Embodiment
The utility model is illustrated in more detail below in conjunction with accompanying drawing.
Referring to Fig. 3, in an embodiment of the utility model detection means, light is provided with simultaneously on detection means
Signal detection module and electrical signal detection module.Be arranged on detection means 100 bottom surface center photoelectric sensor 101 be used for
Processor in detection means inputs detected optical signal.The convenient singlehanded measurement of optical signal detecting module, passes through what is detected
Optical signal is fluctuated to obtain the real-time heart rate data of wearer.The first electricity is also respectively provided with the bottom surface of detection means 100
Pole 102, second electrode 103, the side of detection means 100 or upper surface are provided with detecting electrode 104.Detecting electrode 102,
103 and 104 respectively as first via differential input signal, reference signal and the second road differential input signal and electrical signal detection mould
Potential difference detector connection in block, wrist surface electrical signal data is exported from potential difference detector to processor.Electric signal is examined
Surveying module needs to work during three electrode 104 of extremity, it is usually the case that being measured for both hands, belongs to flip-over type inspection
Survey pattern.When suspecting the Real-time Monitoring Data inaccuracy of optical signal detecting module, or the inspection that optical signal detecting module provides
Survey data and show body when there is certain disease condition, or when user feels uncomfortable, electric signal inspection can be started
Module measurement body electrical signals are surveyed, so as to verify data or examine health.In addition, electric pole type metering system can also be caught
The abnormal electrocardiogram diagram data of burst is grasped, and PPG metering systems can only provide heart rate data.Thus, electric pole type metering system
Introduce, be the useful supplement of PPG metering systems, improve the rich of measurement data.It is pointed out that first electrode 102
Not necessarily it is generally disposed at second electrode 103 with photoelectric sensor 101 on straight line.In general, photoelectric sensor
101 are generally disposed at the bottom surface center of detection means 100, and the position of first electrode 102 and second electrode 103 on bottom surface is use up
Amount away from, can be set such as Fig. 3, can also be separately positioned on detection means 100 the relative folding corner region in bottom surface or
Other positions.3rd electrode 104 is arranged on the side or upper surface of detection means 100, with first electrode 102, second electrode 103
And the set location of photoelectric sensor 101 is unrelated.
When the detection means bottom surface on wearable device and skin attachement be not tight, easily there is the situation of light leak, cause
Photoelectric sensor can't detect useful optical signal.In order to overcome this problem, the utility model, which additionally provides, sets two light
The embodiment of electric transducer, it include scattering device the bottom surface of detection means two photoelectric sensors, respectively with two
Two AFE(analog front end)s and hub corresponding to one of photoelectric sensor, photoelectric sensor pass sequentially through respective AFE(analog front end) with
And hub is connected with processor.As shown in figure 4, two photoelectric sensors of scattering device on the bottom surface of detection means 100
101.So, when being tilted in the side of bottom surface, because there is provided two photoelectric sensors, the contact of at least one photoelectric sensor
Good probability is much larger than the situation that a photoelectric sensor is only set in bottom surface center.
In addition, inventor by studying repeatedly, it is found that at wearer's wrist activity (for example, palming, lift wrist or vertical wrist)
When, detected in the wrist strap direction of wearable device (in Fig. 4 X-direction, namely described above " second direction ") most probable
The situation that the bottom surface of equipment tilts.Thus, in preferred embodiment of the present utility model, two photoelectric sensors 101 are set
Put in X-direction.The benefit so set is that have tilting in X-direction in the bottom surface of detection means 100 and produce light leak from Y-direction
When, a photoelectric sensor 101 of tilting is difficult to provide useful detection data, but another is just with skin contact tighter
It is close, can effectively it work.Photoelectric sensor 101 is arranged such, on the one hand can reduce the wearing requirement to wearer, such as be not required to
Want the bottom surface of detection means to be brought into close contact skin completely, improve the comfortableness of wearing；On the other hand, due to even being filled in detection
In the case of putting 100 bottom surface side tilting, detection means 100 remains able to normal work, On-line sampling system, so as to significantly
Improve the accuracy of detection data.
In order to be further ensured that the accuracy of detection data, electrical signal detection is additionally provided with Fig. 4 detection means 100
Module, so that the detection data to optical signal module are verified.Y-direction in the bottom surface of detection means 100 is respectively arranged with

102nd, 103 and 104 examined respectively as first via differential input signal, reference signal and the second road differential input signal and electric signal
The potential difference detector connection surveyed in module, detection data are exported from potential difference detector to processor.As described above, suspecting
During the Real-time Monitoring Data inaccuracy of optical signal detecting module, the detection data that optical signal detecting module provides show that body occurs
During certain disease condition, or when user feels uncomfortable, electrical signal detection module measurement body telecommunication can be started
Number, so as to verify data or examine health.
The bottom surface Top electrode of the utility model detection means and the preferred scheme of photoelectric detector setting are provided in Fig. 4,
But it will be apparent that first electrode 102 and second electrode 103 are not necessarily set in the Y direction.As described above, they
Typically it is located remotely from each other on bottom surface.Similarly, the 3rd electrode 104 is arranged on the side or upper surface of detection means 100, with
The set location of first electrode 102, second electrode 103 and photoelectric sensor 101 is unrelated.
Because the colour of skin of wearer is different, the absorption to light is different with reflectivity.So for PPG metering systems,
Allow photoelectric sensor to provide the transmitting light selection of multi-wavelength to user, be beneficial to improve the accuracy of detection.Cause
This, in preferred embodiments, photoelectric sensor should include a photodiode and at least two and send out different colours light
Light emitting diode, such as green light and rubescent optical diode.It is highly preferred that rubescent outer optical diode can also be included again.
The bottom shape of the utility model detection means is not limited to square shown in accompanying drawing, can also be circle, oval
Shape, etc..Similarly, the shape of the electrode and photoelectric sensor that are arranged on detection means bottom surface can be any suitable shape
Shape, such as circular, ellipse, square, polygon etc., and the shape of each electrode and each photoelectric sensor can be with
It is identical, can also be different, those skilled in the art can voluntarily adjust as needed.
