Device, method and system for measuring human body motion

Abstract

The invention discloses a human body motion measurement device, which includes a body, a human body impedance measurement unit, and a motion analysis unit. The main body is used for fixing each unit of the device and supporting the human body; the human body impedance measurement unit is used for measuring the bioelectrical impedance of the human body; the motion analysis unit performs statistics on human body movement according to the waveform of the human body’s bioelectrical impedance analyze. The invention also discloses a method for measuring human body movement based on the above-mentioned human body movement measuring device, that is, using human body bioelectrical impedance waves to statistically analyze human body movement. The present invention also discloses a human body motion measurement system based on the above-mentioned human body motion measurement device, which includes at least two of the above-mentioned human body motion measurement devices, a remote server, a statistical unit and a presentation unit.

Description

technical field [0001] The invention belongs to the field of motion measuring devices. Background technique [0002] With the rise of wearable devices, when people are exercising, such as running and walking, they are used to counting the distance they run and the number of steps they walk through their mobile phones, wristbands or smart watches. However, many other popular indoor sports, such as push-ups, squats, planks, etc., do not have very convenient tools to assist in statistics. For example, for push-ups, the existing technology solves the problem of automatic counting of push-ups from several aspects, including [0003] 1) Pressure type, such as patents (applications) CN201010146271.X, CN201510502275.X and CN201510579134.8, etc., realize the recognition of push-up actions by installing pressure sensors on the push-up equipment, and the purpose is relatively single. [0004] 2) The photoelectric type, including the infrared directing type and the reflective type, us...

AI Technical Summary

Problems solved by technology

This method is easier to cheat by simulating human movement through non-human occluders. At the same time, infrared reflection has requirements for the flatness and color of the reflective surface. Clothes worn by the human body are easy to cause misjudgment due to different colors and folds.

[0005] 3) Ranging method, including ultrasonic ranging, etc. For example, the principle of the scheme recorded in patent (application) CN200920280144.1 and CN201501470605.1 is to realize the counting by measuring the periodic change of the distance between the body and the ground during the push-up exercise by the ranging module, Its disadvantages are similar to the above-mentioned schemes. On the one hand, it is easy to be misjudged by simulating human body movement due to non-human occlusions; on the other hand, ultrasonic waves have requirements for the flatness of the reflecting surface, and the wrinkles of clothing will cause ranging failure and thus recognition errors

The emergence of step counting devices such as wristbands has promoted everyone's enthusiasm and planning for sports, but for some common indoor sports and family sports, such as push-ups, squats, planks, etc., there is still a lack of effective, simple structure, and easy-to-use recording, management and statistical analysis tools
