Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the technical solutions in the embodiments of the present invention will be 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 embodiments. The embodiments based on the invention should fall into the protection scope of the present invention.

It is to be understood that the wearable device according to embodiments of the present invention may be worn directly on the user or may be a portable electronic device integrated into the clothing or accessory of the user. Wearable equipment is not only a hardware equipment, can realize powerful intelligent function through software support and data interaction, high in the clouds interaction more, for example: the system has the functions of calculation, positioning and alarming, and can be connected with a mobile phone and various terminals. Wearable devices may include, but are not limited to, wrist-supported watches (such as watches, wrists, etc.), foot-supported shoes (such as shoes, socks, or other leg-worn products), head-supported glasses (such as glasses, helmets, headbands, etc.), and smart clothing, bags, crutches, accessories, etc. in a variety of non-mainstream product formats.

In order to solve the potential safety hazard, the invention utilizes the biological living body detection technology, and when the wearable equipment is worn on the hand of the user for charging, measures are taken correspondingly. The user group that this application embodiment was aimed at can be ordinary user, also can be children, and children's potential safety hazard is relatively speaking bigger some.

In the following, the technical solution of the present invention is further described by way of an embodiment, as shown in fig. 2, which is a schematic view of an embodiment of a charging method for a wearable device in an embodiment of the present invention, where the method is applied to a wearable device, and the method may include:

201. after detecting the head that charges and inserting, carry out the live body and detect, judge whether wearable equipment wears on user's arm.

In order to solve the problems in the background art, the application utilizes a living body detection module during charging, and also adds a Negative Temperature Coefficient (NTC) module for compatibility with individual differences, and a specific system block diagram is shown in fig. 4A and is a functional module schematic diagram of a wearable device:

in the illustration of fig. 3, the various modules function as follows:

a charging module: the charging module of the system can flexibly control the current according to the control instruction of the control unit.

Negative Temperature Coefficient (NTC) module: the control unit can read the blocking of the NTC and judge the temperature of the surface of the intelligent watch, so that the charging module is controlled to adjust the charging current. It is understood that NTC refers to a thermistor phenomenon and material having a negative temperature coefficient, in which resistance decreases exponentially with temperature rise. The material is a semiconductor ceramic formed by fully mixing, molding, sintering and other processes of two or more than two metal oxides of manganese, copper, silicon, cobalt, iron, nickel, zinc and the like, and can be made into a thermistor with a Negative Temperature Coefficient (NTC). The resistivity and material constant of the material vary with the material composition ratio, sintering atmosphere, sintering temperature and structural state. Non-oxide NTC thermistor materials typified by silicon carbide, tin selenide, tantalum nitride, and the like have also been developed.

A living body detection module: the function is to detect living organisms, such as a photo plethysmography (PPG module) which can detect heart rate and blood oxygen parameters of a human body, and thus detect whether a smart watch is worn on an arm. Optionally, the PPG module is typically placed on the back of the smart watch. The PPG technology is used for detecting the human body movement heart rate, and is an application of the infrared nondestructive detection technology in biomedicine. The heart rate is calculated from the obtained pulse waveform by utilizing a photoelectric sensor to detect the difference of the reflected light intensity after the absorption of blood and tissues of a human body, tracing the change of the volume of a blood vessel in a cardiac cycle.

It can be understood that, after the control unit detects the access of the charging head, the living body detection module can be started firstly to perform the living body detection, and whether the wearable device is worn on the arm of the user is judged.

Optionally, after detecting that the charging head is connected to the wearable device, performing living body detection to determine whether the wearable device is worn on an arm of the user may include: after the charging head is detected to be connected, determining that the wearable equipment is worn on the arm of the user through a photoplethysmography method if the pulse wave is detected; if the pulse wave is not detected, it is determined that the wearable device is not worn on the arm of the user. That is, it can be understood that if the wearable device detects a pulse wave, it is determined that the object to be measured is a living body, that is, it can be said that the wearable device is worn on the arm of the user, and if the wearable device does not detect a pulse wave, it is determined that the object to be measured is a non-living body, that is, it can be said that the wearable device is not worn on the arm of the user.

Optionally, after detecting that the charging head is connected to the wearable device, performing living body detection to determine whether the wearable device is worn on an arm of the user may include: after the charging head is detected to be connected, determining that the wearable equipment is worn on the arm of the user through a photoplethysmography method if the heart rate is detected; if the heart rate is not detected, it is determined that the wearable device is not worn on the arm of the user.

Optionally, after detecting that the charging head is connected to the charging device, performing living body detection to determine whether the wearable device is worn on an arm of a user may include: after the charging head is detected to be connected, determining that the wearable equipment is worn on the arm of the user through photoplethysmography if heart rate and blood oxygen parameters are detected; if the heart rate and the blood oxygen parameters are not detected, determining that the wearable device is not worn on the arm of the user.

Optionally, after the wearable device determines that the object to be measured is a living body, green light in the wearable device may be started to detect the heart rate of the living body. It will be appreciated that the wearable device uses green light to detect heart rate because the wearable device will use green light to obtain a signal that varies more than red light and that green light has a better resistance to ambient light than red light. Thus, wearable equipment adopts the signal-to-noise ratio that green light detected the rhythm of the heart than adopting the signal-to-noise ratio that red light detected the rhythm of the heart, and the signal-to-noise ratio is higher, and the external interference to wearable equipment detection rhythm of the heart is less, and the rhythm of the heart that this wearable equipment detected is more accurate.

Illustratively, assuming that the third preset frequency range is (20hz, 30hz), and the third frequency range is 25Hz, which is within (20hz, 10hz), the wearable device starts green light in the wearable device, and detects the heart rate of the living body at the frequency of 25 Hz.

Optionally, when the heart rate is within a preset heart rate range, the heart rate is recorded and stored. The preset heart rate range is an interval formed by a first preset heart rate threshold value and a second preset heart rate threshold value. Illustratively, the first preset heart rate threshold is less than the second preset heart rate threshold, and the preset heart rate range is generally set to (60 beats/min, 100 beats/min).

Optionally, when the heart rate is outside the preset heart rate range, outputting first prompt information. And the first prompt message is related suggestion provided by the wearable device for the user according to the heart rate.

Optionally, when the heart rate is outside the preset heart rate range, the wearable device outputs first prompt information, which may include: when the heart rate is less than or equal to a first preset heart rate threshold value, outputting first sub-prompt information; and outputting second sub-prompt information when the heart rate is greater than or equal to a second preset heart rate threshold value.

It can be understood that when the heart rate is less than or equal to the first preset heart rate threshold, the wearable device may determine that the living body is in the tachycardia state, and the output first sub-prompt information may prompt the user to detect the thyroid function of the user; when this rhythm of the heart more than or equal to second preset rhythm of the heart threshold value, this wearable equipment can judge that this live body is in bradycardia state, and the sub-suggestion information of second of output can be the reason that the suggestion user detected this live body rhythm of the heart and hang down to take corresponding measure.

Among them, there are three reasons for the heart rate being too low: the first is vagus nerve hyperactivity, where upon excitation, the distal ends of the vagus nerve release a substance called "acetylcholine", causing a hypopnea; the second is sick sinus syndrome, which is a sick heart showing the heart, and can be the heart rate hypo caused by coronary heart disease, cardiomyopathy and other diseases; the third is a severe atrioventricular block that causes a slow heartbeat, which in turn causes a low heart rate.

202. If so, performing one of the following: the method comprises the steps of not charging, executing a safe charging strategy, and outputting a prompt message, wherein the prompt message is used for prompting a user to take down the wearable equipment for charging.

If the control unit in the wearable device judges that the wearable device is worn on the arm of the user, charging is not carried out, or a prompt message is output, or charging is not carried out and a prompt message is output, or a safe charging strategy is executed; wherein, this prompt message is used for reminding the user to take off wearable equipment charges again.

Optionally, the wearable device executes a secure charging policy, which may include, but is not limited to, the following implementation manners:

(1) The wearable device is charged at a current less than a preset current threshold. It should be noted that, here, the wearable device is charged with a current smaller than the preset current threshold, that is, a current smaller than the normal charging current, so that the wearable temperature rise can be reduced to some extent.

(2) The wearable device is periodically charged at a current less than a preset current threshold. It should be noted that, here, the periodic charging is performed, and it can be understood as performing charging for 5 minutes, stopping charging for 1 minute, and so on, to ensure that the temperature of the wearable device is not too high.

(3) The wearable device is charged at a current less than a preset current threshold for a preset duration. For example, the wearable device may be charged at a current less than a preset current threshold for 20 minutes before automatically stopping the charging to ensure that the temperature of the wearable device is not too high.

Optionally, the method further includes: after the wearable device executes a safe charging strategy, if the temperature of the wearable device is detected to be greater than a first preset temperature threshold value, the current for charging is reduced or the charging is stopped. If the wearable device detects that the temperature of the wearable device is higher than a first preset temperature threshold value after executing a safe charging strategy, the wearable device can stop charging or reduce the charging current so as to ensure that the temperature of the wearable device is not too high, and therefore dangerous accidents occur.

Optionally, the method further includes: and if the temperature of the wearable equipment is detected to be greater than a first preset temperature threshold value and the charging electric quantity of the wearable equipment is greater than a preset electric quantity threshold value, reducing the charging current or stopping charging. If wearable equipment detects that the temperature of self is greater than a first preset temperature threshold value after executing the safe charging strategy, and the charging electric quantity of wearable equipment is greater than a preset electric quantity threshold value, the charging can be stopped or the charging current can be reduced without requiring full charge of the electric quantity, so that the temperature of the wearable equipment is not too high, and dangerous accidents occur.

Optionally, after the wearable device reduces the current for charging or stops charging, the method further includes: charging with a current less than the preset current threshold if it is detected that the temperature of the wearable device is less than a second temperature threshold, the second temperature threshold being less than the first temperature threshold. That is, after the wearable device reduces the current for charging or stops charging, if the temperature of the wearable device is detected to be lower than a certain threshold, the wearable device can be charged again, and the current for charging is still lower than the preset current threshold.

Optionally, the temperature of the wearable device is a surface temperature of the wearable device.

Exemplary, methods of determining a surface temperature of a wearable device: generally, the NTC resistor is built in the wearable device, and the surface temperature of the wearable device cannot be directly obtained. The temperature difference between the position of the NTC and the surface of the bottom shell of the wearable device can be found through a large number of tests. In practical application, the temperature difference can be compensated.

Illustratively, the safe charging policy refers to: the method comprises the steps of firstly charging with a small current, testing the current at the development stage to find a current which hardly causes temperature rise during charging of the intelligent watch, monitoring the NTC value in real time by a control unit in the charging process to determine the temperature of the surface of the watch, immediately reducing or stopping charging when the temperature exceeds a certain value (the value is normal temperature acceptable by a human body, such as 38 ℃), and restarting charging when the temperature is reduced to the certain value, such as 3 ℃ or 5 ℃ after temperature is returned.

203. If not, executing a common charging strategy.

If it is determined that the wearable device is not worn on the arm of the user, a normal charging strategy, i.e., a default normal charging strategy, is initiated.

In the embodiment of the application, after the charging head is detected to be connected, living body detection is carried out, and whether the wearable equipment is worn on the arm of a user is judged; if so, performing one of the following: the method comprises the steps of not charging, executing a safe charging strategy, and outputting a prompt message, wherein the prompt message is used for prompting a user to take down the wearable equipment for charging. When detecting that the user wears the wearable equipment on hand to charge, take corresponding measures, for not charging, or, carry out safe charging strategy, or, output prompt message to solve the potential safety hazard problem of charging.

As shown in fig. 3, a schematic diagram of another embodiment of a charging method for a wearable device in an embodiment of the present invention is applied to a wearable device, and the method may include:

301. the signal value received by the optical sensor is detected at a first frequency by an infrared detection means.

It should be noted that the optical sensor is used for receiving an infrared radiation signal value, where the infrared radiation signal value is an analog signal value, and the infrared radiation signal value may be an infrared light signal value reflected by an object to be measured; the optical sensor converts the analog signal value to obtain a digital signal value (signal value for short), and sends the digital signal value to the infrared detection device. The infrared detection device may be an infrared sensor, and the infrared detection device may receive the digital signal value transmitted by the optical sensor. Alternatively, the digital signal value may be a current value, and the unit of the current value is milliampere (mA).

Wherein, this infrared detection device and this optical sensor all are located wearable equipment, and concrete arrangement does not do not give concrete repeated description.

It is understood that the frequency is in hertz (abbreviated to Hz); the first frequency is within a first predetermined frequency range, which is acquired by the wearable device in a large amount of first experimental data. The first preset frequency range may be composed of a first preset frequency threshold and a second preset frequency threshold, and the first preset frequency threshold is smaller than the second preset frequency threshold.

It should be noted that, the value of the first frequency needs to satisfy the low power consumption function of the wearable device, so that when the wearable device is in a low power state, the wearable device starts the low power consumption function, and the infrared detection device can still detect the signal value received by the optical sensor at the first frequency, thereby determining whether the object to be detected exists in front of the wearable device.

For example, assuming that the first preset frequency range is (0hz, 10hz), and the first frequency is 5Hz, which is within (0hz, 10hz), at this time, the wearable device detects the signal value reflected by the object to be detected at the frequency of 5Hz through the infrared detection device.

302. And when the signal value is larger than a preset signal threshold value, determining that the object to be detected exists.

It should be noted that, after the wearable device receives the signal value sent by the optical sensor through the infrared detection device, the wearable device may compare the signal value with a preset signal threshold value to determine whether a blocking object exists in front of the wearable device, at this time, the blocking object is an object to be detected, and the object to be detected may be a living body or a non-living body, which is not specifically limited herein.

Wherein if the signal value is greater than a preset signal threshold, the wearable device may determine that an obstructing object is present in front; if the signal value is less than or equal to the preset signal threshold, the wearable device may determine that there is no obstructing object in front.

It can be understood that the preset signal threshold may be selected by collecting the wearable device in a large amount of second experimental data, that is, the preset signal threshold is set before the wearable device leaves the factory, and details are not described here.

For example, assuming that the preset signal threshold is 5mA, the wearable device passes through the infrared detection device, and the signal value sent by the receiving optical sensor is 6mA, where the 6mA is greater than 5mA, and at this time, the wearable device determines that the object to be measured exists in front of the wearable device.

Optionally, after step 102, the method may further include: and when the signal value is less than or equal to the preset signal threshold value, the wearable device is closed.

Optionally, the wearable device turns off the wearable device when the signal value is less than or equal to the preset signal threshold, which may include but is not limited to the following implementation manners:

implementation mode 1: when the signal value is less than or equal to the preset signal threshold value, the wearable device turns off photoplethysmography (PPG) on the wearable device through the acceleration accelerometer.

PPG can be an infrared nondestructive detection technique for detecting the heart rate of a living body. The wearable device closes the PPG on the wearable device, that is, the wearable device closes its infrared detection device, to reduce the power consumption of the wearable device.

Implementation mode 2: when the signal value is smaller than or equal to the preset signal threshold value, the wearable device outputs second prompt information and receives a first instruction input by a user, wherein the second prompt information is used for prompting that no object to be detected exists in front of the user; the wearable device is controlled to enter a standby state or a shutdown state according to the first instruction.

It can be understood that the first instruction is used to control the wearable device to enter a standby state or a power-off state, and the first instruction may be a voice instruction, may be a key instruction, and the key instruction may be an entity key instruction or a virtual key instruction, which is not limited specifically here.

Exemplarily, assuming that the preset signal threshold is 5mA, the wearable device receives a signal value sent by the optical sensor through the infrared detection device as 2mA, where the 2mA is smaller than 5mA, and at this time, the wearable device outputs second prompt information and receives a first instruction input by the user; the wearable device is controlled to enter a standby state according to the first instruction.

Optionally, the wearable device outputs the second prompt message, which may include but is not limited to the following implementation manners:

implementation mode 1: the wearable device outputs second prompt information in the form of voice.

It should be noted that the voice may be set before the wearable device leaves the factory, or may be set by the user according to the preference of the user, which is not specifically limited herein.

Implementation mode 2: the wearable device outputs second prompt information in the form of flashing lights.

It should be noted that the flashing light may be a single-color light, or may be an alternating flashing of colored lights, and is not limited herein.

Implementation mode 3: the wearable device outputs second prompt information in the form of vibration.

The vibration may be intermittent vibration or continuous vibration, and is not particularly limited herein.

It will be appreciated that whether in the form of voice, flashing lights, or vibration, is intended to facilitate the user in intuitively learning that the second topic is information. In particular, the implementation manners 1 to 3 may be combined with each other to form a new implementation manner, and the new implementation manner is also within the protection scope of the present invention, and will not be described in detail herein.

303. After detecting that the charging head is connected, performing living body detection on the object to be detected, and judging whether the wearable equipment is worn on the arm of the user.

304. If so, performing one of the following: the method comprises the steps of not charging, executing a safe charging strategy, and outputting a prompt message, wherein the prompt message is used for prompting a user to take down the wearable equipment for charging.

305. And if not, executing a common charging strategy.

It should be noted that, steps 303 to 305 may refer to steps 201 to 203 in the embodiment shown in fig. 2, and are not described herein again.

In the embodiment of the application, the signal value received by the optical sensor is detected at a first frequency by an infrared detection device; when the signal value is larger than a preset signal threshold value, determining that an object to be detected exists; after detecting that the charging head is connected, performing living body detection, and judging whether the wearable equipment is worn on the arm of the user; if so, performing one of the following: the method comprises the steps of not charging, executing a safe charging strategy, and outputting a prompt message, wherein the prompt message is used for prompting a user to take down the wearable equipment for charging. When detecting that the user wears the wearable equipment on hand to charge, take corresponding measures, for not charging, or, carry out safe charging strategy, or, output prompt message to solve the potential safety hazard problem of charging.

It can be understood that, by adopting the embodiment of the application, when a child uses the wearable device for charging, some safety accidents can not occur due to overhigh temperature of the watch.
