摘要
为确保列车安全通过既有线临时限速区段,综合应用射频识别、信息处理与控制、无线数据通信、地理信息系统(GIS)等技术,研发铁路既有线临时限速预警控制系统。在既有线临时限速区段前设置带有临时限速信息的射频标签,在机车上安装射频标签车底识别器和临时限速信息预警控制装置等车载设备。当列车接近临时限速区段时,车载设备自动读取和显示射频标签内的临时限速信息,并向列车司机发出临时限速的语音提示;当列车超速时,车载设备自动输出制动控制信号。为临时限速区段设置的限速信息可利用手持机读取和编辑,并通过其内置的无线通信模块传送到临时限速信息管理服务器,在基于GIS的地图上实时显示临时限速区段的设置情况。经实车试验表明,该系统实现了列车接近和通过既有线临时限速区段时地—车之间临时限速信息的实时自动传递和列车限速预警控制,满足设计和应用要求。
Early warning and control techniques on temporary speed limit setting for existing lines are de- veloped with radio frequency identification, information processing and control, wireless data communica- tion and GIS technique to insure train running safely through the temporary speed limit section of existing lines. RFID labels with the information of temporary speed limits are set before the temporary speed limit section of railway existing lines. Locomotives are furnished with RFID labels car identifiers, temporary speed limit control devices and other on-board devices. When trains approach temporary speed limit sec- tion, on-board devices will automatically read and display the information of temporary speed limits in RFID labels, also broadcast voice prompt to driver. On-board devices automatically send brake control sig- nal as the train runs over speed. RFID information can be read and edited by hand-held reader, and trans- ferred to RFID information management server by its built-in wireless communication module. The setting condition of temporary speed limit section is real-time displayed on GIS-based map. Real train test shows that this system has realized the real-time, automatic transfer of ground-train RFID information as well as train early warning and control while trains approaching and running through the temporary speed limit section of existing lines, which meets the design and application requirements.
