摘　　要： 近年来,随着嵌入式技术和网络控制技术的发展,人们开始追逐信息化的舒适生活。而智能家居就是指将各种信息设备通过家庭网络连接起来,从而构建安全、舒适、方便的信息化居住空间。家庭网络监控平台的设计是智能家居系统的关键,基于TCP//IP技术和Browser//Sever架构的监控系统,已经成为一种最普遍的网络信息交互平台。平台借助以太网和Internet技术,把嵌入式系统资源连接到网络上,用户通过浏览器实现对远端设备的监视和控制。 通过对无线组网技术的分析和国内外智能家居系统的研究,本文设计了基于Web技术的无线家居监控系统,研究内容包括: /(1/)传感器终端节点的设计和无线协议的应用层设计,使用CC2430芯片来设计无线传感器节点。 /(2/)家庭网关的搭建。采用ARM7芯片设计家庭网关,考虑到嵌入式uClinux源代码的开放性和网络支持功能,选择uClinux嵌入式操作系统。经过对TCP//IP协议进行裁剪,实现了TCP、IP、ARP、ICMP等协议。 /(3/)系统平台的应用软件开发。选择B//S应用软件开发模式,它由客户端浏览器、Web服务器和数据库服务器三个部分组成。首先将嵌入式Web服务器移植到监控系统中,通过设计简单的HTTP协议来规定Web服务器和浏览器之间的信息传递机制,利用CGI技术开发服务器端应用程序,实现动态交互的需求。 传感器终端节点将采集到的各种环境数据,通过无线方式传送到家庭网关的射频模块。射频模块通过串口与家庭网关主控单元相连,家庭网关通过以太网把数据传送到本地计算机上进行分析。远端用户通过因特网访问本地计算机,实现对现场环境的查询。同样,用户在远端通过调用服务器的CGI程序对现场环境进行监控,并将结果返回远端的浏览器。 In recent years,with the development of embedded technology and network control technology,the informational and comfortable life becomes the object of people. Smart Home aims at constructing safe,comfortable and convenient habitation space, through the network connecting the information equipment.The family network monitoring platform is a key part of the Smart Home system.The control systems based on TCP//IP technology and Browser//Sever architecture,has become one of the most common network platform for information exchanged.The embedded system resource is connected to the network by Ethernet and Internet technology,and the remote equipment is monitored and controlled by the users through the web browser. Through the analysis of the wireless network technology and the research of the intelligent home systems at home and abroad,the wireless home monitoring system based on Web technology is designed in this paper.The research point as follow: /(1/) The designing of sensor node terminals and the application-layer in wireless protocol,the wireless sensor nodes is designed by CC2430 chip. /(2/) The construction of Home Gateway.The embedded gateway platform is based on the ARM7 chip,the embedded operation system is based on the uClinux for its free, open-code and strong network supported characteristic.After the TCP//IP protocol reduced,the protocols of TCP、IP、ARP、ICMP are completed. /(3/) The development of application software in platform.The Browser//Sever application development model which be composed of client browser、Web server and database,is chosen.First of all,the embedded server is transplanted into the monitor system.The transmission mechanism between Web server and browser is provided by designing of the simple HTTP protocol.The dynamic interaction is completed by developing applications in the server with CGI technology. The kinds of environmental information will be collected by sensor nodes,and these data will be sent to the RF module of Home Gateway via wireless
