The invention relates to mechanical engineering and can be used in systems for the protection and management of load-lifting machines for the reception, processing, stockpiling and storage of operative and long-term information about the parameters of their work.

There is a method of measuring and recording the magnitude and time of lifting machines (cranes) by measuring the load and boom angle, impacts on special summarizing the motor in accordance with the results of these measurements and the subsequent registration of the number of revolutions of the motor and calculate calendar time [1].

The device for implementing this method comprises sensors of effort and boom angle, the outputs are connected to summing special motor with a gearbox, and a separate count calendar time [1].

The disadvantage of this method and the implementing device is the limited functionality, in particular due to the lack of registration load on the lifting bodies and the coordinates of the cargo relative to the crane.

There is also known a method of fixation of the characteristics of the load-lifting mechanisms, based on the measurement signals proportional to these characteristics, primary processing of the converted signals, together with prewar the tion stored signals, defining the procedure of this processing, the formation time interval and, in case of occurrence of signals proportional to the results of the initial processing of the converted signals and exceeding the preset threshold level in the generated time interval, storing their values and time of occurrence [2].

A device for implementing the known method contains performed with interrupt input digital computing unit, an information input of which is connected to the output of analog-to-digital Converter, the second bidirectional - input and output digital storage unit, sensors analog parameters of the crane is connected to the inputs of analog-to-digital Converter, sensors discrete parameters and signals on the work of the crane is connected to the third information input digital computing unit and the timer, outputs connected to the interrupt input of the digital computing unit and to the input of a digital storage unit [2].

This technical solution is the registration of all necessary parameters of load-lifting machines, as well as recording the time of occurrence of critical conditions.

However, the registration parameters is carried out only in case of exceeding the threshold level, which is a disadvantage of this JV is soba and the implementing device. In addition, this recorder is not provided overwrite (transfer) of the accumulated information in the personal computer for further processing.

More perfect and the closest to the invention is a method of registering the parameters of the hoisting machine by obtaining data on its analog and discrete parameters, their primary processing, transformation, and then write on the hoisting machine in the storage device, which is an integral part of the system (device, device) safety lifting machines, as well as copy or rewrite as necessary, the specified data stored in non-volatile memory, removable mobile media (meter reading, a reader of historical information, the copyist "black box" and so on) and then overwritten data from mobile media in personal computers for secondary processing [3].

The recording device (recorder) settings lifting machine that implements the known method and is the closest to the proposed contains sensors operating parameters hoisting machine and an electronic unit that includes a microprocessor computer (microcontroller) and the connected storage device (block telemetry memory), and the electronic unit is made with the discerning business is using to connect to its microprocessor in the transmitter, directly or through the device input/output information, removable mobile media (meter reading, a reader of historical information, the copyist "black box" and so on), as well as sensors of operating parameters to the microprocessor in the transmitter through the coordination, in particular through the specified or additional device input/output information or analog-to-digital Converter, with removable mobile media includes volatile memory and configured to connect to a personal computer [3].

In the specified way and realizes his device to register all the necessary operating parameters of the lifting machine, and rewrite (transfer) of the accumulated information with the help of a special removable mobile media in a personal computer for subsequent (secondary) processing.

However, there is no possibility of reverse overwrite the information with the mobile storage medium in a storage device of the electronic unit, which is a disadvantage of this technical solution. For this reason, in particular, is not possible using mobile media to transfer any data from personal computers or other mobile media info the information in the electronic unit, for example, for reprogramming under another type of lifting machine (to change the cargo characteristics or features off), to modify the algorithms of primary processing of information in the Registrar, or to write to the Registrar information about the previous lifting machine. If, for example, the Registrar of options for any reasons set on lifting the car, already in operation, for example after replacement of the Registrar, the data stored in the logger, in particular about the time machine will not be accurate, since registration is only since the installation of the Registrar on the hoisting machine without taking into account its previous achievements.

In addition, in the known technical solution is not protected accumulated information from accidental or intentional distortion during recording in mobile media, as well as during storage and when reading this information also personal computers. Not provided for restricting access to persons not entitled to work with the Registrar of parameters, for reading out stored data to a lifting machine and overwriting of a mobile carrier in personal computers.

The technical result, which is aimed proposed technical solution, which is:

- the possibility of recording data about the previous period of operation of loading the machine in a storage device located on the machine;

- increase the accuracy of the registration parameters of the hoisting machine by protecting the accumulated information from accidental or intentional distortion (to ensure the relevance of the data logger parameters) and detection of erroneous data;

exception access for reading out and processing the data logger settings, individuals who do not have such rights;

- enable reprogramming of parameters and algorithms as Registrar and electronic unit in which it is included, including changing the primary information processing in Registrar settings and features off (cargo characteristics) for the implementation of the electronic unit of the functions of the load limiting device.

In the method of registering the parameters of the hoisting machine by obtaining data on the parameters of its work, in particular by measuring, primary processing or conversion, and the subsequent entry using a microprocessor-based computer (microcontroller) in the storage device on the lifting machine, and copy or rewrite as necessary, the specified data stored in the mobile nose is tel information (memory read) and subsequent rewrite or copy these data from mobile carrier information in computers for secondary treatment, this technical result is achieved due to the fact that addition is copied or overwritten additional data from mobile carrier information in the storage device or in a memory of microprocessor computer (microcontroller) on the hoisting machine or computer. These additional data are obtained, in particular, by assessing the technical condition (diagnosis) hoisting machine or by reading data from a previously installed on this lifting machine Registrar settings, write in a mobile data carrier and after rewriting in the memory device or in memory of a microprocessor of the computer (microcontroller) identify them as data logger parameters for the previous period of operation of the lifting machine. In addition, these additional data can be obtained during the development of primary processing or transformation of the data about the parameters of lifting machinery or work program of the microprocessor of the transmitter in the protection mode of the lifting machine, and after the rewriting of a mobile carrier information in the storage device or in a memory of microprocessor computer (microcontroller) used in the program for the microprocessor-based transmitter, castnet is as part of this program.

To obtain the desired technical effect these additional data can be recorded in a mobile data carrier as an identifier or individual immutable room and used for joint processing at a predetermined and memorized algorithm with a specially designed key (code) for authentication handshake toiletries mobile media to those permitted to work with the Registrar. On a mobile data carrier can also be recorded biometric data of the operator, such as his fingerprints, and the electronic unit can read these fingerprints, with subsequent confirmation of the right of access of the operator to work with the Registrar of parameters.

In addition, this technical result is achieved due to the fact that when rewriting data in a mobile data carrier (instrument reading) with additional controller, built-in mobile media, additionally data encryption, such as the recommendations of the SDMI (Secure Digital Music Initiative). For this purpose, in particular, in a mobile data carrier is additionally recorded (added) authentication code (message authentication code), which is at a predetermined algorithm is developed from zapisywania using the secret code (key), previously entered into the microprocessor computer (microcontroller) or in the computer, and reading stored in the mobile storage medium additional data is read authentication code, then by their joint processing at a predetermined algorithm using the secret code (key) reveals the fact of change stored in the mobile storage medium of the data and in the presence of such a fact formed a message.

Obtaining the necessary technical result in the proposed method is also achieved due to the fact that when the primary or secondary processing of the data about the parameters of hoisting machines additionally verify their validity, as well as the formation of a warning signal in the absence of this certainty. This check is carried out, in particular, by comparing the quantitative value of the at least one parameter with a pre-installed and stored minimum or maximum value for this parameter, by detecting the presence of the increment of time for each subsequent record in relation to the previous or by comparing the values of the individual operating parameters and identifying inconsistencies in the various operating modes of the lifting machine. And specified the neck is of inconsistencies can be carried out, in particular, by defining the operating parameters whose values must be changed in accordance with the established mode of operation of the lifting machine, and further identifying at least one working parameter whose values remain constant (unchanged).

In the recording device (recorder) settings lifting machine that contains an electronic unit that includes a microprocessor computer (microcontroller) and the connected storage device (memory block), and is configured to connect to mobile media (meter reading), which contains non-volatile memory, the specified technical result is achieved due to the fact that the electronic unit is read (copy or overwrite) data from mobile carrier information in the storage device or in a memory of microprocessor computer (microcontroller). The parameters of the storage device of the electronic unit, in particular its information capacity, are installed with the possibility of saving data about the parameters of the previous work of hoisting machines and microprocessor computer (microcontroller) is the ability to change the program of his work in accordance with the additional data, the backgrounds in his memory or storage device.

To obtain the necessary technical of the mobile data carrier can be an identifier - individual immutable number, and microprocessor-based computer (microcontroller) can be performed with the possibility of entering into it, for example by the operator, the registration key (code), as well as the ability to decode and subsequent comparison of this key (code) with the ID of the mobile media and, in case of a mismatch, blocking, overwriting the data from the storage device in a mobile data carrier. Similarly, to prevent unauthorized access to the data recorder, mobile media may be configured to store biometric information such as fingerprints, and electronic unit - capable of reading biometric information (biometric characteristics), such as a fingerprint of the operator.

This technical result is also due to the fact that mobile data carrier contains the controller and the connected block Flash memory and, if necessary, a mechanical switch write protection. The controller of the mobile media apparatus and coordination of the electronic unit is made with the possibility of sharing in what armacia lines with standard SPI Protocol, USB, CAN, LIN, RS-232, RS-485, I2C or wireless information exchange standard Protocol Bluetooth, Wi-Fi or IEEE 802.11), ZigBee or IRDA. In addition, the controller of the mobile media device may be configured to implement the functions of cryptographic protection of information, in particular on WEP 64/128-bit Wired Equivalent Privacy) or on the recommendations of the SDMI (Secure Digital Music Initiative).

Because of those distinctive features of the proposed technical solution is the ability to reprogram how algorithms work of the Registrar and algorithms security hoisting machine can write to the data logger on the previous period of operation of the lifting machine, the effective protection of the accumulated information from accidental or intentional distortion, and it also prevents access for reading out and processing the data logger settings, individuals who do not have such a right. Therefore, these characteristics are in direct causal relationship with achievable technical result.

Earlier in Registrar settings of load-lifting machines mobile media reader telemetry data, the copyist "black box", the readout device and the like) are only used for reading or transferring the information from installed on lifting the car storage device (memory Registrar settings) on the computer for secondary treatment. The reverse transfer any information located on the lifting machine memory to the Registrar or in the memory of the microcontroller using mobile media, has not been previously used. Accordingly, the unknown functions reprogramming Registrar settings or the safety device, in which it is included with this mobile media.

Unknown application in the mobile media Registrar settings of any protection from intentional or unintentional alteration of the information and the implementation of access restrictions to work with Registrar of persons who do not have such rights.

From other fields of technology known protection (encoding) information in a mobile media. However, it is used for other purposes, in particular for the protection of programs, music, videos, etc. from unauthorized copying, i.e. for copyright protection. Known also special mobile media - keys used in the systems access restrictions. However, they are not intended to transfer any information and, accordingly, may not be used in Registrar settings of load-lifting machines.

In the drawing, as an example, the implementation of the proposed technical solutions, performance is established with representation from the functional diagram of the system security hoisting machine with built-in Registrar settings of its work.

Security system hoisting machine contains the electronic unit 1, sensors 2 parameters hoisting machine, the actuating unit 3 and a mobile data carrier 4, which can be connected alternately or to the electronic unit 1 or to the computer 5. The connection of the mobile data carrier 4 to the computer 5 can be performed directly (if in a mobile storage medium and the computer uses the same interface - USB, RS-232, IRDA, Bluetooth etc) or via an additional device read/write 6 (if a mobile data carrier has an interface, such as SPI, SD, etc. that does not coincide with a computer interface).

To restrict access of unauthorized persons to work with the Registrar settings or to work with the security system of the lifting machine, the security system may further comprise a unit operator identification 7 connected to the electronic unit 1 or included in its composition.

The electronic unit 1, is designed as a structurally complete unit or divided into several separate blocks, contains a microprocessor-based computer (microcontroller) 8 and the connected storage device 9 controls 10, the LEDs 11, the real-time clock 12 and the device input/output information 13.

When this storage device can be performed on the Snov chip Flash memory for example series AT, controls 10 - in the form of a set of buttons-keys, indicators 11 - in the form of a set of LEDs and a character LCD indicators and real-time clock is based on a specialized chip with self-contained power source, such as a lithium battery.

Connection of 2 sensors to the microprocessor in the transmitter 8 is performed using a matching device is made, in particular in the form of multi-channel analog-to-digital Converter or device input/output information 13. In the latter case, customers may use separate wires to connect these sensors, and the multiplex communication line using, for example, CAN or LIN interface. Accordingly, the design features of the device input/output information 13 are determined by execution of the output of the sensor circuit 2.

Sensors operating parameters 2 in the General case include sensors weight of lifted load (force or pressure), elevation (tilt) and the length of the boom, the angle of rotation of the hoisting machine (azimuth), wind speed, maximum lift hauling, proximity to transmission lines and other sensors, the installation of which is determined by the specific design of hoisting machine, on which the system is installed safely the property.

Executive unit 3 can be made in the form of a set of electromagnetic power relay or protected power electronic switches connected to the electrohydraulic valves or valves of the control system of the lifting machine.

Mobile data carrier 4 includes non-volatile Flash memory 14 connected to the controller 15. This controller can connect identifier (permanent or one-time programmable storage device) 16, and to prevent unintended damage to information mechanical switch 17 write protection.

The controller 15 of the mobile storage device 4 is performed by any of the known schemes, in order to exchange information with the drive in accordance with standard protocols and specifications SPI, USB, CAN, LIN, RS-232, RS-485, I2C, Bluetooth, Wi-Fi (IEEE 802.11), ZigBee or IRDA. Accordingly, a similar design and has a device input/output information 13 (connect mobile media 4).

Additionally, the controller 15 of the mobile information storage 4, and a device input/output information 13 (connect mobile media 4) can be made with the possibility of a hardware or software encryption and decryption of data, such as SDMI (Secure Digital Music Initiative).

To enable use as a reader/writer 6 standard device for converting the interface of the mobile data carrier 4 in the computer interface, for example USB, it is advisable to use standard media 4. As such a carrier can be used Flash card, in particular a standard Secure Digital Card (SD), Smart Media-ID(SM), Content Protection Secure MMC (CP-SMMC), Memory Stick Magic Gate (MS MG), Secure Compact Flash, or memory JMTek USB Flash Drive.

The unit operator identification 7 (if it exists in the security system) may be implemented, in particular in the form of a fingerprint reader, for example on a chip ATV Atmel.

Explain the essence of the proposed method on the example of the security hoisting machine with built-in Registrar settings.

Before you begin lifting machine in the memory of the microprocessor of the computer 8 or the storage device 9 in advance (prior to the operation of loading the machine) recorded magnitude of loads that are valid for different positions of its arrows or hauling. These values are generally determined, by calculation when designing lifting machinery and presented in the form of its cargo characteristics.

Additionally, the operator using controls 10 is located is connected to the electronic unit 1, provides input parameters that define the modes of operation of hoisting machines - position retractable supports, the degree of hoist winch part of the polyspast, availability, length, and angle of inclination of the jib etc. Similarly the operator enters the parameters of the coordinate protection, define the valid area of the lifting provisions (boom) equipment. Entered by the operator parameters are also saved in the storage device 9 or in memory of a microprocessor of the computer (microcontroller) 8.

During operation of the hoisting machine operator acts on the control levers, for example, hydraulic valves separate hydraulic drive mechanisms of the machine, ensuring the execution of lifting operations lifting and lowering the boom, raising and lowering the cargo winch, rotation of the platform lifting machines etc.

This microprocessor-based transmitter 8 operates according to the program stored in its built-in program memory or storage device 9, and through module I/o information 13 communicates with sensors 2 total multiplex communication line or on separate wires. After receiving information from sensors 2 microprocessor, the computer 8 determines the actual values of the operating parameters of the load-lifting machines - current load and the actual the civil status of her lifting (boom) equipment. Then microprocessor transmitter 8 compares the current position of the boom or lifting body with threshold levels set by the operator with the introduction of the parameters of the coordinate protection, as well as comparing the current load with the stored allowable load for the current spatial position of the boom or lifting body. Then depending on the results of this comparison, i.e. when approaching the arrows to the boundaries of the permitted area of operation on the coordinate protection or in case of exceeding the maximum permissible load, microprocessor-based transmitter 8 generates warning signals for indicators 11, and the switch-off signal currently running actuator lifting machine, which through module I/o information 13 act on the actuating block 3, which removes the control signal from the corresponding electro-hydraulic valve, blocking the movement of the lifting machine. Thanks this is the coordinate protection and protection of the hoisting machine from overload.

Simultaneously, microprocessor-based transmitter 8, working on the program developed, in particular, when designing Registrar settings or security and pre-recorded in his memory, produces particolored and converting received from the sensors 2 information to prepare the necessary operational data about lifting machine for recording in the storage device 9 (in memory of the Registrar). These include, in particular, information about the load on the lifting body, the coordinates of the cargo relative to the hoisting machine, on the management of the impacts of the operator about the condition and performance of components and mechanisms for lifting the machine, about the response of restrictions (blocking) single movement of the lifting machine and other indicators provided technical design task logger settings. In addition, microprocessor-based transmitter 8 similarly defines the basic information about the operation of the hoisting machine or its mechanisms for a certain period of its operation, for example after installation of the Registrar. These include the total operating time of the lifting machine, the total number of cycles, the total mass of lifted loads and other parameters-the parameters stipulated in the technical specification for the design of the logger.

These parameters microprocessor transmitter 8 is recorded in the storage device 9. At the same time it records the date and time of recording of operational parameters, which are determined by the real time clock 12.

If necessary, read the recorded data to the electronic module connects a mobile data carrier 4. Microprocessor computer 8, in accordance with the program it is working, reveals the fact of the connection of the storage medium 4 and installed the standard procedure through the device input/output information 13 and the controller 15 performs the overwrite (copy) data from the storage device 9 in the Flash memory 14. Next, the mobile data carrier 4 is disconnected from the electronic unit 1 directly or via the reader/writer 6 is connected to a computer for transfer (copying) of data from the Flash memory 14 in this computer 5 for secondary treatment. Algorithms for secondary processing determined in advance when developing Registrar settings in advance and stored in the memory of the computer 5.

In the proposed technical solution microprocessor transmitter 8, the device input/output information 13 and the controller 15 is configured to rewrite the data of the Flash memory 14 or ID (permanent storage) 16 in the storage device 9 or the memory of the microprocessor of the transmitter 8.

This gives you the opportunity to make change (correction) of the program for the microprocessor-based transmitter 8 as in preparation of data for recording in the recorder settings, and implementation of microprocessor-based computer security features hoisting machines. For this purpose, we first developed a refined program of the microprocessor of the computer 8 or ragment this program with the help of the computer 5 is written into the Flash memory 14 and then stored into the storage device 9 or the memory of the microprocessor of the transmitter 8, and then used in the program. For a given adjustment of the program can be set modification or registered parameters, adjustment or implementation of additional calculations, including statistical information on the operation of the machine, as well as reconfiguration of the program of the microprocessor of the transmitter 8 to implement security features hoisting machine of another type, such as protection functions overload the machine with another cargo characteristics.

If the logger parameters set on lifting machine, which has previously been operated, the data in the storage device 9 of her previous work, in particular the time will not be accurate. To eliminate this disadvantage of these data is determined by assessing the technical condition (diagnosis) hoisting machine or by swiping them with a previously installed on this lifting machine Registrar settings are recorded in the mobile data carrier 4 computer 5, then overwritten in the storage device 9 or in the memory of microprocessor computer (microcontroller) 8 and identify how the data logger parameters for the previous period of operation of the lifting machine. I.e., data on previous lifting machine to vivalda (added) to current data logger settings. The storage device when this is selected with the necessary supply of information capacity.

Under the current rules, in particular T-399, it is necessary to restrict access to work with the Registrar of individuals who do not have such a right. To implement this mobile data carrier 4 contains the ID of 16, made, in particular, in the form of a persistent storage device recorded therein individual fixed number of mobile media.

To work with the Registrar, the operator, after installation of the mobile data carrier 4 in the electronic unit 1, with controls 10 introduces microprocessor computer (microcontroller) 8 special registration code (key). Microprocessor-based transmitter 8, according to its program, performs the decoding and subsequent comparison of this key (code) with the identifier of the mobile data carrier 4 and, in case of a mismatch, disables (locks) transmit (write) data from the storage device 9 in the mobile data carrier 4.

In another embodiment, access restrictions Registrar of advanced options supplied by the unit operator identification 7 made in the form of his reader biometric characteristics, such as the prints of his fingers. Data about these biomatrices the characteristics of the operator (reference data for later comparison) previously recorded in the Flash memory 14 of the mobile data carrier 4 with a computer 5. After copying this data from the mobile data carrier 4 in the storage device 9 or in the memory of microprocessor computer (microcontroller) 8 and the read biometric characteristics of the operator using the unit operator identification 7, for example upon request generated by the microprocessor-based transmitter 8 indicators 11 after installation of the electronic unit 1 media 4, microprocessor-based computer (microcontroller) 8 compares the actual biometric characteristics of the operator with the reference and, if significant discrepancies, prohibit communication with a mobile data carrier 4 and form a corresponding information message on indicators 11.

Similarly implemented by restricting access to secondary processing information Registrar settings on a personal computer 5. When this code is the access key to be entered by the operator from the computer keyboard or computer additionally equipped with a fingerprint reader his fingers.

In organizational terms, the operator, after training with the Registrar of parameters, together with a corresponding identity receives the data carrier 4, for example in the form of a card, Secure Digital Card (SD) or drive JMTek USB Flash Drive. This media 4 recorded his biometric characteristics (the ring finger), and (or) the cipher-ID. The operator additionally reported code-key to be entered in the electronic unit 1 or in the computer 5.

To read the data logger settings or, if necessary, reprogram microprocessor-based transmitter 8, the operator inserts the storage medium 4 in the slot of the electronic unit 1, enters their code-key or their biometric characteristics (in particular, touches a finger to the fingerprint - identification block operator 7) and then gets the right to perform all necessary operations with the data.

To exclude the possibility of forgery (changes) data logger settings, for example to hide the actual cause of the accident hoisting machine while copying or overwriting of data from the storage device 9 into the mobile media device (reading device) 4, and a subsequent rewrite or copy these data from the mobile data carrier 4 in the computer 5 for secondary treatment may additionally be applied to the encryption of this data.

The encryption algorithm can be implemented using a special controller 15, a built-in mobile data carrier 4, for example, on the recommendations of SDMI (Secure Digital Music Initiative). In particular, when writing data in the Flash memory 14 of the mobile data carrier 4 it is additionally recorded (to ablaut) authentication code (message authentication code), which at a predetermined algorithm produced from the recorded data using the secret code (key), previously entered into a microprocessor-based computer (microcontroller) 8 or in the computer 5, and reading stored in the mobile data carrier 4 advanced data read authentication code, then by joint processing of data and kiestinki at a predetermined algorithm using the secret code (key), reveal the fact of change stored in the mobile data carrier 4 data and, if any such fact, form a message on indicators 11 or on the monitor screen of the computer 5.

With proper execution of the controller 15 of the mobile data carrier 4 in the proposed technical solution is the implementation of the cryptographic functions of the data protection Registrar settings for WEP 64/128-bit Wired Equivalent Privacy). The mechanism of this protection is based on the well-known public key algorithm, as described in the standard for wireless LANs.

To improve the reliability of the data logger parameters in the proposed technical solution in the primary or secondary processing of these data is their additional verification with the corresponding formation of a warning signal to the indicator 1 or the PC monitor 5.

This check is performed by microprocessor computer 8 or the computer 5, in particular, by comparing the values of the parameters of operation of loading the machine with a pre-installed and stored (in storage device 9 or the memory of the computer 5) the minimum or maximum boundary values for each parameter. If, for example, the design of the telescopic boom crane is such that its length is in the range from 7 to 20 meters, it is obvious that the lengths of the arrows, received from the sensors 2 and recorded in the Registrar of parameters cannot exceed the specified boundary values. Therefore, if the output values of any parameter exceeding the limit values, the microprocessor computer 8 or the computer 5 identifies these values as unreliable, and they are not subject to recording in the storage device 9, and may not be used in secondary processing (decryption) of the data logger settings on the computer 5.

Additional validation data logger parameters can be implemented by detecting the presence of the increments of time for each subsequent record in relation to the previous one. In this test microprocessor computer 8 or the computer 5 control that the date and time of each subsequent record is greater than the previous one, i.e. that this difference in time is Yeni positive. This check gives you a certain validation real-time clock 12, and the correct operation of microprocessor-based transmitter 8 when performing records the time and date in the storage device 9.

Effective verification of recorded data in Registrar settings (in the storage device 9 or the validity of the results overwrite them in the computer 5 is implemented by mapping between the values of individual parameters and identifying inconsistencies in the various operating modes of the lifting machine. For example, when designing lifting machines are defined and remembered the zone of possible values of each operating parameter of the lifting machine in different modes of operation. These zones can be stored in memory storage device 9 or the memory of a computer 5 as functions or multidimensional tables.

Microprocessor computer 8 or the computer 5, after receiving data from the sensors 2 or reading information from storage media 4, compares the actual values of these data with the zone of possible values and, in the case of the output current or the read out values of any desktop parameter abroad memorized zone, generates a signal on inaccurate values for this parameter. For example, moving a loaded lifting kanagroos, close to the maximum capacity of the crane, on the big departure is impossible in principle. So if in Registrar settings for some reason received such data, the microprocessor computer 8 or the computer 5 in this way establishes their unreliability.

In the particular case, to simplify the algorithms validation data logger settings, instead of control of finding the values of any desktop parameter in the zone of acceptable values, the microprocessor computer 8 or the computer 5 can control only the changes of this parameter in the established mode of operation of the lifting machine. If, for example, to increase the sensor readings of the boom angle is established that the rise of the arrows, and the readings of the load cell or pressure sensor in the hydraulic cylinder of lifting) are not changed, the microprocessor computer 8 or the computer 5 identifies these values as false.

The invention provides effective protection and validation data logger settings, gives the ability to reprogram the security system of hoisting machines with built-in Registrar settings, enables recording of the Registrar of the previous operation of the machine, and to restrict access to the work with registration is by ATOR persons no such right.
