地铁信号故障时三种电话闭塞间隔模式的适用性分析

Applicability Analysis of Three Telephone Block Interval Modes in Subway Signal Fault

地铁信号设备故障条件下,可使用电话闭塞维持列车运行。我国地铁有"一站一区间"、"一站两区间"、"两站两区间"三种间隔模式。以三种间隔方式在不同条件下对运营服务的影响作为评价对象进行综合分析,选择了四种典型的故障处置条件,选取有代表性的技术指标,通过运行推演的方法确认列车的延误数据,综合分析乘客影响,提出合理的推荐方案,并为解决该问题提供一个可行的计算方案。

In case of subway signal equipment failure, the telephone block can be used to maintain the train operation. There are three subway interval modes in China： one section for one station; two sections for one station and two sections for two stations. In the paper, the impact of the three interval modes on operating services in different conditions is analyzed, four typical fault disposal conditions and typical technical indicators are selected. In addition, the subway delay data are verified through the running posteriori method, and the impact on passengers are comprehensively analyzed. Finally, a feasible computing solution is recommended to solve the problem.
