APPARATUS FOR CENTRALISED AUTOMATIC BLOCK SIGNALLING WITH JOINTLESS VOICE-FREQUENCY RAIL CIRCUITS Russian patent published in 2021 - IPC B61L23/16 

FIELD: signalling.

SUBSTANCE: invention relates to means of signalling, centralisation and blocking on railway transport for interval train traffic control between stations. The apparatus comprises a unit (1) of voice-frequency rail circuit signal generators, a unit (4) of voice-frequency rail circuit signal receivers, a unit (5) for monitoring consecutive occupation of the rail circuits of the block section, a unit (6) for monitoring consecutive release of the rail circuits of the block section, a unit (7) of blocking relays and a unit (8) of signalling relays, a unit (9) for selecting encoding signals, a unit (10) for forming encoding signals, a unit (11) for activating code signals, a long-distance communication transceiver (12), a unit (13) for coordinate unblocking and reconfiguration, a unit (17) for centralised monitoring of the integrity of trains, a computer (18) of the automated workplace of the dispatcher. The transceiver (12) is therein in communication with the radio message generation unit (15) installed in the front of the train (14) via a long-distance radio channel, wherein a satellite navigation unit (16) for determining the current coordinate when the train is moving along the block sections of the rail line with blocked or falsely occupied rail circuits is connected to said unit.

EFFECT: scope of application of the apparatus is expanded due to the possibility of working with trains, the structure whereof does not exclude uncoupling of the train cars.
