CBTC(基于通信的列车控制)系统普遍采用分布式的移动授权管理架构,不同的移动授权单元控制不同的控区。介绍了正常模式下通信列车通过控区边界的过程,逐一分析了非通信列车在接车控区MAU(移动授权单元)发生故障、发车控区MAU发生故障及两个连续控区MAU均发生故障模式下的系统反应;并论述了在分布式移动授权管理架构运用过程中涉及到的跨控区列车运行的管理问题,最终提出相应的系统解决方案。
CBTC (Communication Based Train Control) system generally adopts distributed mobile authorization management architecture, and different mobile authorization units control different control zones. This paper introduces the process that the communication train passes the boundary of the control area in normal mode and analyzes the failure of the MAU (Mobile Authorization Unit), the failure of the MAU in the transmission control area and the failure of the MAUs in the two continuous control areas Mode system response; and discusses the management of distributed mobile entitlement management system involved in the cross-zone operation of the train management issues, and ultimately propose the appropriate system solutions.
