Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 invention.
At present, when a wearing state is detected through a heart rate sensor, if the heart rate sensor detects a proper heart rate value, it is indicated that wearable equipment is in the wearing state, and if the heart rate value is not detected, it is indicated that the wearable equipment is not worn.
Therefore, the embodiment of the invention discloses a wearing state detection method, a wearing state detection device, wearing state detection equipment and a storage medium, so that when the wearing state of wearable equipment is detected, the wearing state detection accuracy can be ensured, and the power consumption of the wearable equipment can be reduced.
Referring to fig. 1, an embodiment of the present invention provides a flow diagram of a wearing state detection method; as can be seen from fig. 1, the wearing state detection method includes:
s101, acquiring a first temperature value through a body surface temperature sensor of wearable equipment;
in this scheme, wearable equipment can be wearable equipment such as intelligent wrist-watch, intelligent bracelet, intelligent ring, and this scheme mainly uses intelligent wrist-watch as an example to explain this scheme. Body surface temperature sensor in this scheme is for setting up and is close to the human body side at wearable equipment, is used for detecting human body surface temperature's sensor, for example: if wearable equipment is the smart watch, this body surface temperature sensor is the sensor that is used for acquireing the wrist temperature for setting up at the back of smart watch, in this embodiment, can set up first temperature value as T1. In addition, when executing S101, the present solution may periodically execute S101 to detect the first temperature value at intervals of a predetermined time duration, and continue to execute the subsequent steps.
S102, judging whether the first temperature value is within a preset temperature range;
if not, executing S103; if yes, executing S104;
s103, judging that the wearable equipment is in an unworn state;
in particular, the body temperature of a human body may fluctuate physiologically according to factors such as age, day and night, sex, and emotion, but is substantially within the normal body temperature range, and therefore, in the present embodiment, the predetermined temperature range is set to represent the normal body temperature range of the human body, if the first temperature value T1 is not within the predetermined temperature range, it is determined that the wearable device is in an unworn state, if the first temperature value T1 is within the predetermined temperature range, it is determined that the wearable device is likely to be in a worn state, and it is determined that the wearable device is likely to be in a worn state, because the first temperature value is within the predetermined temperature range, there may be a case where the current ambient temperature is also within the predetermined temperature range, and at this time, it cannot be determined whether the first temperature value is within the predetermined temperature range because of the body temperature or because of the ambient temperature.
Such as: the preset temperature range is 36 degrees to 37 degrees, if the wearable device is not worn due to weather heat or the wearable device is placed on an object with a hot temperature, the body surface temperature sensor obtains the first temperature value which is 36 degrees, and if the wearable device is in a worn state, misdetection occurs.
S104, acquiring a second temperature value through an ambient temperature sensor of the wearable device;
in this scheme, ambient temperature sensor is the sensor that sets up in the not near human skin side of wearable equipment for detect ambient temperature, for example: if wearable equipment is intelligent wrist-watch, then this ambient temperature sensor can set up in the dial plate department of intelligent wrist-watch, is used for acquireing ambient temperature. In the present embodiment, the second temperature value acquired by the ambient temperature sensor is set to T2.
S105, judging whether the absolute value of the temperature difference between the first temperature value and the second temperature value exceeds a preset temperature threshold value; if not, executing S106; if yes, executing S107;
in this embodiment, the absolute value of the temperature difference between the first temperature value and the second temperature value may be understood as an absolute value | T2-T1| of a difference between the first temperature value and the second temperature value, where the predetermined temperature threshold is a preset maximum temperature change threshold Δ T, and if the absolute value of the temperature difference is greater than the preset temperature threshold, it indicates that the difference between the ambient temperature and the human body temperature is relatively large, and at this time, it indicates that the first temperature value is within a predetermined temperature range, but not due to the environment, but due to the human body temperature, it may be directly determined that the wearable device is in a worn state, and no heart rate detection is required, and by this means, on the basis of improving the detection accuracy, the number of heart rate detection times may be reduced, and the power consumption of the wearable device may be reduced; if the absolute value of the temperature difference is not greater than the preset temperature threshold, it indicates that the difference between the ambient temperature and the human body temperature is not large, and at this time, it indicates that the first temperature value is within the predetermined temperature range, which may be caused by the environment or the human body temperature, and therefore, S105 needs to be executed to perform the re-determination through the heart rate sensor.
It should be noted that, the specific value of the predetermined temperature threshold is not specifically limited herein, such as: the Δ T may be set to 0.2 or 0.5, and the setting may be modified according to actual circumstances.
S106, obtaining a heart rate value through a heart rate sensor of the wearable device, and determining the wearing state of the wearable device based on the heart rate value.
And S107, judging that the wearable device is in the worn state.
In the scheme, when the wearing state of the wearable device is determined based on the heart rate value, whether the heart rate value is within a preset heart rate value range or not can be specifically judged; if yes, the wearable device is judged to be in a worn state; if not, the wearable device is judged to be in an unworn state.
It should be noted that the predetermined heart rate value range is a normal heart rate value range of a human body, so before determining whether the heart rate value is within the predetermined heart rate value range, the present solution further needs to acquire user information of the wearable device, and determine the predetermined heart rate value range through the user information.
Specifically, the heart rate value in the present scheme is the number of heartbeats per minute in a resting state of a normal person, which may cause individual differences due to age, gender, or other physiological factors. Generally, the heart rate is faster for older people than for younger people, and faster for women than for men of the same age. Therefore, in this solution, the predetermined heart rate value range may be determined by user information of the wearable device, where the user information specifically is: user age, user gender, or a history of diseases that result in heart rate changes, etc.
In conclusion, in the scheme, when the wearing state of the wearable device is detected, if the first temperature value detected by the body surface temperature sensor is within the preset temperature range, the wearable device is likely to contact with a human body, and in order to improve the detection accuracy, the situation that the first temperature value is within the preset temperature range due to environmental factors and the absolute value of the temperature difference between the first temperature value and the second temperature value obtained by the environmental temperature sensor needs to be determined again is avoided; if the absolute value of the temperature difference does not exceed the preset temperature threshold, the environment temperature is close to the human body temperature, and the wearing state of the wearable equipment needs to be determined through the heart rate sensor, so that the accuracy of the wearing state detection is guaranteed; otherwise, the difference between the representative ambient temperature and the first temperature value is large, so that the phenomenon of false detection caused by environmental factors can not occur, the wearable device does not need to be determined again through the heart rate sensor, and the wearable device can be directly judged to be in a worn state; because temperature sensor's low power dissipation, consequently through this mode, can reduce wearable equipment's power consumption on the basis of guaranteeing the accuracy that wearing state detected.
Referring to fig. 2, an embodiment of the present invention provides another wearing state detection method flowchart diagram; it should be noted that, the same points of the inspection method described in this embodiment and the detection method described in the previous embodiment may be referred to each other, and are not described herein in detail.
As can be seen from fig. 2, the wearing state detection method includes:
s201, determining a movement change value of the wearable device; the movement change value is used for representing the position change degree of the wearable device within a preset time length;
s202, judging whether the movement change value is larger than a preset threshold value or not;
if not, executing S203; if yes, executing S204;
s203, acquiring a historical wearing state of the wearable device, and taking the historical wearing state as the current wearing state of the wearable device;
s204, acquiring a first temperature value through a body surface temperature sensor of the wearable device;
s205, judging whether the first temperature value is within a preset temperature range;
if not, executing S206; if yes, executing S207;
s206, judging that the wearable equipment is in an unworn state;
s207, acquiring a second temperature value through an environment temperature sensor of the wearable device;
s208, judging whether the absolute value of the temperature difference between the first temperature value and the second temperature value exceeds a preset temperature threshold value; if not, executing S209; if yes, executing S210;
s209, acquiring a heart rate value through a heart rate sensor of the wearable device, and determining the wearing state of the wearable device based on the heart rate value.
S210, judging that the wearable device is in a worn state.
Specifically, in this embodiment, before the first temperature value is acquired by the body surface temperature sensor of the wearable device, it may be further determined whether the wearing state needs to be detected by the temperature value and the heart rate value by moving the change value. The step S201 may be executed in real time after determining the wearing state of the wearable device, or may be executed periodically at intervals of a predetermined time length.
If it is detected through S201 that the movement variation value of the wearable device is small, it indicates that the wearable device is in a still state, and then the wearing state of the wearable device does not change, and at this time, it is not necessary to detect the wearing state again through the temperature value and the heart rate value, and at this time, the historical wearing state of the wearable device can be directly used as the current wearing state of the wearable device, such as: if the wearable device is detected to be in the unworn state last time and the change value of the movement change value of the wearable device is very small in the current time period detected last time, the wearable device is not moved greatly all the time, the wearing state is unchanged, and the wearable device is still in the unworn state; if the wearable device is detected to be in the worn state last time, but the change value of the movement change value of the wearable device is very small in the current time period detected last time, it indicates that the wearable device has not moved greatly, and the user may be in a deep sleep or almost still state, and the wearing state still does not change at this time and is still in the worn state.
If it is detected through S201 that the movement variation value of the wearable device is large, the test indicates that the wearable device is moved by a large margin, and the wearing state may change, at this time, S204 needs to be continuously executed, and the wearing state is detected again through the temperature value and the heart rate value.
It should be noted that, when determining the movement change value of the wearable device, the method and the device need to calculate the total acceleration value of the wearable device in real time, calculate the difference value between the maximum total acceleration value and the minimum total acceleration value within a predetermined time period, and take the difference value as the movement change value.
Specifically, in this embodiment, if the preset time period is set to 10s, the total acceleration value per second needs to be calculated in real time, and the total acceleration value is calculated by the following formula:
value(i)＝sqrt(x(i) 2 +y(i) 2 +z(i) 2 ) (ii) a Where i represents time, value (i) represents the total acceleration value for the i-th second, x (i) represents the acceleration value in the x-axis direction for the i-th second, y (i) represents the acceleration value in the y-axis direction for the i-th second, z (i) represents the acceleration value in the z-axis direction for the i-th second, and sqrt represents the square root calculation.
Then, from the 10s combined acceleration values, a maximum combined acceleration value max _ v ═ max (value) and a minimum combined acceleration value min _ v ═ min (value) are selected; calculating a difference diff between the maximum resultant acceleration value max _ v and the minimum resultant acceleration value min _ v, if the difference diff is greater than a preset Threshold, indicating that the position of the wearable device is changed, and continuing to execute S204 to detect the wearing state through the temperature value and the heart rate value; otherwise, it indicates that the wearable device has not moved greatly after the last detection wearing, and the detection is not needed again at this time. In this embodiment, specific values of the predetermined threshold are not specifically limited herein, such as: the Threshold can be set to 0.1 or 0.2, etc., and the setting can be modified according to actual situations.
In conclusion, before the body surface temperature sensor of the wearable device acquires the first temperature value, the wearing state can be detected by determining whether the body surface temperature sensor needs to pass through the temperature value and the heart rate value according to the movement change value. Through this mode, can avoid starting temperature sensor and rhythm of the heart sensor to detect when wearable equipment does not remove by a wide margin, further reduce opening of temperature sensor and rhythm of the heart sensor this moment, can further reduce the consumption of wearable equipment on the basis of guaranteeing the rate of accuracy.
