Problems solved by technology

However, the instantaneous heart rate is obtained from adjacent peaks, and if a signal is discarded, two instantaneous heart rates will be missing, which will cause a delay in the average heart rate

Abstract

A signal processing method, an apparatus and a non-transitory computer readable storage medium are provided. A plurality of segment signals are taken out based on a time series from a physiological signal, and each segment signal is determined as a desirable signal or an undesirable signal. In response to the ith segment signal is determined as the undesirable signal, under the condition of determining that both of the (i-2)th segment signal and the (i+2)th segment signal are the desirable signals, the ith segment signal is reserved. A plurality of instant heart rates are calculated based on the desirable signals and the reserved undesirable signals.

Description

technical field [0001] The present invention relates to a signal processing method, device and non-transitory computer-readable storage medium, and in particular to a signal processing method, device and non-transitory computer-readable storage medium for calculating heart rate. Background technique [0002] In recent years, with the public's emphasis on health, various monitoring devices that can monitor heartbeats have begun to appear on the market. When the wearer is in a stable state, the monitoring device can obtain the best physiological signal. When the wearer makes sudden movements (such as turning the head, nodding, getting up, etc.), the monitoring device will generate noise and affect the accuracy. In the past, the acceleration signal of the accelerometer (Accelerometer) was used to determine whether the wearer has moved. When the wearer is still, the peak value can be calculated smoothly, then the instantaneous heart rate can be calculated from the time differe...
