Abstract: An automobile remote monitoring system based on a cloud platform is designed in order to realize the real-time monitoring of the driving status and position of multiple vehicles. The system mainly includes an on-board terminal and cloud service platform. The on-board terminal collects the vehicle status data from the vehicle OBD diagnostic interface and position data through the GPS module, then transmits this data to the cloud service platform by the 4G communication module. The cloud service platform composed of a monitoring center, database, and web server is designed. The monitoring center receives, displays the data sent by the on-board terminal, and stores it in the database. The web side monitors the vehicle remotely and in real-time through the browser. The long-time operation results of the system show that the monitoring center can stably monitor multiple vehicles remotely, providing accurate location data with a map refresh rate of approximately 1.8 Hz and access to the historical track and other data. The web side can remotely monitor individual vehicles with a data refresh rate of 1 Hz.
