Research on Real-time Heart Rate Measurement System for ECG Monitor Based on IPPG
In order to better address the issues of poor performance and insufficient data extraction ability of electrocardiogram(ECG)monitors in real-time heart rate measurement,a new ECG monitoring system based on photoelectric capacitance pulse plot technology is proposed.The system efficiently processes the data of the ECG monitor using the photoelectric capacitance pulse plot technology,and uses an improved wavelet transform method to denoise the data.After experimental testing,the system significantly reduces the amplitude of changes in the ECG waveform after the data denoising processing,and the overall range of changes is 0.4 mV lower than that before denoising;The obtained heart rate data is closer to that of the original heart rate change image,with a maxi-mum change of only 2 bpm;The signal-to-noise ratio of the research method reaches 16.057 8,with a root mean square error of only 0.019 5,which is 0.022 9 lower than that of the average filter method.This system has a better data processing performance in real-time measurement of human heart rate,which can effectively improve the accuracy and real-time performance of heart rate measure-ment,providing an important reference and application value for the development of heart rate real-time monitoring technology.
