In order to illustrate the technical scheme of the application, the following description is given by specific examples.
Referring to fig. 1, a flowchart of a method for adjusting speed of a server fan according to an embodiment of the present application is shown, and as shown in fig. 1, a method for adjusting speed of a server fan includes the following steps:
And step 101, acquiring an ideal temperature value and an actual temperature value of each target device in the server.
In the server, each target device has its own ideal temperature value, and when each target device operates at its own ideal temperature, the service life of the target device itself can be increased, and the service life of the server can be also increased.
The target device may refer to a key device in the server, the key device refers to a relatively 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 by the present application.
In the embodiment of the present application, the ideal temperature value of each target device in the server may be formulated by the user according to the optimal operation performance of the target device, taking the target device as the processor as an example, if the operation performance of the processor is optimal (the operation performance includes the operation speed and the operation frequency) when the processor operates at 60 degrees, the user may directly set the ideal temperature value of the processor to 60 degrees. And the actual temperature value of each target device in the server can be provided with a temperature sensor on each target device so as to acquire the actual temperature value of each target device.
In one possible implementation, obtaining the desired temperature value for each target device includes:
acquiring the rated temperature of each target device and the weight value corresponding to each target device;
The product of the rated temperature and the weight value of each target device is taken 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 is capable of long-term operation. The weight value corresponding to each target device can be set according to the importance degree of the target device in the server, and the weight value can be in the range of 0 and 1, wherein the smaller the weight value is, the higher the importance degree of the target device in the server is.
In the embodiment of the application, the ideal temperature value of each target device can be obtained according to the importance degree of the target device in the server and the highest temperature of the target device capable of operating for a long time, and the ideal temperature value of the target device can be obtained by multiplying the highest temperature of the target device capable of operating for a long time with the importance degree of the target device in the server.
For example, for the processor in the server, the processor is responsible for the operation 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 the ideal temperature value of the processor can be obtained to be 64 degrees because the highest temperature of the processor capable of running for a long time is 80 degrees.
It should be understood that, in the embodiment of the present application, the weight value may be set according to the importance degree of the target device in the server, and in different application scenarios, the importance degree of each target device is different. For example, when playing a game, the running speed of the processor is more important, and the performance of the display card is lower in importance than the running speed of the processor, and the weight value of the processor can be set to be smaller than that of the display card; when the server is used for watching the video, the display performance of the display card is more important, and the running speed of the processor is lower than the display performance of the display card, so that the weight value of the display card can be set smaller than the weight value of the processor. In general, the user can adaptively adjust the weight value of each target device according to different application scenarios.
Step 102, calculating the difference between the ideal temperature value and the actual temperature value of each target device, and taking the minimum value in the difference as an adjustment reference value for indicating the comprehensive temperature deviation of the server.
In the embodiment of the application, the difference value between the ideal temperature value and the actual temperature value of each target device refers to the difference value obtained by subtracting the actual temperature value from the ideal temperature value of each target device, and if the difference value is a positive value, the actual temperature value of each target device is smaller than the ideal temperature value, so that the running requirement of a server is met, and the rotating speed of a system fan can be adjusted down according to the deviation. If the minimum value in the difference is a negative value, 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 system fan rotating speed needs to be up-regulated 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.
The minimum value in the difference value is used as an adjusting reference value for indicating the comprehensive temperature deviation of the server, the difference value is positive, and the rotating speed of the system fan is subjected to down-regulation treatment to improve the temperature of the target device. 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 the negative value of the difference 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 value of other target devices in the rotating speed of the server after the rotating speed is adjusted downwards can be ensured to be smaller than or equal to the ideal temperature value of the server.
And when the difference value is negative, the rotating speed of the system fan is subjected to up-regulation treatment 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 the negative value of the difference 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 smaller than or equal to the ideal temperature value of the target device.
In the embodiment of the present application, the server integrated temperature deviation may refer to a difference between the server integrated temperature and a server integrated temperature threshold, and the server integrated temperature may be specifically expressed by the following formula:
keyT＝Taim-Min((Ar·Tah-Ta)，(Br·Tbh-Tb)，(Cr·Tch-Tc)…)
Wherein keyT refers to the server integrated temperature; taim refers to the server integrated temperature threshold, having a target value that can be understood to be the server integrated temperature; ar, br and Cr respectively refer to weight values corresponding to the device A, the device B and the device C; tah, tbh, tch refers to the rated temperature of device a, device B, and device C, respectively; ta, tb, tc refer to the actual temperature values of device A, device B, and device C, respectively; min (a, b, c) is the minimum value of a, b, c.
The above formula can be used to obtain the comprehensive temperature deviation of the server 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 moment, and n is the nth moment; ta (n), tb (n), tc (n) refer to actual temperature values of the devices a, B, and 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 the ideal temperature value of each target device.
Step 103, controlling the operation of the fan based on the adjustment reference value.
In the embodiment of the application, the adjustment reference value is used for indicating the server integrated temperature deviation, and the fan operation is controlled based on the adjustment reference value, namely, the adjustment reference value is used for adjusting the integrated temperature deviation so that the server integrated temperature can be close to the server integrated temperature threshold, and when the adjusted integrated temperature deviation can enable the server integrated temperature to be close to the server integrated temperature threshold, a fan control signal is output to control the fan operation.
In one possible embodiment, controlling the operation of the fan based on the adjustment reference value includes:
When the adjustment 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 rotation speed of the fan to the target fan rotation speed based on the adjustment reference value;
based on the target fan speed, fan operation is controlled.
In the embodiment of the application, when the adjustment reference value is a negative value in the difference value between the ideal temperature value and the actual temperature value of each target device, it can be obtained that the actual temperature value of the target device is greater than the ideal temperature value of the target device in all the target devices. Since the adjustment reference value refers to the smallest difference value among the differences between the ideal temperature value and the actual temperature value of each target device, if the smallest difference value is a negative value, it is indicated that the target device corresponding to the smallest difference value is the target device with the largest difference between the actual temperature value and the ideal temperature value, so 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 appreciated 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 rotational speed of the fan to the target fan rotational speed based on the adjustment reference value includes:
taking negative value for adjusting reference value;
Based on the negative value of the adjusting reference value, obtaining a fan control signal through a PID control algorithm;
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 application, because the server integrated temperature deviation is the 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, the server integrated temperature deviation is obtained as a positive value, and the adjustment reference value for indicating the server integrated temperature deviation is a negative value, so that the adjustment reference value should be taken as a negative value first, the negative value of the adjustment reference value equal to the server integrated temperature deviation is obtained, and because the negative value of the adjustment reference value is equal to the server integrated temperature deviation, the adjustment of the negative value of the adjustment reference value can refer to the adjustment of the server integrated temperature deviation, the server integrated temperature deviation is input into the PID control algorithm, and the fan control signal is obtained until the server integrated temperature is less than or equal to the server integrated temperature threshold.
The PID control algorithm can adopt an incremental PID control algorithm, and a control formula of the incremental PID control algorithm can be expressed by the following equation:
where 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 proportional term coefficient in the PID control algorithm, Refers to integral term coefficients in a PID control algorithm,The derivative term coefficients in the PID control algorithm; e (n) is the n-th moment server integrated temperature deviation, e (n-1) is the n-1-th moment server integrated temperature deviation, and e (n-2) is the n-2-th moment server integrated temperature deviation.
The target fan speed of the fan is obtained according to the above equation, and the current speed of the fan is adjusted to the target fan speed according to the obtained fan control signal.
In one possible embodiment, controlling the fan to adjust from the current rotational speed to the target fan rotational speed in accordance with the fan control signal includes:
The current rotational speed of the fan is adjusted to a target fan rotational speed based on a PWM (Pulse Width Modulation, pulse width modulated) duty cycle signal.
In the embodiment of the application, the ideal temperature and the actual temperature of each target device are obtained, the smallest difference value in the differences of the target devices is taken as the 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.
Referring to fig. 2, a second flowchart of a server fan speed regulation method according to an embodiment of the present application is shown, and as shown in fig. 2, a server fan speed regulation method includes the following steps:
in step 201, an ideal temperature value and an actual temperature value of each target device in the server are obtained.
Step 202, calculating the difference between the ideal temperature value and the actual temperature value of each target device, and taking the minimum value in the difference as an adjustment reference value for indicating the comprehensive temperature deviation of the server.
In step 203, when the adjustment reference value is a negative value in the difference between the ideal temperature value and the actual temperature value of each target device, the current rotation speed of the fan is adjusted up to the target rotation speed of the fan based on the adjustment reference value, and the operation of the fan is controlled based on the target rotation speed of the fan.
Steps 201 to 203 of this embodiment are the same as steps 101 to 103 of the foregoing embodiment, and can be referred to each other, and the description of this embodiment is omitted here.
Step 204, when the adjustment reference value is a positive value in the difference between the ideal temperature value and the actual temperature value of each target device, the current rotation speed of the fan is adjusted up to the target rotation speed of the fan based on the adjustment reference value, and the operation of the fan is controlled based on the target rotation speed of the fan.
In the embodiment of the present application, since the adjustment reference value refers to the minimum value of the differences between the ideal temperature value and the actual temperature value of each target device, if the minimum value is a positive value, it is indicated that the actual temperature value of each target device is smaller than the ideal temperature value thereof.
It will be appreciated that when the actual temperature value of each target device is less than its own ideal temperature value, then the fan down-turn speed may be controlled in order to achieve lower power consumption and noise levels.
Illustratively, assume that actual temperature values and ideal temperature values of device a, device B, and device C in the server are shown in table 1, where the rated temperature of 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 degrees, and the corresponding weight value is 0.6; and the server integrated temperature threshold is set to 80, so that the following server integrated temperature and corresponding fan action can be obtained.
TABLE 1
Compared with the first embodiment, the embodiment shows the corresponding action of the fan when the actual temperature value of each target device is smaller than the ideal temperature value of the target device, the fan is controlled to downwards regulate the rotation speed, the resources operated by the server are reduced, so that the occupancy rate of the resources of the server is reduced, meanwhile, the embodiment of the application also enumerates the corresponding action of the fan when the actual temperature value is larger than the ideal temperature value of the target device of the server, and the weight value in the method can be set by a user according to the actual scene requirement, so that the advantages of good openness architecture and expandability of the method are exhibited.
