列控中心是 CTCS-2级列控系统地面设备的中心、CTCS-3级列控系统地面设备的重要组成部分，列控中心和联锁设备二者间的通信是通过安全数据网实现的，其中主要涉及区间状态、区间方向、车站进路、轨道区段、进站信号机断丝、允许发车、改方状态、信号限速、异物侵限灾害防护、信号状态采集及驱动命令等信息的交换。列控系统与联锁系统将构成列车指挥与控制的综合智能系统。文章针对典型的列控中心系统与联锁间通信故障分析和处理过程，以寻求快速化、规范化方式处理列控中心故障为目的，以列控中心 TCC 设备结构为基础，以分析终端数据为依据，对列控中心系统设计和维护应用中的注意事项进行分析，给出了一个较为行之有效的故障处理办法。%Train control center is the center of CTCS-2 Train Control System Ground equipment,and important part of CTCS-3 train control system ground equipment,the communication between train control center and interlocking equip-ment is realized by safety data network,it mainly contains the exchange of information such as the interval state,interval direction,station access,track section,home signal filament break,train departure permission,state of the direction change,speed limit of signal,disaster protection for the foreign invasion,signal status acquisition and driving etc. inter-locking system will constitute an integrated intelligence system for command and control of the train. During the analysis and treatment of communication failures between the train control center system and interlock,by adopting rapid and normalized processing mode,based on TCC equipment structure of train control centre and terminal data analysis,the matters needing attention in systematic design and maintenance application of train control centre are analyzed and an ef-fective failure treating method is found out.
