SWING SPEED AND LOCUS MEASURING DEVICE FOR MEASURING SWING SPEED AND CONSECUTIVE LOCUS WITH SMALL NUMBER OF SPREAD BEAM

摘要

PURPOSE: A swing speed and locus measuring device is provided to measure the swing speed and the consecutive swing locus using a small number of spread beam. CONSTITUTION: The swing speed and locus measuring device comprises a beam transmitter for generating a spread beam crossed the direction of the swing; a beam receiver(104) receiving the spread beam using multiple beam detecting sensors(D1-Dn) and a data processing unit(106) connected to the beam receiver(104); A status data of the beam detecting sensor is passed to the data processing unit(106) for the time interval. The data processing unit(106) calculates the location of the swing using the status data of the beam detecting sensors and measures the swing locus and speed using the data of the location and the time interval.
