FIELD: machine building.
SUBSTANCE: invention relates to railway automation and telemechanics. Device comprises a stationary device, a channel which consists of a central processing unit, units: input/output, memory, information input, decision, analysis, display, and onboard device, a channel which consists of a microcontroller, following units: memory, galvanic isolation, connector, CAN bus and locomotive safety device. Stationary device is two-channel, in addition, each channel includes an encryption unit, a communication unit, cryptographic gateway, as well as data input unit. On-board device is two-channel, in addition, each channel includes decoding unit, a transceiver, automatic train operation system, a memory unit, made up of two independent modules, a unit for inter-channel galvanic isolation, one of microcontrollers of on-board device and one of central processing unit of stationary device are connected by a communication channel via appropriate radio channel modules.
EFFECT: higher fault tolerance of device.
