Description
Technical Field
The present disclosure relates to the field of semiconductor technologies, and in particular, to a method, an apparatus, a device, and a storage medium for speed regulation of a fan based on chip power consumption.
Background
In the heat dissipation design of high power consumption electronic equipment, PID (proportional-integral-derivative) speed regulation is a common fan regulation strategy. The rotating speed of the fan is controlled by adjusting three parameters of proportion (P), integral (I) and derivative (D), so as to achieve the purpose of controlling the temperature of equipment. The PID speed regulation can dynamically regulate the rotating speed of the fan according to the actual temperature of the equipment and the preset target temperature so as to keep the temperature of the equipment stable. Taking a high-power consumption CPU of a server as an example, the temperature control of the CPU is a key in heat dissipation design due to the large power consumption. In the conventional PID regulation strategy, kp (proportional gain) is usually set to be large in order to prevent the CPU from rapidly rising in temperature when switching from no load directly to full load. By doing so, the fan can be ensured to rapidly speed up when the power consumption of the CPU suddenly increases, thereby preventing the CPU from overheating and overtemperature. However, in the case of CPU power consumption fluctuation, the conventional PID regulation strategy is very sensitive to the variation of CPU power consumption due to the large Kp value, which causes the fan speed to oscillate periodically. The vibration not only can cause the noise of the fan to be suddenly high or low and influence the user experience, but also accelerates the abrasion of the fan and reduces the service life of the fan. More importantly, the periodic oscillation of the fan speed causes unstable control of the CPU temperature and even risk of CPU over-temperature. Therefore, to solve this problem, there is a need to improve the conventional PID throttling strategy so that it can better cope with the CPU power consumption fluctuation.

The embodiment of the application provides a fan speed regulating method, device and equipment based on chip power consumption and a storage medium.

The fan speed regulation method based on chip power consumption is applied to the computer equipment 500 in fig. 5.
Fig. 1 is a flow chart of a fan speed regulation method based on chip power consumption according to an embodiment of the present application. As shown in fig. 1, the method includes the following steps S110 to S150.
S110, converting the acquired temperature analog signals extracted from the current temperature information of the chip to be cooled into chip temperature data of digital signals.
S120, analyzing the temperature analog signals to obtain current power consumption information of the chip to be cooled, and converting the power consumption analog signals extracted from the current power consumption information into chip power consumption data of digital signals.
S130, analyzing the chip temperature data and the chip power consumption data according to a preset fan rotating speed regulation strategy to obtain chip temperature prediction information.
And S140, checking the chip temperature prediction information according to a preset chip power consumption judgment strategy and generating comparison check result information.
If the temperature value to be regulated belongs to the chip overtemperature state, generating a fan rotating speed regulating instruction which is a wind speed regulating instruction; if the temperature value to be regulated belongs to the chip self-adaptive state, judging that the fan rotating speed regulating instruction is a wind speed regulating instruction.
And S150, adjusting the control intensity coefficient according to a fan rotating speed adjusting instruction in the comparison and verification result information so as to calculate the designated rotating speed to control the cooling fan to rotate.
In the actual operation of the server, the power consumption of the CPU fluctuates due to the load variation. In order to effectively manage heat dissipation, the rotation speed of the fan needs to be dynamically adjusted according to the change of the CPU power consumption. This adjustment is typically accomplished by a tuning parameter such as the scaling factor Kp, the control intensity factor disclosed in the present method embodiment. This proportionality coefficient Kp determines the relationship between fan speed and CPU temperature or power consumption variation. The strategy of dynamically switching the speed regulation parameter can be regarded as a feedback control mechanism, which adjusts the control parameter (proportionality coefficient Kp) according to the current state of the system (CPU power consumption change) to achieve the best cooling effect and energy efficiency. In practice, this strategy may involve more complex algorithms, such as using a PID controller (proportional-integral-derivative controller) to dynamically adjust the Kp value to more precisely control the fan speed. The PID controller can comprehensively adjust the Kp value according to the rate of change (proportion) of the CPU temperature, the cumulative amount of temperature change (integral), and the trend of change (derivative). In summary, dynamically switching the speed regulation parameter is a strategy to optimize fan speed based on CPU power consumption changes, which helps the server to manage heat dissipation more efficiently while conserving energy and reducing noise.
In the specific implementation process, the method generates heat when the chip works, and cooling equipment such as a fan is needed to dissipate the heat. In order to ensure the normal operation of the chip and prolong the service life of the chip, the temperature and the power consumption of the chip need to be monitored in real time, and the rotating speed of the fan needs to be adjusted in time, so that the chip is kept in a safe operating temperature range. And extracting a temperature analog signal from the acquired current temperature information of the chip to be cooled, and converting the temperature analog signal into a digital signal to form chip temperature data. This step is an analog signal digitizing process that provides a standardized data format for subsequent processing. For example, an analog signal may be converted into a digital signal by an ADC (analog-to-digital converter). And analyzing the temperature analog signal to obtain the current power consumption information of the chip to be cooled, and then converting the power consumption analog signal into a digital signal to form chip power consumption data. This step is similar to the first step, but concerns about power consumption information, as well as the need for digitizing. For example, the power consumption data of the chip can be obtained by analyzing the power consumption analog signal. And analyzing the chip temperature data and the power consumption data to be converted by using a preset fan rotating speed regulating strategy. The strategy comprises a calculation formula generated based on a preset control intensity coefficient, and relates to a certain algorithm or mathematical model for predicting the future temperature change of the chip. For example, a temperature prediction model can be used to predict the temperature change of the chip in a future period of time according to the current temperature and power consumption data. And checking the chip temperature information to be predicted by adopting a preset chip power consumption judging strategy, and generating comparison checking result information. This step includes a threshold value for verifying the amplitude of the power consumption variation to determine whether the chip is in an over-temperature or adaptive state. According to different states, generating a command for adjusting the rotating speed of the fan, and adjusting the wind speed to be high or low. For example, if the predicted chip temperature exceeds a set over-temperature threshold, then an instruction to increase wind speed is generated; if the predicted chip temperature is within the adaptive range, then an instruction to lower wind speed is generated. The adjusted control intensity coefficient is used to calculate a specified rotational speed value that is used to control the rotation of the cooling fan to maintain the optimum operating temperature of the chip. For example, if the adjustment command is that the wind speed is increased, the control intensity coefficient is increased, so that the rotation speed of the fan is increased to increase the heat dissipation effect; if the adjustment command is a wind speed adjustment down, the control intensity coefficient is reduced, so that the rotation speed of the fan is reduced to reduce the heat dissipation effect.
In summary, the method solves the problem of fan rotation speed oscillation caused by chip power consumption change by dynamically adjusting the proportionality coefficient Kp of the PID controller. The strategy has the bright point that the control parameters can be flexibly adjusted according to the power consumption variation, so that the fluctuation of the rotating speed of the fan is reduced, and the risks of server noise and chip overheating are reduced. The system continuously monitors the power consumption of the CPU and calculates the amount of change between two consecutive power consumption readings. And according to the power consumption variation, the system dynamically adjusts the proportionality coefficient Kp of the PID controller. If the amount of power consumption variation is small, it means that the temperature variation of the chip is also small, so that the Kp value can be reduced to reduce the fluctuation of the fan rotation speed. In contrast, if the amount of change in power consumption is large, indicating that the temperature change of the chip is large, it is necessary to increase the Kp value at this time to ensure sufficient heat dissipation capability. In order to ensure that measures can be taken immediately when the chip temperature is too high, judgment logic of a high-temperature protection point is integrated in the system. When the chip temperature approaches or reaches a preset high temperature protection point, the system automatically switches to a corresponding Fan table, which contains preset values for the Fan speed under high temperature conditions. And calculating proper fan rotating speed according to the adjusted Kp value system, and sending a rotating speed adjusting instruction through a fan control interface so as to control the rotating speed of the fan. The method has the advantages that the fan rotating speed can be controlled more finely, unnecessary fluctuation is reduced, and therefore the energy efficiency and the reliability of the server are improved. Meanwhile, by integrating the high-temperature protection point judgment logic, the method can also ensure that actions can be rapidly taken when the temperature of the chip is too high, so that the chip is prevented from being damaged. In a word, the method provides an efficient and intelligent fan rotating speed control strategy by dynamically switching the PID proportion coefficient Kp and integrating the high-temperature protection point judgment logic, is suitable for various server working scenes, and is beneficial to improving the overall performance and reliability of the server.
By monitoring the temperature and power consumption data of the chip in real time, the system can quickly respond to the thermal load change of the chip, and timely adjustment of heat dissipation measures is ensured. Based on the analysis of the temperature and power consumption data, the system can generate an accurate fan rotation speed adjustment instruction to adapt to the thermal load change of the chip, thereby improving the heat dissipation efficiency. Through dynamic adjustment of the rotating speed of the fan, the system can optimize the heat dissipation performance according to the actual demands of the chip, and the situation of excessive cooling or insufficient heat dissipation is avoided. Through intelligent control fan rotational speed, the system can reduce the energy consumption when guaranteeing the heat dispersion, improves the whole energy efficiency of server. By avoiding frequent or severe fan speed changes, the system can reduce noise and vibration of the server, improve the stability and reliability of operation of the server, and fundamentally solve the problem of periodic oscillation of the chip cooling fan speed. According to the temperature state and the power consumption change of the chip, the rotating speed of the fan is automatically adjusted, so that self-adaptive temperature management is realized, and the chip is ensured to run in a safe and optimal working temperature range.
In a more specific embodiment, as shown in FIG. 2, performing step S130 further specifically includes performing steps S131-S134.
S131, carrying out statistical calculation on chip temperature data according to a temperature change statistical strategy in a fan rotating speed regulating strategy so as to obtain a chip temperature change rate in a preset statistical duration; s132, calculating chip power consumption data according to a chip power consumption calculation strategy in a fan rotating speed adjustment strategy to obtain a chip power consumption change rate based on a statistic duration; s133, performing fitting calculation based on the chip temperature change rate and the chip power consumption change rate to obtain a temperature-power consumption correlation curve; s134, predicting the chip temperature change trend according to the temperature-power consumption correlation curve so as to generate chip temperature prediction information.
Specifically, in a more specific embodiment, the chip temperature data is statistically analyzed according to a temperature variation statistical strategy in the fan speed adjustment strategy. This includes calculating a rate of change of core temperature over a preset statistical period of time. For example, the rate of change of temperature per minute or per second may be calculated to understand the trend and speed of temperature change. And calculating the chip power consumption data according to the chip power consumption calculation strategy in the fan rotating speed regulation strategy. This involves calculating the rate of change of chip power consumption over a statistical period of time. Similar to the rate of temperature change, the rate of power consumption may help to understand fluctuations in power consumption. And carrying out fitting calculation based on the chip temperature change rate and the chip power consumption change rate to obtain a temperature-power consumption correlation curve. This curve may reflect the relationship between temperature and power consumption, e.g. how the temperature changes as the power consumption increases. Fitting may be performed by various mathematical methods, such as linear regression, polynomial regression, or nonlinear regression. And predicting the temperature change trend of the chip according to the temperature-power consumption correlation curve to generate chip temperature prediction information. This may be done by integrating the temperature-power consumption correlation curve to predict future temperature values, or using more complex prediction models such as time series analysis, machine learning, etc. Through these steps, the system can more accurately predict the temperature change of the chip and adjust the fan speed according to the predictions, so as to realize more effective heat dissipation and energy management. The method can reduce the rotation speed oscillation of the fan caused by temperature fluctuation and improve the stability and energy efficiency of the server.
In a more specific embodiment, as shown in FIG. 3, performing step S140 further comprises performing steps S141-S142.
S141, calculating to obtain the maximum amplitude value of the chip power consumption change in the chip temperature prediction information according to the power consumption calculation strategy in the chip power consumption judgment strategy; s142, judging whether the maximum amplitude value exceeds a power consumption variation amplitude threshold value; if the maximum amplitude value exceeds the power consumption variation amplitude threshold, step S1421 is executed to generate a corresponding fan rotation speed adjustment instruction as comparison verification result information according to the fan rotation speed adjustment strategy.
Specifically, in a more specific embodiment, the execution of step S140 is further refined as follows: and calculating the maximum amplitude value of the chip power consumption change in the chip temperature prediction information according to the power consumption calculation strategy in the chip power consumption judgment strategy. This value may be the maximum power consumption variation in the predicted period of time, reflecting the severity of the power consumption fluctuation. And judging whether the calculated maximum amplitude value exceeds a preset power consumption variation amplitude threshold value. This threshold is a critical point beyond which it may mean that more aggressive heat dissipation measures need to be taken. If the maximum amplitude exceeds the power consumption variation amplitude threshold, which indicates that the power consumption of the chip fluctuates greatly, the fan rotation speed may need to be adjusted to adapt to the variation. Thus, step S1421 is performed: and generating a corresponding fan rotating speed adjusting instruction according to the fan rotating speed adjusting strategy. These instructions will be used to adjust the rotational speed of the fan to provide the proper heat dissipation capability to cope with the large fluctuations in power consumption. Through the steps, the system can monitor the power consumption change of the chip in real time, and adjust the rotating speed of the fan according to the change amplitude, so that the chip is ensured not to be overheated or overcooled due to power consumption fluctuation. This dynamic adjustment strategy helps to improve the energy efficiency and reliability of the server while reducing noise and energy consumption.
In a more specific embodiment, performing step S1421 further comprises performing steps S1422-S1425. S1422, carrying out numerical screening on the chip temperature data according to a temperature-rotating speed matching strategy in the fan rotating speed adjusting strategy to obtain a temperature value to be adjusted; s1423, setting the chip temperature state type into a chip overtemperature state and a chip self-adaptive state according to the temperature value change amplitude in the chip temperature prediction information; s1424, judging a temperature value to be regulated according to a rotational speed customization strategy in the fan rotational speed regulation strategy so as to determine an instruction type; s1425, generating a corresponding fan rotating speed adjusting instruction as comparison verification result information according to the instruction type.
Specifically, in a more specific embodiment, the execution of step S1421 is further refined as follows: and carrying out numerical screening on the chip temperature data according to a temperature-rotating speed matching strategy in the fan rotating speed adjusting strategy to obtain a temperature value to be adjusted. This step may involve determining whether the current temperature needs to be adjusted, and the adjusted target temperature. And setting the chip temperature state type as a chip over-temperature state or a chip self-adaptive state according to the temperature value variation amplitude in the chip temperature prediction information. An over-temperature condition may require immediate action to reduce the temperature, while an adaptive condition may allow for some temperature fluctuation. And judging the temperature value to be regulated according to a rotational speed customization strategy in the fan rotational speed regulation strategy so as to determine the instruction type. This may involve determining whether to increase or decrease the fan speed based on the current temperature and a preset speed profile. And generating a corresponding fan rotating speed adjusting instruction according to the instruction type. These instructions will be used to adjust the rotational speed of the fan to provide proper heat dissipation capability in response to large fluctuations in power consumption or abnormal changes in temperature. Through these steps, the system can control the fan speed more finely to adapt to the change of the chip temperature, ensure that the chip operates in a safe and effective temperature range. This strategy helps to improve the energy efficiency and reliability of the server while reducing noise and energy consumption.
More specifically, performing step S150 includes performing steps S151-S152.
S151, if the fan rotation speed adjusting instruction is a lowering instruction, lowering the control intensity coefficient; and S152, if the fan rotating speed adjusting instruction is an increasing instruction, increasing the control intensity coefficient.
Specifically, in a more specific embodiment, performing step S150 involves adjusting the control intensity coefficient according to a fan speed adjustment command. This step can be further refined into the following two sub-steps: if the fan speed adjustment command indicates a reduced speed, the system adjusts the control intensity coefficient down. The control intensity coefficient may be associated with an adjustment amplitude of the fan speed, and decreasing the coefficient means decreasing the adjustment amount of the fan speed to avoid excessive cooling or in response to a decrease in power consumption. If the fan speed adjustment command indicates an increase in speed, the system will control the intensity factor to be increased. This typically occurs when the power consumption of the chip increases or the temperature increases, requiring an increase in fan speed to provide additional heat dissipation capability. The control intensity coefficient is increased to ensure that the adjustment of the rotating speed of the fan can timely respond to the change of temperature or power consumption. Through these steps, the system can adjust the fan speed according to the actual heat dissipation demand, thereby optimizing the heat dissipation performance of the server while taking into account energy efficiency and noise control. The dynamic adjustment strategy is helpful for ensuring that the chip operates in a safe and effective temperature range, and improving the reliability and energy efficiency of the server.
