The Design And Implementation Of Virtual Experiment Simulation System For Computer Interface Based On VC

With the deepening reform of higher education and the rapid expansion of enrollment, Universities in China generally fall into the plight of the experimental teaching. Mainly in the lack of hardware facilities, teaching methods and content of the backward areas of teaching by the time and space constraints. In the rapid development of computer and multimedia technology, virtual experiment system full use of computer resources, to solve these issues and improve the quality of teaching experiment, has become an important choice.Based on the development of virtual experiments in the status and trends, for experimental teaching requirements and the existing lack of virtual experiment system, thesis presented the system design of "Virtual Experiment Simulation System of Computer Interface" and carried out specific research and design on the key technologies.Firstly, object-oriented simulation and modeling methods were introduced. Then, Proposed by using methods based on object-oriented simulation modeling system for simulation modeling. By analyzing real experimental process and requirements, Simulation Modeling of virtual devices, virtual connection and virtual experiment were conducted.By UML modeling language, Thesis driven by use cases and described from different perspectives and levels of the system's static structure and dynamic behavior by using class diagram, sequence diagram, activity diagram and so on. With the use case model and analysis model, based on design class diagram, the further refinement of these classes to obtain a more detailed description of the class, the main function of the implementation class method, lay the foundation for the system implementation. Detailed description of the main class in system and implementation method of the system operator interface.Finally, the virtual experimental system described in detail the key issues-the running control of simulation experiment. Simulation experiment run control is the most important part in virtual simulation system experiment, which includes the connection algorithm between the device and signal transmission algorithm between the device. Through the analysis of existing algorithms, devices connected and signal transmission algorithms, combined with the characteristics of the experimental system proposed for the system connection and signal transmission algorithms.The implementation of "Virtual Experiment Simulation System of Computer Interface" help to solve the problems in computer interface experiment. Deepened the understanding of "software instrument" or "software components", and trained creative ability of students.
