The Design And Realization Of Embedded Appliance Controllers Based On Internet.

With the development of electronic techniques and computer network tech-niques, embedded system has been widely used at home and industry in various fields. Consequently, it is far more used in info household appliances, network equipments and industry-controlling fields than in computers. However, most embedded systems are still applied separately. Usually network can be organized by RS232,RS485,CAN and so on in order to achieve the informational share and communication among the different embedded equipments. Unfortunately, their valid radius is shorter and they go beyond the Internet. If the embedded equipments can be connected with Internet, that will be convenient for us to realize the informational share with less money and control from far away. Therefore, it is very important to research and apply the embedded Internet technique.TCP/IP Protocol which is the base of Internet is one of the stable network protocol. The present researcher mainly analyses ARP,IP,UDP,TCP,ICMP and HTTP in this thesis.The researcher shows the feasibility of TCP/IP in embedded system. An embedded server can be designed based on the TCP/IP. First, using Embedded Web Server, clients can aquire the current working state and some parameters of household appliances ,secondly can control household appliances remotely.
