城市轨道交通基于通信的列车自动控制系统中站台轨旁无源应答器的布置方案

Layout Design of Passive Balise in Platform Trackside under CBTC System of Urban Rail Transit

[目的]应答器的布置数量与安装位置直接影响城市轨道交通的线路安全、运营效率及项目成本,需要对CBTC(基于通信的列车自动控制)系统下的站台轨旁无源应答器布置设计方案进行研究。[方法]介绍了CBTC系统下站台精准停车的设计原理,详细阐述了停准应答器、第一接近应答器及第二接近应答器的布置规则和方法。以郑州地铁10号线CBTC系统为研究对象,对其站台轨旁无源应答器的布置方案进行了说明。[结果及结论]阐述的站台轨旁无源应答器布置方案,实现了列车进站时在站台的精准停车。在确保列车安全与运营效率的前提下,轨旁无源应答器布置数量达到最少,减少了项目成本。本方案在上海、成都、深圳、郑州等地多条城市轨道交通线路的信号系统中应用效果良好。

[Objective]The number and installation location of balises directly affect the line safety,operation efficiency,and project cost of urban rail transit.Therefore,it is necessary to study the design scheme of the balise layout in platform trackside under CBTC(communication based automatic train control)system.[Method]The design principle of accurate platform parking under the CBTC system is introduced,the layout rules and methods of the balises for the accurate stopping balise,the first and the second proximity balises are expounded in detail.With the CBTC system of Metro Line 10 in Zhengzhou as the research object,the layout scheme of the platform trackside balise is illustrated.[Result&Conclusion]The layout scheme of the passive balise in platform trackside,as explained,achieves accurate parking on the platform when the train enters the station.On the premise of ensuring train safety and operation efficiency,the minimized number of trackside passive balise reduces project cost.The proposed scheme has good application effect in the signal system of the urban rail transit lines in Shanghai,Chengdu,Shenzhen,Zhengzhou,and other cities.
