Research on Adaptive Measuring Method of Rotational Speed for Tire Drum Tester
2009
Two speed measurement methods based on pulse signal of the photoelectric encoder were introduced and the precision of multi-period method was analyzed.On this basis,an adaptive method suitable for the whole speed range with higher precision was presented.The structure of rotational speed measuring system was designed based on MSP430F149 microprocessor.The hardware system and the software implementation of adaptive method were expounded.The adaptive measuring method of rotational speed for tire drum was implemented.
