Research And Application Of Web-based Virtual Experiment Instrument Model

The experiment is an indispensable part of the scientific research and the higher education. Especially for the distance education, constructing the network virtual laboratory can greatly enhance the experimental efficiency and overcome the shortcomings of the traditional laboratory. And the research of network virtual experiment instrument model is crucial for the network virtual laboratory.This paper mainly researched the virtual electrics instrument model, and used the virtual reality methods to achieve the design of instrument model. Through simply compared the various virtual reality technology, this paper finally chose the virtual instrument development methods based on 3D and Virtools technology, and used the technology to research the common instrument in electronic experiment. Practice has proved that this technology can make the development of virtual instrument with better authenticity, strong interactive, simple and easy to achieve and other characteristics.This paper described the advantages of 3ds max and Virtools in detail, and realized the design of electrics common instrument by this technology. At the same time, this paper respectively taken example for the virtual multi-meter and virtual resistance box particularly described the whole process of developing virtual instrument model and achieving the instrument interaction.
