Design and application of virtual instrument technology in laboratory

This paper discussed project of virtual college physics laboratory and how to realize a more open and innovative laboratory platform based on virtual technology and provided the realization principle and constitution strategy,designs hardware system and software system,as well as designs commonly-used laboratory equipment programmed by LabVIEW software.These virtual instruments are not simulation software,they are useful tools which perform basically same functions as actual instrument des.Now the virtual laboratory has been put into use in the school,the result proves that the virtual college physics laboratory has a good experiment effect.
