基于ZigBee的温度测量网络硬件设计 [摘 要]本文介绍一种新兴的低功耗、低成本、低复杂度的无线网络技术ZigBee技术及其在无线传感器网络中的应用。无线传感器网络因其在生产生活中将产生的意义重大而受到越来越多的关注。 该系统采用了星型网络拓扑结构。主要工作包括：组建ZigBee无线网络；实现数据的无线双向传输；设计温度控制系统；液晶的显示输出。 无线传感器及其网络协议技术分析的基础上，提出了一种基于ZigBee协议用于测量温度的无线传感器网络方案，并设计相应的无线传感器节点。该网络由一个协调器充当中心节点和若干个终端节点一起，构成一个星型网络。协调器负责向终端节点查询温度信息，终端节点负责将温度传感器所采集到的信息反馈给协调器，从而达到对一块区域进行温度监控的目的。 [关键词] ZigBee；无线通信；温度传感器；网络拓扑结构 Hardware Design of Temperature Measurement Network Based on ZigBee Electronic Information Engineering Major ZHAO Bao-sheng Abstract: This paper presents a new low-power, low cost, low complexity of wireless network technology that is ZigBee Technology and its application in wireless sensor networks. Wireless sensor networks will be given more and more attention for its significance in the production life. The system uses a star network topology. Its main tasks are set up ZigBee wireless network, achieve wireless two-way transmission of data, design temperature control systems, and output the liquid crystal display. Wireless sensor and network protocol are based on technical analysis and proposed a wireless sensor networking program to measure the temperature which based on a ZigBee protocol, and designed the relevant wireless sensor nodes. A coordinator acts as the central node and together with number of terminal nodes to form a star network. Coordinator is responsible for checking the temperature information terminal node; terminal node is responsible for feedback the collected information from temperature sensor to the coordinator, thereby, to achieve the purpose of monitoring the temperature of one region.
