Bidirectional multiplex channel information exchange 14 is a channel that combines the blocks SUOVO.

The information exchange channel 15 serves to interface the units of the SUOVO with avionics 13.

SUOVO works as follows.

SUOVO contains the main, control and backup channels of calculations and transformations, consisting of the main, backup and control blocks of calculations and transforms BPV 1, 5, 6, respectively, and n-blocks of protection and switching BZK 7.

The modules for receiving analog signals 2 included in each BPV, the modules for receiving discrete signals 3 receive parametric information via the information exchange channel 15 from the avionics systems 13 and general helicopter equipment 12. These modules are connected to the processor and input / output module 4, which processes information, formation of control commands and their transmission via a bi-directional multiplex channel of information exchange 14. BPV receives and filters the input supply voltage of the on-board network, forms ue voltage power supply modules, as well as equipment obschevertoletnogo sensors forming and issuing the signal "Serviceability '.

The processor and input / output module 4 is connected to a bi-directional multiplex information exchange channel 14 and is connected to each of the modules of the processor device 10 of the BPC 7.

In the system, the main, control and backup units BPV 1, 5, 6 interact with the mated avionics BREO 13 through the information exchange channel 15.

Each block of n-blocks BZK 7 contains a first control channel 8 and a second control channel 9. Each control channel consists of functionally independent modules of the processor device 10 and m-modules for transmitting power commands 11 to executive devices of general helicopter equipment. In the event of a failure of any module of the processor device of one of the control channels, the power command transmission modules are controlled by a working module of the processor device. In accordance with the requests issued by the processor and input / output modules of 4 BPV units 1, 5, 6, the module of the processor device 10 of the БЗК 7 through m-modules for transmitting power commands 11 issues power control commands to the general helicopter equipment 12, by switching the power input of the blocks of the systems of the general helicopter equipment to the required output of the control command 8 or 9. In accordance with the requests for the status of the built-in control, the OPC transmits the following information to the bi-directional multiplex information exchange channel 14: echo si drove each control command, the value of the current in the switched circuit, the value of the total current of the channel of the block (the total current of all control commands measured at the input of the block), the voltage at the input of the block, signs of failure and disconnection of the output circuits as a result of overcurrent protection and short circuit.

Upon receipt of a command to issue a signal from the BPV, the UPC checks the possibility of issuing this command for the absence of a sign of blocking as a result of the work of the built-in control systems (VSK). If it is possible to issue, a control command is issued.

The control of general helicopter equipment is carried out by the SUOVA by comparing the generated control commands with the information received from the general helicopter systems as a result of its execution and using the “request” commands received from the BREO 13 BSTO (on-board diagnostic system) and initiating the start of the built-in self-monitoring procedure for the systems included to the avionics 13. Information on the results of the control of the SUOVO is transmitted to avionics 13.

All SUOVO units - calculation and conversion units, protection and switching units are equipped with built-in performance monitoring tools that, as a result of comparing calculations and indications in the main and control channels, in case of mismatch, identify the failed channel with a high degree of certainty and switch to using a working backup channel.

SUOVO blocks, consisting of universal functionally independent modules, are developed based on the use of multiprocessor tools that provide high performance and functional division of the tasks being solved - digital signal processing, execution of parametric information control algorithms, execution of control system reconfiguration algorithms in order to minimize the consequences of failure, generating control commands , assessment of their own performance without the use of ground control and testing apparatus cheers.

Thus, in the inventive system implemented three-fold redundancy control of general helicopter equipment. This provides integrated control of general helicopter equipment, high reliability and flight safety, and also leads to lower helicopter operating costs.
