摘要：隨著現(xiàn)代科技的不斷發(fā)展，傳統(tǒng)的測(cè)試儀器已經(jīng)暴露出很多的弊端。到二十世紀(jì)末，美國(guó)NI公司提出了虛擬儀器，在測(cè)控領(lǐng)域掀起了一場(chǎng)技術(shù)革命。本文概述了虛擬儀器的概念、各組成部分及其虛擬儀器相對(duì)于傳統(tǒng)儀器的優(yōu)勢(shì)，及其標(biāo)志性語(yǔ)言LabVIEW的優(yōu)特點(diǎn)；同時(shí)對(duì)虛擬儀器在遠(yuǎn)程測(cè)控中的應(yīng)用作了詳細(xì)的闡述。文章也對(duì)虛擬儀器的發(fā)展作了進(jìn)一步的探討。

Abstract：With the development of the modern science and technology, many defects of the traditional testing instruments have been exposed. By the end of the 20th century, the concepts of the Virtual Instruments have been come up with by the NI Corporation in the United States, which resulted in the
revolution in measurement and monitoring technology. The definitions of the Virtual Instruments, their components as well as superiorities to traditional testing instruments were represented in this paper.And also some characteristics of the LabVIEW, the representative language of Virtual Instruments, were introduced in this paper. The application to remote measurement and monitoring system was also proposed. Finally, conclusion and recommendations for further investigation were given in this paper.
Key words：Virtual instruments;LabVIEW；DataSocket
