w 摘 要 近年来人们对生活环境智能、舒适、安全要求越来越高，并伴随着计算机技术、通信技术的发展，智能家居便应运而生。然而随着智能家居的发展，所需要环境监测数据变越来越多，这就需要一种安装便捷，实用并且价格合适产品出现。有线传感器系统需要大量的布线，安装费用高的同时维护也很不方便，并且在一些建筑物中无法布线。随着物联网的发展，zigbee渐渐走入人们的视野。Zigbee低功耗、低成本、低速率的短距离的优点。Zigbee组成的无线传感器网络具有维护成本低、组网灵活、部署方便的特点，仿佛是为了无线智能家具而生的。将zigbee技术与智能家具结合有很好的应用前景。基于此本文选择了zigbee无线通信技术来组件无线智能家具网络。本文组织结构如下： 首先，分析了智能家居的发展、以及无线传感器网络的发展，结合智能楼宇的特点，讨论了无线传感器网络在智能家居中应用的优越性。然后介绍zigbee技术，深入研究ZigBee 协议各个通信协议层的结构与功能，在此基础上，选择采用ZigBee 星型网络拓扑模型实现智能楼宇传感器网络系统。 然后介绍本设计采用的硬件，硬件采用无线龙ZigBee开发套件。ZigBee网络无线传感器节点采用低功耗微控制器CC2530，节点采用96X16液晶显示，USB接口，电池供电，具有经济、高效、方便、快捷、可视性、并可重复使用。软件方面，根据Zigbee联盟制定的标准，利用德州仪器(TI)推出业界领先的ZigBee协议栈(Z-Stack)。Z-Stack装载在一个基于IAR开发环境的工程里。 经测试，本文的无线节点数据传输可靠，通讯距离满足需求；节点能量消耗少、估算电池使用寿命长，设计实现了能长时间工作的智能楼宇环境监测系统，具有智能化、低成本、低功耗的特点，同时对ZigBee 的其它扩展应用具有参考价值。 关键词：环境监测，智能楼宇，无线传感器网络，ZigBee，CC2530 ABSTRACT In recent years, pepole more and more like a living environment more smart, comfortable, safety and accompanied by the development of computer technology, communication technology, intelligent home have come into being. With the development of the intelligent home, however, the required environmental monitoring data become more and more, which requires an easy to install, practical, and the price is right product. Wired sensor system requires a lot of wiring, installation costs, while maintenance is also very convenient, and in some buildings can not be wiring. With the development of Internet of Things, the zigbee getting into peoples vision. Zigbee is low power, low cost, low-rate short-range . Zigbee wireless sensor networks have to maintain a low cost, flexible networking, and easily deployable, as if born to wireless smart furniture. Zigbee technology and intelligent furniture combined with a good application prospect. Then, this article select zigbee wireless communication technology to the components of wireless smart furniture network. The paper is organized as follows: First of all, thisi article describe the development of the smart home, as well as th
