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

FIELD: transport traffic control systems.

SUBSTANCE: invention relates to signaling, centralization and interlocking devices for interval control of train movement on hauls. Device comprises a unit of signals of track circuits of tone frequency, unit of receivers of signals of track circuits of tone frequency, unit for sequential occupancy of rail circuits of block-section, unit for monitoring sequential release of track circuits of block-section, unit of blocking relays, unit of signal relays and unit for inclusion of coding of rail circuits, a testing unit, a low-frequency rail circuit signal generator, a low-frequency rail circuit signal receiver, a reset and reconfiguration signal generation unit, a route man-machine control circuit, an automated workstation computer for the duty officer / dispatcher of the departure station. At that, the AWS computer is connected to the artificial route cutting control element, with a unit for receiving signals from track devices controlling passage of the last cars of trains and with a unit for receiving signals from on-board systems for monitoring the full composition of trains.

EFFECT: higher reliability and speed of checking free and health of block sections of hauls at artificial processing of short circuit of distillation devices after false closing of equipment of track sections.
