摘要
摘要:LabVIEW是实验室虚拟仪器集成环境的简称,是美国国家仪器公司的产品。本设计介绍了虚拟仪器的功能,特点,以及应用场合。虚拟仪器是现代化测量技术和计算机技术结合的产物,它将计算机采集测试分析引入到电子测量领域,用数字化和软件技术极大提高测试的灵活性和可扩展性。LabVIEW是一种优秀的虚拟仪器系统开发平台,广泛应用于工控开发。本文主要介绍了虚拟仪器的概念,开发语言LabVIEW及其特点,及虚拟波形发生器,波形显示器实现的一种方法。对如何利用LabVIEW图形编程语言进行虚拟仪器开发作了阐述,还设计了温室大棚系统的实现功能、软件的设计思想和设计方法以及LabVIEW的编程特点。该方法可在基于PC机的测控系统中加以实际运用。

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.
