调度集中系统列车进路预告异常问题分析

Analysis of Abnormal Train Route Advance Notice for Centralized Traffic Control System

调度集中(CTC)系统在分散自律模式下应具备向列车发送进路预告的功能,作用是向司机提供下一站的进路状态信息。为保障列车正常运行,降低多方向车站进路错排的风险,结合典型案例,研究导致列车进路预告异常的原因及解决措施。提出通过扩充CTC系统GSM-R接口服务器基站覆盖列表的方式,来解决列车错误注册基站问题;明晰机车CIR数据模块异常故障现象,降低故障影响范围;强化司机换端时的规范操作,避免因换端导致列车存在多个机车号,影响CTC系统进路预告发送功能。经现场验证,提出的解决措施有效提高了现场设备运维效率,可为解决类似异常问题提供参考。

In the decentralized and autonomous mode,the centralized traffic control(CTC)system should have the function of sending route forecasts to trains,which is to provide the driver with the status information of the next station’s route.In order to ensure the normal operation of the train and reduce the risk of wrong arrangement of multi-directional station routes,combined with typical cases,the causes and solutions of abnormal advance notice of train routes are studied.It is proposed to solve the problem of wrong train registration of base station by expanding the coverage list of GSM-R interface server base station in CTC system.The abnormal fault phenomenon of locomotive CIR data module is clarified,and the influence range of fault is reduced.Strengthening the standardized operation when the driver changes the terminal,and avoiding the existence of multiple locomotive numbers in the train due to the change of the train terminal,which affects the route advance notice sending function of the CTC system.Through field verification,the proposed solutions effectively improve the operation and maintenance efficiency of field equipment,and provide reference for solving similar abnormal problems.
