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

FIELD: transportation.

SUBSTANCE: invention relates to means of centralized automatic blocking with continuous rail circuits of tone frequency. Device comprises unit 1 of tone frequency track circuits generators connected through the transmitting cores of cable line 2 to the transmitting ends of the track circuits of rail line 3 of its block section, and unit 4 of receivers of signals of track circuits of tone frequency, unit 5 for monitoring sequential occupation of track circuits of block section, block section rail circuits sequential release control unit 6, blocking relays unit 7, signal relay unit 8, coding signals selection unit 9, coding signals generation unit 10, code signals switching unit 11, long-distance radio communication transceiver 12 with connected to it coordinate unlocking and reconfiguration unit 13, unit 14 for monitoring sequential occupation and release of boundary track circuits of a section with a reconfigured falsely occupied track circuit, time delay unit 15 for sequential logical occupation of track circuits of the reconfigured section.

EFFECT: increasing traffic capacity and traffic safety.
