Specifically, the micro control unit may obtain a second temperature parameter of a hard disk, a CPU, and other components in the system, and determine a target device in the system. It is understood that the target device is a device that generates heat above a predetermined threshold. And then the input current parameter of the target device can be obtained. The preset threshold may be set according to an actual service scenario in a specific implementation, and is not specifically limited herein.

it should be noted that, a control algorithm inside the micro control unit may be utilized, and the second temperature parameter and the input current parameter are used as feedback signals to form a multi-loop negative feedback control system, which may output a corresponding second duty ratio.
It can be understood that, in the embodiment of the application, not only the temperature parameter but also the input current parameter of the device mainly generating heat can be obtained, and the electric energy can be converted into heat energy in the subsequent operation, so that the influence of the current on the temperature change can be predicted in advance, and the influence of the current on the temperature change can be avoided.
S104: and determining a target duty ratio by combining the first duty ratio and the second duty ratio, and controlling the rotating speed of the fan by using the target duty ratio.
In the embodiment of the present application, the target duty ratio may be determined and obtained by combining the first duty ratio and the second duty ratio, so as to output a corresponding control signal of the fan rotation speed according to the target duty ratio.
In a specific implementation, the determining the target duty ratio by combining the first duty ratio and the second duty ratio may specifically include: inputting the first duty ratio and the second duty ratio into a preset selector; and acquiring an output result of the preset selector, and determining the output result as a target duty ratio. The output result of the preset selector can be obtained and manually selected by the user terminal, specifically, the selection instruction can be sent through the preset instruction sending interface, and the preset selector can determine that the final output result is the first duty ratio or the second duty ratio according to the selection quality.
In a specific embodiment, after the target duty ratio is determined and the fan speed is controlled by using the target duty ratio, the target duty ratio and the current fan speed may be further visually displayed through a display interface, so that a user can clearly know the current fan speed.
According to the scheme, the fan rotating speed control method provided by the application comprises the following steps: acquiring a first temperature parameter of a key position of a system through a BMC (baseboard management controller), and determining a corresponding first duty ratio according to the temperature parameter; acquiring a second temperature parameter of a key position of the system and an input current parameter of a target device in the system through a micro control unit; determining a corresponding second duty cycle by using the micro control unit with the second temperature parameter and the input current parameter as feedback signals; and determining a target duty ratio by combining the first duty ratio and the second duty ratio, and controlling the rotating speed of the fan by using the target duty ratio. According to the method, the BMC and the micro control unit can be used for acquiring the required parameters respectively, the duty ratios corresponding to the BMC and the micro control unit are determined, the fan rotating speed can be controlled by combining the first duty ratio and the second duty ratio, the stability of a control system is improved, and the server equipment is guaranteed to have a good heat dissipation function.
The fan speed control scheme provided by the embodiment of the present application is described in detail by specific examples below. As shown in fig. 2, a temperature detection sensor is added to each component generating a large amount of heat, such as a current input terminal of a CPU, on the system board, and connected to the SMBUS bus; for each element generating larger heat, a current detection sensor is added at the current input end of the element and is also connected to the SMBUS bus. A MCU (micro controller Unit) chip supporting PTEC functions is placed on the system motherboard, and a selector Switch is further placed on the system motherboard.
Further, the SMBus bus for detecting the temperature is connected to the BMC, the BMC obtains the temperature parameter of the detection position through the SMBus bus, and the corresponding PWM0 is obtained through calculation by using a corresponding algorithm. The SMBus bus for detecting the temperature and the SMBus bus for detecting the current are connected to the MCU, and the MCU can obtain the temperature parameter of the detection position through the SMBus bus and can obtain the input current parameter of the device mainly generating heat. Furthermore, a multi-loop negative feedback control system is formed by using a PTEC (predictive Thermal Energy controller) control algorithm in the MCU and taking the temperature parameter and the current parameter as feedback signals, and corresponding PWM1 is output. Further, the PWM0 and the PWM1 are transmitted to the selector Switch, and the selection signal of the controller BMC determines whether the PWM0 or the PWM1 is finally transmitted to the fan, so that the final PWM fan control signal is output.
In the embodiment of the application, two schemes of controlling the rotating speed of the fan by using the BMC and the MCU can be compatible. The BMC can select the PWM0 signal output by the BMC to control the fan through setting the select signal, and can also select the PWM1 signal output by the MCU to control the fan, so that the robustness and the stability of the system are enhanced. And the MCU processes the input temperature coefficient and the input current coefficient, the current has corresponding foresight to the change of the temperature, and the duty ratio of the PWM can be effectively reduced through simulation comparison, so that the energy-saving effect can be realized.
