城市轨道交通列车故障救援方案的研究

Research on Fault Rescue Plans for Urban Rail Transit Trains

[目的]城市轨道交通一旦发生故障,需要其他列车救援,就会严重影响后续列车运行和乘客的出行安全。若救援的路径选择不合适,还会对已开通的线路造成二次影响。故需基于救援路径和组织,研究列车救援方案。[方法]分析现有的城市轨道交通列车故障救援程序。结合列车故障救援的实际作业时间和流程,分析列车故障救援过程及作业时间。对一条线路不同位置发生列车故障时的救援路径选择进行了探讨,从救援列车的选择、救援方式的选择和故障列车存放位置的选择三方面入手,对其进行组合,得到列车故障救援的不同方案。以上海轨道交通7号线为例,进行列车故障救援方案的比选和汇总。[结果及结论]把列车故障救援过程分为故障处置、救援准备、救援处置和救援结束4个阶段。基于救援列车的选择、救援方式的选择和故障列车存放位置的选择及组合,得到了上海轨道交通7号线全线列车故障救援方案图。经实践验证,该救援方案能有效地避免二次延误,进而提升地铁服务质量。

[Objective]Once failures occur in urban rail transit,the need for assistance from other trains can significantly impact the subsequent train operation and passenger safety.Improper choices in the rescue path may also lead to secondary effects on already operating lines.Therefore,it is essential to study fault rescue plans based on rescue paths and organization.[Method]Existing procedures for fault rescue of urban rail transit trains are analyzed.Combining the actual operation time and process of train fault rescue,the process and operation time of train fault rescue are analyzed.The discussion includes the selection of rescue paths when a train fault occurs at different locations on a line.By considering the choice of the rescue train,the selection of rescue method,and the location for storing the faulty train,these aspects are combined to derive various fault rescue plans.Taking Shanghai Rail Transit Line 7 as example,the fault rescue plans are compared and summarized.[Result&Conclusion]The train fault rescue process is divided into four stages:fault handling,rescue preparation,rescue operation,and rescue completion.Based on the selection and combination of the rescue train,rescue method,and location for storing the faulty train,a comprehensive fault rescue plan for the entire Shanghai Rail Transit Line 7 is obtained.Through practical verification,this rescue plan can effectively avoid secondary delays,thereby enhancing the quality of metro services.
