Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
First, some technical terms related to the present application are explained:
the high-density storage server can integrate more storage devices (such as hard disks) in a smaller physical space, and the density of the storage devices is larger.
PID parameters comprise Proportional (proportionality), Integral (Integral) and Differential (Differential) parameters, and are used for calculating according to the input deviation value and the functional relation of the Proportional, Integral and Differential, and the calculation result is used for outputting control so as to realize simple and complex regulation functions.
At present, for heat dissipation control of a hard disk of a high-density storage server, the temperature of the hard disk can be monitored by temperature sensors distributed on a hard disk back plate of the high-density storage server, and PID control is performed based on the temperature of the hard disk to adjust the rotating speed of a fan, so that heat dissipation is performed on the hard disk. The inventor finds out in the research process that: the temperature sensor can receive hard disk temperature and ambient temperature's combined action, receives ambient temperature's influence, and the difference between temperature sensor and the hard disk actual temperature can change. For example, when ambient temperature is in the low temperature section, temperature sensor receives the influence of environment cold wind easily, and temperature sensor's temperature and hard disk actual temperature difference can increase, and the hard disk has the overtemperature hazard. In this case, the current solution is to reduce the effect of this temperature difference by increasing the fan speed when the ambient temperature is relatively low, but this approach causes the system power consumption to increase. In addition, heat dissipation control can be performed by acquiring the actual temperature of the hard disk, but the method is limited by the influence of the performance of the hard disk and cannot acquire the temperature of the hard disk frequently, so that the speed regulation of the fan is delayed.
Based on the above problems, the present application provides a heat dissipation control method, apparatus, device, and storage medium, which combine the current ambient temperature and the actual temperature of the hard disk to perform speed regulation control on the fan, so as to achieve the purpose of avoiding the high temperature risk of heat dissipation components such as the hard disk.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, in the application scenario, heat dissipation control needs to be performed on a plurality of hard disks 110 of the high-density storage server, a plurality of temperature sensors 120 are distributed on a back plate of the hard disk 110, the plurality of temperature sensors 120 may be respectively used for acquiring an ambient temperature and a temperature of the hard disk 110, and the operation of the fan 130 is controlled according to the ambient temperature acquired by the plurality of temperature sensors 120 and the temperature of the hard disk 110, so as to dissipate heat from the hard disk 110. The wind flow direction of the inlet wind in fig. 1 can be seen in particular in fig. 2. In the scenario illustrated in fig. 2, the wind flow direction is into the page perpendicular to the plane of the paper. The specific implementation process of controlling the operation of the fan 130 according to the ambient temperature and the hard disk temperature obtained by the temperature sensor 120 can be referred to the schemes of the following embodiments.
It should be noted that fig. 1 is only a schematic diagram of an application scenario provided in this embodiment, and this embodiment of the present application does not limit the devices included in fig. 1, and also does not limit the positional relationship between the devices in fig. 1.
Fig. 3 is a flowchart of a heat dissipation control method according to an embodiment of the present application. The method of the embodiment of the application can be applied to electronic equipment, and the electronic equipment can be a server or a server cluster and the like. As shown in fig. 3, the method of the embodiment of the present application includes:
s301, acquiring the current ambient temperature.
In the embodiment of the present application, exemplarily, the heat dissipation of the hard disk of the high-density storage server needs to be controlled, and the temperature sensor is arranged on the hard disk back plate of the high-density storage server close to the air inlet, so that the current ambient temperature can be obtained through the temperature sensor.
In practical application, if a plurality of (for example, two or more) temperature sensors are arranged on the hard disk backboard of the high-density storage server close to the air inlet, the larger value of the environmental temperatures respectively obtained by the plurality of temperature sensors is determined as the current environmental temperature; or, the average value of the environmental temperatures respectively obtained by the plurality of temperature sensors is determined as the current environmental temperature, and the present application does not limit the specific implementation manner of obtaining the current environmental temperature according to the environmental temperatures respectively obtained by the plurality of temperature sensors, and this is only an example.
S302, determining a temperature interval to which the current environment temperature belongs.
After the current ambient temperature is obtained, the temperature interval to which the current ambient temperature belongs may be determined. The temperature range can be understood as a numerical range including a plurality of temperatures, and can be specifically set according to actual conditions. Alternatively, the temperature interval may be predetermined based on a number of experimental test data.
Illustratively, the temperature range can be divided into three ranges, such as 0 ℃ to 10 ℃ for the A range, 10 ℃ to 20 ℃ for the B range, and 20 ℃ to 35 ℃ for the C range. In this example, if the current ambient temperature is 8 ℃, it may be determined that the temperature interval to which the current ambient temperature belongs is the interval a.
And S303, determining the target rotating speed of the fan according to the PID parameters corresponding to the temperature interval and the first temperature of the target heat dissipation part.
Wherein, different temperature intervals can correspond to different PID parameters. Still taking the above example as an example, the PID parameter corresponding to the interval a may be specifically a proportion of 0.2, an integral of 0.1, and a differential of 0.01; the PID parameter corresponding to the interval B can be specifically a proportion of 0.3, an integral of 0.2 and a differential of 0.01; the PID parameter corresponding to the C interval may specifically be a proportion of 0.4, an integral of 0.3, and a differential of 0.01.
The target heat dissipation component includes, but is not limited to, components such as a hard disk that release heat during operation. The first temperature of the target heat sink member may be obtained by a temperature sensor corresponding to the target heat sink member, for example. As a possible embodiment, the temperature sensor for obtaining the first temperature and the temperature sensor for obtaining the current ambient temperature may be different temperature sensors. The term "different" here can be understood as that the distribution positions of the temperature sensors are different, for example, the temperature sensors are distributed at different positions of the hard disk backplane; alternatively, it can be understood that the temperature range corresponding to the temperature sensor is different, and the like.
After the temperature interval to which the current environment temperature belongs is determined, the PID parameter corresponding to the current environment temperature can be determined according to the temperature interval; the target speed of the fan may then be determined based on the determined PID parameter and the first temperature. As to how to determine the target rotation speed of the fan, reference may be made to related art or subsequent embodiments, which are not described herein again.
And S304, controlling the operation of the fan based on the target rotating speed.
In the embodiment of the application, after the target rotating speed of the fan is determined, the operation of the fan can be controlled based on the target rotating speed, so that heat is dissipated for the target heat dissipation part, and the temperature of the target heat dissipation part is prevented from being too high.
According to the heat dissipation control method provided by the embodiment of the application, the temperature interval to which the current environment temperature belongs is determined by obtaining the current environment temperature, the target rotating speed of the fan is determined according to the PID parameter corresponding to the temperature interval and the first temperature of the target heat dissipation part, and the operation of the fan is controlled based on the target rotating speed. Because the first temperature (namely the actual temperature) of the target heat dissipation part is considered when the target rotating speed of the fan is determined, the current environment temperature is combined, namely the target rotating speed of the fan is determined according to the PID parameter corresponding to the temperature interval to which the current environment temperature belongs and the first temperature, the problem that the difference between the temperature for determining the target rotating speed of the fan and the actual temperature of the hard disk is changed due to the influence of the environment temperature can be avoided, heat dissipation is effectively performed on the target heat dissipation part (for example, the hard disk), the risk of over-temperature of the target heat dissipation part is avoided, and the service lives of the target heat dissipation part and the electronic equipment comprising the target heat dissipation part can be prolonged.
Fig. 4 is a flowchart of a heat dissipation control method according to another embodiment of the present application. On the basis of the above embodiment, the present embodiment further describes how to determine the target rotation speed of the fan in step S303. As shown in fig. 4, step S303 may further include:
s401, determining a distribution subinterval of the first temperature in the temperature interval.
Wherein, the distribution subinterval comprises a stable interval and a non-stable interval.
In the embodiment of the application, the different temperature intervals have corresponding temperature distribution subintervals, and the distribution subintervals include a stable interval and an unstable interval. After the first temperature is obtained, a distribution subinterval of the first temperature in the temperature interval may be determined. For example, the distribution subinterval in the temperature interval may be predetermined from a large amount of experimental test data. Illustratively, the temperature interval can be divided into A, B, C three intervals, wherein, the stable interval in the interval A is a ℃ to b ℃, and the unstable interval is less than a ℃ and more than b ℃; the stable interval in the interval B is c-d ℃, and the unstable interval is < c ℃ and > d ℃; the stable interval in the interval C is e-f ℃, and the unstable intervals are < e ℃ and > f ℃. Illustratively, the stable interval in the interval a is 45 ℃ to 48 ℃, and if the first temperature of the hard disk is 46 ℃, the distribution subinterval of the first temperature of the hard disk in the interval a can be determined as the stable interval; if the first temperature of the hard disk is 50 ℃, the distribution subinterval of the first temperature of the hard disk in the interval a can be determined to be an unstable interval.
S402, determining the target rotating speed of the fan according to the PID parameters corresponding to the distribution subintervals.
In this step, different distribution subintervals correspond to different PID parameters. After the distribution subinterval of the first temperature in the temperature interval is determined, the target rotating speed of the fan can be determined according to the PID parameters corresponding to the distribution subinterval. Illustratively, the PID parameters corresponding to the distribution subintervals may be predetermined from a large amount of experimental test data. For example, if the distribution subinterval is a stable interval, the PID parameter is relatively small, and the PID parameter is, for example, 0.2, 0.1, 0.01, so as to control the rotation speed of the fan to be relatively smoothly adjusted; if the distribution subinterval is an unstable interval, for example, the temperature of the hard disk is to be rapidly cooled down, the PID parameter is relatively large, and the PID parameters are, for example, 0.4, 0.2, and 0.01, so as to control the rotation speed of the fan to be rapidly adjusted, thereby rapidly dissipating heat of the hard disk.
Further, determining the target rotation speed of the fan according to the PID parameters corresponding to the distribution subintervals may include: determining the rotating speed change quantity of the fan according to the PID parameters corresponding to the distribution subintervals, the first temperature and the temperatures at a plurality of moments close to the current moment; and determining the target rotating speed of the fan according to the rotating speed change quantity and the actual rotating speed of the fan at the moment before the current moment.
Illustratively, the amount of change in the rotational speed of the fan is determined by the following formula one:
ΔPWM(n)＝Kp×[T(n)-T(n-1)]+Ki×[T(n)-SP]+Kd×[T(n)+T(n-2)-2×T(n-1)]
wherein, Δ PWM (n) represents the variation of the rotation speed of the fan at n time, n represents n time, KpRepresenting the P coefficient, K, in a PID parameteriRepresenting the I coefficient, K, in a PID parameterdThe D coefficient in the PID parameter is shown, T (n) shows the temperature at the time n, T (n-1) shows the temperature at the time n-1, T (n-2) shows the temperature at the time n-2, and SP shows the control point and corresponds to the value of the stable interval.
Exemplarily, assuming that the current ambient temperature is 8 ℃, the temperature interval to which the current ambient temperature belongs is determined to be an interval a (0 ℃ to 10 ℃), the stable interval in the interval a is 45 ℃ to 48 ℃, and assuming that the first temperature t (n) of the target heat dissipation component at the current time is 45 ℃, the stable interval of the first temperature of the target heat dissipation component in the interval a can be determined, accordingly, the control point SP is 48 ℃, the control point K is 45 ℃, "K" is apIs 0.2, KiIs 0.1, Kd0.01, assuming that T (n-1) is 44 ℃ and T (n-2) is 44 ℃, the change Δ pwm (n) in the rotation speed of the fan at the current time can be obtained by the above equation one:
ΔPWM(n)＝0.2×[45-44]+0.1×[45-48]+0.01×[45+44-2×44]＝-0.09
it can be determined that the rotation speed of the fan is about to decrease by 0.09% from the rotation speed change amount Δ pwm (n) of the fan being-0.09, and it can be determined that the target rotation speed of the fan is 59.91% assuming that the actual rotation speed of the fan at the previous timing to the present timing is 60%. It should be noted that, since the rotation speeds of different fans are different, the target rotation speed of the fan determined herein is the rotation speed percentage to be adjusted by the fan.
In some embodiments, before step S303, the heat dissipation control method may further include acquiring a first temperature of the target heat dissipation component. In one possible implementation, the first temperature may be obtained by: acquiring the temperature monitored by at least one temperature sensor, wherein the at least one temperature sensor is used for monitoring the temperature of a target heat dissipation component; determining a maximum of the temperatures monitored by the at least one temperature sensor as a first temperature of the target heat sink member.
Illustratively, there are a plurality of target heat dissipation components, such as hard disks of high-density storage servers, and each high-density storage server has a temperature sensor on its hard disk backplane for monitoring the temperature of each hard disk. Thus, the temperature monitored by the at least one temperature sensor can be obtained. After obtaining the temperatures monitored by the at least one temperature sensor, a maximum value of the temperatures monitored by the at least one temperature sensor can be determined, which is the first temperature of the target heat sink component. Illustratively, if the temperatures respectively monitored by the 3 temperature sensors are 6 ℃, 7 ℃ and 8 ℃, respectively, then 8 ℃ can be determined as the first temperature of the target heat sink member.
According to the heat dissipation control method provided by the embodiment of the application, the target rotating speed of the fan is determined according to the PID parameters corresponding to the distribution subinterval of the first temperature of the target heat dissipation part in the temperature interval, so that the problem that the difference between the temperature for determining the target rotating speed of the fan and the actual temperature of the hard disk is changed due to the influence of the environmental temperature can be avoided, heat is effectively dissipated for the target heat dissipation part (such as the hard disk), the risk of over-temperature of the target heat dissipation part is avoided, and the service lives of the target heat dissipation part and the electronic equipment comprising the target heat dissipation part can be prolonged.
Fig. 5 is a flowchart of a heat dissipation control method according to another embodiment of the present application. As shown in fig. 5, on the basis of the foregoing embodiment, the method of the embodiment of the present application may include:
s501, obtaining the current environment temperature.
And S502, determining the temperature interval to which the current environment temperature belongs.
In the embodiment of the present application, specific implementation processes of S501 and S502 may refer to the related description of the embodiment shown in fig. 3, and are not described herein again.
S503, determining a distribution subinterval of the first temperature in the temperature interval.
Wherein, the distribution subinterval comprises a stable interval and a non-stable interval.
For a detailed description of this step, reference may be made to the description related to S401 in the embodiment shown in fig. 4, and details are not repeated here.
S504, determining a first rotating speed of the fan according to the PID parameters corresponding to the distribution subintervals.
For example, after the PID parameters corresponding to the distribution subinterval of the first temperature in the temperature interval are obtained, the first rotation speed of the fan may be determined according to the above formula one.
And S505, acquiring a second temperature of the target heat dissipation component.
For example, the target heat dissipation component is a hard disk of the high-density storage server, and the actual temperature of the hard disk, which is the second temperature of the hard disk, may be obtained through a hard disk temperature monitoring chip of the high-density storage server.
Further, obtaining the second temperature of the target heat sink member may include: sequentially acquiring the temperature of each target heat dissipation component within a preset time range; determining a maximum value among the temperatures of the target heat sink members as a second temperature of the target heat sink members.
For example, the preset time period ranges from 10 minutes, and N target heat dissipation members exist, and the temperature of each of the N target heat dissipation members is sequentially obtained within the 10 minute range. Assuming that the obtained temperature of the first target heat dissipation component is 20 ℃, the temperature of the second target heat dissipation component is 30 ℃, and the temperature of the third target heat dissipation component is 35 ℃, sequentially obtaining the temperature of each target heat dissipation component until the obtained temperature of the nth target heat dissipation component is 40 ℃, and if the temperature of the nth target heat dissipation component is the maximum value of the temperatures of the N target heat dissipation components, determining that the second temperature of the target heat dissipation component is 40 ℃.
And S506, determining a second rotating speed of the fan according to the PID parameter corresponding to the second temperature.
