DEVICE FOR TRANSMITTING CONTROL COMMANDS TO THE RAIL CIRCUITS OF A CENTRALIZED AUTOMATIC BLOCK SYSTEM Russian patent published in 2021 - IPC B61L23/16 

FIELD: rail traffic facilities.

SUBSTANCE: invention relates to the means of transmitting control commands to the rail circuits of a centralized automatic block system. The device contains the first CAN communication interface, to which the control unit of the interaction signals of the interval control system and the computer of the automated workplace of the station attendant are connected, the second CAN communication interface, to which the logical reconfiguration unit of rail circuits and the CRL and ALS signal transceiver are connected by means of a signal cable to the rail circuit, the rail circuits on the section between the stations are divided into groups of rail circuits, each of which is connected to the corresponding CRL and ALS signal transceiver, placed with the corresponding block of logical reconfiguration of rail circuits in a separate cabinet of floor equipment, equipped with a power supply unit connected to a two-wire longitudinal power supply line, while in each separate cabinet of floor equipment, the first bidirectional optoelectric converter of communication interfaces is additionally connected to the second CAN communication interface, to which the block of logical reconfiguration of rail circuits and the CRL and ALS signal transceiver are connected, and the first bidirectional optoelectric converter is connected through the first optical interface element to the main fiber-optic digital communication line laid along the railway track, and at the station where the computer of the automated workplace of the station attendant is located, a second bidirectional optoelectric converter of communication interfaces is connected to the first CAN-communication interface, which is connected to the main fiber-optic digital communication line through the second optical interface element.

EFFECT: achieves the simplification of the implementation of the device with the expansion of the scope of application.
