1、畢業(yè)設(shè)計(jì)題目:基于ZigBee的環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)學(xué)生:焦艷學(xué)號:20110311102院(系):職業(yè)教育師范學(xué)院專業(yè):電子信息工程指導(dǎo)教師:李頎2015年06月02日基于ZigBee的環(huán)境監(jiān)控系統(tǒng)設(shè)計(jì)摘要無線傳感器網(wǎng)絡(luò)是當(dāng)今國際備受關(guān)注的前沿?zé)狳c(diǎn)領(lǐng)域,被評為未來高科技的三大產(chǎn)業(yè)之一。無線傳感器網(wǎng)絡(luò)是由大量分布的不同規(guī)格和功能的具有感知、計(jì)算和通信能力的微型傳感器節(jié)點(diǎn)通過自組織的方式構(gòu)成的一個(gè)以數(shù)據(jù)為中心的無線網(wǎng)絡(luò)。大量傳感器節(jié)點(diǎn)通過相互之間的分工協(xié)作,可實(shí)時(shí)感知、監(jiān)測和采集分布區(qū)域內(nèi)的監(jiān)測對象或周圍環(huán)境的信息。IEEE組織和ZigBee聯(lián)盟提出的IEEEZigBee技術(shù)是一種近距
2、離、低復(fù)雜度、低功耗、低數(shù)據(jù)速率、低成本的雙向無線通信技術(shù),主要適合于自動(dòng)控制和遠(yuǎn)程控制領(lǐng)域,可以嵌入各種設(shè)備中,十分適合擔(dān)當(dāng)組織無線傳感器網(wǎng)絡(luò)的重任,有著極其重要的研究價(jià)值。本設(shè)計(jì)分析了ZigBee技術(shù)的基本理論,以及ZigBee技術(shù)的三種組網(wǎng)方式,結(jié)合國內(nèi)目前已有的傳感器技術(shù),設(shè)計(jì)了用于環(huán)境監(jiān)測的無線傳感器網(wǎng)絡(luò)系統(tǒng)方案。系統(tǒng)由傳感器節(jié)點(diǎn)、路由節(jié)點(diǎn)、協(xié)調(diào)器和上位機(jī)監(jiān)測平臺組成。傳感器采集網(wǎng)絡(luò)由分布在寫字樓中的傳感器節(jié)點(diǎn)組成,采集溫濕度、光照強(qiáng)度度等環(huán)境變量信息;每個(gè)傳感器節(jié)點(diǎn)均可作為無線網(wǎng)絡(luò)的節(jié)點(diǎn),又可單獨(dú)作為傳感器測量系統(tǒng);路由節(jié)點(diǎn)負(fù)責(zé)轉(zhuǎn)發(fā)數(shù)據(jù),增加該節(jié)點(diǎn)可擴(kuò)展無線傳輸距離;
3、協(xié)調(diào)器負(fù)責(zé)接收各個(gè)傳感器節(jié)點(diǎn)發(fā)送的數(shù)據(jù),并送到上位機(jī)顯示、分析和存儲。本設(shè)計(jì)完成了環(huán)境監(jiān)測的小型ZigBee網(wǎng)絡(luò)的搭建,實(shí)現(xiàn)了環(huán)境參數(shù)的連續(xù)檢測,傳感器測量數(shù)據(jù)準(zhǔn)確可靠。對ZigBee技術(shù)有了進(jìn)一步的認(rèn)識,對環(huán)境監(jiān)測研究也做出了相應(yīng)的貢獻(xiàn)。關(guān)鍵詞:ZigBee,Delphi,溫濕度傳感器,光照傳感器EnvironmentalMonitoringSystembasedonZigBeeABSTRACTNowadays,wirelesssensornetworksattractsmoreandmoreattentionsinthefrontedgetechnology,whichisa
