Problems solved by technology

The disadvantage of this method is that the fan speed will be higher than the actual speed requirement, and the fan speed will suddenly soar, causing obvious noise and power loss
However, the prediction of this algorithm has limitations and can only be adjusted according to changes in temperature, so there is a hysteresis for the direct cause - the change of power consumption, and the response of the fan will also be hysteresis. Sometimes it will lead to a change process of the fan, which will not only bring risks to the heat dissipation of the device, but also cause a large fluctuation in the power consumption of the whole machine

Abstract

The invention relates to a fan regulation and control method based on overall power consumption. The fan regulation and control method is characterized by comprising the following steps: S1: collecting temperature values of electronic elements and devices, and setting a boundary point C of the temperature values of the electronic elements and devices; S2: determining temperature stable time of theelectronic elements and devices, and setting a boundary point T of the temperature stable time of the electronic elements and devices; S3: collecting the power consumption value of a fan; S4: regulating and controlling a PID parameter according to the boundary point C of the temperature values of the electronic elements and devices and boundary point T of the temperature stable time of the electronic elements and devices, to realize increase or reduction of a rotary speed of the fan; and S5: regulating and controlling an initial rotary speed value of the fan according to the collected fan power consumption value.

Description

technical field [0001] The invention belongs to the technical field of server fan control, and in particular relates to a fan control method based on the power consumption of the whole machine. Background technique [0002] With the development of new technologies such as cloud computing and big data, the bandwidth and capacity requirements for data storage are getting higher and higher, and the computing speed and computing volume of processors are also increasing, resulting in various components such as memory, hard disk, and GPU. The temperature of the computer is also soaring, the heat dissipation of electronic devices has become a very hot issue at present, and the society's requirements for the power consumption of the whole machine are getting higher and higher, and energy saving is a mainstream trend at present. How to effectively reduce the excessive temperature of each electronic component and reduce the power consumption of the fan wall has become an urgent techni...
