DEVICE FOR CENTRALIZED AUTOMATIC BLOCKING WITH CONTINUOUS RAIL CIRCUITS OF TONE FREQUENCY Russian patent published in 2024 - IPC B61L23/16 

FIELD: rail vehicles.

SUBSTANCE: invention relates to means of centralized automatic blocking with continuous rail circuits of tone frequency for interval control of movement of trains both on hauls and at stations, at routes with switched on mode of automatic passage of trains. Device contains in each semi-set of automatic blocking signal box equipment unit (1) of signal generators of rail circuits, connected through transmitting cores of cable line (2) to transmitting ends of rail circuits of rail line (3) of its block section, and rail circuit signal receivers unit (4), block section rail circuit successive occupation control unit (5), unit (6) for monitoring successive release of rail circuits of the block section, blocking relay unit (7), signal relay unit (8), coding signals selection unit (9), coding signal generator unit (10), code signal switching unit (11), long-range radio communication transceiver (12) with connected to it coordinate unlocking and reconfiguration unit (13), unit (15) for generating radio messages installed in the head part of electric train (14), to which satellite navigation unit (16) is connected, providing determination of current coordinate during movement of electric train along block sections of rail line with blocked or falsely occupied track circuits. Device is also equipped with unit (17) for digital simulation of the correct occupation of rail circuits and unit (18) for generating an inviting signal.

EFFECT: wider field of application of the device is achieved.
