Research On Key Technology Of High Voltage Experiment Teaching Project Simulation System Based On VR

High voltage experiment teaching is an important part of electrical engineering courses,but the traditional teaching form is single,the content is boring,and the interaction is not strong,resulting in students can not effectively grasp the experimental principles and methods,and it is easy to misoperate in practice,causing equipment damage and even causing safety accidents.In addition,due to the lack of experimental equipment,students can not get enough experimental time.In view of the lack of related research on high voltage experiment teaching simulation system of similar electrical engineering specialty in China,aiming at the above shortcomings,this paper designs and develops a high voltage experiment teaching project simulation system based on high voltage experimental equipment of electrical engineering specialty.The main research contents and innovative work are as follows:(1)Based on the analysis of the problems existing in high voltage experiment teaching,combined with the research status of virtual reality technology in electrical field at home and abroad,the design scheme of high voltage experiment teaching project simulation system is given,and its key technology is studied.(2)Through the combination of traditional 3D modeling technology and automatic3 D modeling technology,the 3D models of operating platform,insulation megger,protective ball gap and other equipment are constructed,which optimizes the development process and improves the development efficiency.(3)The optimized half fold algorithm is used to optimize the data volume of 3D model,which improves the optimization efficiency.The technical details of level of detail,visual mapping and light shadow generation are analyzed in detail.At the same time,the development of 3D simulation teaching function is completed by combining Adobe Premiere nonlinear editing technology,and the export process of 3D model is analyzed.(4)Based on unity3 d virtual reality development engine and Visual Studio development platform,the 3D scene roaming function,equipment wiring function and virtual operation function of the simulation system are developed.The particle system of unity3 d is used to develop the visual effects of smoke and flame when the accident occurs.Using C# programming language combined with My SQL database technology to develop the theoretical assessment function.The system has the characteristics of simple operation,rich content and strong immersion,which makes up for the shortcomings of traditional high-pressure experimental teaching method,improves students’ learning efficiency,ensures students’ learning safety,and has broad application prospects and promotion value.There are 82 figures,10 tables and 86 references.
