地铁列车紧急制动的原因分析及解决措施

Cause Analysis and Solution Measures for Emergency Braking of Subway Trains

地铁列车紧急制动是指在地铁行驶过程中,当列车遇到紧急情况时,驾驶员需要立即按下紧急制动按钮,使列车停止运行。地铁系统会自动通知相关部门和救援人员,以便及时处理紧急情况。本文介绍了长沙地铁4号线列车紧急制动故障产生原理,通过试验模拟重现紧急制动故障,分析故障数据,查找引起该故障的原因,并制定合理的整改措施,有效解决紧急制动故障。

Emergency braking of subway trains refers to a measure taken by drivers to immediately stop the train in case of an emergency during subway operation,in order to ensure the safety of passengers.When the train encounters an emergency situation,the driver needs to immediately press the emergency brake button to stop the train from running.The subway system will automatically notify relevant departments and rescue personnel to handle emergency situations in a timely manner.This article introduces the principle of emergency braking faults in trains on Changsha Metro Line 4.Through experimental simulation,the emergency braking faults are reproduced,fault data is analyzed,the cause of the fault is identified,and reasonable rectification measures are formulated to effectively solve the emergency braking faults.
