The Research And Accomplishment Of Virtual Laboratory On LabVIEW

Experiment teaching has been playing an increasingly important role in high education. It's a key measure to improve the students' ability. Virtual Laboratory appears with the development of computer technique and Virtual Instrument technique. As an essential and beneficial supplement to the traditional experiment, virtual experiments not only save a lot of education funds, but also extend the experiments in time and space effectively. It has the vast applied foreground in the education and research realm. Virtual Laboratory is a new development direction of the experiment teaching as well as an active research topic recently. Therefore, the development of the virtual laboratory of network is very necessary.This thesis discusses on the construction of virtual laboratory from theoretical research, technological route and application development. It has, emphatically, discussed relevant theories, modeling methods and key technologies of virtual laboratory, According to theory framework, modeling methods and technological scheme mentioned above, an intelligent "the Virtual Laboratory for Power Electric Experiment", is constructed.The virtual laboratory is integrated with experiment teaching, experiment operation and experiment report. In the virtual laboratory, the instruments are developed as components, which improve the developing efficiency and the reusing of software. The Matlab are used for simulating and computing in the server, which enhances the simulation capability. Compared with other simulation software of electronic circuits, this system achieves excellent performance in the capability of extension and interaction with sense of reality. In the virtual laboratory, users can "connect" electronic circuits freely using various kinds of "virtual components and apparatus" in the realistic multimedia "virtual scene", and can also receive the simulation result in real time via the "measure" of the corresponding "virtual instruments", which makes users operate it with great interest just like doing real experiments and gains good effect in experimental teaching.
