澆灌是彌補(bǔ)自然降水在數(shù)目上的不足與時(shí)空上的不均，保證適時(shí)適量地滿(mǎn)足作物生長(zhǎng)所需要水分的重要措施。以往的農(nóng)田澆灌，很多沒(méi)有配套完整的澆灌系統(tǒng)，注水時(shí)只能采用大水漫灌或人工灑水。不但造成水的浪費(fèi)，而且往往由于不能及時(shí)注水、過(guò)量注水或注水不足，難以控制水均勻度，對(duì)植物的正常生長(zhǎng)產(chǎn)生不利影響。我國(guó)事一個(gè)水資源短缺，水旱災(zāi)難頻繁的國(guó)家。固然水資源的總量居*六位，但是人均占有量約為世界人均水量的1/4，排在世界110位，已被聯(lián)合國(guó)列為13個(gè)貧水國(guó)家之一，同時(shí)，我國(guó)水資源的分布很不均勻，有些地區(qū)的人均占有量甚至低于世界zui貧水的國(guó)家埃及和以色列的水平。我國(guó)農(nóng)業(yè)用水量約為總用水量的80%，農(nóng)業(yè)澆灌用水的利用率普遍低下，水的利用率僅為45%，而水資源利用率高的國(guó)家已達(dá)70%～80%。建立農(nóng)田節(jié)水澆灌的自動(dòng)化系統(tǒng)，采用高效的注水方式已勢(shì)在必行。一方面可以集中治理，加強(qiáng)控制;一方面可以按時(shí)按需定量供水，嚴(yán)格控制澆灌用水量，達(dá)到節(jié)水用水目的，另一方面，可以通過(guò)自動(dòng)量測(cè)設(shè)備，實(shí)施精確計(jì)量，為按方收費(fèi)提供依據(jù)，促進(jìn)用水觀念更新，為農(nóng)業(yè)生產(chǎn)和人民生活帶來(lái)巨大的社會(huì)效益和經(jīng)濟(jì)利益。筆者利用組態(tài)軟件作為開(kāi)發(fā)平臺(tái)，開(kāi)發(fā)的農(nóng)田節(jié)水澆灌自動(dòng)控制系統(tǒng)，已在江蘇省泰興市農(nóng)業(yè)科學(xué)研究所節(jié)水澆灌示范區(qū)得到應(yīng)用。

2 節(jié)水澆灌自動(dòng)化控制系統(tǒng)的總體結(jié)構(gòu)
泰興市農(nóng)科所節(jié)水澆灌示范區(qū)的130畝土地，主要由固定噴灌區(qū)，大蓬滴灌區(qū)，露地微灌區(qū)，草坪噴灌區(qū)，低壓管道輸水澆灌區(qū)等部分組成，主要采用滴灌、噴灌、微噴灌和低壓管道輸水澆灌四種澆灌方式。整個(gè)灌區(qū)采用自動(dòng)控制系統(tǒng)，在分干管的放水孔口設(shè)置電磁閥和信號(hào)收發(fā)設(shè)備，通過(guò)電纜傳輸?shù)奖梅績(jī)?nèi)的控制中心，控制中心根據(jù)需水的孔口數(shù)目確定打開(kāi)電磁閥的個(gè)數(shù)，自動(dòng)或手動(dòng)開(kāi)機(jī)澆灌。由泵站出水口沿澆灌區(qū)設(shè)主干管，主干管沿線(xiàn)再設(shè)分干管，分干管上共設(shè)有36個(gè)給水口，由電磁閥控制后連接支管，每個(gè)給水口設(shè)置用戶(hù)給水信號(hào)開(kāi)關(guān)一只，當(dāng)用戶(hù)需要供水時(shí)，按動(dòng)信號(hào)開(kāi)關(guān)，控制中心就會(huì)有相應(yīng)的聲光報(bào)警提示，控制中心可以遠(yuǎn)程控制水泵和相應(yīng)的電磁閥，實(shí)現(xiàn)供水，當(dāng)達(dá)到預(yù)定的澆灌量水量時(shí)，可以自動(dòng)停泵或封閉電磁閥。控制系統(tǒng)主要是利用PC機(jī)遠(yuǎn)程控制一臺(tái)水泵、四臺(tái)加壓泵以及36個(gè)電磁閥來(lái)實(shí)現(xiàn)各種澆灌方式。整個(gè)控制系統(tǒng)由3個(gè)現(xiàn)場(chǎng)控制單元，每個(gè)現(xiàn)場(chǎng)控制單元由繼電器輸出模塊，數(shù)字量輸進(jìn)模塊，開(kāi)關(guān)電源，控制電源等組成，根據(jù)系統(tǒng)要求，本系統(tǒng)采用每十六個(gè)控制量由一個(gè)現(xiàn)場(chǎng)控制單元控制。節(jié)水澆灌自動(dòng)化控制系統(tǒng)的總體結(jié)構(gòu)如圖1所示。
