Detailed implementation manners
[0038] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more of the associated listed items.
[0039] Currently, wearable devices use photoplethysmography (PPG) to monitor user data. Photoplethysmography needs to emit light to human tissues and blood through a light-emitting module and receive the reflected light passing through human tissues and blood through a light receiver. When blood flows, the absorption amount of hemoglobin in blood vessels for light of a specific wavelength (such as green light) will change, so that part of the light emitted by the light-emitting module to the skin is absorbed and the other part of the light is reflected. By converting the reflected light received by the light receiver into an electrical signal and extracting the alternating current signal in the electrical signal, data such as heart rate and blood oxygen can be detected as health data, and usage data such as the wearing of the wearable device can be detected.
[0040] In the related art, a wearable device is provided, which includes two light-emitting modules and two light receivers. Both of the two light-emitting modules are used to emit green light, red light, and infrared light. When monitoring user data, the two light-emitting modules simultaneously emit green light, red light, and / or infrared light to the user, and the corresponding light receivers receive the reflected light to monitor the user data. For example, the two light-emitting modules simultaneously emit green light for heart rate detection, the two light-emitting modules simultaneously emit red light and infrared light for blood oxygen detection, and the two light-emitting modules simultaneously emit infrared light for wearing detection. However, when monitoring user data, since the two light-emitting modules emit light simultaneously, a relatively large power consumption is generated, resulting in the problem of high power consumption of the wearable device.
[0041] Based on this, the present disclosure provides a wearable device, which includes a first light-emitting module and a second light-emitting module. The second light-emitting module can only emit green light and cannot emit red light and infrared light. Since the second light-emitting module does not need to emit red light and infrared light when monitoring user data, the power consumption of the second light-emitting module is reduced, thereby reducing the power consumption of the wearable device. Moreover, since the second light-emitting module only needs to emit green light, the cost of the second light-emitting module is reduced, thereby reducing the cost of the wearable device. At the same time, since the light receiver is located on the same side of the first light-emitting module and the second light-emitting module, the interference with the signal received by the light receiver is reduced, thereby improving the accuracy of data monitoring of the wearable device.
[0042] An exemplary embodiment of the present disclosure provides a wearable device, as Figure 1 shown, the wearable device includes a bottom case 10, a first light-emitting module 20, a second light-emitting module 30, and at least one light receiver 40. The first light-emitting module 20, the second light-emitting module 30, and the light receiver 40 are disposed on the bottom case 10. The second light-emitting module 30 is arranged side by side with the first light-emitting module 20 in a first direction. At least one light receiver 40 is located on the same side of the first light-emitting module 20 and the second light-emitting module 30. The first light-emitting module 20 is used to emit green light and is also used to emit red light and / or infrared light. The second light-emitting module 30 is used to emit green light.
[0043] In this embodiment, the wearable device includes a bottom case, a first light-emitting module, a second light-emitting module, and at least one light receiver disposed on the bottom case. The second light-emitting module is arranged side by side with the first light-emitting module in a first direction, and at least one light receiver is located on the same side of the first light-emitting module and the second light-emitting module. By the first light-emitting module emitting green light, red light, and / or infrared light, and the second light-emitting module emitting green light, it is avoided that the wearable device needs the first light-emitting module and the second light-emitting module to emit red light and infrared light simultaneously when monitoring the user's data, thereby reducing the power consumption of the wearable device. Moreover, since the second light-emitting module only needs to emit green light, the cost of the second light-emitting module is reduced, thereby reducing the cost of the wearable device. At the same time, since the light receiver is located on the same side of the first light-emitting module and the second light-emitting module, the interference generated by the signal received by the light receiver is reduced, thereby improving the accuracy of data monitoring of the wearable device.
[0044] In one embodiment, as Figure 2 shown, at least one light receiver 40 includes a first light receiver 41 and a second light receiver 42. The first light receiver 41 is arranged side by side with the first light-emitting module 20 in a second direction. The second light receiver 42 is arranged side by side with the second light-emitting module 30 in the second direction. Wherein, the second direction is perpendicular to the first direction.
[0045] In this embodiment, by providing two light receivers, one or two light receivers can be used to receive the reflected light when monitoring different data, thereby improving the accuracy of monitoring of the wearable device. Moreover, by making the first light receiver and the second light receiver perpendicular to the first light-emitting module and the second light-emitting module respectively in the arrangement direction, the distance between the first light-emitting module and the first light receiver and between the second light-emitting module and the second light receiver is minimized, which is beneficial to reducing the light intensity attenuation caused by the too long light path and improving the reliability of monitoring of the wearable device.
[0046] Exemplarily, after the user wears the wearable device, the first direction can be the direction where the user's arm is located.
[0047] In one embodiment, as Figure 3 shown, the first light-emitting module 20 includes a first green light-emitting element 21, a red light-emitting element 22, and an infrared light-emitting element 23. Wherein, in the second direction, both the red light-emitting element 22 and the infrared light-emitting element 23 are located on the side of the first green light-emitting element 21 away from the first light receiver 41.
[0048] In this embodiment, since the closer the first green light emitting element is to the optical receiver, the higher the accuracy of the monitored data, the first green light emitting element is arranged closer to the first optical receiver. Since the closer the red light emitting element and the infrared light emitting element are to the optical receiver, the greater the interference to the monitored data, the red light emitting element and the infrared light emitting element are arranged farther from the first optical receiver. By arranging the red light emitting element and the infrared light emitting element farther from the first optical receiver and the first green light emitting element closer to the first optical receiver, the interference received by the first optical receiver is reduced, thereby improving the accuracy of the monitoring of the wearable device.
[0049] It can be understood that when the first optical receiver 41 and the second optical receiver 42 are located on different sides of the first light emitting module 20 and the second light emitting module 30, if the first green light emitting element 21 is close to the first optical receiver 41 and the red light emitting element 22 and the infrared light emitting element 23 are far from the first optical receiver 41 and close to the second optical receiver 42, the interference received by the second optical receiver 42 is large and the accuracy of the data monitored by the wearable device is low. If the first green light emitting element 21 is close to the second optical receiver 42 and the red light emitting element 22 and the infrared light emitting element 23 are close to the first optical receiver 41 and far from the second optical receiver 42, the interference received by the first optical receiver 41 is large and the accuracy of the data monitored by the wearable device is low. By arranging the first optical receiver 41 and the second optical receiver 42 on the same side of the first light emitting module 20 and the second light emitting module 30, and making the first green light emitting element 21 close to the first optical receiver 41, and the red light emitting element 22 and the infrared light emitting element 23 far from both the first optical receiver 41 and the second optical receiver 42 at the same time, the accuracy of the monitoring of the wearable device is further improved.
[0050] In one embodiment, the red light emitting element 22 and the infrared light emitting element 23 are arranged side by side in the first direction.
[0051] In this embodiment, since the wavelengths of red light and infrared light are different, by arranging the red light emitting element and the infrared light emitting element side by side, the red light emitted by the red light emitting element and the infrared light emitted by the infrared light emitting element can be reflected onto the second optical receiver at the same time. By the second optical receiver receiving the reflected red light and the reflected infrared light at the same time, it is convenient to monitor different data in various situations, thereby improving the accuracy of the monitoring of the wearable device. At the same time, since the first optical receiver is arranged side by side with the first light emitting module in the second direction and the red light emitting element and the infrared light emitting element are arranged side by side in the first direction, the red light emitting element and the infrared light emitting element can be farthest from the first optical receiver, thereby further improving the accuracy of the monitoring of the wearable device.
[0052] Exemplarily, the distance between the red light emitting element 22 and the second light emitting module 30 is greater than the distance between the infrared light emitting element 23 and the second light emitting module 30.
[0053] In one embodiment, the first light emitting module 20 includes a first green light emitting element 21, a red light emitting element 22, and an infrared light emitting element 23. Among them, in the first direction, both the red light emitting element 22 and the infrared light emitting element 23 are located on the side of the first green light emitting element 21 away from the second light emitting module 30.
[0054] In this embodiment, since the closer the red light emitting element and the infrared light emitting element are to the light receiver, the greater the interference to the data, the red light emitting element and the infrared light emitting element are arranged farther away from the second light emitting module so that the red light emitting element and the infrared light emitting element are farther away from the second light receiver. By arranging the red light emitting element and the infrared light emitting element farther away from the second light receiver, the interference received by the second light receiver is reduced, thereby improving the accuracy of the monitoring of the wearable device.
[0055] In one embodiment, the red light emitting element 22 and the infrared light emitting element 23 are arranged side by side in the second direction.
[0056] In this embodiment, since the wavelengths of red light and infrared light are different, by arranging the red light emitting element and the infrared light emitting element side by side, the red light emitted by the red light emitting element and the infrared light emitted by the infrared light emitting element can be simultaneously reflected onto the second light receiver. By the second light receiver simultaneously receiving the reflected red light and the reflected infrared light, it is convenient to monitor different data in various situations, thereby improving the accuracy of the monitoring of the wearable device.
[0057] In one embodiment, as Figure 4 shown, the light receiver 40 is provided as one, and in the first direction, the light receiver 40 is located between the first light emitting module 20 and the second light emitting module 30.
[0058] In this embodiment, by using one light receiver to receive the reflected light, not only can the volume of the wearable device be reduced to make the wearable device more compact, but also the cost of the wearable device can be reduced.
[0059] Exemplarily, the first light emitting module 20 includes a first green light emitting element 21, a red light emitting element 22, and an infrared light emitting element 23, and the second light emitting module 30 includes a second green light emitting element 31. Among them, the red light emitting element 22 and the infrared light emitting element 23 are arranged on the side away from the light receiver 40.
[0060] In one embodiment, as Figure 5As shown, the first light-emitting module 20 includes a first green light-emitting element 21, a red light-emitting element 22, and an infrared light-emitting element 23. The second light-emitting module 30 includes a second green light-emitting element 31. As Figure 6 shown, the anodes of the first green light-emitting element 21, the second green light-emitting element 31, the red light-emitting element 22, and the infrared light-emitting element 23 are all used to connect to the power supply Vin. The wearable device further includes a processing unit 50, and multiple first ends of the processing unit 50 are respectively connected to the cathodes of the first green light-emitting element 21, the second green light-emitting element 31, the red light-emitting element 22, and the infrared light-emitting element 23.
[0061] In this embodiment, since there are various types of data that the wearable device can monitor, by connecting the processing unit to the first light-emitting module and the second light-emitting module, the first light-emitting module and the second light-emitting module emit different colors of light to monitor the corresponding data. By connecting the first green light-emitting element, the second green light-emitting element, the red light-emitting element, and the infrared light-emitting element between the processing unit and the power supply, the processing unit only needs to output a level through the corresponding first end to make the light-emitting element emit the corresponding color of light, thereby reducing the complexity of data monitoring.
[0062] In one embodiment, as Figure 7 shown, the optical receiver 40 includes a photosensitive diode. The cathode of the photosensitive diode is used to connect to the ground terminal GND, and the anode of the photosensitive diode is connected to the second end of the processing unit 50.
[0063] In this embodiment, when the photosensitive diode receives the reflected light, the photosensitive diode conducts to make the second end of the processing unit conduct with the ground terminal. The processing unit converts the reflected light received by the photosensitive diode into an electrical signal and extracts the alternating current signal in the electrical signal to monitor the data, thereby reducing the complexity of data monitoring.
[0064] In one embodiment, the first light-emitting module 20 includes a first green light-emitting element 21, a red light-emitting element 22, and an infrared light-emitting element 23. The second light-emitting module 30 includes a second green light-emitting element 31. At least one optical receiver 40 includes a first optical receiver 41 and a second optical receiver 42. Among them, the first green light-emitting element 21, the second green light-emitting element 31, the first optical receiver 41, and the second optical receiver 42 are used for heart rate detection. The red light-emitting element 22, the infrared light-emitting element 23, and the second optical receiver 42 are used for blood oxygen detection. The infrared light-emitting element 23, the first optical receiver 41, and the second optical receiver 42 are used for wearing detection.
[0065] In this embodiment, since blood has a high absorption rate for the wavelength of green light, green light is emitted by the first green light emitting element and the second green light emitting element, and the reflected light is received by the first light receiver and the second light receiver, and the reflected light can better reflect the change in blood flow to improve the accuracy of heart rate detection. Since oxygenated hemoglobin and deoxygenated hemoglobin have different absorption rates for red light and infrared light, red light and infrared light are emitted by the red light emitting element and the infrared light emitting element, and the reflected light is received by the second light receiver, and the reflected light can better reflect the difference in the absorption rate of red light and infrared light to improve the accuracy of blood oxygen monitoring. Since infrared light has a strong ability to penetrate the skin, emitting infrared light by the infrared light emitting element and receiving reflected light by the first light receiver and the second light receiver can reflect whether the wearable device is worn to improve the accuracy of wearing detection.
[0066] An exemplary embodiment of the present disclosure provides a wearable device, Figures 5 to 7 As shown, the wearable device includes a bottom shell 10, a first light emitting module 20, a second light emitting module 30, a first light receiver 41, and a second light receiver 42 arranged on the bottom shell 10, and a processing unit 50. The first light emitting module 20 is arranged side by side with the second light emitting module 30 in the first direction, the first light receiver 41 is arranged side by side with the first light emitting module 20 in the second direction, and the second light receiver 42 is arranged side by side with the second light emitting module 30 in the second direction. The first light emitting module 20 includes a first green light emitting element 21, a red light emitting element 22, and an infrared light emitting element 23. The second light emitting module 30 includes a second green light emitting element 31. In the second direction, the red light emitting element 22 and the infrared light emitting element 23 are both located on the side of the first green light emitting element 21 away from the first light receiver 41, and the red light emitting element 22 and the infrared light emitting element 23 are arranged side by side along the first direction, and the first direction is perpendicular to the second direction. Among them, the anode of the first green light emitting element 21, the anode of the second green light emitting element 31, the anode of the red light emitting element 22 and the anode of the infrared light emitting element 23 are all used to connect to the power supply Vin, and the cathode of the first green light emitting element 21, the cathode of the second green light emitting element 31, the cathode of the red light emitting element 22 and the cathode of the infrared light emitting element 23 are respectively connected to multiple first ends of the processing unit 50. The second end of the processing unit 50 is connected to the anode of the first light receiver 41 and the anode of the second light receiver 42, and the cathode of the first light receiver 41 and the cathode of the second light receiver 42 are used to connect to the ground terminal GND.
[0067] Exemplarily, the working principle of the wearable device is described as follows: When it is necessary to detect the heart rate, the processing unit 50 controls the first green light emitting element 21 and the second green light emitting element 31 to emit green light, and the reflected light is received through the first light receiver 41 and the second light receiver 42. When it is necessary to detect blood oxygen, the processing unit 50 controls the red light emitting element 22 and the infrared light emitting element 23 to emit red light and infrared light, and the reflected light is received through the second light receiver 42. When it is necessary to detect whether the wearable device is worn, the processing unit 50 controls the infrared light emitting element 23 to emit infrared light, and the reflected light is received through the first light receiver 41 and the second light receiver 42.
[0068] In one exemplary embodiment, a wearable device is provided. The wearable device is, for example, a smart watch, a smart bracelet, or the like.
