【摘要】 车载导航系统是汽车上的嵌入式系统,它可大大方便驾驶,为人们的出行提供各种便捷服务。在世界上,现代车辆导航方面的研究已经具有30多年的历史。它融合了汽车、交通、计算机、通信、系统科学等领域的技术,一直是众多高科技公司、各研究机构和大学研究的热点。课题名称为“基于嵌入式的车载导航系统研究及其软件开发”本课题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。本文主要研究了以下内容:1、对嵌入式系统、车载导航系统的国内外发展现状进行了研究;概述了嵌入式系统的概念、结构及其特点,并根据嵌入式系统的结构特点及设计原则,给出了一般式嵌入式系统设计的关键技术及方法,为下文嵌入式车载导航系统的设计做铺垫。2、根据嵌入式车载导航系统的功能要求,提出了本系统的总体设计方案,并给出了具体的软硬件部分的组成。在本文中使用的目标平台S3C2410是SAMSUNG公司使用ARM920T处理器内核开发的一款嵌入式处理器,无线通讯模块选用西门子公司的GSM/GPRS双频模块MC35i无线模块,采用西门子公司的GERMIN GPS T15接收机实现GPS信息的接收;软件方面,以Windows CE作为操作系统,以微软提供的嵌入式软件开发工具Platform Builder和Embedded Visual C++作为软件平台进行操作系统定制及应用程序开发。3、介绍了嵌入式导航系统软件的开发平台—-嵌入式操作系统,同时详细介绍了本课题选用的Windows CE .NET操作系统,并具体描述了本课题操作系统内核的定制过程。为应用程序的开发打下基础。4、详细介绍了导航系统的应用程序开发,给出定位功能、无线通信等功能具体实现的部分程序段及实验结果。实验结果表明,本系统具有实时性好、稳定性高、体积小、成本低等优点,非常适合应用在汽车中。更多还原

【Abstract】 Vehicle navigation is a embedded system in car, it can bring much more convenience for drivers, and supply people with kinds of advantage services. In the world, the modern vehicle navigation of research already has 30 years of history. It combines automobiles, transport, computer, communications, and systems technology, and other fields of science, it has been a large number of high-tech companies, research institutions and universities on the hot.This paper is described as "Research and software development of the embedded-based intelligent navigation for vehicle ". It is funded by the item of "automobile navigation control multimedia system" in Tianjin and Hebei province. This paper studies the following elements:1. Research on the development status of embedded systems and vehicle-navigation systems at home; Outline the concept, structure and characteristics of embedded System. According to the structural characteristics of embedded system and the design principles, a general embedded system design methodology and the key technology are given, laying the foundation for the design of vehicle navigation systems embedded below.2. In accordance with the functional requirements of embedded vehicle navigation system, the proposed program of the overall design of the system is given, and gives some of the specific hardware and software components. In this paper S3C2410 made by SAMSUNG is used as subject platform , whose processor kenel is the ARM920T processor;the double frenquency module MC35i made by SIEMENS is used as wireless communication module;and GERMIN GPS T15 receiver also made by SIEMENS is used for receiving the information of GPS.For softeware,the operation system is Windows CE,and embedded software development tools- Platform Builder and Embedded Visual C++ provided by Microsoft are used to customize the operation system and develop the application programme.3. Introduce the software development platform of embedded system - Embedded Operating System, at the same time introduce Windows CE. NET operating system used in the topic in detail. Specific topics describe in the operating system kernel customization process. Lay the foundation for the development of application procedure.4. Introduce in detail the application development navigation system and some specific procedures of positioning function, wireless communications, and other functions are given,and the experimental results also are given.更多还原
