Research And Design Of The Virtual Experiment Platform Based On WEB

How to conduct science and engineering's experiment teaching over the Internet is still a difficult problem to handle. With the development of modern distance education, this problem demands prompt solution.First, this paper analyzes characteristics and functions of the virtual experiment, proposes the basic structure and the architecture of constructing the virtual laboratory. Then, it focuses on the research of the key technique-experimental rules and simulation algorithm, in order to realize the correctness check, adopts production system to define experimental rules, forward reasoning strategy to conduct rule match. Furthermore, this design uses object-oriented simulation method to model the system, so an experimental platform of core part is constructed. Finally, Kirchoff law is used to verify the experiment and an initial prototype of system implementation is given.This paper uses virtual circuit laboratory experiment as the background, applies knowledge representation and reasoning technology to algorithm and rule design, and this provides a theory base and a practical case for implementation of the intelligent virtual teaching laboratory.
