Research On Virtual Experiment Platform Based On Flex

With the rapid development of computer technology, network virtual experiment system has been able to deal with the help of modern communication and information technology to their students a more realistic test experience. Compared with traditional laboratory Virtual Lab with low investment cost, no loss, easy maintenance, update speed, easy to repeat the experiment under the same conditions, easy to expand and share the advantages. The virtual experiments platform has gradually become a popular research direction.First, the paper introduces the research background and remote network of virtual research experiments, and analyzes the current situation of research on remote network virtual laboratory at domestic and foreign.Secondly, the paper uses Struts2+Spring+Hibernate Java framework as a remote network virtual experiment platform back-end technology, use the MVC design model to organization code,separate the method of business logic, data interface displays to organization code.The front-end using Flex as a development language, the use of event-driven framework to develop experimental systems Cairngorm framework UI interface. Using MySQL as a database to store the experimental data.Again, the paper designed and developed a virtual signal generator, a virtual oscilloscope, virtual resistors, circuit boards and other components of virtual experiments. And these components are constructed based on virtual simulations, virtual signal and system experiments, virtual communication experiment three experiments. To meet the basic needs of teaching. Remote network virtual experiment platform maximum degree of reduction of the cost of funding for experimental research.Development trend of comprehensive domestic and foreign virtual experiment platform, browser-based B/S virtual experiment platform to become the new direction of development. This paper presents a new virtual experiment platform design that SSH framework and virtual experiment platform-based design methodology Flex. Truly independent of time, place, instrument limited experiment. Students can complete an independent experiment.
