摘要:
随着城市轨道交通信号系统闭塞方式的变化，轨旁次级列车检测设备正呈逐步减少的态势，但设备总体数量仍较多。在目前主流的CBTC（基于通信的列车控制）系统中，ATP（列车自动保护）采用了主动列车定位系统，次级列车检测设备主要用于降级模式列车的运行。分析了次级列车检测设备在CBTC系统中的主要作用，提出了无次级列车检测设备但可实现其功能的信号系统方案。TACS（列车自主运行系统）不依赖于次级列车检测设备，介绍了该系统实现列车筛选、降级列车行车组织和道岔资源管理的方案。TACS可实现优化信号系统架构、降低信号系统运营和维护成本、压缩轨旁设备机房面积及减少信号系统设备用电量的作用。
Abstracts:
With the change of blocking method of urban rail transit signaling system, the secondary train detection equipment on wayside is gradually decreasing, but the total quantity of the equipment is still large. Currently, in the mainstream CBTC (communication\|based train control) system, ATP (automatic train protection) adopts the positive train localization system, and the secondary train detection equipment is mainly used for the operation of trains in degrade mode. The main functions of the secondary train detection equipment in CBTC system are analyzed, and the signaling system solution to realize function without secondary train detection equipment is put forward. TACS (train autonomous control system) do not rely on the secondary train detection equipment. The solution to realize train sweeping, degrade train operation and switch area resource management is introduced. TACS system can optimize signaling system architecture, reduce the operation and maintenance cost, and reduce the wayside equipment room area and signaling equipment power consumption.
