Portable motion monitoring and detecting equipment and motion monitoring and detecting method

Abstract

The invention belongs to the field of human body motion sensing and monitoring, and particularly relates to portable motion monitoring and detecting equipment and a motion monitoring and detecting method. The motion monitoring and detecting method includes: selecting two red rays or infrared rays different in wavelength as incident rays, and enabling the incident rays to be vertically irradiated into fingers, wherein one of the incident rays is an infrared ray of 805nm in wavelength; adopting a reflective mode to measure pulse waves and blood oxygen concentration; calculating to acquire arterial blood oxygen saturation by respectively measuring IAC and IDC of reflection light signals of the red rays or the infrared rays according to a formula. Compared with transmission-type measuring methods, the motion monitoring and detecting method has the advantages that baseline drift caused by color scattering disturbance and motion disturbance of light is reduced, and accuracy and practicability are greatly improved when compared with those of conventional transmission-type pulse measuring.

AI Technical Summary

Problems solved by technology

[0004] Traditional transmissive pulse measurement is based on the principle of red light and infrared light transmission. Usually, pulse wave measurement and blood oxygen concentration measurement are realized by collecting red light and infrared light transmission photoplethysmogram signals from fingertips or ears; There will be a large motion interference with the measurement position of the ear tip, and a large baseline drift will occur, resulting in a large distortion of the photoplethysmography signal, and the pulse wave and blood oxygen saturation cannot be measured
