The turret machine gun remote control device consists of 5 qrd1114 optocouplers (1), which read the rotation of the turret machine gun mount, 5 qrd1114 optocouplers (2), read the lifting of the cradle with machine guns, a controller on an Arduino MEGA PRO programmable board (3), an L298n motor driver (4 ), an electric motor for turning a turret machine gun (5), an electric motor for lifting a cradle with machine guns (6), an electric trigger relay (7), a relay for closing an electric trigger for a Kalashnikov tank machine gun (8), a relay for closing an electric trigger for a large-caliber Vladimirov tank machine gun (9), a turn-on relay a video surveillance camera installed on the sight (10), a relay for switching on a night sight (11), a remote control module NRF24L01 (12), on-board power supply to the engine driver (from the network of a tower machine gun) (13) (Fig. 1); disk with Gray code (3) installed on the driving gear (4), the electric motor (1), the electric motor reducer (2), the driven gear (5) (Fig. 3); disk with Gray code (1) installed on the intermediate gear (5), the drive gear (2), the electric motor reducer (3), the electric motor (4), the driven gear (6) (Fig. 4), as well as the software.

The device works as follows.

When you turn on the device, the program starts. The program starts the program code and within 10 seconds the device is calibrated (we scroll the gear to the black sector and after 5 seconds we scroll the gear to the white sector, the device recognizes the gray value for the given time period). Further, through the remote control, a signal is sent to the turret machine gun (2 modes of operation are indicated in the program code: 1st mode - through the buttons of the remote control, for precise guidance of the turret machine gun installation; 2nd mode - control of the joystick of the remote control controls, for rapid rotation of the turret machine gun). At the same time, optocouplers read the angle through which the tool should turn or rise (PKT and KPVT).

To control the activation of electric triggers, a video surveillance camera installed on the sight (night sight), as well as closing the PKT electric trigger and KPVT electric trigger, remotely controlled relays were added, connected to digital pins D22, D10, D11, D12 and D13.

The optocouplers are connected through the optocoupler output circuits to the analog pins of the arduino. 5 optocouplers are used to read the angles of rotation of the tool and 5 optocouplers to lift it, the nearest optocoupler is connected to the center of rotation of the arduino port A0, and the farthest to A9.

The motor driver uses pins D2 through D7 to rotate the turret machine gun at different speeds, depending on the mode selection on the remote control. To rotate the tower machine gun hourly, the maximum voltage (HIGH or 1) is applied to the D2 pin, and the minimum voltage (LOW or 0) to the D4 pin, for counterclockwise rotation we change the voltage supply values to D2 and D4. To control the speed of rotation, a logical unit is supplied to pin D3. To raise the implement, the maximum voltage (HIGH or 1) is applied to the D5 pin, and the minimum voltage (LOW or 0) to the D6 pin; to lower the implement, we change the voltage supply value to D5 and D6. To control the lifting speed of the implement, a logical unit is supplied to pin D7.

To check the operation of the device, a sketch for arduino has been developed. In order for the device to determine whether it is reading black or white, it is necessary to calculate the value that is called gray. For this, a special calibration function has been developed, which reads white values from all sensors at 5 second intervals, and then from all black sensors and after that the arithmetic mean of white and black for each sensor is calculated, which is considered gray. For optocouplers, the (Scan) function is written in order to obtain the Gray code. Data is received by comparison with gray.

The next step is to write the String GreyToBin (Strings) function that translates the Gray code into binary code. For this, modulus addition of 2 (x% 2) is used to obtain the bits of the binary code. Next, you need to convert from binary representation to decimal code using the usual algorithm through the power of 2.

The algorithm for calculating the movement of the gun horizontally or vertically consists in sequentially fixing two values of the Scan () function and obtaining the numbers of the initial and final sectors. The difference in sector numbers, multiplied by the angle of one sector to another, is the angle of rotation. The value of the sector angle is determined by the number of circles on the disk, i.e. the number of bits used in the Gray code.

The use of this technical solution will make it possible to more accurately aim the gun and hit targets with a minimum number of shots (the transition from one sector to another is 0.03 i25 degrees of rotation of the turret machine gun, which is an error of 54 cm at a distance of 1000 meters), as well as remote control of the turret machine gun installation at a distance of up to 2000 meters, since the device has a radio module.
