FIELD: railway transport.
SUBSTANCE: invention relates to automatic identification of rail vehicles passing over double-track sections of railways. Proposed system contains code on-board sensors and reading centers. Reading centers consist of four antenna connected through antenna switch to circulator. Output of circulator is connected with input of receiver. Second input and output of receiver are connected with first output and first input of control unit. Second output and second input of control unit are connected with first input and first output of transmitter. Second output of transmitter is connected with input of circulator. Bi-directional output of control unit is connected with first bi-directional output of modem. Second bi-directional output is connected with data network.
EFFECT: improved reliability of read out of information.
