Based On The Design And Realization Of The Virtools Digital Circuit Experiment Teaching System

Experiment is an indispensable part of the popularization of science, higher education and distance education. These days, the experiment is conducted in the laboratory. So the mode of operation exists faults that are great input, great loss, the low efficiency, long life cycle, maintenance difficulties and dangers. The virtual experiment system appearing in computer technology as the foundation could assist for the experimenter to create simulation experiment environment.The virtual experiment teaching system is a kind of virtual experimental environment that Integrates of various techniques and tools of information, network. It is with great potential and good application prospect. At present, the virtual experiment teaching system is being used to be auxiliary or replace teaching partly. It has important practical significance for experiment teaching in ease pressure, improving the quality of experiment teaching.The main topic is about the design and the development of the Virtual Experiment System. We designed"the digital circuit experiment" virtual experimental prototype system according to"the digital electronic technology"experiment courses, for example. And specifically we developed "integration logic gate logic function test" virtual experiment that is also discussed on the teaching application effect.This article discusses the purpose and significance and elaborates the research background of virtual experiment. It introduces and analyzes the research situation of the virtual experimental system. And briefly analyses the virtual experimental research and application status of present professional education; Thoroughly discusses the theory basis for development of virtual experiment system, the meaning and characteristics of virtual experimental system, discussing the classification, technical background and the future direction of development of virtual experiment system etc, introducing and comparing the implementation technology of virtual experiment; analyzing the current characteristics and problems of experimental teaching of vocational education. With"integration logic gate logic function test"of the "digital electronic technology "experiment as an example, based on the Virtools 3ds Max software tools, which designing and developing the digital circuit virtual experiments, completely introducing the basic method of the systematic analysis, design and realize. Presenting the system business flowcharts, flow charts, module database structures, database designs, Web achieve key codes etc. We analyze some corresponding key technology and the development of virtual experiment method is discussed and summarized in this paper.Finally, we combine the experience of the individual in system development and the deficiencies of system .We do a simple prospect to be several aspects further study for the future work need.
