Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Most products only rely on heart rate monitoring module from the green light of taking or the reflection signal of infrared lamp, judge whether the product has worn, in case the product is placed on other objects, when the light of green light or infrared lamp can be reflected, the product thinks to be in wearing the state, still works, obtains inaccurate monitoring data, wastes the electric energy moreover. Based on the above technical problem, the present embodiment provides a state detection method, and referring to fig. 1 specifically, fig. 1 is a flowchart of a state detection method provided in the present embodiment, and specifically includes:
s110, acquiring an optical signal collected by an optical sensor;
specifically, a light sensor is arranged in the wearable device and used for collecting light signals.
S120, controlling a motor to be started when the reflected light is detected according to the optical signal;
the purpose of this step is to roughly measure the wearing situation and to determine the conditions under which the motor is turned on. When the reflected light is detected, the motor is controlled to be started when the reflected light is determined to be shielded. 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 light reflected from an obstacle after the light sensor emits light, wherein the obstacle may be a wrist of a user or other objects. And determining that the light reflection is detected according to the light signal, and controlling the motor to be started at the moment.
S130, acquiring acceleration information of the motor, which is acquired by an acceleration sensor;
after the motor is controlled to be turned on in step S120, the motor starts to vibrate, and at this time, the strength, the frequency, and the like of the vibration of the motor are not limited in this embodiment, and the user can customize the setting as long as the purpose of this embodiment can be achieved.
The wearable device in this embodiment is provided with an acceleration sensor for acquiring acceleration information after the motor vibrates. It is understood that when the user is not wearing the wearable device, the amplitude a1 of the motor vibration, the corresponding resulting acceleration information b 1; when the user successfully wears the wearable device, the motor vibration is greatly damped, the amplitude a2 of the motor vibration and corresponding obtained acceleration information b2 are obtained, wherein a1> a2 and b1> b 2.
And S140, matching the acceleration information with preset calibration vibration characteristic information to determine the wearing state of the wearable device.
In the step, the acceleration information is matched with the preset calibration vibration characteristic information, and the wearing state corresponding to the acceleration information is determined. For example, the calibration vibration characteristic information includes a wearing state C corresponding to C, D, E, F, C, a wearing state D corresponding to D, and a wearing state E corresponding to E, F. When the acceleration information is successfully matched with the C, determining that the wearing state of the wearable equipment is C; when the acceleration information is successfully matched with the D, determining that the wearing state of the wearable equipment is D; when the acceleration information is successfully matched with the E, determining that the wearing state of the wearable equipment is E; and when the acceleration information is successfully matched with the F, determining that the wearing state of the wearable device is F. The matching method is not limited in this embodiment, and may be within a range or may be a fixed value as long as the object of this embodiment can be achieved.
Further, the preset method for calibrating the vibration characteristic information comprises the following steps: when the wearable equipment is worn correctly, reading a calibration instruction; acquiring calibration acceleration information according to the calibration instruction; and determining standard vibration characteristic information according to the calibration acceleration information and preset standard acceleration information.
The preset standard acceleration information is information for all users, and it can be understood that, since the calibration acceleration information determined by each user is different, all users determine the standard vibration characteristic information corresponding to the user based on the preset standard acceleration information. For example, when the preset standard acceleration information is p and q, that is, the acceleration is greater than or equal to p, the wearing is not performed, the acceleration between p and q is not standard, and the wearing is performed when the acceleration is less than or equal to q; then when the user gets an unworn acceleration of p1 and a worn acceleration of q1 according to the first calibration command, 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 characteristics information. In the embodiment, the number of the accelerations and the mode of determining the standard vibration characteristic information are not limited, and the user can customize the setting.
Based on above-mentioned technical scheme, this embodiment utilizes light signal to confirm when detecting reflection light, opens the motor, utilizes the vibrations of motor and the acceleration information that acceleration sensor gathered, and with the calibration vibrations characteristic information that predetermines contrast, the wearing state of quick accurate definite user's wearable equipment.
In an implementation manner, in order to improve the accuracy of turning on the motor and avoid the occurrence of false turning-on caused by controlling the motor to turn on as long as the emitted light is received, please refer to fig. 2, where fig. 2 is a schematic flow chart of the motor control provided in the embodiment of the present application, and the schematic flow chart includes:
s121, comparing the optical signal with a preset reference standard to obtain a comparison result;
the purpose of this step is to compare the optical signal with a predetermined reference so as to be able to accurately determine whether the emitted light is qualified, and only the reflected light is qualified to control the motor to turn on.
Step S121 may include: judging whether the intensity of the optical signal is within a preset illumination intensity range; if yes, determining that the reflected light is detected; if not, determining that the reflected light is not detected. It can be understood that the light sensor collects the light signal, and in this embodiment, only if the intensity of the received light signal is within the preset illumination intensity range, it can be determined that the reflected light is detected, and the motor can be controlled to be turned on, otherwise, the motor is in the off state. It can be seen that, in this embodiment, whether light obtained by reflecting light emitted by the optical sensor in a short distance is detected is judged through the illumination intensity, and the step of controlling the motor to be turned on can be executed only if the light meets the requirement, so that the accuracy of turning on the motor is improved.
Step S121 may include: judging whether the distance corresponding to the optical signal is smaller than a preset distance or not; if yes, 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 according to the time information transmitted by the optical signal, and the step of controlling the motor to be turned on can be executed only when the distance is smaller than the preset threshold value and the reflected light is determined, so that the accuracy of turning on the motor is improved.
S122, if the comparison result is that the reflected light is detected, controlling the motor to be started;
and S123, if the comparison result shows that the reflected light is not detected, entering a sleep mode.
When the reflected light is not detected, the motor enters a dormant state, and the motor does not vibrate and does not perform biological measurement.
Based on the technical scheme, the light signal is compared with the preset reference, the motor is controlled to be turned on or kept in a turned-off state according to the comparison result, and the accuracy of turning on the motor is improved.
Based on the above embodiment, in order to make the acceleration data more effective and avoid the problem of error of the acceleration information caused by the influence of the placement position of the wearable device on the vibration component, the embodiment provides another state detection method, please refer to fig. 3, where fig. 3 is another state detection method provided by the embodiment of the present application, including:

S132, acquiring vibration acceleration information acquired by an acceleration sensor in a motor starting state;
s141, determining actual acceleration information by using the reference acceleration information and the vibration acceleration information;
in this embodiment, the influence of the wearable device on the vibration component when the wearable device is in different placement positions is eliminated by referring to the acceleration information.
And S142, matching the actual acceleration information with preset calibration vibration characteristic information to determine the wearing state of the wearable device.
The wearing state of the wearable equipment is determined by utilizing the actual acceleration information, and the obtained result is more accurate.
Further, when the preset calibration vibration characteristic information includes a first threshold and a second threshold, please refer to fig. 4, where fig. 4 is a schematic flow chart of determining the wearing state according to an embodiment of the present application, including:
s1421, judging whether the actual acceleration information is larger than a first threshold value;
s1422, if the wearing state is larger than the first threshold, determining that the wearing state is not worn, and closing the physiological detection function;
when the wearing state is determined to be not worn, the physiological detection function is closed, the functions of heart rate monitoring, blood oxygen analysis and the like are closed, and energy consumption is saved.
S1423, if the actual acceleration information is not greater than the first threshold, determining whether the actual acceleration information is less than a second threshold;
wherein the first threshold is greater than the second threshold.
S1424, if the value is smaller than the second threshold, determining that the wearing state is worn;
it can be understood that when the wearing state is the worn state, the physiological detection function can be controlled to be started, and heart rate detection, blood oxygen analysis and the like are performed.
And S1425, if the wearing state is not less than the second threshold, determining that the wearing state is not standard.
Where the wearing is not normal means that the wearable device is on the wrist, but too loose or too tight.
Further, after S1425, the method further includes: sending prompt information to a prompt device; and receiving a detection request of the user, wherein the detection request is sent by the user through a preset operation after the user adjusts the wearing state according to the prompt information.
