Research Of Virtual Electric Experiment Technology Based On Net

As the developing of computer, Internet and especially Virtual Instrument(VI),we can see the prosperity of virtual experiment applications. And the system of VIbased on Internet is cheaper, more effective and easier to update. These advancesmake more and more universities and research lab crowd into this subject.This paper is about how to deal with PSPICE to establish a circuit simulationblock of server, which can realize the remote simulation system of virtualexperiment. In order to expand the system, I discuss how to remote control devices ,which have GPIB I/O that can make expense-effection rate much lower byLabVIEW. Finally, in order to design circuits effective and shorten the designingtime, I make an interface of virtual experiment to display both result of PSPICEsimulation and real data collecting from GPIB devices, I also discuss how to resolvethe contrast analysis of the two data.
