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 13):
The non-transitory computer-readable medium of  claim 11 ,\n wherein determining the first rotation arc when the moving wheel rotates in the forward rotation direction and the second rotation arc when the moving wheel rotates in the reverse rotation direction comprises: inquiring a stored correspondence relationship between pulse waveforms and rotation arcs according to the N pulse waveforms and determining 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.
