Firstly, introduce the vehicle management system, which is mainly developed for units to manage vehicles. The system mainly includes a vehicle management module, a terminal device management module, a query and statistics submodule, and a system maintenance submodule. Among them, the vehicle management module mainly focuses on vehicle management, and the vehicle management module mainly includes vehicle information; Terminal device management module, which queries vehicle status information based on terminal information, etc; The query statistics sub module can collect ACC information, mileage information, etc. of the target vehicle.

　　Therefore, the vehicle management system is actually a component of software, also known as vehicle management software, vehicle management platform, etc. Compared with the in car GPS positioning system, this system is more complex and can be understood as a system consisting of multiple components, including the vehicle management system listed above, as well as the IoT card communication system and hardware terminals, all of which are combined to form the in car GPS positioning system.

　　The IoT card communication system mainly refers to SIM flow cards. Different devices require different formats and flow cards, and special attention should be paid when using them to ensure sufficient flow and prevent downtime. GPS hardware terminals, commonly known as GPS, are basically divided into three types: wired type, OBD interface type, and strong magnetic non installation type. It can definitely be subdivided, so we won't explain it here.
