adopted by the unit 5 changes the analog signals of the channels at the output. Analog signals from the output unit 5 via the switch 7 receives the inputs of the analog measuring unit 8 and the object 10 control. Converters analog measuring channels unit 8 converts the analog signals into a proportional analog signals binary code, which is in the appropriate form (sequential unipolar or bipolar) is supplied from the output unit 8 to the transmitter 14 of the remote control 1.

At the same time analog signals from the output unit 5 receives the inputs of the object 10 to control analog measurement channels, where analog signals are converted into proportional to them binary code, which is further analyzed, for example, algorithms for tolerance control to ensure delivery of a single discrete signals from the output of the of byetta 10. Single signals from the output of the object 10 through the switch 13 are accepted by the unit 11, which, however, generates at its output a code send to the transmitter 14 of the panel 1. When a message arrives in the code parcels unit 11 to the transmitter 14 of the panel 1 on the issuance of the object 10 individual signals, the transmitter 14 of the remote controller 1 detects the value of the binary code output unit 8. This value of the binary code is compared with a control code, which is stored in memory of computer 14 and corresponds issued by a single signal, and if it matches the control code with the given tolerance, then the issuance of a single signal measurement analog channel object 10 is correct. This demonstrates the operability of the measuring analog channel and the correctness of its operation for forming and issuing a single signal by the object 10. And if the value of the binary code output unit 8 does not meet the control code with the given tolerance, then the analog measuring channel is defective and the object 10 in need of repair. The number of individual signals, which are issued analog measuring channels of the object 10, depends on the algorithm of its operation.

In addition, the object 10 generates a DC voltage proportional to the input analog signals.

To verify the functionality of the channels of the object 10, the cat is that given a constant voltage, proportional to the input analog signals, at block 12 convert the DC voltage at the output of block 4 is set to the specified analog signal, which is supplied also to the block 8 meters, where it is converted into binary code. The binary code that is proportional to a given analog signal from the output unit 12 convert the DC voltage is compared with the code that comes from the output of measuring an analog channel unit 8. If the code from the output unit 12 corresponds to the code of measuring an analog channel unit 8 with the given tolerance, the measuring analog channel object 10 is operable. And if the value of the binary code from the output unit 12 does not match the code from the output of measuring an analog channel unit 8 with the given tolerance, the measuring analog channel object 10 is broken and it needs repair.

Verifying the issuance of single signals, the object 10 analog channels can be also controlled by the computer 14 panel 1 according to codes received from the output unit 12 (for analog channels, which are issued by a single signal), and codes from the output of analog measuring channels of the block 8 at the time of receiving a single signal from the output of the object 10.

If the code from the output unit 12 at the time of issuance of a single signal corresponds to the ode from the output of measuring an analog channel unit 8 with a specified tolerance, the measuring analog channel object 10, which was given a single sound is serviceable. And if the value of the binary code from the output unit 12 at the time of issuance of a single signal does not match the code from the output of measuring an analog channel unit 8 with the given tolerance, the measuring analog channel object 10 is broken and it needs repair.

After checking the function of the measuring analog channels of the object 10 according to the program is controlled by the efficiency of the channels of the object 10 by the control circuits of analog sensors.

The sequence control health channel object 10 by the control circuits of analog sensors is conducted in the following order.

Command transmitter 14 remote control 1 on block 2 receives the code of the parcel under which the unit 2 generates at its output the address codes, which takes the unit 3 control modes. After analysis of the received code block 3 at its output 3-3 generates signals that disable simulators analog sensors unit 4 from unit 8 and the object 10. At the output of block 8 is formed code sending, for example, in the form of binary code to the transmitter 14 of the panel 1, which shows the violation of the circuits of analog sensors. If the channel control circuits analog sensor object 10 is OK, its output BU the ut issued a single signal, which through the switch 13 are accepted by the unit 11, and which, in turn, generates a code package, for example, in the form of binary code to the transmitter 14 of the panel 1, which shows the violation of the circuits of analog sensors. The transmitter 14 1 remote code sending unit 11 compares the code sending unit 8, and if it meets the code value for the block 8, the channel object 10 by the control circuits of analog sensors intact, and if not answered, the channel object 10 by the control circuits of analog sensors is faulty. The object 10 in need of repair.

After checking channel availability control circuits of analog sensors, the object 10, the signals from the output 3-3 unit 3 are removed and the analog signals from the output unit 5 are passed through the switch 7 to the inputs of the block 8 and the object 10.

In accordance with the control program object 10 unit 9 receives the appropriate code packages from the output of block 2 code generation control and generates at its output a single signal, for example, in the form of a DC voltage, which come before the object 10 control. When receiving a single signal from block 9 to the object 10 control uses the last of their algorithms tolerance control in the formation of single frequency signals and analog input signals and outputs a single signal through the switch 13 to the block 11 is of Riem single signals.

The block 11 generates at its output code signals to the transmitter 14 of the panel 1. When a message arrives in the code parcels unit 11 to the transmitter 14 of the panel 1 on the issuance of the object 10 single signals, the transmitter 14 of the remote controller 1 compares it with the control code, which is stored in his memory, which, in turn, ensured the formation of a team unit 2 to unit 9, and if it meets the control code, the issuance of a single signal measurement analog or frequency channel of the object 10 is correct. This indicates a healthy channel for receiving individual signals of the object 10. And if the value of the binary code output unit 11 does not meet the control code, the channel receiving a single signal is faulty and the object 10 in need of repair. The number of individual signals, which are issued to measuring analog or frequency channel of the object 10 in the presence of the input single signal from the output unit 9, depends on the algorithm of functioning of object 10.

In accordance with the control program of the object 10, the transmitter 14 of the remote controller 1 generates code parcel to channel the formation of different code block 6, the output of which appears different code set value that is fed to the input of the receive channel of different object code 10. The object 10 adopted different code analyses for which anomo algorithm, and the result of the analysis as specified code values produces different code to receive channel bipolar code block 6. From the output of the receive channel of different code block 6 to the input of the transmitter 14 remote control 1 enters a code in a form suitable for reception by the transmitter 14. If the received code calculator 14 panel 1 corresponds to a given code value, which is stored in the memory of the computer 14 of the panel 1, the receive channel and the formation of different object code 10 healthy, and if not, then the object 10 in need of repair.

The results of the test object 10 are fixed in the memory of computer 14 panel 1, are displayed on the unit 16 to display and print, for example, in the form of text protocols unit 17.

The present invention allows to extend the functionality and scope, as well as to provide a health check on the multifunction control objects, which will, in turn, reduce downtime, for example, an aircraft that uses the multifunction system control.

In addition, the system provides control of all its elements, which can, in turn, ensure the high reliability of the results of the inspection object 10.
