【摘要】 汽车多媒体系统是由全球卫星定位技术、地理信息技术、数据库技术、多媒体技术、现代通信技术和嵌入式计算机系统综合在一起的高科技系统,能够实时、高效地向驾驶员提供多种重要信息。课题名称为“汽车导航控制多媒体系统”,由天津市科技发展计划项目和河北省中小企业创新基金支持。本文以基于ARM9的嵌入式开发板为硬件平台、以微软提供的嵌入式软件开发工具PB和EVC++为软件平台展开了课题的研究,本文主要研究内容如下:首先,面对目前发展起来的各式各样的嵌入式技术,很少有专门的文章对其进行归类、总结。所以本文针对这种情况,详细的介绍了嵌入式系统的定义、分类、特点、应用范围以及伴随嵌入式系统而发展起来的嵌入式操作系统的选择方法和依据,并完成了Windows CE操作系统内核的定制工作。其次,系统无线通讯模块设计。本文利用当前嵌入式技术和全球移动通讯技术,把GSM手机模块和嵌入式系统平台相结合,即ARM与GSM兼容,实现汽车多媒体系统无线通讯模块的软件设计部分。主要功能有拨打电话、收发短信等。所有功能一改以往的独立控制,嵌入式技术集这些功能为一体。最后,汽车多媒体地理信息系统设计。本文深入讨论了车载定位导航技术的理论基础,即全球定位系统GPS与嵌入式地理信息系统GIS的集成,以及嵌入式GIS的表达方式和数据结构,并从软件上实现车载导航的基本功能。实验结果表明系统实时性好、稳定性高、体积小、成本低等特点。非常适合应用在现代汽车多媒体系统中。更多还原

【Abstract】 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.更多还原
