ChangchunUniversityOfScienceAndTechnology英文文獻翻譯學(xué)生姓名朱澤龍專業(yè)電氣工程及其自動化學(xué)號1134155分院電子工程分院2015年7月基于主從散布式新的溫室環(huán)境參數(shù)監(jiān)測和控制系統(tǒng)按如實際在農(nóng)村地域的溫室環(huán)境參數(shù)的監(jiān)測和控制，主從散布式測量和控制系統(tǒng)的設(shè)計需要，以其中一臺運算機作為主機，該系統(tǒng)由PC、土壤水分測量和控制模塊，溫度、濕度、CO2監(jiān)測和控制模塊組成。在該系統(tǒng)中，電腦有大量的數(shù)據(jù)存儲的功能，它很容易利用模糊控制專家，配置組態(tài)軟件組態(tài)王用來開發(fā)PC軟件，具有開發(fā)周期縮短和友好的人機交互的優(yōu)勢。每一個監(jiān)測和控制模塊包括STC12系列的微控制器、傳感器、繼電器等等。若是系統(tǒng)實現(xiàn)控制溫室在分區(qū)和塊，需要選擇不同的模塊。一，簡介現(xiàn)代化農(nóng)業(yè)的室內(nèi)，環(huán)境參數(shù)的自動測量和控制是實現(xiàn)作物產(chǎn)量和品質(zhì)的關(guān)鍵。在最近幾年來，設(shè)施農(nóng)業(yè)在我國蓬勃進展，與之匹配的，具有監(jiān)測和控制儀器的溫室也有取得了必然的進展。近10年的不懈盡力，咱們的研究團隊在農(nóng)業(yè)環(huán)境參數(shù)的測量和控制系統(tǒng)上，設(shè)計了一個智能測量和控制系統(tǒng)相散布結(jié)合的溫室，能夠在廣大農(nóng)村地域適用。那個系統(tǒng)主如果控制溫度、濕度、二氧化碳濃度、土壤水分和照明溫室。單片機，作為數(shù)據(jù)存儲空間較小，單一的顯示接口，有限的信息容量，但其有較高的性價比，因此它作為前端的數(shù)據(jù)收集和控制單元為PC利用，它有大量的數(shù)據(jù)存儲，豐碩的軟件，方便的人機交互等長處。若是咱們利用過時的和低價的電腦，以PC機作為上位機，以不同的功能控制模塊和多個微型運算機作為降低機械，然后組成一個基于微機的主從散布式和智能化控制系統(tǒng)，既更好的監(jiān)視和控制、顯示和數(shù)據(jù)搜集或管理的實現(xiàn),而且費用低，系統(tǒng)會按如實際的需要選擇。二，系統(tǒng)結(jié)構(gòu)及原理最顯著的特點是分派和智能控制系統(tǒng)溫室相結(jié)合，這將作為一個整體，模塊組合結(jié)構(gòu)簡單，方便的人機交互與數(shù)據(jù)收集，控制和管理，并采用模糊控制技術(shù)的智能專家，能夠組成適應(yīng)多種作物管理控制的溫室。其大體結(jié)構(gòu)系統(tǒng)是圖1所示。散布式系統(tǒng)的結(jié)構(gòu)是由兩層組成：上部和下部。由最佳價錢PC被取為主機，使其能夠智能系統(tǒng)管理和專家模糊運算，并提供一個友好的人機界面，并實現(xiàn)統(tǒng)一的監(jiān)控和管理的溫室;下部是由一系列不同功能的模塊，而且在每一個模塊中，一個單一的芯片作為下位機采用AT89C52,RS485則用于與所有AT89C52PC進行通信，然后實現(xiàn)搜集，處置和控制的溫室參數(shù)。每一個功能模塊是完全地電氣隔離，任何失敗的結(jié)節(jié)不會對其他模塊產(chǎn)生任何影響。系統(tǒng)通過別離搜集環(huán)境信息的方式，每一個監(jiān)控和控制模塊，并通過RS485接口將其發(fā)送到主機PC。而且由PC配置控制系統(tǒng)，額定參數(shù)的設(shè)定值進行比較，然后按照專家智能模糊控制系統(tǒng)測量作物在不同生長階段的各類環(huán)境的溫度，濕度，CO2濃度，土壤含水量進行相應(yīng)的操作指令或報警，模糊控制指令。在秦皇島農(nóng)村大棚。通常在一個溫室的近東和西區(qū)的1/4區(qū)域，距離地面為米的中間北部的一半（近濕簾）和南部的一半（風(fēng)扇周圍的），設(shè)置一個模塊檢測空氣溫度、濕度、二氧化碳濃度和土壤水分含量，按如實際情形，將土壤含水量模塊添加在溫室的中間;在高度為米的主入口，設(shè)置一個水箱，其中的電磁閥滴水管應(yīng)按照土壤水分含量的需要設(shè)置和控制，而且將電腦放置在主入口的溫室內(nèi)。三，硬件設(shè)計和通信系統(tǒng)散布式系統(tǒng)中的數(shù)據(jù)收集和控制：由于微型控制單元局限于在數(shù)據(jù)存儲和計算復(fù)雜，所以電腦所的利用和主從模塊系統(tǒng)所采用的，這是一個系統(tǒng)，以PC機作為主機，以單片機作為子機。在這種散布式系統(tǒng)中，通信是關(guān)鍵。通常，PC機的串行端口是標(biāo)準(zhǔn)的RS232,傳輸距離較短?？墒窃谵r(nóng)業(yè)控制系統(tǒng)，其通信距離的數(shù)十公尺或幾千米，所以RS232/RS485轉(zhuǎn)換器通過PC機與單片機之間的通信來實現(xiàn)。減少投資，既考慮用戶方便和友好的人機交互，低價電腦的上面和下面采用PIV486,并考慮組態(tài)軟件的操作，內(nèi)存是必需是64M以上，硬盤是10GB以上。B.控制模塊的溫度和濕度，照明度和CO2濃度2每一個控制單元包括供給鏈管理（SCM），傳感器，信號處置電路，RS485接口和輸出環(huán)節(jié)。此模塊的溫度和濕度，二氧化碳濃度的硬件結(jié)構(gòu)示于圖2?；贜DIR技術(shù)測量CO2濃度的傳感器，測量范圍是0s2X103摩爾。通過傳感器，控制系統(tǒng)，利用軟件數(shù)字濾波、線性插值和溫度補償，取得二氧化碳的濃度，依附數(shù)字UART協(xié)議，然后直接輸入單片機。新的智能傳感器SHT11基于選擇CMOSens技術(shù)測量溫度和濕度。在SHT11,溫度和濕度傳感器、信號放大，A/D,I2C總線全數(shù)集成在一個芯片上，它有滿刻度校準(zhǔn)，第二行數(shù)字輸出而且濕度測量范圍為0s100%RH,溫度測量范圍為-40℃~+123。8℃,濕度測量精度為土3。0%口氏溫度測量精度為土0。4℃,響應(yīng)＜4的時刻。JY1-TBQ-6的照度傳感器的硅光伏檢測是利用光測量。它的測量范圍為0s200000勒克斯;光譜范圍為400s700（nm）的可見光;測量誤差是小于2%,輸出為4?20mA或0s20mV,輸出信號能夠直接傳送到A/D的單片機放大后，大小為0s4V。模塊同意指令形成上層，輸出通過輸出電路。輸出電路包括光學(xué)隔離、信號驅(qū)動，輸出繼電器。C.土壤水分的測量和控制模塊水是一種極性介質(zhì)，土壤的介電常數(shù)包括水，主如果由水決定，當(dāng)水含量是不同的，波阻抗不同。在那個系統(tǒng)中，土壤水分測量是通過駐波無線電的方式?；诠こ屉姶艌隼碚摚袚p介質(zhì)，如下的電磁波阻抗：Z0=JH/￡(1+j入/(3￡))其中，口是介質(zhì)滲透性，土壤和口是口心口0是真空磁導(dǎo)率；￡是介質(zhì)的介電常數(shù)，入是介質(zhì)電導(dǎo)率;3是電磁波頻。在超級低的音頻(<2000hz)，損耗角正切的干土介質(zhì)是人/3￡'0。07,若是你選擇的信號源的頻率高于20兆赫茲。然后，￡心￡8,虛部的土壤波阻抗輕忽，只有真正的一部份，這相當(dāng)于一個純電阻。土壤水分傳感器由100MHz信號源，同軸傳輸線和插件不銹鋼探針組成。電磁波信號沿著線傳輸?shù)教筋^。由于探針阻抗和線路阻抗不同，入射波和反射波的疊加形成駐波。以同軸傳輸線作為無損耗均勻線，波阻抗為Z0,ZL是負(fù)載阻抗。然后，在探針的電壓波的反射系數(shù)是：「二(Zl-Z0)%+4)選擇傳輸線的長度為『人/4時，該行的兩頭的最大和最小Umax和Umin時，然后駐波無線電行中，能夠表示為：S=Umax/Umin=(1-'r')/(1+'r')依照這種方式，土壤水分無線電能夠通過測量傳輸線的駐波率取得。如圖3所示。土壤水分模塊包括傳感器和控制器，傳感器服從控制器，控制器能夠被省略，而不需要澆灌溫室。在那個系統(tǒng)中，分區(qū)節(jié)點為了簡化控制、澆灌技術(shù)，采用控制土壤水分技術(shù)。在必然的程度上，那個參數(shù)的上部和下部地面可采用該技術(shù)解耦。四，控制系統(tǒng)編程該PC軟甲的開發(fā)由北京組態(tài)王6。51控制。那個配置軟件具有靠得住性高，開發(fā)周期短，完美的圖形界面生成能力，和友好的人機交互，能夠依照創(chuàng)建動態(tài)圖像和圖表能夠直觀地顯示設(shè)備的布局場景中的參數(shù)，控制狀態(tài)的轉(zhuǎn)變，并能發(fā)出報警信號，當(dāng)超過額定值，能夠?qū)崿F(xiàn)模糊控制的溫室參數(shù)利用的特定數(shù)據(jù)庫中存儲的歷史環(huán)境參數(shù)曲線并采用農(nóng)業(yè)專家系統(tǒng)。軟件配置管理是由C51單片機實現(xiàn)實時解答搜集、處置、上傳的參數(shù)和同意模糊控制指令從主機運算機和完整的局部控制的裝置。A,控制模塊的程序設(shè)計子機的軟件的土壤濕度模塊的主要功能包括數(shù)據(jù)收集和處置子程序，中斷處置和通信等，通過并行數(shù)據(jù)接口取得駐波電壓的數(shù)值而且由函數(shù)計算取得土壤含水量。軟件的子機主要與下位機完成對土壤水分檢測和控制的數(shù)據(jù)通信，測量數(shù)據(jù)和電流控制上傳狀態(tài)到主機電腦，同意模糊控制指令從主機運算機輸出執(zhí)行指令。子機的溫度、濕度和二氧化碳的硬件模塊主如果完成讀取I2C濃度的二氧化碳濃度、溫度和濕度，測量數(shù)據(jù)和電流控制上傳狀態(tài)到主機電腦，同意模糊控制指令從主機輸出執(zhí)行指令。那個主程序和中斷子程序的溫度和濕度的模塊的結(jié)構(gòu)如圖4所示。串行中斷模式3采用所有從機與主機通信，傳輸數(shù)字化收集和接收指令。和模糊控制系統(tǒng)的程序設(shè)計1)組態(tài)王的通信設(shè)置：為了確保通信的正確性，上下必需遵循相同的通信協(xié)議，通信參數(shù)。通常在通信，采用主從方式在風(fēng)格和應(yīng)答器是采用的進程。換言之，第一主發(fā)命令給子機，然后等子機接到指令后給出答案，通信成立。在組態(tài)王，一個預(yù)定的輪詢方式被用來做閱讀和寫作的低機械電腦之間。在項目閱讀器中，第一，單擊設(shè)備一COM1;在設(shè)備配置向?qū)е?，選擇“智能模塊”一單片機fSCM的HEX一串行端口，然后服務(wù)主機的通信參數(shù)。2)組態(tài)王和數(shù)據(jù)庫的連接數(shù)據(jù)庫的核心是軟件，不僅包括了概念的變量，實時參數(shù)和歷史參數(shù)，可是還需要在參數(shù)報警、模糊計算、報告和顯示。ACCESS2003的桌面數(shù)據(jù)庫是用來記錄數(shù)據(jù)庫的系統(tǒng)，并通過利用SQL,由組態(tài)王通過開放式數(shù)據(jù)庫連接性實現(xiàn)的。那個進程是：在組態(tài)王來創(chuàng)建數(shù)據(jù)變量創(chuàng)建一個身體的記錄成立數(shù)據(jù)源的ODBC來創(chuàng)建查詢屏幕和使屏幕連接。到與微軟Access2003,功能SQLSelect,SQLConnect(),SQLLastSQLFist,SQLNext(),QSLPrew(),SQLInsrt,SQLPrew()等等，實現(xiàn)的命令語言，然后實時存儲和查詢的數(shù)據(jù)完成。3)PC軟件設(shè)計：溫室控制系統(tǒng)，數(shù)據(jù)存儲容量的PC是無窮的，因此，若是現(xiàn)有的成熟的軟件模塊到系統(tǒng)，它都能夠輕松提高系統(tǒng)的靠得住性。軟件，軟件由控制模塊和管理模塊。4)軟件系統(tǒng)的主控制界面，輔助數(shù)據(jù)庫等。典型的監(jiān)測和控制的PC的主界面如圖5所示。五，結(jié)論按照經(jīng)濟經(jīng)受能力，農(nóng)人在秦皇島，與現(xiàn)有技術(shù)的溫室環(huán)境參數(shù)的監(jiān)測和控制，主從散布式溫室環(huán)境自動控制系統(tǒng)在其中一臺運算機作為主機系統(tǒng)，研制了具有以下特點：1）憑借其大容量的數(shù)據(jù)存儲，PC,模糊控制專家系統(tǒng)的數(shù)據(jù)存儲，修改和系統(tǒng)升級是很容易的。2）利用組態(tài)王軟件開發(fā)的PC，提高了系統(tǒng)的靠得住性，縮短開發(fā)周期，并取得一個友好的人機界面。系統(tǒng)中利用的一個散布式，模塊化結(jié)構(gòu)，它使系統(tǒng)保護加倍容易，而且適應(yīng)生產(chǎn)需要。的從屬的監(jiān)測和控制模塊連接到主機上，然后按照需要通過RS485總線控制溫室中分區(qū)或塊能夠?qū)崿F(xiàn)的。致謝這項工作是支持的農(nóng)業(yè)科技功效轉(zhuǎn)化基金項目。NewEnvironmentParametersMonitoringAndControl
