摘　　要：[目的]为实现苏州市与上海市的客流衔接,苏州轨道交通3号线与11号线在唯亭站单点衔接,乘客通过站厅付费区进行换乘。该站厅换乘方案限制了3号线与11号线的运能。为满足运能提升的迫切需求,需对3号线与11号线贯通运营信号系统进行升级改造。[方法]分析了3号线与11号线信号系统既有现状和技术差异;提出了基于不同无线通信制式、满足两线贯通运营需求的信号系统改造方案;根据3号线与11号线信号系统改造项目工程筹备计划,设计了信号系统改造实施方案,分别对信号车载子系统、ATS(列车自动监控)子系统、正线车站信号子系统及段场信号子系统进行改造。[结果及结论]通过对3号线与11号线信号系统进行适应性改造,实现了列车跨线无人驾驶运行,车载ATC(列车自动控制)设备、ATS服务器、工作站硬件兼容互换,车地无线通信无扰自动切换。列车可在3号线与11号线两线以无扰全自动驾驶模式贯通运行,提高了城市轨道交通运行效率,提升了乘客出行体验。[Objective]To facilitate the integration of passenger flow between Suzhou and Shanghai,Suzhou Rail Transit Line 3 and Line 11 are connected at Weiting Station,where passengers currently transfer via the concourse within the fare-paid zone,resulting in a restriction of the operational capacity for both Line 3 and Line 11.To meet the urgent need for capacity enhancement,a renovation plan of the signaling system for Line 3 and Line 11 through train operation is required.[Method]The existing conditions and technical differences between the signaling systems of Line 3 and Line 11 are analyzed.Based on different wireless communication standards,a signaling system renovation plan is proposed to meet the requirements of the through train operation between two lines.The implementation plan for the signaling system renovation is designed according to the project preparation schedule for Line 3 and Line 11 signaling system upgrade,focusing on modifications of the on-board signaling subsystem,ATS(automatic train supervision)subsystem,mainline station signaling subsystem,and depot signaling subsystem.[Result&Conclusion]Through adaptive modifications to the signaling systems of Line 3 and Line 11,train cross-line driverless operation is achieved,the compatibility and interchangeability of on-board ATC(automatic train control)equipment,ATS servers,and workstation hardware are implemented,allowing for uninterrupted automatic switching of vehicle-wayside wireless communication.Trains can operate seamlessly across Line 3 and Line 11 in FAO(fully automatic operation)mode,enhancing the operational efficiency of urban rail transit and improving the passenger travel experience.
