Detailed ways

The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

Most products only rely on the reflection signal of the green light or infrared light that comes with the heart rate monitoring module to determine whether the product is worn. Once the product is placed on other objects, the light from the green or infrared light can be reflected, the product is considered to be worn , Still working, getting inaccurate monitoring data, and wasting power. Based on the above technical problems, this embodiment provides a state detection method. Please refer to FIG. 1 for details. FIG. 1 is a flowchart of a state detection method provided by an embodiment of the application, which specifically includes:

S110: Obtain the optical signal collected by the optical sensor;

Specifically, a light sensor is provided in the wearable device, and the light sensor is used to collect light signals.

S120: When the reflected light is detected according to the light signal, control the motor to turn on;

The purpose of this step is to roughly measure the wearing condition and determine the conditions under which the motor is turned on. When the reflected light is detected, it is determined to be blocked, and the control motor is turned on at this time. In this embodiment, the position and number of the motor settings are not limited, and the user can customize the settings.

The reflected light is the light reflected from the obstacle after the light sensor emits the light. The obstacle may be the user's wrist or other objects. According to the light signal, it is determined that the light reflection is detected, and the motor is controlled to turn on at this time.

S130: Acquire acceleration information of the motor collected by the acceleration sensor;

When the motor is controlled to be turned on in step S120, the motor starts to vibrate. At this time, the intensity, frequency, etc. of the motor vibration are not limited in this embodiment, and the user can customize the settings, as long as the purpose of this embodiment can be achieved.

The wearable device in this embodiment is provided with an acceleration sensor for collecting acceleration information after the motor vibrates. It is understandable that when the user is not wearing the wearable device, the motor vibration amplitude a1 corresponds to the obtained acceleration information b1; when the user successfully wears the wearable device, the motor vibration is greatly damped, and the motor vibration amplitude a2, the corresponding acceleration information b2, where a1>a2, b1>b2.

S140: Use acceleration information and preset calibration vibration characteristic information to match to determine the wearing state of the wearable device.

In this step, the acceleration information is matched with the preset calibration vibration characteristic information to determine the wearing state corresponding to the acceleration information. For example, the calibration vibration characteristic information includes the wearing state C corresponding to c, d, e, f, c, the wearing state D corresponding to d, the wearing state E corresponding to e, and the wearing state F corresponding to f. When the acceleration information is successfully matched with c, the wearable state of the wearable device is determined to be C; when the acceleration information is successfully matched with d, the wearable state of the wearable device is determined to be D; when the acceleration information is successfully matched with e, the wearable state is determined The wearing state of the device is E; when the acceleration information matches f successfully, it is determined that the wearing state of the wearable device is F. The matching method is not limited in this embodiment, and it may be within a range or a fixed value, as long as it can achieve the purpose of this embodiment.

Further, the preset method for calibrating the vibration characteristic information includes: reading the calibration instruction after the wearable device is correctly worn; obtaining the calibration acceleration information according to the calibration instruction; determining the standard vibration based on the calibration acceleration information and the preset standard acceleration information Characteristic information.

Among them, the preset standard acceleration information is information for all users. It is understandable that since the calibration acceleration information determined by each user is different, all users determine the standard vibration corresponding to the user based on the preset standard acceleration information. Characteristic information. For example, when the preset standard acceleration information is p and q, that is to say, when the acceleration is greater than or equal to p, it is not worn, if the acceleration is between p and q, the wear is not standard, and when the acceleration is less than or equal to q, it is worn; then The user obtains the unworn acceleration as p1 and the worn acceleration as q1 according to the first calibration instruction. At this time, p2 is re-determined according to p and p1, q2 is re-determined according to q and q1, and p2 and q2 are determined as standard vibration characteristic information. Among them, this embodiment does not limit the number of accelerations and the manner of determining the standard vibration characteristic information, and the user can customize the settings.

Based on the above technical solution, this embodiment uses the light signal to determine when the reflected light is detected, the motor is turned on, and the motor’s vibration and acceleration information collected by the acceleration sensor are compared with the preset calibration vibration characteristic information to quickly and accurately determine the user’s The wearing state of the wearable device.

In an achievable embodiment, in order to improve the accuracy of the motor opening, and to avoid the occurrence of false opening caused by controlling the motor to start as long as the emitted light is received, please refer to FIG. 2, which is an embodiment of the application. A schematic flow diagram of motor control is provided, including:

S121. Compare the optical signal with a preset reference standard to obtain a comparison result;

The purpose of this step is to compare the light signal with a preset reference reference, so as to be able to accurately determine the qualified emitted light, and only qualified reflected light can control the motor to turn on.

Wherein, step S121 may include: judging whether the light signal intensity is within the preset light intensity range; if it is, it is determined that the reflected light is detected; if not, it is determined that the reflected light is not detected. It is understandable that the light sensor collects the light signal. In this embodiment, only when the intensity of the received light signal is within the preset light intensity range, can it be determined that the reflected light is detected, and then the motor can be controlled to turn on; otherwise, The motor is off. It can be seen that in this embodiment, the light intensity is used to determine whether the light reflected by the light sensor in a short distance is detected. Only the reflected light that meets the requirements can the step of controlling the motor opening be performed, which improves the accuracy of the motor opening. sex.

Wherein, step S121 may include: judging whether the distance corresponding to the light signal is less than the preset distance; if so, determining that the reflected light is detected; if not, determining that the reflected light is not detected. In this embodiment, the corresponding transmission distance is determined by the time information transmitted by the optical signal. Only when the distance is less than the preset threshold, it is determined that the reflected light is reflected, and then the step of controlling the motor opening can be performed, which improves the accuracy of the motor opening.

S122: If the comparison result is that reflected light is detected, control the motor to turn on;

S123: If the comparison result is that no reflected light is detected, enter the sleep mode.

When the reflected light is not detected, it enters the dormant state. At this time, the motor does not vibrate and no biological measurement is performed.

Based on the above technical solution, this embodiment compares the optical signal with a preset reference standard, and controls the motor to be turned on or kept in the closed state according to the comparison result, which improves the accuracy of motor turning on.

Based on the above embodiment, in order to make the acceleration data more effective and avoid the problem of the acceleration information error caused by the impact of the placement position of the wearable device on the vibration component, this embodiment provides another state detection method, please refer to Figure 3 , Figure 3 is another state detection method provided by an embodiment of this application, including:

S110: Obtain the light signal collected by the light sensor,

S131: Acquire reference acceleration information in a resting state collected by the acceleration sensor;

Among them, the reference acceleration information is the three-axis acceleration information acquired by the three-axis acceleration sensor in a static state, and it is used as a reference value.

S132: Acquire vibration acceleration information collected by the acceleration sensor when the motor is turned on;

S141: Determine actual acceleration information by using the reference acceleration information and the vibration acceleration information;

In this embodiment, the reference acceleration information is used to eliminate the impact of the wearable device on the vibration component when the wearable device is in different placement positions.

S142: Use actual acceleration information and preset calibration vibration characteristic information to match to determine the wearing state of the wearable device.

In this step, the actual acceleration information is used to determine the wearing state of the wearable device, and the result obtained is more accurate.

Further, when the preset calibration vibration characteristic information includes the first threshold and the second threshold, please refer to FIG. 4. FIG. 4 is a schematic diagram of a process for determining a wearing state according to an embodiment of the application, including:

S1421. Determine whether the actual acceleration information is greater than a first threshold;

S1422, if it is greater than the first threshold, determine that the wearing state is not worn, and turn off the physiological detection function;

When it is determined that the wearing state is not worn, turn off the physiological detection function, turn off the heart rate monitoring, blood oxygen analysis and other functions to save energy.

S1423: If it is not greater than the first threshold, determine whether the actual acceleration information is less than the second threshold;

Wherein, the first threshold is greater than the second threshold.

S1424. If it is less than the second threshold, determine that the wearing state is worn;

It is understandable that when the worn state is worn, the physiological detection function can be controlled to be turned on, and heart rate detection and blood oxygen analysis can be performed.

S1425: If it is not less than the second threshold, determine that the wearing state is irregular wearing.

Irregular wearing means that the wearable device is on the wrist, but it is too loose or too tight.

Further, after S1425, it also includes: sending prompt information to the prompt device; receiving a user's detection request, which is a request sent by the user using a preset operation after the user adjusts the wearing state according to the prompt information. It can be seen that by prompting the user to adjust the wear, so that the user can send a detection request to achieve physical health detection.

4. The three-axis acceleration sensor obtains the reference acceleration information in the static state, and serves as the reference reference value in step 6, which is used to eliminate the impact of the vibration component when the product is in different positions;

5. Turn on the motor and vibrate at a fixed frequency;
