摘要
列车自主运行系统(TACS)作为新一代城市轨道交通列控系统,在我国应用仍处于初级阶段,工程实践中存在冗余不足、兼容性差、后备运营模式缺失等问题,难以满足高安全性和高可靠性的运营需求。以深圳地铁20号线信号系统工程为背景,对TACS应用中的无线通信技术方案、后备模式、车辆段列车控制、联络线接口等要点问题进行深入研究,形成可行的工程要点设计方案。研究结果表明:无线通信系统采用LTE-A/B+WLAN方案,可增加无线通信系统的冗余能力;后备模式选用基于列车自主定位的降级运行系统,使系统结构更简单;车辆段非自动化区域纳入列车自动控制(ATC)系统管控范围,运营模式设置为有人驾驶模式,可实现系统加人工双重防护;采用专用接口模块实现联络线接口功能,能够有效解决边界管理问题。研究结果可为TACS的推广应用提供一定技术支撑。
As a new generation of train control system for urban rail transit,the application of TACS in China is still in its early stage.In engineering practice,there are problems such as insufficient redundancy,poor compatibility,and lack of backup operation modes,which make it difficult to meet the operational requirements of high safety and high reliability of the TACS.Based on the signal system engineering of Shenzhen Metro Line 20,the key application problems of TACS,such as wireless communication technical scheme,backup mode,train control in depot and liaison line interface,are deeply studied to establish the design of key points of feasible engineering.The results show that LTE-A/B+WLAN scheme can increase the redundancy of wireless communication system,the backup mode of degraded operation system based on train autonomous positioning simplify system structure,the non-automated area of the car depot included in the control of the ATC system and the operation mode set as manned driving can realize double protection by the system and the driver,and the special interface module for the liaison line interface can effectively solve the problem of boundary management.All these research results provide some technical support for promoting the application of the TACS.
