摘　　要：市域铁路是适用于都市圈中心城市城区连接周边城镇组团的轨道交通系统,提供公交化、大运量、快速便捷的交通服务。为实现市域铁路3 min追踪间隔的目标,市域铁路列控系统需要增加自动折返功能,并将站后自动折返间隔时间压缩到3 min以内。分析市域铁路系统需求,提出一种基于成熟的CTCS2+ATO列控系统开发适用于市域铁路的列控系统,并增加自动折返功能。详细阐述站后自动折返过程,包括驶入折返线流程、自动换端流程和驶出折返线流程。为实现系统支持自动折返功能,对车辆、车载设备和地面设备进行功能分配,并给出可行的技术方案。搭建市域铁路半实物仿真平台,进行站后无人自动折返仿真验证实验,验证站后自动折返功能和站后自动折返时间。通过实验证明对车辆、车载设备和地面设备进行的功能分配可支持CTCS2+ATO列控系统实现自动折返功能;提出的自动折返流程能够实现安全、高效的无人自动折返,在保证行车安全的情况下,提高站后自动折返效率;采用本文提出的优化方案和技术可将站后自动折返过程总时间压缩到160 s以内,能够满足市域铁路3 min自动折返时间要求。The urban railway is a rail transit system which is suitable for connecting the central city of metropolitan area with the surrounding towns,and provides public transportation,large capacity,fast and convenient transportation services.In order to achieve the goal of 3min tracking interval of urban railway,the train control system of urban railway needs to increase the automatic turn back function and reduce the automatic turn back interval after the station to less than 3 min.Analyze the requirements of urban railway system,propose to develop a train control system suitable for urban railway based on mature CTCS2+ATO train control system,and add automatic turn back function.The automatic turn back process after the station is described in detail,including the process of driving into the turn back line,the process of automatic end changing and the process of driving out of the turn back line.In order to realize the automatic turn back function supported by the system,the functions of trains,on-board equipment and wayside equipment shall be allocated,and a feasible technical scheme shall be given.Set up the test platform of semi real equipment and semi simulation equipment of the city railway,carry out the simulation and verification experiment of unmanned automatic turn back after the station,and verify the automatic turn back function and time after the station.Through experiments,it is proved that the function allocation of train,on-board equipment and wayside equipment can support the automatic turn back function of CTCS2+ATO train control system;The proposed automatic turn back process can realize safe and efficient unmanned automatic turn back,and improve the efficiency of automatic turn back after the station under the condition of ensuring traffic safety;By adopting the optimization scheme and technology proposed in this paper,the total time of automatic turn back process behind the station can be reduced to less than 160 s,which can meet the requirements of 3 min automatic turn back time for urban railways
