Abstract

The invention relates to the technical field of heat dissipation of servers, and provides an intelligent fan regulating method and system applied to universal fan types. The method comprises the stepsthat systematic deviation E and a deviation variation rate value EC are calculated; the systematic deviation E and the deviation variation rate value EC are subjected to fuzzing processing, and threecorrections of sigma Kp1, sigma Ki1 and sigma Kd1 of PID control parameters of a PID control algorithm are calculated and obtained; PID parameters of Kp, Kd and Ki are generated; the PID parameters of Kp, Kd and Ki are designed as weighted values of a PID control algorithm of a PID controller, and a control signal used for intelligently regulating the rotational speed of a fan is generated, therefore PID intelligent regulating of a server fan is achieved, manual adjusting wasting time and labor is avoided, and it is ensured that all elements and devices of the server work within a safe temperature value range.

Description

technical field [0001] The invention relates to the technical field of server heat dissipation, in particular to an intelligent fan control method and system applied to general-purpose models. Background technique [0002] With the development of new technologies such as cloud computing and big data, the bandwidth and capacity requirements of data storage are getting higher and higher, and the computing speed and amount of computing of processors are also increasing, resulting in the temperature of various components such as memory and hard disk. The heat dissipation of electronic devices has become a very hot issue at present, and the society's requirements for power consumption are getting lower and lower, and energy saving is a mainstream trend at present. How to effectively reduce the high temperature of each electronic component and reduce the power consumption of the fan wall, and satisfy the optimal power consumption of the whole machine is a technical problem that ne...
