深惠城际铁路CTCS2+ATO列控系统自动折返方案研究

Research on Automatic Turn-Back Scheme of CTCS2+ATO Train Control Systemof Shenzhen-Huizhou Intercity Railway

基于目前粤港澳大湾区城际铁路建设规划及深惠城际铁路基本情况,梳理目前城市轨道交通以及城际铁路2种轨道交通制式下列车折返模式,调研装备CTCS2+ATO列控系统的城际铁路的情况,发现列车在车站进行折返作业一般由人工完成,存在耗时长、效率低、操作繁琐等问题。通过分析深惠城际铁路的实际需求,从车辆和设备改造、优化作业流程等角度,提出具体的CTCS2+ATO列控系统自动折返实施方案设计,方案主要是对动车组、车载设备、调度集中(CTC)、列控中心(TCC)、通信控制服务器(CCS)等进行一定的修改,并设计一套折返作业流程。研究设计的自动折返方案旨在实际工程项目中得到应用,以提高列车折返作业效率,增加动车组运用周转率,实现运营效率的提升。

In view of the construction planning of intercity railways in the Guangdong-Hong Kong-Macao Greater Bay Area and the situation of Shenzhen-Huizhou Intercity Railway,this paper explained the current train turn-back modes of urban rail transit and intercity railways.According to the investigation of intercity railways equipped with China train control system level-2+Auto Train Operation(CTCS2+ATO)train control system,it was found that the turn-back operation of trains at stations was generally completed manually,which was time-consuming,inefficient,and cumbersome.By studying the needs of Shenzhen-Huizhou Intercity Railway,a specific implementation scheme was designed from the perspectives of train and equipment transformation and optimization of operation procedures.The scheme mainly modified the electric multiple units(EMUs),on-board equipment,centralized traffic control(CTC),train control center(TCC),communication control server(CCS),etc.,and designed a set of turn-back operation procedures.The automatic turn-back scheme aims to be applied in actual engineering projects,so as to improve the efficiency of train turn-back operation,increase the turnover rate of EMUs,and enhance operational efficiency.
