The Application Of Virtual Technology In The Electrical And Electronic Experiments

This paper discribes a project which improves the old closed teaching mode and make some innovations to Lab-teaching. With the gradually opening of electronics laboratory , as well as the rapid increasement of user information and experimental data, a mass of data makes old management mode is unable to meet the need of experimental information management. Therefore, it is necessary for us to build an open laboratory, students can choose the optional experiments of their own according to their interests. By repeated circuit testing and fault inquiring, students can find a best way for experiments and produce good results. The development of applied computer science, instrumental technology and network technology ingect great vitality to the Electronic Laboratory. When web technique expands to the region of instrument, information system and measurement system can be linked with no seam, so current electronic laboratory can be developed to be a kind of virtual web laboratory through Internet or Intranet, which makes the limited resources can be shared furthest.The research and development of Virtual instruments are decribed in this paper, which bring new idears to the construction of EDA laboratory. The author have tried to developed a few kind of virtual instruments which usually have been used in electric electronics experiments, and build a small-scale experimental platform. Combining the features of experimental teaching of Electrical and Electronic, we do some comparisons between traditional instruments and virtual instruments, and make analyses of the existing shortcomings of current virtual machines. In addition, a experimental management system has also been introduced in the paper, which involved me more than half year to do research about it. The experimental management system provide a foundation for the Open Laboratory. In the end, the author focuses on the structure and functions of virtual instrument, as well as a few methods of the implements of the whole VI platform. The opening virtual network laboratory is now in futher improvement. It aims to provide good service to the students and teachers and make them get access to the laboratory whenever and wherever as long as they are on Internet or Intranet.The project introduced in this paper is involving virtual instruments designing and development and its application of experimental management system. The engineering problems of designing to be solved in this project are difficult and includes great massive work. The full completion of the project brings some benefitial designing experience for experimental teaching innovation. Also, it has great value in application and expanding in other universities.
