摘要
[目的]上海轨道交通6号线运行多年,其信号系统出现设备老化、故障频发问题。为提升系统的可靠性、适配性和运营效率,有必要探讨上海轨道交通6号线信号系统大修改造方案。[方法]基于对信号系统现状和运营情况分析,提出了基于设备更新的CBTC(基于通信的列车控制)系统功能恢复改造方案(方案一)、采用全新的TACS(列车自主运行系统)方案(方案二)、基于DTO(有人值守的列车自动运行)模式的CBTC系统全面升级改造方案(方案三)。分析了各方案的信号系统架构及改造主要存在的问题。经综合比选,最终确定了方案三为最优改造方案。采用仿真分析验证的方法,以线路实际改造情况为依托,分析比较了改造前后的旅行速度、旅行时间、正线追踪间隔及停站时间。[结果及结论]方案三能缩短追踪间隔、延长停站时间,有效提升上海轨道交通6号线的运营安全性和服务水平,改善信号系统的可靠性和运营效率。
[Objective]After years of operation,Shanghai Rail Transit Line 6 signaling system faces equipment aging and frequent failures.To enhance this system reliability,adaptability,and operational efficiency,it is imperative to develop an overhaul plan for the signaling system of Shanghai Rail Transit Line 6.[Method]Based on an analysis of current signaling system status and operational performance,three solutions are proposed:functional restoration of the CBTC(communication-based train control)system through equipment renewal(option 1);implementation of a new TACS(train autonomous circumnavigation system)plan(option 2);comprehensive upgrade of the CBTC system based on DTO(driverless train operation with attendant)mode(option 3).The signaling system architecture and primary challenges for each option are examined.After comprehensive comparison,option 3 is identified as optimal.Using simulation analysis verification method,based on the actual line upgrading conditions,the travel speed,journey time,mainline tracking interval,and dwell time before and after upgrade are analyzed and compared.[Result&Conclusion]Option 3 effectively shortens train tracking intervals,extends dwell time,and significantly enhances operational safety and service quality on Shanghai Rail Transit Line 6,improving both the reliability and operational efficiency of signaling system.
