Method and device for determining occupied position of train

Abstract

The embodiment of the invention discloses a method and device for determining the occupied position of a train. A target controller is constructed based on CI and QC. The method for determining the occupied position of the train includes the steps that the target controller collects position information of the current train and determines the maximum travel distance of the head of the current train and the maximum travel distance of the tail of the current train; and the target controller determines the occupied position of the current train based on the position information, the maximum travel distance of the head and the maximum travel distance of the tail. By means of the method and device, the train operation efficiency and the train operation capacity are effectively improved, the resource consumption can be reduced, communication delay between the QC and the CI is reduced, the accuracy of the determined train occupied position can be effectively improved, the train operation efficiency is further improved, and the train operation capacity is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method and a device for determining the occupied position of a train. Background technique [0002] With the continuous development of rail transit technology, more and more people choose rail transit to travel. In order to ensure the safety of train operation and passenger safety, how to determine the occupied position of the train has become particularly important. [0003] At this stage, the train occupancy position is usually determined by CBTC (Communication Based Train Control System, communication-based automatic train control system). Specifically, the train occupancy position can be determined through CI (Computer Interlock) and ZC (Zone Controller). The axle counting section is a message of an occupied state. Since there is a communication delay between ZC and CI, ZC can determine that the non-communicating vehicle may be in the aforementioned axle counting sec...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the axle counting section in the occupied state reported by the CI or the adjacent idle state axle counting section before and after the axle counting section may be misjudged as the occupied position of the non-communicating train, so that the movement authorization of the following vehicle cannot Extend to the aforementioned axle counting sections, thereby affecting the train operation efficiency
