【摘要】 随着计算机网络和通讯技术的不断进步，新的理论、标准和技术层出不穷，无线通信从3G网络到无线网络的接入，再到无线局域网IEEE 802．11x，网络变得无处不在，它和我们的生活也越来越密切，它使人们解除电缆的束缚。而在众多的无线网络技术中，基于ZigBee的无线网络技术以低功耗，低成本，低复杂度等特点受到越来越多企业和个人的青睐。ZigBee技术特别适合于数据吞吐量小、网络建设投资少、网络安全要求较高、不便频繁更换电池或充电的场合。预计将在消费类电子设备、家庭智能化、工控、医用设备控制、农业自动化等领域获得广泛应用。本文在对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协议的用于测量温度的无线传感器网络方案，并设计和开发出了相应的无线传感器节点。本方案中使用PIC18F4620微控制芯片和CC2420无线芯片搭建了一个基于ZigBee技术的无线传感器网络。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。更多还原

【Abstract】 With computer networks and communication technology progresses, new theories, standards and technology will be endless. Wireless communication from the 3G wireless communication network to the wireless network access and to the IEEE 802.11x wireless LAN, networks become ubiquitous, and our lives have become closer and closer. It enables people to lift the restraints of cables. In many wireless network technology, wireless network technology based on ZigBee with low power consumption, low cost, low complexity features loved by an increasing number of businesses and individuals of all ages.ZigBee technology is particularly suited to small data throughput and network construction investment, the higher requirements of the network security, inconvenience frequent battery replacement or recharging occasions. Expected to be in consumer electronics equipment, intelligent household, industrial, medical equipment control, agricultural automation fields of application.In this paper, on the basis of the wireless sensor network protocol analysis technology, a method is proposed for measuring the temperature of wireless sensor networks, and the design and development of the corresponding wireless sensor nodes. The program is the use of microchip PIC18F4620 and CC2420 and built on a ZigBee technologies wireless sensor networks. The network acts as a coordinating center for a number of nodes and terminal nodes together to form a star network. Coordination is responsible for the inquiries to the terminal node temperature information, terminal nodes will be responsible for the temperature sensors to collect information and feedback to the coordinator, so as to achieve a regional temperature monitoring purpose.更多还原
