Study Of Real-Time Remote Laboratory Teaching System Based On Real Experiment Board

With the development of society and university enrollment, most schools are facing the same problem that the number of student is growing but experiment equipment is limited; student has less time doing experiments due to the number of participants, limited equipment. The Laboratories are always opened for only a short time, there is a relatively long time that laboratory equipment is vacant, resulting in a waste of resources. Under a national environment that encourages innovation, students’innovation ability is important, but the above-mentioned problems caused students has fewer hours to practice, which greatly affected the ability to improve students’ innovation ability. At present time, the restrictions limit the experimental resources has become an important bottleneck in the development of experimental teaching, especially in the field of network continuing education of experimental.In response to these problems exist in electronic circuit experiment teaching, this paper proposes a real-time remote experiment teaching system based on real experiment board, on which student can see the real phenomenon by the video, and real-time signal waveform by using the virtual instrument. The experiments’ phenomena are real, we present these real-time phenomenon to users by certain techniques. The system is designed for the students of electronic engineering related majors, which can provide analog circuit experiment and digital logic experiment. Now the system supports6analog circuit experiment and15digital logic experiment.The system has3roles, student, teacher and administrator. Students can look up experiment list and finish experiment and upload experiment report through the system. The teacher can view experiment list of classes they are charged in, and check the completion status of the experiment, they also can correct the students’ experiment report and grade them. Administrators can manage all the information of the system, including student information, teacher information, experiment information and experiment information and so on. The experimental platform’s maintenance can also be done by the administrator through the system.This paper discusses the subsystems and modules of the system, and demonstrates implementation of some key modules and technique. At the same time, the system put forward some specific solutions for the potential problems exist in the future.
