As an innovative part of teaching,

As an innovative part of teaching, virtual testing is a necessary and beneficial supplement to traditional practice, which can not only save a lot of education costs, but also effectively expand practice in time and space. The network virtual laboratory not only provides the technical support for the practice course teaching reform, but also saves the teaching resources. This course should use virtual experiment technology to build a remote virtual laboratory, which brings new vitality to it.In this course, based on MATLAB Web server technology, based on the original principle of the Web site virtual test room automatic control, Dreamweaver, Flash and MATLAB combined to become practical. The software and hardware of the customer machine should be low, easily extensible, and available for maintenance and upgrade. In addition, the student test can not be limited by time and space. Furthermore, Flash's powerful graphics capabilities and MATLA B's ability to mimic and analyze reality were fully utilized, which greatly shortened the development cycle of the process, resulting in a beautiful and well-performing interface with half the results. The main functions of the virtual laboratory are as follows:(1) network-based working energy. Installed and equipped with MATLAB Web Server, customers do not need to install MATLAB software, users do not need to understand MATLAB and master MATLAB programming, can use MATLAB. These should be used on the client side without maintenance, just maintenance and upgrades on the server side. No insertion is required.(2) aesthetic concept is based on practical operation. With the help of Dreamweaver powerful web page production capacity, the design system made a virtual virtual test room home page, and input into the output page li, the interface beautiful large grid, the content is complete, there are reasons, the user can be in the interface according to their own prompts to complete the test operation.(3) virtual quasi-reality test environment. Fl ash is used to construct virtual simulation scene to make virtual simulation instrument. Users can connect the virtual instrument according to the actual circuit diagram in the virtual simulation environment. The feeling of being with users greatly stimulates their learning and accumulation.Disadvantages of this virtual lab: virtual simulation tests developed by MATLAB Web Server cannot show real processes in real time, but only the end result of real processes, such defects and customer machines. Has to do with the server's communication latency over the Internet.In general, virtual simulation technology is a deep new technology with potential application potential in the development to meet the different needs of human beings. This subject has established a remote automatic control virtual reality laboratory. The completion of this course has improved my computer application ability and scientific research ability, laying a solid foundation for my future work. Objectively speaking, there are still some bad details in the virtual laboratory, and I hope to make further improvements in the next step.
