Human body movement measuring device, method and system

Abstract

The invention discloses a human body movement measuring device, comprising a body, a human body impedance measuring unit, and a movement analysis unit. The body is used for fixing the units herein andbearing a human body. The human body impedance measuring unit is used for measuring biological impedance of the human body. The movement analysis unit is used for carrying out statistical analysis onthe human movement according to a waveform of the biological impedance of the human body. The invention also discloses a human body movement measuring method based on the human body movement measuring device; the human body movement measuring method statistically analyzes human body movement via biological impedance wave of the human body. The invention additionally discloses a human body movement measuring system based on the human body movement measuring device; the human body movement measuring system comprises at least two human body movement measuring devices, a remote server, a statistical unit and a display 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...

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
