都市圈轨道交通多网融合的信号系统方案研究

Research on Signaling System Scheme of Multi-network Integration of Metropolitan Rail Transit

结合都市圈网络化、公交化特点,提出都市圈轨道交通信号系统融合的技术目标,即采用现有技术C2/C2+ATO与CBTC系统的融合以及采用新型互联互通技术的信号系统间的融合。分析现有信号主流的CTCS系统与CBTC系统的地面和车载设备在技术层面、工作机理、系统功能等差异的基础上提出“地对车兼容”和“车对地兼容”的互联互通方案,结合各目前相关单位在开展的研究情况,分析新型市域铁路互联互通技术路线。

According to the network and public transportation characteristics of the metropolitan area rails,the technical goal of integration of signaling systems is proposed,which is,the integration of existing C2/C2+ATO and CBTC systems and the integration of signaling systems using new interconnection technology.Based on the analysis of diff erences in technical level,working mechanism and system function between the ground and vehicle equipment of the existing mainstream CTCS and CBTC systems,the interconnection schemes of"ground-to-vehicle compatibility"and"vehicle-toground compatibility"are proposed.Combined with the current researches of relevant manufacturers,the new interconnection technology route of suburban railway is analyzed.
