| Abstract: | The pronouncing instrument for examining heart rate(PIEHR) can collect the finger artery wave signal through the infrared photoelectrical sensor.Then,the instrument magnifies and plasticizes the signal which is sent to the Single Chip Microprocessor(SCM) for calculation through the frequency division.Afterwards,the signal is changed to the one-minute heart rate with the result being shown by LCD.Meanwhile,PIEHR has pronouncing function for broadcasting heart rate and alarming function. |
