本(ben)文設計了一種(zhong)基于LabVIEW2010和STC89C52單片機的(de)溫(wen)(wen)室(shi)(shi)(shi)環境監測系統(tong)，并利用(yong)數字式溫(wen)(wen)濕(shi)度(du)(du)傳感器AM2315對(dui)溫(wen)(wen)室(shi)(shi)(shi)內外的(de)溫(wen)(wen)濕(shi)度(du)(du)進行多點實時(shi)采集和處理，并能根據溫(wen)(wen)室(shi)(shi)(shi)內外的(de)溫(wen)(wen)濕(shi)度(du)(du)的(de)差異(yi)自動判斷(duan)卷簾高(gao)度(du)(du)和通(tong)風口的(de)大小，實現了與控(kong)(kong)制(zhi)(zhi)。該系統(tong)硬件結構簡單、成本和功耗(hao)較低、使(shi)用(yong)(yong)方便靈活、維護(hu)和布線簡單、軟件操(cao)作(zuo)(zuo)簡單、工(gong)作(zuo)(zuo)穩定可靠。將溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)環(huan)境監(jian)測應(ying)用(yong)(yong)到(dao)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)大棚的(de)(de)(de)(de)(de)(de)生產管(guan)理(li)(li)中代替(ti)人(ren)工(gong)方式(shi)(shi)，可以節省(sheng)大量(liang)的(de)(de)(de)(de)(de)(de)人(ren)力物(wu)力，有(you)(you)效解(jie)決數據采(cai)集耗(hao)時耗(hao)力、時效性(xing)差(cha)、易受干擾(rao)、準確性(xing)低等(deng)問(wen)題，從而提高溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)自動化水(shui)平(ping)和管(guan)理(li)(li)水(shui)平(ping)，將溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)內的(de)(de)(de)(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)和濕度(du)控(kong)(kong)制(zhi)(zhi)在適合植物(wu)生長的(de)(de)(de)(de)(de)(de)范(fan)圍內，可充分發揮溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)農業的(de)(de)(de)(de)(de)(de)高效性(xing)，提高農作(zuo)(zuo)物(wu)的(de)(de)(de)(de)(de)(de)產量(liang)和質量(liang)。溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)環(huan)境控(kong)(kong)制(zhi)(zhi)雖然已(yi)經(jing)研究(jiu)多年，在控(kong)(kong)制(zhi)(zhi)算(suan)法等(deng)方面(mian)也取(qu)得了不少成果(guo)，但能(neng)有(you)(you)效應(ying)用(yong)(yong)于實際溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)控(kong)(kong)制(zhi)(zhi)的(de)(de)(de)(de)(de)(de)成果(guo)卻不多。究(jiu)其原因，最(zui)主要(yao)(yao)的(de)(de)(de)(de)(de)(de)是，當(dang)前(qian)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)環(huan)境監(jian)測都面(mian)臨一個最(zui)基本的(de)(de)(de)(de)(de)(de)問(wen)題，即(ji)缺(que)乏溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)環(huan)境控(kong)(kong)制(zhi)(zhi)所(suo)(suo)需要(yao)(yao)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)系統(tong)精(jing)確模(mo)型。因此(ci)，建立面(mian)向(xiang)控(kong)(kong)制(zhi)(zhi)需求(qiu)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)系統(tong)精(jing)確模(mo)型，是實現(xian)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)生產過程最(zui)優控(kong)(kong)制(zhi)(zhi)的(de)(de)(de)(de)(de)(de)前(qian)提和基礎。要(yao)(yao)真實反映控(kong)(kong)制(zhi)(zhi)執(zhi)行機構動作(zuo)(zuo)與系統(tong)狀態(tai)變化之間的(de)(de)(de)(de)(de)(de)動態(tai)關系，模(mo)型中必須要(yao)(yao)包含執(zhi)行機構的(de)(de)(de)(de)(de)(de)這(zhe)種動態(tai)性(xing)能(neng)，例(li)如(ru)不同(tong)(tong)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)環(huan)境監(jian)測的(de)(de)(de)(de)(de)(de)控(kong)(kong)制(zhi)(zhi)執(zhi)行機構（例(li)如(ru)管(guan)道熱水(shui)式(shi)(shi)加(jia)熱或(huo)熱風機式(shi)(shi)空(kong)氣(qi)加(jia)熱）會導致(zhi)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)系統(tong)升溫(wen)(wen)(wen)(wen)(wen)速(su)度(du)的(de)(de)(de)(de)(de)(de)不同(tong)(tong)，亦即(ji)其動態(tai)模(mo)型有(you)(you)所(suo)(suo)不同(tong)(tong)—這(zhe)也是面(mian)向(xiang)控(kong)(kong)制(zhi)(zhi)的(de)(de)(de)(de)(de)(de)溫(wen)(wen)(wen)(wen)(wen)室(shi)(shi)(shi)(shi)系統(tong)模(mo)型與單純的(de)(de)(de)(de)(de)(de)作(zuo)(zuo)物(wu)生長模(mo)型或(huo)小氣(qi)候(hou)環(huan)境模(mo)型的(de)(de)(de)(de)(de)(de)根本不同(tong)(tong)之處。
