1、中國(guó)科學(xué)技術(shù)大學(xué)碩士學(xué)位論文基于無(wú)線傳感器網(wǎng)絡(luò)的數(shù)據(jù)獲取系統(tǒng)研究姓名:范奎申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):模式識(shí)別與智能系統(tǒng)指導(dǎo)教師:宋良圖20100501摘要無(wú)線傳感器網(wǎng)絡(luò)是由大量具有感知能力、計(jì)算能力和通信能力的微小傳感器節(jié)點(diǎn)構(gòu)成的自組織、分布式網(wǎng)絡(luò)系統(tǒng)。通過(guò)GPRS終端將無(wú)線傳感器網(wǎng)絡(luò)獲取的數(shù)據(jù)傳輸?shù)竭h(yuǎn)程的上位機(jī)上,從而實(shí)現(xiàn)監(jiān)測(cè)現(xiàn)場(chǎng)數(shù)據(jù)的遠(yuǎn)程獲取。在安徽省農(nóng)業(yè)科技成果轉(zhuǎn)化資金項(xiàng)目一“農(nóng)業(yè)實(shí)時(shí)信息獲耿與數(shù)字化管理系統(tǒng)中試”(2007GB24910458)的支持下,本文圍繞基于無(wú)線傳感器網(wǎng)絡(luò)的遠(yuǎn)程數(shù)據(jù)獲取系統(tǒng)的設(shè)計(jì)進(jìn)行研究。本文主要做了以下幾
2、點(diǎn)工作:1.對(duì)基于無(wú)線傳感器網(wǎng)絡(luò)的數(shù)據(jù)獲取系統(tǒng)進(jìn)行硬件設(shè)計(jì),詳細(xì)設(shè)計(jì)了系統(tǒng)的供電模塊,研究了電源的整流、濾波、以及抗干擾技術(shù):設(shè)計(jì)了統(tǒng)一傳感器接口模塊,例如:標(biāo)準(zhǔn)電流轉(zhuǎn)電壓模塊,分析了電壓轉(zhuǎn)換精度等問(wèn)題。2.簡(jiǎn)單介紹了Zigbee協(xié)議棧,然后在此協(xié)議棧的基礎(chǔ)上針對(duì)項(xiàng)目實(shí)際需要進(jìn)行了的二次丌發(fā),滿足項(xiàng)目需求。在本系統(tǒng)中,利用簇樹(shù)型網(wǎng)絡(luò)拓?fù)溆行У臄U(kuò)大了無(wú)線網(wǎng)絡(luò)的覆蓋面積,最終試用所丌發(fā)的二次系統(tǒng)軟件,應(yīng)用良好。3.設(shè)計(jì)了基于無(wú)線傳感器網(wǎng)絡(luò)的數(shù)據(jù)獲取平臺(tái)。通過(guò)該軟件平臺(tái)實(shí)現(xiàn)了對(duì)部署在監(jiān)測(cè)現(xiàn)場(chǎng)的無(wú)線傳感器網(wǎng)絡(luò)運(yùn)行情況的遠(yuǎn)程監(jiān)測(cè),命令發(fā)送,數(shù)掘接
3、收、顯示和記錄,并提供了報(bào)警功能,將不在設(shè)定門(mén)限值范圍內(nèi)的傳感器數(shù)據(jù)作出記錄并給出相應(yīng)的報(bào)警提示,方便管理者及時(shí)作出相應(yīng)的決策。4.搭建出遠(yuǎn)程數(shù)據(jù)獲取平臺(tái),并進(jìn)行實(shí)驗(yàn),效果理想。關(guān)鍵詞:無(wú)線傳感器網(wǎng)絡(luò)ZigBee低功率電源設(shè)計(jì)AbstractTheWSNisaself-organizeddistributednetworksystemwhichiscomposedofamassoftinysensorsnodesthathasthesensationability.Thewirelesssensornetworknodewhichdep
