The Design Of Campus Virtual Experiment System Based On Grid Technology

The thesis first briefly introduces the development application circumstance of grid technique and virtual experiment technical, emphasizing to elaborate the creation, domestic and international development condition of the virtual experiment and virtual laboratory, and aiming at the present concrete circumstance of the laboratory, puts forward the necessity and the meaning of this research. Whereafter taking computer technique, grid technique, virtual instrument technique as a basis, this paper puts forward the speculation that sets up virtual laboratory, namely replacing hardware with the software, using program to imitate whole processes of experiment, then constructs the grid technical based campus virtual experiment system on the foundation of the virtual laboratory. Choosing Browser/Server system structure, via the analysis and comparison of the characteristics for two kinds of network structure: the Browser/Server and Client/Server. Through the analysis and comparison to some key techniques and the software tool of the virtual laboratory at home and abroad, this thesis puts forward a set of bran-new solution, adopting the mode of .NET technique,the grid technique, virtual instrument technique and so on to combine together. This kind of technique is better than other technique for its simpleness, agility, object oriented, type safety, virtual instrument development and so on. According to the design principle and target of the virtual laboratory, the function, module, system flow and so on of the system are carried on analysis, the thesis analyzes the software,hardware constitution and demarcation of each function module of the virtual laboratory, and carries on a design to the client and server of the virtual laboratory, and then the software,hardware constitution and demarcation of each function module of the campus virtual experiment grid are carried on analysis, and carries on a design to the client and server of the virtual experiment system. According to the design principle and target of the grid virtual laboratory, this thesis carries on analysis to the function,module,system flow and so on of the system, completing the design of the campus virtual experiment system. This research is not only a virtual experiment system of integrity but also a leading foundation research, the purpose is that investigates the basic system structure, key technique and realization technique of the virtual experiment system, the design of the virtual instrument sub-system, and the frame solution, thus settles foundation for the new step of education quality in experiment teaching , network education and so on in each college and university.
