基于Lab Windows/CVI的电子类课程虚拟实验室

Virtual Lab in Electronics Courses Based on Lab Windows/CVI

提出了基于LabWindows/CVI平台的电子类课程虚拟实验室的研究,设计了虚拟仿真信号发生器,虚拟低通滤波器,实验效果良好,并对虚拟实验室的网络化构建作了介绍。利用Internet进行虚拟实验室的网络发布,实现了资源共享,避免了仪器重复添置和资源浪费,使客户的远程实时操作不再受时间、地点限制,提高了客户的利用效率。虚拟实验室的建立弥补了传统实验室的不足,使实验的设计更加灵活,为接受远程实验教学的学生提供了一种不受时间,地点和实验设备限制的实验环境。它作为一种新型的科研与教学资源越来越受到人们的关注。

Virtual lab in electronics courses based on LabWindows/CVI is proposed in this paper. We design virtual signal generator, and virtual Low Pass Filter, which is attended with good results, introduced the network compose to build the virtual Lab; publish the Web of Virtual lab by internet, achieve resource sharing and avoid duplication of equipment purchase and waste of resources. Remote real-time operation of customers will no longer subject to time and place and improve the efficiency. The establishment of virtual laboratory covers the shortage of traditional lab and makes the design of experimentation more flexible. It provides students with a free time, place and unrestricted experiment environment. As a new research and teaching resources, it is more and more paid attention to.
