Aiming at the problems in the speed test of in-use mine transport equipment,a non-contact speed measurement system based on photovoltaic technology and LabVIEW has been developed.The system can obtain signal power spectra and real-time speed by using LabVIEW spectrum function for real-time analysis of signal data.Comparing with the calibration device,the non-contact speed measurement system is stabile in measuring,has good real-time,its deviation in speed is less than ±0.2km/h,it can display speed curve in real time,automatically calculate acceleration and deceleration,and print the measurement data and results on-the spot.It provides a new way to test the seep of in-use mine transport equipment.
