Problems solved by technology

[0004] 1. The collected data is unstable: during the data collection period, it is easily affected by factors such as mechanical shaking, emotional fluctuations of the testee, and physical activities, resulting in data deviation, resulting in inaccurate HRV analysis
[0005] 2. HRV analysis is inaccurate due to imprecise and inaccurate algorithms used in HRV analysis

Embodiment Construction

[0036] The present invention is further described in conjunction with the following examples.

[0037] A kind of heart rate analyzer of this embodiment, its processor executes the following steps when acquiring heart rate data, can refer to figure 1 :

[0038] Step 1: Obtain the RRI sequence (abbreviation of R-R interval, meaning RR interval) according to the data output by the PPG heart rate sensor.

[0039] Step 2: Perform detrend analysis on the RRI sequence, because the sensor will also input abnormal PPG data into the heart rate analyzer in the early stage, resulting in abnormal analysis results, and detrend analysis can eliminate abnormal sequences.

[0040] Among them, the detrending judgment is based on the following formula to form a log-log coordinate:

[0041]

[0042]

[0043] In the scatter plot in log-log coordinates (ln(n), ln(F(n))), the data points are fitted by the least squares method to obtain a curve, and the slope of the straight line part of the ...

Abstract

The invention relates to a computer readable storage medium and a heart rate analyzer using the same and belongs to the heart rate sensing technological field. The heart rate data output process of the heart rate analyzer includes the following steps that: step 1, an RRI sequence is obtained according to data outputted by a PPG heart rate sensor; step 2, de-trending analysis is performed on the RRI sequence; step 3, re-sampling is carried out, so that a uniformly-distributed RRI sequence can be obtained; step 4, Hamming windowing is carried out to divide the uniformly-distributed RRI sequenceinto small overlapped segments; step 5, power spectrum estimation is performed on each sequence segment; step 6, the average values of the power spectrum estimates of each frequency band are calculated; and step 7, integral processing is performed on the average values of the power spectrum estimates of each frequency band, so that the power values of an ultra-low frequency band (ULF), a very-lowfrequency band (VLF), a low frequency band (LF), and a high frequency band (HF) are obtained, and the power values of the four frequency bands are added, so that signal total power TP can be obtained.With a simpler method adopted, the heart rate analyzer can process acquired heart rate data into heart rate data with higher accuracy which can be used by a user.

Description

technical field [0001] The invention relates to the technical field of heart rate sensing, in particular to a computer-readable storage medium and a heart rate analyzer using the medium. Background technique [0002] With the gradual increase in the popularity of smart wearable devices and the increasing awareness of users on products, the global wearable device market is developing rapidly. At present, smart wearable products on the market are changing with each passing day, and the frequency of replacement is relatively high, which reflects that people have a relatively strong demand for smart wearables, especially in the field of health assessment. Recently, it has been discovered that the measurement and evaluation of heart rate variability has great reference value and significance for analysis and evaluation to health. Therefore, smart wearable products with heart rate variability detection function have huge market value, and products with PPG heart rate sensors can ...
