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.

INTRODUCTION
Home 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.
5
INTRODUCTION
Home Network Standards

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.

INTRODUCTION
Home Network Standards

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
broadcast on CEBus.

INTRODUCTION
Embedded 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.

INTRODUCTION
Embedded Internet Technology

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

INTRODUCTION
Embedded Internet Technology

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.
12
HARDWARE DESIGN OF HOME GATEWAY

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.

SOFTWARE DESIGN OF HOME GATEWAY

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.
