Abstract


This article analyzes the colleges and universities teaching in the electronic professional teaching practice characteristics. In the university teaching process, they often use expensive test chambers with special software to carry out the teaching purpose. This form of system can’t compatible with a variety of interface. And because of its weakness of single function, the use of test chambers as an experience equipment has been reduced largely. Especially in the signal analysis area, Teachers are unable to show the students that the relation between math function and waveform.The DAQ system teaching instrument developed base on Lab VIEW is practical, flexible, expandable for teaching purpose. Its hardware can be split to several function module circuits, and can be explained conveniently for teacher. Its software can directly control data flow which can show the textbook formulas directly and vividly in image, and students are convenient to understand. These works below has been done in order to finish the design:1. Research of virtual instrument. The virtual instrument is developed based on Lab VIEW to drive the communication between COM port on PC and DAQ hardware.2. Research of DAQ hardware. DAQ board is split into signal conditioning module and DAQ controlling module which is controlled by SCM.3. Research of teaching instrument. The DAQ system teaching instrument that is developed by using Graphical Programming Language and SCM can meet the needs for practical teaching.
