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 11):
A non-transitory computer-readable medium having stored therein computer programs that, when executed by a processor, cause the processor to perform a method for detecting a moving distance, applied to an automatic cleaning device comprising a moving wheel, wherein the moving wheel comprises a disk magnet disposed at a pivot center of the moving wheel and configured to rotate along with the moving wheel, wherein\n the disk magnet comprises at least one set of magnets, each set of magnets having two corresponding poles; and the moving wheel further comprises 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; and, wherein the method comprises: monitoring the change amount of the magnetic field strength of each set of magnets in the disk magnet; 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 direction of the moving wheel according to a voltage value corresponding to the N pulse waveforms, wherein the rotation direction comprises a forward rotation direction and a reverse rotation direction; 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; wherein determining the rotation arc of the disk magnet according to the N pulse waveforms comprises:\n determining a first rotation arc when the moving wheel rotates in the forward rotation direction and a second rotation arc when the moving wheel rotates in the reverse rotation direction; and \n combining the first rotation arc with the second rotation arc to obtain a result and taking the result as the rotation arc of the moving wheel.
