摘　　要：为推动市郊铁路和城市轨道交通互联互通,加快实现轨道交通“四网融合”,必须建设“双流制”铁路,因此需克服列车以不降弓、全自动无感的方式完成交直流供电制式转换成为“双流制”供电制式的技术难题。江跳线是全国首条开通运营的双流制市域(郊)铁路,以此为例对轨道交通信号系统进行研究,通过在地面设置信标,向信号车载设备传送信息,进而向车辆发送位置、动作命令等信息,辅助和引导车辆安全平稳地通过交直流转换区。采用的信号系统设置方案有效保证了双流制列车的运行,填补了国内双流制核心技术空白。In order to promote the interconnection between suburban railway and urban rail transit and accelerate the realization of the"four networks integration"of rail transit,it is necessary to build a"double-current system"railway.Therefore,it is necessary to overcome the technical problems that trains can complete the conversion of AC-DC power supply system into"two-flow system"power supply system by means of automatic and non-inductive way without falling arch.Jiangtiao Railway is the first double-current system municipal(suburban)railway in China,it’s rail transit signal system is studied.By setting beacons on the ground,information is transmitted to on-board signal equipment,and then position,action command and other information are sent to the vehicle to assist and guide the vehicle to pass through the AC/DC conversion zone safely and smoothly.The practice proves that the signal system setting scheme described in this paper effectively ensures the operation of double-current system trains and fills the core technical gap of domestic double-flow system.
