The overall schematic of the wearable detection heart rate device that Fig. 2 provides for the embodiment of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Be described in detail below in conjunction with the realization of concrete accompanying drawing to the present embodiment.
As shown in Figure 1, the invention provides Wearable and detect heart rate device, comprise the matrix 1 that can directly be worn on human body, matrix 1 is provided with fixture, matrix 1 can be fixed on human body, and fixing rear matrix 1 is close on human skin.Be close to human body place at matrix 1 to be provided with for accepting light and detecting the sensor 11 of light intensity change and the illuminator 12 for releasing detection light, the matrix 1 inside signal of telecommunication be provided with for being accepted by sensor 11 is transformed into the center module of heart rate data.
Matrix 1 can directly wear by user, sensor 11 and illuminator 12 are close to skin, illuminator 12 discharges detection light, transdermal and each tissue, when heart contraction and diastole, subcutaneous blood oxygen concentration is mechanical periodicity, absorbs light intensity different, passback sensor 11 receives the detection light intensity reflected and also changes in periodization, the signal of telecommunication of exporting change is to center module, and center module can timing, then calculates the current heart rate of user according to the signal of telecommunication of sensor 11.Owing to being Wearable, do not need by special armarium, be close on skin simultaneously and can receive detection signal at any time, allow user can the heart rate of monitoring oneself at any time with oneself, be particularly useful for the user that some special diseases need timing monitoring heart rate.
Illuminator 12 is at least three LED 121, and adopt the design of four LED 121 in the present embodiment, be evenly arranged around sensor 11 surrounding, the distance between each LED 121 center and the center of sensor 11 is between 2mm to 7mm.
PPG signal relies on the reflection detecting light to obtain, and due to the diversity of partes corporis humani position vascular tissue distribution, PPG signal intensity is also different.Even if at same skin place, the signal that surrounding subcutaneous tissue difference obtains also has difference.PPG signal itself is very easy to the impact being subject to motion artifacts simultaneously, and especially in portable equipment, how effectively improving signal to noise ratio, is technological difficulties.
Find through long-term research and experiment, take at least three light sources to do detection light source, effectively can improve the PPG signal intensity of acquisition.The mode adopted in the present embodiment be four LED 121 around setting, greatly can improve the PPG signal intensity of acquisition.And the distance between LED 121 and sensor 11 is arranged, also there is larger impact to the levels of precision of the signal gathered, if hypotelorism, or excessively far away, all make the PPG signal gets too small obtained, thus affect accuracy of detection; After test of many times research, in the present embodiment, the distance between the center of each LED 121 and the center of sensor 11 is remained between 2mm to 7mm, can ensure that the intensity of variation and the illumination of sampling is positioned at the scope of an appropriate balance.
