With the rise of technologies such as OCP, the server is required to provide more functions in the stby state, so that the server also needs to be powered on to work in the stby state, and the complete machine heat dissipation of the server in the stby state is ensured.
In view of the above, the present disclosure provides a method and an apparatus for controlling a fan in a standby state, an electronic device, and a machine-readable storage medium to solve the above problems.
The specific technical scheme is as follows.
In one embodiment, the present disclosure provides a method for controlling a fan in a standby state, which is applied to a CPLD device of a server, where the server further includes a standby-state operating module, and the method includes: judging whether the current server is in a standby state or not; if so, acquiring the temperature parameter of the standby state working module; and when the temperature parameter of the standby state working module is greater than or equal to a first preset threshold value, starting a standby fan included in the server to run.
Specifically, as shown in fig. 1, the method comprises the following steps:
in step S11, it is determined whether the current server is in a standby state.
And step S12, acquiring the temperature parameter of the standby state working module.
And step S13, when the temperature parameter of the standby state working module is greater than or equal to a first preset threshold value, starting a standby fan included in the server to run.
And monitoring the components working in the standby state of the server, and when the temperature of the standby state working module reaches a threshold value, starting the CPLD without providing a BMC (baseboard management controller) instruction, directly starting the fan corresponding to the standby state working module, and radiating heat for the standby state working module, thereby solving the problem that the fan control cannot be realized in the standby state of the server.
In one embodiment, when the temperature parameter of the standby state operating module is greater than or equal to a first preset threshold, the enabling a standby fan included in a server to start running includes: and when the temperature parameter of the standby state working module is greater than or equal to a first preset threshold value, starting a standby fan included in the server to run and the rotating speed of the standby fan does not exceed a preset upper limit, wherein the preset upper limit is obtained according to the parameter of the standby fan and the standby power supply parameter of the power supply of the server.
In one embodiment, a temperature parameter of a standby state operating module is obtained; and when the temperature parameter of the standby state working module is less than or equal to a second preset threshold value, stopping the operation of a standby fan included in the server.
In one embodiment, the server includes a power monitoring module, the method further comprising: acquiring an interrupt signal sent by a power supply monitoring module; stopping the operation of a standby fan included in the server according to the interrupt signal; the interruption signal is sent by the power supply monitoring module when the server power supply is in standby power supply overload.
Generally, the power consumption of a high-performance fan can reach 50W, which is greater than the power that a PSU (server power supply) can provide in the stby state (standby state), so the technical scheme provided by the present disclosure needs to implement the stby state to perform fan control to ensure the stable operation of the system.
According to the position of a component needing to work in the stby state in the server, namely the physical installation position of the standby state working module, the corresponding fan is selected, the corresponding power supply is designed to be in the standby state and can supply power, and when the server is in the stby state, the standby power supply module of the PSU can supply power for the fan.
In the Main state (the on-line state of the server), the BMC transmits the rotating speed control signal to the CPLD, and the CPLD transmits the rotating speed control signal to the fan to realize the rotating speed control of the fan, so that in the Main working state, the BMC realizes the rotating speed control of the fan through the CPLD.
In the stby stage, the CPLD directly controls the fan, and the CPLD does not depend on the rotating speed information provided by the BMC to realize the rotating speed control of the fan, which is specifically as follows.
When the standby state working module is configured and installed in the server, the corresponding in-place signal is transmitted to the CPLD, and the CPLD enables the corresponding stby fan according to the in-place signal. Correspondingly, if the corresponding standby state working module is not in place, the corresponding fan cannot rotate;
the standby state working module is provided with a temperature sensing element, and the temperature sensing element sets a high-temperature working threshold value, namely a first preset threshold value, according to the working temperature requirement of the standby state working module. When the working temperature of the working module in the standby state exceeds a first preset threshold value, the temperature sensing element generates an electric signal and transmits the electric signal to a corresponding pin of the CPLD, so that the CPLD can sense the electric signal.
After receiving the signal that the temperature of the working module in the standby state exceeds the limit, the CPLD gradually increases the rotating speed from 0% to M%, wherein M% is the rotating speed value corresponding to the power consumption value of the power supply capable of stabilizing the power supply in the standby state of the server, which is calculated according to the type of the fan.
When the fan rotates, the working temperature of the corresponding standby state working module gradually decreases until the heat balance is reached, namely the working temperature decreases to a second preset threshold value, the electric signal of the temperature sensing element is de-triggered, the CPLD is sensed, and the fan stops rotating.
The PSU standby power supply module is provided with a power supply monitoring module, when the power supply of the PSU standby power supply module exceeds a safety range, such as 30W, the power supply monitoring module sends an interrupt signal to a corresponding pin of the CPLD, the CPLD can sense the interrupt signal, the rotation of the standby fan is stopped, and the stable operation of the system is ensured.
In one embodiment, the present disclosure also provides a standby state fan control apparatus, as shown in fig. 2, applied to a CPLD device of a server, where the server further includes a standby state operating module, and the apparatus includes: a judging unit 21, configured to judge whether a current server is in a standby state; the acquiring unit 22 is used for acquiring the temperature parameter of the standby state working module when the server is in the standby state; and the control unit 23 is configured to start a standby fan included in the server to operate when the temperature parameter of the standby state operating module is greater than or equal to a first preset threshold.
In one embodiment, when the temperature parameter of the standby state operating module is greater than or equal to a first preset threshold, the enabling a standby fan included in a server to start running includes: and when the temperature parameter of the standby state working module is greater than or equal to a first preset threshold value, starting a standby fan included in the server to run and the rotating speed of the standby fan does not exceed a preset upper limit, wherein the preset upper limit is obtained according to the parameter of the standby fan and the standby power supply parameter of the power supply of the server.
In one embodiment, a temperature parameter of a standby state operating module is obtained; and when the temperature parameter of the standby state working module is less than or equal to a second preset threshold value, stopping the operation of a standby fan included in the server.
In one embodiment, the server includes a power monitoring module, and the apparatus further includes: acquiring an interrupt signal sent by a power supply monitoring module; stopping the operation of a standby fan included in the server according to the interrupt signal; the interruption signal is sent by the power supply monitoring module when the server power supply is in standby power supply overload.
