Abstract

The invention relates to a pull rope type strength training instrument protection method and device and a strength training instrument, and the method comprises the steps: obtaining the rotating speedof a motor, judging whether the motor is in a stalling state or not according to the rotating speed of the motor, determining the stretching condition of a pull rope, and judging whether the physicalstrength of a user reaches the limit or not; obtaining a torque estimated value by inputting quadrature-axis current and rotating speed of a motor into a torque observer, judging whether a user outputs tension to a pull rope or not by comparing the torque estimated value with a set threshold value, and aiming at the condition that the physical strength of the user reaches the limit, adjusting theoutput torque of the motor to be a preset protection torque, so the pull rope is prevented from being rapidly withdrawn due to the fact that user tension is smaller than motor output load torque, andusers are prevented from being injured.

Description

technical field [0001] The invention relates to the field of strength training equipment, in particular to a protection method and device for a pull-cord type strength training equipment and the strength training equipment. Background technique [0002] With the continuous progress of society, people's living standards have been greatly improved, and people are paying more and more attention to sports and fitness. Pull rope type strength training equipment protection is a common fitness equipment. When in use, the motor output load torque is controlled as the load force recovered by pulling the pull rope. Opposite pull for strength training. [0003] However, during the training process, if the motor continues to output a large load torque when the user is physically weak, the pull rope is quickly retracted at this time, which is likely to cause injury to the user. Contents of the invention [0004] The embodiment of the present application provides a protection method a...
