Aiming at the condition that laboratory instrument resource can not meet the demands of experimental teaching,management and upgrading because of shortage, decentralization, obsolescence and aging, therefore, a design proposal of network experiment system based on Lab VIEW is presented. The data transmission of tree modules which are virtual instruments, simulation and real time measure is achieved with application of Data at Socket technology and Remote Panels technology. Practical application shows that this system can reduce attrition rate of machines and improve the utilization efficiency of instruments and it has some other advantages including short development period, low cost, good compatibility, good extensibility and easy update for equipments. The network construction based on virtual instrument technology has broad prospects in industry and scientific experiment.
