Abstract:
Disclosed are a method and a device for detecting a moving distance and a storage medium. The method is applied to an automatic cleaning device including a moving wheel, in which the moving wheel includes a disk magnet disposed at a pivot center of the moving wheel and configured to rotate along with the moving wheel; the disk magnet includes at least one set of magnets, each set of magnets having two corresponding poles; the moving wheel further includes a Hall sensor configured to monitor a change amount of a magnetic field strength of each set of magnets in the disk magnet, and a movement trajectory of the Hall sensor is parallel to and synchronized with a movement trajectory of the pivot center of the moving wheel; the method includes: monitoring the change amount of the magnetic field strength of each set of magnets in the disk magnet, and outputting N pulse waveforms according to the change amount of the magnetic field strength of each set of magnets, wherein a value of N is associated with a rotation arc of the moving wheel, and N is a positive number, determining a rotation arc of the disk magnet according to the N pulse waveforms, and determining a moving distance of the moving wheel according to the rotation arc of the disk magnet.

Claim (Index 8):
The apparatus according to  claim 6 , wherein the second determining module is configured to inquire a stored correspondence relationship between pulse waveforms and rotation arcs according to the N pulse waveforms and determine the first rotation arc corresponding to a pulse waveform generated when the moving wheel rotates in the forward rotation direction and the second rotation arc corresponding to a pulse waveform generated when the moving wheel rotates in the reverse rotation direction in the N pulse waveforms.
