摘　　要：地铁列车紧急制动安全回路监测司机紧急制动请求和车辆连挂等信息,当列车分离等原因导致安全回路断开时,触发列车紧急制动,并自动降弓。通过对两种典型地铁车辆安全回路工作原理、触发条件、潜在故障因素等进行研究分析,提出了安全回路设计的优化方案。The request of emergency braking by metro driver and coupling information are monitored by emergency brake safety circuit of metro train. The train emergency brake will be triggered and the pantograph dropped automatically when the safety circuit is broken by train separation. The paper presents the operating principle of safety circuit,triggering conditions and the potential failure factors of two typical metro vehicles,and presents the optimization design of safety circuit.
