[0041] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] The acquisition, storage, use, and processing of data in the technical solution disclosed in this disclosure are in compliance with the relevant provisions of national laws and regulations.

[0044] Figure 1 is a flow chart of a method for obtaining heat dissipation parameters according to an exemplary embodiment. Figure 1 As shown, the method for obtaining heat dissipation parameters of the embodiment of the present disclosure includes the following steps.

[0045] S101, obtaining a target current value corresponding to the electronic device when the output power value of the electronic device is a target power value.

[0046] It should be noted that the execution subject of the method for obtaining the heat dissipation parameters of the embodiment of the present disclosure is an electronic device, and the electronic device includes a mobile phone, a notebook, a desktop computer, a vehicle-mounted terminal, a smart home appliance, a wearable device, etc. Among them, the wearable device may include a wrist-worn device (such as a smart watch, a smart bracelet), a head-worn device, a foot-worn device, etc. The method for obtaining the heat dissipation parameters of the embodiment of the present disclosure can be executed by the device for obtaining the heat dissipation parameters of the embodiment of the present disclosure, and the device for obtaining the heat dissipation parameters of the embodiment of the present disclosure can be configured in any electronic device to execute the method for obtaining the heat dissipation parameters of the embodiment of the present disclosure.

[0047] It should be noted that the target current value refers to the reference output current value of the electronic device when the output power value of the electronic device is the target power value. The reference output current value refers to the ideal output current value of the electronic device under a certain operating state, which can be calibrated or calculated in advance. The target current value is a reference output current value. The target power value refers to the ideal output power value of the electronic device during the measurement process, which can be calibrated or calculated in advance. There are no excessive restrictions on the target power value and the target current value.

[0048] In one implementation, a mapping relationship between the output power value of the electronic device and the reference output current value can be pre-established, the mapping relationship can be queried based on the target power value, and the output power value can be used as the reference output current value mapped to the target power value as the target current value.

[0049] S102, obtaining an actual output current value of the electronic device.

[0050] It should be noted that the actual output current value refers to the real output current value of the electronic device under a certain operating state, which can be measured. The measurement of the actual output current value of the electronic device can be achieved by using any electronic device output current value measurement method in the relevant technology, and no further restrictions are made here.

[0051] In one embodiment, measuring the actual output current value of the electronic device includes measuring the actual output current value of the electronic device according to a set period, so as to achieve periodic measurement of the actual output current value. It should be noted that there are no excessive restrictions on the set period, such as 50 milliseconds, 200 milliseconds, 1 second, 2 seconds, 3 seconds, etc.

[0052] S103, determining whether the target current value and the actual output current value meet the test condition, and obtaining a first operating parameter of the electronic device, wherein the first operating parameter is determined by the electronic device when the second operating parameter remains unchanged.

[0053] In the embodiment of the present disclosure, if the target current value and the actual output current value do not meet the test condition, the first operating parameter is not obtained at this time, and the heat dissipation parameter is not obtained, that is, the first operating parameter is obtained only when the target current value and the actual output current value meet the test condition, and then the heat dissipation parameter is obtained. It can be understood that the test condition refers to the condition for obtaining the first operating parameter, and also refers to the condition for obtaining the heat dissipation parameter.

[0054] In one embodiment, the method further includes identifying whether the target current value and the actual output current value satisfy a test condition.

[0055] In some examples, identifying whether a test condition is satisfied based on the target current value and the actual output current value includes obtaining a difference between the target current value and the actual output current value, and identifying whether the test condition is satisfied based on the difference.

[0056] In some examples, whether the test condition is met is identified based on the difference, including if the absolute value of the difference is greater than a first set threshold, it indicates that the target current value and the actual output current value differ greatly, that is, the actual output power value of the electronic device differs greatly from the target power value, and it is identified that the test condition is not met. Conversely, if the absolute value of the difference is less than or equal to the first set threshold, it indicates that the target current value and the actual output current value differ little, that is, the actual output power value of the electronic device differs little from the target power value, and it is identified that the test condition is met.

[0057] It should be noted that the first set threshold mentioned in the above example is not excessively limited. For example, the first set threshold may be the product of the target current value and the current error coefficient, wherein the current error coefficient may be an empirical value, for example, the current error coefficient may be 0.1.

[0058] In some examples, whether the test condition is satisfied based on the difference recognition includes determining the target interval where the difference is located from multiple candidate intervals, and obtaining the recognition result mapped to the target interval. Among them, the recognition result includes satisfying the test condition and not satisfying the test condition. It can be understood that the value interval of the difference can be divided into multiple candidate intervals in advance, and a mapping relationship between each candidate interval and the recognition result is established. Different candidate intervals can map the same recognition result or different recognition results, and no excessive restrictions are made here.

[0059] In the embodiment of the present disclosure, the first operating parameter is determined by the electronic device when the second operating parameter remains unchanged, that is, the second operating parameter is not adjusted during the process of obtaining the first operating parameter.

[0060] It should be noted that there are no excessive restrictions on the first operating parameter and the second operating parameter.

[0061] For example, the first operating parameter includes an output power value and a temperature value of the electronic device. The temperature value of the electronic device may include a temperature value of a target area of ​​the electronic device. The target area is an area with the highest temperature of the electronic device. For example, taking the electronic device as a mobile phone, the target area may be any one of the front, back, and side of the mobile phone.

[0062] For example, the second operating parameter includes the frequency and load of processors such as a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit), and the backlight brightness of the electronic device.

[0063] S104: Determine a heat dissipation parameter of the electronic device based on the first operating parameter.

[0064] It should be noted that the process of determining the heat dissipation parameter based on the first operating parameter can be implemented by using any heat dissipation parameter calculation method in the relevant technology, and no further limitation is made here.

[0065] In one embodiment, before determining the heat dissipation parameter of the electronic device based on the first operating parameter, it also includes identifying that the measurement duration reaches a set duration. It should be noted that there is no excessive limitation on the set duration, for example, the set duration can be 15 minutes.

[0066] In one embodiment, determining a heat dissipation parameter of the electronic device based on the first operating parameter includes determining the heat dissipation parameter based on a plurality of first operating parameters within a set time period.

[0067] In one embodiment, the first operating parameter includes an output power value and a temperature value of the electronic device. Based on the first operating parameter, a heat dissipation parameter of the electronic device is determined, including determining the heat dissipation parameter based on a second average value of multiple output power values, a third average value of temperature values ​​of multiple electronic devices, and an ambient temperature value.

[0068] In some examples, the thermal parameters are calculated as follows:

[0069] Heat dissipation parameter=second average value / (third average value-ambient temperature value).

[0070] For example, taking the electronic device as a mobile phone, if the area with the highest temperature of the mobile phone, that is, the target area, is the back of the mobile phone, and if the test conditions are met, the output power value of the mobile phone and the temperature value of the back of the mobile phone are measured, and in response to the measurement time reaching 15 minutes, the second average value of multiple output power values ​​of the mobile phone within 15 minutes, the third average value of multiple temperature values ​​on the back of the mobile phone within 15 minutes and the ambient temperature value can be obtained to determine the heat dissipation parameters.

[0071] The method for obtaining heat dissipation parameters provided by the embodiment of the present disclosure obtains the target current value corresponding to the electronic device when the output power value of the electronic device is the target power value, obtains the actual output current value of the electronic device, determines whether the target current value and the actual output current value meet the test conditions, and obtains the first operating parameter of the electronic device, wherein the first operating parameter is determined by the electronic device when the second operating parameter remains unchanged, and the heat dissipation parameter of the electronic device is determined based on the first operating parameter. Thus, the target current value can be determined based on the target power value, and the first operating parameter is not obtained until the target current value and the actual output current value meet the test conditions, which helps to improve the accuracy of the heat dissipation parameters.

[0072] Based on any of the above embodiments, the method further includes determining that the target current value and the actual output current value do not meet the test condition, returning to obtain the actual output current value of the electronic device and subsequent steps until the target current value and the actual output current value meet the test condition. Thus, when the test condition is not met, the actual output current value continues to be obtained, and whether the test condition is met is re-identified based on the target current value and the re-acquired actual output current value.

[0073] Figure 2 is a flow chart showing a method for obtaining heat dissipation parameters according to another exemplary embodiment. Figure 3 As shown, the method for obtaining heat dissipation parameters of the embodiment of the present disclosure includes the following steps.

[0074] S201, obtaining a target current value corresponding to the electronic device when the output power value of the electronic device is a target power value.

[0075] S202, obtaining an actual output current value of the electronic device.

[0076] For the relevant contents of steps S201 - S202 , please refer to the above embodiment and will not be described again here.

[0077] S203, obtaining a first average value of the sorted N actual output current values ​​of the electronic devices, wherein the multiple actual output current values ​​are sorted from early to late according to the acquisition time, and N is a positive integer.

[0078] S204: Based on the target current value and the first average value, identify whether a test condition is met.

[0079] It should be noted that the sorted N actual output current values ​​refer to the latest set of actual output current values ​​obtained, and the first average value refers to the average value of the latest set of actual output current values ​​obtained. N is not limited too much, for example, N is 5, 10, etc.

[0080] For example, the actual output current value of the electronic device includes current values ​​1 to 10, and the current values ​​1 to 10 are sorted from early to late according to the acquisition time, and the sorting result is current values ​​1 to 10, that is, the acquisition time of current value 1 is the earliest, and the acquisition time of current value 10 is the latest. Taking N=5 as an example, the first average value of current values ​​6 to 10 can be obtained, and based on the target current value and the first average value, it is identified whether the test condition is met.

[0081] If the test condition is not met, the actual output current value of the electronic device can be further obtained to obtain current values ​​11 to 13. The updated actual output current value of the electronic device includes current values ​​1 to 13. The current values ​​1 to 13 are sorted from early to late according to the acquisition time. The sorting result is current values ​​1 to 13, that is, the acquisition time of current value 1 is the earliest, and the acquisition time of current value 13 is the latest. The first average value of current values ​​9 to 13 can be obtained, and based on the target current value and the first average value, it is identified whether the test condition is met.

[0082] In one embodiment, based on the target current value and the first average value, identifying whether the test condition is met includes obtaining the difference between the target current value and the first average value, determining the target interval where the difference is located from multiple candidate intervals, and obtaining the recognition result of the target interval mapping. The recognition result includes whether the test condition is met or not.

[0083] In one embodiment, based on the target current value and the first average value, identifying whether the test condition is met includes obtaining the absolute value of the difference between the target current value and the first average value. If the absolute value is greater than a first set threshold value, it indicates that there is a large difference between the target current value and the first average value, that is, there is a large difference between the actual output power of the electronic device and the target power value, and it is identified that the test condition is not met. If the absolute value is less than or equal to the first set threshold value, it indicates that there is a small difference between the target current value and the first average value, that is, there is a small difference between the actual output power of the electronic device and the target power value, and it is identified that the test condition is met.

[0084] S205, if the test condition is not met, return to execute the actual output current value of the electronic device and subsequent steps until the test condition is met.

[0085] S206: Acquire a first operating parameter of the electronic device, where the first operating parameter is determined by the electronic device when the second operating parameter remains unchanged.

[0086] S207: Determine a heat dissipation parameter of the electronic device based on the first operating parameter.

[0087] For the relevant contents of steps S205-S207, please refer to the above embodiment and will not be repeated here.

[0088] The method for obtaining heat dissipation parameters provided by the embodiment of the present disclosure obtains the first average value of the actual output current values ​​of the N electronic devices after sorting, wherein the multiple actual output current values ​​are sorted from early to late according to the acquisition time, and whether the test condition is met is identified based on the target current value and the first average value. Thus, the first average value of the actual output current values ​​of the N electronic devices after sorting can be obtained, and the target current value and the first average value can be comprehensively considered to identify whether the test condition is met, which helps to improve the recognition accuracy of the test condition, thereby improving the accuracy of the heat dissipation parameters.

[0089] Based on any of the above embodiments, after measuring the actual output current value of the electronic device in step S102, the step further includes obtaining the standard deviation of the sorted N actual output current values.

[0090] Figure 3 is a flow chart showing a method for obtaining heat dissipation parameters according to another exemplary embodiment. Figure 3 As shown, the method for obtaining heat dissipation parameters of the embodiment of the present disclosure includes the following steps.

[0091] S301, obtaining a target current value corresponding to the electronic device when the output power value of the electronic device is a target power value.

[0092] S302, obtaining an actual output current value of the electronic device.

[0093] S303, obtaining a first average value of the sorted N actual output current values ​​of the electronic devices, wherein the multiple actual output current values ​​are sorted from early to late according to the acquisition time, and N is a positive integer.

[0094] S304, obtaining an absolute value of a difference between the target current value and the first average value.

[0095] For the relevant contents of steps S301 - S304 , please refer to the above embodiments and will not be described again here.

[0096] S305: If the absolute value is less than or equal to the first set threshold, and the last standard deviation of the sorting is greater than the second set threshold, it is identified that the test condition is not met, wherein the multiple standard deviations are sorted from early to late according to the acquisition time.

[0097] It should be noted that the standard deviation at the end of the sorting refers to the standard deviation with the latest acquisition time, and there is no excessive limitation on the second set threshold.

[0098] In an embodiment of the present disclosure, if the absolute value is less than or equal to the first set threshold, and the standard deviation at the end of the sorting is greater than the second set threshold, it indicates that the difference between the target current value and the first average value is small, that is, the difference between the actual output power of the electronic device and the target power value is small, and the discrete degree of a group of actual output current values ​​acquired at the latest time is large, that is, the actual output current value of the electronic device fluctuates greatly and is unstable, that is, the output power value of the electronic device fluctuates greatly and is unstable, and it is identified that the test conditions are not met.

[0106] S309: If the test condition is not met and the absolute value is greater than the first set threshold, the second operating parameter is adjusted, and the process returns to execute the steps of obtaining the actual output current value of the electronic device and subsequent steps.

[0107] In an embodiment of the present disclosure, if the test condition is not met and the absolute value is greater than the first set threshold, it indicates that there is a large difference between the target current value and the first average value, that is, there is a large difference between the actual output power of the electronic device and the target power value. The second operating parameter is adjusted, and the process returns to execute the actual output current value of the electronic device and its subsequent steps.

[0108] In one embodiment, adjusting the second operating parameter may include obtaining an adjustment amount of the second operating parameter based on the absolute value, and adjusting the second operating parameter according to the adjustment amount. For example, the absolute value is positively correlated with the adjustment amount.

[0109] In one embodiment, adjusting the second operating parameter may include determining an adjustment amount of the second operating parameter based on the category of the second operating parameter, and adjusting the second operating parameter according to the adjustment amount. It is understandable that different second operating parameters may correspond to different adjustment amounts.

[0110] For example, the adjustment amount can be set to 1 gear, which can achieve graded adjustment of the second operating parameter.

[0111] For example, the adjustment amount can be set to 1%, 10%, etc. of the second operating parameter, so as to achieve linear adjustment of the second operating parameter.

[0112] In one embodiment, adjusting the second operating parameter may include obtaining an adjustment direction of the second operating parameter based on a magnitude relationship between the target current value and the first average value, and adjusting the second operating parameter according to the adjustment direction. For example, if the first current value is greater than the target average value, the adjustment direction may be determined to be decreasing, and if the first current value is less than the target average value, the adjustment direction may be determined to be increasing.

[0113] S310, if the test condition is not met and the absolute value is less than or equal to the first set threshold, the second operating parameter remains unchanged, and the process returns to executing the actual output current value of the electronic device and subsequent steps until the test condition is met.

[0114] In an embodiment of the present disclosure, if the test condition is not met and the absolute value is less than or equal to the first set threshold value, it indicates that the difference between the target current value and the first average value is small, that is, the difference between the actual output power of the electronic device and the target power value is small, the second operating parameter remains unchanged, and the process returns to execute the actual output current value of the electronic device and its subsequent steps until the test condition is met.

[0115] S311: If the test condition is met, obtain a first operating parameter of the electronic device, wherein the first operating parameter is determined by the electronic device when the second operating parameter remains unchanged.

[0117] For the relevant contents of steps S311 - S312 , please refer to the above embodiments and will not be described again here.

[0118] The method for obtaining the heat dissipation parameters provided by the embodiment of the present disclosure, if the absolute value is less than or equal to the first set threshold, can comprehensively consider the size relationship between the last set of standard deviations and the second set threshold to identify whether the test conditions are met, that is, the discrete degree of the actual output current value can be considered to identify whether the test conditions are met, which helps to improve the recognition accuracy of the test conditions, thereby improving the accuracy of the heat dissipation parameters. In addition, when the test conditions are not met and the absolute value is large, the second operating parameter can be adjusted to adjust the actual output current value to adjust the output power value so that the output power value is closer to the target power value.

[0119] Based on any of the above embodiments, the second operating parameter is adjusted in step S309, including when the first average value is greater than the target current value, indicating that the average value of the output power value is greater than the target power value, reducing the second operating parameter to reduce the actual output current value, and then reducing the output power value, so that the output power value is closer to the target power value.

[0120] When the first average value is less than the target current value, it indicates that the average value of the output power value is less than the target power value. The second operating parameter is increased to increase the actual output current value, thereby increasing the output power value, so that the output power value is closer to the target power value.

[0121] In one embodiment, the electronic device is equipped with a central processor, and the second operating parameter is adjusted, including adjusting the frequency of the central processor, adjusting the load of the central processor in response to the completion of the frequency adjustment of the central processor, and adjusting the backlight brightness of the electronic device in response to the completion of the load adjustment of the central processor. Thus, multiple second operating parameters can be adjusted in the order of the frequency of the central processor, the load of the central processor, and the backlight brightness.

[0122] In some examples, the electronic device is equipped with a graphics processor, and adjusting the second operating parameter also includes adjusting the frequency of the graphics processor in response to the completion of the backlight brightness adjustment of the electronic device, and adjusting the load of the graphics processor in response to the completion of the frequency adjustment of the graphics processor. Thus, the multiple second operating parameters can be adjusted in the order of the frequency of the central processor, the load of the central processor, the backlight brightness, the frequency of the graphics processor, and the load of the graphics processor.
