Embodiment Construction

[0026] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0027] see figure 1 As shown, the present invention provides a method for improving the accuracy of heart rate detection, specifically:

[0028] Using the DT algorithm for ECG signal analysis, the specific steps are as follows: first, preprocess the signal, including: 8-16Hz band-pass filter to suppress noise and baseline drift; square after differentiation, obtain slope information and enhance QRS wave; and then perform 100M The ECC data in the mobile sensor window is integrated to obtain the R wave slope value, and then the detected peak position and maximum slope value information are extracted. According to the QRS wave detection rule, the T ...

Abstract

The invention aims to solve the technical problems of the existing products and provides a method capable of increasing the heart rate detection accuracy, and the method can realize accurate detection to heart rate data by wearable equipment. Meanwhile, the invention provides a system capable of accurately detecting the heart rate accuracy. The two inventions provide a further guarantee for the life safety of old people.

Description

technical field [0001] The invention relates to a method and system for improving the accuracy of heart rate detection, belonging to the field of smart sensors and wearable devices. Background technique [0002] There are about 1,480 sudden cardiac deaths in China every day, which is equivalent to the number of people killed by 7 MH370 planes. Sudden cardiac death refers to sudden death caused by a heart attack. Before sudden death, there may not be any manifestation of heart disease, and the time of occurrence cannot be predicted. The direct cause of sudden death is that the cardiovascular system cannot maintain blood supply to the brain due to dysfunction or loss. resulting in loss of consciousness. Almost everyone will experience arrhythmia in their lifetime. When there is a disease in the heart, the arrhythmia will be more frequent and serious, and even life-threatening. Due to the lack of effective prevention and monitoring means, the proportion of prevention and resc...
