Design Of Embedded Home Network Gateway For CEBus Based On ARM

Along with the rapid development of information technology and to satisfy the damands of the need of home automation, lots of home network protocols emerge in endlessly.Among these protocols, CEBus, which is short for Consumer Electronics Bus, has gained more and more attention and been used widely with its advantages. So CEBus has been one of the most important home network protocols.With the Internet technology, people's life has been convenient and the need for connecting the home appliances with internet has also been more and more urgent. The embedded Internet technology is a new concept developed with computer network technology. The embedded system can be added the Internet interface module to expand its Internet function. Home network gateway is the production of embedded Internet technology applied on Home network, which connects Home Network and Internet in low cost. With the home network gateway, people can control and manage the electric appliance remotely and easily through Internet. That can let people enjoy the conveniences brought by information technology and increase the work efficiency greatly.To satisfy these needs, after analyzing the protocol of CEBus and combining Internet and SoC technology, an embedded home network gateway for CEBus Based on ARM was designed. That brought forward a new method for CEBus connecting to Internet and made a good foundation for industrialization of this gateway.In the design, ARM chip S3C2410 produced by Samsung was selected as the main control module of the gateway, which saved cost and increased the performance of the whole system. In the twisted pair communication module, the SoC chip HN600 whose Intellectual Property owned by our team was used to improve the system stability and cut cost and application threshold greatly. Through porting embedded operating system ARM-Linux to hardware platform of the gateway, a good foundation was made for software design and increased the design efficiency.
