【摘要】 近年来,近距离无线传输技术是发展最快、最引人注目的技术,有人曾经预言,未来的世界将是无线世界。目前存在着多种无线技术,如蓝牙、WiFi、UWB和ZigBee等,这些技术各有优点和缺点,传输速率和距离各不相同,也有着不同的功耗,适用于不同领域。ZigBee技术是一种新兴的无线技术,由于其出现较晚,目前应用还不是很广泛,但是ZigBee专注于近距离传输,成本低、进入门槛低,现在已经得到人们越来越多的关注,成为目前无线技术研究的一个新热点。本文详细研究了ZigBee技术的背景、协议构架、网络拓扑实现,并在理论基础上设计实现了ZigBee开发平台,并编写了相应的软件。此平台主要由母板和子板两部分组成,母板采用MSP430F1611作为系统MCU主控芯片,基于CC2420的RF模块做为子板。母板采用RS-232串口总线与PC机相连,对430单片机进行配置;用JTAG进行程序下载和仿真;母板的核心芯片MSP430F1611通过SPI接口与子板的CC2420芯片进行通信;通过LED闪烁标示网络建立的成功与否以及节点加入、脱离网络。在系统软件设计方面,利用现有协议栈、API函数和源代码,编制了SPI接口软件、数据传输程序和系统测试程序以及PC机配置软件等。基于此平台实现了ZigBee的三种拓扑结构:星形、树形和Mesh网络结构。经过单点对单点和星形拓扑结构数据通信的实验和测试,取得了测试结果,证实了该平台满足低功耗、组网快速的要求。更多还原

【Abstract】 In recent years, the wireless transport technology in short distance has become the most amazing one and it is developed in the highest speed. Someone has predicted that the future is a wireless world. The wireless technology that had been invented such as Blue-tooth、WiFi、UWB、ZigBee and etc. Those technologyies have their own advantages and disadvantages, they are different from transport speed、transport distance and power, so they are suit for different fields. The special characters of ZigBee are low velocity、low power、set up easier, it is used between electronic equipments which in short distance、low power and low transport velocity, major in, such as: industry control (auto control equipments、wireless sensor network), medical care (watch、sensor), AI in house (light、water or electricity count and alarm), remote control set for consuming electronic equipment, wireless connection of PC. ZigBee is a kind of new wireless technology. It is not popular because its oldest appearance, but it is becoming popular and a new hot point of wireless research because of its special characters.This paper has designed a platform which could be used to develop with ZigBee and coded a software that accompanies with it , all that depends on the details research of the network technology of ZigBee.There are six chapters in this paper, organized as follows:The first chapter introduces the development direction of wireless network and the research situation in and out of the country, analyzes the meaning and the necessity of the research of ZigBee network.The second chapter introduces the background、the character and the applications of ZigBee, and compares it with other wireless technologies, at the same time, introduces the IEEE 802.15.4 standard, then, there is a deep research on the protocol structure、network configuration、network conjunction、point binding and the mechanism of data transport.更多还原
