Description

Power consumption control method of electronic equipment and electronic equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a power consumption control method for an electronic device and an electronic device.

Background

Along with the performance of electronic equipment such as smart phones, tablet computers and intelligent wearable equipment is stronger and stronger, the heat generation is also larger and larger, and the temperature control becomes one of the key elements of the performance management of the electronic equipment. With the development of various services (such as applications) on electronic equipment and the improvement of requirements on hardware performance, various overheating problems of terminals emerge endlessly, and temperature control becomes an urgent concern.

At present, an existing temperature control scheme for a mobile phone mainly relies on power consumption control (IPA) of an intelligent electronic device, monitors the temperature and load of the electronic device in real time, and automatically reduces the operating frequency of a System On Chip (SOC) when the temperature is too high, for example, the temperature threshold of the electronic device of the mobile phone is 40 ℃, and the mobile phone limits the CPU frequency to below 1.5GHz when the temperature exceeds 40 ℃. Although power consumption can be reduced and temperature control can be achieved, the reduction of the working frequency can affect normal processing of services, and the mobile phone may have the problems of picture blocking, slow application starting speed, slow page refreshing, or frame dropping during sliding probabilistically, which causes poor use experience for users.

Because the actual total power consumption in the first period is equal to the sum of the actual power consumption of the at least one system-level chip and the actual power consumption of the M peripheral devices, when the electronic device determines that the actual total power consumption is greater than or equal to the first power consumption threshold, the electronic device reduces the power consumption of all or part of the M peripheral devices.

In the embodiment of the application, the method can control the system power consumption of the electronic equipment by reducing the power consumption of the peripheral device without reducing the frequency of the SOC, thereby ensuring that the system performance of the electronic equipment is not obviously reduced.

In one possible design, after the electronic device reduces the first operating parameter to the second parameter value, when it is determined that the actual total power consumption in the second period is smaller than a second power consumption threshold, where the second power consumption threshold is smaller than the first power consumption threshold, the following processing is performed for the first operating parameter of the first peripheral device: increasing the first working parameter from the second parameter value to a third parameter value, and acquiring the actual power consumption of at least one system-level chip and the actual power consumption of M peripheral devices in a third period; calculating the actual total power consumption of the electronic equipment in the third time period, and increasing the first peripheral device from the third parameter value to a fourth parameter value when the actual total power consumption in the third time period is determined to be smaller than the second power consumption threshold; and stopping increasing the fourth parameter value when the actual total power consumption in the third time period is determined to be larger than or equal to the second power consumption threshold.

In the embodiment of the present application, the value of the operating parameter is gradually increased, so as to make the adjustment of the power consumption of the electronic device to be imperceptible to the user as much as possible, so as to ensure the user experience of the user.

An embodiment of the present application provides a method for controlling power consumption of an electronic device, where as shown in fig. 4a, the method may be executed by the electronic device, and the method includes:

step 401, the electronic device collects actual power consumption of at least one SOC and actual power consumption of M peripheral devices in a first period, and calculates actual total power consumption of the electronic device in the first period.

The duration corresponding to the first period may be 50ms, and the actual total power consumption in the first period is equal to the sum of the actual power consumption of the system-on-chip and the actual power consumption of the M peripheral devices in the first period. For example, the system-on-chip in the mobile phone has a CPU and a GPU, and the peripheral devices have a screen and a speaker, then the first actual total power consumption includes the power consumption of the CPU, the power consumption of the GPU, the power consumption of the screen, and the power consumption of the speaker.

For example, for SOCs such as CPUs, DDRs and GPUs, the calculation formula of power consumption is UIt, where U is a voltage value, I is a current value, and t is an operating time; calculating the average power consumption for the power consumption difference value of the given model of LCD (LCD upper limit brightness order-current brightness order), wherein the LCD measuring range is 255 orders, and the average power consumption is 1.XmA orders; the average power consumption is calculated for the speaker power consumption difference value (volume upper limit value-current volume).

That is, the mobile phone can calculate the actual power consumption of the CPU by collecting the voltage and current of the CPU and combining the duration corresponding to the first time period; for a screen, a speaker and the like, the power consumption corresponding to the screen can be determined according to the brightness and the volume of the screen, and various power consumption methods for acquiring the SOC and peripheral devices are provided in the prior art, which are not listed here.

Step 402, when the actual total power consumption in the first time period is greater than or equal to a preset first power consumption threshold, the electronic device reduces the power consumption of the N peripheral devices, so that the actual total power consumption of the electronic device is controlled within the first power consumption threshold.

The N peripheral devices are all or part of the M peripheral devices, and N and M are positive integers greater than or equal to 1. That is, the electronic device reduces the power consumption of all or part of the peripheral devices, so that the actual total power consumption of the electronic device can be controlled within the first power consumption threshold.

Specifically, the electronic device may reduce power consumption by reducing the power consumption budget configured by each peripheral device for the next time period. That is to say, in the embodiment of the present application, the electronic device reduces the power consumption budget of all or part of the peripheral devices in the next period, and ensures that the power consumption budget of the system-on-chip is not reduced as much as possible, so as to ensure that the operating frequency of the SOC remains unchanged, thereby ensuring the performance stability of the system, and avoiding the problems of stumbling, slow refresh rate, and the like. For example, the system-on-chip in the mobile phone includes a CPU and a GPU, and the peripheral devices include a screen and a speaker. And if the mobile phone detects that the actual total power consumption of the mobile phone in the first time interval exceeds a preset first power consumption threshold value, reducing the power consumption budgets of the screen and the loudspeaker in the next time interval so that the actual total power consumption of the mobile phone can fall back to be within the preset first power consumption threshold value. The method can control the system power consumption of the electronic equipment by reducing the power consumption of the peripheral device without reducing the working frequency of the SOC, thereby ensuring that the system performance of the electronic equipment is not obviously reduced.

It should be noted that, before performing step 401, the electronic device may determine the first power consumption threshold according to a current state, where the current state may include at least one of its own electronic device temperature, ambient light brightness, operating state, temperature rising rate, and current ambient temperature. For example, the environmental temperature in winter and summer are different, so the first power consumption threshold preset by the mobile phone in summer is greater than the first power consumption threshold in winter, and in addition, the indoor and outdoor environmental light brightness is different, so the temperature rise amplitude when the mobile phone is irradiated is also different, and therefore, the specific value of the first power consumption threshold is also different under different environmental light brightness.

In a possible embodiment, when the electronic device determines that the first actual total power consumption is greater than or equal to the first power consumption threshold, any one of the following manners may be performed for the first operating parameter of the first peripheral device of the N peripheral devices.

It should be noted that the first peripheral device is any one of the N peripheral devices, and the first operating parameter is any one of screen brightness, speaker volume, charging voltage, charging current, bluetooth transmission power, wireless fidelity WIFI transmission power, and modem transmission power.

Specifically, the embodiments of the present application focus on the following three ways in conjunction with fig. 4 b.

In the first mode, the processor of the electronic device issues the lowest parameter value of the first operating parameter to the first peripheral device at the first time, and the first peripheral device immediately reduces the current first operating parameter from the first parameter value to the lowest parameter value.

For example, the processor of the handset issues the lowest brightness level 2 of the screen brightness to the screen at a first time, which immediately reduces the screen brightness from brightness level 4 to brightness level 2.

In a second mode, the processor of the electronic device issues the lowest parameter value of the first operating parameter to the first peripheral device at the first time T1, and the first peripheral device gradually decreases the first operating parameter from the first parameter value to the lowest parameter value in multiple times according to the set step length in the following second time period T2.

For example, the processor of the mobile phone issues the lowest brightness level 2 of the screen brightness to the screen at the first time t1, and the screen brightness is reduced from brightness level 4 to brightness level 3, and then from brightness level 3 to brightness level 2.

Third, the electronic device issues the second parameter value of the first operating parameter to the first peripheral device at a first time T1, then the first peripheral device immediately reduces the first operating parameter from the first parameter value to the second parameter value, then the electronic device further counts the actual total power consumption in a second time period T2, if the actual total power consumption in the second time period T2 is still greater than the first power consumption threshold, the electronic device issues the third parameter value of the first operating parameter to the first peripheral device at a second time T2, then the first peripheral device immediately reduces the first operating parameter from the second parameter value to the third parameter value, and the above steps are repeatedly executed in sequence until the actual total power consumption of the electronic device is less than the first power consumption threshold, and then the reduction of the parameter value of the first operating parameter is stopped. The reason for gradually reducing the value of the first operating parameter is to make the adjustment of the power consumption of the electronic device imperceptible to the user as much as possible, so as to ensure the user experience.

In a fourth mode, the electronic device issues the first compensation value of the first operating parameter to the first peripheral device at a first time t1, then the first peripheral device immediately determines a second parameter value obtained by subtracting the first compensation value from the first parameter value of the first operating parameter and reduces the second parameter value to the second parameter value, then the electronic device further counts the actual total power consumption in the second time period T2, and if the actual total power consumption in the second time period T2 is still greater than the first power consumption threshold, the electronic device issues a second compensated value of the first operating parameter to the first peripheral device at a second time t2, the first peripheral device then immediately determines a third parameter value of the first operating parameter that decreases from the second parameter value to the second offset value, and reducing to a third parameter value, and repeating the steps in sequence until the actual total power consumption of the electronic equipment is less than the first power consumption threshold, and stopping reducing the parameter value of the first working parameter.

For example, the processor of the mobile phone issues the brightness level 3 of the screen brightness to the screen at the first time T1, the screen first reduces the screen brightness from the brightness level 4 to the brightness level 3, then the processor of the mobile phone counts the actual total power consumption in the second time period T2, if the actual total power consumption in the second time period T2 is greater than or equal to the first power consumption threshold, the processor of the mobile phone issues the brightness level 2 of the screen brightness to the screen at the second time T2, the screen first reduces the screen brightness from the brightness level 3 to the brightness level 2, the processor of the mobile phone counts the actual total power consumption in the third time period T3, and if the actual total power consumption in the third time period T3 is less than the first power consumption threshold, the reduction of the screen brightness is stopped.

It should be noted that, when the power consumption of the peripheral device is reduced, the current operation state of the electronic device needs to be considered. If the electronic equipment is running the first service, determining the priority order of each peripheral device to be a first peripheral device, a second peripheral device and a third peripheral device, namely the first peripheral device is least related to the first service, the second peripheral device and the third peripheral device, preferentially reducing the first working parameter of the first peripheral device, then reducing the second working parameter of the second peripheral device and finally reducing the third working parameter of the third peripheral device.

And if the electronic equipment is running the second service and only the first peripheral device is determined to be irrelevant to the second service, only reducing the first working parameter of the first peripheral device.

By way of example, the current operating state may refer to a video being played on the electronic device, or a game being played on the electronic device, such as a chat application being currently running on the electronic device. For example, when the electronic device is in the running state of a battle game, the priority of each peripheral device may be bluetooth, a speaker and a screen in descending order, the mobile phone may give priority to reducing the bluetooth transmission power, and then the volume of the speaker and the brightness of the screen, because the user is more concerned about the interface response speed when playing the game, the bluetooth transmission power, the volume and the brightness are moderately reduced, which does not greatly affect the user experience, and if the operating frequency of the CPU is reduced, the electronic device may be stuck. For another example, when the electronic device is currently in a music playing operation state, the priority of each peripheral device may be from low to high, namely bluetooth and the screen, and the mobile phone may give priority to reducing the bluetooth transmission power and then the brightness of the screen. Since when listening to music, reducing the volume may have some impact on the user experience, but reducing the brightness of the screen generally does not have an impact on the user experience.

In a possible embodiment, after the electronic device reduces the values of the operating parameters of the peripheral devices according to the method, if the temperature of the electronic device is lower than the temperature threshold value in a plurality of consecutive periods, and it is determined that the actual total power consumption of the electronic device is smaller than the second power consumption threshold in a certain period, the values of the operating parameters of the N peripheral devices are increased. Wherein the second power consumption threshold is less than the first power consumption threshold. For example, assuming that the first power consumption threshold is PL0, the second power consumption threshold may be PL0 multiplied by 80%.

Referring to fig. 4b, assuming that the electronic device temperature of the electronic device is lower than the temperature threshold value in the T2 time period, if the actual total power consumption in the T2 time period is lower than the second power consumption threshold, the processor may perform any one of the following manners.

In the first mode, after the processor of the electronic device issues the preset parameter value of the first operating parameter to the first peripheral device at the second time t2, the first peripheral device immediately increases the first operating parameter from the second parameter value to the preset parameter value.

For example, the processor of the mobile phone issues a preset brightness level of 4 for the screen brightness to the screen at the second time t2, and the screen immediately increases the screen brightness from brightness level 2 to brightness level 4.

In the second mode, after the processor of the electronic device issues the preset parameter value of the first operating parameter to the peripheral device, the peripheral device gradually increases the first operating parameter from the second parameter value to the preset parameter value in multiple times according to the set step length in the following third time period T3.

For example, the processor of the mobile phone issues a preset brightness level 4 of the screen brightness to the screen at a second time t2, and the screen brightness is increased from brightness level 2 to brightness level 3, and then from brightness level 3 to brightness level 4.

Third, the processor of the electronic device issues the third parameter value of the first operating parameter to the first peripheral device at the second time T2, then the first peripheral device immediately increases the current first operating parameter from the second parameter value to the third parameter value, then the electronic device further counts the actual total power consumption in the third time period T3, if the actual total power consumption in the third time period T3 is still less than the second power consumption threshold, the electronic device issues the fourth parameter value of the first operating parameter to the first peripheral device at the third time T3, then the first peripheral device immediately increases the first operating parameter from the third parameter value to the fourth parameter value, and the above steps are repeatedly executed in sequence until the actual total power consumption of the electronic device falls within the threshold interval that is less than the first power consumption threshold and is greater than or equal to the second power consumption threshold. The reason for gradually increasing the value of the first operating parameter is to make the adjustment of the power consumption of the electronic device imperceptible to the user as much as possible, so as to ensure the user experience.

For example, the processor of the mobile phone issues the brightness level 3 of the screen brightness to the screen at the second time T2, the screen first increases the screen brightness from the brightness level 2 to the brightness level 3, then the processor of the mobile phone counts the actual total power consumption in the third time period T3, if the actual total power consumption in the third time period T3 is less than the second power consumption threshold, the processor of the mobile phone issues the brightness level 4 of the screen brightness to the screen at the third time T3, the screen first increases the screen brightness from the brightness level 3 to the brightness level 4, the processor of the mobile phone counts the actual total power consumption in the third time period T3, and if the actual total power consumption in the third time period T3 is less than the first power consumption threshold and greater than or equal to the second power consumption threshold, the increase of the screen brightness is stopped.

In a possible embodiment, if at least one system-on-chip includes a CPU, the electronic device reduces the first operating parameter from the second parameter value to the third parameter value, and if the third parameter value is a preset minimum value, acquires actual power consumption of the at least one system-on-chip and actual power consumption of the M peripheral devices in a fourth period, and calculates actual total power consumption of the electronic device in the fourth period, and if the actual total power consumption in the fourth period is greater than or equal to the first power consumption threshold, the electronic device reduces the power consumption of the system-on-chip in an order from low to high in priority of the system-on-chip, where the priority of the CPU is highest.

That is to say, after the electronic device reduces the values of the operating parameters of all the peripheral devices to the preset minimum value according to the power consumption control method, if the actual total power consumption in the next time period is still greater than the first power consumption threshold, the power consumption of each system-level chip is reduced according to the sequence from low to high of the priority of each system-level chip.

In a possible embodiment, if at least one system-on-chip includes a DDR, a GPU, and a CPU, and the priority of each system-on-chip is from low to high as the DDR, the GPU, and the CPU, the electronic device reduces the power consumption of each system-on-chip according to the priority of each system-on-chip from low to high. Because the priority of the CPU is highest, that is to say, the electronic device does not reduce the operating frequency of the CPU as much as possible, so as to ensure that the system performance of the electronic device is not obviously reduced.

It should be noted that, after the electronic device adjusts the operating frequency of the SOC according to the above method, if the actual total power consumption of the electronic device is determined to be far less than the second power consumption threshold in the next period, the operating frequency of the SOC is preferentially increased. Specifically, the electronic device may also increase the value of the operating frequency of the SOC multiple times according to the above method, and details are not repeated here.

The following describes in detail a power consumption control method of an electronic device according to an embodiment of the present application with reference to fig. 5, by taking the electronic device as a mobile phone and taking the mobile phone playing a video in a video application as an example.

Step 501, when the mobile phone plays a video, a temperature sensor of the mobile phone detects a current temperature of the electronic device, and a processor of the mobile phone determines a temperature threshold, a maximum power consumption budget and a minimum power consumption budget according to a current ambient light brightness, an operating state, a temperature rise rate, a current ambient temperature, a temperature of the electronic device, and the like.

Specifically, the mobile phone may determine in advance what scene the user is in according to the usage state of the mobile phone, for example, according to a user mode (e.g., an intelligent power saving mode), a charging state of the electronic device, an ambient light brightness value, a screen turning on/off condition, and the number of active applications of the mobile phone. And determining the temperature threshold value, the maximum power consumption budget and the minimum power consumption budget according to the identification result, and generating a corresponding relation table between the temperature threshold value and the maximum power consumption budget as well as the minimum power consumption budget. And then the mobile phone can search the corresponding relation table according to the current temperature of the electronic equipment so as to determine the corresponding temperature threshold value, the maximum power consumption budget and the minimum power consumption budget.

Step 502, if the current temperature of the electronic device is greater than the temperature threshold value, the processor of the mobile phone collects the actual power consumption values of the SOC and the peripheral device in the first regulation and control period in real time, and calculates the actual total power consumption of the mobile phone in the first regulation and control period.

Specifically, the mobile phone collects power consumption values of the SOC and the peripheral device for a plurality of times in the first regulation and control period T0, and collects power consumption values of each SOC and peripheral device in a fixed statistical period each time. And then summing the multiple power consumption values of each device to obtain the total power consumption of the device in a regulation period T0, and finally summing the power consumption of all peripheral devices and the power consumption of the SOC to obtain the total power consumption of the electronic equipment in the regulation period T0.

For example, as shown in fig. 6, assuming that a regulation and control period T0 is 50ms, and a statistical period T is 5ms, the statistical module performs statistics on power consumption of each SOC and peripheral device in a statistical period 5ms every 5ms, for 5 times in total. Suppose that the power consumptions of the CPU at t (1), t (2), t (3), t (4), t (5) are denoted by p1(1), p1(2), p1(3), p1(4) and p1(5), respectively, the power consumptions of the GPU at t (1), t (2), t (3), t (4), t (5) are denoted by p2(1), p2(2), p2(3), p2(4) and p2(5), the power consumptions of the screen at t (1), t (2), t (3), t (4), t (5) are denoted by p3(1), p3(2), p3(3), p3(4) and p3(5), and the power consumptions of the speaker at t (1), t (2), t (3), t (4), t (5) are denoted by p4(1), p4(2), p 4), p4 (26) and p4, respectively. Then the CPU, GPU, screen, speaker, within t (1), total power consumption c (1) ═ Σ (p1(1), p2(1), p3(1), p4(1), p5(1)), and so on, the CPU, GPU, screen, speaker, within t (2), total power consumption c (2) ═ Σ (p1(2), p2(2), p3(2), p4(2), p5(2)), the CPU, GPU, screen, speaker, within t (3), total power consumption c (3) ∑ (p1(3), p2(3), p3(3), p4(3), p5(3)), the CPU, GPU, screen, speaker, within t (4), total power consumption c (4) ═ 1(4), p2(4), p3(4), p4(4), p 24 (4), p 595 (p 595), p 595) (p 595), and p 595), p4(5), p5 (5)).

Based on the above statistical results, the final total power consumption value P1 of the CPU, GPU, screen, and speaker within the regulation period 50ms is ═ Σ (c (1), c (1), c (2), c (3), c (4), and c (5)).

Step 503, the processor of the mobile phone compares whether the actual total power consumption of the SOC and the peripheral device in the first regulation and control period is lower than a preset maximum power consumption budget, if so, step 504 is executed, otherwise, step 505 is executed.

In step 504, the processor does not adjust the power consumption of the peripheral device and the SOC device.

And 505, reducing the power consumption budgets of all the peripheral devices by the processor in n continuous regulation and control periods, and sending the parameter values of the working parameters corresponding to the reduced power consumption budgets to the corresponding peripheral devices.

Specifically, in the embodiment of the present application, the processor may reduce the power consumption budget of each peripheral device for multiple times in multiple regulation and control cycles. Continuing with the above example, for example, when the total actual power consumption value P1 of the CPU, the GPU, the screen, and the speaker in the first regulation period 50ms is greater than the maximum power consumption budget, the processor decreases the values of the power operating parameters of the screen and the speaker in the second regulation period, further, counts the total actual power consumption value P1 of the CPU, the GPU, the screen, and the speaker in the second regulation period 50ms, and if P1 is still greater than the maximum power consumption budget, the processor continues to decrease the operating parameters of the peripheral device for multiple times in the third regulation period. The power consumption of the mobile phone is adjusted in a control period, so that the adjustment of the power consumption of the mobile phone is not sensed by a user, the performance stability of the mobile phone in the control period is guaranteed, and the use experience of the user is guaranteed.

Step 506, the processor of the mobile phone collects the actual power consumption of the SOC and the peripheral device in the (n + 1) th regulation and control period in real time, and calculates the actual total power consumption of the mobile phone in the (n + 1) th regulation and control period.

And 507, stopping adjusting the power consumption of the peripheral device when the actual total power consumption of the mobile phone in the (n + 1) th regulation and control period is lower than the preset maximum power consumption budget.

Step 508, when the actual total power consumption of the mobile phone in the (n + 1) th regulation and control period is lower than the preset minimum power consumption budget, increasing the power consumption budgets of all the peripheral devices in a plurality of subsequent regulation and control periods, and sending the values of the working parameters corresponding to the increased power consumption budgets to the corresponding peripheral devices.

Step 509, when the actual total power consumption of the mobile phone in the (n + 1) th regulation and control period is still greater than the preset maximum power consumption budget and the values of the working parameters of all the peripheral devices are adjusted to the minimum value, the SOC except the CPU is reduced in frequency step by step.

Specifically, the mobile phone reduces the power consumption of each system-on-chip according to the priority of each system-on-chip from low to high. The priority of each system-level chip can be DDR, GPU and CPU from low to high. Because the priority of the CPU is highest, that is to say, the electronic device does not reduce the operating frequency of the CPU as much as possible, so as to ensure that the system performance of the electronic device is not obviously reduced.

Therefore, in the embodiment of the application, when the actual power consumption is lower than the minimum power consumption budget, the processor can control the system power consumption not to be lower than the minimum rated power consumption under the condition that the system power consumption is not higher than the rated maximum power consumption budget, so as to achieve the purpose of improving the performance of the mobile phone.

Illustratively, assume that the total power consumption statistical curve of the handset during playing video is shown in fig. 7. It can be seen from the figure that the power consumption of the mobile phone is changed frequently during the process of playing the video, and if the operating frequency of the CPU is directly reduced to a set threshold value in a place with the strongest demand, the video playing may be jammed. Therefore, in the embodiment of the present application, for the waveform shown in the interval a, that is, when the actual total power consumption of the mobile phone far exceeds the maximum power consumption budget 2600 mw, the mobile phone sends the values of the operating parameters to the screen and the speaker, the display screen reduces the brightness of the display screen, and the speaker reduces the volume of the speaker, so as to reduce the heat generation of the peripheral devices of the mobile phone. After the adjustment, the total power consumption of the mobile phone is basically controlled between 1800 milliwatts and 2600 milliwatts, and the working frequency of the SOC is not changed, so that the image quality definition and the fluency during video playing are ensured. For the waveform shown in the interval B, if the actual total power consumption of the mobile phone is far lower than the minimum power consumption of 500 milliwatt-hour, the values of the working parameters are sent to the screen and the loudspeaker, the display screen increases the brightness of the display screen, and the loudspeaker increases the volume of the loudspeaker. Therefore, the power consumption of the mobile phone does not exceed the maximum power consumption budget, and the performance of peripheral devices of the mobile phone can be improved.

Further, if the temperature of the mobile phone is still gradually increased after all the peripheral devices of the mobile phone are adjusted, and the actual total power consumption of the mobile phone still exceeds the maximum power consumption budget, the operating frequency of the SOC outside the CPU can be reduced to ensure the operating frequency of the CPU, and prevent the problems of stutter, slow refresh rate, and the like.

The embodiment of the application provides a power consumption control device of an electronic device, which can be obtained by improving the existing IPA and can be integrated in the electronic device. The device is mainly used for collecting the power consumption of each SOC and each peripheral device in each regulation and control period in real time, then adjusting the power consumption budget of each peripheral device in the next regulation and control period according to the maximum power consumption budget, and issuing an instruction to each peripheral device, wherein the instruction comprises an adjustment strategy corresponding to the adjusted power consumption budget. For example, the adjustment strategy can be strategies of reducing the brightness of a display screen, reducing the volume of a loudspeaker, reducing the power of a WiFi device, reducing the transmission power of a wireless Modem and the like. The device achieves the purpose of not reducing the power consumption budget of the SOC as far as possible by reducing the power consumption budget of the peripheral devices, thereby avoiding the occurrence of SOC frequency reduction or frequency limitation, realizing good temperature control effect and ensuring the system performance.

And the transceiver module 804 is configured to send the adjusted values of the operating parameters to each peripheral device. The transceiver module 804 in fig. 8 may be implemented by a communication interface between the processor 110 and the peripheral device in fig. 2.

Illustratively, when the temperature control module 801 detects that the current temperature of the electronic equipment is 65 degrees, the maximum power consumption budget value PL0 corresponding to the current temperature is determined, the acquisition module 802 acquires the SOC in the mobile phone and the total power consumption P1 of the peripheral devices in the previous control cycle, and then the processing module 803 calculates the actual total power consumption P1 of the equipment and then compares the P1 with the PL 0. When P1 is greater than PL0, the processing module 803 issues the value of the operating parameter in the next statistical cycle to each peripheral device through the transceiving module 804. Then, the acquisition module 802 continues to detect whether the actual total power consumption in the next statistical period is lower than the maximum power consumption budget value PL0, and if not, continues to issue the value of the working parameter until the actual total power consumption is lower than the maximum power consumption budget value PL 0.
