Embodiment Construction

[0028] Please refer to figure 1 , is an application structure diagram of the fan speed adjustment system 100 of the present invention. The fan speed adjustment system 100 runs in a server 1 . The server 1 includes a CPU (Central Processing Unit, central processing unit) 10 , and the server 1 is also provided with a temperature sensor 11 and a fan 12 . The fan 12 is used to dissipate heat from the CPU 10 . The temperature sensor 11 is used to detect the temperature of the CPU 10 .

[0029] The fan speed adjustment system 100 includes several modules, which are a series of program instruction segments that can be executed by the CPU 10 and can complete predetermined functions. The several modules include a sampling module 101 , a creation module 102 , an acquisition module 103 , a calculation module 104 and an adjustment module 105 . The several modules are stored in the server 1 .

[0030] The sampling module 101 is used for sampling the CPU utilization rate, the CPU tempe...

Abstract

The invention provides a fan speed adjustment system and method. The system comprises a sampling module, a creating module, an acquisition module, a calculation module and an adjustment module, wherein when a temperature sensor is normal, the CPU usage rate, the temperature value and the fan speed value are sampled; a usage rate function, a temperature function and a speed function are created according to the sampled usage rate, the temperature value and the speed value; the creating module further creates a first function between the temperature value and the speed value according to the temperature function and the speed function; the creating module further creates a second function between the usage rate and the temperature value according to the usage rate function and the temperature function; the creating module further creates a third function between the usage rate and the speed value according to the first function and the second function; the acquisition module acquires the CPU usage rate in real time; the calculation module calculates a corresponding fan speed value according to the usage rate acquired in real time and the third function; the adjustment module adjusts the current fan speed into a speed value obtained by calculation. According to the fan speed adjustment system and method, the fan speed can be adjusted normally under the condition that the temperature sensor is damaged.

Description

technical field [0001] The invention relates to a fan rotation speed adjustment system and method. Background technique [0002] Nowadays, the application of servers is more and more extensive, and the scale of servers in the IDC (Internet Data Center) computer room is getting larger and larger. So many servers will generate a lot of heat when they are working, which will increase the ambient temperature and affect the normal work of the servers. Among them, The CPU is the main source of heat generation. In order to dissipate heat for the CPU, a temperature sensor and a cooling fan are usually installed in the server. The temperature sensor detects the temperature of the CPU, and the fan adjusts its rotational speed according to the temperature detected by the temperature sensor. However, some temperature sensors may be damaged. At this time, the fan cannot normally adjust the speed, which will cause the CPU temperature to be too high and affect the normal operation of the ...
