The PPG sensor is a special sensor that uses photoplethysmography technology to detect human physiological parameters. The PPG sensor includes at least two sensor components, namely a light receiver and a light transmitter. In the related art, in order to detect the accuracy of the data, a solution of multiple light transmitters and multiple light receivers is used. Although it can meet the needs of sports and daily scenes, it increases the power consumption of the whole machine, thereby shortening the actual battery life of the user. Therefore, in order to solve the problems in the related art, the embodiment of the present disclosure provides a method for collecting physiological parameters. The method judges the wearing status of the user and starts the corresponding PPG sensor to collect physiological parameter data, thereby ensuring that the best data collection scheme is adopted in different usage scenarios, rather than directly adopting the scheme of multiple light transmitters and multiple light receivers to collect physiological data, thereby saving the power consumption of the whole machine.

As shown in FIG. 1 , FIG. 1 is a flow chart of a method for collecting physiological parameters shown in an embodiment of the present disclosure. The method for collecting physiological parameters can be performed by a wearable device. The wearable device can be a device with a heart rate detection function such as a bracelet or a watch. In this embodiment, the wearable device is configured with a sensor for collecting physiological parameter data. The sensor can be a PPG sensor. The method shown in FIG. 1 includes:

Step 101, determining the wearing status of the user.

In one embodiment, the wearing state of the user is the tightness of the wearable device when the user wears the wearable device. For example, if the wearable device is a smart watch worn on the wrist, the wearing state can be the user's sense of the smart watch worn on the wrist as appropriate, loose, or tight.

In one embodiment, the wearable device includes a tightness detection device, and a tightness measurement value can be obtained through the tightness detection device; the user's wearing status is judged based on the relationship between the tightness measurement value and a preset threshold.

The preset threshold value of tightness may be one or two or more. In a preferred embodiment, there are two preset threshold values of tightness, namely, a first threshold value and a second threshold value. In one embodiment, the first threshold value and the second threshold value may be empirical values. For example, the pressure value of the user wearing the smart bracelet in different wearing states is obtained by a pressure sensor installed on the smart bracelet, and the first threshold value and the second threshold value are obtained by statistically analyzing the pressure values obtained from various types of bracelets or other possible wearable devices. Among them, the first threshold value is a reference value when the user's wearing state is tight, and the second threshold value is a reference value when the user's wearing state is loose.

When the tightness measurement value is not greater than the first threshold, the user's wearing state is judged to be tight, and the PPG (photoplethysmography) signal collected at this time is of average or even poor quality; when the tightness measurement value is not less than the second threshold, the user's wearing state is judged to be loose, and the PPG (photoplethysmography) signal collected at this time is of average or even poor quality; when the tightness measurement value is between the first threshold and the second threshold, the user's wearing state is judged to be appropriate, and the PPG (photoplethysmography) signal collected at this time is of good quality. It can be understood that the better the quality of the PPG signal, the more accurate the physiological parameters calculated by it.

In one embodiment, the tightness detection device may be, for example, an indium tin oxide (ITO) coated electrode. The first measurement value is obtained through the indium tin oxide (ITO) coated electrode, and the tightness measurement value is obtained according to the first measurement value. When the tightness measurement value is not greater than the first threshold, the user's wearing state is tight, and the quality of the collected PPG signal is generally or even poor. When the tightness measurement value is not less than the second threshold, the user's wearing state is loose, and the quality of the collected PPG signal is generally or even poor. When the tightness measurement value is between the first threshold and the second threshold, the user's wearing state is appropriate, and the quality of the collected PPG signal is good. In this embodiment, an indium tin oxide (ITO) coated electrode is set in the possible area where the wearable device contacts the skin. When the user's wearing state is different, the contact area between the indium tin oxide (ITO) coated electrode and the skin is different, and the corresponding impedance value is also different. The tightness measurement value is determined according to the impedance values measured in different wearing states after the user wears the wearable device.

In one embodiment, the tightness detection device includes a pressure sensor and an indium tin oxide (ITO) coated electrode. Before obtaining the tightness measurement value, it is necessary to obtain a first measurement value through the indium tin oxide (ITO) coated electrode and a second measurement value through the pressure sensor; then the tightness measurement value is obtained by weighting the first measurement value and the second measurement value. When the tightness measurement value is not greater than the first threshold, the user's wearing state is tight, and the quality of the collected PPG signal is generally or even poor. When the tightness measurement value is not less than the second threshold, the user's wearing state is loose, and the quality of the collected PPG signal is generally or even poor. When the tightness measurement value is between the first threshold and the second threshold, the user's wearing state is appropriate, and the quality of the collected PPG signal is good.

In this embodiment, compared with the single use of pressure sensors or indium tin oxide ITO coated electrodes to determine the user's wearing status, in the embodiment of the present disclosure, indium tin oxide ITO coated electrodes are set in the possible area where the wearable device contacts the skin. When the user's wearing status is different, the contact area between the indium tin oxide ITO coated electrode and the skin is different, and the corresponding impedance value is also different. At the same time, when the user's wearing status is different, the pressure value detected by the pressure sensor is also different. In the actual wearing state of the wearable device, the wearable device senses not only the pressure value, but also the contact area between the wearable device and the skin. Compared with the results obtained by a single method, the embodiment of the present disclosure obtains the measurement value of tightness by combining the impedance value and the pressure value, which will be better in terms of data reliability and accuracy.

In a preferred embodiment, by weighting the first measurement value and the second measurement value, the weighting coefficient of the first measurement value and the second measurement value can be determined from the actual application. For example, in the actual use of the wearable device, by obtaining the first measurement value and the second measurement value of the user in different wearing states, and the relationship between the first measurement value and the second measurement value and the measurement value of tightness, the weighting coefficient of the first measurement value and the second measurement value is obtained through data statistical analysis.

Step 102, according to the user's wearing status, start the corresponding sensor to collect physiological parameter data; wherein, the wearable device is configured with multiple sensors, each sensor includes a light receiver and a light transmitter, and the light receiver and the light transmitter are arranged at different positions of the wearable device.

As shown in FIG2 , FIG2 is a schematic diagram of the biosensor distribution structure of a wearable device shown in an embodiment of the present disclosure. Among them, the biosensor can be a PPG sensor, and the wearable device is provided with a plurality of sensor components, each sensor component is a light receiver or a light transmitter, and the light receiver and the light transmitter are arranged at different positions of the wearable device at intervals. It can be understood that the PPG sensor includes a plurality of sensor components, and at least two sensor components can be selected as needed to form a PPG sensor, wherein the sensor components constituting the PPG sensor include both a light receiver and a light transmitter.

In one embodiment, when the user's wearing state is appropriate, a first (A ₁ ) number of light emitters are selected from a plurality of light emitters, and a second (B ₁ ) number of light receivers are selected from a plurality of light receivers; a sensor composed of the selected light emitters and light receivers is started to collect physiological parameter data.

In this embodiment, when the user's wearing state is appropriate, the PPG signal collected at this time has good quality. The better the quality of the PPG signal, the more accurate the physiological parameters calculated by it. Therefore, a combination of a smaller number of light emitters and receivers can be selected to collect physiological parameter data, for example, _A1 light emitters and B1 light receivers adjacent to the light emitters are selected to form a PPG sensor to collect physiological parameter data.

Multiple sensor components are distributed in different areas of the wearable device. Therefore, when it is detected that the user's wearing status is suitable, loose, or tight, the sensor components in different areas are activated to form the corresponding PPG sensors to collect physiological parameter data, which can effectively improve the utilization efficiency of the PPG sensor and also help reduce the power consumption of the PPG sensor.

In one embodiment, when the user's wearing state is inappropriate and the user's wearing state is loose, a third (A ₂ ) number of light emitters is selected from the plurality of light emitters, and a fourth (B ₂ ) number of light receivers is selected from the plurality of light receivers, wherein the third number is not less than the first number, and the fourth number is not less than the second number. A sensor composed of the selected light emitters and light receivers is activated to collect physiological parameter data.

In this embodiment, when the user's wearing state is loose, the quality of the PPG signal collected at this time is generally or even poor. Therefore, a relatively large number of light emitters and receiver combinations can be selected to collect physiological parameter data. For example, A ₂ number of light emitters and B ₂ number of adjacent light receivers and non-adjacent light receivers are selected to form a PPG sensor to collect multiple data and improve the accuracy of the physiological parameter data.

In one embodiment, when the user's wearing state is inappropriate and when the user's wearing state is tight, a fifth (A ₃ ) number of light emitters are selected from the multiple light emitters, and a sixth (B ₃ ) number of light receivers are selected from the multiple light emitters, wherein the fifth number is not less than the first number, and the sixth number is not less than the second number, and the sensor composed of the selected light emitters and light receivers is started to collect physiological parameter data.

In this embodiment, when the user's wearing state is tight, the quality of the PPG signal collected at this time is generally or even poor. Therefore, a relatively large number of light emitters and receivers can be selected to collect physiological parameter data. For example, A ₃ light emitters and B ₃ non-adjacent light receivers are selected to form a PPG sensor, so as to collect physiological parameter data, improve the use efficiency of the PPG sensor, and also help to reduce the power consumption of the PPG sensor.

In one embodiment, as shown in FIG2 , a plurality of light receivers and a plurality of light transmitters are configured in the wearable device, wherein the light receivers and the light transmitters are arranged at different positions of the wearable device at intervals. At least one light receiver and at least one light transmitter form a PPG sensor, that is, a PPG sensor includes at least two sensor components, wherein the sensor components constituting the sensor include both light receivers and light transmitters. As shown in FIG2 , the distance between each light receiver and an adjacent light transmitter can be the same as D1, and the distance between each light receiver and a non-adjacent light transmitter can be the same as D2.

It should be noted that, in some preferred embodiments, the light receiver may be a photodiode, and the light transmitter may be a three-color LED lamp and/or a single-color LED lamp.

In a possible implementation, the corresponding sensors can be activated to collect physiological parameter data according to the different wearing states of the user. By activating the corresponding light transmitter and light receiver, the user's physiological parameter data in each wearing state, such as heart rate, blood oxygen, blood pressure, etc., can be detected. A large amount of research data shows that the measurement of the user's heart rate requires a certain distance between the light receiver and the light transmitter. Therefore, when choosing to activate the PPG sensor on the wearable device, in order to test the user's heart rate in each wearing state, it is necessary to activate the light receiver and light transmitter in the corresponding area. When the user's wearing state is appropriate, the sensor composed of the selected first number of light emitters and the second number of light receivers is started, and the distance between the first number of light emitters and the second number of light receivers is a short distance, that is, the short-distance light emitter and light receiver combination is started; when the user's wearing state is inappropriate and the user's wearing state is loose, the sensor composed of the selected third number of light emitters and the fourth number of light receivers is started, and the distance between the third number of light emitters and the fourth number of light receivers includes a long distance and a short distance, that is, both the long-distance and short-distance light emitter and light receiver combinations are started; when the user's wearing state is inappropriate and the user's wearing state is tight, the sensor composed of the selected fifth number of light emitters and the sixth number of light receivers is started, and the distance between the fifth number of light emitters and the sixth number of light receivers is a long distance, that is, the long-distance light emitter and light receiver combination is started.

For example, when the user's wearing state is appropriate, the PPG signal collected at this time has good quality, therefore, one optical transmitter and one adjacent short-distance optical receiver are selected, and another optical transmitter and an adjacent short-distance optical receiver arranged opposite to the above-selected sensor component are selected, and a sensor composed of four sensor components (A ₁ =2, B ₁ =2) is formed to collect physiological parameters; when the user's wearing state is inappropriate and the user's wearing state is loose, the PPG signal collected at this time has general or even poor quality, therefore, one optical transmitter and at least one adjacent short-distance optical receiver and at least one non-adjacent long-distance optical receiver are selected, and another optical transmitter and an adjacent short-distance optical receiver and a non-adjacent long-distance optical receiver arranged opposite to the above-selected sensor component are selected, and a sensor composed of at least six sensor components (A ₂ =2, B ₂ =4) to collect physiological parameters; when the user's wearing state is inappropriate and when the user's wearing state is tight, the quality of the PPG signal collected at this time is generally or even poor, therefore, one optical transmitter and at least one long-distance optical receiver not adjacent to it are selected, and another optical transmitter and a long-distance optical receiver not adjacent to it are selected to be arranged opposite to the above-selected sensor component, and at least four sensor components are used to form a sensor (A ₂ =2, B ₂ =2) to collect physiological parameters.

In summary, by judging the wearing status of the user; according to the wearing status of the user, starting the corresponding sensor to collect physiological parameter data; wherein, the wearable device is configured with multiple sensors, each sensor includes a light receiver and a light transmitter, and the light receiver and the light transmitter are arranged at different positions of the wearable device, to ensure that the best data collection scheme is adopted in different usage scenarios, rather than directly adopting the scheme of multiple light transmitters and multiple light receivers to collect physiological data, thereby saving the power consumption of the whole machine.

The following is an explanation using a specific embodiment, see Figure 2. Take the case where the light receiver is a photodiode and the light transmitter is a three-color lamp as an example. In the figure, 2, 3, 4, and 5 are three-color lamps (red, green, and infrared), 6, 7, 8, and 9 are photodiodes, 1 is a pressure sensor, and the gray disk area is the indium tin oxide ITO coating electrode area. Among them, the distance between each three-color lamp and the adjacent photodiode is the same as D1, and the distance between each three-color lamp and the non-adjacent photodiode is also the same as D2. Among them, D2 is greater than D1.

When the user's wearing state is appropriate, one tricolor light is randomly selected from multiple tricolor lights, for example, tricolor light No. 2. Adjacent to tricolor light No. 2 is photodiode No. 6 or No. 7. When photodiode No. 6 is selected, only photodiode No. 8 and tricolor light No. 4 are in the symmetrical area symmetrical to tricolor light No. 2 and photodiode No. 6. Here, the symmetrical area refers to the diameter of the center of the circle as the symmetry axis, and the symmetry axis is parallel to the connection line between tricolor light No. 2 and photodiode No. 6. When photodiode No. 7 is selected, the principle is the same. Tricolor light No. 4 and photodiode No. 9 need to be selected accordingly, and the selected tricolor lights and diodes are started as sensors when the wearing state is appropriate, so as to collect physiological parameter data. Here, the startup order of the tricolor lights and photodiodes is not limited. It can be understood that the startup order of the light transmitter is no later than that of the light receiver.

When the user's wearing state is inappropriate and when the user's wearing state is loose, it is necessary to select all the photodiodes and three-color lights in No. 2-9 for startup, wherein No. 2-9 refers to the 8 sensor components from No. 2 to No. 9, and the combination of three-color lights and photodiodes may include short-distance 2-6, 2-7, 3-7, 3-8, 4-8, 4-9, 5-6, 5-9, and long-distance 2-8, 2-9, 3-6, 3-9, 4-6, 4-7, 5-7, 5-8. All the photodiodes and three-color lights are started as sensors when the wearing state is loose to collect physiological parameter data. The startup sequence is not limited. It can be understood that the startup sequence of the light transmitter is no later than that of the light receiver.

When the user's wearing state is inappropriate and the user's wearing state is tight, a tricolor lamp is randomly selected from multiple tricolor lamps, for example, tricolor lamp No. 3, and then photodiodes that are not adjacent to tricolor lamp No. 3 are selected, namely, photodiodes No. 6 and No. 9. Then the diameter parallel to the line connecting photodiodes No. 6 and No. 9 is determined as the symmetry axis, and then the symmetric area is divided. According to the divided symmetric area, tricolor lamp No. 5 and photodiodes No. 7 and No. 8 in the symmetric area that are symmetrical to tricolor lamp No. 3 and photodiodes No. 6 and No. 9 are selected, and the selected tricolor lamp and diode are activated as sensors when the wearing state is tight, so as to collect physiological parameter data. It can be understood that the activation order of the light transmitter is no later than that of the light receiver.

It should be emphasized that in other embodiments where the layout of the optical receivers and optical transmitters is not symmetrical, the specific sensor can be determined by referring to the wearing state described above and the number and position relationship of the optical receivers and optical transmitters that constitute the sensor. The above is only an exemplary embodiment.
