城市轨道交通全自动运行线路自动化场段库线设计方案

Design of Automatic Depot Stabling Line for Urban Rail Transit FAO Line

自动化场段是城市轨道交通全自动运行线路标准配置之一。基于CBTC(通信的列车控制)的性能要求及IEEE Std 1474.1:2004《CBTC的性能和功能要求》所定义的安全制动模型计算得到的列车安全防护距离一般较大,由此导致自动化场段的库线(尤其是双列位停车库线)的设计长度较长,往往受到建设用地的制约。为此,基于能量监控禁止模型安全算法建立了列车自动入库的理论方法。该理论方法可在场段土建条件受限、导致库线长度不足时有效解决列车自动入库并精确停车的问题,还可用于指导全自动运行项目的自动化场段设计。

The automatic depot is one of the standard confi-gurations of urban rail transit FAO(fully automatic operation)line.Based on the performance requirements of CBTC(communication based train control)and the safety braking model defined by the IEEE Std 1474.1—2004 standard"CBTC Performance and Functional Requirements",the calculated train safety protection distance is generally larger,leading to the design of a relatively longer stabling line length(especially the double-row stabling)in the automatic depot,that is often restricted by the construction land.Therefore,a theoretical calculation of train automatic warehousing is established through the safety algorithm of energy monitoring prohibition model.The theory can effectively solve the problems of train automatic warehousing and accurate docking when the ci-vil construction conditions of the depot are limited and the stabling line length is insufficient,it can also guide the design of the automatic depot for FAO project.
