Design and implementation of an internet-based electrical engineering laboratory

•Introduce the design and implementation of the internet-based laboratory, IEE-Lab.•The IEE-Lab can provide both virtual and physical experiments.•Nearly 10,000 students from 124 continuing education centers across the nation have used the remote experiments supported by IEE-Lab.

This paper describes an internet-based electrical engineering laboratory (IEE-Lab) with virtual and physical experiments at Zhejiang University. In order to synthesize the advantages of both experiment styles, the IEE-Lab is come up with Client/Server/Application framework and combines the virtual and physical experiments. The design and workflow of IEE-Lab are introduced. The analog electronic experiment is taken as an example to show Flex plug-in design, data communication based on XML (Extensible Markup Language), experiment simulation modeled by Modelica and control terminals' design.
