The locomotive device 1 begins to work immediately after turning on the power source 6. The signals from the radio modem 15 of the stationary device 14 are transmitted through the communication channel through the antenna 11 and the duplex filter 10 to the radio modem 5, which exchanges information between the locomotive device 1 and the stationary device 14. Further, the signals are sent to unit 4 of the electronics in accordance with the interaction algorithm. The signals from the antenna 13 enter the block 12 packet communication (BPS), designed to transmit data about the location and motion parameters, and from it the data already goes to the block 4 electronics, designed to process information from the sensors of the path and speed, the satellite navigation receiver, signals from receiving coils, vigilance control systems, signal from button 3 “Alarm” Unit 4 analyzes the received information and generates control actions on the electro-pneumatic valve 9 (EPC), the prefix of the crane driver 8 (PCM) and the chain of rods , Antenna 2 GPS / GLONASS, a radio modem 5, and transmits data for display on the display unit 7.

The signals from the GPS / GLONASS antenna 2 are fed to the navigation receiver (not shown in the figure), which is part of the electronics unit 4, which generates data on the location of the device (latitude, longitude).
