Problems solved by technology

However, the current control of the fan makes the fan start to work at the beginning of the server startup. In fact, at this time, the processor and other components of the server do not heat up significantly, which will cause a waste of power.
Especially for a large computer room, even when the fan speed is very low, the fans of thousands of servers consume a lot of power.

Embodiment 1

[0041] like figure 1 As shown, this embodiment provides a server fan control method, including the following steps.

[0042] S101, reading a preset temperature threshold.

[0043] According to the temperature control requirements, the temperature threshold is preset. When the CPU temperature is higher than the threshold, the fan is automatically turned on; when the CPU temperature is lower than the threshold, the fan is automatically turned off. That is, when the CPU temperature is low, the fan is not activated to avoid unnecessary waste.

[0044] S102, reading the temperature of the CPU based on the thermistor.

[0045] In this embodiment, a thermistor is used to detect the temperature of the CPU. The thermistor may be a thermistor with a sub-temperature coefficient, and its resistance value decreases as the temperature increases. It is judged whether the temperature of the CPU exceeds a preset temperature threshold by collecting the voltage at both ends of the thermistor....

Embodiment 2

[0051] On the basis of Embodiment 1, Embodiment 2 provides a server fan control method. In this method, it is judged whether the temperature of the CPU exceeds the preset temperature threshold by collecting the voltage across the thermistor. Correspondingly, the preset temperature threshold is also set in Voltage calibration. Specifically, a sliding resistor is set, and the voltage across the sliding resistor is collected as a preset temperature threshold.

[0052] like figure 2 As shown, a server fan control method provided in Embodiment 2 includes the following steps.

[0053] S201, reading the voltage across the sliding resistor.

[0054] S202, reading the voltage across the thermistor.

[0055] S203, judging whether the voltage across the thermistor is less than or equal to the voltage across the sliding resistor.

[0056] S204, if the voltage across the thermistor is less than or equal to the voltage across the sliding resistor, turn on the fan switch to start the fan;...

Embodiment 3

[0061] Embodiment 3 provides a server fan control device that specifically implements the above server fan control method.

[0062] like image 3 As shown, the server fan control device provided in Embodiment 3 includes a CPU temperature detector, a fan switch actuator, and a temperature processor.

[0063] CPU temperature detector: used to detect CPU temperature.

[0064] Fan switch actuator: It is electrically connected with the fan and is the switch of the fan.

[0065] Temperature processor: the input end of the temperature processor is electrically connected to the CPU temperature detector, and the output end is electrically connected to the fan switch actuator; when it is judged that the CPU temperature detected by the CPU temperature detector is higher than the preset value, the fan switch actuator is controlled Turn on to start the fan; when it is judged that the CPU temperature detected by the CPU temperature detector is lower than the preset value, control the fan ...

Abstract

The invention relates to the field of server fan control, and particularly discloses a server fan control method and device, a terminal and a storage medium. The CPU temperature is read based on the thermistor; judging whether the read CPU temperature is greater than or equal to a preset temperature threshold value or not; if the read CPU temperature is larger than or equal to the preset temperature threshold value, a fan switch is turned on, and a fan is started; if the read CPU temperature is smaller than the preset temperature threshold value, a fan switch is turned off, and the fan is stopped. The temperature of the CPU is read based on the thermistor, when the read temperature of the CPU is larger than or equal to the preset temperature threshold value, the fan is turned on, and otherwise, the fan is turned off. When the CPU heats to a certain degree, the fan is automatically started to dissipate heat of the CPU, the fan does not need to be started at the start of the server, that is, the fan does not work when the CPU does not heat, and waste of electric energy is greatly avoided.

Description

technical field [0001] The present invention relates to the field of server fan control, in particular to a server fan control method, device, terminal and storage medium. Background technique [0002] The rapid development of the Internet has also brought prosperity to the server market. A large number of data storage and calculations need to be completed by servers. Most of these servers need to run 24 hours a day, so the heat generated can be imagined. The usual practice is to use air conditioners to reduce the indoor temperature. At the same time, inside the server, professional heat dissipation design is also required, such as liquid cooling or fan heat dissipation. At present, the mainstream heat dissipation method is still fan heat dissipation. [0003] At present, the fan starts to work when the server is started, and the control of the fan is only to control its speed, and the fan speed is adjusted by adjusting the duty cycle of the square wave through PWM pulse w...
