Design And Implementation Of Vehicle-mounted Application System Based On Bluetooth Module

The vigorous development of automotive electronics drives the vehicle-mounted system gradually becoming cars’ standard equipment. As the consumer demand is improving by degrees, the vehicle-mounted system progresses persistently towards the direction of safety, intelligence and comfort. Nowadays, the market of the vehicle-mounted system is facing a strong competition, and system manufacturers are eager to enhance the competitiveness of their products. On the basis of the old system, the thesis aims to design and implement the new vehicle-mounted application system which is based on the bluetooth module and is added with new functions and optimized performances.The main content of this thesis include:(1) The related techniques are analyzed, including Bluetooth, the application framework of PureMVC, the multiplexing protocol and the SQLite database.(2) The existing defects of the legacy system are analyzed and the improvement methods adopted by the new system are raised. The system requirement analysis is conducted from two aspects of function and performance, and then the collectivity design which consists of hierarchical structure design and functional structure design is handled according to above demands.(3) Such issues are designed in detail as the implanting process of PureMVC, the method for handling of Bluetooth communication protocols, the strategy of data synchronization and storage as well as the strategy for the application of human-computer interaction approaches. The main functions of the system are also implemented.The test result verifies the accuracy of the vehicle-mounted application system in respects of function and performance and satisfies the system requirements. Through reasonable design and implementation, the system improves the user experience, minimizes the user’s distractions during the drive and enhances safety and convenience for driving eventually.
