CBTC系统中全自动运行列车的双向移动授权管理方法

Bidirectional Movement Authorization Management for FAO Trains in CBTC System

[目的]CBTC(基于通信的列车控制)系统的全自动运行线路,在技术层面上仍然缺少统一的设计标准和运营作业规范。为在不影响运营效率的条件下,实现列车过停站台退行时对后方轨道区域的防护,需要研究CBTC系统中全自动运行列车双向移动授权的通用管理方法。[方法]基于双向安全防护的典型场景,分析了列车需执行双向作业时轨旁区域控制器和联锁需要防护的关键因素和线路范围。研究了移动授权中的多方协作机制,提出了CBTC列车双向运行移动授权的通用管理方法。[结果及结论]所提管理方法不改变传统CBTC系统的整体架构,仍以区域控制器和联锁子系统共同作为区域控制中心,通过区域控制器、联锁子系统及车载控制器的协作,实现了列车双向运行移动授权管理。

[Objective]FAO(fully automatic operation)lines of CBTC(communication-based train control)system still lacks unified design standards and operational protocols at the technical level.To ensure protection of the rear track area when a train reverses at a station without compromising operational efficiency,it is necessary to develop a general management method for FAO train bidirectional movement authorization in CBTC system.[Method]Based on typical scenarios requiring bidirectional safety protection,the critical factors and track areas that need trackside controller and interlocking system protection are analyzed when a train needs to perform bidirectional operations.The multi-party collaborative mechanism involved in movement authorization is investigated,and a general management method for CBTC train bidirectional movement authorization is proposed.[Result&Conclusion]The proposed management method does not alter the overall architecture of the traditional CBTC system.It continues to use the trackside controller and interlocking subsystem as the regional control center.Through the collaboration of trackside controller,interlocking subsystem,and onboard controller,the method effectively enables train bidirectional movement authorization management.
