基于ARM的嵌入式CEBus家庭网关设计
|
摘要
随着信息化技术的迅猛发展,为满足人们对家庭自动化的需求,各类家庭网络协议层出不穷。在众多的协议中,消费电子总线(Consumer Electronics Bus,简称CEBus)由于其本身具有的诸多优势,越来越受到人们的重视,应用也日趋广泛,正在逐渐成为最重要的家庭网络标准之一。
Internet技术的兴起,极大地方便了人们的生活,家电融入Internet的需求也越来越迫切。嵌入式Internet是随着计算机网络技术的普及和发展而兴起的一项概念和技术,它通过现有嵌入式系统增加Internet接入模块来扩展其上网的功能。家庭网关是嵌入式Internet技术应用于智能家庭网络的产物,它是一种连接于家庭网络和外部Internet网络之间的嵌入式设备,使得家庭网络能够实现低成本的Internet接入。通过家庭网关人们可以方便地在Internet上从远端对家中的设备进行监控和管理,同时也使得远程设备维护和集成设备管理成为可能,还可以使设备主动地通过Internet获取信息或发送信息,这不仅使人们享受到信息技术给生活带来的便捷和乐趣,还大大地提高了工作效率。
针对上述需求,本文在深入剖析消费总线协议的基础上,结合Internet网络技术以及片上系统技术(SoC)等,设计开发了基于ARM的嵌入式家庭网关。在家庭自动化网络的发展成为必然的情况下,为CEBus网络家电接入Internet,实现远程控制积累了经验,提供了新的思路和方法,同时也为家庭网关的产业化打下了基础。
在设计中采用了三星公司的ARM芯片S3C2410作为网关的主控模块,节省了系统成本和提高系统性能。在双绞线连接模块采用了具有自主知识产权的家庭网络SoC芯片HN600,提高了系统的稳定性,大大降低了家庭网关的成本和应用门槛。通过将嵌入式操作系统ARM-Linux移植到家庭网关硬件平台,为基于ARM-Linux的软件开发打下了良好的基础,提高了软件的设计效率。
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.
