Study And Development Of Web-Based Virtual Electronic Component Library

With the development of education, experiment has been an indispensable part of teaching. But the laboratories of many high schools have the problems such as old experimental equipments and lacking of financing, and can not satisfy the need of the expansion of enrollment currently. So, it is necessary that achieve the experiment education standards by network and virtual experiment environment. Especially in circuit analysis experiments, various experimental apparatuses and complicate operation environment are indispensable. With the application and development of the virtual reality technology, it will have a good foreground to complete a virtual network circuit analysis system.To solve the above problems, through the analysis and comparing the prevalence of Electrical and Electronic Virtual Experimental Software Components of the solution, this paper has brought up and achieved a web-based virtual integrated development environment of components which is against Circuit Analysis experiments. The solution of the server is using Java Servlet technologies and PSpice software to analysis the requests from client. The components library has designed those basic components such as resistors, capacitors, inductors, transistors, voltage source, Current sources, also including some complex circuit devices such as MOS transistor and Integrated Operational Amplifiers. Different components can be deposited in the different component library and user can select different needed components from different.The Components Library of this paper has good expandability, which support dynamic customization and the expansion of virtual components. Users can use the dynamic customization provided by this system to add components, delete components or change component's properties. So it is easy to use and maintains.
