摘　　要：针对高等院校的实验仪器资源相对短缺、分散和陈旧老化而无法满足实验教学需求、管理和更新升级的状况,提出了一套基于LabVIEW的网络虚拟实验系统的构建方案。该方案采用DataSocket技术和Remote Panels技术实现了虚拟仪器、模拟仿真和实时测量三大模块的数据传输。实际运行结果表明,该系统降低了实物损耗率,能够大大提高仪器的使用效率,且开发周期短、成本低,同时又具有很强的兼容性和扩展性,易于升级换代和维护,基于虚拟仪器技术的网络建设在工业以及科研实验中具有广阔的应用前景。Aimed 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 LabVIEW is presented.The data transmission of tree modules is achieved with application of DataSocket technology and Remote Panels technology,which are virtual instruments,simulation and real time measure.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.
