Design and implementation of sensor’s experiment based on virtual instrument

Expatiating the advantage and feasibility of the application of virtual instrument in sensor’s experiment, discussing on how to utilize virtual instrument for designing of sensor’s experiment. The problems such as single function of traditional experimental platform, complex operation, bad expansibility and etc ,The author brings forward a proposal of using existing CSY sensor instrument to develop a LabVIEW based experimental system. Detailed analysis of testing theories, design scheme which based on the virtual instrument system, hardware configuration and test implementing route are provided for the testing of a motor’s rotation speed. The results show that the experimental system is easy to handle , friendly to communication and high accuracy.
