嵌入式系统的Internet接入实现

Internet Access of Embedded System

介绍了嵌入式Internet的概念和嵌入式系统的Internet接入实现方案,讲述了在微控制器MCU中实现嵌入式WebServer的方法。在分析嵌入式Web服务器有限状态机基础上,用原始套接字编程的方法实现了thin-TCP/IP协议,并且对嵌入式系统应用层协议进行了设计,简化的协议降低了系统硬件的要求。集成这两种协议的浏览器可访问嵌入式WebServer,并通过提交表格的方式向嵌入式WebServer输入控制信息,在工业自动化和消费电子行业有广泛应用前景。

This paper presents the concept of Embedded Internet,and the methods of accessing the Internet for Embedded System.And introduces how to integrate Embedded Web Server into a micro controller (MCU).After analysis of the Finite State Machine(FWS) in Embedded Web Server, thin-TCP/IP is implemented by raw socket,and the application layer protocols are designed for Embedded System.
