Abstract

We performed the development and performance evaluation of reflective type heart rate measurement system for PAPS. We used chip LED and chip photo TR. for low power driving. The measured PPG signal is preprocessed using high pass filter and low pass filter, and the preprocessed signal is displayed by LabVIEW. Also LabVIEW include the algorithm that extract effective signal and calculate the heart rate. We made sure that it will be able to apply to measurement equipment with high accuracy and repetition from exercising subject using this system and algorithm.

PAPS(학생건강체력평가시스템, Physical Activity Promotion System)를 위한 반사형 맥박수 측정 장치를 개발 하고 성능평가를 수행하였다. 본 연구를 위해 제작된 센서 모듈은 저전력 구동을 위해 chip LED 및 photo TR.를 이용하여 맥파를 측정하였다. 측정된 맥파신호는 HPF, LPF와 OP Amp.를 이용하여 신호를 전처리하였으며, 전처리한 맥파신호는 LabVIEW로 디스플레이하였다. 또 LabVIEW는 원신호를 받아들여 유효신호를 추출하고, 맥박을 계산하기 위한 알고리즘을 포함한다. 이러한 시스템과 알고리즘을 이용하여 운동상태의 피실험자를 대상으로 높은 정확도와 반복성을 갖는 측정 기구로의 적용이 가능함을 확인하였다.
