基于GIS技术的列车实时监控系统的设计

Design of Real-Time Train Monitoring System Based on GIS Technology

为改善列车实时监控系统定位精度低、响应时间长的问题,研究了以GIS地图高精度轨道坐标信息为基础的列车实时监控系统。利用列车车载设备采集列车状态信息和定位信息,然后将数据上传至GIS轨道数据模块,采用近临法匹配GIS空间地图和GPS终端信息,最后将输出数据传输至地面终端显示与控制模块,实现了列车状态信息和定位信息的实时监控。

To improve the problems of low positioning accuracy and long response time in real-time train monitoring systems,a train real-time monitoring system based on high-precision track coordinate information from GIS maps was studied.Utilize onboard equipment to collect train status and positioning information,then upload the data to the GIS track data module,match the GIS spatial map and GPS terminal information using the proximity method,and finally transmit the output data to the ground terminal display and control module to achieve real-time monitoring of train status and positioning information.
