Human-body-exercising-running-machine self-adaption active control method based on CPG model

Abstract

The invention discloses a human-body-exercising-running-machine self-adaption active control method based on a CPG model. The human-body-exercising-running-machine self-adaption active control method includes the steps that surface electromyographic signals of the lower limb rectus femoris and biceps femoris muscles in a gait cycle are collected in real time through an electromyographic collecting apparatus when the human body moves on a running machine, and the amplitude characteristics and the frequency characteristics are extracted; the amplitude characteristics and the frequency characteristics serve as the parameters to be substituted into the CPG model optimized by the genetic algorithm, and a periodicity-human-body-lower-limb hip joint angle curve is fitted; according to the periodicity-human-body-lower-limb hip joint angle curve, the angle extreme value and the frequency are obtained and substituted into a relationship model to obtain a speed control command of the running machine, the speed control command of the running machine is sent to a driving module though a computer, and self-adaption active control of the running machine is achieved. According to the human-body-exercising-running-machine self-adaption active control method based on the CPG model, the amplitude-frequency characteristics of the human-body lower-limb sEMG are extracted to serve as the parameters of the CPG model, the expected periodicity hip-joint gait curve is obtained, the angle extreme value and the frequency are extracted, a speed command of the running machine is obtained through the relationship model, and self-machine self-adaption active control, and self-adaption active control of the running machine is achieved.

Description

technical field [0001] The invention relates to the technical field of fitness equipment, in particular to an adaptive active control method for a human body exercise treadmill. Background technique [0002] With the improvement of material living standards, more and more people begin to care about their own health and become keen to participate in various sports exercises. The global fitness equipment industry has also developed rapidly. Among them, treadmills are easy to operate and small in size. Space-saving, it meets people's needs for aerobic fitness, has broad development space and development potential, and has become one of people's main fitness equipment at present. [0003] However, during the use of the treadmill, the runner must be forced to adjust his own speed to adapt to the preset fixed speed of the treadmill, which seriously affects the initiative and ease of the runner when exercising, and also limits the application of the treadmill. . Therefore, a tech...

AI Technical Summary

Problems solved by technology

This method needs to detect the displacement parameters of the human body, and is suitable for use on large treadmills. The displacement parameters of small treadmills for home use or fitness are not obvious, and it is easy to cause acceleration and deceleration shocks, so this method is not suitable for use
