Abstract: Disclosed are an encoder signal sampling method and device, relating to the technical field of servo control. The method and the device comprises: acquiring a data frequency of an encoder, determining a clock frequency according to the data frequency, then generating a high-frequency clock signal based on the clock frequency, then sampling an input signal of the encoder by taking the high-frequency clock signal as a reference so as to obtain a sampled signal, and finally carrying out denoising on the sampled signal based on a preset algorithm by utilizing a processor. By sampling input signals of an encoder by using a high-frequency clock signal, more sampling points may be obtained, so that enough signal samples are obtained for subsequent data analysis and denoising processing; the proportion of effective signals in the signal samples is obviously higher than that of noise signals under the effect of the high-frequency clock signal, so that the influence of the noise signals on the sampled signals is smaller, and therefore the accuracy of the sampled signals is guaranteed.
