【Abstract】 On the basis of analyzing three common seen methods for the incremental encoder data acquisition, a new type of encoder data acquisition circuit is designed,and an eliminating disturbance software algorithm is presented.By using this encoder data acquisition circuit and the software algorithm the incremental encoder data acquisition is implemented.The algorithm eliminates vibrating and increases the maximum counting frequency.If the hardware circuit is designed by CPLD,the data acquisition of high speed and high precision incremental encoder could be obtained.更多还原
