Design And Implement Of Web-based Virtual Experiment

The leap-style development of computer network technology,simulation technology and virtual instrument technology has provided the technical foundation for the reform of experimental teaching in colleges and universities.Virtual laboratory will be to a certain extent,improve the lack of traditional college experimental resources and other issues,This paper designs a Web-based virtual laboratory system.After the experimental network,users anywhere through the network can operate the experiment on the simulation platform.Virtual lab system adopts B/S structure model,which has the advantage that the user can access it by using the browser.In the process of developing the system,this article uses eclipse as a development tool,Tomcat7.0 as a server,the background of the database using MySQL5.0,and selecting the current main stream JSP technology to research and develop.The virtual laboratory system researched in this paper is an open experimental platform based on Internet,which is suitable for the experimental operation demonstration of the basic course of electronic information specialty.In the whole development process of the virtual laboratory system,the feasibility analysis and requirement analysis of the system are carried out according to the current research situation.Then the whole structure of the system and the functional modules of the system are designed;Secondly,the detailed design and implementation of the system function module is carried out according to the overall design of the virtual laboratory system.Virtual laboratory system is divided into virtual experiment management platform and virtual experiment simulation platform.Virtual experiment management platform mainly achieves the user registration,login,and reservation,querying the status of the experiment information and personal information,and other functions.The virtual experiment simulation platform realizes the online experimental operation function of the digital signal processing course,and can write the experimental report submitted to the background.In general,the development of virtual laboratory system can save experimental save the experimental manpower and material resources.In addition,it is easy to management and good for experimental teaching,which not only mobilizes the enthusiasm of students and stimulate their interests,but also more conducive to efficiently complete the experiment,so as to ensure the effect.The virtual lab can be accessed in any browser,requiring only users to be able to access the web and know the server's address.As a result,the virtual lab system has great portability,stability,and security.
