DEVICE FOR DATA EXCHANGE OVER RADIO COMMUNICATION CHANNELS Russian patent published in 2019 - IPC B61L25/00 

FIELD: railway automatics.

SUBSTANCE: invention relates to railway automation, telemechanics and communication, can be used on locomotives of trains both separately and as part of multilevel interval control systems for data exchange over radio communication channels. Device comprises two communication channels, each of which consists of microprocessor module, connected to memory unit and connected through galvanic isolation to CAN transceiver, connected to CAN bus, to which a locomotive safety system and an automatic driving system are connected, further includes a network switch, a cryptographic information security module, a radio modem, a GSM radio channel module and a Wi-Fi radio channel module. At that, microprocessor modules of communication channels through network switch are connected to information cryptographic protection module, to which radio modem is connected, a GSM radio channel module and a Wi-Fi radio channel module, a module and an information display module are connected and connected to the GPS microprocessor module in one of the communication channels.

EFFECT: enabling increase in the security level and ensuring the integrity of the transmitted critical information when the coverage area of the radio channel is increased.
