Disclosed are a method and a system (20) for obtaining a physiological signal period. The method comprises the following steps: comparing a received physiological signal value with a temporary storage value and reserving one of the two values; judging the physiological signal value of which the hold time reaches a set time to be an extreme value, restarting the circulation and judging the next extreme value (S10); and obtaining a physiological signal period (S11) by calculating the time value between one extreme value and the next extreme value. The physiological signal period can be obtained by the method through the extreme value recognition algorithm, the method has the advantages of being simple, fast, and having high efficiency and reliability, etc.; and the requirements of amplification, filtration and analog-digital conversion of the physiological signal are low, the data processing is relatively easy, and therefore, the hardware spending can be greatly reduced. |
