Based On ARM9 Automobile Multimedia System Design And Exploitation

Automobile Multimedia system is advanced science and technology system that is integrated by some technics such as GPS, GIS, database, Multimedia, communication and embedded .The System can be used to provide some important information for driver real-time and effectively. The paper is funded by the item of"automobile navigation control multimedia system"in Tianjing and Hebei province . The system hardware is based on ARM9 embedded board , and the system software is based on the tool of PB and EVC ++ which was provided by Microsoft. Our task is to implement these functions by software programming when all hardwares are chose and connected. What followed are the main contents:Firstly, the paper induce between embedded system and embedded operating system including definition, character, category, relation and so on .Following automobile multimedia system's development trend, the actuality of our nation's market and the requirement and the exception, and fulfilled the kernel of operating system.Secondly, the design of system's wireless communication module. These functions of automobile multimedia system include automobile navigation system, MP3 player, sending short message. an all-around solution to the problem is proposed in this paper, which integrates these functions by embedded system.Finally, the automobile navigation E-GIS system is an important part in this design. This paper investigates GPS location, GIS navigation and description methods and data structure of navigation E-GIS. The objective of this paper is to implant the basal functions of the automobile navigation system detailedly.In a word, this automobile multimedia system obtained expectant result by practical running, fulfilled the design's purpose. Sum-up of this system's characters is made.
