摘　　要：提出一种嵌入式Internet的接入方案,即采用ATmega128和RTL8019AS作为主通信模块,在ATmega128中内嵌Nut/OS操作系统和Nut/Net协议栈,从而能够更加方便快捷地实现远程数据采集、监控、诊断等功能.详细阐述了TCP/IP协议栈的组成,讨论了芯片和嵌入式操作系统的选择,给出了软硬件的设计方案,并简单介绍了一个远程通信试验.With the great development of interact and electronic information technology, networking has been a new trend of embedded system. In this article, a way to communicate embedded system with internet is proposed, which is, to make use of ATmega128 and RTL8019AS as the main communication modules, and to embed Nut/OS and Nut/Net protocol stack into ATmega128, so that we can capture data remotely and make the embedded system remote monitored or diagnosed more easily and efficiently. The article describes the component of TCP/IP protocol stack detailed, discusses how to choose the chips and embedded OS, proposes the designs of the software and hardware, and simply introduces a remote communication test.
