溫室限制系統(tǒng)

一、自動(dòng)限制。利用計(jì)算機(jī)技術(shù)及現(xiàn)代限制理論對(duì)溫室內(nèi)的各種環(huán)境因子，包括溫度、光照、濕度、CO2濃度和施肥等，進(jìn)展自動(dòng)限制和調(diào)整成為溫室限制的主要方式。依據(jù)溫室作物的生長習(xí)性和市場的須要，局部甚至完全擺脫自然環(huán)境的約束，使人為締造適宜作物生長最正確環(huán)境的自動(dòng)限制技術(shù)手段成為主流。此時(shí)的溫室有比擬完整的限制系統(tǒng)，有各種傳感器采集溫室環(huán)境數(shù)據(jù)，監(jiān)控系統(tǒng)實(shí)時(shí)監(jiān)測環(huán)境變更及限制執(zhí)行機(jī)構(gòu)的動(dòng)作，良好的人機(jī)界面使種植者的操作過程形象而且簡便。這種限制系統(tǒng)須要種植者輸入溫室作物生長所需環(huán)境的目標(biāo)參數(shù)，計(jì)算機(jī)依據(jù)傳感器的實(shí)際測量值與事先設(shè)定的目標(biāo)值進(jìn)展比擬，以確定溫室環(huán)境因子的限制過程，限制相應(yīng)機(jī)構(gòu)進(jìn)展加熱、降溫順通風(fēng)等動(dòng)作。計(jì)算機(jī)自動(dòng)限制的溫室限制技術(shù)實(shí)現(xiàn)了生產(chǎn)自動(dòng)化，適合規(guī)模化生產(chǎn)，勞動(dòng)生產(chǎn)率得到提高。通過變更溫室環(huán)境設(shè)定目標(biāo)值，可以自動(dòng)地進(jìn)展溫室內(nèi)環(huán)境氣候調(diào)整，但是這種限制方式對(duì)作物生長狀況的變更難以剛好作出反響，難以介入作物生長的內(nèi)在規(guī)律。目前我國絕大局部自主開發(fā)的大型現(xiàn)代化溫室及引進(jìn)的國外設(shè)備都屬于這種限制方式。

二、智能化限制。這是在溫室自動(dòng)限制技術(shù)和生產(chǎn)實(shí)踐的根底上，通過總結(jié)、收集農(nóng)業(yè)領(lǐng)域?qū)W問、技術(shù)和各種試驗(yàn)數(shù)據(jù)構(gòu)建專家系統(tǒng)，以建立植物生長的數(shù)學(xué)模型為理論依據(jù)，探究開發(fā)出的一種適合不同作物生長的溫室專家限制系統(tǒng)技術(shù)。這種智能化的限制技術(shù)將農(nóng)業(yè)專家系統(tǒng)與溫室自動(dòng)限制技術(shù)有機(jī)結(jié)合，以溫室綜合環(huán)境因子作為采集與分析對(duì)象，通過專家系統(tǒng)的詢問與決策，給出不同時(shí)期作物生長所須要的最正確環(huán)境參數(shù)，并且依據(jù)此最正確參數(shù)對(duì)實(shí)時(shí)測得的數(shù)據(jù)進(jìn)展模糊處理，自動(dòng)選擇合理、優(yōu)化的調(diào)整方案，限制執(zhí)行機(jī)構(gòu)的相應(yīng)動(dòng)作，實(shí)現(xiàn)溫室的智能化管理與生產(chǎn)。農(nóng)業(yè)專家系統(tǒng)為我們供應(yīng)了一種全新的處理困難農(nóng)業(yè)問題的思想方法和技術(shù)手段。它能夠依據(jù)溫室環(huán)境條件和作物生長狀況，應(yīng)用適當(dāng)?shù)膶W(xué)問表達(dá)和規(guī)那么化，推理決策出最適合作物生長的溫室環(huán)境。將農(nóng)業(yè)專家系統(tǒng)應(yīng)用于溫室的實(shí)時(shí)監(jiān)控與自動(dòng)調(diào)控是溫室開展的新亮點(diǎn)。這種限制方式既能表達(dá)作物生長的內(nèi)在規(guī)律，發(fā)揮農(nóng)業(yè)專家在農(nóng)業(yè)生產(chǎn)中的指導(dǎo)作用，又可充分利用計(jì)算機(jī)技術(shù)的優(yōu)勢，使系統(tǒng)的調(diào)控特殊便利和有效，實(shí)現(xiàn)溫室的完全智能化限制。因此，溫室專家限制系統(tǒng)技術(shù)
