摘要
介绍了GPS接收OEM板的结构组成、工作原理以及与嵌入系统之间的几种硬件接口电路;分析了GPS输出数据的通信标准及其数据帧的接收和参数提取的方法;并用C51和VC++编写了程序代码,实现了对GPS导航信息的接收和参数的提取。
The paper introduces the structure, the working principle of GPS OEM card, and designs the interface circuits and the communication program between embedded system and GPS card. Then it analyzes the communication protocol of GPS＇s output data, and works out a solution to receive data frame and retrieve navigation information from GPS. It finally develops the software to realize the communication and information retrieval using C51 and VC＋＋.
