| As an important supplement of formal college education, modern distance education has a strong demand from the market. With the popularity of IPv6 network in China, the need for the distance education system applications which support the next generation internet becomes urgent. As an important part of distance experiment education, distance education on electronic circuits is still on its beginning. There are few practical online electronic simulate systems with appealing interface on the internet, and obviously the need of distance education on electronic circuits can't be meet, not to mention the systems on IPv6. So the remote experiment system has a great potential for improvement.According to the previous description, focusing on electronic circuits experiments, this paper designed and implemented a remote virtual electronic experiment system based on existing virtual reality, networking and simulating technologies. This system, which is built on B/S Model, implemented an virtual environment of remote electronic circuits experiment, and it supports both digital and analog circuits experiment with real-time response and good user experience. As the simulation engine, Spice Opus provides accurate simulation results and thus the system's correctness is guaranteed. This system supports IPv6 network with backward compatibility with IPv4, so the demand of distance education applications over IPv6 is met.By utilizing Apache HTTP server and web browser as the communication layer, the communication is simplified and the whole system becomes more compact, besides it can also serve over firewalls. Thanks to APR, better portability is achieved.Client uses Flash technology to provide its user interface, so it can support various platforms and it's easy to be deployed. With the excellent graphics and interaction performance of Flash, the system provides a good immersion to users.This system can be used for distance education on electronic circuits experiment, as while as be used as the preview and review tool for students, so the application prospects are wide. |
