Problems solved by technology
For the first method, in the dehydration stage, when the eccentricity is large, there may be abnormal noises in the mechanical impact switch, and this method not only cannot actively identify the eccentricity, but also has a certain probability that the door switch cannot be broken. Poor; for the second method, the motor current and torque will be affected by other interference factors, which will easily cause eccentricity perception errors

The invention provides a washing machine eccentricity sensing method and system, a washing machine, a computer device and a computer-readable storage medium. The washing machine eccentricity sensing method comprises: after the washing machine enters a spinning procedure, controlling a tub of the washing machine to rotate at a preset speed; acquiring a motion trajectory of the tub through a cameraof the washing machine; judging whether the motion trajectory of the tub exceeds a preset motion range; if not, controlling the tub of the washing machine to run at the highest speed to carry out spinning. Eccentricity is recognized actively herein; spinning is carried out when eccentricity is within a reasonable range; therefore, spinning difficulty of the washing machine due to excessive eccentricity occurred in the spinning stage of the washing machine is avoided, intelligence level of the washing machine is increased, and market competitiveness of the washing machine is improved.
Description
technical field [0001] The present invention relates to the field of washing machines, and more specifically, to an eccentricity sensing method and system for washing machines, a washing machine, computer equipment, and a computer-readable storage medium. Background technique [0002] At present, there are very few eccentricity sensing methods for pulsator washing machines on the market. Most of the eccentricity sensing methods are adopted by most products. One is to determine the eccentricity by hitting the door switch in the inner drum of the washing machine to avoid displacement and vibration caused by excessive eccentricity during dehydration. The second is to determine the eccentricity by the current or torque of the motor in the dehydration stage of the washing machine, so as to judge the working state of the washing machine in the next stage according to the eccentricity. For the first method, in the dehydration stage, when the eccentricity is large, there may be abno...
