Wrist-worn heart rate monitoring device and heart rate monitoring control method

Abstract

The present invention proposes a wrist-worn heart rate monitoring device and a heart rate monitoring control method. The device includes a photoelectric heart rate monitoring unit, a six-axis acceleration sensor, a processing unit, a skin electricity detection unit, and a reminder unit; the skin electricity detection unit includes two or more than two electrode pairs for electrodermal detection and electrodermal detection sensors; the electrode pairs are arranged on the skin bonding surface of the device, and the two electrodes of each electrode pair are intersected to perform diagonal cross detection; the processing unit is based on the electrode Detect whether the device is worn correctly according to the preset conditions for the collected electrical skin signals, and send a reminder command; the reminder unit receives the command and reminds; the processing unit analyzes the device according to the preset conditions based on the spatial motion coordinate parameters collected by the six-axis acceleration sensor state of motion. Through the present invention, it is possible to detect in time the poor fit of the wristband with the skin when the wristband is worn and to remind it, which indirectly avoids the problem of inaccurate data collection caused by the device being displaced or not being worn securely during exercise.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a wrist-worn heart rate monitoring device and a heart rate monitoring and control method. Background technique [0002] With the improvement of people's living standards and the acceleration of the pace of life and work, people pay more and more attention to their own health, and the demand for monitoring their own body parameters is also increasing. Heart rate is an important body parameter, which can be used as an assessment Whether the exercise load is appropriate or not can also be used as an indicator and basis for the health of the heart function. [0003] At present, the more convenient heart rate acquisition device is the heart rate acquisition bracelet. The photoelectric heart rate sensor installed in it is used for heart rate acquisition through the wrist when the user wears it. However, the collected data is noisy, and the collected data is only used for rough Knowing the g...
