Processing method for bad branch circuit of track circuit

Abstract

The embodiment of the invention discloses a processing method for a bad branch circuit of a track circuit. In the method, if by interlocking, first information of semaphore overwhelming of an inlet circuit initial end of a target section sent by a zone controller is received, and it is determined according to second information that the current target section is not occupied at present, it is determined that the target section is currently in a fault state in which the inlet circuit initial end is poorly connected. After the fault state is identified by the interlocking, third information corresponding to the fault state is sent to the area control, so that an area controller identifies the fault state according to the third information, and according to logic corresponding to the fault state, a train in the target section is controlled. The method is used for identifying the bad branch circuit by the interlocking, and judgment errors on whether the section is occupied by the interlocking are avoided; on the other hand, the area controller identifies the bad branch circuit through the interlocking, and the problem that the downtime occurs when the area controller has the bad branchcircuit, so that a train brakes urgently, affecting the operating efficiency of a line is solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of urban rail transit systems, and in particular to a method for dealing with poor branching of rail circuits. Background technique [0002] In the urban rail transit system, some stations have a large number of tracks. For cost saving or other reasons, the axle counting system is not deployed, but the track circuit is laid. The track circuit is a line composed of rail lines and rail insulation. It is used to automatically and continuously check whether the section of the line (or section) is occupied by rolling stock to ensure driving safety. The track circuit cuts off the electrical circuit through the rails on both sides of the short circuit of the train wheels to reflect that the section is occupied by trains. [0003] Poor shunting is a common problem in current track circuits. Poor shunting will cause the train wheelset to fail to reliably short-circuit the rails, that is, it ca...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is how to solve the existing bad shunting, which will cause the interlock to make a wrong judgment on whether the section is occupied, and then control the ZC of the bad shunting section to shut down, making other areas controlled by the ZC The section can’t work normally, and the trains on other sections are also braked urgently, which affects the operating efficiency of other trains.
