AUTO-LOCKING SYSTEM WITH TONE TRACK CHAINS Russian patent published in 2023 - IPC B61L23/16 

FIELD: railway traffic.

SUBSTANCE: signaling systems, centralization and blocking in railway transport, in particular to devices for interval regulation of train traffic on hauls. The system contains track through traffic lights installed at the boundaries of block sections, rail circuits of block sections, rail circuits of protective sections of track through traffic lights, a track circuit control unit, including signal generators for monitoring track circuits and ALS signals, each of which is connected to the beginning of the track circuit of the respective block section, additional track circuit control signal generators, the output of each of which is connected to the rails of the relay end of the track circuit of the corresponding block section, and receivers of the track line control signals and ALS signals, each of which is connected to the end of the track circuit of the corresponding block section, as well as blocks for transmitting numerical code signals to locomotives, 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, blocks for switching on coding, each of which is connected with its outputs to the inputs of the corresponding transmission block to the locomotive of numerical coded signals and the corresponding block of signal indications, a controller, current receivers of signals for monitoring the track circuit, each of which is connected to the track circuit of the corresponding block section in its middle part, stationary radio transceivers of a low-power radio communication channel, the output of each of which is connected to the input of the corresponding current signal receiver control of the track circuit, on train locomotives, the data ports of the on-board radio transceiver of the long-range radio communication channel and the on-board radio transceiver of the low-power short-range radio communication channel are connected to the internal digital wire communication interface for interaction with the locomotive safety device, in the dispatch control center the data port of the stationary long-range radio communication transceiver of the dispatch control center is connected to to the data port of the automated workplace of the train dispatcher, which includes a software module for fixing the passage of trains in the full composition of sections of track circuits of block sections, while the start input of each coding enable block is connected to the corresponding output of the permission to send the code of the track circuit control unit, the configuration input of which is connected to the controller output, connected to another port of the automated workplace of the train dispatcher, the power supply circuits of the current receiver of the rail line control signal and the track stationary radio transceiver of a low-power radio communication channel are connected to an internal battery power supply.

EFFECT: increased reliability of the auto-locking device in terms of resistance to failures.
