ABSTRACT

This paper introduced the improvement and trend of Home Network. After studying the CEBus standard and technology methods of embedded system's Internet accessing, an embedded gateway based on ARM for the Home Network was designed.

In the design, using SoC chip designed for this project to connect CEBus and the home appliances at home helps users control them easily and remotely through the Internet.

INTRODUCTION

With combination of the technology for civil use and the network information technology, the potential market of home network electronic appliances is growing very fast.

Home gateway cannot avoid being the focus of research as it interconnects the home network and Internet.

INTRODUCTIONHome Network Standards

CEBus, short for Consumer Electronic Bus, was published by Electronic Industries Alliance in 1992.this protocol is mainly based on Power Line Carrier Communication technology.

The biggest advantage of choosing this technology is that there is no need to rewire in the house, and home appliance network can easily be achieved without destroying anything in a house.

6


Now the developed products can realize home network by connecting home appliances to the common power line via specific sockets, which is a very convenient way, and can largely reduce various cost of users.

CSMA/CDCR is adopted as the Medium Access Protocol. It distributes resources to the node whose priority is higher when conflicts on network medium appear.

CEBus supports flexible network topology . Devices will not be restricted by space. As long as they have interface modules to relative medium, they can be connected to the network at any place. In the mean time, they respond to broa

dcast on CEBus.

INTRODUCTIONEmbedded Internet Technology

Embedded Internet is a new concept and technology emerging with the development and popularization of computer network technology.

It takes advantage of the embedded system and adds Internet Access Module to expand system's functions.

10


A research on Embedded Internet Access technology will be the infrastructure of the embedded system with network access design, and it is valuable in terms of both technology and economy.

Generally speaking, there are two kinds of solutions to Internet Access for embedded system:

Direct Access Indirect Access

11


Embedded system is designed for application, and choice of Internet access solution depends on practical situation. With respect to intelligent home application, the combination of embedded system and home appliance makes the level of single appliance's automation rise greatly.

HARDWARE DESIGN OF HOME GATEWAY

This home gateway was designed for CEBus home network based on Twisted Pair, which can realize the intercommunication, remote monitor and control on Internet via CEBus.

Home gateway here was used to connect home network, community intelligent network and Internet.

13


Intelligent home appliances can access to Internet and be remotely monitored and controlled via home gateway.

This home gateway owns standard 10Mbps Fast Ethernet Interface, and can connect Internet and the home appliances inside home network fast and reliably with Web browser to provide friendly GUI.

CGI (Common Gateway Interface) is an interface between external application and Web server. External applications conforming to CGI standard can process the input data from the Web browser, and this would help server and client communicate and control each other.

CONCLUSION

This home gateway can interconnect Internet and home network based on CEBus. As it supports HTTP service, users can monitor and control home appliances remotely on Web.

At present, CEBus is one of the most popular home network protocols, and is broadly applied in the field of Home Automation. With its advantages, it has chance to be the leading standard of home network, and our research on it is valuable.
