Electronic Experimental Simulation Platform Based On VR Technology Design And Implementation

At present, Colleges and universities student quantity increases quickly. Traditional experiment teaching concepts drop behind. Many laboratories lack of equipments, more and more can't satisfy the student's experiment need. Schools in different places affect communication and sharing teaching resources.By using virtual reality technology, the experimental teaching system can make up for the shortage of traditional teaching. It provides a simulation environment that not restricted by space time and equipment. So the flexibility and interactive of the experiment consumedly strengthen. Students can develop an imagination and creative experiment. Using virtual teaching system, schools can flexible teaching, save money and rational use of resources. It has important meaning on modern experimental teaching reform and can improve the quality of teaching.The thesis analyzed the present condition of virtual teaching, designed a virtual experimental teaching system. First, the thesis had done the need analysis, and then expatiated on the structure of the system. Finally, it focused on the design of electronic simulation platform. The platform using virtual experimental box as the center, with all kinds of virtual devices, provided a virtual environment for electronic experiment. The platform using object-oriented programming language can easy to be maintained and expanded. In the design of the Signaling, virtual platform used a dual process united recursive algorithm and based on the source side of the trigger signal transmission. Signals can be fast and efficient transfer. Platform used the multi-thread technology. It Used independent thread to scan and control the modules run, with high real-time. The end of the thesis, it planned a virtual platform for further development.
