摘要:

为了减少城市轨道交通列车ATO（列车自动运行）控制系统的故障概率，合肥轨道交通1、2号线列车ATO模式下的牵引和制动控制电路在车辆侧和信号侧均进行了冗余设计。通过深入分析发现，控制电路冗余设计在接口上存在一定缺陷，导致牵引和制动控制电路发生故障概率增加1倍，且缩短了AMTDR（牵引指令继电器）、AMBDR（制动指令继电器）的使用寿命。针对此问题，提出了2个AMTDR、AMBDR得电逻辑的设计优化方案。

Abstracts:

In order to reduce the failure probability of ATO (Automatic Train Operation) control system of urban rail transit train, traction and braking control circuits of Hefei Metro Line 1 and Line 2 in ATO mode are designed with redundancy on both vehicle sides and signaling sides. Through indepth analysis, it is found that the control circuit redundancy design has some defects in the interface, which leads to doubled fault probability of traction and braking control circuits, shortening the service life of AMTDR (traction instruction relay) and AMBDR (braking instruction relay). To solve this issue, two technical schemes to optimize the power generation logic of AMTDR and AMBDR are proposed.
