The Design Of Virtual Electronic Experimental System

Along with the swift development of the computer technology and multimedia technology, the virtual emulational experiment technology rises rapidly; the main application in teaching field is virtual experiment. Its characters of the high emulation are popular used in the area of virtual experiment. The virtual experiment used in the electronic technology area is called virtual electronic experiment. Virtual electronic experiment is what students who use computer simulation technology in order to design, simulate and debug the circuit that must be completed in the lab before, in order to learn simulate circuit and numeral circuit. A computer that joined into Internet, a set of electronic computer emulational software, and an experiment course equal to be an advanced equipment of the lab, students can easily finish the experiment course requirements by it.Experimental teaching is the important part in the electronics teaching. For many years the traditional experimental methods play an important role in students' learning the basic theories, basic knowledge, basic skills, and trains the students'ability of analyzing and solving the questions. Because of the rapid development of science and technology, the society needs more and more talents, who not only should have more rich knowledge, but also should have stronger ability about the application and the innovation of knowledge, in order to adapt the demands of the new situation. Virtual reality technology applied to traditional experimental teaching, as a necessary and beneficial supplement of experiments, which can save a supplement of education funds, also made experiments on time and space effectively outspread, therefore, to cultivate students' innovation consciousness and practice ability are significant.The deepening of the reform of the teaching which puts forward higher request of experiment teaching in order to developing students' scientific research ability and integrated quality. Teaching content, teaching mode, and the teaching method of experiment teaching need to be innovated urgently. The maturity and development of the virtual experiment technology and the stringent reform of the experiment teaching make the application of virtual experiment teaching from the theoretical research into the actual application.The thesis includes the following main aspects: First, the study about the design of virtual electronic experimental system based on the theoretical analysis of the virtual nature of electronic simulation software, and the use of Multisim simulation software design and implementation 10 basis experiment of analog circuits and digital circuits, and then set up a simple web-based platform for experimental study guide - a virtual electronic experimental system, which is the electronic experiments of teaching and teaching reform experiment has a positive meaning.The thesis is on innovative pilot projects through virtual design of electronic visual image of the display used in electronic experimental teaching Multisim especially analog circuits and digital circuits of the advantages of teaching. Multisim Electronic Experiments in Teaching, in order to reduce experimental costs and update equipment to accelerate the speed of the innovative spirit of students provided technical support.However, the development of virtual electronic paper experimental system only online collaborative learning autonomy and the simple application of the requirements from the virtual laboratory are still gaps. In addition, after the adoption of the system of teaching is also a lack of quantitative assessment of the effect of the guidelines, specific guidelines for the assessment of need in the future the practice of continuous improvement in teaching. Therefore, future experiments need to create a virtual environment, online completion of experiments the effect of assessment to be perfect. This paper discusses the virtual experiment of teaching the theoretical basis for the new teaching techniques used in the experiment to find a theoretical basis. As a result of many factors, Multisim simulation software will be the introduction of analog circuits, digital circuits to support teaching both in theory and practice are the process of initial exploration, and there is no complete theory or well-established modes of teaching, these areas need in future to improve teaching practice and improve.
