Station interlocking logic processing method and device

Abstract

The invention provides a station interlocking logic processing method and device. The method includes the steps that small access virtualization processing is conducted on station access; after an access sequence table is obtained, if a progressive change happens to the access sequence table, interlocking processing is conducted on all access commands not sending out admission authorization in theaccess sequence table one by one; if a route change happens to the access sequence table, all access in a station is unlocked, a permission used for canceling access idleness and admission is sent out, and then interlocking processing is conducted on all the access commands in the access sequence table; after it is detected that a train sequentially occupies the cleared access, the permission used for canceling access idleness and admission is sent out to a train control system; whether small access occurs in following access or not is judged, and according to a judgment result, the small access is locked or unlocked again after being locked or unlocked; and a permission for small access idleness and admission is sent out to the train control system according to the small access locked and unlocked again. By the application of the method and device, train tracking efficiency can be improved.

Description

technical field [0001] The invention relates to the field of railway signal systems, in particular to a station interlock logic processing method and device. Background technique [0002] Station interlocking logic processing includes checking and confirming the interlocking relationship among turnouts, sections, and signals in the station, checking and checking between interlocking areas and blocking relationships with interval lines, and opening signals, so as to ensure It is safe for trains to run in the fork area of ​​the station, avoiding frontal or side conflicts. The protection object of station interlocking logic processing is usually the overall route between the end and the end, and the route can refer to all the ways for trains or shunting trains to run from one point to another. [0003] The current logic processing method of station interlocking is usually as follows: manually pressing the end-to-end button of the route, or the command of the end-to-end button ...

AI Technical Summary

Problems solved by technology

[0004] With this method, it is necessary to wait for the entire route between the end and the end to be checked before opening the signal, and then to provide the train control system with an authorization to allow access when the route is idle, so that when the train is running at the station, the tracking of the station The interval cannot improve the tracking efficiency like the interval of the mobile block system, and can only maintain the tracking time and minutes under the current fixed block system
