多网融合下的市域铁路列车控制系统方案研究

Scheme of City Railway Train Control Sys-tem under Multi-network Integration

目前能够兼容CTCS(中国列车运行控制系统)和CBTC(基于通信的列车控制)的信号系统正在研发中。信号系统能否实现互联互通,已成为多网融合下列车在不同信号制式轨道交通线路上混跑的重中之重。以CTCS和CBTC为研究对象,分析两者的技术特点和兼容可行性,研究了市域铁路列车控制系统选型的各种可能性方案。针对CBTC和CTCS两种信号制式,提出了双车载设备方案和一体化车载设备方案,并对两个车载设备方案进行了优缺点分析,以期为多网融合下市域铁路信号系统的互联互通性设计提供参考。

At present,the signaling system that accommodates both CTCS(China train control system)and CBTC(communication based train control)is under development.Whether the signaling system can realize interoperation has become the top priority for train mixed operation on rail transit lines with different signal systems under multi-network integration.Taking CTCS and CBTC as the research objects,the technical characteristics and compatible feasibility of both are analyzed,the possibilities of various selection schemes for city railway train control signaling system are studied.Targeting the signaling formats of CBTC and CTCS,the double on-board equipment and the integrated on-board equipment are recommended,the advantages and disadvantages of the two schemes are analyzed respectively,so as to provide reference for the interoperability design of city railway signaling system under multi-network integration.
