103, vasoreflex signal is determined from the multiple scanning reflection signal.
Wherein, the vasoreflex signal is the vascular scan signal in the signal for being irradiated to blood vessel back reflection.
After abovementioned steps 102 obtain multiple scanning reflection signals, multilayer is had based on tissue, because
This, after vascular scan signal is irradiated to human body, based on different angles, and not all scanning signal is all to be irradiated to people
Body blood vessel back reflection, it is to be irradiated to epidermis to be reflected that some, which may be vascular scan signal, in multiple scanning reflection signals
, or it is irradiated to what fat deposit was reflected, it therefore, can after obtaining multiple scanning reflection signals in abovementioned steps 102
To judge multiple scanning reflection signal according to the method in this step, the reflection letter for being irradiated to blood vessel is therefrom determined
Number, i.e., the described vasoreflex signal.
When the optical signal received is converted into electric signal, since blood vessel changes the absorption of light and its hetero-organization is to light
Absorption be basically unchanged, therefore the signal obtained in measurement process can be divided into direct current DC signal with exchange AC signal, and
AC signal therein, the characteristics of blood flow can be reflected.Therefore, which is blood in judging multiple scanning reflection signals
When pipe reflects signal, it can be determined based on the ratio of AC and DC in collected signal.

The mode of scanning signal.It therefore, can be according to reality in this step for the emission process of selected vascular scan signal
Situation chooses corresponding radiation pattern, does not do specific restriction herein.
As a result, by the transmitter of control predetermined quantity, multiple angles are chosen respectively to human-body emitting vascular scan signal,
It may insure the vascular scan letter that multi-angle is able to carry out when being provided that the transmitter of variable-angle in intelligent wearable device
Number emission function, or be provided with the transmitters of multiple fixed angles by controlling, successively believe to human-body emitting vascular scan
Number, then it can ensure when being provided that the transmitter of multiple fixed angles in intelligent wearable device, carry out multi-angle blood vessel and sweep
Retouch the emission function of signal.It can ensure that heart rate test method described in the embodiment of the present invention can be applied to different hardware in this way
In the wearable device of setting, there is well adapting to property.

It is reflected after being irradiated to blood vessel, it may be possible to be irradiated to fat deposit or epidermis reflected, for such signal, actual
In measurement process, too big meaning is had no, therefore, in embodiments of the present invention, it is also necessary to anti-to current acquired multiple scannings
It penetrates signal to be filtered and screen, therefrom determination is irradiated to the reflected signal of blood vessel, i.e. blood vessel described in the embodiment of the present invention is anti-
Penetrate signal.In addition, the electric signal converted after receipt based on reflection signal includes AC and DC two in specific operating process
Part, and the part DC can be understood as the ambient noise of human body reflection, AC is then variation actually significant to heart rate detection
Signal.It, can be based on the ratio between AC and DC when therefore, for carrying out judging which is vasoreflex signal in this step
It is determined, i.e. signal-to-noise ratio, wherein ratio is bigger, illustrates that actually active signal is more in the signal, illustrates that it is to be irradiated to blood
Reflection signal after pipe.Therefore, specifically, this step can be with are as follows: anti-according to scanning each in the multiple scanning reflection signal
The corresponding signal-to-noise ratio of signal is penetrated, determines vasoreflex signal described in the multiple scanning reflection signal.
Specifically, this step may include: to calculate each scanning reflection firstly, according to the multiple scanning reflection signal
The signal-to-noise ratio of signal.Then, according to the corresponding signal-to-noise ratio of each scanning reflection signal, the maximum scanning reflection letter of signal-to-noise ratio is determined
Number.Finally, the maximum scanning reflection signal of signal-to-noise ratio is determined as the vasoreflex signal.
As a result, by according to the multiple scanning reflection signal, calculating the signal-to-noise ratio of each scanning reflection signal, and according to
The corresponding signal-to-noise ratio of each scanning reflection signal, determines the maximum scanning reflection signal of signal-to-noise ratio, then that signal-to-noise ratio is maximum
Scanning reflection signal is determined as the vasoreflex signal, can determine multiple scanning reflection signals with the actual value of signal-to-noise ratio
In vasoreflex signal, then ensure vasoreflex signal determine accuracy, to improve heart rate measurement on the whole
As a result accuracy.
204, according to the vasoreflex signal, human heart rate is measured.
In order to ensure the accuracy of heart rate measurement, when abovementioned steps have determined the vasoreflex signal in multiple scanning signals
Afterwards, we can determine which the vascular scan signal before reflection is according to the reflection signal, then can be according to the blood vessel
Scanning signal determines that sequence occasionally needs signal projector to be used and its angle in actual monitoring process, and then according to the transmitter
And angle continues to emit vascular scan signal and carries out corresponding heart rate measurement.Based on this, this step be can specifically include: first
First, according to the vasoreflex signal, corresponding vascular scan signal is determined.Then, it is determined according to the vascular scan signal
