Real-time dynamic heart rate monitoring device and monitoring method

Abstract

The invention discloses a real-time dynamic heart rate monitoring device and monitoring method. The device comprises a baseline drift removal module, a band-pass filter module, a frequency domain analysis module and a heart rate frequency point selection module, wherein the baseline drift removal module is used for removing an interference signal of causing drift of the baseline of a pulse wave signal; the band-pass filter module is used for removing a noise signal out of a heart rate frequency band when obtaining a frequency signal component belonging to the heart rate frequency band; the frequency domain analysis module is used for obtaining a signal frequency spectrum of the pulse wave signal in a specific frequency band interval set in advance; the heart rate frequency point selection module is used for obtaining the frequency point corresponding to the heart rate and outputting the frequency point. The influences of human motion and muscle motion on heart rate analysis are eliminated; the hardware cost is reduced; the concerned frequency band interval can be flexibly selected; the frequency domain accuracy of the signal is improved only within the concerned frequency band; excessive computing and storage overheads are avoided.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a real-time dynamic heart rate monitoring device and a monitoring method. Background technique [0002] With the application and development of mobile Internet technology in the medical and health field, a large number of different forms of smart watches, smart bracelets, and smart wristbands have appeared on the market, capable of measuring heart rate, blood pressure, blood oxygen concentration, respiratory rate, etc. Parameters of wearable mobile health products. Heart rate is defined as the number of heartbeats per minute of the human body, and is an important medical routine physiological parameter for evaluating the health status of a person. Heart rate monitoring is of great significance for disease risk early warning, disease diagnosis, and annual routine physical examination. In particular, sports such as fitness activities and outdoor running have extensive application requi...
