Abstract: In order to realize the real-time monitoring of vehicle status and position, query the vehicle historical data and track, and get rid of regional restrictions, a remote monitoring system for vehicles based on a cloud platform is designed. The system includes vehicle terminal and cloud service platform, which the former is responsible for collecting vehicle status data and GPS longitude and latitude, and uploading them to the cloud through 4G network. The cloud service platform includes visual monitoring center, database, and web server. The system administrator carries out real-time remote monitoring and data query on the vehicle through the cloud monitoring center, and the ordinary users monitor vehicles through the web browser, forming a two-level supervision mode. The results of long-term operation show that the system is stable and reliable, and can realize remote monitoring in different places. The monitoring data is rich, and the data refresh frequency is about 0.62 Hz. Therefore, the system has good real-time performance and can query the historical data and historical track of vehicles.
