In the biosignal receiving step, an ECG signal, a PPG signal, a body temperature signal, and an acceleration signal are received from the A / D converter 390 and stored in a buffer (S810).

In the biosignal size comparison step, it is determined whether the biosignal is a size that can be arithmetic processed by the data controller 400, and it is determined whether the biosignal is small by comparing the received biosignal with a processing reference minimum threshold value; S820), if the processing threshold is smaller than the minimum threshold, the amplification rate of the detected biosignal is increased (S830), and the flow returns to the biosignal size comparison step (S820). Increasing the amplification rate of the biosignal may increase the amplification rate in the biosignal preprocessor 300 or the A / D converter 390 or receive the biosignal data with a higher amplification rate in the biosignal receiving step.

In the heart rate measurement step, if the biosignal received in the biosignal size comparison step (S820) is greater than or equal to the processing threshold minimum threshold, a biometric parameter including a heart rate is calculated by processing an ECG signal or a PPG signal among the received biosignals. Are detected (S840).

As the exercise degree evaluation step, the exercise degree evaluation parameter is obtained by performing arithmetic processing from biometric parameters including the heart rate detected in the heart rate measurement step S840 (S845). In the exercise evaluation step, the exercise evaluation parameter may be detected using parameters such as heart rate and activity.

In the determination of whether the exercise degree is normal, it is determined whether or not the exercise degree evaluation parameter obtained in the exercise degree evaluation step is out of the previously stored exercise standard value (S850), and in the exercise degree determination whether the exercise level is normal (S850). If so, the alarm control signal or the display control signal is transmitted to the alarm unit 420 or the status display unit 430 of the biofeedback unit 410 according to the degree of danger (S860).

In the data storage method selection step, it is determined whether the measurement data is set to be stored in the computer (S860). If the measurement data is not set to be stored in the computer, the measurement data is stored in the data storage unit 440 ( S870).

As a data storage step in the computer, if it is set to store the measurement data in the computer in the data storage method selection step (S870), the measurement data is stored in the computer using wired or wireless communication (S880).

In the step of determining whether the measurement is completed, the measurement completion flag of the data control unit is set by the user setting the measurement completion button (in some cases, as the user's exercise device operation is completed), and if the measurement completion flag is set, If not, otherwise, return to the biosignal receiving step (S810).
