摘要
摘要：LabVIEW是實驗室虛擬儀器集成環(huán)境的簡稱，是美國國家儀器公司的產(chǎn)品。本設(shè)計介紹了虛擬儀器的功能，特點，以及應(yīng)用場合。虛擬儀器是現(xiàn)代化測量技術(shù)和計算機技術(shù)結(jié)合的產(chǎn)物，它將計算機采集測試分析引入到電子測量領(lǐng)域，用數(shù)字化和軟件技術(shù)極大提高測試的靈活性和可擴展性。LabVIEW是一種優(yōu)秀的虛擬儀器系統(tǒng)開發(fā)平臺，廣泛應(yīng)用于工控開發(fā)。本文主要介紹了虛擬儀器的概念，開發(fā)語言LabVIEW及其特點，及虛擬波形發(fā)生器，波形顯示器實現(xiàn)的一種方法。對如何利用LabVIEW圖形編程語言進行虛擬儀器開發(fā)作了闡述，還設(shè)計了溫室大棚系統(tǒng)的實現(xiàn)功能、軟件的設(shè)計思想和設(shè)計方法以及LabVIEW的編程特點。該方法可在基于PC機的測控系統(tǒng)中加以實際運用。

Warm house temperature monitoring and control system based on Virtual instrument

ABSTRACT
LabVIEW is the abbreviation of the integrated environment of fictitious instrument of the laboratory , is the products of the national instrument company of U.S.A.The VI’s function,and where it use.The Virtual instrument results from technique of electronic measurement and computer, with computers being introduced into electronic measurement filed,digital and software technology enchance the flexibility and expansibilityof measurement.LabVIEWis a excellent dummy instrument system,applied to project empolder.The concept of virtuial instrument,LabVIEWand its characteristics are introduced,as well as development of virtual instrument fore ground.One method to realize the virtual wave producer and wave diaplayer are also involved.And hou to develop Virtual instrument in graph programming Language “LabVIEW”,the function of te warm house system a designing concept and ways and te programming feature of LabVIEW is introduced.The method can be used practically in MACSYM based on PC.
