The inventive utility model allows you to effectively maintain a high degree of readiness for the use of a homing system, through the introduction of a group simulator-simulator, which provides real modeling of homing objects in all operating modes.

The objective of the utility model is the ability to constantly verify the functioning of all electrical circuits of the homing object, control the exchange of code information, and solve various options for the use of homing objects.

The utility model allows in all operating modes to simulate real malfunctions of the homing object and get an adequate response to them in an automated control system.

These qualities are achieved due to the structural organization of the simulator, made in the form of a multi-channel device, which combines the n-number of simulators with independent control and automatic control of the health of each channel when it is included in the work. At the same time, the distinctive essence of the utility model is that it implements a relay signal failure simulation unit, a multiplexer, an indication unit, an address decoder, a reset button, and a multiplexer that is connected via a multiplex bus to devices for processing relay and code signals.

The connections in the remaining simulators of the homing 1.1-1n are similar to the considered simulator 1.

The proposed utility model simplifies the hardware and software control of a group simulator, while increasing the reliability of the simulation equipment. A high level of reliability is ensured by automatic test control included in the work

module (channel). An autonomous health check is performed each time the module is turned on or by pressing the reset button 18. The result of the autonomous test is displayed in the display unit 14 on the indicators “Test passed” - “Test failed”. Checks are performed on the fault simulation block 5, electronic keys with relay b, address decoder 15, microcontroller 17, multiplexer 7, multiplex bus 13, transmit and receive code channels 8.

After turning on the power of the module (or pressing the reset button 18), the microcontroller 17 issues commands to the fault simulation unit 5 to sequentially turn on and off the electronic keys from relay 6. Each change in the state of the relay is read by the microcontroller 17 from multiplexer 7, after which the expected and obtained result is compared.

In case of a positive result of checking the operation of the relay, the indicator “Test passed” lights up in the display unit 14, in case of a mismatch of the result - the indicator “Test failed” lights up.

Regardless of the result of checking the relay part of the circuit, the code exchange device is checked 8. The microcontroller 17 writes a 32-bit word into the registers 9 of the output circuit, turns on the receiving circuit of the code channel for reception, and issues a command to issue. After receiving an interrupt from the receiving circuit, the microcontroller reads the received word from the registers 11 of the receiving circuit and compares it with the given one. In the case of complete correspondence of the received word to the given, in the display unit 14 the indicator “1p” lights up. If a discrepancy is detected or if there is no interruption, the 1p indicator remains off.

Consider the training mode, which allows you to prepare operators for work in normal modes. When the control system is turned on in the "Training" mode, the group of inputs / outputs 21 with a simulator is connected and the group of inputs / outputs 20 with the homing object is blocked.

The control system interacts with the simulator through two code and one relay exchange channels. Through the first code channel, information for exhibiting an inertial system, flight task information, and control system parameters is transmitted to the simulator through reception registers 11.

Information on the results of the passage of the regime in the form of one word about the serviceability (malfunction) of the airborne complex is provided through the second code channel from the simulator through registers 9. The control system analyzes the adopted word and, with a positive result, continues to execute the specified mode, with a negative eliminates the homing object simulator from further work. Receiving and issuing information in the code exchange device 8 is carried out with a 32-bit serial code at a frequency of 50 Kbps.

The reliability of the received information is achieved by the following types of control performed in the microcontroller 17:

- control of each word for parity;

- array control by a private checksum;

- control of arrays by the total checksum.

If the control result is negative, the transfer of the array is repeated, but no more than 2 times, after which the simulator of the homing object is excluded from work.

The interaction of the control system with the simulator on the relay channel is carried out in the form of commands received by the relay signal processing device 2:

- turn on the power;

- turn on telemetry equipment;

- control of the airborne complex and engine;

- remove the blocking of working circuits;

- turn on the onboard power supply;

- launch of a homing object.

Relay signals are issued from the simulator through electronic keys and relays 6 to the control system:

- the presence of a homing object;

- about its configuration;

- about the state of blocking of working circuits;

- on the inclusion of an onboard power source;

- about the start of the homing object.

In the "Training" mode, the operator of the control system has the opportunity to simulate various types of malfunctions of the homing object. For this purpose, at the beginning of the mode, information on the form and time of a given malfunction is recorded in the simulator multiplexer.

All commands and signals to the simulator are issued by a DC supply voltage of ± 27 V. All information about the progress of the mode, including information about the violation in interaction with the simulator, is documented in the central instrument of the control system for further analysis.
