Control method of exercise device using cable

Abstract

A control method of an exercise device using cable is proposed. The control method of an exercise device according to the present disclosure may include a posture detection step at which whether posture is incorrect is detected. Additionally, the control method of an exercise device according to the present disclosure may include a load decrease step at which an exercise load is decreased when incorrect posture is detected at the posture detection step. Accordingly. it is possible to prevent the occurrence of accidents by detecting that a user's posture is incorrect.

1 . A control method of an exercise device using cable, the control method comprising:
 a load input step at which a target load is input;   a load increase step at which an exercise load is increased in such a manner that the target load is transmitted through the cable;   a posture detection step at which whether posture is incorrect is detected while the exercise load is increased at the load increase step; and   a first load decrease step at which the exercise load is decreased when incorrect posture is detected at the posture detection step.   
     
     
         2 . The control method of  claim 1 , wherein the posture detection step comprises:
 a speed detection step at which a moving speed of the cable is detected, and   an incorrect-posture determination step at which it is determined that posture is incorrect when the moving speed exceeds a preset threshold speed.   
     
     
         3 . The control method of  claim 1 , wherein the posture detection step comprises:
 a position detection step at which a present position of the cable is detected, and   an incorrect-posture determination step at which it is determined that posture is incorrect when a distance between the present position of the cable and an initial position of the cable exceeds a preset threshold distance.   
     
     
         4 . The control method of  claim 1 , wherein at the first load decrease step, the exercise load is reduced to a pre-registered basic load. 
     
     
         5 . The control method of  claim 1 , further comprising: an initial detection step at which whether a position of the cable is moved to an initial position of the cable for exercise is detected,
 wherein the load increase step is performed after movement of the cable to the initial position of the cable for exercise is detected.   
     
     
         6 . The control method of  claim 1 , further comprising: an alarm output step at which a guide alarm is output to induce posture correction when incorrect posture is detected at the posture detection step. 
     
     
         7 . The control method of  claim 1 , further comprising:
 a pull detection step at which pulling speed at which the cable is pulled from a user is detected in a process in which exercise is performed in a state in which the exercise load transmitted through the cable reaches the target load, and   a damping adjustment step at which damping force applied when winding the cable is increased when the pulling speed exceeds a preset dangerous speed.   
     
     
         8 . The control method of  claim 7 , wherein the dangerous speed is preset in inverse proportion to the target load. 
     
     
         9 . The control method of  claim 7 , wherein the damping force is adjusted in proportion to the target load. 
     
     
         10 . The control method of  claim 1 , further comprising:
 a position detection step at which a final position to which a user pulls the cable is detected in a process in which exercise is performed in a state in which the exercise load transmitted through the cable reaches the target load, and   a second load decrease step at which the exercise load transmitted to the cable is decreased from the target load when the final position decreases.   
     
     
         11 . The control method of  claim 10 , wherein the second load decrease step is performed when the final position continuously decreases a preset number of times or more. 
     
     
         12 . The control method of  claim 11 , wherein at the second load decrease step, the exercise load is decreased in proportion to a rate of the decrease of the final position.
