AI Technical Summary

Technical Problem

The protection logic of the roller brush motor in existing automatic cleaning equipment is prone to triggering protection when the roller brush motor is overcurrent, resulting in reduced equipment efficiency and poor user experience, especially when cleaning terrain with high resistance.

Method used

By collecting the operating current of the roller brush motor during the overcurrent detection cycle, the corresponding overcurrent counting strategy is determined, the overcurrent protection count and recovery count are updated, and the decision on whether to implement protection measures is made based on the count status, thereby reducing the number of times the roller brush motor overcurrent protection is triggered.

Benefits of technology

It effectively reduces the number of times the roller brush motor stops due to overcurrent, improves the working efficiency of automatic cleaning equipment, and enhances the user experience.

Abstract

The embodiment of the invention discloses a rolling brush motor protection method and automatic cleaning equipment, and the method comprises the steps: determining a corresponding overcurrent counting strategy according to the working current of a rolling brush motor in each overcurrent detection period; and determining whether to execute or stop the over-current protection measures according to the numerical value of the over-current protection counting updated by the over-current counting strategy and the execution state of the over-current protection measures, so that the triggering times of the over-current protection measures of the rolling brush motor can be reduced, the stopping times of the rolling brush motor due to over-current can be reduced, and the service life of the rolling brush motor can be prolonged. The working efficiency of the automatic cleaning equipment is improved, the use experience of a user is improved, and the technical problem that the working efficiency of the automatic cleaning equipment is reduced due to the rolling brush motor protection logic of the automatic cleaning equipment in the prior art is solved.
