【摘要】 本文主要探讨因特网的接入技术，并着重讨论了嵌入式因特网接入技术。 随着嵌入式技术的发展和逐渐成熟，各种网上信息产品，如：个人数字助理，电视机顶盒，网络电话，防盗系统等嵌入式系统设备，都要求与Internet联网，把微处理器技术应用到嵌入式Internet系统中将成为今后的发展方向。本课题的目的是对嵌入式因特网接入技术的理论可行性进行详细地分析，并对其应用技术及解决方案进行研究。 本文给出了一种嵌入式接入Internet的具体解决方案，即用8位微控制器与虚拟软件包相结合的方法，来接入到以太网，然后再通过以太网接入到因特网。详细地给出了这种解决方案的软硬件实现方法。在硬件方面，给出了硬件电路的设计原理及各部分电路的具体实现方法和原理图。软件设计中首先给出总的软件流程图，然后给出了具体的协议的实现。 最后给出了实现网页浏览功能和Ethernet／RS232网桥功能的实验线路连接方法及具体实验方案，来证明理论研究的结论。实验结果表明采用8位微控制器与虚拟软件包相结合的方式接入Internet是完全可行的，这将为家电上网，远程控制，远程数据采集等提供一种新的解决方案。更多还原

【Abstract】 In this paper .we mostly discuss the technology of Internet accessing, and discuss emphasizedly the technology of embedded Internet accessing.With the development of embedded technology and its maturation little by little,all kinds of Internet information product,such as personal data assistant,TV Set-Top-Box,Internet phone, guard system and so on,all want to connect with Internet.Using the Micro processer in the embedded Internet system will be the development direction in the future.The destination of this task is to analyze detailedly the theory feasibility of embedded Internet technology.and make research about its application technology and resolvent.This paper gave one kind of resolvent of embedded Interenet accessing,that is the method of combining eight bit micro processer with virtual software package .We use this king of method to access Ethernet ,and then access Internet through Ethernet.Then we gave detailedly the hardware and software reality method of the resolvent.lt not only introduce its hardware development theory ,the reality method of all the circuits, and its theory chart, but also gave its total software flow chart and the reality method of all the protocols needed.At last, we gave the circuit connection method of Web browse function and Ethernet/RS232 gateway function and the detailed resolvent to improve the results of theory research.The result indicates that it is feasible to access Internet with the method of micro controlling unit and virtual software package.This method will provide a new kind of resolvent to appliance accessing Intemet,long-distance controlling and long-distance data collection.更多还原
