Detailed Description
In order to make the features and advantages of the present application more comprehensible, embodiments accompanied with figures in the present application are described in detail below, wherein the embodiments are described only in some but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application as detailed in the accompanying claims.
In the description of the embodiments of the present application, it is to be understood that in the description of the present application, unless otherwise indicated, "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.
It can be understood that the temperature measurement method in the embodiment of the application is mainly applied to wearable devices, the wearable devices are in the form of portable accessories with partial computing function and capable of being connected with mobile phones and various terminals, the main product forms comprise watch types (including products such as watches and bracelets) supported by wrists, and the technical problems to be solved by the application are mainly concentrated on the wrist strap type products such as watches and bracelets, so that the wearable devices are expressed as wearable watches or wearable bracelets for convenience in description.
In the related art, a single temperature sensor is generally provided in the interior of the wearable device, and then after the user wears the wearable device through a wrist or the like, it may be necessary to measure the body surface temperature of the user wearing the wearable device. In a general temperature measurement scheme in the wearable device, a single temperature sensor is controlled to measure the temperature, and as the temperature sensor is mostly arranged at a position, close to a wearing part of a user, of the wearable device, the body surface temperature of the wearing user of the wearable device can be transmitted to the temperature sensor through the housing of the wearable device, so that the temperature, close to the position of the wearing part of the user, of the wearable device can be calculated according to measurement data obtained after the temperature measurement is carried out through the single temperature sensor, and the temperature can be used as the body surface temperature of the wearing user of the wearable device after being processed.
However, in the above related art, since the body surface temperature of the wearing user of the wearable device is calculated by only measuring the data through one temperature sensor, although the final measurement result is simply temperature-compensated by an algorithm in a partial measurement scheme to offset the temperature difference in the heat transfer process through the housing of the wearable device, the error after the temperature compensation is still larger, because the skin temperature measurement is affected by the factors such as the ambient temperature and the heat dissipation of the hardware itself, the calculated body surface temperature error of the wearing user of the wearable device is larger because the single temperature sensor measurement scheme cannot directly correct and compensate the temperature.
The embodiment of the application provides a temperature measurement scheme, wherein a first temperature sensor and a second temperature sensor are arranged in a wearable device, and because the arrangement positions of the first temperature sensor and the second temperature sensor in the wearable device are different, the conduction processes when the body surface temperature of a wearing user is conducted to the first temperature sensor and the second temperature sensor are different, when the body surface temperature of the wearing user is calculated through the first temperature sensor and the second temperature sensor, the scheme of calculating the body surface temperature of the wearing user through a single temperature sensor can be corrected, and the accuracy of the temperature measurement scheme of the wearable device is improved.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a wearable device according to an embodiment of the present application.
For convenience in describing the present application, taking the wearable device as a wearable watch or a wearable bracelet as an example, as shown in fig. 1, the wearable device 100 at least includes a housing 110, a main board 120, a first temperature sensor 130 and a second temperature sensor 140, materials of the housing 110 may not be limited, the housing 110 includes a bottom shell 111 and a top shell 112, shapes of the bottom shell 111 and the top shell 112 may not be limited, the bottom shell 111 and the top shell 112 may be mated, and the bottom shell 111 and the top shell 112 may be enclosed together through a fastening structure or a connecting device, so that the main board 120 is disposed in an accommodating space formed by enclosing the bottom shell 111 and the top shell 112, relevant electronic components may be disposed in the main board 120, and the first temperature sensor 130 and the second temperature sensor 140 may also be electrically connected with the electronic components in the main board 120, so as to ensure operation of the wearable device 100. Further, the first temperature sensor 130 is attached to the inner side of the bottom shell 111, the second temperature sensor 140 is disposed at a side of the first temperature sensor 130 away from the bottom shell 111, that is, the first temperature sensor 130 may be bonded to the inner side of the bottom shell 111, so that the first temperature sensor 130 may contact with the inner side of the bottom shell 111, and the second temperature sensor may be disposed in an accommodating space formed by enclosing the bottom shell 111 and the top shell 112 through a related connection device, so that the second temperature sensor 140 does not contact with the first temperature sensor 130, and is disposed at a side of the first temperature sensor 130 away from the bottom shell 111.
Referring to fig. 2, fig. 2 is a flow chart of a temperature measurement method according to an embodiment of the application.
As shown in fig. 2, the method for measuring temperature provided by the embodiment of the present application is applied to a wearable device in any embodiment of the present application, and the execution body in the embodiment of the present application may be the wearable device or a processor disposed in a main board of the wearable device, for convenience of description, the following description will take the execution body as an example of the processor in the main board of the wearable device, where the method includes:
s201, responding to a temperature measurement instruction, and acquiring a first temperature measured by a first temperature sensor and a second temperature measured by a second temperature sensor.
Because the temperature measurement method in the embodiment of the application is applied to the wearable equipment, and the wearable equipment generally has the functions of measuring the body surface temperature of a wearing user and displaying the body surface temperature in the wearable equipment, the user can freely set whether to start the temperature measurement function continuously performed in the wearable equipment or to temporarily start the temperature measurement function when the user needs.
When the wearable device is started and the wearable device detects that the temperature measuring function is started by a user, a processor in the wearable device can receive the temperature measuring instruction and respond to the temperature measuring instruction to control the first temperature sensor and the second temperature sensor to perform temperature measuring work, and after the first temperature sensor and the second temperature sensor perform temperature measuring work, the first temperature sensor can measure the first temperature of the temperature data acquisition part in the first temperature sensor and the second temperature sensor can measure the second temperature of the temperature data acquisition part in the second temperature sensor.
And S202, calculating the temperature of the outer side of the bottom shell based on the first temperature and the second temperature, and taking the temperature of the outer side of the bottom shell as the body surface temperature of a wearing user of the wearable device.
It can be known from the structure of the wearable device in fig. 1 that after the user wears the wearable device, the body surface temperature of the user is transmitted to the inner side of the bottom shell (the contact side between the bottom shell and the wearing part of the user) through the outer side of the bottom shell (the non-contact side between the bottom shell and the wearing part of the user), and the first temperature sensor is attached to the inner side of the bottom shell, so that the body surface temperature of the user is continuously conducted to the first temperature sensor through the inner side of the bottom shell, and then the first temperature measured by the first temperature sensor can be regarded as the temperature at which the body surface temperature of the user is conducted to the first temperature sensor through the bottom shell.
The body surface temperature of the wearing user is transmitted to the inner side of the bottom shell through the outer side of the bottom shell and then is continuously conducted to the first temperature sensor through the inner side of the bottom shell, and as the second temperature sensor is arranged on one side, far away from the bottom shell, of the first temperature sensor at intervals, the temperature on the first temperature sensor can be conducted to the second temperature sensor through a gas medium between the first temperature sensor and the second temperature sensor, and then the second temperature measured by the second temperature sensor can be regarded as the temperature at the position of the second temperature sensor through temperature conduction on the first temperature sensor.
The body surface temperature of the wearing user is conducted to the first temperature sensor through the outer side of the bottom shell and then is conducted to the second temperature sensor through the first temperature sensor, so that the first temperature source measured by the first temperature sensor and the second temperature source measured by the second temperature sensor are mainly from the body surface temperature of the wearing user, the temperature of the outer side of the bottom shell can be calculated firstly based on the first temperature and the second temperature, and then the temperature of the outer side of the bottom shell can be used as the body surface temperature of the wearing user of the wearable device.
According to the method, the body surface temperature of the wearing user is calculated and obtained, and meanwhile, two temperature conduction processes are considered, namely, the process that the body surface temperature of the wearing user is conducted to the first temperature sensor through the outer side of the bottom shell, and the process that the temperature on the first temperature sensor is conducted to the second temperature sensor are conducted.
It can be understood that in the embodiment of the application, two temperature sensors are used for correcting and compensating the temperature measurement process, but in practical application, two or more temperature sensors can be arranged, and each temperature sensor is arranged in the same heat transfer path.
In the embodiment of the application, at least two temperature sensors are arranged in the wearable device, the first temperature sensor is attached to the inner side of the bottom shell, and the second temperature sensor is arranged at one side of the first temperature sensor away from the bottom shell at intervals, so that the first temperature measured by the first temperature sensor and the second temperature measured by the second temperature sensor can be acquired first, then the temperature of the outer side of the bottom shell is calculated based on the first temperature and the second temperature, and the temperature of the outer side of the bottom shell is used as the body surface temperature of a wearing user of the wearable device. Because the setting positions of the first temperature sensor and the second temperature sensor in the wearable device are different, the conduction process when the body surface temperature of the wearing user is conducted to the first temperature sensor and the second temperature sensor is different, and when the body surface temperature of the wearing user is calculated through the first temperature sensor and the second temperature sensor, the scheme of calculating the body surface temperature of the wearing user through a single temperature sensor can be corrected, and the accuracy of the temperature measurement scheme of the wearable device is improved.
Referring to fig. 3, fig. 3 is a flow chart of a temperature measurement method according to another embodiment of the application.
As shown in fig. 3, the method includes:
s301, responding to a temperature measurement instruction, and acquiring a first temperature measured by a first temperature sensor and a second temperature measured by a second temperature sensor.
For step S301, please refer to the detailed description in step S201, and the detailed description is omitted here.
S302, acquiring a first relation between the temperature of the outer side of the bottom shell and the first temperature and the second temperature, and calculating the temperature of the outer side of the bottom shell based on the first relation, the first temperature and the second temperature.
In the embodiment of the application, in the process that the body surface temperature of the wearing user is conducted to the first temperature sensor through the outer side of the bottom shell, the first temperature sensor measures the first temperature, and the temperature on the first temperature sensor is conducted to the second temperature sensor, and the second temperature sensor measures the second temperature, namely, a first relation exists between the temperature of the outer side of the bottom shell and the first temperature and the second temperature.
Specifically, the body surface temperature of the wearing user is conducted to the first temperature sensor through the outer side of the bottom shell, at this time, the first temperature sensor measures the first temperature, and since the first temperature sensor is attached to the inner side of the bottom shell, that is, the temperature of the outer side of the bottom shell is directly conducted to the first temperature sensor through the solid medium of the bottom shell, the heat transfer process between the first temperature sensor and the bottom shell can be considered as a steady-state heat transfer process, wherein the steady-state heat transfer process refers to that the temperature of each point in the heat transfer system only changes along with the position and does not change along with time.
During steady state heat transfer, according to fourier's law (i.e. the amount of heat transfer per unit time through a given cross section is proportional to the rate of change of temperature in the direction perpendicular to that cross section, while the direction of heat transfer is opposite to the direction of temperature rise), the second relationship between the first temperature and the temperature outside the bottom shell is:
wherein q 1 A first heat flux density corresponding to a steady-state heat conduction process, wherein the heat flux density is heat transferred per unit time and unit area and is expressed in W/m 2 λ is a thermal conductivity coefficient corresponding to a steady-state thermal conduction process, where the unit is W/(m×deg.c), d is a vertical conduction distance between the first temperature sensor and the bottom shell, T is a temperature of an outer side of the bottom shell, and T 1 Is the first temperature.
Further, after the body surface temperature of the wearing user is conducted to the first temperature sensor through the outer side of the bottom shell, in the process that the temperature on the first temperature sensor conducts the second temperature sensor, the second temperature sensor measures the second temperature, because the second temperature sensor is arranged at a side, away from the bottom shell, of the first temperature sensor at intervals, that is, the first temperature on the first temperature sensor is conducted to the second temperature sensor through the gas medium between the first temperature sensor and the second temperature sensor, the heat transfer process between the second temperature sensor and the first temperature sensor can be considered as a steady-state heat convection process, wherein the steady-state heat convection process refers to a phenomenon of heat transfer occurring in the fluid (including gas) flowing process, that is, a process that the heat transfer is conducted by means of movement of fluid particles.
In the steady-state heat convection process, according to newton's law of cooling (i.e. the law followed when an object with a temperature higher than the surrounding environment transfers heat to the surrounding medium for gradual cooling, when there is a temperature difference between the surface of the object and the surrounding environment, the heat dissipated from the unit area per unit time is proportional to the temperature difference, and the proportionality coefficient is called the heat transfer coefficient), the third relationship between the second temperature and the first temperature is:
q 2 ＝h(T 1 -T 2 )；
wherein q 2 A second heat flow density corresponding to the steady-state heat convection process, h is a surface heat transfer coefficient corresponding to the steady-state heat convection process, T 2 Is the second temperature.
After obtaining the second relationship between the first temperature and the temperature of the outside of the bottom chassis and the third relationship between the second temperature and the first temperature, the first relationship between the temperature of the outside of the bottom chassis and the first temperature, the second temperature may be determined based on the second relationship and the third relationship.
Specifically, under the ideal condition that the influence of factors such as internal heat dissipation of hardware in the wearable device is not considered, on a vertical heat transfer path from the outer side of the bottom shell of the wearable device to the first temperature sensor and then to the second temperature sensor, the first heat flow density in the steady-state heat conduction process and the second heat flow density in the steady-state heat convection process are the same, so that the first heat flow density and the second heat flow density in the steady-state heat conduction process can be eliminated based on the second relation and the third relation, and the first relation between the temperature of the outer side of the bottom shell and the first temperature and the second temperature is obtained:
Then the hardware equipment test can be carried out in advance according to the wearable equipment, so that a plurality of groups of data about h and d are collected, and the data can be fitted by a least square methodThe value of the parameter, which can be used as a wearableThe device performs a constant value of the temperature measurement process.
In theory, the heat transfer needs to consider the direction, but since the heat transfer process between the first temperature sensor and the bottom shell and the heat transfer process between the second temperature sensor and the first temperature sensor are steady-state heat transfer processes, the heat transfer of the temperature only points to the second temperature sensor along one direction, namely, the outer side of the bottom shell, so that the sign of each parameter in the first relation is not affected. After the first relation between the temperature of the outer side of the bottom shell and the first temperature and the second temperature is obtained, the temperature of the outer side of the bottom shell can be calculated based on the first relation, the first temperature and the second temperature, namely, the temperature of the outer side of the bottom shell can be obtained by bringing the first temperature and the second temperature into the first relation, and then the body surface temperature of a wearing user of the wearable device is obtained.

As shown in fig. 4, on the basis of the structure of the wearable device 100 in fig. 1, a heat conductive material 150 may be further disposed between the first temperature sensor 130 and the inner side of the bottom case 111, wherein the heat conductive material 150 may have a heat conductive function such that the heat conductive material 150 may effectively transfer heat of the inner side of the bottom case 111 to the first temperature sensor 130; further, the heat conducting material 150 may also be a material with a specific shape or structure, so that the heat conducting material 150 has a soaking function, so that the heat conducting material 150 can effectively soak the skin heat contacted with the outside of the bottom shell 111, and further reduce the error between the first temperature measured by the first temperature sensor 130 and the temperature of the inside of the bottom shell 111, so that the accuracy of calculating the temperature of the outside of the bottom shell 111 based on the first temperature and the second temperature can be improved. The specific material type of the heat conductive material 150 may not be limited, and may be, for example, a thin graphite sheet.

After the first temperature sensor 130 and the second temperature sensor 140 are accommodated in the space inside the heat insulation cavity 160, the external ambient temperature of the wearable device 100 and the heat dissipation process of internal structures such as a hardware main board can be reduced, the influence on the heat transfer path (i.e., the heat transfer process between the first temperature sensor 130 and the bottom shell 111 and the heat transfer process between the second temperature sensor 140 and the first temperature sensor 130) in the wearable device 100 can be reduced, the effect of correcting and compensating the process of calculating the body surface temperature of the wearing user through the first temperature measured by the first temperature sensor 130 can be improved, and the accuracy of the temperature measurement scheme of the wearable device can be further improved.
