The complex for checking on-board systems of an unmanned aerial vehicle operates as follows.

By means of the remote control 10, the following operations are performed:

manual switching on of the equipment by the operator using the buttons of the control panel 87, after which the keyboard 81, the computer display 80 and the documenting device 83 provide the possibility of using the operating system’s internal tools for effective interaction with the operator in each of the complex operation modes;

initial testing of the central computer 80 and computer 44, 53, 67 of devices 5, b and 7;

initial loading of basic and technological software from external drive 82 (in the future, an external drive can be used to adjust the software and software in case of changes during the operation of the complex).

The equipment of the control panel 10 provides control of the control process, coordination of the operation of all equipment of the complex, a visual display of the control process, its intermediate and windows Z (W /.

- 13 useful results, documentation of control results, emergency power outage, work as an expert system.

Software and software is located on flash disks of computers 44, 53 67. Coordination of the devices 5, 6 for controlling the control system and electrical equipment and device 7 for self-monitoring is provided by the central computer 80, which is connected by an interface highway 14 to a hub 9 of the local network, connected “1 via interface lines 11, 12, 13 and adapters 46, 55, 68, respectively, with computers 44, 53 and 67. Continuous monitoring of the state of the computing systems of devices 5, 6 and 7 is carried out by monitoring devices 45, 54 and 69, connected on the basis of RS-485 Interface with the central computer 80.

The structure of the devices that ensure during the UAV test 2 the issuance of control commands to the relay devices of the on-board systems and the reception of response signals from the actuators is identical and is represented by relay transmitters 41, 50 and 65 of the commands and galvanic isolation devices 43, 52 and 66, which interact through the devices 42, 51 and 64 of discrete input-output with computers 44, 53 and 67.

During the test, the operator sets one of the main modes of operation with the buttons of the control panel 87: regular monitoring of the onboard UAV systems or self-monitoring of the complex. Each mode can be performed in full or with restrictions. After selecting the mode from the keyboard 81, the initial data corresponding to the characteristics of the equipment under test are entered.

When operating in the standard control mode, there is no control signal at the control input of the switching device 3, and the switches 29, 30 31 are set to the first position in which:

the first input of the switch 29 of the control points is connected to its output, providing a connection of the first output of the IDL 2 with the input of the switch 58 of the control points of the device 6 control electrical equipment;

the input of the command switch 30 is connected to its first output, providing a connection of the outputs of the transmitter 41 commands of the device 5

control system control and transmitter 50 commands of the device b control electrical equipment with the first input BILA 2.

the first input of the signal switch 31 is connected to its output, providing a connection to the second output of the UAV 2 with the input of the galvanic isolation device 43 of the control system control device 5 and the input of the galvanic isolation device 52 of the electrical control device b.

In the standard control mode, the UAV’s electrical systems are first checked using the electrical equipment control device. The health check of relay devices of electrical equipment 26 is carried out by issuing control commands, which are generated at the respective outputs of the transmitter 50 of the commands in the form of DC voltages and are transmitted via command switch 30 via cable 21 of the transmitting relay channel to junction device 27, through which they are distributed to the corresponding relay devices of electrical equipment 26. The response signals of the respective actuators through the crossover device 27 via cable 22 of the receiving relay th channel receives a first input signal selector 31, the output of which is transmitted to respective inputs of unit 52 electrical isolation of electrical control devices used.

Using the device 59 for measuring resistances and potentials, the presence or absence of connections between the control points of the electrical equipment, as well as the potential values of the control points are monitored. The choice of a combination of the tested points for monitoring the resistances and measuring the potentials is made by a control signal supplied to the control input of the switch 58 of the control points from the second output of the discrete input-output device 51. Then, in the converter 60, the resistance values between the selected test points are converted to a DC voltage, which, if there is a corresponding control signal at the input of the switch 62, is fed to the information input of the analog signal analyzer 63. The selected control points at which potentials are to be measured are connected to the block of normalizers 61, which provide galvanic isolation of the circuits, and from it through the switch 62 they are connected to the analyzer 63. The analyzer 63 is fast-acting

a meter based on analog-to-digital converters and input signal comparators. In the case of the appearance of unacceptably high potentials at controlled points, a reaction of the analyzer comparators 63 occurs, which interrupts the computer processor 53 and, as a result, removes power from the on-board devices.

The next stage of staff control is to check the health of the control system 24, which is performed by the control device 5 of the control system. In this case, the check of the relay devices of the control system 24 is carried out similarly to the check of the relay devices of the electrical equipment 26 using the transmitter 41 connected via the command switch 30 to the cable 21 of the transmitting relay channel for transmitting commands, and the galvanic isolation device 43 connected via the switch 31 to receive response signals signals with cable 22 of the receiving relay channel.

Verification of on-board computing devices is carried out using the adapter 39 of the multiplex and interface line 15 of the multiplex channel of information exchange.

To check the radio devices during the execution of the control task, the reference voltage is supplied to the intermediate frequency amplifiers 34, 36, including the target simulator 4, from the output of the simulator switching unit 38, which is formed as a DC voltage. The simulator 4, receiving the probing signal emitted by the antenna 23 of the radar sighting device and received by the control antenna 1 at the first input of the circulator 32, transmits it to the input of the first frequency converter 33, which is added to the reference frequency signal of the radar sighting device. Further, the signal converted to an intermediate frequency is amplified in the amplifier 34, delayed by the delay line 35, amplified in the amplifier 36 and fed to the input of the second frequency converter 37, performing the inverse of the frequency conversion with respect to the converter 33. Next, the signal corresponding to the simulated target range, through the circulator 32 is supplied to the control antenna 1 and is radiated into the space side of the antenna 23 of the radar sight.

If necessary, determined by the initial control program, the control device 5 of the control system also performs

Ш /Я, 91 -16 analysis of telemetry signals received at the input of multiplexer 40 via cable 19 of the relay channel of communication with the telemetry device 25.

Self-monitoring of the complex can be performed in two modes - operational, providing verification of the serviceability of devices and inter-instrument communications regardless of the connection to the on-board equipment, and self-monitoring with coverage of external communications.

The online mode of self-monitoring is carried out by the device 7 of self-control, which at the beginning of the test by the control command from the second output of the discrete input-output device 64, supplied to the control inputs of the switches 29, 30, 31, sets them to the second position. The output of the switch 29 of the control points is switched with its second input connected to the output of the crossover device 74, the output of the switch 31 of the signals is switched with its second input connected to the output of the transmitter 65 teams, and the input of the switch 30 teams is switched with its second output connected to the input of the device 66 galvanic isolation.

During self-control, the device 7, by analogy with the on-board equipment, receives control commands from the control device 5 of the control system and the electric equipment control device 6 and generates response signals. Simulation of possible situations that arise between the control points of electrical equipment is carried out using a simulator of 72 potentials and a simulator of 73 messages.

When self-monitoring with external communications coverage, the cable lines 20, 21 and 22 are disconnected from the corresponding BSh1A connectors 2. Cable 20 connects the first input to the fifth input of device 3, cable 21 connects its first and fourth outputs, and cable 22 connects the second and fourth inputs, as shown in broken lines in FIG. 1 and FIG. 3. In the future, the verification is performed in the same way as in the online mode of self-control. The difference lies in the absence of a control signal at the control inputs of the switches, due to which they are in their first state, as in the regular monitoring of onboard UAV systems 2.

If necessary, check also the computing devices of the control system 24, which are exchanged via the multiplex channel, line 15 is disconnected from the output of the system 24

Utli3 S - 17 control and connect to the input-output adapter 70 of the multiplex channel of the device 7 self-monitoring, connecting it to the adapter E9 of the multiplex channel of the device 5 control of the control system. This creates the possibility of mutual functioning of the computer 44 and 67 to test the multiplex communication channel with the control system.

Thus, the proposed complex for testing onboard UAV systems has wide functionality and increased reliability of test results due to the control coverage of radio systems, computer systems and electrical equipment, an increase in the number of monitored parameters and automation of the test process.

The industrial applicability of the utility model is determined by the fact that the proposed complex can be made in accordance with the above description and drawings on the basis of well-known components and technological equipment and used for complex verification of onboard UAV systems.
