Research And Development Of Electronic Technology Virtual Experiment System

Concept, ways and course of electrical experimentation are changed by computer simulation, EDA as well as virtual instrument technology. It has taken place traditionally hardware experimentation in many fields for the flexibility and low-costing.As rapid development of electrics related technology and information.Single mode of traditionally electrical experiment could’t undertake masks of electrics teaching, studying, and testing. Half of modern electrical experiment market already has been taken up by Simulation and virtual experiment (soft experiment). The best choice would be break down traditionally mode of experiment and develop new mode.After studying development model, development platfomms as well as key technology, a virtual experiment system that bases on prctise teaching of electrics in vocational technical college was established in this paper. Virtual instrumentation and virtual simulation were used in this system where most kinds of problemes of electrical practice teaching are solved.This system have characters as follow:1. According to the academic teaching of electrical experiment in Higher Vocational;2. Using Labview as a development platform;3. Theoretical difficulties and all of the experiment being classificated and carryiied out with different ways, such as presentation experiment being achived by cartoon or video presentation, verifying and testing experiment being achived by simulation and testing with virtural instrument, desiging experiment being achived by choosing component and desiging circuit;4. Preparing lessons befor experiment and generating laboratory report afer experiment;5. Many kinds of virtual instruments being frequently-used in order to process data and simulate circuit;6. The system combining advantages of using virtua instrument and using virtual simulation, As above’s illumination, this system is function enough for students.Finally, this paper summarized the performance of electrical virtual experiment system thourgh the course of system development, and it also demonstrated the main direction and content of optimizing and pefecting of this system.
