摘要
随着科技的发展和人民生活水平的提高,智能家居系统成为了世界范围内的一个热门研究领域。
     智能家居系统是由智能家居安防系统、网络服务系统和家庭自动化系统等子系统组成的家庭综合服务与管理集成系统。其中,智能家居安防系统担负着保护人们生命财产安全的职责,因此成为智能家居系统的首选组成部分。
     论文采用了一种“系统控制中心+ZigBee无线传感器网络”的方案对系统进行了总体设计。介绍了方案的总体框架,并对系统各组成部分进行了详细的阐述。
     系统采用ZigBee技术构建家庭监控网络,并设计了ZigBee网络节点的应用程序。系统控制中心以PXA270为处理器,通过与之相连接的ZigBee模块,接收家庭内部网络采集到的报警信息;再通过GPRS模块以短信或彩信的形式实现报警及控制信息的远程传输。
     本文提出的智能家居安防系统,采用功能强大的PXA270作为系统控制中心控制器,并提供多种接口,方便用户扩展;采用ZigBee传感器网络用于监测家居环境安全并与各种传感器终端节点连接,方便地实现数据的远程传输,而且大大地节省了数据传输的成本。
With the development of science and technology and the improvement of people's lives, Intelligent Home System is becoming a hot research field in worldwide.
     Intelligent Home System is an integrated family service and management system which include intelligent home system of security and defense, network services and home automation systems. The intelligent home system of security and defense assumed responsibility of protecting people's lives and property. Consequently it was an important part of Intelligent Home System.
     A solution of intelligent home system of security and defense, "system control center+ ZigBee wireless sensor networks" is proposed. The general framework of the system is introduced and components of the system in detail are discussed.
     The ZigBee technology is used to build home monitoring network in intelligent home system of security and defense, and the ZigBee network nodes are designed. Through ZigBee module connected, System Control Center for the PXA270 processors receives the family network to alter information collected, and through GPRS to SMS or MMS module alarm and control information of the long-distance transmission is achieved.
     In this paper, intelligent home system of security and defense used powerful PXA270 system as a control center controller and provided a wide range of interface, user-friendly expansion. ZigBee sensor network is devoted to monitoring the home safety and the home environment. It is used to monitoring all kinds of sensor nodes at home which are connected terminals for long-distance data transmission and the cost of data transmission are saved.
