摘要
文章分析了传统CBTC列控系统在我国城市轨道交通中的弊端,介绍了列车自主运行控制系统(TACS)的系统架构、原理及典型核心功能,并将TACS系统与传统CBTC进行了详细对比分析。TACS以基于LTE-M的车-车/车-地通信为架构,以列车自主运行路径、自主防护和自主运行调整为特征,将轨旁核心控制功能移植至列车上;同时列车运行控制系统与车辆网络控制、牵引和制动等系统高度融合。相较传统CBTC系统,TACS架构更加简单合理,能大大提高线路资源的利用率和系统的控制精度,降低项目建设和运营成本20%~30%,项目工程施工、调试周期可缩短20%~30%;同时使列车运营组织也更加灵活,可大幅提升线路运营效率,列车运行系统更安全、可靠。
This paper analyzes the disadvantages of traditional CBTC system in China's urban rail transit,introduces the system architecture,principle and typical core functions of TACS(train autonomous circumambulation system),and gives a detailed comparison and analysis between TACS and traditional CBTC system.TACS is based on train to train and train to ground LTE-M-communication,which is based on train self-discipline,and characterized by train autonomous operation path,autonomous protection and autonomous operation adjustment.The trackside core control function is transplanted to the train.At the same time,TACS is highly integrated with vehicle network control,traction and braking system.Compared with the traditional CBTC system,the systen architecture of TACS is simpler and more reasonable,which greatly improves the utilization rate of line resource as well as the control accuracy.In the meantime,it reduces the project construction and operation costs by 20%~30%,and also reduce the project construction and commissioning cycles by 20%~30%.Besides,TACS is also more flexible in operation organization,which greatly improves the line operation efficiency,and the system is safer and more reliable.
