End time.
S33, by by the starting point of described start time and end time and described important plot time period and end
Point compares, and corrects the moment of described important plot time period beginning and end.
The described important plot time period is manually to demarcate in advance, and it determines have certain subjectivity.If
During Practical Calculation, find that the real-time heart rate of many users occurs the interval of fluctuation and the important plot preset
Time period deviation value is relatively big, then can be adjusted the beginning and end of important plot time period so that it is more
Add accurately.
Optionally, when correcting the moment of described important plot time period beginning and end, can be by judging
A number of user changes in heart rate situation before and after each important plot time period, if statistics obtains big portion
Demultiplexing family heart rate occurs the gap between gap and terminal between the starting point of fluctuation the least, and described big portion
There is rising of the average of the starting point of fluctuation and the average of terminal and described important plot time period in demultiplexing family heart rate
Point and terminal gap respectively is bigger, it is possible to the beginning and end of described important plot time period changed into respectively
There is average and the average of terminal of the starting point of fluctuation in described major part user's heart rate, in order to follow-up measurement and meter

Optionally, if trying to achieve S more than SmaxOr less than Smin, it is judged that S and SmaxOr S and SminBetween
Departure degree is the most sufficiently large, if sufficiently large, then illustrates that this heart rate measurement process goes wrong, and result is not
Accurately, it should not report this time calculated mark.
In other alternative-embodiments, it would however also be possible to employ scoring is calculated by other calculating formulas, such as,
According to above-mentioned computational methods, S is multiplied by again a regulation coefficient；Regulation coefficient is with the increasing of n Yu N difference
Add and increase；So when the user's average heart rate value recorded and standard value deviation are bigger, can expand further
This gap big, to fully demonstrate the intensity of variation of user's heart rate.
In an alternate embodiment of the invention, step S50, measure this user average heart rate value under tranquility,
Including:
S60, obtains after measurement instruction, the timing measure user's beats of starting from scratch.Described measurement instruction
Sent by user；For example, it is possible to increase the option of " measurement standard heart rate " in terminal, user is whole after pressing
Termination receives measurement instruction, points out user to keep tranquil by the mode such as word or voice, and terminal starts timing
And measure.
S61, if t recordsLess than the Second Threshold preset, from the beginning of t
Measure the average heart rate value of user in the second duration, as this user average heart rate value under tranquility.
Described T is default time interval, described B0For total beats of user, described B before t1For t-T
Total beats of user, described B before moment2For total beats of user before the t-2T moment.The meaning of this step
Justice is, the change comparing the user's average beats in adjacent two time intervals is the most sufficiently small, if foot
Enough little, illustrate that user has come into more tranquil state, calculate user in certain time from this moment on
Average heart rate can relatively accurately obtain this user average heart rate value under tranquility.
