摘要：隨著現代科技的不斷發展，傳統的測試儀器已經暴露出很多的弊端。到二十世紀末，美國NI公司提出了虛擬儀器，在測控領域掀起了一場技術革命。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于傳統儀器的優勢，及其標志性語言LabVIEW的優特點；同時對虛擬儀器在遠程測控中的應用作了詳細的闡述。文章也對虛擬儀器的發展作了進一步的探討。 關鍵詞：虛擬儀器；LabVIEW；DataSocket 中圖分類號：TP311 文獻標識碼：A 文章編號：1672-4984（2006）03-0113-03 Virtual instruments and its application to remote measurement and monitoring system PENG Dai-hui¹，ZHU Shi-ping^1,2，YU Jian-qiao³ （1.College of Engineering and Technology, Southwest University, Chongqing 400716，China； 2.College of Optoelectronic Engineering, Chongqing University,Chongqing 400030，China； 3.College of Information, Southwest University, Chongqing 400716，China） 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.
