摘　　要：[目的]以锡澄线(无锡至江阴城际轨道交通)与既有无锡地铁1号线贯通工程为基础,研究信号系统贯通设计方案。[方法]结合未来存在的拆分需求,从贯通以及拆分对运营线路影响最低的原则出发,介绍了贯通线路信号系统整体设计架构和信号系统贯通方案关键技术。重点研究了:SDH(同步数字体系)组网技术与工业交换机骨干网的贯通设计方案,该方案可以更高的冗余度保证运营网络可靠性;LTE(长期演进)与WLAN(无线局域网)的贯通设计方案,该方案可通过合理切换区设置保证车地通信平滑稳定切换;两线不同限速(120 km/h和80 km/h)列车车载系统配置原则,采用该原则可保障列车在共线区域的运行调整能力和高速列车的系统能力,以及接口站信号系统边界设计和新旧计轴系统的兼容性设计。[结果及结论]解决了同一信号系统列车在不同限速等级线路上运行以及不同车地通信制式互通的难点,提供了便于拆分的预留设计方案。[Objective]Based on the Xicheng Line(Wuxi to Jiangyin Intercity Rail Transit)and the existing Wuxi Metro Line 1 through⁃operation project,it is aimed to study the de⁃sign scheme for signaling system through⁃operation.[Method]Considering future separation requirements,the design scheme prioritizes minimizing the impact on operational lines during both integration and separation.The overall design architecture and key technologies of the through⁃operation line signaling system are introduced.The following aspects are emphatically studied:he through⁃operation scheme for SDH(synchronous digital hierarchy)networking technology and industrial switch backbone network,ensuring higher redundancy and operational network reliability;the through⁃operation design scheme for LTE(long⁃term evolution)and WLAN(wireless local area network),which ensures smooth and stable transitions in vehi⁃cle⁃wayside communication,through reasonable setup of han⁃dover zones;the configuration principles for train on⁃board systems operating at different speed limits(120 km/h and 80 km/h),ensuring train operational adjustment capability in shared sections and the system capability of high⁃speed trains,the boundary design of the signaling system at interface stations and the compatibility design of old and new axle counting sys⁃tems.[Result&Conclusion]The challenges of trains operat⁃ing with the same signaling system on lines with different speed limits and ensuring interoperability between different vehicle⁃wayside communication systems are addressed,providing a pre⁃reserved design scheme that facilitates future separation.
