Counting method and device based on incremental encoder

Abstract

The invention belongs to the technical field of motor encoders, and particularly relates to a counting method and device based on an incremental encoder, and the counting method comprises the following steps: S1, enabling an output shaft of a motor to pass through the center of an encoder body, enabling the output shaft of the motor to coincide with the axis of the encoder body, attaching one side of the encoder body to the side wall of the motor, and then setting an output pulse signal of the encoder; and S2, recording a signal obtained by rotating the motor shaft clockwise through a pulse signal as a signal I, recording a signal obtained by rotating the motor shaft counterclockwise through a pulse signal as a signal II, and outputting the signal I and the signal II to a display in sequence. By dustproof elastic cloth, the encoder body can be attached to the encoder body in the using process, and the problem that impurities outside the encoder body enter the encoder body, and consequently optical counting of the encoder body is affected is solved.

Description

technical field [0001] The invention belongs to the technical field of motor encoders, in particular to a counting method based on an incremental encoder and a counting device thereof. Background technique [0002] The encoder is composed of a grating disk and a photoelectric detection device. Since the grating disk and the motor are coaxial, the grating disk and the motor rotate at the same speed. The light-emitting diode illuminates the grating disk and projects the image of the grating disk onto the photoelectric detection device composed of photosensitive elements. The light changes generated by the rotation of the grating disc are converted and output as corresponding pulse signal changes. [0003] There are also some technical solutions for motor encoders in the prior art. For example, a Chinese patent with application number 2021200737511 discloses an incremental encoder with a through-shaft hole, including an encoder body. A shaft hole is provided with a clamping pa...
