The Research And Implementation On Rapid Development Of Virtual Practice Course

Device simulation system under virtual practical training system provides a creative idea in the search for rapid development of virtual experiment course,it’s designed by the theory of finite state automata. The virtual experiment platform developed under virtual practical training is divided into two parts, as part of the acquisition and storage of experimental data, and the other part is generated based on the experimental data show that the experiment. For the internal logic and principles of the experiment did not go into this development model, but will mainly focus on the performance of the experimental process, what kind of operation that will produce what kind of change in the course of the experiment, this is a for all device emulation mode can be common.This virtual experiment model development, although in external performance and situational immersion of speaking is not a traditional virtual experiments is high, but in view of the development efficiency has greatly improved over traditional virtual experiments, and therefore for the update speed, the principle of the content requirements the device is not too high is a very good choice.At present, the development of virtual experiment platform virtual practice process experimental data acquisition and storage part by teachers and curriculum developers to complete the cross found in the experimental test development process of this cross-cutting work processes often due to convergence problems led the experiment curriculum development cycle extended.This study using C#and Visio development technology to develop a graphical virtual experiment platform for creating flowcharts teachers make experiments and describe the properties of each state by dragging the drawing operation, the platform automatically get to the experimental curriculum development need the appropriate data and writes the data in the database for device emulation system calls to generate experiments. Through the system was originally changed from teachers and developers work accomplished teachers cross alone. Through this system, virtual practical training system in terms of the efficiency of acquisition and storage of experimental data have been greatly improved, practical platform for virtual "mass production" experimental course provides fast data support. Rapid development tools will also be developed for data processing and experimental courses converge into a unified platform for unified storage and laboratory experiments upgrade also provides centralized management of the environment.The software for WINDOWS environment,its using C#development, graphics module using embedded Visio drawing com components, users draw flowcharts experiments and experimental data in the drawing module, the software will automatically save to a database of experimental data.Proven testing and updating software now has basically reached the requirements.
