摘要
分析了传统CBTC(基于通信的列车控制)系统下计轴及其子系统在使用过程中所出现的问题,提出了基于信标的列车次级定位系统应用技术。该技术采用既有ATP(列车自动防护)系统的地面应答器,通过车地系统结合的方式,为CBTC系统提供了一种新的列车次级定位检测方案。该技术与计轴系统具有相同的安全等级。基于上海城市轨道交通超大网络的运营管理需求,进一步对基于信标的列车次级定位系统的架构及应用场景进行研究。应用效果表明,基于信标的列车次级定位系统能实现正线信号控制区域的无计轴化,具有简化系统结构、便于安装、抗干扰能力强,以及可减少设备维护工作量、降低维护综合运营成本等优点,是未来新线线路建设和既有线路改造的首选。
The problems caused by axle counting and its subsystem of conventional CBTC(communication-based train control)system during operation are analyzed,and a beacon-based train secondary positioning system application technology is proposed.The technology adopts balise from existing ATP(automatic train protection)system,through vehicle-wayside system mergence,a new train secondary positioning detection scheme is proposed for CBTC system.This technology has same safety level as axle counting system.With the operation and management requirement of Shanghai urban rail transit super-large-scale network,the beacon-based train secondary positioning system architecture and application scenario are further studied.Application results show that beacon-based train secondary positioning system can realize non-axle-counting in main line signal control area,having advantages of simplified system structure,easy installation,high anti-interference ability,so that equipment maintenance workload is reduced,as well as maintenance cost of overall operation,becoming the primary choice for future new line construction and existing line reconstruction.
