This paper describes the system design and implementation of a vehicle management system and covers the following five sections: (1) GPS signal.(2) Microcontroller functions.(3) SD card storage technology with FAT32 file system.Most MCU use FAT16 file system to manage files, but it wastes a lot of memory space when small files are stored to each cluster.Using the FAT32 file system will ensure an efficient use of the memory space.(4) GPRS transmission.(5) Real-time monitoring Server, which is used to monitor vehicles accurately in real-time.The system adopts a web-based solution aimed at gathering the information of vehicle's status and location in real-time.The location information is exposed with geographic coordinates, computed by a GPS processor in vehicle.The processor is embedded in the proposed device, a driving recorder, installed on a vehicle and responsible for transmitting location information to monitoring server.The recorder is a portable, highly accurate, and low powered vehicle tracking device, implemented with TI MSP430F5438 microcontroller.
