地铁渡线道岔联动及单动控制的故障处置方案比较

渡线道岔控制根据信号设备不同有联动控制和单动控制2种方案。从渡线道岔故障后的行车处置出发,对不同控制方案产生的影响进行分析和反思。在“失去表示”故障情况下,两种控制方案的处置方法和安全效率均有较大区别。采用单动控制的方案虽逻辑复杂,但故障处置更为灵活,是较好的控制方案。

Comparison between Linkage Control and Single-action Control of Subway Crossover Switch in Fault Disposal

There are two schemes:linkage control and single-action control according to different signal devices.From the aspect of traffic management after a crossover switch fault,the influence of different design schemes is analyzed and introspected.In case of expression loss,there are significant differences between disposal methods in terms of efficiency and security.The single-action control scheme has complex logic,but it is more flexible in processing faults and is therefore considered as a better control scheme.
