DEVICE FOR CENTRALIZED AUTOMATIC INTERLOCKING WITH WELDED TRACK CIRCUITS OF TONE FREQUENCY Russian patent published in 2019 - IPC B61L23/16 

FIELD: transportation.

SUBSTANCE: invention relates to railway automatics for traffic control. Proposed device comprises semi-hardware of on-board hardware and bead part. Each semi-set of automatic interlocking hardware includes a unit of signal generators of track circuits of tone frequency, transmitting lines of the cable line, signal unit of signals of track circuits of tone frequency, unit for monitoring sequential occupancy of track circuits of block section, unit for monitoring sequential release of track circuits of block section, a blocking relay unit and a signal relay unit, a coding signal selection unit, a coding signal generator unit, a code signal activation unit, a signalling relay unit, a long-range radio communication transceiver, a coordinate unlocking and reconfiguration unit. Side part includes installed in head part of electric train formation unit of radio messages generation, to which satellite navigation unit is connected, which provides determination of current coordinate when electric train moves along block sections of rail line with locked or false rail circuits.

EFFECT: higher throughput capacity and possibility of automatic unlocking of passed section of track, as well as reconfiguration of false occupied track circuit.
