ECG measurement-based heart rate earphone, heart rate test method and device

Abstract

The invention provides an ECG measurement-based heart rate earphone, a heart rate test method and a device, and relates to the technical field of earphones. The earphone structurally comprises an earphone body. The earphone body is provided with a left-ear electrode and a right-ear electrode. The earphone body is also provided with an acceleration sensor, a data processor and a communication module. The acceleration sensor is matched with the left-ear electrode and the right-ear electrode to collect the acceleration and the heart rate of a rider during riding. A corresponding table between a riding speed X, and the difference between a heart rate curve tested by three electrodes at the riding speed X, and a heart rate curve tested by two electrodes at the riding speed X, is established. After that, the data processor is placed into the corresponding table for query purpose. As a result, heart rate data can be tested by utilizing two electrodes. In combination with the actual riding speed tested by the acceleration sensor, heart rate data tested by utilizing three electrodes can be obtained through the inverse method. The ECG measurement-based heart rate earphone can utilize only two electrodes. Compare with existing heart rate earphone based on three electrodes, the above heart rate earphone is simple in structure and convenient to use. The heart rate test method is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a heart rate earphone based on ECG measurement and a heart rate testing method thereof. Background technique [0002] At present, most of the heart rate earphones on the market adopt the PPG measurement method. PPG is measured by measuring the change of blood oxygen content. If the human body performs intense anaerobic exercise, the blood oxygen content will change nonlinearly. The test results are different from the actual ones. The error is large. [0003] At present, the general method of measuring heart rate is ECG, which is called electrocardiogram, that is, electrocardiogram. The so-called ECG (electrocardiogram) means that in each cardiac cycle, the heart is successively excited by the pacemaker, atrium, and ventricle. Graphics (ECG for short). The electrocardiogram is an objective indicator of the occurrence, propagation and recovery process of cardiac excitement. ...

Problems solved by technology

[0005] However, when the heart rate test method using three electrodes is applied to the earphone, one of the three electrodes needs to be placed on the arm, which is not convenient to use
