無(wú)線傳感器網(wǎng)絡(luò)(WSN)將傳感器、計(jì)算和通信與微型設(shè)備結(jié)合起來(lái)。在現(xiàn)代農(nóng)業(yè)中,無(wú)線傳感器網(wǎng)絡(luò)(WSN)為植物的環(huán)境監(jiān)測(cè)和控制提供了一種簡(jiǎn)單而經(jīng)濟(jì)的解決方案。監(jiān)測(cè)的重要參數(shù)包括濕度和溫度。本文提出一種使用了 ZigBee技術(shù)的智能低成本無(wú)線傳感器網(wǎng)絡(luò)。隨著無(wú)線傳感器網(wǎng)絡(luò)(WSN)的發(fā)展,一種新型的不需要現(xiàn)場(chǎng)布線的溫室無(wú)線監(jiān)控系統(tǒng),己成為農(nóng)業(yè)溫室領(lǐng)域的新需求。在所提出的背景下,基于近場(chǎng)通信技術(shù)ZigBee和長(zhǎng)距離無(wú)線通信技術(shù),本文提出并設(shè)計(jì)了一種新的溫室監(jiān)測(cè)系統(tǒng)WSN模型。它具有數(shù)據(jù)傳輸可靠,維護(hù)方便,成本低的特點(diǎn)。首先,我們?cè)诿總�(gè)溫室建立了一個(gè)Zigbee無(wú)線傳感器網(wǎng)絡(luò),它有一個(gè)中心節(jié)點(diǎn)和多個(gè)采集節(jié)點(diǎn)。然后每個(gè)中心節(jié)點(diǎn)連接到GSM/GPRS模塊。然后,在這些中心節(jié)點(diǎn)上,通過(guò)GSM/GPRS模塊,在溫室管理員的移動(dòng)電話和PC機(jī)之間建立了 一個(gè)遠(yuǎn)程無(wú)線通信網(wǎng)絡(luò)。系統(tǒng)測(cè)試結(jié)果表明,以Zigbee和GPRS為核心的無(wú)線傳感器網(wǎng)絡(luò)系統(tǒng),結(jié)合溫室監(jiān)測(cè)系統(tǒng)的數(shù)據(jù)庫(kù)管理程序,是有效、可靠和可行的。這為溫室監(jiān)測(cè)系統(tǒng)的發(fā)展開(kāi)辟了一個(gè)新的階段。
