北京市轨道交通亦庄线工程信号系统是国产化的CBTC线路,同时设计了基于计轴的后备系统。作为整个信号系统的调度指挥中心,智能列车调度和监督ATS子系统既要满足既有的进路闭塞列车控制系统的控制特点,还要支持基于CBTC移动闭塞的列车控制系统,这对既有的ATS子系统产生了较大的影响,通过对两种闭塞模式控制系统的具体分析和比较,探讨了在两种列车控制模式下以及在混跑模式下ATS子系统的主要结构、功能和特点。
The Beijing Railway Yizhuang Engineering Signal System is a domestic CBTC circuit, while designing a back-up system based on axle counting. As the dispatching command center of the whole signal system, the intelligent train dispatching and supervision ATS subsystem not only satisfies the control characteristics of the existing approach blocking train control system, but also supports the train control system based on CBTC mobile occlusion, ATS subsystem has a greater impact. Through the analysis and comparison of two kinds of blocking mode control systems, the main structure, functions and features of ATS subsystem in two train control modes and in hybrid mode are discussed.
