摘　　要：文章简述了地铁车门系统,以北京地铁2号线列车为例,分析其“门旁路”的问题。细化讨论列车牵引系统、继电器电路与异常状态,以及在发生故障后信号系统降级处理的情况。根据列车故障问题,避免异常车辆驶出正线过程对其他列车运营造成严重影响,优化“门旁路”的电路,使全部触点均能迅速被旁路。This paper briefly describes the subway door system,and takes the train of Beijing Metro Line 2 as an example to analyze the problem of“door bypass”.Discuss in detail the train traction system,relay circuit and abnormal state,as well as the degradation of signal system after failure.According to the train fault problem,avoid serious impact on other train operation during abnormal vehicle driving out of the main line,optimize the circuit of“door bypass”,so that all contacts can be bypassed quickly.
