CTCS3-300H型列控车载设备状态在线监测与智能分析系统开发与应用

Development and application of online status monitoring and intelligent analysis system for onboard equipment of CTCS3-300H

针对CTCS3-300H型列控车载设备(简称:列控车载设备)各单元运行日志数据分散存储、数据转储下载接口多、数据分析工作繁琐耗时的问题,根据列控车载设备结构特点,设计了列控车载设备状态在线监测及智能分析系统。该系统统一了列控车载设备各单元的日志数据采集与传输接口,借助既有的车地无线传输通道,设计了灵活、务实的车地数据传输方案,实现了用于列控车载设备状态在线监测的事件通告报文的实时传输,提供故障日志自动下载、手动按需下载两种日志数据无线下载方式,在满足列控车载设备状态在线监测和故障分析需要的前提下,最大限度地减少车地数据传输量。通过有效利用列控车载设备日志数据进行智能分析,能够快速、准确定位故障原因,实现故障自动报警并给出处置建议,提高了列控车载设备故障应急处置和维护效率,为动车组安全运行提供强有力的技术保障。

To deal with the issues of scattered storage of operation log data in each unit,multiple data dump and download interfaces,and tedious and time-consuming data analysis work of the on-board equipment of CTCS3-300H train control system,the online status monitoring and intelligent analysis system for CTCS3-300H onboard equipment is designed based on the structural characteristics of the equipment.The system unifies the collection and transmission interfaces of log data for each unit of the train control on-board equipment.By use of existing train-ground wireless transmission channel,a flexible and practical train-ground data transmission scheme is designed to achieve real-time transmission of event notification message for online monitoring of train control on-board equipment status as well as two wireless download methods for fault logs:automatic download and manual on-demand download.While meeting the needs of online monitoring and fault analysis of train control on-board equipment status,the transmission volume of train ground data is minimized.By effectively utilizing the log data of train control on-board equipment for intelligent analysis,it is possible to quickly and accurately locate the cause of faults,achieve automatic fault alarms and provide fault disposal suggestions,improve the efficiency of fault emergency response and maintenance of train control on-board equipment,and provide strong technical support for the safe operation of high-speed trains.
