Ultra-low power consumption exercise heart rate detection wireless module

Abstract

The invention discloses an ultra-low power consumption exercise heart rate detection wireless module, comprising a LED opto-sensor, a signal processing unit, a motion state monitoring unit, a microprocessing unit, a data memory cell, a bluetooth communication unit, and an output unit. The LED opto-sensor converts received light intensity variation to analog signals, and the signal processing unit performs preliminary noise reduction processing on the analog signals, and compensates signals which are damped through blood capillaries, and converts the signals into digital signals and transmits the signals into the microprocessing unit. The motion state monitoring unit acquires each item of motion data of a user, analyzes and determines the motion state of the user, and transmits the data to the microprocessing unit. The microprocessing unit makes heart rate detection data in different motion states more accurate through an advanced algorithm which is developed independently, cooperated with the motion state data sent by the motion state monitoring unit. The data is output through the bluetooth communication unit and the output unit, and the data is stored in the data memory cell.

Description

technical field [0001] The invention relates to the field of wearable exercise heart rate detection equipment, in particular to a wireless module for ultra-low power consumption exercise heart rate detection. Background technique [0002] Heart rate (HR) refers to the number of heart beats per unit time. It can be used as an indicator and basis for evaluating whether the exercise load is appropriate or not, as well as the functional state of the heart, and can also be used to judge whether the body has excessive fatigue and evaluate An indicator of exercise level. The measurement of heart rate is very important in sports training. Using heart rate monitoring during exercise can provide quantitative exercise results to reflect physical information during exercise, help enhance cardiopulmonary function, reduce muscle strain and soreness, and enable internal exercise Maximize the effect, prevent excessive exercise from causing physical injury and insufficient exercise, and imp...
