In order to explain the technical solution of the present application, the following description is given by way of specific examples.
Referring to fig. 1, a first flowchart of a server fan speed regulation method provided in an embodiment of the present application is shown, and as shown in fig. 1, a server fan speed regulation method includes the following steps:
In the server, each target device has an ideal temperature value of the target device, and when each target device operates at the ideal temperature of the target device, the service life of the target device can be prolonged, and the service life of the server can be prolonged.
The target device may refer to a key device in the server, the key device refers to a more important device in the server, such as a power supply, a processor, a hard disk, and the like, the target device may be selected from a plurality of key devices in the server according to different application scenarios, and the specific type of the target device is not limited in the present application.
In this embodiment, the ideal temperature value of each target device in the server may be formulated by the user according to the optimal operating performance of the target device, and taking the target device as the processor as an example, if the operating performance of the processor is optimal when the processor operates at 60 degrees (the operating performance includes the operating speed and the operating frequency, etc.), the user may directly set the ideal temperature value of the processor to be 60 degrees. The actual temperature value of each target device in the server can be acquired by additionally installing a temperature sensor on each target device.
In one possible embodiment, obtaining the desired temperature value for each target device comprises:
obtaining the rated temperature of each target device and the weight value corresponding to each target device;
and taking the product of the rated temperature and the weighted value of each target device as an ideal temperature value of each target device.
Wherein, the rated temperature of each target device may refer to the highest temperature at which the target device can operate for a long time. The weight value corresponding to each target device can be set according to the importance degree of the target device in the server, the value range of the weight value can be [0,1], wherein the smaller the weight value is, the higher the importance degree of the target device in the server is represented.
In this embodiment, the ideal temperature value of each target device may be obtained according to the importance degree of the target device in the server and the maximum temperature at which the target device can operate for a long time, and the ideal temperature value of the target device may be obtained by multiplying the maximum temperature at which the target device can operate for a long time by the importance degree of the target device in the server.
For example, for a processor in the server, the processor is responsible for the calculation and control of the whole server in the server and is the most core component affecting the performance of the server, so the weight value corresponding to the processor can be set to be 0.8, and since the maximum temperature at which the processor can operate for a long time is 80, an ideal temperature value of the processor can be obtained to be 64 degrees.
It should be understood that the weighted value in the embodiment of the present application may be set according to the importance level of the target device in the server, and the importance level of each target device is different in different application scenarios. For example, when playing a game, the running speed of the processor is more important, and the performance of the graphics card is lower than that of the processor, and at this time, the weight value of the processor may be set to be smaller than that of the graphics card; when the server is used for watching videos, the display performance of the display card is more important, the running speed of the processor is lower than the display performance of the display card in importance, and the weight value of the display card can be set to be smaller than that of the processor. In general, the user can adaptively adjust the weight value of each target device according to different application scenarios.
And 102, calculating a difference value between the ideal temperature value and the actual temperature value of each target device, and taking the minimum value in the difference value as an adjusting reference value for indicating the comprehensive temperature deviation of the server.
In the embodiment of the application, the difference between the ideal temperature value and the actual temperature value of each target device is a difference obtained by subtracting the actual temperature value from the ideal temperature value of each target device, and if the difference is a positive value, it indicates that the actual temperature value of each target device is smaller than the ideal temperature value, so that the operation requirement of the server is met, and the rotation speed of the system fan can be adjusted down according to the deviation. If the minimum value in the difference value is a negative value, it is indicated that the actual temperature value of the target device with the negative value is higher than the ideal temperature value of the target device, and the rotating speed of the system fan needs to be adjusted up according to the deviation to cool the target device, so that the actual temperature value of the target device can reach the ideal temperature value of the target device.
And taking the minimum value in the difference value as an adjusting reference value for indicating the comprehensive temperature deviation of the server, and performing down-regulation treatment on the rotating speed of the system fan to improve the temperature of the target device when the difference value is positive. The deviation between the actual temperature of the target device and the actual temperature value and the ideal temperature value of the target device is minimum (wherein, the deviation is obtained by taking a negative value for the difference value between the actual temperature value and the ideal temperature value of the target device), and the minimum deviation value is used as an adjusting reference value for indicating the comprehensive temperature deviation of the server, so that the actual temperature values of other target devices can be less than or equal to the ideal temperature values of the other target devices after the rotating speed of the server is adjusted downwards.
And when the difference is negative, the rotating speed of the system fan is adjusted upwards to reduce the temperature of the target device. The deviation between the actual temperature value and the ideal temperature value of the target device is the largest (wherein, the deviation is obtained by taking a negative value for the difference value between the actual temperature value and the ideal temperature value of the target device), and the maximum deviation value is used as an adjusting reference value for indicating the comprehensive temperature deviation of the server, so that the actual temperature values of other target devices in the server can be ensured to be less than or equal to the ideal temperature value of the server.
In this embodiment, the server integrated temperature deviation may refer to a difference between a server integrated temperature and a server integrated temperature threshold, and the server integrated temperature may be specifically represented by the following formula:
keyT＝Taim-Min((Ar·Tah-Ta)，(Br·Tbh-Tb)，(Cr·Tch-Tc)…)
wherein, keyT refers to the comprehensive temperature of the server; taim refers to a server aggregate temperature threshold, with a target value that can be understood to be a server aggregate temperature; ar, Br and Cr respectively refer to weight values corresponding to the device A, the device B and the device C; tah, Tbh and Tch respectively refer to rated temperatures of the device A, the device B and the device C; ta, Tb and Tc respectively refer to the actual temperature values of the device A, the device B and the device C; min (a, b, c) is the minimum value of a, b, c.
The comprehensive temperature deviation of the server can be obtained by the formula as follows:
e(n)＝keyT(n)-Taim
＝-Min((Ar·Tah-Ta(n)),(Br·Tbh-Tb(n)),(Cr·Tch-Tc(n))…)
wherein e (n) is the comprehensive temperature deviation of the server at the nth time, and n is the nth time; ta (n), Tb (n), Tc (n) are actual temperature values of the device A, the device B and the device C at the nth time respectively.
It should be understood that the server integrated temperature is an integrated temperature corresponding to all target devices in the server, and the server integrated temperature threshold is an ideal value of the server integrated temperature, where the server integrated temperature threshold may be obtained based on a weight value of each target device, and may be set by a user according to an ideal temperature value of each target device, and the size of the server integrated temperature threshold is not limited in the present application.
And 103, controlling the fan to operate based on the adjusting reference value.
In the embodiment of the present application, the adjustment reference value indicates the server integrated temperature deviation, and the control of the fan operation based on the adjustment reference value indicates adjusting the integrated temperature deviation so that the server integrated temperature approaches the server integrated temperature threshold, and outputting the fan control signal to control the fan operation when the adjusted integrated temperature deviation enables the server integrated temperature to approach the server integrated temperature threshold.
In one possible embodiment, controlling the fan operation based on the adjustment reference value includes:
when the adjusting reference value is a negative value in the difference value between the ideal temperature value and the actual temperature value of each target device, adjusting the current rotating speed of the fan to the target fan rotating speed based on the adjusting reference value;
the fan operation is controlled based on the target fan speed.
In the embodiment of the present application, when the adjustment reference value is a negative value of the difference between the ideal temperature value and the actual temperature value of each target device, it can be determined that the actual temperature value of a target device is greater than the ideal temperature value of the target device in all target devices. Because the adjustment reference value is the minimum difference value in the difference values between the ideal temperature value and the actual temperature value of each target device, if the minimum difference value is a negative value, it indicates that the target device corresponding to the minimum difference value is the target device with the largest difference between the actual temperature value and the ideal temperature value, and therefore, the rotation speed of the fan should be adjusted based on the adjustment reference value, the current rotation speed of the fan is adjusted to the target rotation speed of the fan, and the operation of the fan is controlled based on the target rotation speed of the fan.
It should be understood that the target fan speed may be such that the actual temperature value of the target device corresponding to the minimum difference is less than or equal to its own desired temperature value.
In one possible embodiment, adjusting the current rotation speed of the fan to the target fan rotation speed based on the adjustment reference value includes:
taking the negative value of the adjusting reference value;
obtaining a fan control signal through a PID control algorithm based on the negative value of the regulation reference value;
and controlling the fan to adjust the current rotating speed to the target rotating speed of the fan according to the fan control signal.
In the embodiment of the present application, since the server integrated temperature deviation is a difference between the server integrated temperature and the server integrated temperature threshold, when the server integrated temperature is greater than the server integrated temperature threshold, it is determined that the server integrated temperature deviation is a positive value, and the adjustment reference value for indicating the server integrated temperature deviation is a negative value, the adjustment reference value should be first negatively adjusted to obtain a negative value of the adjustment reference value equal to the server integrated temperature deviation.
The PID control algorithm may adopt an incremental PID control algorithm, and a control formula of the incremental PID control algorithm may be represented by the following equation:
wherein u (n) refers to the fan speed at the nth time (i.e., the target fan speed), and u (n-1) refers to the fan speed at the nth-1 time; kp refers to the PID control algorithmThe coefficient of the scale term of (a),
refers to the integral term coefficient in the PID control algorithm,
the method refers to a differential term coefficient in a PID control algorithm; and e (n) is the comprehensive temperature deviation of the server at the nth time, e (n-1) is the comprehensive temperature deviation of the server at the nth-1 time, and e (n-2) is the comprehensive temperature deviation of the server at the nth-2 time.
And obtaining the target fan rotating speed of the fan according to the equation, and adjusting the current rotating speed of the fan to the target fan rotating speed according to the obtained fan control signal.
In one possible embodiment, controlling the fan to adjust from the current fan speed to the target fan speed according to the fan control signal comprises:
and adjusting the current rotating speed of the fan to the target rotating speed of the fan according to a duty ratio signal of PWM (Pulse Width Modulation).
In the embodiment of the application, the difference between the ideal temperature and the actual temperature of each target device can be obtained by obtaining the ideal temperature and the actual temperature of each target device, the minimum difference in the differences of the plurality of target devices is taken as an adjusting reference value for indicating the comprehensive temperature deviation of the server, the fan is controlled to operate based on the adjusting reference value, and the adjusting reference value for indicating the comprehensive temperature deviation of the server is obtained, so that compared with the temperature deviation of each device adjusted in the prior art, the method reduces the complexity of a speed regulation strategy, adjusts the operation of the fan based on the comprehensive temperature deviation of the server, and ensures the accuracy of the speed regulation method of the fan of the server.
Referring to fig. 2, a second flowchart of a server fan speed regulation method provided in an embodiment of the present application is shown, and as shown in fig. 2, a server fan speed regulation method includes the following steps:
And 203, when the adjusting reference value is a negative value in the difference value between the ideal temperature value and the actual temperature value of each target device, adjusting the current rotating speed of the fan to the target fan rotating speed based on the adjusting reference value, and controlling the fan to operate based on the target fan rotating speed.
The steps 201-203 of this embodiment are the same as the steps 101-103 of the previous embodiment, which can be referred to each other, and the description of this embodiment is omitted here.
And 204, when the adjusting reference value is a positive value in the difference value between the ideal temperature value and the actual temperature value of each target device, adjusting the current rotating speed of the fan to the target fan rotating speed based on the adjusting reference value, and controlling the fan to operate based on the target fan rotating speed.
In the embodiment of the present application, the adjustment reference value refers to a minimum value of a difference between an ideal temperature value and an actual temperature value of each target device, and if the minimum value is a positive value, it indicates that the actual temperature value of each target device is smaller than its own ideal temperature value.
It should be appreciated that when the actual temperature value of each target device is less than its own desired temperature value, then the fan may be controlled to turn down in an attempt to achieve lower power consumption and noise levels.
Exemplarily, it is assumed that the actual temperature values and ideal temperature values of the device a, the device B, and the device C in the server are shown in table 1, where the rated temperature of the device a is 85 degrees, and the corresponding weight value is 0.7; the rated temperature of the device B is 100 ℃, and the corresponding weight value is 0.65; the rated temperature of the device C is 105 ℃, and the corresponding weight value is 0.6; and the server integrated temperature threshold is set to 80, the following server integrated temperature and corresponding fan action can be obtained.
