A Study & Implement On The Application Of Embedded Internet Technology In Information Appliance

With the popularization of the Internet technology, the application of Internet has also been in people's daily life deeply. The participant to access the Internet has also been changed accordingly. With the exception of common computer that have already connected into Internet, a great deal of electric instruments began to access Internet. The technology which enable a device connecting into Internet is called Embedded Internet Technology, the goal of the technology itself is to solve the problem that how can a device have the ability to access or to be accessed in internet network. Recently, the study on embedded Internet has arisen close focus of academe; it has been a new studying hotspot in information science area.Many common MCU have been widely used in home appliance by reason of their inherent character, such as: low price, small size and etc. It will drastically promote the process of home appliance's accessing Internet if Embedded Internet Technology can be successfully implemented on it. However, it is the significant key that how to over come the actual difficult since all MCU have their restriction in storage memory and perform speed. So it has been one of the main obstacles for a long time in the way to lead the home appliance into Internet Network. The traditional solution that called EMIT (Embedded Micro Internet Technology) for this issue is to adopt a PC as transitional gateway. The basic implement idea is: TCP/IP and server program run on the gateway, client user access the Internet through the gateway. The method has its inherent defect for their high additional cost and hard to manipulate when used in home appliance. In this dissertation, the Embedded Internet's implement in home appliance has been studied based on the actual facts. The main work in the thesis is as following: The theoretic foundation and trend of Embedded System has been summarized. The current development & foreground of the Information Appliance has been discussed. The implement method of Embedded Internet has been studied. At first, the author analyzed the traditional EMIT and pointed out its defect in home appliance, and then a new method named EMWC (Embedded Micro Web Controller) was put forward to solve the problem based on the Embedded System Theory.A practical Embedded Micro Web Controller model has been designed based on the above theory. From hardware designing to program coding, a micro web controller for simulating home appliance condition has been designed and then Internet network function has been fulfilled on it. At the end of this paper, a lot of repeated experiments and tests were done to...
