Problems solved by technology

[0004] Although the above-mentioned invention patent adopts the denoising algorithm of the dual-channel signal, both channels are green light signals of a single light source, and the reference signal variables are insufficient, and the green light is easily absorbed by shallower dark skin and tattoos, making it difficult to reflect Changes in blood volume in the deep blood vessels of the skin, the measured data is inaccurate, and there will be large errors

Abstract

The invention discloses an array arrangement circuit for measuring the heart rate and blood oxygen. The circuit comprises a transmitting group, a receiving group and a sensor; the transmitting group,the receiving group and the sensor are arranged on the surface, making contact with a wrist, of a detection device; the transmitting group comprises four transmitting parts emitting different color light signals, and the transmitting parts are arranged in a rectangular array; the receiving group comprises six receiving parts receiving different color light signals, and the receiving parts are arranged in an annular array. Accordingly, by means of color light signals with different wavelengths, heart rate and blood oxygen measurement is conducted according to different measurement situations, and the whole measurement is higher in accuracy and better in stability.

Description

technical field [0001] The invention relates to the technical field of heart rate and blood oxygen measurement, in particular to an array arrangement circuit for measuring heart rate and blood oxygen. Background technique [0002] With the accelerated pace of work and life, heart rate and blood oxygen are important physiological indicators to measure human health. Therefore, real-time monitoring of health data such as heart rate and blood oxygen is becoming more and more important for people living in a fast-paced life. There are many types of products used to monitor heart rate and blood oxygen, but many of them have inaccurate detection: the heart rate algorithm of PPG based on green light to collect wrist photoplethysmography signals, the single-channel signal collection method is different in different skin colors And in the case of human sweating, because of the inaccurate measurement of different reflectance; measurement methods such as independent component analysis m...
