AI Technical Summary

Technical Problem

Urban rail transit floor cleaning equipment suffers from uneven cleaning power due to uneven wear of the brush bristles, resulting in reduced cleaning effectiveness and increased manual intervention.

Method used

By collecting the motor load information of the driving cleaning brush in real time, performing frequency analysis, identifying the non-uniform wear state of the bristles, and adaptively adjusting the closed-loop control parameters of the motor or superimposing compensation signals to offset the load fluctuations caused by wear.

Benefits of technology

This achieves uniform cleaning force on the floor throughout the entire rotation of the cleaning brush, reducing manual intervention, lowering operating costs and the workload of maintenance personnel, and improving the autonomy and efficiency of automated equipment.

Abstract

The present application relates to the technical field of urban rail transit floor cleaning and maintenance equipment control, and provides a kind of urban rail transit floor cleaning and maintenance equipment control method and system, by real-time acquisition of the load information of motor driving cleaning brush disc and frequency analysis is carried out, identify the load fluctuation characteristics related to the rotation frequency of cleaning brush disc;According to the amplitude and phase change of load fluctuation characteristics, determine that the bristles of cleaning brush disc are in non-uniform wear state, adaptively adjust the closed-loop control parameters of motor / overlap the compensation signal synchronous with the rotation angle of cleaning brush disc in the control command of motor;The motor is controlled by the adjusted closed-loop control parameters and / or control command of motor, so as to dynamically optimize the motor control according to the actual wear condition of bristles, so that the cleaning force applied to the ground by the cleaning brush disc remains uniform during the entire rotation process, significantly improving the cleaning quality.
