| Summary: | 碩士 === 明志科技大學 === 電子工程研究所 === 101 === This thesis 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 proposed system contains two major parts: Client system and Server system. The main function of Client system: 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; Server system is to receive, store, and deal with mobile data sending from Client system, so that can do geo-fencing and vehicle tracking. For the use of managing mobile data to say, we can assign and response instant condition immediately.
