Research And Realization Of The Experimental Scene Of The Virtual Circuit

The modern distance education is a new-type education form with the rapid development of the computer network technology and the modern information technology. Such interactive teaching form has become the trend of education by computer network .The modern distance education has advantages because it's open and flexible. It also broke the limitation of the education.But the technology of distance education is not matured especially in China.People have only made some Simple research,many key technologies are in the course of exploring and are still at the starting stage. The universities of China just have step into this field, most universities have only the service based on WWW. And now most of the virtual experiment teaching software are demonstrating system. The characteristic of this kind of software is lacking of the interaction of people and authenticity. This article designed the virtual experiment system through the problems and the request.lt can already have the accurate experiment result and have the characteristic of high interaction. Users can design the circuit like in the true experiment in the system and can carry on emulation, receiving the data result of emulation. This system can achieve the purpose of experiment teaching .Chapter one of this article carried on the survey of current situation of distance education and virtual experiment and proposed the goal of research in this article.Chapter two introduced the structure design of the virtual experiment system, especially introduced the system structure of electronic Circuits Scene. The electronic circuits scene is divided into six function modules, they are circuit design module, apparatus module, circuit saving and loading module, circuit check module , circuit board control module and control centre module.Users can complete all of the circuit operations by their transferring.Chapter three explained various kinds of key technologies which meet in this system. This chapter divide into five parts, which introduced the design of the scene, me circuit line-connect algorithnu the function of the apparatuses, the emulation controlling and communication protocol separately.The system can keep the newest state by the circuit line-connect algorithm. Users can participate in the circuit and get the result of the experiment by the apparatuses. Emulation control centre can control all of interaction. Communication protocol make the data be transmitted unobstructed.In chapter four we give an example of the experiment to show the scene and the experiment result.
