| 摘 要： | 基于Windows CE操作系统下的GPS导航系统需要实时地接收来自GPS接收机的定位数据,同时对串口进行实时监控并且还可以在前台界面进行一些其他的操作,利用基于多线程的串口通信编程方法可以有效地解决这一问题。介绍了WinCE操作系统的特点、GPS导航系统的特点、多线程技术的基本概念和串口通信编程技术,分析了GPS导航系统的功能和需求,着重阐述了采用多线程的CCom Port类的串口通信方法来获取定位数据的软件设计过程。通过测试,在满足系统实时性要求的同时,避免了资源浪费,提高系统软件的运行效率。

| Abstract: | The GPS navigation system based on Windows CE OS needs not only gaining real-time orientation data from the receiver serial port but also operating other things ,the way that based on the multi-thread and the serial communication programming technology theory can solve this question. This passage mainly introduced the trait of the WinCE OS and GPS navigation,the multithread basic concept and the serial port communication programming technology are introduced ,and the GPS navigation system's function and the... |
