【摘要】 车载导航系统结合了导航定位技术、地理信息系统(GIS)、通讯技术以及嵌入式计算机技术，为用户提供导航定位、地理信息等服务。本论文首先讨论了车载导航系统的原理和硬件结构，然后分析设计了软件系统的工作流程及实现方案。 结合课题实际应用，本论文介绍了Windows CE操作系统定制开发的模式，并且具体讨论了实际开发当中遇到的几个技术问题，以及课题中基于windows CE应用程序框架的设计。 电子地图显示系统是车载导航系统软件设计的主体。论文从软件开发的角度，用模块化方法对显示系统的框架结构进行合理划分，并深入讨论了每一个模块的软件设计方法。论文还介绍了当前较流行的电子地图文件格式Shapefile格式，并且讨论了该格式在课题中的相关应用和软件设计。 论文最后介绍了GPS数据处理原理及流程，并从课题实际应用角度深入讨论了各部分的工作。论文还详细介绍了基于Windows CE操作系统下的串口通讯，并讨论了一个同步I／O串口类的具体设计。课题使用D10模块的短消息(SMS)功能实现车载无线通讯，论文对该模块的实际应用和软件开发也进行了相关介绍。更多还原

【Abstract】 Integrating the technology of navigation, Geographic Information System (GIS), communication and embedded computer, vehicle navigation system provides some navigational and geographic information for vehicle driver. In this paper, I introduce firstly the principle and hardware frame of vehicle navigation system in my study task, and then analyze how to develop the software. More deep discussion is invested to each part in the follow chapters.It is the developing mode of Windows CE applied to my study that is reported as the first part. Several technical topics, I have worked on, are specially discussed. At the last of this part, I introduce a new software application framework on Windows CE operating system.The work of electronic map display system is the principal part of the entire software design. From the angle of software development, and base on the display principle in computer, I divide the total system framework into several software modules, so I can settle them respectively. HSRI Shapefile format is currently popular to store electronic map data. The paper introduces it and its application in my study briefly while designing its software model.The last part is the handle of GPS and GSM. I have introduced how to apply GPS data to vehicle navigation. Besides the process theory, all steps are discussed in detail. In the same chapter, I spend several sections on explaining serial communication in Windows CE. As Windows CE operates at seria communication by its synchronous I/O routines, a new C++ class is designed, which is discussed here. To enable vehicle to communicate by wireless, I add the D10 module and make use of its short message service (SMS). All its related application is discussed in the paper.更多还原
