In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application are described in detail below with reference to the accompanying drawings and specific embodiments:
referring to fig. 1, a schematic structural diagram of an apparatus according to an embodiment of the present disclosure is shown. The equipment comprises a power supply module, a printed circuit board (PCB for short) and a fan. Of course, the device may also include other modules, which are not limited in this application.
The power module is used for providing power required by operation for the equipment; the PCB board includes various components for implementing functions required by the device, for example, the PCB board of the switching device mainly includes a controller chip for implementing ethernet access, which is referred to as an MAC chip for short; the fan is used for dispelling the heat to equipment to each device normal work in the assurance equipment.
Here, it should be noted that when the power consumption of the device is large, the device may be cooled by using a parallel connection of multiple fans, for example, 4 fans are disposed in the device shown in fig. 1. Of course, the number of fans deployed in the equipment is not limited in the present application, and specifically, the required number of fans may be deployed according to actual heat dissipation requirements.
Referring to fig. 2, a flow chart of a fan control method according to an embodiment of the present disclosure is shown. The process may include the steps of:
step 201, when it is detected that the temperature of the area to be cooled in the device exceeds a preset temperature threshold, the temperature of the air inlet of each fan is obtained.
In the embodiment of the application, each fan is provided with a corresponding temperature measurement module, and the temperature measurement module is used for detecting the temperature of an air port of the fan.
In order to not increase the equipment cost obviously, the temperature measuring module can adopt a temperature sensing circuit module formed by discrete elements such as a temperature sensing resistor, temperature sensing ceramic and the like.
As an example, in the embodiment of the present application, an induced draft fan may be used as the fan. The heat dissipation effect of the exhausting fan is generally better than that of the blowing fan.
When the temperature measuring module is installed on the exhaust fan, the temperature measuring module can be installed at the air inlet of the exhaust fan.
The equipment operation can inevitably produce the heat, if high temperature in the equipment, can influence the stability of device operation in the equipment, for this reason, need monitor the temperature in the equipment to in time control fan dispels the heat to equipment.
In the embodiment of the application, when the temperature of the area to be cooled in the device is monitored to exceed the preset temperature threshold, the area to be cooled is determined to be cooled, and at the moment, the air port temperature measured by the temperature measuring module corresponding to each fan can be obtained.
Here, it should be noted that the region to be dissipated generally refers to a high-temperature region of the device where power consumption is large, for example, a MAC chip in a switching device. The temperature of the MAC chip is typically read from within the MAC chip without the need for additional temperature sensors.
Step 202, judging whether a first fan and a second fan with air port temperature difference values larger than a preset first temperature difference value exist in the plurality of fans, wherein the air port temperature of the first fan is higher than that of the second fan.
Here, the first fan, the second fan, and the first temperature difference are only named for convenience of distinction and are not intended to be limiting.
It should be noted that the temperature of the air outlet of the fan is influenced to some extent by the position of the fan, which may reflect the current ambient temperature of the fan. For example, in fig. 1, the fan 1 is closer to the upper thermal zone of the PCB, and the fan 4 is farther from the upper thermal zone of the PCB, so the temperature of the air outlet (ambient temperature) of the fan 1 is usually higher than the temperature of the air outlet (ambient temperature) of the fan 4. That is, the temperature of the environment in which each fan is located may be different in the same device.
When the first fan and the second fan with the air port temperature difference value larger than the preset first temperature difference value exist in the plurality of fans, the fact that the environment temperature where the first fan is located is far higher than the environment temperature where the second fan is located is indicated. The higher the temperature of the environment in which the fan is located, the faster the fan will be damaged and the shorter the life. In order to avoid the influence of too short service life of a single fan on the stability of the equipment, the fan adjustment can be performed by only controlling the second fan with lower ambient temperature to increase the rotating speed for heat dissipation, that is, the step 203 is performed.
If it is determined through this step that there is no first fan and no second fan in the plurality of fans, where the temperature difference between the air outlets of the two fans is greater than the preset first temperature difference, that the ambient temperatures of the fans are substantially equivalent, and the lifetimes of the fans are substantially the same under the influence of the ambient temperatures, then step 204 is performed.
Step 203, the second fan is controlled to increase the rotation speed to reduce the temperature of the area to be cooled.
By increasing the rotation speed of the second fan with a low temperature, a large amount of heat can be discharged from the second fan, so that the temperature in the equipment (especially the temperature of the area to be radiated) is reduced, and meanwhile, the temperature of the environment where the first fan is located can be reduced.
It can be seen that the service life of the first fan is prolonged by sacrificing the service life of the second fan to a certain extent (the higher the rotating speed is, the shorter the service life is), so that the service lives of the fans in the equipment are balanced, and the overall stability of the equipment is improved.
And step 204, uniformly controlling the rotation speed of each fan to be increased so as to reduce the temperature of the area to be cooled.
Under the condition that the environmental temperatures of the fans are basically the same, the rotating speeds of the fans are controlled to be basically equivalent (balanced), so that the service lives of the fans are basically consistent, and the overall stability of the equipment is improved.
At this point, the flow shown in fig. 2 is completed.
It can be seen from the flow shown in fig. 2 that in the embodiment of the present application, the ambient temperature of each fan can be accurately determined by monitoring the temperature of the air inlet of each fan. When the environmental temperature difference of each fan is great, the rotating speed of the fan with low environmental temperature is increased to balance the service life of each fan, so that the running stability of the equipment is improved.
As an embodiment, when it is determined that there are the first fan and the second fan having the air outlet temperature difference larger than the preset first temperature difference in the plurality of fans through step 202, it may be further determined whether a difference between a rotation speed of the second fan and a rotation speed of the first fan is smaller than the preset first rotation speed difference.
It is understood that the first rotation speed difference is referred to only for convenience of distinguishing and is not intended to be limiting.
When the difference between the rotation speed of the second fan and the rotation speed of the first fan is smaller than the preset first rotation speed difference, it is indicated that the rotation speed of the second fan is less than or equal to the rotation speed of the first fan, or the rotation speed of the second fan is higher than the rotation speed of the first fan but the deviation is not large, at this time, step 203 may be turned to control the second fan to increase the rotation speed for heat dissipation.
When the difference between the rotation speed of the second fan and the rotation speed of the first fan is not less than the preset first rotation speed difference, it is indicated that the rotation speed of the second fan is already obviously higher than the rotation speed of the first fan. If the rotation speed of the second fan is continuously increased, the damage of the second fan is accelerated, so that the service life of the second fan is obviously shortened, therefore, in the embodiment of the present application, step 204 is executed, and the rotation speed of each fan is increased through balanced control to perform heat dissipation.
It can be seen that, in the embodiment of the present application, in addition to considering the influence of the ambient temperature on the life of the fan, the influence of the fan speed on the life of the fan is also considered, and the speed of the fan at a low temperature cannot be adjusted up without limitation.
Referring to fig. 3, a fan status warning process is shown in the embodiment of the present application. The process may include the steps of:
step 301, periodically recording the corresponding relationship among the temperature of the area to be cooled, the temperature of the air inlet of each fan and the rotating speed.
During the operation of the apparatus, the temperature of the area to be heat-dissipated in the apparatus and the corresponding relationship between the temperature of the air inlet and the rotation speed of each fan may be periodically (for example, every 30 minutes) recorded, as shown in table 1.
Figure BDA0002973736330000081
TABLE 1
Of course, other information, such as the number of UP ports of the switching device, may also be recorded in the table, which is not limited in this application.
In addition, it should be noted that, in the operation process of the equipment, the air outlet temperature and the rotation speed of each fan corresponding to the same temperature of the area to be cooled in the recorded corresponding relationship may be averaged continuously, so as to dynamically maintain the corresponding relationship between the temperature of the area to be cooled and the air outlet temperature and the rotation speed of each fan.
E.g. T mac_1 And T mac_3 If the same, T can be obtained f1_1 And T f1_3 As fan 1 at T mac_1 (T mac_3 ) The lower tuyere temperature; will S f1_1 And S f1_3 As the mean value of fan 1 at T mac_1 (T mac_3 ) A lower rotation speed; similarly, it can be determined that other fans are at T respectively mac_1 (T mac_3 ) Lower tuyere temperature and rotational speed.
Through the processing, the number of the maintained corresponding relations can be reduced, the occupation of equipment resources is reduced, and the accuracy of the maintained corresponding relations can be improved.
Through the steps, the historical records of the corresponding relationship between the temperature of the area to be radiated and the temperature and the rotating speed of the air inlet of each fan can be obtained.
Step 302, obtaining the temperature of the current area to be cooled, the temperature of the air inlet of each fan and the rotating speed.
Step 303, searching a target corresponding relation of the temperature hit of the current to-be-cooled area from the recorded corresponding relation.
Namely, according to the temperature of the currently acquired region to be cooled, the corresponding relation of the temperature of the region to be cooled is searched and recorded. In the embodiment of the present application, the found corresponding relationship including the temperature of the area to be cooled is referred to as a target corresponding relationship.
It is to be understood that the target correspondence relationship is named merely for convenience of distinction and is not intended to be limiting.
Here, it should be added that, when the difference between the acquired temperature of the area to be cooled and the temperature of the area to be cooled recorded in the corresponding relationship falls within a preset temperature difference range, it may be determined that the corresponding relationship includes the currently acquired temperature of the area to be cooled.
Step 304, for each fan, if the difference between the air outlet temperature of the fan recorded in the target corresponding relationship and the air outlet temperature of the fan currently obtained exceeds a preset second temperature difference, or the difference between the rotating speed of the fan in the target corresponding relationship and the rotating speed of the fan currently obtained exceeds a preset second rotating speed difference, reporting the early warning information of the fan.
Here, the second temperature difference and the second speed difference are only given names for convenience of distinction and are not intended to be limiting.
In the step, the air port temperature and the rotating speed of each fan at the temperature of the current area to be cooled are compared with the air port temperature and the rotating speed of each fan at the temperature of the area to be cooled in the historical record, and if parameters (such as the air port temperature and the rotating speed) with large deviation occur, the corresponding fan is indicated to be possible to break down.
For example, the deviation between the current rotation speed of the fan 1 and the rotation speed of the fan 1 at the same temperature of the area to be cooled in the history is not large, but the temperature of the air outlet of the current fan 1 is significantly higher than the temperature of the air outlet of the fan 1 at the same temperature of the area to be cooled in the history, and it is considered that the cooling efficiency of the fan 1 may be abnormal.
Aiming at the abnormal fan, the early warning information of the fan is reported in the embodiment of the application, so that maintenance personnel can be reminded to process the fan in time, and the stable operation of equipment can be ensured.
The flow shown in fig. 3 is completed.
The fault monitoring and early warning of the fan can be realized through the process shown in fig. 3, so that the stability of the equipment is further ensured.
