Please refer to FIG. 1 below. FIG. 1 is a flowchart of a temperature detection method provided by an embodiment of the present application.

Specific steps can include:

S101: Acquire the temperature of the outer surface of the device collected by the first temperature sensor;

Wherein, this embodiment can be applied to wearable devices such as smart bracelets, smart watches, AR (Augmented Reality, augmented reality) glasses, etc., and can also be applied to electronic devices such as mobile phones and computers connected to the wearable devices. In this embodiment, a first temperature sensor is provided on the device casing of the wearable device, and the first temperature sensor can collect the temperature of the outer surface of the device (ie, the outer side of the device casing) in contact with the external environment. As a feasible implementation manner, if the device casing is a casing made of a heat insulating material (such as plastic), and the first temperature sensor has a casing (the first temperature sensor with the casing can be waterproof and can be directly exposed to the external environment) ), the first temperature sensor in this embodiment may be embedded in the device casing and at least partially exposed to the external environment. As another feasible implementation manner, if the device casing is made of a thermally conductive material (such as copper, stainless steel, etc.), the first temperature sensor may be disposed inside the device and connected to the device casing through the thermally conductive material.

S102: Acquire the internal temperature of the device collected by the second temperature sensor;

Wherein, in this embodiment, a second temperature sensor may also be provided inside the device of the wearable device, and the second temperature sensor may measure the internal temperature of the device of the wearable device. As a feasible implementation manner, the above-mentioned second temperature sensor may be a contact temperature sensor. In this embodiment, the second temperature sensor may be set in a position inside the wearable device that is not easily affected by the ambient temperature, so as to obtain information on the working conditions of the wearable device at various times. The internal temperature of the device in mode. Specifically, in this embodiment, the second temperature sensor may be arranged on the main board of the wearable device, and the temperature of the main board may be used as the internal temperature of the device.

S103: Determine the ambient temperature according to the external surface temperature of the device and the internal temperature of the device.

Among them, the outer surface of the wearable device is in direct contact with the external environment, so the temperature of the outer surface of the device is affected by the ambient temperature, and the inner side of the device housing of the wearable device is the device internal environment of the wearable device, so the outer surface temperature of the device is also affected by the internal temperature of the device. Impact. According to the above analysis, the external surface temperature of the wearable device is determined by the ambient temperature and the internal temperature of the device, that is, there is a certain correspondence between the external surface temperature of the wearable device, the internal temperature of the device and the ambient temperature. The ambient temperature is calculated based on the external surface temperature of the device and the internal temperature of the device.

As a feasible implementation manner, this embodiment can also construct a temperature relationship table including multiple sets of known device outer surface temperatures, known device internal temperatures, and known ambient temperatures, and further establish the known device outer surface temperature and device internal temperature. Based on the temperature, query the temperature relation table to obtain the corresponding ambient temperature.

As a feasible implementation manner, in this embodiment, a temperature fitting function of the temperature of the external surface of the device, the temperature of the internal temperature of the device, and the ambient temperature can also be constructed, and the ambient temperature can be determined according to the temperature fitting function.

After the ambient temperature is determined, the current ambient temperature can be displayed through the display device, the current ambient temperature can be broadcast through the voice playback device, and corresponding prompt information can be generated when the ambient temperature is higher or lower than a certain critical value. If this embodiment is applied to a wearable device with a body temperature detection function, a correction operation based on the ambient temperature can be performed on the body surface temperature detected by the wearable device to obtain the real body temperature. Through the above body temperature detection method, the interference of ambient temperature on body temperature detection can be reduced, and the reliability of body temperature detection can be improved.

In this embodiment, a first temperature sensor is set on the device casing of the wearable device, and a second temperature sensor is also set inside the device of the wearable device. The first temperature sensor can collect the external surface temperature of the wearable device, and the second temperature sensor can collect The internal temperature of the wearable device. The external surface temperature of the wearable device is affected by both the ambient temperature and the self-heating of the wearable device. Therefore, the ambient temperature of the environment where the wearable device is located can be determined according to the internal temperature of the device and the external surface temperature of the device. It can be seen that this embodiment eliminates the interference of the wearable device's own heating on ambient temperature detection by acquiring the internal temperature of the device.

As a further introduction to the embodiment corresponding to FIG. 1 , before determining the ambient temperature in S103, there may also be an operation of constructing a temperature fitting function of the external surface temperature of the device, the internal temperature of the device, and the ambient temperature. N kinds of target ambient temperatures and M kinds of working modes are the outer surface temperature of the target device and the inner temperature of the target device, and then a temperature fitting function is generated according to the outer surface temperature of the target device, the inner temperature of the target device and the target ambient temperature. The above working modes may include any one or any combination of the following modes: (1) turn on the positioning function when the screen of the wearable device is off; (2) play music at 50% volume of the wearable device; (3) wear The device plays music at 100% volume; (4) the wearable device uses the call function. Of course, multiple application programs may be installed in the wearable device, and the above-mentioned M working modes may also include the wearable device running one or several application programs. N and M are natural numbers that can be any non-zero. Further, on the basis of the known temperature fitting function, the operation of determining the ambient temperature according to the device outer surface temperature and the device inner temperature may be: determining the ambient temperature corresponding to the device outer surface temperature and the device inner temperature according to the temperature fitting function.

The following describes the process of generating the temperature fitting function through a specific example: under the target ambient temperature T _amb1 , let the wearable device work in working mode 1, working mode 2, ..., working mode n respectively, and obtain the outer surface temperature T of the target device. _{out_m1_amb1} , T _{out_m2_amb1} , ..., T _{out_mn_amb1} and target device internal temperatures T _{in_m1_amb1} , T _{in_m2_amb1} , ..., T _{in_mn_amb1} . Under the target ambient temperature _Tamb2 , let the wearable device work in working mode 1, working mode 2, ..., working mode n respectively, and obtain the outer surface temperature T _{out_m1_amb2} , T _{out_m2_amb2} , ..., T _{out_mn_amb2} of the target device and the internal temperature T of the target device _{in_m1_amb2} , _{Tin_m2_amb2} , …, _{Tin_mn_amb2} . The above steps are repeated to obtain the combination of the external surface temperature T _out of the target device and the internal temperature T _in of the target device when the wearable device operates in different working modes under different target ambient temperatures. By collecting a large number of data of the target _ambient temperature _Tamb , the target device outer surface temperature T _out and the target device internal temperature T _in After fitting, the coefficients of the bivariate polynomial are obtained, so as to obtain the relational expression of the above three. Taking the binary quadratic polynomial as an example, T _amb =A(T _out ) ³ +B(T _out ) ² +C(T _out ) ² T _in +D T _out T _in +ET _in +FT _out +G, where A, B, C, D, E, F, G are compensation coefficients. Substitute the collected data of the target ambient temperature T _amb , the outer surface temperature T _out of the target device and the internal temperature T _in of the target device into the above polynomial, and the above compensation coefficients A, B, C, D, E can be obtained through data fitting processing, F, the value of G, so as to obtain the temperature fitting function of the target ambient temperature T _amb , the target device outer surface temperature T _out and the target device internal temperature T _in .

As a further introduction to the embodiment corresponding to FIG. 1 , after determining the ambient temperature in S103 , the user body surface temperature collected by the third temperature sensor may also be obtained, and the user body surface temperature may be corrected according to the ambient temperature to obtain the actual body temperature of the user. The above-mentioned third temperature sensor may be a non-contact sensor disposed on the wearable device, and a heat insulating layer is disposed outside the third temperature sensor to improve detection accuracy. Since the user's body surface temperature collected by the non-contact sensor is easily affected by the ambient temperature, the above method uses the ambient temperature to correct the user's body surface temperature on the basis of the known ambient temperature to obtain the user's real body temperature. In this embodiment, the temperature of the oral cavity, armpit or anus (rectum) can be used as the real body temperature of the user. For example, the process of using the ambient temperature to correct the user's body surface temperature to obtain the user's real body temperature. If the ambient temperature is T _amb , the user's body surface temperature is T1, and the user's real body temperature T2 is calculated as follows:

T2=T1+(T1-T _amb )*Q;

In the above formula, Q is the temperature correction weight. If the user's body surface temperature is 30 degrees Celsius and the ambient temperature is 10 degrees Celsius, the value of the temperature correction weight is 0.25. At this time, the user's real body temperature T2=32+(32-10)*0.25=37.5 Celsius.

Of course, different temperature measurement parts may have different temperature correction weights, for example, the temperatures of the arms and foreheads of the same human body are different. Therefore, in this embodiment, in the process of determining the actual body temperature of the user, the measurement part corresponding to the temperature of the user's body surface can be determined first; The temperature correction weight is determined according to the measurement site, and the user's body surface temperature is corrected according to the ambient temperature and the temperature correction weight to obtain the actual body temperature of the user. For example, the temperature correction weight of the forehead is 0.2, and the temperature correction weight of the back of the hand is 0.25. In an environment with an ambient temperature of 10 degrees Celsius, the temperature of user A's forehead and the temperature of the back of user B's hand are both 32 degrees Celsius. When using the above formula T2=T1+(T1-T _amb )*Q to calculate the user's real body temperature: user A's real body temperature T2=32+(32-10)*0.2=36.4 degrees Celsius, user B's real body temperature T2=32+ (32-10)*0.25=37.5 degrees Celsius.
