摘要
针对轨道交通领域的列车运行安全问题,设计一种基于NB-IoT的地铁列车定位系统。定位终端利用NB-IoT与4G基站建立连接,将采集的定位信息通过云服务器转发至控制中心设备,完成数据处理后,转换成便于调度员识别的位置信息显示出来。测试结果表明,调度员通过列车定位系统,可实时观测到列车所处的当前位置,为地铁列车运行的安全性提供保障。
Aiming at the problem of train operation safety in the field of rail transit,a subway train positioning system based on NB-IoT is designed in this paper.The positioning terminal uses NB-IoT to establish a connection with the 4G base station.The cloud server forwards the collected positioning information to the control center equipment.After processing,the data is converted into location information that is easy for the dispatcher to identify and displayed on the LCD.The test results show that the train dispatcher can observe the current position of the train in real time through the train positioning system,which provides guarantee for the safety of subway train operation.
