도 4에 나타낸바와 같이 상기 심박 측정부는 운전자의 심박(맥박) 수를 검찰하여 검출된 심박수에 대응되는 심박신호를 판단부(300)에 전송한다. 호흡 및 복부 팽창량 측정부는 복부라인에 설치된 압전센서가 운전자의 호흡에 따른 복부의 팽창 및 수축량을 실시간으로 측정하여 측정된 신호를 판단부(300)에 전송한다.(S100)As shown in FIG. 4 , the heart rate measuring unit detects the number of heartbeats (pulses) of the driver and transmits a heartbeat signal corresponding to the detected heart rate to the determination unit 300 . The respiration and abdominal expansion measurement unit transmits the measured signal to the determination unit 300 by a piezoelectric sensor installed in the abdominal line measuring the amount of expansion and contraction of the abdomen according to the driver's breathing in real time. (S100)

상기 판단부(300)는 기존 어플로부터 운전자의 기존 호흡량 및 호흡률, 심박수를 기준신호로 수집한다.(S200)The determination unit 300 collects the driver's existing respiration rate, respiration rate, and heart rate from the existing application as reference signals. (S200)

수집한 기준신호를 디저털 신호로 변환하고 상기 기준신호에 따른 기준 호흡량 및 호흡률을 산출한다.(S300)The collected reference signal is converted into a digital signal and the reference respiration rate and respiration rate are calculated according to the reference signal. (S300)

판단부(300)가 상기 측정신호를 디지털 신호로 변환하고(S400) 상기 측정신호에 따른 현재 심박수, 호흡량 및 호흡률이 상기 기준 심박수, 호흡량 또는 호흡률에 대비하여 일정 범위를 넘는 변화가 발생하는 경우(S500)The determination unit 300 converts the measurement signal into a digital signal (S400), and the current heart rate, respiration rate and respiration rate according to the measurement signal change beyond a certain range in comparison to the reference heart rate, respiration rate or respiration rate. S500)
