TRAFFIC LIGHTS CONTROL DEVICE Russian patent published in 2015 - IPC B61L29/22 

FIELD: electricity.

SUBSTANCE: device comprises the station control unit and wayside control units. The station control unit consists of the central double-channel signal processor, which first and second inputs are connected to the respective CAN-interfaces, and its first and second outputs are connected to the first and second amplifiers respectively, output of the first channel of the central double-channel signal processor is connected to the first input of signals summator/divider, while the second input of the latter is connected to output of the first amplifier, output of the second channel of the central double-channel signal processor is connected to the first input of the second signals summator/divider and the second input of the latter is connected to output of the second control signal amplifier, outputs of the first and second signals summators/dividers are linked to communication lines. Each sideway control unit consists of signals summator/divider connected to the traffic light control/monitoring unit, which outputs are connected to the unit for control of traffic light lamps, output of the signals summator/divider is connected to the control input of the power supply unit coupled to the unit for control of traffic light lamps.

EFFECT: expanding functionality of the device, improving its interference resistance, reducing power losses in the communications line, improving reliability and safety of the train traffic.
