無線傳感器網(wǎng)絡在農(nóng)業(yè)溫室測控系統(tǒng)中的應用
發(fā)布時間：2025-01-15 10:49
無線傳感器網(wǎng)絡(WSN)將傳感器、計算和通信與微型設備結(jié)合起來。在現(xiàn)代農(nóng)業(yè)中,無線傳感器網(wǎng)絡(WSN)為植物的環(huán)境監(jiān)測和控制提供了一種簡單而經(jīng)濟的解決方案。監(jiān)測的重要參數(shù)包括濕度和溫度。本文提出一種使用了 ZigBee技術(shù)的智能低成本無線傳感器網(wǎng)絡。隨著無線傳感器網(wǎng)絡(WSN)的發(fā)展,一種新型的不需要現(xiàn)場布線的溫室無線監(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,基于近場通信技術(shù)ZigBee和長距離無線通信技術(shù),本文提出并設計了一種新的溫室監(jiān)測系統(tǒng)WSN模型。它具有數(shù)據(jù)傳輸可靠,維護方便,成本低的特點。首先,我們在每個溫室建立了一個Zigbee無線傳感器網(wǎng)絡,它有一個中心節(jié)點和多個采集節(jié)點。然后每個中心節(jié)點連接到GSM/GPRS模塊。然后,在這些中心節(jié)點上,通過GSM/GPRS模塊,在溫室管理員的移動電話和PC機之間建立了 一個遠程無線通信網(wǎng)絡。系統(tǒng)測試結(jié)果表明,以Zigbee和GPRS為核心的無線傳感器網(wǎng)絡系統(tǒng),結(jié)合溫室監(jiān)測系統(tǒng)的數(shù)據(jù)庫管理程序,是有效、可靠和可行的。這為溫室監(jiān)測系統(tǒng)的發(fā)展開辟了一個新的階段。
