Detailed Description
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. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
An execution main body of the wearable device wearing detection method may be the wearable device wearing detection apparatus provided in the embodiment of the present application, or an electronic device integrated with the wearable device wearing detection apparatus, where the wearable device wearing detection apparatus may be implemented in a hardware or software manner. Wherein, wearable equipment can be like equipment such as intelligent glasses, intelligent helmet, intelligent bandeau, wearable smart mobile phone, wearable panel computer.
Referring to fig. 1, fig. 1 is a first flowchart illustrating a wearing detection method of a wearable device according to an embodiment of the present application. The specific process of the wearable detection method of the wearable device provided by the embodiment of the application can be as follows:
in 101, a detected value of the output voltage of the pyroelectric sensor is acquired.
With the development of technology, smart wearable devices are beginning to emerge and mature gradually. One type of smart wearable device that is common today includes head-mounted smart devices, such as smart glasses, smart helmets, smart headbands, and the like. Because these wearable devices have a high degree of intelligence and a powerful function, and consume a relatively large amount of power, it is very necessary to research how to reduce the power consumption of the wearable device as much as possible to prolong the endurance time of the wearable device. However, the scheme for reducing the power consumption of the wearable device in the related art cannot achieve a good effect of prolonging the endurance time. For example, in the prior art, a wearable device is detected by measuring a distance with an infrared sensor, so as to detect whether skin is close to the wearable device. This method also has many drawbacks, for example, the wearable device is easily occluded by different objects, and thus it is impossible to accurately determine whether the occlusion is caused by the wearable device being worn.
Among them, a thermoelectric sensor (TEG), also called a thermoelectric generator, is a device that can convert thermal energy into electric energy. Specifically, the core component of the pyroelectric sensor is a group of thermocouples which comprise an N-type semiconductor and a P-type semiconductor which are connected by a metal plate. The conductive connections at opposite ends of the P and N materials form a complete circuit. The pyroelectric sensor (TEG) operates when there is a thermal gradient in the thermocouple (i.e., the top is hotter than the bottom). In this case, the device generates a voltage and forms a current, thermal energy being converted into electrical energy according to the seebeck effect. The thermocouple groups are connected in series to form the thermoelectric module. If heat flows between the top and bottom of the module (creating a temperature gradient), a voltage can be generated and a current created. The pyroelectric sensor converts thermal energy (Q) to electrical energy (P) with an efficiency η. The larger the volume of the device is, the larger the heat Q is, and correspondingly, more electric energy P is generated. Similarly, the number of energy converters used is doubled, and since the thermal energy obtained is doubled, the electrical energy generated is naturally doubled. Regardless of the specific constraints of heat flow and system configuration, it is more convenient to use the absolute amount of electrical energy and heat consumed compared to the heat flow density (Q/a) using the heat energy generated per unit area (P/a). This is particularly convenient for pyroelectric sensors, since the device has good scalability: large scale devices can be easily formed by small modular arrays.
In the embodiment of the application, the thermoelectric sensor is arranged at a position on the wearable device, which is in contact with a human body, so that a temperature difference is generated between one surface of the thermoelectric sensor, which is in contact with the human body (corresponding to the top of the thermocouple), and the other surface of the thermoelectric sensor, which is not in contact with the human body (corresponding to the bottom of the thermocouple), at this time, the thermoelectric sensor works to generate an output voltage, and then the wearable device can acquire a detection value of the output voltage of the thermoelectric sensor.
At 102, it is determined whether the detection value is greater than a first preset threshold.
For example, after a detection value of the output voltage of the pyroelectric sensor is acquired, it is determined whether or not the detection value is larger than a first preset threshold.
In 103, it is determined that the wearable device is in a wearing state when the detection value is greater than a first preset threshold.
For example, when it is detected that the detected value of the output voltage of the pyroelectric sensor is greater than a first preset threshold value, it is determined that the wearable device is currently in the wearing state.
In the embodiment of the application, the wearable device judges whether the detection value is larger than a first preset threshold value or not by acquiring the detection value of the output voltage of the thermoelectric sensor, and when the detection value is larger than the first preset threshold value, the wearable device is determined to be in a wearing state. This scheme is through the thermoelectric sensor that can generate electricity, and the wearing state of current wearable equipment is judged with the produced voltage of the difference in temperature that ambient temperature formed when the thermoelectric sensor contacts the human body, can reduce wearable equipment's power consumption, prolongs its time of endurance.
The method according to the preceding embodiment is illustrated in further detail below by way of example.
Referring to fig. 2, fig. 2 is a second flowchart of a wearing detection method of a wearable device according to an embodiment of the present invention. The method comprises the following steps:
in 201, a detected value of the output voltage of the pyroelectric sensor is acquired.
In one embodiment, the thermoelectric sensor is disposed on the wearable device at a position where the thermoelectric sensor contacts with a human body, and a surface of the thermoelectric sensor contacting with the human body (corresponding to a top of the thermocouple) and another surface of the wearable device not contacting with the human body (corresponding to a bottom of the thermocouple) generate a temperature difference, and at this time, the thermoelectric sensor operates to generate an output voltage, and then the wearable device can obtain a detection value of the output voltage of the thermoelectric sensor.
At 202, it is determined whether the detection value is greater than a first preset threshold.
When the wearable device is worn by a human body, since the wearable device has a different structure and a different temperature at different parts of the human body, the area and the position of the wearable device in contact with the human body are different, and the output voltage generated by the pyroelectric sensor is also different, the first threshold is set for the characteristics of the wearable device.
In order to ensure that the wearable device can be accurately judged to be in the wearing state, the first threshold value can be set correspondingly according to the value of the output voltage generated by the thermoelectric sensor under the condition that the wearable device is in the wearing state. For example, a plurality of data of the output voltage generated by the pyroelectric sensor when the wearable device is in a wearing state may be measured, and an average value of the data may be taken as a first preset threshold. The median can also be taken as the first preset threshold.
In addition, since the ambient temperature is easily affected by seasons, geographical locations, and the like, for example, the temperature in winter is low, the temperature in summer is hot, the temperature difference between the indoor temperature and the outdoor temperature, and the temperature difference between the south and the north, the first preset threshold may be changed accordingly according to the change of the use environment of the wearable device.
For example, corresponding use modes can be set for use environments of the wearable device, the first preset threshold values are different in different use modes, the wearable device can manually adjust the corresponding use modes through a user, or the wearable device can automatically switch to the corresponding use modes according to the use environments by acquiring relevant information on the internet through a temperature sensor and a positioning system carried by the wearable device, so that the current use environments of the wearable device are determined, and the accuracy of judging whether the wearable device is in a wearing state or not is guaranteed. For example, when the difference between the current environment temperature and the human body temperature is detected to be small, the first preset threshold value can be correspondingly reduced; when the difference between the current environment temperature and the human body temperature is detected to be large, the first preset threshold value can be correspondingly increased. The specific setting of the first preset threshold value can be obtained through practical experiments.
In 203, it is determined that the wearable device is in a wearing state when the detection value is greater than a first preset threshold.
When the detection value of the thermoelectric sensor is detected to be larger than the first preset threshold, the thermoelectric sensor generates certain output voltage due to the fact that the body temperature and the ambient temperature of the user start to work, and therefore when the detection value of the output voltage is larger than the first preset threshold, the wearable device is in a wearing state.
It should be noted that, since the position where the wearable device makes contact with the human body is generally a structure on the wearable device that supports the human body, for example, a wrist band of a smart watch, a nose pad and a temple of smart glasses, or VR (Virtual Reality) glasses with a supporting point at the forehead or the chin. The pyroelectric sensor can be arranged at the positions, and the wearable device does not need to be provided with holes for placing corresponding devices, and only needs to be attached to a shell of the wearable device.
In 204, if the wearable device is currently in the off state, a power-on signal is triggered.
In one embodiment, the step of "triggering a power-on signal if the wearable device is currently in the power-off state" may include the steps of:
(1) the power-on circuit is powered on based on the output voltage of the thermoelectric sensor to trigger a power-on signal.
The starting circuit comprises a voltage comparison circuit. When the wearable device is in a wearing state, a temperature difference exists between one surface and the other surface of the thermoelectric sensor, an output voltage is generated, the output voltage is provided to a forward input end of the voltage comparison circuit, a reference voltage is arranged at a reverse input end of the voltage comparison circuit, so that high-level and low-level signals are generated between the output voltage of the thermoelectric sensor and the reference voltage, and the high-level signal is used as a starting signal to trigger the wearable device to start. In order to ensure that the wearable device can be triggered to be powered on when being worn, the reference voltage value is equal to a preset first threshold value.
In one embodiment, before powering on the power-on circuit based on the output voltage of the pyroelectric sensor, the method may further include the following steps:
(1) and judging whether the detection value is larger than a second preset threshold value, wherein the second preset threshold value is larger than or equal to the first preset threshold value.
(2) If so, the power-on circuit is powered on based on the output voltage of the thermoelectric sensor so as to trigger a power-on signal.
The above description has introduced that the pyroelectric sensor can convert thermal energy into electric energy, so that the electric energy generated by the pyroelectric sensor can be used to power up the startup circuit, which is used as a usable power source of the startup circuit to trigger the startup signal. In addition, the thermoelectric sensor can also be used as an electric energy source of a storage battery, and the storage battery supplies power to the starting circuit.
(3) If not, the power-on circuit is powered on based on the power module to trigger the power-on signal.
The power module generally comprises a main circuit, a control circuit, a detection circuit and an auxiliary power supply. And supplying power to the wearable equipment through a power module.
In an embodiment, when the wearable device is in the shutdown state, the power module may continuously supply power to the startup circuit, and maintain the operating state of the startup circuit to detect the output voltage of the thermoelectric sensor, so as to ensure that the wearable device triggers the startup signal when being in the wearing state.
In 205, if the wearable device is currently in the power-on state and the wearable device is not in the wearing state, the wearable device is controlled to execute a power-off operation.
When the wearable device is in a power-on state, the detection value of the output voltage of the thermoelectric sensor is also acquired, whether the detection value is larger than a first preset threshold value or not is judged, if the detection value is not larger than the first preset threshold value, the wearable device is determined not to be in a wearing state, and at the moment, the wearable device can be controlled to execute a power-off operation to shut down or to enter a power-saving mode in order to avoid unnecessary waste of power.
In an embodiment, before controlling the wearable device to perform the shutdown operation, the method may further include:
(1) and if the current wearable equipment is in the starting state and the wearable equipment is not in the wearing state, outputting shutdown prompt information.
In one embodiment, the relevant text prompt message may be displayed on a display screen to remind the user, or an audio output device of the wearable device, such as an electroacoustic transducer (e.g., a speaker), may be used to prompt the user with a voice to remind the user that the wearable device is about to perform a shutdown operation.
(2) And when the wearable device is not in the wearing state continuously within the preset duration after the shutdown prompt information is output, controlling the wearable device to execute shutdown operation.
The preset duration can be manually set, and the preset duration can also be set before the wearable device leaves a factory. For example, the preset time period may be 15 minutes, 30 minutes, 60 minutes, or the like.
For example, the display screen of the wearable device displays that "detect you do not use the device for a long time, in order to save power consumption, the device will automatically shut down after 2 minutes", "detect you do not use the device for a long time, in order to save power consumption, if no operation response exists within 2 minutes, the device will automatically shut down" or display: "detect you do not use this equipment for a long time, in order to save power consumption, will enter the power saving mode after 2 minutes" and "detect you do not use this equipment for a long time, in order to save power consumption, if there is no operation response within 2 minutes, this equipment will enter the power saving mode". Or voice broadcast is carried out by utilizing a loudspeaker of the wearable device to prompt the user.
In particular implementation, the present application is not limited by the execution sequence of the described steps, and some steps may be performed in other sequences or simultaneously without conflict.
Referring to fig. 3, fig. 3 is a scene schematic diagram of a wearing detection method of a wearable device according to an embodiment of the present application.
In this embodiment, the wearable device may be smart glasses, for example. A schematic diagram of the smart glasses may be as shown in fig. 3. Referring to fig. 3, the pyroelectric sensor may be disposed inside the nose pad, the nose bridge or the foot cover of the smart glasses 20, and only one side of the nose pad and one side of the foot cover are shown due to the limitation of the image viewing angle, it is understood that the other side of the nose pad and the other side of the foot cover may also be disposed with the pyroelectric sensor.
Wherein, the thermoelectric sensor is electrically connected with the starting circuit of the intelligent glasses.
In an embodiment, the power-on circuit may further include a processing chip, and the processing chip detects the output voltage generated by the pyroelectric sensor and controls the timing of triggering the power-on signal, for example, when the voltage comparison circuit in the power-on circuit generates a high level, the power-on signal is triggered.
The following description will be made in detail by the situations that the smart glasses are in the power-off state and the power-on state:
(1) in a first situation, when the smart glasses are in the off state:
for example, taking the example of disposing the pyroelectric sensor at the nose pad, one surface of the nose pad contacting the human body corresponds to one surface of the pyroelectric sensor, and the other surface of the nose pad not contacting the human body corresponds to the other surface of the pyroelectric sensor.
When the intelligent glasses are in the power-off state, the power-on circuit of the intelligent glasses is in the working state. If the current user wears the intelligent glasses, one surface of the thermoelectric sensor contacting with the human body and the other surface of the thermoelectric sensor not contacting with the human body can generate a temperature difference due to the difference between the temperature of the human body and the temperature of the use environment (under the general condition, the temperature of the human body is higher than the ambient temperature), the thermoelectric sensor works at the moment to generate output voltage, a starting circuit of the intelligent glasses can judge the current wearing state by detecting whether the detection value of the output voltage is larger than a first preset threshold value or not, and when the detection value of the output voltage is larger than the first preset threshold value, a voltage comparison circuit in the starting circuit generates a high-level signal, and the intelligent glasses are triggered to start through the high-level signal.
The first preset threshold may be an average value of multiple sets of data detected by the pyroelectric sensor when the smart glasses are worn, and the reference voltage is equal to the first preset threshold. For example, the preset first threshold may be 0.01V. If the detection value of the output voltage is larger than 0.01V, the intelligent glasses are currently in a wearing state, and at the moment, a starting signal is triggered. If the detection value of the output voltage is not greater than 0.01V, the intelligent glasses are not worn currently, and the intelligent glasses continue to be in a power-off state. The smart glasses may continuously detect a change in a detected value of the output voltage of the pyroelectric sensor, thereby confirming a wearing state of the smart glasses.
(2) The second situation, when the smart glasses are in the on state:
for example, also taking the example of disposing the pyroelectric sensor at the nose pad position, one surface of the nose pad contacting the human body corresponds to one surface of the pyroelectric sensor, and the other surface of the nose pad not contacting the human body corresponds to the other surface of the pyroelectric sensor.
If the current user wears the intelligent glasses, one surface of the thermoelectric sensor contacting with the human body and the other surface of the thermoelectric sensor not contacting with the human body can generate a temperature difference due to the difference between the temperature of the human body and the temperature of the use environment (under the general condition, the temperature of the human body is higher than the ambient temperature), the thermoelectric sensor works at the moment to generate output voltage, and the starting circuit of the intelligent glasses can judge the current wearing state by detecting whether the detection value of the output voltage is larger than a first preset threshold value. The first preset threshold may be an average value of multiple sets of data detected by the thermoelectric sensor when the smart glasses are worn. For example, the preset first threshold may be 0.01V. If the detection value of the output voltage is larger than 0.01V, the intelligent glasses are determined to be in a wearing state at present; if the detection value of the output voltage is not greater than 0.01V, the intelligent glasses are determined to be in an unworn state currently.
For another example, the smart glasses may continuously detect a change in the detected value of the output voltage of the pyroelectric sensor to confirm the wearing state of the smart glasses at present, and perform a corresponding operation according to the wearing state of the smart glasses at present. For example, to avoid unnecessary waste of power, the operation may be to control the smart glasses to turn off, or to control the smart glasses to enter a power saving mode. For another example, when the state that the smart glasses are not worn for more than 10 minutes, the smart glasses may be controlled to enter a power-off state, or the smart glasses may be controlled to enter a power saving mode. Or, when the state that the smart glasses are not worn for more than 30 minutes, the smart glasses may be controlled to enter a power-off state, or the smart glasses may be controlled to enter a power-saving mode.
In an embodiment, the user may be prompted by displaying a text prompt message through a display screen, or the user may be prompted by using an audio output device of the smart glasses, such as an electroacoustic transducer (e.g., a speaker), to prompt the user that the smart glasses are to perform a power-off operation or enter a power saving mode, and if the user does not want to turn off the smart glasses or enter the power saving mode, a corresponding blocking operation may be performed.
As can be seen from the above, in the wearable device wearing detection method provided in the embodiment of the present invention, the wearable device obtains the detection value of the output voltage of the pyroelectric sensor, determines whether the detection value is greater than a first preset threshold, and determines that the wearable device is in a wearing state when the detection value is greater than the first preset threshold. Compare only under the state of wearable equipment start among the prior art, just can carry out corresponding sensor and detect, this scheme is through the thermoelectric sensor that can generate electricity, no matter wearable equipment is in start state and shutdown state, the wearing state of current wearable equipment is judged to the produced voltage of the difference in temperature that forms with ambient temperature when both can both contact the human body through thermoelectric sensor, not only can reduce wearable equipment's power consumption, prolongs its duration, can also trigger the start signal through wearable equipment's wearing state. In addition, because do not need to carry out the trompil in order to place corresponding device on wearable equipment, only need paste wearable equipment casing can, can not destroy the uniformity of outward appearance, structural compatibility is stronger.
In an embodiment, a wearing detection device of the wearable device is also provided.

In an embodiment, the wearing detection apparatus 300 of the wearable device may further include a control module 305, configured to control the wearable device to perform a shutdown operation if the wearable device is currently in a power-on state and the wearable device is not in the wearing state.

This scheme is through the thermoelectric sensor that can generate electricity, and the wearing state of current wearable equipment is judged with the produced voltage of the difference in temperature that ambient temperature formed when the thermoelectric sensor contacts the human body, can reduce wearable equipment's power consumption, prolongs its time of endurance.
