In order to illustrate the technical solutions in the embodiments of the present disclosure or the existing arts more clearly, the drawings need to be used in the description of the embodiments or the existing arts will be briefly described in the following; it is obvious that the drawings described below are only related to some embodiments of the present disclosure, for one ordinary skilled person in the art, other drawings can be obtained according to these drawings.
Embodiments of the present disclosure provide an intelligent wearable device and a detection method of biometric information, which can simultaneously detect multiple types of biometric information and hence improve the integration of the intelligent wearable device and simplify the structure of the intelligent wearable device.
In order to illustrate the objectives, the technical solutions and advantages of the present disclosure more clearly, embodiments of the present disclosure will be described below in more details. It is obvious that the described embodiments are just a part but not all of the embodiments of the present disclosure. Based on the embodiments of the disclosure, other embodiments obtained from the present disclosure by those skilled in the art without making additional inventive work should be within the scope of the present disclosure.
As illustrated in
The biometric information of the human body may be detected by adoption of the technical solution of the embodiment, so that the health condition of the human body can be obtained. Moreover, the intelligent wearable device can simultaneously detect multiple types of biometric information. Since a same light source is adopted to provide detection light for the first photoelectric detection module and the second photoelectric detection module, the structure of the intelligent wearable device is simple and the cost of the intelligent wearable device is low.
In the embodiments of the present disclosure, a specific type of the intelligent wearable device is not limited, for instance, the intelligent wearable device may be an intelligent ring, an intelligent watch, an intelligent wristlet, etc. In one embodiment of the present disclosure, the intelligent wearable device is an intelligent wristlet and may be worn around a wrist of a human body. For instance, the intelligent wearable body is a wristlet body; the light source, the first photoelectric detection module and the second photoelectric detection module are disposed on an inner side of the wristlet body; the light source is arranged towards the first photoelectric detection module; and the second photoelectric detection module is disposed on a reflection path of light reflected by the wrist.
In the embodiments of the present disclosure, the biometric information determined by the transmitted light that passes through the human body is the first type of biometric information. For instance, the first type of biometric information may include venous information.
In the embodiments of the present disclosure, the biometric information determined by the reflected light that is reflected by the human body is the second type of biometric information. For instance, the second type of biometric information may be heart rate information, blood oxygen status information, etc.
Taking the intelligent wearable device to be an intelligent ring as an example, as illustrated in
A specific type of the light source 12 on the intelligent wearable device is not limited, as long as the light emitted by the light source can run through the human-body wearing part 100 and be reflected by the human-body wearing part 100. For instance, the light source 12 may adopt an LED source having the advantages of energy saving, high efficiency, no strobe and long service life. For instance, a near infrared light monochromatic LED source may be adopted, and near infrared light emitted by the light source has the wavelength of more than 0.4 μm and basically has no harm to the human body.
In the technical proposal as shown in
For instance, the principle for determining the venous information of the finger includes that: as hemachrome in blood has characteristic of absorbing near infrared light, the first photoelectric detection module may convert the received transmitted light into electric signals, and subsequently, a venous image of the finger is formed after data processing. The processing module may determine the venous information of the finger by adoption of processing means such as filtering, image binaryzation and thinning.
For instance, the principle for determining the heart rate information and the blood oxygen status information of the human body includes that: the second photoelectric detection module may convert the received reflected light into electric signals; when the heart rate of the human body changes, the frequency of the reflected light reflected by blood in the finger may also change correspondingly; and the processing module may determine the heart rate information of the human body by performing filtering, amplification and relevant algorithm routine processing on the electric signals. Similarly, when the blood oxygen status of the human body changes, the amount of the reflected light reflected by the blood in the finger may also change correspondingly, and the blood oxygen status information of the human body may be determined after processing the electric signals.
As illustrated in
By adoption of the solution, the intelligent wearable device may be used for user identification, for instance, used for payment identification, login identification and the like, and has the advantages of high anti-falsification, high accuracy, high convenience, etc. The specific application scenario of identification is not limited. For instance, identification may be applied in the financial system, the cardless member management system, the data encryption system, the security system, the insurance system, the examination system, the medical system, the military aviation system, etc.
As illustrated in
In the embodiments of the present disclosure, the processing module 15 further includes a heart rate simulation calculator 153 and is configured to determine the heart rate information and/or the blood oxygen status information of the human body according to the reflected light detected by the second photoelectric detection module, which includes: allowing the heart rate simulation calculator 153 to generate a heart rate simulation curve (as shown in
A specific structural form of the heart rate simulation calculator 153 is not limited. As illustrated in

Step S102: determining a first type of biometric information of the human body according to the detected transmitted light, and determining a second type of biometric information of the human body according to the detected reflected light.
In the above solution, a same light source is adopted to provide detection light for the first photoelectric detection module and the second photoelectric detection module, so that multiple types of biometric information can be simultaneously detected, and hence the efficiency of the intelligent wearable device in detecting the biometric information can be effectively improved.
For instance, the first type of biometric information may include venous information, and the second type of biometric information may include heart rate information and/or blood oxygen status information.
As illustrated in
Step S103: determining whether the venous information is matched with pre-stored venous information of the user; executing step S104 if the venous information is matched with the pre-stored venous information of the user; otherwise, executing step S105 if the venous information is not matched with the pre-stored venous information of the user.
Step S104: determining that the identity authentication of the user succeeds.
Step S105: determining that the identity authentication of the user does not succeed.
The intelligent wearable device may be used for user identification and has high safety and convenience.
For instance, after the step S104, the detection method may further comprise: performing a payment operation when the identity authentication of the user succeeds. The solution can improve the payment operation safety of the intelligent wearable device.
For instance, the heart rate information includes a heart rate simulation curve and/or heart rate values.
