The Technology Of Embedded Internet Accessing And The Research Of Its Applications

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.
