自动化车辆段内的车辆段信号系统与试车线信号系统整合方案研究

目前国内城市轨道交通的自动化车辆段中车辆段信号系统和试车线信号系统大多采用不同的联锁系统,导致出现试车线设备与车辆段联锁设备的接口设计方案多、外部接口电路复杂等问题。为此,提出了一种整合车辆段信号系统和试车线信号系统的改进方案:在既有自动化车辆段联锁以及ATP(列车自动防护)、ATO(列车自动运行)系统功能的基础上,扩大其控制范围,扩展试车线功能,完全将试车线纳入自动化车辆段控制范畴。该改进方案在自动化车辆段ATC(列车自动控制)系统的基础上增加了试车线特有的功能,并增加了部分特殊模拟条件,使得车辆段ATC系统与试车线ATC系统得以有效整合,满足车辆段和试车线的功能要求。该方案可减少信号系统及其附属工程的投资,并可减少运营管理接口,减少设备维修工作量。

Research on the Integration System of Depot Signal and Testing Line Signal in Automatic Vehicle Depot

At present,most of the automatic depot signal and the testing line signal systems of urban rail transit in China adopt the independent interlocking system,leading to many complicated external interface circuit problems caused by interface design schemes between the testing line equipment and the depot interlocking equipment.In this paper,an improved scheme to integrate the automatic depot signal system and the testing line signal system is put forward.On the basis of the existing automatic depot interlocking and ATP(automatic train protection),ATO(automatic train operation)system functions,the improved scheme will expand its control scope and the functions of the testing line,bring the testing line completely into the control of the automatic depot.Also,the improved scheme adds special functions of the testing line and some special simulation conditions on the basis of automatic depot ATC(automatic train control)system,making an effective integration of the ATC systems of the depot and the testing line,so as to meet the functional requirements of both.The scheme can reduce the investment of signal system and its ancillary works,at the same time reduce the operation management interfaces and the workload of equipment maintenance.
