基于ZigBee技术的无线传感器网络系统研究
摘要
随着信息技术的发展,人们对无线通信技术的要求日益提高。传统的无线通信技术Wi-Fi、超宽带通信UWB、近场通信NFC、蓝牙、红外无线数据通信(IrDA)等技术,已经不能满足当今对无线应用的需求。尤其是物联网技术的提出,需要传感器网络具有低速率、低功耗、低成本、自组网能力强等特点,并且在恶劣的自然环境下也能正常工作。ZigBee技术就是在这样的历史背景下应运而生。ZigBee技术是一种新兴的短距离、低速率无线网络技术,是一种介于无线标识技术和蓝牙之间的技术提案,主要用于近距离无线连接,其优良的自组网性能和网络的健壮性整体的网络协调性等都是其它无线技术无法比拟的。
本设计是基于ZigBee技术开发的一套无线传感网络模拟装置。该装置采用射频性能优良的Ti (Texas Instruments)2430芯片作为核心的控制模块,使用高效的IAR集成开发环境作为软件平台,显示模块采用HS12232-9 LCD液晶屏显示模块,上位机可通过PC串口管理全网的数据和命令的收发。,界面友好,使用方便。当数据的在ZigBee网络中传播时,可以在PC机上使用Packed Sniffer等抓包软件捕获网络中的数据,进行研究和分析。
本模拟装置的功能实现比较完善,网络协调性较好。可以按照组网要求发送和接收数据,并将数据和命令清楚的显示在LCD液晶屏上,且数据也能够及时的上传给上位机,供管理和使用人员参考和调试。

Abstract
With the development of information technology, the increasing demand for munications technology. The munications technology Wi-Fi, ultra-munications UWB, Near munication the NFC, Bluetooth, infrared wireless munications (IrDA) technology, can no longer meet today's demand for wireless applications. Especially the of Things technology, the need to works with low-rate, low power, low cost, since working ability and other characteristics, and in the harsh natural environment can work properly. ZigBee technology is against this historical background, came into being. ZigBee technology is an emerging short-range, low-rate work technology is a cross between a wireless identification technology and Bluetooth technology proposals, mainly for short-range wireless connections, work performance work the robustness of the work coordination are other wireless technologies can not match.
The design is based on ZigBee technology developed by a wireless work simulator. The device uses the excellent RF performance of Ti (Texas Instruments) 2430 chip as the core of the control module, the use of efficient IAR Integrated Development Environment software platform, the display module HS12232-9 LCD LCD screen display module, the puter through the PC serial port manage the work to send and receive
