Research on the multi-function dynamics experimental system based on the virtual instrument

The multi-function remote dynamics experiment system based on the virtual instrument is studied. The system can acquire and analyze the signal of infrared pair tube and relay by the technology of virtual instrument and the software of LabVIEW, so that the real-time monitoring and the adequate data analysis of the movement trace of objects can be realized. By this system, not only the students can learn the physics knowledge much intuitively and effectively, but also the teachers can get twice the result with half the effort in the physics teaching.
