地铁ATS日志解析工具的开发和应用

Development and Application of ATS Log Analysis Tool for Metro Signal System

目前国内地铁广播系统(PA)和乘客信息系统(PIS)都是通过接收信号系统ATS(自动列车监控)信息,解析后触发列车预到站和到站广播、PIS屏进到站信息显示。当发生列车进到站广播播放或PIS屏显示和实际列车运行情况不一致时,如果确认通信系统硬件设备无故障,可对ATS发送给广播系统和PIS系统的日志进行解析,进而快速定位是ATS信息问题还是广播系统和PIS系统接口程序解析日志问题。基于ATS系统和广播系统、PIS系统接口协议,利用VBA语言编写ATS日志自动化解析工具,通过解析ATS发送给广播系统、PIS系统的日志,详细显示解析结果,辅助一线人员进行故障定位和处理。

At present,Public address system(PA)and passenger information system(PIS)of domestic metro lines and communication specialty all receive the information of ATS(automatic train control)signal system,analyze and trigger the train pre arrival and train arrival broadcasting,PIS screen arrival information display.When the broadcasting or PIS screen display of the train arriving at the station is inconsistent with the actual train operation,if it is confirmed that the hardware equipment of the communication system has no fault,the log sent by ATS to Public address system and PIS system can be analyzed,so as to quickly locate whether it is the problem of ATS information or the problem of log analysis by the interface program between Public address system and PIS system.Based on the interface protocol between ATS system,Public address system and PIS system,this paper uses VBA(Visual Basic for applications)computer language to write an automatic analysis tool for ATS log.By analyzing the logs sent by ATS to Public address system and PIS system,the analysis results are displayed in detail to assist front-line personnel in fault location and processing.
