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.
