The contact capacitance value based on the wearing state detection is higher than the contact capacity value detected by the non-wearing state detection, and the change in the contact capacitance value is more obvious. Therefore, the present invention can accurately detect the contact capacitance value detected by comparing with the non-wearing reference value. The wearable state of the smart wearable device provides accurate detection data to enhance the user experience.

Referring to FIG. 1, in an embodiment, a wear status detecting method of the smart wearable device includes the following steps:

Step S10: Obtain an unworn reference value of the smart wearable device;

In this embodiment, the smart wearable device can be a smart wristband, a smart watch, etc., and has various detection functions such as steps, sleep, heart rate, body temperature, illumination, environmental noise, diet, and the like, and can be connected with a mobile terminal such as a mobile phone. Wireless connection such as tablet computers and smart homes such as air conditioners. Therefore, the present invention can directly execute the corresponding detection program by the smart wearable device, or the mobile terminal can acquire various capacitance values detected by the smart wearable device, thereby controlling the detection program.

In a specific embodiment, referring to FIG. 2, the step S10 includes:

Step S101, after the smart wearable device is powered on, perform initialization;

In this embodiment, after the smart wearable device is powered on, the smart wearable device automatically enters an initialization procedure after a predetermined time, such as 15 seconds, to obtain an unworn reference value.

Step S102, after the initialization is completed, the contact capacitance value in the first period is read, and the contact capacitance value is taken as the unworn reference value.

In this embodiment, the capacitance generated by the contact between the user skin and the smart wearable device is read three times in one cycle, and the capacitance values obtained by the three times are summed to obtain the contact capacitance value. Of course, the present invention does not limit the number of readings of the values in one cycle. In other embodiments, the number of times can be reasonably set according to actual needs.

In the preferred embodiment, after the smart wearable device completes initialization, the contact capacitance value in the first period is read, and the contact capacitance value is taken as an unworn reference value of the user wearing the smart wearable device, such as 4850±100.

Step S20: Read a contact capacitance value generated by contact between the user skin and the smart wearable device in one cycle every predetermined time, and calculate a difference between the contact capacitance value and the unworn reference value;

In this embodiment, after the reference value is not worn, the contact capacitance generated by the contact between the user skin and the smart wearable device in one cycle can be read every 10 seconds, and the read contact capacitance value is calculated. The difference between the reference values is not worn, and the wearing state of the smart wearable device, such as the worn state or the unworn state, is determined according to the size range of the difference.

Step S30: If the difference values satisfy the first preset range within the predetermined number of wearing detections, determine that the smart wearable device is in a wearing state.

In the preferred embodiment, the predetermined number of times of wearing can be set to 20 times, etc., and is not limited in particular; and the preset range that the difference M satisfies may be: the difference M>800 or 300<M≤800, of course, the specific numerical range and It is not limited to this embodiment.

The wearable state detecting method of the smart wearable device provided by the present invention reads the contact capacitance value generated by the contact between the smart wearable device and the user's skin in one cycle every predetermined time, and calculates the contact capacitance value and the unworn value. The difference between the reference values determines whether the wearable state of the smart wearable device is in a worn or unworn state if the difference satisfies the first preset range within a predetermined number of wear detections. The contact capacitance value based on the wearing state detection is higher than the contact capacity value detected by the non-wearing state detection, and the change in the contact capacitance value is more obvious. Therefore, the present invention can accurately detect the contact capacitance value detected by comparing with the non-wearing reference value. The wearable state of the smart wearable device provides accurate detection data to enhance the user experience.

In the first embodiment, as shown in FIG. 3, on the basis of the above-mentioned FIG. 1 or FIG. 2, the step S30 includes:

Step S301, determining whether the difference is greater than a first predetermined value;

Step S302, if the difference is greater than the first predetermined value, increase the number of times of wearing detection by a first preset value, and record the current wearing value;

In this embodiment, it is determined whether the difference is greater than the first predetermined value. If the condition is met, that is, M>800, the current state of the smart wearable device may be determined to be tight, and at this time, the number N of wear detections is increased. The first predetermined value is 5: N + 5, and the current wearing value is recorded.

Step S303, when the number of times of wearing detection exceeds a predetermined number of times, it is determined that the smart wearable device is in a wearing state.

In this embodiment, when the number of times of wearing the detection N+5 exceeds a predetermined number of times, such as 20, it is determined that the smart wearable device is in the wearing state. It should be understood that if the number of wearing detections increases to 30, there is no need to increase the number of wearing detections. The specific numerical values in this embodiment are only used to help the understanding of the present invention and are not specifically limited.

In the second embodiment, as shown in FIG. 4, on the basis of the foregoing FIG. 3, the step S301 further includes:

Step S304, if the difference is less than or equal to the first predetermined value, determining whether the difference is greater than a second predetermined value;

Step S305, if the difference is greater than the second predetermined value and less than or equal to the first predetermined value, determining that the current state is a loose band, increasing the number of wearing detections by a second preset value, and recording the current Wear value

In this embodiment, when it is determined that M≤800, it is further determined whether the difference M is greater than a second predetermined value, that is, whether M satisfies the following condition: 300<M≤800, if the condition is met, it is determined that the smart wearable device is currently The state is loose. At this time, the number N of wear detections is increased by a second predetermined value such as 4:N+4, and the current wearing value is recorded. The second preset value is smaller than the first preset value. In this way, in the tight state, the wearing detection can be accelerated.

Step S306, when the number of times of wearing detection exceeds a predetermined number of times, it is determined that the smart wearable device is in a wearing state.

In the preferred embodiment, when the number of times of wearing the detection N exceeds a predetermined number of times, such as 20, it indicates that the difference is within the preset range within the predetermined number of wearing detections, and then the smart wearable device can be determined to be in the wearing state.

In this embodiment, according to the size range of the difference, it is specifically determined whether the smart wearable device, such as the wristband, is in a tight band or a loose band state, so that when the wristband is in a loose state, the light display, voice prompt, or Vibrating reminders and other means to remind the user that the bracelet is in a loose state. To improve the detection accuracy of the bracelet, the wristband should be worn in time; the mobile terminal can also be used to remind the user to wear the wristband in time.
