AUTO-LOCKING DEVICE WITH TONE TRACK CIRCUITS AND CENTRALIZED EQUIPMENT PLACEMENT Russian patent published in 2022 - IPC B61L23/16 

FIELD: train traffic interval control.

SUBSTANCE: invention relates to means for interval control of train traffic on hauls. The device includes track through traffic lights that enclose block sections, rail circuits of protective sections of track through traffic lights and track chains of block sections, a track circuit control unit, including generators connected to the beginnings of track circuits, and receivers connected to the ends of track circuits, transmission units to the locomotive of numerical code signals, each of which is connected to the beginning of the rail circuit of the protective section of the corresponding traffic light connected to the corresponding block of signal indications, coding switching blocks, each of which, with its first and second outputs, is connected respectively to the input of the corresponding block for transmitting numerical code signals to the locomotive and the input of the corresponding block of signal indications , the start input of each coding enable block is connected to the corresponding output of the permission to send the QOL code of the track circuit control unit, the configuration input of which is connected to the output of the controller connected via a communication channel to the dispatching control center. Moreover, on the stretch opposite the middle part of each track circuit, an axle counting point with autonomous power supply is installed, equipped with a low-power radio channel transceiver for communication with a mobile transceiver installed on the locomotive connected to the internal digital wired communication interface, to which the locomotive safety device and the long-range radio communication transceiver are connected, while in the dispatching control center there is a block for fixing the passage of trains in the full complement of axle counting points, the data port of which is connected to the first data port of the computer of the train dispatcher's workstation, the second data port of which is connected to data port of a stationary transceiver for long-range radio communications of the dispatching control center.

EFFECT: increased throughput of the haul.
