基于CTC系统的城际折返站车次号实现自动变更的研究

Research on Realizing Automatic Change of Train Numbers of Inter-city Railway Turn-back Stations Based on CTC System

从CTC系统实现车次号跟踪的原理出发,阐述列车到达折返站后CTC系统车次号自动变更逻辑的实现过程,通过白云机场北折返站为例,说明站内折返和站后折返的情景下实现车次号自动变更功能的过程和作业方式,在车次密集、公交化运营需求的趋势下,解决调度员在折返站手动修改车次可能造成的车次修改错误、车次修改延时等原因导致的信号不能按照计划开放的问题。

Based on the principle of CTC system to realize the tracking of train number,this paper expounds the process of realizing the logic of automatic change of train number of CTC system after the train arrives at the turnback station.Taking Baiyun International Airport North Turnback Station as an example,the process and operation mode of realizing the automatic change function of train number in the situation of turning back in or after the station are illustrated.It solves the problem that the signal cannot be cleared according to the plan due to the train number modifi cation error and the train number modifi cation delay caused by the dispatcher manually modifying the train number at the turnback station.
