嵌入式导航系统网络通信设计实现

Network Communication Technique in the Embedded Navigation System

介绍了嵌入式计算机的特点和一个嵌人式导航计算机系统；重点论述了该导航嵌人式计算机中导航信息高速网络通信协议的设计实现；对该系统的嵌入式结构和硬件特点,利用基于DOS下的socket库；在嵌入式导航计算机硬件环境下,运用TCP／IP协议,设计了导航信息帧格式,并用C／C++编程,实现了DOS平台下网卡稳定、可靠、高速导航信息传输通信。

An embedded computer system is designed for a navigation system. The key problem is to design and realized the high speed network communication for navigation information exchange. According to the characteristics of the system hardware and software environment socket library is adopted based on TCP/IP that facilitates the programming process greatly. And network communication under this PC/ 104 embedded computer is realized in C/C＋＋ code accompanying with the steady and high speed real time exchange of the navigation informarion.
