Fig. 2 shows a flow of the power module control method of the present application.
The control method comprises the following steps:
S10, acquiring a trigger instruction for adjusting a working module, wherein the working modes comprise a mute mode, an over-frequency mode and an adaptive mode;
s20, adjusting output parameters of the power management module and cooling operation parameters of the cooling module according to the trigger instruction.
In step S10, the trigger instruction for adjusting the working module may be sent by a manner of inputting an instruction by a user, or may be automatically triggered by a system preset condition.
The mute mode is mainly used for low power consumption, such as a computer system in a standby state or a working state of low frequency low operation, such as simple word processing. At this time, the computer system has lower requirement for power input, and can reduce energy consumption and noise by adjusting to a mute mode.
The over-frequency mode is mainly used for high-power consumption working states such as a large number of operation processes, such as complex image processing, data analysis operation and the like, and the computer system needs high power consumption requirements at the moment, and the power supply requirements of the system can be ensured by adjusting the over-frequency mode.
The self-adaptive mode is an automatic adjustment working mode of the power supply module, and the output parameters of the power supply module are automatically adjusted according to a preset working model, so that the power supply module is maintained in an optimal working condition interval.
In the present application, the output parameters of the power management module may be output power, voltage, current, operating frequency, etc. The cooling operation parameter may be a fan speed, a circulation pump speed, etc.
In step S20, the adjusting, according to the trigger instruction, the output parameter of the power management module and the cooling operation parameter of the cooling module includes:
Outputting corresponding output parameters according to the working mode required by the trigger instruction;
obtaining an adjustment comparison table of output parameters and cooling operation parameters;
and correspondingly adjusting the cooling operation parameters of the cooling module based on the adjustment reference table according to the output parameters.
In the application, the output parameters of different intervals are defined to be matched with corresponding cooling operation parameters, so as to establish an adjustment comparison table of the output parameters and the cooling operation parameters.
For example, the output power in the power module output parameters and the fan speed in the cooling operation parameters may be selected to establish an adjustment map. The output power is divided into power intervals from small to large according to a certain proportion, and the corresponding fan rotating speed is set in each power interval.
Based on the adjustment reference table, the cooling operation parameters of the cooling module, such as the rotation speed of the cooling fan, can be correspondingly adjusted according to the output power to be adjusted or the monitored actual output power.
The speed of the cooling fan may be controlled at least by pulse width modulation. The speed control of the cooling fan includes: the cooling fan speed is stepped up or down to provide different levels of heat dissipation management.
In the present application, before or after correspondingly adjusting the cooling operation parameters of the cooling module based on the adjustment reference table, the method further includes: and acquiring the surface temperature of the power management module, and adjusting the cooling operation parameters of the cooling module according to the surface temperature.
The power management module can produce heat when the during operation, and when the heat reaches a certain value, can influence the working performance and the life of power management module components and parts.
The working environment temperature of the power management module can be improved by monitoring and acquiring the surface temperature of the power management module and then adjusting the cooling operation parameters of the cooling module according to the surface temperature, so that the dual improvement of the performance and the service life is achieved.
In some embodiments, the surface temperature of the power management module may be obtained before the cooling operation parameter of the cooling module is correspondingly adjusted based on the adjustment reference table, and when the surface temperature reaches the temperature required to start the cooling module or increase the cooling operation parameter, the cooling operation parameter is adjusted to ensure that the thermal environment of the power management module is in an ideal condition.
In other embodiments, the surface temperature of the power management module may be obtained after the cooling operation parameters of the cooling module are correspondingly adjusted based on the adjustment reference table, and when the surface temperature reaches the temperature required to start the cooling module or increase the cooling operation parameters, the cooling operation parameters are adjusted to further improve the thermal environment of the power management module.
In other embodiments, the surface temperature of the power management module may be obtained in real time and the cooling operation parameters may be adjusted before and after the cooling operation parameters of the cooling module are correspondingly adjusted based on the adjustment lookup table.
In order to match the multi-mode switching requirement of the power management module, the priority of correspondingly adjusting the cooling operation parameters of the cooling module based on the adjustment comparison table is higher than that of adjusting the cooling operation parameters of the cooling module according to the surface temperature. Namely, the cooling operation parameters of the cooling module are adjusted according to the working mode, then the surface temperature of the power management module is obtained, and the cooling operation parameters are adjusted.
In the application, the operation of acquiring the trigger instruction which is adjusted to the mute mode and adjusting the output parameter of the power management module and the cooling operation parameter of the cooling module according to the trigger instruction comprises the following steps:
acquiring a trigger instruction adjusted to a mute mode;
Controlling the power management module to provide output parameters in a first preset mode;
and controlling the cooling operation parameters of the cooling module to be in a stop operation state based on the adjustment comparison table.
Wherein the first preset mode includes limiting the output power of the power management module, and in particular, limiting the output power set by the power management module in a low power consumption manner.
At this time, the power management module is in a low-power-consumption working state, and the heating value is small, so that the cooling operation parameters of the cooling module are controlled to be in a stop operation state, and the effects of reducing power consumption and noise can be realized.
During the use, the actual work load of the computer system can be detected in real time or periodically, and when the actual work load exceeds a first load threshold value, the cooling module is started, and the cooling module is adjusted to work with a first operation parameter.
The first load threshold may be set to a power that reaches a proportion of the output power in the first preset mode, for example, 85% or more, at which time the power consumption of the computer system increases, so that the heating value of the power management module increases. At this time, the computer system may activate the cooling module to adjust the cooling module to operate with the first operating parameter to provide the heat dissipation cooling effect.
Still further, before or after the cooling module is operated at the first operating parameter, the method further comprises:
Acquiring the surface temperature of a power management module;
Judging whether the surface temperature exceeds a preset first temperature threshold, and if so, adjusting the cooling module to work with a second operation parameter larger than the first operation parameter;
And if the surface temperature is lower than the first temperature threshold value, adjusting the cooling module to work with the first operation parameter.
Through the operation, when the surface temperature exceeds the first temperature threshold, the cooling module is adjusted to work with the second operation parameter which is larger than the first operation parameter, and the operation parameter of the cooling module can be improved to provide enough heat dissipation and cooling effects. When the surface temperature is lower than the first temperature threshold, the cooling module is not required to be adjusted to work with the second operation parameter so as to maintain the low-noise low-power consumption state.
In the application, the operation of acquiring the trigger instruction which is adjusted to the over-frequency mode and adjusting the output parameter of the power management module and the cooling operation parameter of the cooling module according to the trigger instruction comprises the following steps:
acquiring a trigger instruction adjusted to an over-frequency mode;
Controlling the power management module to provide output parameters in a second preset mode;
Based on the adjustment map, the adjustment cooling module operates at a third operating parameter that is greater than the second operating parameter.
Wherein the second preset mode may comprise defining an output power and/or an operating frequency of the power management module. For example, the output power of the power management module is set to an over-frequency power higher than the rated power, or the operating frequency is set to an over-frequency power higher than the rated operating frequency, for example, the rated 60kHz is raised to 100kHz. By improving the output parameters of the power management module, higher working performance can be achieved for the computer system so as to meet high-power consumption working states such as a large number of operation processes, such as complex image processing, data analysis and operation, and the like.
When the power management module is in the over-frequency operation mode, the cooling module is adjusted to work with a third operation parameter which is larger than the second operation parameter, so that enough heat dissipation can be ensured. For example, the rotation speed of the cooling fan is increased to increase the amount of heat radiation air.
In the application, the operation of acquiring the trigger instruction adjusted to the self-adaptive mode and adjusting the output parameter of the power management module and the cooling operation parameter of the cooling module according to the trigger instruction comprises the following steps:
acquiring a trigger instruction adjusted to a self-adaptive mode;
acquiring a real-time work load, matching the real-time work load with a preset load model to obtain a real-time output parameter of the power management module, and regulating the real-time output of the power management module according to the real-time output parameter;
based on the adjustment map, the adjustment cooling module operates at a fourth operating parameter. The fourth operating parameter is intermediate between the first operating parameter and the third operating parameter.
When a user uses a computer system, different loads may be generated on the computer system according to different use modes during different periods. For example, a user may need to perform word processing, image processing, data analysis operations, etc. during the day, may be running games, playing video, etc. for entertainment use during the evening, and may have the computer system in a standby state during the rest. If the power management module maintains a fixed mode of operation, it may result in performance starvation or performance overstrain. If the user is required to adjust the working mode of the power module by himself, the operation is inconvenient.
The application sets the self-adaptive mode for the power supply module, can match the real-time output parameter of the power supply management module through the preset load model, and adjusts the operation parameter of the cooling module according to the real-time output parameter so as to realize self-adaptive adjustment.
Specifically, when the real-time workload changes, the fourth operation parameter is correspondingly adjusted according to the adjustment reference table, so that the self-adaptation of the cooling module is realized. Typically, the fourth operating parameter may be set between the first operating parameter and the third operating parameter because the daily use environment is less likely to enter the over-frequency operating mode.
In the application, the step of matching the actual work load with a preset load model to obtain the real-time output parameters of the power management module comprises the following steps:
Establishing a load model and storing;
the load model building step comprises the following steps: collecting the use data of the actual workload in a preset period; setting up a mapping table according to the use data and the time period in the period, and setting a plurality of matched workload trigger values and time trigger values; and setting real-time output parameters of the corresponding power management modules according to the workload trigger values, wherein the ratio of the workload trigger values to the real-time output parameters is 60% -80%.
The established load model can be stored in a memory, so that the call of the processor is facilitated.
When the real-time workload or the use time triggers a preset workload trigger value and a time trigger value, the power management module is adjusted to output corresponding real-time output parameters.
By way of example, usage data may be collected when a user uses the computer system daily, including in particular power consumption, program usage, etc. of the system in nodes of different time periods, for example, at 9 to 12 and 14 to 18, the computer system may be in use for word processing, web browsing, etc.; at 12 to 14 and 18 to 20, the computer system may be in a standby state; during the period 20 to 23 hours, the computer system may be in use for video play, running games. Different usage conditions at different time periods may produce different actual workloads.
Several matched workload trigger values and time trigger values can be set by collecting statistics on usage data over a period (e.g., one week, one month, etc.), and building a mapping table of usage data and time periods.
In some embodiments, the time periods may be divided, and the time trigger value may be set, so as to provide the real-time output parameters of the power management module corresponding to the different time periods. When the use time of the user triggers the corresponding set time trigger value, the power management module is adjusted to output the corresponding real-time output parameter, if the user uses the computer system at 9 am of the working day, the power management module is adjusted to output the corresponding real-time output parameter which accords with the preset working state (such as word processing and web browsing). .
In other embodiments, the mapping table may be established according to the combination of the actual workload and the time period, and if the workload trigger value and the time trigger value need to be triggered simultaneously, the corresponding real-time output parameters output by the power management module are correspondingly adjusted. Through the setting of simultaneous triggering, the power supply module can be matched with the actual use condition of the computer system, so that the power supply module can adjust the optimal working condition interval.
In the application, the ratio of the work load trigger value to the real-time output parameter is 60% -80%, so that the working condition interval of the power supply module is more matched with the actual work load, and the power supply module is in the optimal working condition interval.
The present application has at least one of the following advantages:
(1) The power module can have at least three working modes by the power module control method, and each working mode has matched cooling parameters, so that the power module in different working modes is ensured to have optimal use environments.
(2) The power supply module has a self-adjusting function of heat dissipation by setting the output parameters and matching output of the cooling module.
(3) By collecting the usual use habit setting mapping table of the user, the self-adaptive adjustment of the output of the power supply module is realized, the matching of the use load and the output parameter is achieved, and the power supply module is in the optimal working condition interval.
