Method and system for electric lifting table to retract while meeting resistance based on self-learning, and lifting device

Abstract

The invention provides a method and system for an electric lifting table to retract while meeting resistance based on self-learning, a lifting device and a medium. The system comprises a self-learningapparatus and an apparatus for retracting while meeting resistance. The self-learning apparatus obtains a parameter characteristic value of a lifting component, and obtains a tightness degree changearea according to the parameter characteristic value; and the apparatus for retracting while meeting resistance obtains a motor dynamic parameter value, corrects the motor dynamic parameter value in the tightness degree change area to obtain a corrected motor dynamic parameter value, and executes retraction while meeting resistance according to the corrected motor dynamic parameter value. By adoption of a self-learning algorithm, the interference of the motor dynamic parameter value caused by the consistency difference of the lifting component is eliminated, the consistency deviation of the lifting component caused by production process and fatigue after multiple times of use can be eliminated, and the wrong trigger of retraction while meeting resistance is avoided from the root cause, sothat the sensitivity of the retraction while meeting resistance and the usability of the function of retraction while meeting resistance are greatly improved, the production consistency requirements of the lifting component are reduced, and the production cost of the lifting component is reduced.

Description

technical field [0001] The present invention relates to the field of lifting equipment, in particular to a self-learning-based method and system for retracting an electric lifting table in case of resistance and lifting equipment. Background technique [0002] As people spend more and more time sitting and working, people gradually realize that sitting for a long time is not conducive to the improvement of work efficiency. Office has become a popular way of healthy office. Electric lift tables generally use electricity as the power source, and the height of the lift table can be adjusted by controlling the mechanical device through the motor, or the height of the lift table can be adjusted by controlling the air pressure rod or hydraulic rod through the compressor. [0003] At present, the mainstream electric lifting tables in the market have single table legs, double table legs, three table legs and four table legs, which are controlled by 1 to 4 motors respectively, and t...
