Internet-based electrical engineering lab integrates real and virtual experiments

This paper describes the application of an internet-based electrical engineering lab (iEELab) integrated with both real and virtual experiments. The real experiments are based on authentic physical devices, while the virtual ones based on simulation models using Modelica for unified modeling. The unique lab offers combination of real and virtual experiments, which has built a bridge between theoretical lessons and laboratory classes. The productive lab provides distance education students with six courses in electrical engineering and automation, including circuit theory, analog electronic technique, digital electronic technique, microelectronics, DSP and MCU. The instructive lab enables users to design and check their own circuit diagram. Also users can get real physical experiment results and virtual simulation results simultaneously, so they can make a clear parallel between the two results from different backstage calculation module. The whole system has good expansibility and new experiment modules can be flexibly added.
