Detailed Description
In order to avoid damage to the server due to an excessively high temperature of the server in the machine room, when the server in the machine room is cooled, the temperature of the server in the machine room during operation is usually reduced in a manner that heat dissipation of a fan is mainly performed and heat dissipation of an air conditioner is assisted, and therefore the server is cooled by the fan with high power consumption.
The inventor has found that, in the prior art, the fans are usually controlled to simultaneously increase and decrease at the same speed mechanically, that is, when the fan speed needs to be increased, the fan speeds are simultaneously increased, and when the fan speed needs to be decreased, the fan speeds are simultaneously decreased. However, in practical applications, the fans may be disposed at different positions, and the heat dissipation effects of the fans at the different positions on different servers are different, so that different fans may achieve the expected heat dissipation effects based on different rotation speeds for different servers. For example, for two fans, namely fan a and fan B, if the distance between fan a and target server a is smaller than the distance between fan B and target server B, when the target server a and target server B with the same temperature need to achieve the desired heat dissipation effect, the rotation speed of fan a may need to reach 80 revolutions per second, and the rotation speed of fan B may need to reach 100 revolutions per second. Therefore, in the process of radiating heat for the server, the rotating speed of the fans is controlled by adopting a mechanical same-lifting and same-descending mode for all the fans, so that the power consumption of part of the fans is overlarge, and necessary power consumption waste is generated. For example, in order to ensure the cooling effect of the fan, the prior art would increase the rotation speeds of the fan a and the fan B to 100 revolutions per second at the same time, but for the fan a, the expected heat dissipation effect on the target server a can be achieved when the rotation speed of the fan a reaches 80 revolutions per second, and therefore, increasing the rotation speed of the fan a to 100 revolutions per second would cause power consumption waste, and the power consumption of the fan a would be too large.
Based on this, the embodiment of the application provides a method for controlling the rotating speed of a fan, which controls the power consumption of the fan by adjusting the rotating speed of the fan, thereby achieving the effect of reducing the power consumption of the fan. Specifically, a first temperature and a second temperature are obtained, and/or a first distance and a second distance are obtained, wherein the first temperature is the temperature at a first target position on a first server, the second temperature is the temperature at a second target position on a second server, the first distance is the air channel distance between the target fan and the first target position, and the second distance is the air channel distance between the target fan and the second target position; and, can also obtain the standard rotational speed of the fan of this goal; then, according to the obtained first temperature and/or first distance, a first rotating speed weight value of the target fan relative to the first server can be determined, and according to the obtained second temperature and/or second distance, a second rotating speed weight value of the target fan relative to the second server can be determined; finally, based on the standard rotation speed, the first rotation speed weight value and the second rotation speed weight value of the target fan, the target rotation speed of the target fan can be calculated, so that the target fan can be controlled to operate at the target rotation speed. It is thus clear that based on the wind channel distance between the temperature of different servers and/or target fan and different servers, different rotational speed weighted values when confirming the target fan and cooling down to different servers dispel the heat, and then can determine the rotational speed when this target fan finally operates according to the rotational speed weight and the standard rotational speed of a plurality of servers, and like this, can make different fans dispel the heat to the server based on the rotational speed realization of difference through controlling the rotational speed weighted value, thereby when guaranteeing server radiating effect, the consumption of control fan reaches the effect that reduces this fan consumption.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, various non-limiting embodiments accompanying the present application examples are described below with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present application and 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.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a method for controlling a fan rotation speed according to an embodiment of the present application, where the method specifically includes:
s101: the method comprises the steps of obtaining a first temperature and a second temperature, and/or obtaining a first distance and a second distance, wherein the first temperature is the temperature of a first target position on a first server, the second temperature is the temperature of a second target position on a second server, the first distance is the air channel distance between a target fan and the first target position, and the second distance is the air channel distance between the target fan and the second target position.
In this embodiment, the rotation speed of the fan is generally related to the temperature of a location (for convenience of description, hereinafter referred to as a target location) on the server where heat dissipation and cooling are required, and the air channel distance between the fan and the target location.
Generally, in order to ensure the heat dissipation effect on the server, if the temperature at the target position on the server is higher, the rotation speed of the fan is also higher correspondingly, so that the airflow generated by the fan blades rotating at high speed can take away more heat at the target position, thereby reducing the temperature at the target position. Therefore, the rotation speed of the fan and the temperature of the server can be positively correlated within a certain range.
At the same time, the speed of the fan is also related to the air path distance between the fan and the target location. The air duct distance refers to a distance traveled by an air flow generated by rotation of fan blades of the fan in a process of flowing from the fan to a target position. In practical applications, based on the design of the hardware structure on the server, the airflow generated by the rotation of the fan blades may flow to the target position along the air duct installed on the server, and therefore, the air duct distance between the fan and the target position may be greater than the distance between the fan and the server. In general, the larger the air duct distance between the fan and the target position is, the smaller the air volume received by the target position is, and correspondingly, the heat dissipation efficiency of the fan for the target position is also lower; conversely, the more effective the air duct distance between the fan and the target position is, the larger the air volume received by the target position is, and correspondingly, the heat dissipation efficiency of the fan for the target position is also relatively higher.
Based on this, in this embodiment, the temperature at the target position on the server and/or the air channel distance between the fan and the target position may be obtained to determine the rotation speed of the fan. Specifically, a first temperature at a first target position on the first server and a second temperature at a second target position on the second server may be obtained, so as to determine the rotation speed of the fan according to the temperatures at different positions on the servers; and/or respectively acquiring the air channel distance between the target fan and a first target position on the first server and the air channel distance between the target fan and a second target position on the second server so as to determine the rotating speed of the fan according to different air channel distances.
It will be appreciated that the operating conditions (e.g., load, etc., operating power) of the different servers may not be the same, such that the temperature at the target location on two different servers is not the same. For example, if the load of a first server is greater than the load of a second server, the temperature generated at a first target location on the first server may be higher than the temperature generated at a second target location on the second server. Of course, even if the first server and the second server belong to the same server, the temperatures at different locations on the server may not be the same. For example, for a CPU and a hard disk on the same server, the heat generated by the server at the two locations during operation may be different, so that the temperatures at the CPU and the hard disk are different. Therefore, when the target fan performs heat dissipation and temperature reduction on the target positions on the first server and the second server, the rotating speed of the target fan can be determined according to the acquired temperatures (i.e. the first temperature and the second temperature) of the two target positions, so that the heat dissipation effect of the target fan on the two target positions can meet the expected requirement. In a specific implementation, temperature sensors may be respectively disposed at the first target position and the second target position, and the temperature at the first target position and the temperature at the second target position may be obtained by using the temperature sensors.
Similarly, the air path distances between different target positions and the target fan may also be different, and therefore, when the target fan cools the temperatures at the first target position and the second target position, the rotation speed of the target fan may be determined according to the acquired air path distance between the target fan and the first target position (i.e., the first distance) and the acquired air path distance between the target fan and the second target position (i.e., the second distance).
It should be noted that, in this embodiment, the air passage distance between the target fan and the target position and the temperature at the target position may be obtained at the same time, and the rotation speed of the target fan may be determined based on the air passage distance and the temperature.
In some exemplary embodiments, the target location may be specifically a location where the CPU and/or the hard disk on the server are located, because in practical applications, the CPU and the hard disk on the server are generally prone to generate a high temperature, which may cause damage to hardware of the server.
S102: and determining a first rotating speed weight value of the target fan relative to the first server according to the first temperature and/or the first distance, and determining a first rotating speed weight value of the target fan relative to the second server according to the second temperature and/or the second distance.
In this embodiment, in the process of determining the fan rotation speed, a weight value may be set for the rotation speed of the target fan based on the air passage distance between the target fan and the target position and/or the temperature at the target position. For the air duct distance, the smaller the air duct distance is, the larger the weight value of the rotating speed of the target fan is, and conversely, the larger the air duct distance is, the smaller the weight value of the rotating speed of the target fan is. That is, if the first temperature is greater than the second temperature, the first rotation speed weight value may be greater than the second rotation speed weight value. For the temperature at the target position, the higher the temperature is, the larger the weight value of the rotation speed of the target fan is, whereas the lower the temperature is, the smaller the weight value of the rotation speed of the target fan is. That is, if the first distance is greater than the second distance, the first rotation speed weight value may be smaller than the second rotation speed weight value.
In an exemplary embodiment, if the rotation speed weight value is determined based on the air duct distance and the temperature at the target position, a corresponding relationship between the air duct distance, the temperature at the target position, and the rotation speed weight value may be established in advance. The technician can establish the corresponding relationship based on the working experience of the rotating speed of the fan and the generated heat dissipation effect in practical application. Therefore, after the first temperature, the second temperature, the first distance and the second distance are obtained, the corresponding relation established in advance is inquired, and a first rotating speed weight value corresponding to the first temperature and the first distance and a second rotating speed weight value corresponding to the second temperature and the second distance can be determined. The first rotating speed weight value is the rotating speed weight value of the target fan relative to the first server, namely the rotating speed weight value relative to the first target position; the second rotation speed weight value is a rotation speed weight value of the target fan relative to the second server, namely a rotation speed weight value relative to the second target position.
S103: and acquiring the standard rotating speed of the target fan.
It is understood that the step S102 determines a target fan speed weight value, and the final actual output speed of the target fan can be obtained based on the target fan speed weight value and a standard speed. Based on this, the standard rotation speed of the target fan may also be obtained in this embodiment, for example, the standard rotation speed may be 1000 revolutions per second, 200 revolutions per second, and the like.
In an exemplary embodiment, the standard rotation speed of the target fan may be determined according to the temperature at the target position. Specifically, the target rotation speed of the target fan may be determined according to the acquired first temperature and the acquired second temperature. In this way, the standard rotational speed of the target fan may be correlated with the temperature at the target location on the server, such that the standard rotational speed is adjusted based on a change in the temperature at the target location on the server. It can be understood that if the temperature of the target position on the server is low, even if the rotating speed of the target fan is relatively low, the expected heat dissipation effect on the server can be achieved, and at this time, the standard rotating speed of the target fan can be set to be low; if the temperature at the target location on the server is high, the target fan is required to have a relatively high rotational speed to generate a stronger airflow to dissipate heat from the server as quickly as possible, and at this time, a higher standard rotational speed of the target fan may be set.
It should be noted that the execution sequence of each step presented in this embodiment is only an exemplary illustration, and is not used to limit the execution sequence of each step in this embodiment. In fact, the execution sequence between step S103 and the aforementioned steps S101 and S102 may be determined based on the needs of the actual application. For example, the execution sequence of step S103 may be before step S101, after step S102, or step S103 may be executed during execution of steps S101 and S102.
S104: and calculating the target rotating speed of the target fan based on the standard rotating speed, the first rotating speed weight value and the second rotating speed weight value of the target fan so as to control the target fan to operate at the target rotating speed.
In an exemplary specific implementation manner, after the first rotation speed weight value and the second rotation speed weight value are obtained, magnitudes of the first rotation speed weight value and the second rotation speed weight value may be compared, if the first rotation speed weight value is greater than the second rotation speed weight value, a product of the first rotation speed weight value and the standard rotation speed may be calculated, and the product is used as a target rotation speed of the target fan, and if the first rotation speed weight value is less than or equal to the second rotation speed weight value, a product of the second rotation speed weight value and the standard rotation speed may be calculated, and the product is used as a target rotation speed of the target fan, so as to control the target fan to operate at the target rotation speed.
Of course, in other possible embodiments, a first product of the first rotation speed weight value and the standard rotation speed and a second product of the second rotation speed weight value and the standard rotation speed may be calculated, and the first product and the second product are compared, if the first product is greater than the second product, the first product may be used as the target rotation speed of the target fan, and if the first product is not greater than the second product, the second product may be used as the target rotation speed of the target fan, so as to control the target fan to operate at the target rotation speed.
It should be noted that, in this embodiment, the target fan or other devices may control the rotation speed of the target fan to be the target rotation speed, for example, after the controller or other control devices of the target fan determines the target rotation speed, the target fan may be controlled to operate at the target rotation speed. In other embodiments, the target fan speed may be controlled by a worker (e.g., a technician or a maintenance worker) based on the target fan speed. For example, after the target rotation speed of the target fan is calculated, the target rotation speed may be presented to the worker through the display device, so that the worker may control the rotation speed of the target fan based on the target rotation speed displayed by the display device.
In practical applications, if the target positions at which the target fan needs to be cooled are three or more (for example, the number of servers in the machine room is three or more), in the process of determining the final output rotation speed of the target fan, the target rotation speed of the target fan may also be determined based on the temperatures at the three or more target positions and/or the air duct distances between the target fan and the three or more target positions. Specifically, if the target fan needs to lower the temperature of the three target positions, the first temperature, the second temperature, and a third temperature at a third target position on the third server, and/or the first distance, the second distance, and an air passage distance between the target fan and the third target position (hereinafter referred to as a third distance) may be obtained, and while the first rotation speed weight value and the second rotation speed weight value are determined, a third rotation speed weight value of the target fan relative to the third server may also be determined according to the third temperature and/or the third distance. In this way, when the target rotation speed of the target fan is calculated, the calculation may be performed based on the standard rotation speed, the first rotation speed weight value, the second rotation speed weight value, and the third rotation speed weight value of the target fan. Specifically, the first rotating speed weight value, the second rotating speed weight value and the third rotating speed weight value can be compared firstly, the maximum rotating speed weight value is determined, and if the maximum rotating speed weight value is the first rotating speed weight value, the product between the first rotating speed weight value and the standard rotating speed can be used as the target rotating speed of the target fan. The third server may be the same as the first server or the second server, or may be a server different from both the first server and the second server.
Similarly, if the target fan needs to cool the temperatures of more than three target positions, the process of determining the target rotation speed of the target fan is similar to the above process, and can be understood with reference to the above embodiment, which is not described herein again.
Further, when the target fan operates at the target rotation speed, the first rotation speed weight value and the second rotation speed weight value may be adjusted according to an actual heat dissipation effect of the target fan on the server. Specifically, when the target fan operates at the target rotation speed, the first rotation speed weight value or the second rotation speed weight value may be adjusted according to the temperature at the first target position and the temperature at the second target position. It can be understood that when the target fan operates at the target rotation speed for a period of time, if the temperature of the server does not change, whether the temperature of the server reaches the expected temperature or not can be measured by the temperature sensor, or whether the temperature change of the server before and after temperature reduction reaches the expected temperature difference or not, if the temperature change exceeds the expected temperature reduction effect, the rotation speed weight value can be adjusted to reduce the rotation speed output by the target fan, so that the power consumption of the target fan can be further reduced. If the target rotating speed of the target fan is obtained by multiplying the first rotating speed weight value by the standard rotating speed, the first rotating speed weight value can be adjusted, and similarly, if the target rotating speed of the target fan is obtained by multiplying the second rotating speed weight value by the standard rotating speed, the second rotating speed weight value can be adjusted, and the like. In other possible embodiments, the standard rotational speed may also be adjusted.
In an example, the heat dissipation effect of the server may be embodied as a temperature change of the server, and specifically may be measured by a temperature difference of the temperature of the server before and after heat dissipation; alternatively, the temperature that can be reached by the server after heat dissipation may be used, for example, if the temperature of the server is 65 degrees celsius before the target fan cools the server, and the temperature of the server can be reduced to the expected 45 degrees celsius after the target fan cools the server, the heat dissipation effect of the target fan may be considered to be good.
It should be noted that, in this embodiment, a process of controlling the rotational speed of the fan is described in detail by taking only one fan (i.e., the target fan) as an example, but in practical applications, there are usually a plurality of fans for cooling the server in the computer room, and for each fan, the final output rotational speed thereof may also be implemented by referring to the implementation manner of determining the target rotational speed of the target fan in this embodiment. Therefore, the most suitable rotating speed of the fan can be determined for each fan in the machine room, so that the cooling effect on the server is guaranteed, and meanwhile the power consumption of each fan can be reduced.
In this embodiment, the power consumption of the fan is controlled by adjusting the rotation speed of the fan, so that the effect of reducing the power consumption of the fan can be achieved.
