Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. 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 invention.
For the convenience of understanding of the embodiments of the present invention, the following description will be further explained with reference to specific embodiments, which are not to be construed as limiting the embodiments of the present invention.
Fig. 1 is a schematic flowchart of a method for controlling a cooling fan of a server according to an embodiment of the present invention, and as shown in fig. 1, the method specifically includes:
and S11, when the server is in the running state, acquiring the ambient temperature and air pressure information of the environment where the server is located.
The embodiment of the invention is applied to the heat dissipation condition of the server in different altitude areas, and the rotating speed of the same heat dissipation fan is low in atmospheric pressure in high altitude areas and is not beneficial to heat dissipation, so that the rotating speed needs to be increased to achieve the expected heat dissipation effect. In the research and development stage of the server, a temperature sensor and an air pressure sensor can be arranged at an air inlet of the server, and the ambient temperature and the air pressure of the environment where the server is located can be accurately monitored.
When the server is started and is in an operating state, heat dissipation is needed, the ambient temperature is monitored through the temperature sensor, the air pressure is monitored through the air pressure sensor, and the ambient temperature and the air pressure information monitored by the sensor are obtained.
And S12, determining a control strategy of a cooling fan of the server based on the ambient temperature and the air pressure information.
In the embodiment of the invention, a control strategy of the cooling fan can be preset, and the cooling fan can be controlled to increase the rotating speed or decrease the rotating speed according to the control strategy and control the corresponding rotating speed value.
Further, according to the obtained ambient temperature and atmospheric temperature, whether the rotating speed of the cooling fan of the current server is increased or decreased and a corresponding rotating speed value are judged.
For example, when the server operates in a low altitude (e.g., 2000 m) area, the ambient temperature is 20 degrees celsius, the air pressure is 70 kpa, and the rotation speed is 2000 rpm, the expected heat dissipation effect can be achieved; when the server operates in a high altitude (for example, 4000 meters) area, the ambient temperature is still 20 degrees celsius and the air pressure is 60 kpa, and since the air pressure becomes low and the heat dissipation effect is poor, the rotating speed may need to reach 3000 revolutions per second to achieve the same heat dissipation effect as that achieved at an altitude of 2000 meters.
And S13, controlling the cooling fan based on the control strategy so as to enable the component temperature of each component in the server to reach a preset condition.
Controlling the cooling fan based on the determined control strategy, and if the rotating speed of the cooling fan needs to be increased, controlling the cooling fan to increase the rotating speed; if it is determined that the rotational speed of the radiator fan needs to be reduced. The cooling fan is controlled to reduce the rotation speed so that the temperature of each component in the server reaches a preset condition, which may be a temperature (e.g., 30 degrees celsius) at which the server can be maintained to be operated smoothly.
According to the method for controlling the cooling fan of the server, provided by the embodiment of the invention, when the server is in an operating state, the ambient temperature and air pressure information of the environment where the server is located are obtained; determining a control strategy of a cooling fan of the server based on the environment temperature and the air pressure information; controlling the cooling fan based on the control strategy to make the component temperature of each component in the server reach a preset condition, compared with the prior art, the server management system calculates the current external temperature condition and gas condition according to the read atmospheric pressure value, different fan speeds are adjusted according to the calculated result, but an accurate ambient temperature T cannot be obtained according to the pressure P, so that the rotating speed of the fan required by the heat dissipation of the server under the current environment can not be obtained, and the design is not carried out according to the air pressure, when the method is applied to high altitude areas, the air pressure is low, the heat dissipation effect is poor, and the system heat dissipation effect is poor, by the method, the ambient temperature and air pressure information of the environment where the server is located can be accurately obtained, and the cooling fan is controlled according to the ambient temperature and the air pressure information, so that the cooling effect is ensured and the energy is saved.
Fig. 2 is a schematic flow chart of another method for controlling a cooling fan of a server according to an embodiment of the present invention, and as shown in fig. 2, the method specifically includes:
and S21, determining the corresponding relation between the rotating speed of the cooling fan and the ambient temperature and air pressure information based on the ambient temperature and air pressure information.
In the embodiment of the invention, the relationship between the ambient temperature and the air pressure information and the rotating speed of the cooling fan is determined in advance according to the heat dissipation design of the server, and then the optimized corresponding relationship diagram between the ambient temperature and the air pressure information and the rotating speed of the cooling fan is obtained according to the correction in the test stage, as shown in fig. 3.
It should be noted that the relationship diagram and the curve trend of fig. 3 are only examples, P is pressure, and P1> P2> P3.
The same rotating speed of the cooling fan is low in atmospheric pressure in the high-altitude area, which is not beneficial to cooling, so that the rotating speed needs to be increased to achieve the same expected cooling effect as that in the low-altitude area; the control strategy of the cooling fan can be classified into the following four strategies:
1. when the air pressure information is fixed and the environmental temperature is increased, the control strategy of the cooling fan is to increase the rotating speed;
2. when the air pressure information is fixed and the environmental temperature is reduced, the control strategy of the cooling fan is to reduce the rotating speed;
3. when the ambient temperature is fixed and the air pressure information is increased, the control strategy of the cooling fan is to reduce the rotating speed;
4. when the ambient temperature is fixed and the air pressure information is reduced, the control strategy of the cooling fan is to increase the rotating speed.
And S22, if the control strategy of the cooling fan is determined to be the increased rotating speed, acquiring the current running windshield of the cooling fan.
And S23, adjusting the running windshield to be increased so as to reduce the temperature of each component in the server.
The following description is made collectively for S22-S23:
if the current environment temperature is increased or the air pressure is reduced, the control strategy of the cooling fan can be determined to be the rotating speed increase, the current running windshield (for example, 1 gear) of the cooling fan is obtained, at the moment, the running windshield is adjusted to be increased, the cooling effect is improved, and the temperature of each component in the server is reduced.
Or, if the current ambient temperature is decreased or the air pressure is increased, it may be determined that the control strategy of the cooling fan is to decrease the rotation speed, and then the current running damper (for example, 2-gear) of the cooling fan is obtained, at this time, the running damper is adjusted to decrease, so as to save energy, as long as the component temperature of each component in the server is maintained in a stable running state.
Optionally, if the cooling fan does not have an operating windshield, the rotating speed value may be determined based on the corresponding relationship between the rotating speed of the cooling fan and the ambient temperature and air pressure information shown in fig. 3, the rotating speed of the cooling fan may be adjusted to the determined rotating speed value, and the rotating speed of the cooling fan may be dynamically adjusted along with the temperature change or the air pressure change.
And S24, acquiring the component temperature of each component in the server in real time.
In the embodiment of the invention, the component temperature of each component in the server can be acquired in real time in the running state of the server, and the acquisition mode can be that the temperature sensors are arranged on each component and the component temperature of each component is acquired through a plurality of temperature sensors.
And S25, when the duration of the temperature of the component is greater than or equal to the temperature threshold value and is greater than the time threshold value, performing temperature abnormity warning.
In the embodiment of the invention, the highest temperature threshold value which can be born by each component can be preset, when one or more component temperatures in the collected component temperatures of each component exceed the corresponding temperature threshold value and the duration time is longer than a time threshold value (for example, 30 seconds), the condition that the cooling fan does not work or the air channel is blocked can be preliminarily judged, and at the moment, a temperature abnormity alarm is started to prompt temperature abnormity in time, so that a user is informed to stop using and take cooling measures in time.
According to the method for controlling the cooling fan of the server, provided by the embodiment of the invention, when the server is in an operating state, the ambient temperature and air pressure information of the environment where the server is located are obtained; determining a control strategy of a cooling fan of the server based on the environment temperature and the air pressure information; controlling the cooling fan based on the control strategy to make the component temperature of each component in the server reach a preset condition, compared with the prior art, the server management system calculates the current external temperature condition and gas condition according to the read atmospheric pressure value, different fan speeds are adjusted according to the calculated result, but an accurate ambient temperature T cannot be obtained according to the pressure P, so that the rotating speed of the fan required by the heat dissipation of the server under the current environment can not be obtained, and the design is not carried out according to the air pressure, when the method is applied to high altitude areas, the air pressure is low, the heat dissipation effect is poor, and the system heat dissipation effect is poor, by the method, the ambient temperature and air pressure information of the environment where the server is located can be accurately obtained, and the cooling fan is controlled according to the ambient temperature and the air pressure information, so that the cooling effect is ensured and the energy is saved.
