地铁联锁站数据监测系统设计研究

详细介绍了广州地铁2、8号线联锁站数据监测系统硬件架构的组成,着重阐述了轨道电路及转辙机的电参数测量方案、车地通信发送设备的实际列车识别报文解析方案、轨旁设备指示灯状态监测方案及现场操作员工作站的视频监测方案。该系统实现了信息的实时采集、存储和分析,可获取设备的实时状态;能利用隔离技术获取设备数据,并对这些数据使用数理统计和大数据处理方法进行解析,从而完成数据物理意义的表示。其对故障分析和排查有一定的帮助。该系统还具有良好的可扩展性,已在广州地铁2号线萧岗站试应用,试用效果良好。

On the Design of Interlocking Station Data Monitoring System

The composition of hardware architecture for Guangzhou metro Line 2 and Line 8 interlocking station data monitoring system is introduced,including the electrical parameter measurement scheme for track circuit and point switch,the message parsing scheme for PII equipment,the running status of the wayside ATP receiving antenna and PTI transmitting antenna.Interlocking station data monitoring system is designed to achieve real-time information collection,storage and analysis,obtain equipment real-time status.It can use the isolation technology to obtain equipment data,analyze the data by means of mathematical statistics and large data processing to explain the physical meaning of the data.This system has been applied to Xiaogang Station on Guangzhou metro Line 2 with good performance.
