Based On The Dm9000 Ethernet Controller Network Appliance Control System

21 century is a century of information technology and various telecommunications and the Internet to promote the new technology of the tremendous progress of human civilization. As information technology, computer network technology and the rapid development of widely available, more and more families to the Internet or Intranet access to information and information.Today's network infrastructure has been all over the world, Internet access has not only confined to personal computers and workstations, appliances can be connected to the Internet. This benefit from the latest digital and network technologies, such as air conditioners, refrigerators, televisions, washing machines and other consumer electronic devices, as well as printers and other office equipment have become "networked" equipment, which we call the Network Appliance devices.Against such a backdrop, a network appliance system design programmes, this programme, the use of DM9000 Ethernet controller chip with complete upper SPCE061A network protocols, which constitute a complete network of terminals, allows appliance control variable more convenient.DM9000 is a Chip controlled via Ethernet, it can automatically acquire the IP package with address accordant with the assumed MAC to perform the receiving and sending of the IP package,combined with a SCM to conduct upper protocol, then it composes an integrated network terminal. This Paper stated a general low cost Solution which uses SCM and Ethernet Chip combined with the Internet technology to perform remote monitor of the control system. The real time data collecting is done by Linyang 16 bit SCM on site, uploading to Internet via Ethernet Chip, the Customer Terminal acquires information and perform monitoring by B/S mode. The Web Server is consisted of SPCE061A and DM9000. The main contents are:1. Studied the structure of DM9000 in detail, the sending and receiving method of package and the programming method of Ethernet.2. Analysed the TCP/IP of Ethernet in detail,including a deep study of LwIP protocol shed, analysed the design and realization of LwIP protocol shed. 3. Studied the operation method of Web Server of this System.4. The realization method of the Hardware platform design, Workflow and Software of the network house electric appliance control system based on DM9000 Ethernet Controller.
