Experimental Platform Based on LabVIEW
ABSTRACT
With the development of computer traditional instrument has developed into
computerize instrument. Virtual Instrument is a perfect combination of modern
computer technology instrument technology and other new technology. Its strong
function is beyond the instrument itself. Physical lab is important component of teaching
system in colleges and universities and plays the key role in training the students"
scientific characters, experimental skills and creative capabilities. This project has
established the example to introduce the virtual instrument technique into traditional
practical physical lab. Using virtual instruments in the physical experiments will help to
reform traditional experimental teaching. The virtual physical lab can train the students"
ability to master the scientific and technological knowledge and experimental skill,
strengthen the students" creativity and eventually improve the students" comprehensive
quality. I use modular method and many papers to describe the whole building process，
analyze and solve issues which come forth during the design and realization process。As
the conclusion, I offer the theories, panels and diagrams of eight virtual instruments,
such as virtual sine wave generator, autocorrelation function demonstrator, phase
difference demonstrator based on phase method, virtual sine wave frequency spectrum
analytical instrument, and a example program which used in the practice．These virtual
instruments form the teaching test system。Which can be used in experimental courses,
for example, circuit theory, electronic technical basis, signal and system ,automation
control theory and soon．
Keywords: LabVIEW programme, comprehensive experimental platform,
