[0028] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0029] With the development of the Internet of Everything, controller and sensor products are developing towards functional diversification and device densification. To achieve real-time display of temperature sensor information for users and direct execution of control based on temperature information, heat-generating devices such as screens, main control chips, power supplies, and relays need to be integrated inside the product. The existence of heat-generating devices makes the internal temperature of the product higher than the ambient temperature. The temperature measured by arranging a temperature sensor at any position inside the product is higher than the ambient temperature of the product, which makes it impossible for the sensor to accurately detect the ambient temperature.

[0030] In the related art, in response to the problem of temperature detection deviation, a solution of using an algorithm to correct the data measured by the temperature sensor has also been proposed. The temperature correction value is generally pre-tested in a laboratory environment, and there are certain differences between the actual installation environment of the device and the standard environment of the laboratory. Therefore, the temperature correction value preset before the device leaves the factory will not be able to adapt to the actual installation scenario of the device. Using the temperature correction value preset before the device leaves the factory to correct the detected ambient temperature will cause a secondary deviation between the ambient temperature detected by the device and the actual ambient temperature; at the same time, as the device is used over time, the heat generation power consumption of the device may drift compared with the power consumption before leaving the factory. Using this temperature correction value to correct the detected ambient temperature will further lead to low accuracy of the ambient temperature detected by the device.

[0031] To alleviate the above problems, the inventors of the present application proposed an environmental temperature acquisition method, device, equipment, and storage medium provided by the present application. By obtaining the current temperature calibration value, which is used to calibrate the temperature of the device using the operating heat of the device; determining the target temperature calibration value according to the current temperature calibration value and the preset temperature calibration value; obtaining the current actual temperature value detected by the device; and obtaining the actual environmental temperature value according to the target temperature calibration value and the current actual temperature value. Therefore, by adopting the above method of the present application, the current temperature calibration value of the device is obtained, the target temperature calibration value is determined according to the current temperature calibration value and the preset temperature calibration value, and the current actual temperature detected by the device is corrected using the target temperature calibration value, eliminating the influence of the secondary deviation between the detected environmental temperature and the actual environmental temperature caused by different installation environments and device heat dissipation power drift, enabling the device to automatically adapt to different installation environments and different heat dissipation power scenarios to obtain a more accurate environmental temperature in the environment where the device is located.

[0032] The following will specifically describe the embodiments of the present application with reference to the drawings.

[0033] Please refer to Figure 1 , an environmental temperature acquisition method provided by an embodiment of the present application can be applied to an electronic device with a temperature sensor. The steps and processes on the device side are described in this embodiment. The method includes steps S110 to S140.

[0034] Step S110: Obtain the current temperature calibration value, which is used to calibrate the temperature of the device using the operating heat of the device.

[0035] In an embodiment of the present application, the manner of obtaining the current temperature calibration value may be to obtain a first target temperature value, which is the temperature value obtained according to multiple first temperatures detected by the device within a first target time period, and the first target time period is the time period when the device is in an idle state; obtain the reference environmental temperature value detected by the device at the target reference time, and the target reference time is the time when the device is turned on or awakened and starts to work; obtain a second target temperature value, which is the temperature value obtained according to multiple second temperatures detected by the device within a second target time period, and the second target time period is the time period when the device is in a working state; and obtain the current temperature calibration value according to the first target temperature value, the reference environmental temperature value, and the second target temperature value.

[0036] In some embodiments, before obtaining the first target temperature value, the processor in the device determines whether multiple first temperatures detected by the device within the first target time period meet a first preset condition; if the multiple first temperatures meet the first preset condition, then obtain the first target temperature value.

[0037] Specifically, the way to determine whether multiple first temperatures detected by the device within the first target time period meet the first preset condition can be to determine whether the absolute value of the difference between the maximum temperature value and the minimum temperature value among the multiple first temperatures is less than or equal to the first preset temperature difference; if the absolute value of the difference between the maximum temperature value and the minimum temperature value among the multiple first temperatures is less than or equal to the first preset temperature difference, then the multiple first temperatures meet the first preset condition.

[0038] In some other embodiments, the way to determine whether multiple first temperatures detected by the device within the first target time period meet the first preset condition can also be to determine whether the ambient temperature of the environment where the device is located is stable according to the multiple first temperatures detected within the first target time period; if it is stable, then obtain the first target temperature value according to the multiple first temperatures detected within the first target time period.

[0039] Among them, to determine whether the ambient temperature of the environment where the device is located is stable according to the multiple first temperatures detected within the first target time period, it can be by calculating the variance of the multiple first temperatures. If the variance is less than the preset variance, then the ambient temperature of the environment where the device is located is stable; it can also be by calculating the standard deviation of the multiple first temperatures. If the standard deviation is less than the preset standard deviation, then the ambient temperature of the environment where the device is located is stable; it can also be by calculating the average difference of the multiple first temperatures. If the average difference is less than the preset average difference, then the ambient temperature of the environment where the device is located is stable; it can also be by other ways to determine whether the ambient temperature of the environment where the device is located is stable. Specifically, the way for the device to determine whether the ambient temperature of the environment where it is located is stable is not limited herein.

[0040] In the embodiments of the present application, the first preset temperature difference can be pre-stored in the device, or obtained from other associated devices through a serial peripheral interface (SPI) or wireless communication technology, or obtained from an associated cloud through wireless communication technology; the specific value of the first preset temperature difference can be obtained through third-party experimental data, or an appropriate value can be selected according to the actual accuracy requirements of the device.

[0041] In some embodiments, if it is determined according to the multiple first temperatures detected within the first target time period that the ambient temperature of the environment where the device is located is unstable, that is, the multiple first temperatures detected by the device within the first target time period do not meet the first preset condition, the device can re-determine a first target time period, obtain the multiple first temperatures detected by the device within this first target time period, and obtain the first target temperature value according to the multiple first temperatures that meet the first preset condition.

[0042] Among them, the processor in the device obtaining multiple first temperatures detected by the device within the first target time period may be obtaining multiple first temperatures continuously or at intervals detected by a temperature sensor in the device during a continuous time period when the device is in an idle state. Among them, the first target time period may be a continuous time period such as 0.5h, 1h, 1.5h, etc. when the device is in an idle state. The time period when the device is in an idle state can be understood as the time period when the device is in a state where the user does not operate the device or the device does not execute control tasks. Specifically, if the device is in an idle state, that is, the device only performs the operation of detecting the ambient temperature, and at this time, there is no user operating the device, such as the user viewing historical ambient temperature data on the device, etc., or there is no linkage with other devices, that is, no control tasks are executed, such as controlling air conditioners, fresh air, etc.

[0043] After the processor in the device obtains multiple first temperatures detected by the device within the first target time period and determines that the multiple first temperatures detected by the device within the first target time period meet the first preset condition, a first target temperature value is obtained according to the multiple first temperatures detected within the first target time period.

[0044] Optionally, obtaining the first target temperature value according to the multiple first temperatures detected within the first target time period may be obtaining the temperature mean of the multiple first temperatures detected within the first target time period and using the obtained temperature mean as the first target temperature value to obtain the first target temperature value; it may also be obtaining the median of the multiple first temperatures detected within the first target time period and using the obtained median as the first target temperature value to obtain the first target temperature value; it may also be obtaining the mode, arithmetic mean, weighted mean, geometric mean, etc. of the multiple first temperatures detected within the first target time period to obtain the first target temperature value.

[0045] In the embodiments of the present application, first, it is determined whether the multiple first temperatures detected by the device within the first target time period meet the first preset condition. If they meet, then a first target temperature value is obtained according to the multiple first temperatures detected by the device within the first target time period. It is necessary to ensure that the ambient temperature of the current environment is stable when the device is in an idle state, so as to avoid errors in the current temperature calibration value finally obtained through the first target temperature value, and to obtain a more accurate ambient temperature in the environment where the device is located.

[0046] In the embodiments of the present application, a reference ambient temperature value detected by the device at the target reference time is obtained, and the target reference time is the time when the device is turned on or awakened and starts to work.

[0047] It should be noted that the temperature detected by the temperature sensor and algorithm judgment can only be obtained when the device starts to work.

[0048] Specifically, the target reference time can be the moment when the device is in the off state or in the low-power mode operating state and then is turned on or awakened to start working. Since the device has just started working and the heat generated by the heating components inside the device can be ignored, the ambient temperature value detected by the device at this time is closest to the actual ambient temperature value, and this detected ambient temperature value can be used as the reference ambient temperature value.

[0049] In some embodiments, the target reference time can also be the moment when the device is restarted or reawakened to start working after being turned off or operating in the low-power mode for a preset duration.

[0050] Among them, the value of the preset duration mainly depends on the position of the temperature sensor from the heat source, the weight and material of the device, etc., and can be obtained through third-party experimental data. After the device is turned off or operates in the low-power mode for the preset duration, the temperature of the temperature sensor of the device can drop to the ambient temperature, and at this time, the ambient temperature value detected by the temperature sensor is closest to the actual ambient temperature value. It should be understood that the value of the preset duration should satisfy that after the device is turned off for the preset duration, the ambient temperature value that can be detected by the temperature sensor of the device is closest to the actual ambient temperature value.

[0051] In some other embodiments, the target reference time can also be the moment when the device is restarted or reawakened to start working after being turned off or operating in the low-power mode for a preset duration after the device obtains the first target temperature value, so as to eliminate the influence of the heat generated by the heating components inside the device on the measurement of the ambient temperature by the temperature sensor.

[0052] Specifically, please refer to Figure 2 , in some embodiments, the technical solution for restarting the device to start working after the device is turned off for a preset duration is as Figure 2 shown. This solution mainly includes the main control 10, power supply 20, MCU (Micro Control Unit) 30, and external timer 40 of the device. Specifically, the main control 10 can be connected to the MCU (Micro Control Unit) 30 through interfaces such as UART (Universal Asynchronous Receiver-Transmitter) interface, SPI (Serial Peripheral Interface), COM (Serial Port Connection), or GPIO (General-Purpose Input / Output); the MCU (Micro Control Unit) 30 can be connected to the power switch of the main control 10 through interfaces such as UART (Universal Asynchronous Receiver-Transmitter) interface, SPI (Serial Peripheral Interface), COM (Serial Port Connection), or GPIO (General-Purpose Input / Output), and by controlling the power switch of the main control 10, the device can be restarted to start working after being turned off for the preset duration.

[0053] Among them, the control process of the technical solution for restarting the device to work after the device is turned off for a preset duration can be as follows: When the main control 10 is turned on and the timer 40 is cleared, when the device is in an idle state (that is, when the user does not operate the device and the device does not execute tasks), the main control 10 sends an instruction to turn off the power supply 20 to the MCU (microcontroller unit) 30 through UART. After receiving the instruction to turn off the power supply 20, the MCU (microcontroller unit) 30 turns on the power switch of the main control 10 to turn off the power supply 20 and turns on the timer 40 to start timing. At this time, the operation of turning off the device is completed; after the timer 40 reaches the preset duration, it starts to be cleared, and at the same time, the MCU (microcontroller unit) 30 controls the power switch of the main control 10 to close to turn on the power supply 20, so that the device starts to work. It should be noted that when the device starts to work, the ambient temperature detected by the temperature sensor can be obtained and algorithm judgment calculations can be performed.

[0054] In some embodiments, the target reference time can be the time when the device is restarted to work after being switched to the low-power state for a preset duration. Among them, the technical solution for restarting the device to work after the device is switched to the low-power state for a preset duration can be to utilize the low-power mode built into the main control chip of the device and set an interrupt source through the RTC (real-time clock chip) to make the main control chip core of the device enter the sleep state, that is, the low-power state. At this time, the power consumption required for the main chip to operate is extremely low, and the temperature sensor of the device can be cooled to the ambient temperature; after the device remains in the sleep state for the duration of the interrupt source (that is, the preset duration), the main program is restored under the guidance of the main control chip core, so that the device starts to work, that is, after the device is switched to the low-power state for a preset duration, the device is restarted.

[0055] In some embodiments, in a scenario where the device has a low requirement for the detection accuracy of the ambient temperature, the ambient temperature value detected during the warm-up window period when the device is powered on for the first time can be directly obtained, and the detected ambient temperature value can be used as the reference ambient temperature value. This is because during the warm-up window period when the device is powered on for the first time, the ambient temperature value detected by the device is less affected by the heat generated by the heating components, and the detected ambient temperature value is closer to the actual ambient temperature value.

[0056] In some embodiments, before obtaining the second target temperature value, the processor in the device determines whether a plurality of second temperatures detected by the device within the second target time period meet a second preset condition; if the plurality of second temperatures meet the second preset condition, the second target temperature value is obtained.

[0057] Specifically, the method for determining whether multiple second temperatures detected by the device within the second target time period meet the second preset condition can be to determine whether the absolute value of the difference between the maximum temperature value and the minimum temperature value among the multiple second temperatures is less than or equal to the second preset temperature difference; if the absolute value of the difference between the maximum temperature value and the minimum temperature value among the multiple second temperatures is less than or equal to the second preset temperature difference, then the multiple second temperatures meet the second preset condition.

[0058] In some other embodiments, the method for determining whether multiple second temperatures detected by the device within the second target time period meet the second preset condition can also be to determine whether the ambient temperature of the environment where the device is located is stable according to the multiple second temperatures detected within the second target time period; if it is stable, then according to the multiple second temperatures detected within the second target time period, a second target temperature value is obtained.

[0059] Among them, determining whether the ambient temperature of the environment where the device is located is stable according to the multiple second temperatures detected within the second target time period can be by calculating the variance of the multiple second temperatures. If the variance is less than the preset variance, then the ambient temperature of the environment where the device is located is stable; it can also be by calculating the standard deviation of the multiple second temperatures. If the standard deviation is less than the preset standard deviation, then the ambient temperature of the environment where the device is located is stable; it can also be by calculating the variance of the multiple second temperatures. If the average difference is less than the preset average difference, then the standard deviation of the ambient temperature of the environment where the device is located is stable; it can also be by other methods to determine whether the ambient temperature of the environment where the device is located is stable. Specifically, the method for the device to determine whether the ambient temperature of the environment where it is located is stable is not limited herein.

[0060] In the embodiments of the present application, the second preset temperature difference can be pre-stored in the device, or obtained from other associated devices through a serial peripheral interface (SPI) or wireless communication technology, or obtained from an associated cloud through wireless communication technology; the specific value of the second preset temperature difference can be obtained through third-party experimental data, or an appropriate value can be selected according to the actual accuracy requirements of the device. Among them, the first preset temperature difference and the second preset temperature difference can be the same or different.

[0061] In some embodiments, if it is determined according to the multiple second temperatures within the second target time period that the ambient temperature of the environment where the device is located is unstable, that is, the multiple second temperatures detected by the device within the second target time period do not meet the second preset condition, the device can re-determine a second target time period, obtain the multiple second temperatures detected by the device within this second target time period, and obtain the second target temperature value according to the multiple first temperatures that meet the first preset condition.

[0062] Among them, the processor in the device obtaining multiple second temperatures detected by the device within the second target time period may be obtaining multiple second temperatures continuously or intermittently detected by a temperature sensor in the device during a continuous time period when the device is in a working state. Among them, the second target time period may be a continuous time period such as 0.5h, 1h, 1.5h, etc. when the device is in a working state. The time period when the device is in a working state can be understood as the time period when the device is under user operation or the device is performing a control task. Specifically, if the device is in a working state, the device is not only detecting the ambient temperature at this time, but there is also user operation on the device, such as viewing historical ambient temperature data on the device, etc., or the device is also linked with other devices, that is, performing a control task, such as controlling an air conditioner, fresh air, etc., or there is user operation on the device and the device is also linked with other devices, etc.

[0063] After the processor in the device obtains multiple second temperatures detected by the device within the second target time period and determines that the multiple second temperatures detected by the device within the second target time period meet the second preset condition, the second target temperature value is obtained according to the multiple second temperatures detected within the second target time period.

[0064] Optionally, obtaining the second target temperature value according to the multiple second temperatures detected within the second target time period may be calculating the temperature mean of the multiple second temperatures within the second target time period and using the obtained temperature mean as the second target temperature value to obtain the second target temperature value; it may also be calculating the median of the multiple second temperatures within the second target time period and using the obtained median as the second target temperature value to obtain the second target temperature value; it may also be calculating the mode, arithmetic mean, weighted average, geometric mean, etc. of the multiple second temperatures detected within the second target time period to obtain the second target temperature value.

[0065] In the embodiment of the present application, first determine whether the multiple second temperatures detected by the device within the second target time period meet the second preset condition. If so, then obtain the second target temperature value according to the multiple second temperatures detected by the device within the second target time period. It is necessary to ensure that the ambient temperature of the current environment is stable when the device is in a working state, so as to avoid errors in the current temperature calibration value finally obtained through the second target temperature value, and to obtain a more accurate ambient temperature in the environment where the device is located.

[0066] In the embodiment of the present application, obtaining the current temperature calibration value according to the first target temperature value, the reference ambient temperature value, and the second target temperature value may be calculating the mean of the first difference and the second difference and using the obtained mean as the current temperature calibration value of the device; where the first difference is the difference between the first target temperature value and the reference ambient temperature value, and the second difference is the difference between the second target temperature value and the reference ambient temperature value.

[0067] In some embodiments, before calculating the average value of the first difference and the second difference, it is determined whether the absolute value of the difference between the first difference and the second difference is less than or equal to a third preset difference; if the absolute value of the difference between the first difference and the second difference is less than or equal to the third preset difference, the average value of the first difference and the second difference is calculated, and the obtained average value is used as the current temperature calibration value of the device.

[0068] In the embodiments of the present application, the third preset temperature difference can be pre-stored in the device, or obtained from other associated devices through a serial peripheral interface (SPI) or wireless communication technology, or obtained from an associated cloud through wireless communication technology; the specific value of the third preset temperature difference can be obtained through third-party experimental data or an appropriate value can be selected according to the actual accuracy requirements of the device. Among them, the third preset difference may be the same as or different from the first preset difference and the second preset difference, and no specific limitation is made here.

[0069] Taking an embodiment provided by the present application as an example for illustration, the specific calculation process for obtaining the current temperature calibration value is as follows:

[0070] Please refer to Figure 3 、 Figure 4 As shown in Figure 3 , the time period from t0 to t1 is the first target time period, that is, the time period when the device is in the idle state, the moment t2 is the target reference time, that is, the moment when the device is turned on or awakened to start working, and the time period from t3 to t4 is the second target time period, that is, the time period when the device is in the working state. Combining Figure 4 , when the device is in the idle state, multiple first temperatures within the time period from t0 to t1 are obtained. Among them, the maximum temperature value among the multiple first temperatures is T_01max, and the minimum temperature value is T_01min; if |T_01max - T_01min| ≤ 0.5 °C (i.e., the first preset temperature difference, and a specific value can be selected according to actual requirements, and no limitation is made here), it indicates that the external environmental temperature is in a stable state, that is, the multiple first temperatures detected by the device within the first target time period meet the first preset condition. At this time, the average temperature T1 of the multiple first temperatures within the time period from t0 to t1 is calculated, and at the same time, the device is turned off or the device is operated in a low-power state (in the low-power state, the influence of the heating components in the device on the temperature detected by the temperature sensor can be eliminated).

[0071] After the device is turned off or operates in a low-power state for a preset duration and then is turned on or awakened at time t2, that is, the device is turned on or awakened at the target reference time. At this time, the temperature of the temperature sensor has dropped to the ambient temperature. Obtain the reference ambient temperature value detected by the device at the target reference time, record the temperature T2 detected at this time, and T2 is the reference ambient temperature value. Calculate the difference △T_a (i.e., the first difference) between the first target temperature value and the reference ambient temperature value, △T_a = T1 - T2.

[0072] Obtain multiple second temperatures within the time period from t3 to t4 (i.e., the second target time period). Among them, the maximum temperature value of the multiple second temperatures is T_34max, and the minimum temperature value is T_34min. Determine whether |T_34max - T_34min| ≤ 0.5 °C (i.e., the second preset temperature difference, which can be selected according to actual needs and is not limited here) holds. If it holds (the ambient temperature is stable), that is, the multiple second temperatures detected by the device within the second target time period meet the second preset condition. Calculate the temperature average value T3 of the multiple second temperatures within the time period from t3 to t4, that is, the second target temperature value.

[0073] Calculate the difference △T_b (i.e., the second difference) between the second target temperature value and the reference ambient temperature value, △T_b = T3 - T2; if |△T_a - △T_b| ≤ 0.5 °C (i.e., the third preset temperature difference, which can be selected according to actual needs and is not limited here), that is, the absolute value of the difference between the first difference and the second difference is less than or equal to the third preset difference, it indicates that the ambient temperature is stable; calculate the current temperature calibration value △T, △T = (△T_a + △T_b) / 2, that is, take the average of the first difference and the second difference, and take the obtained average value as the current temperature calibration value of the device.

[0074] Among them, during the process of obtaining the current ambient temperature calibration value, when the situation of |T_01max - T_01min| > 0.5 °C, |T_34max - T_34min| > 0.5 °C, or |△T_a - △T_b| > 0.5 °C occurs, it indicates that the temperature of the environment where the device is located is unstable. Then, it is necessary to re-execute the steps of obtaining the current ambient temperature calibration value to ensure that the finally obtained current ambient temperature calibration value is obtained under the condition that the temperature of the environment where the device is located is stable, so as to obtain a more accurate ambient temperature in the environment where the device is located.

[0075] Step S120: Determine the target temperature calibration value according to the current temperature calibration value and the preset temperature calibration value.

[0076] In the embodiments of the present application, the current temperature calibration value is used to calibrate the temperature of the device by using the working heat of the device. In some embodiments, the device determines the target temperature calibration value according to the current temperature calibration value △T and the preset temperature calibration value, so as to select a suitable target temperature calibration value to correct the temperature calibration value of the device according to the different influences brought by different installation environments of the device and the drift of the heat generation power consumption of the device components, thereby obtaining a more reliable ambient temperature and enabling the device to automatically adapt to different installation environments and scenarios with different heat generation power consumptions.

[0077] Among them, the preset temperature calibration value can be pre-stored in the device, or the device can obtain it from the associated cloud or electronic device through wireless communication technology, or the device can obtain it from the associated electronic device through the serial communication interface. No specific limitation is made here.

[0078] Among them, the method for determining the target temperature calibration value according to the current temperature calibration value and the preset temperature calibration value can be to judge whether the difference between the current temperature calibration value and the preset temperature calibration value meets the third preset condition; if the difference between the current temperature calibration value and the preset temperature calibration value meets the third preset condition, the current temperature calibration value is determined as the target temperature calibration value; if the difference between the current temperature calibration value and the preset temperature calibration value does not meet the third preset condition, the preset temperature calibration value is determined as the target temperature calibration value.

[0079] In some embodiments, if the difference between the current temperature calibration value and the preset temperature calibration value is non-negative, judging whether the difference between the current temperature calibration value and the preset temperature calibration value meets the third preset condition can be to judge whether the difference between the current temperature calibration value and the preset temperature calibration value is greater than or equal to the preset threshold; if the difference between the current temperature calibration value and the preset temperature calibration value is greater than or equal to the preset threshold, the difference between the current temperature calibration value and the preset temperature calibration value meets the third preset condition, that is, it indicates that the preset temperature calibration value pre-stored in the device is not applicable to the current installation environment and the heat generation power consumption of the current device components. At this time, the obtained current temperature calibration value needs to be updated to the device to calibrate the detected ambient temperature, so as to eliminate the influence of different installation environments and heating components on the device ambient temperature detection and obtain a more accurate ambient temperature in the environment where the device is located; if the difference between the current temperature calibration value and the preset temperature calibration value is less than the preset threshold, the difference between the current temperature calibration value and the preset temperature calibration value does not meet the third preset condition, that is, it indicates that the preset temperature calibration value pre-stored in the device is applicable to the current installation environment and the heat generation power consumption of the current device components, and there is no need to update the obtained current temperature calibration value to the device.

[0080] In some other embodiments, if the difference between the current temperature calibration value and the preset temperature calibration value is negative, determining whether the difference between the current temperature calibration value and the preset temperature calibration value meets the third preset condition may be to determine whether the absolute value of the difference between the current temperature calibration value and the preset temperature calibration value is greater than or equal to a preset threshold; if the absolute value of the difference between the current temperature calibration value and the preset temperature calibration value is greater than or equal to the preset threshold, then the difference between the current temperature calibration value and the preset temperature calibration value meets the third preset condition; if the absolute value of the difference between the current temperature calibration value and the preset temperature calibration value is less than the preset threshold, then the difference between the current temperature calibration value and the preset temperature calibration value does not meet the third preset condition.

[0081] Step S130: Obtain the current actual temperature value detected by the device.

[0082] In the embodiments of the present application, the processor of the device obtains the current actual temperature value collected by the temperature sensor in the device. Wherein, the current actual temperature value includes: the temperature value of the components in the device generating heat and the actual ambient temperature value in the environment where the device is located.

[0083] Step S140: Obtain the actual ambient temperature value according to the target temperature calibration value and the current actual temperature value.

[0084] In the embodiments of the present application, the processor in the device obtaining the actual ambient temperature value according to the target temperature calibration value and the current actual temperature value may be to calculate the difference between the actual ambient temperature value and the target temperature calibration value, and use this difference as the actual ambient temperature value to obtain a more accurate ambient temperature value.

[0085] An ambient temperature acquisition method proposed in the embodiments of the present application includes obtaining a current temperature calibration value, which is used to calibrate the temperature of the device using the working heat of the device; determining a target temperature calibration value according to the current temperature calibration value and the preset temperature calibration value; obtaining the current actual temperature value detected by the device; and obtaining the actual ambient temperature value according to the target temperature calibration value and the current actual temperature value. Therefore, by adopting the above method of the present application, the current temperature calibration value of the device is obtained, and the target temperature calibration value is determined according to the current temperature calibration value and the preset temperature calibration value of the device, so as to correct the current actual temperature value obtained by the device using the target temperature calibration value to obtain the actual ambient temperature value, thereby enabling the device to self-calibrate the obtained ambient temperature, eliminating the influence of the secondary deviation between the detected ambient temperature and the actual ambient temperature caused by different installation environments of the device and the drift of the heat generation power consumption of the components, enabling the device to automatically adapt to different installation environments and different heat generation power consumption scenarios, and improving the accuracy of the device in obtaining the temperature of the environment where the device is located.
