虚拟仪器在电气参数测试方面的应用

Application of virtual instrument on electrical parameter test

虚拟仪器是以计算机系统为基础、极具灵活性的一种新型仪器。近些年来,随着计算机技术的飞速发展,虚拟仪器也得到了很快的发展。但虚拟仪器在电气参数测试方面的应用,目前国内还比较少。通过介绍以LabVIEW为例的虚拟仪器开发平台,并以测量两同频正弦信号之间的相位差和测量单相交流电路的功率为例,说明虚拟仪器在电气参数测试方面的应用前景。

Virtual instrument is a flexible new instrument based on computer system.Recent years,virtual instrument has developed rapidly as the development of the computer technology.However,in China,it is not popular to apply the instrument in parameter test.The Labview virtual instrument development platform was introduced in the paper.Also,this paper took phase difference and power as example to show prospect of virtual instrument application in parameter test.
