城市轨道交通运营列车故障影响仿真分析系统

摘要

研究城市轨道交通列车故障影响的分析方法,采用仿真技术描述故障车、救援车、连挂车、运营车等不同对象运动过程.以上海轨道交通为背景,梳理列车故障处置的一般作业流程,并将线路运营划分为正常、故障、救援和恢复4种状态;针对列车自动保护ATP系统切断后连挂车与运营车之间的追踪运行过程建立模型与算法;在仿真系统中,开放了对故障事件以及救援方案的信息访问和管理,支持分析不同条件下(如故障处置流程、连挂车运行组织、线路配线设计等)列车故障对线路运营的影响.建立上海轨道交通8号线列车故障影响仿真分析平台,实现对某一历史故障事件的过程模拟,并分析故障地点、连挂车运行速度和退出点对线路“故障”和“救援”阶段列车运行的影响,论证了仿真分析系统的有效性.%Focusing on the method for analyzing impacts of metro train faults on operations,the simulation technology is used to describe moving processes of the disabled train,the rescue train,the articulated train,and the normal operation train.Taking Shanghai metro operation as the background,the paper first makes a review of the general process of disposing the train failure,and classifies the line operation conditions into four categories,i.e.,normal operation state,train failure state,rescue state,and recovery state.Then,the paper builds the calculation model and algorithm for movements of the articulated train and the normal operation train after cutting off the automatic train protection (ATP).For the developed simulation system,it opens the access and management of the failure event and rescue program information,which helps to analyze the impacts of train failure on the line operation under different factors,such as faults disposal processes,operation of the articulated train,setting of the packing tracks for the disabled train,etc.Finally,using the simulation and analysis system for the Line 8 of Shanghai rail transit,the paper simulates the process of a historical train failure and rescue event,and assesses the impacts of the faults location,the running speed of the articulated train,and the packing tracks for the disabled train on train operations.The case study demonstrates the applicability and validity of the impact analysis system.
