Self-learning-based method, system, and lifting equipment for electric lifting table to fall back in case of resistance

Abstract

The invention provides a self-learning-based method and system for an electric lifting table to fall back in case of resistance, lifting equipment, and a medium, including a self-learning device and a fallback device in case of resistance. The self-learning device obtains the characteristic value of the parameters of the lifting components, and obtains the change area of ​​the degree of tightness according to the characteristic value of the parameter; the retreat device obtains the dynamic parameter value of the motor in case of resistance, and corrects the dynamic parameter value of the motor in the change region of the degree of tightness to obtain The corrected motor dynamic parameter value; implement resistance fallback according to the corrected motor dynamic parameter value. The self-learning algorithm is used to eliminate the interference of the dynamic parameter value of the motor caused by the consistency difference of the lifting parts, which can eliminate the deviation of the consistency of the lifting parts due to the fatigue of the production process and repeated use, and avoid the root cause of the resistance and retreat Mis-triggered, thereby greatly improving the sensitivity of the resistance fallback and the availability of the resistance fallback function, and reducing the production consistency requirements of the lifting parts and reducing the production cost of the lifting parts.

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...

Problems solved by technology

This method also has two major disadvantages. One is that the production cost increases and the yield rate decreases, which is unacceptable for the civilian field; Potential for preventing fallbacks from being falsely triggered
