Design And Implementation Of 3D Electronic And Electrical Virtual Laboratory Platform Based On Web

With the rapid development of remote education,computer-assisted instruction has been implementing in more and more colleges.The construction of Internet-based interactive teaching system has become the focus of information technology and curriculum integration.Based on the actual electrical and electronic teaching environment,a design and implementation of Web-based 3D electrical and electronic virtual laboratory platform has been developed in this thesis using virtual reality theory and 3D modeling technology based on the comprehensive analysis of the needs of virtual laboratory users.Various functions of the network virtual laboratory are tested to complete the basic work for establishing and perfecting the network virtual experiment information management system.This thesis combines Java web technology with virtual reality theory.In the development process of the whole virtual laboratory,the virtual experiment teaching environment is constructed by using 3D modeling technology to simulate experimental devices.Secondly,the feasibility and demand analysis of the virtual experiment system was carried out,and the network virtual laboratory structure,required functional modules and database design were completed.Then,based on the B/S architecture,the system implementation of the virtual laboratory web platform is completed,which mainly completes the functions of user login and registration,student information management,experimental data management and student achievement management.Finally,the network virtual laboratory was tested for functionality to verify the final results of the lab development and ensure that the platform can accurately achieve the design goals.The virtual laboratory system implemented in this thesis is a web-based open experimental platform suitable for basic experimental courses in electronic information majors.Using this platform,users can learn electrical and electronic courses without being restricted by time and place.In addition,the system will display the experimental data in real time to the user in a visual way after the experiment is completed.Students can record the experimental data and submit the experimental data according to the teacher's requirements.Finally,the teacher can score the results of the experiment online based on the data submitted by the student.As a new type of experimental teaching,the experimental platform not only mobilizes students' enthusiasm,stimulates interest in learning,but also facilitates the efficient completion of experimental courses and ensures the effectiveness of teaching.
