Study And Implementation Of Vehicle Mobile Terminal Based On ARM

With the development of city and the manifold of vehicles, the security and management of vehicles have become a serious question of society. The market of vehicle position monitor system is very large. Vehicle mobile terminal is a key part of vehicle position monitor system. It is an integrated system based on ARM, GPS and GPRS. This system may dramatically improve the efficiency and security of vehicles, and enhance the capability of traffic.Firstly, an introduction on the significance, development, related technology and application fields of vehicle mobile terminal was introduced in this thesis. Then the principle of vehicle monitor system and the main function of the terminal were described. The design of hardware and software were presented. The application ofμC/OS-Ⅱin the system was demonstrated in the following parts. Finally, the debugging process of the hardware and software were described.In order to improve capability of real time data transmission and reduce cost of the system, the ARM embedded hardware platform, GPRS network as well as real time operating systemμC/OS-Ⅱwere introduced in this thesis. So data transmission becomes much easier and cheaper than it is done by SMS, and the function of system is easily expanded. Vehicle mobile terminal will be applied widely in the fields of police, logistics and bank, and have a promising market in the future.
