Research On The Key Technologies Of Integration Vehicle Management And Control System Based On Bluetooth

With the quick development of economy, our life are becoming better and better. The quantity of vehicle is also increasing quickly. How to manage vehicle effectively becomes very important. On the other hand communication and information technologies are developing very quickly, it is possible now to bring up a new and powerful vehicle management and control system. The main task of the thesis is to develop an integration vehicle management and control system, which can not only deal with the manage problem, but also has functions of monitor, auto payment, internal communication of a motorcade, guarding against theft and so on.In the first chapter, the background of the project is introduced and the current status of vehicle management is described. After comparing Bluetooth with Radio Frequency Identification (RFID) technology, why Bluetooth is used in realization of the system is explained.Then three layers of specification of Bluetooth are introduced, which are Radio Specification, RFCOMM protocol, and security protocol. These layers have direct relation with our integration vehicle management and control system.In chapter 3, the characteristics and difficulties of Ad hoc network are discussed. A routing protocol is provided for the Ad hoc network based on Bluetooth.The realization of management and control system of vehicle are emphasized in chapter 4, 5, 6 and 7. After the functions of this system are discussed details, a detailed configuration and flowchart of system are given. The hardware of vehicle card is designed and developed. And then two products developed by the team including writer are presented respectively, which one is the Army Vehicle Management and Control System, and the other is the Post Vehicle Management Information System. At last chapter, the design and development of the Bluetooth modules of 100 mW of maximal power are discussed and they are largely used in the systems.
