[0002] Nowadays, electronic devices often have excessive temperatures when working. The main reason is that the electrical appliances inside the electronic devices are in a high power state for a long time. Excessive temperature of electronic devices will accelerate the aging of electrical appliances, reduce the service life of electronic devices, and even cause battery explosion, affecting user safety.

[0048] In order to better understand the technical solution of this specification, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0049] It should be clear that the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0050] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit this specification. The singular forms of "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0051] Nowadays, the temperature control method for electronic devices is usually to limit the peak power of each electrical appliance. Although this method can reduce the temperature of the electronic device, it may affect the performance of each electrical appliance in the electronic device. To address this problem, the embodiment of the present application provides a power control method, which adjusts the total power limit value based on the relationship between the average total power of the electronic device and the temperature control power threshold, so that the average total power of each electrical appliance is less than or equal to the total power limit value, which can effectively reduce the temperature of the device without affecting the performance of each electrical appliance.

[0052] Figure 1 This is a flow chart of a power control method provided in an embodiment of the present application. The method can be applied to electronic devices such as smart phones, tablet computers, etc. Figure 1 As shown, the method may include:

[0053] Step 101, determining the average total power of all electrical appliances in the previous period according to the load information of each electrical appliance.

[0054] The electrical appliances in the embodiments of the present application specifically refer to the devices contained in the electronic device, such as a processor, a speaker, a display screen, etc. When the electronic device performs different work tasks, the electrical appliances running inside it are not necessarily the same. For example, when the electronic device plays music in a black screen state, the processor and the speaker work, but the display screen does not work; when the user uses the electronic device to read the news, the processor and the display screen work, and the speaker does not work; when the electronic device plays a video, the processor, the speaker, and the display screen all work. When the electronic device performs a certain work task, each electrical appliance in the working state has a corresponding average power. The electronic device can calculate the average power of each electrical appliance based on the load information of each electrical appliance, and then obtain the average total power of all electrical appliances.

[0055] In one embodiment, the electronic device can obtain the load rate of each electrical appliance in the previous time period and the power corresponding to each electrical appliance at full load. The electronic device can determine the average power of each electrical appliance in the previous time period based on the load rate of each electrical appliance and the power corresponding to full load; the average total power of all electrical appliances in the previous time period can be determined based on the average power of each electrical appliance in the previous time period. Specifically, the electronic device multiplies the load rate of each electrical appliance with the power corresponding to full load to obtain the average power of each electrical appliance in the previous time period, and then the electronic device adds the average power of each electrical appliance to obtain the average total power of all electrical appliances in the previous time period. Among them, the electronic device needs to perform periodic cycle adjustment when adjusting the temperature, and the time covered by each cycle is defined as a time period. Under normal circumstances, the electronic device will adjust the relevant parameters of each electrical appliance in the current time period according to the average total power of the previous time period, and can adjust the relevant parameters of each electrical appliance in the next time period according to the average total power of the current time period.

[0056] Step 102: adjusting the total power limit value according to the relationship between the average total power in the previous period and the preset temperature control power threshold.

[0057] In the embodiment of the present application, the temperature control power threshold is the power value of the electronic device to meet the temperature control requirements. The average total power of all electrical appliances of the electronic device is positively correlated with the temperature of the electronic device. If the temperature of the electronic device is expected to meet the temperature control requirements, the average total power of all electrical appliances of the electronic device must not be greater than the temperature control power threshold. In actual operation, the electronic device adjusts the actual average total power through the total power limit value, and the average total power of all electrical appliances will not exceed the total power limit value.

[0058] In one embodiment, when the electronic device detects that the average total power of all electrical appliances in the previous time period is greater than the temperature control power threshold, the total power limit value will be reduced to reduce the average total power in the current time period. Furthermore, if the average total power that has been reduced in the current time period is still greater than the temperature control power threshold, the electronic device will continue to reduce the total power limit value in the next time period, so that the average total power in the next time period continues to decrease. When the electronic device detects that the average total power of all electrical appliances in the previous time period is less than the temperature control power threshold, in order to ensure the performance of each electrical appliance, the electronic device will increase the total power limit value to increase the average total power in the current time period. Furthermore, if the average total power that has been increased in the current time period is still less than the temperature control power threshold, the electronic device will continue to increase the total power limit value in the next time period, so that the average total power in the next time period continues to increase. It can be understood that in actual working scenarios, the average total power of all electrical appliances of the electronic device will fluctuate around the temperature control power threshold.

[0059] In one embodiment, when specifically adjusting the total power limit value, the electronic device may subtract the average total power of the previous time period from the temperature control power threshold to obtain a first power difference, and then subtract the first power difference from the total power limit value of the previous time period to obtain the total power limit value of the current time period.

[0060] In one embodiment, the electronic device may also determine a second power difference value based on the average total power in the previous time period and the temperature control power threshold, and then determine a power consumption conversion coefficient based on the work tasks performed by each electrical appliance in the current time period, and adjust the total power limit value in the current time period based on the second power difference value and the power consumption conversion coefficient. Specifically, the power consumption conversion coefficient is multiplied by the second power difference value to obtain a corrected power difference value, and the total power limit value of the current time period is obtained by subtracting the corrected power difference value from the total power limit value of the previous time period. It can be understood that the power consumption conversion coefficient can determine the adjustment speed of the total power limit value, and different power consumption conversion coefficients can be used to flexibly adjust the total power limit value for different electronic devices or different work tasks.

[0061] Step 103: adjusting the operating parameters of each electrical appliance according to the adjusted total power limit value.

[0062] In the embodiment of the present application, after the electronic device obtains the total power limit value of the current time period, it is necessary to determine the power limit value corresponding to each electrical appliance in the current time period according to the total power limit value, and then determine the working parameters corresponding to each electrical appliance in the current time period according to the power limit value of each electrical appliance in the current time period. Among them, the power limit value of each electrical appliance obtained from the total power limit value needs to be allocated in proportion according to the power demand of each electrical appliance. For example, the total power limit value can be allocated according to the ratio of the power of each electrical appliance at full load, or according to the ratio of the average power of each electrical appliance in the previous time period.

[0063] In one embodiment, when allocating the total power limit value, the electronic device may also determine the preset weight coefficient of each electrical appliance according to the work tasks performed by each electrical appliance in the current time period, and then determine the power limit value corresponding to each electrical appliance in the current time period according to the adjusted total power limit value and the preset weight coefficient of each electrical appliance. When performing different work tasks, different electrical appliances have different performance requirements. If a certain electrical appliance has a higher performance requirement, the preset weight coefficient of the electrical appliance can be set to a larger value so that the average power of the electrical appliance is larger to ensure performance, and at the same time, the preset weight coefficients of other electrical appliances are set to smaller values ​​so that the average power of other electrical appliances is smaller to ensure that the temperature control requirements are met.

[0064] Step 104 : Control each electrical appliance to perform a corresponding work task based on the work parameters, so that the average total power of all electrical appliances in the current period is less than or equal to the total power limit value.

[0065] The average power of each electrical appliance in the current time period is determined by the working parameters. The working parameters of different electrical appliances are different. If the electrical appliance is a processor, the working parameters may specifically refer to the frequency of the processor. If the electrical appliance is a display screen, the working parameters may specifically refer to the refresh rate and brightness, etc. Taking the processor as an example, the higher the frequency, the greater the average power, and the greater the brightness of the display screen, the greater the average power. After the electronic device determines the total power limit value of the current time period, it determines the working parameters of each electrical appliance in the current time period so that the average total power of all electrical appliances is less than or equal to the total power limit value, thereby ensuring that the temperature of the electronic device meets the temperature control requirements.

[0066] In an embodiment of the present application, the electronic device adjusts the total power limit value of the current time period based on the relationship between the average total power of the previous time period and the temperature control power threshold, thereby adjusting the average total power of each electrical appliance in the current time period, which can effectively reduce the device temperature without affecting the performance of each electrical appliance.

[0067] Figure 2A flowchart of another power control method provided in an embodiment of the present application. Figure 2 For example, the present application provides a power control method for further explanation, such as Figure 2 As shown, the method may include:

[0068] Step 201: Detect the work task currently executed by the electronic device.

[0069] Step 202: Determine a temperature control power threshold value P_target and a total power limit value P_total.

[0070] After the electronic device is turned on, it can detect the current work task in real time, and determine P_target and P_total according to the work task. When the electronic device performs different work tasks, its corresponding P_target and P_total are also different. For example, the device temperature when the user uses the electronic device to watch a video is usually higher than the device temperature when the user uses the electronic device to read a novel. Therefore, the P_target of the electronic device when playing a video is larger, and the P_target of the electronic device when displaying an article is smaller. Among them, the initial value of P_total can be determined by the performance of each electrical appliance. In the current work task, the sum of the average power of all electrical appliances involved that meet the performance requirements is P_total. Usually, the initial value of P_total will be higher than P_target.

[0071] In one embodiment, the electronic device will also detect the device temperature in real time, and only when it is detected that the device temperature is higher than the temperature threshold will the above P_target and P_total be determined and the subsequent power adjustment process be started. The temperature threshold is a value close to the expected temperature and less than the expected temperature. Taking video playback as an example, the electronic device hopes that the temperature when playing the video is not higher than 42 degrees (that is, the expected temperature is 42 degrees). Then, if it is detected that the current device temperature exceeds 35 degrees, P_target and P_total can be determined and the subsequent adjustment process can be started (that is, the temperature threshold is 35 degrees) to dynamically control the device temperature. When the electronic device performs different work tasks, the temperature threshold for starting the power adjustment process is also different. Generally, when the electronic device performs a certain work task, the greater the average total power of all electrical appliances, the greater the corresponding expected temperature and temperature threshold.

[0072] Step 203, calculating the average power of each electrical appliance in the previous period according to the load information.

[0073] The electronic device can calculate the average power of each electrical appliance in the previous period based on the load information of each electrical appliance in the previous period. Taking the processor as an example, the electronic device can calculate the average power according to the formula P_i=full load power at the current frequency*load rate.

[0074] Step 204, calculating the average total power P_sum of all electrical appliances in the previous period.

[0075] The average power (P_1, P_2, ..., P_i) of each electrical appliance in the previous period is calculated and summed to obtain the average total power P_sum of all electrical appliances in the previous period. P_sum is compared with P_target, and P_total is dynamically adjusted according to the difference. If P_sum is greater than P_target, P_total is reduced; if P_sum is less than P_target, P_total is increased.

[0076] Step 205, increase P_total.

[0077] Step 206: Decrease P_total.

[0078] The electronic device adjusts P_total according to the formula P_total=P_total-coef*(P_sum-P_target), where coef is the power consumption conversion coefficient, and coef is usually set to (0, 1). The larger the value of coef, the greater the adjustment amplitude of P_total in each iteration.

[0079] Step 207, P_total allocation.

[0080] After adjusting P_total, the electronic device can distribute each P_total, that is, determine the power limit value (P_total1, P_total2, ..., P_total1) of each electrical appliance in the current time period according to P_total.

[0081] The electronic device can allocate P_total according to the power demand of each electrical appliance, or according to the ratio of the average power of each electrical appliance in the previous period. Specifically, the electronic device can allocate P_total according to the formula Calculate the power limit value of each electrical appliance, where coef_x is the preset weight coefficient of each electrical appliance. As can be seen from the formula, the larger the coef_x, the larger the power limit value of the electrical appliance, and the more its performance can be guaranteed during operation. Electronic devices can set different preset weight coefficients for each electrical appliance in advance according to different work tasks. For example, if the electronic device plays a video, the performance of the display screen must be guaranteed, and the average power cannot be too low. When the electronic device performs this work task, the preset weight coefficient of the display screen will be set higher to ensure that the video can be played smoothly.

[0082] Step 208, determining the operating parameters of each electrical appliance.

[0083] The electronic device adjusts the working parameters according to the power limit value allocated to each electrical appliance so that the average total power in the current time period does not exceed the total power limit value.

[0084] The value changes after multiple iterations can be shown as Figure 3 As shown, Figure 3 The dotted line with a fixed value is P_target, the solid curve is P_total, and the dotted curve is P_sum. Each change in the value indicates the entry into the next time period. Taking the moment indicated by arrow 301 as an example, the electronic device detects that P_sum is greater than P_target, so it reduces P_total, so that P_sum in the next time period decreases, thereby meeting the temperature control requirements; and at the moment indicated by arrow 302, the electronic device detects that P_sum is less than P_target, so it increases P_total, so that P_sum in the next time period increases, thereby meeting the performance requirements; but P_sum may not increase to be greater than P_target. At the moment indicated by arrow 303, P_sum is still less than P_target, so the electronic device continues to increase P_total, so that P_sum in the next time period increases, further meeting the performance requirements.

[0085] In an embodiment of the present application, the electronic device can achieve a dynamic balance between temperature control requirements and performance requirements by adjusting the total power limit value based on the relationship between the average total power and the temperature control power threshold, and can effectively reduce the device temperature without affecting the performance of each electrical appliance.
