Roller washing machine cooperated eccentricity detecting system based on gyroscope

Abstract

The invention discloses a roller washing machine cooperated eccentricity detecting system based on a gyroscope in the technical field of driving control of a roller washing machine. The roller washing machine cooperated eccentricity detecting system based on the gyroscope consists of a power supply circuit module, a microcontroller, a filter, a three-axis gyroscope, a serial interface module, a display module, a variable frequency module and a driving motor. The acceleration generated in the work process of the washing machine is monitored through the three-axis gyroscope; the monitoring data is transmitted to a controller to be compared with the maximum set value allowed by the system; when the measured acceleration average value exceeds the set value, the variable-frequency module is used for regulating the rotating speed of the driving motor; the frequency causing the resonance is missed; the generation of serious shaking of a machine body can be eliminated.

Description

technical field [0001] The invention relates to the technical field of drive control of a drum washing machine, in particular to a gyroscope-based coordinated eccentricity detection system for a drum washing machine. Background technique [0002] With the development and change of science and technology, the functions of washing machines are also more complete and the degree of intelligence is higher. However, at present, most washing machines still use the method of calculating eccentricity based on speed fluctuations for eccentricity detection. However, sometimes because the speed fluctuations cannot directly reflect the eccentricity state of the washing machine drum, it will cause errors in judgment and cause the body to vibrate violently during the washing process. A lot of noise is then generated. This will not only affect daily use, but may also cause damage to the washing machine itself and shorten its service life in the long run.

However, at present, most washing machines still use the method of calculating eccentricity based on speed fluctuations for eccentricity detection, but sometimes because speed fluctuations cannot directly reflect the eccentricity of the drum of the washing machine, it will cause misjudgment, resulting in violent shaking of the machine during the washing process, and A lot of noise ensues

This will not only affect daily use, but may also cause damage to the washing machine itself in the long run and shorten the service life
