摘要
随着科学技术的发展，智能家居生活也渐渐成为趋势。本文设计了一个智能家居系统，采用ZigBee组网、Wi-Fi无线通信技术及嵌入式的网关服务器，实现了家居安防和家居远程控制。系统以 Android 智能设备作为主控制器终端，以三星公司的S5PV210芯片和相关的一些外围器件组建成整个系统的家庭网关控制平台，基于嵌入式Linux操作系统通过Qt设计开发了智能管家软件，而家居内部控制网络则利用ZigBee无线网络技术来实现。智能家居系统通过物联网技术将家中的各种设备（如照明系统、窗帘控制、安防系统、烟雾报警系统、智能厨房、智能洗浴等）连接到一起，提供家电控制、照明控制、窗帘控制、电话远程控制、室内外遥控、防盗报警、红外转发以及可编程定时控制等多种功能和手段。帮助家庭与外部保持信息交流畅通，优化人们的生活方式，帮助人们有效安排时间，增强家居生活的安全性，甚至为各种能源费用节约资金。

Abstract
With the development of science and technology, intelligent household life is becoming a trend. This paper designed a smart home system, USES the ZigBee network, wi-fi wireless communication technology and embedded gateway server, home security and home remote control is realized. System to Android intelligent terminal equipment as the main controller, with samsung S5PV210 some chips and related peripheral devices to form into the family gateway control platform of the whole system, based on embedded Linux operating system by Qt intelligent housekeeping software is designed and developed, while home internal control network using ZigBee wireless network technology to realize.Smart home system in the home through the Internet of things technology with the equipment (such as lighting, curtain control, security system, smoke alarm system, intelligent kitchen, intelligent bath, etc.) together, provide electrical appliances, lighting, curtain control, indoor and outdoor, telephone remote control remote control, anti-theft alarm, infrared forward and programmable timing control and other functions and means. To help families keep smooth communication with external, optimize people's life style, help people to arrange time effectively, enhance the security of home life, even for a variety of energy cost savings.
