Abstract: Qingdao Metro Line 11 uses an automatic train monitoring system (ATS) developed independently  in China. As an implementation platform of comprehensive information monitoring system, the ATS system takes the communication front-end processor as the communication hub, interfacing with clock systems, passenger information systems, broadcast systems, integrated monitoring systems, wireless systems, etc. Now combined with the actual operating data on site, the UltraEdit text editing tool is used to retrieve and analyze the logs of the communication front-end processor. Through the log analysis in the background of the system, it is convenient for the signal maintenance personnel to diagnose the equipment failure point in the future.

Key words: automatic train monitoring system, front equipment porcessor, interface logs, analysis

摘要： 青岛地铁11号线采用的是国内自主研发的自动列车监控系统(ATS)，ATS系统作为一个综合信息监控系统的实现平台，以通信前置机作为通信枢纽，与时钟系统、乘客信息系统、广播系统、综合监控系统、无线系统等实现接口。现结合现场实际运行数据，采用UltraEdit文本编辑工具对通信前置机的日志进行检索、分析，通过系统后台的日志分析，便于日后信号维护人员对设备故障点的诊断。
