Problems solved by technology

During this period of time, the speed of the fan is not affected by the temperature of the CPU. The general heat dissipation design is to set the speed of the fan to a maximum speed, which will cause problems of high noise and high power consumption.
Or use a fixed speed, so there will be a risk of heat dissipation
The BMC management system is a relatively complex system. When the BMC encounters a fault, the BMC may crash. If the BMC crashes, the fan may not be controlled.
In this way, the normal operation of the system cannot be guaranteed

Embodiment Construction

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] The invention includes: (1) a temperature acquisition module; (2) a fan control module; (3) a BMC management module (4) a circuit switching module; (5) a fan module. A total of 5 parts, the temperature acquisition module, fan control module, line switching module, and fan module form line 1; the BMC management module, line switching module, and fan module form line 2.

[0021] After the server is powered on, line 1 immediately starts to work, and line 2 is in the initialization state. The temperature acquisition module compares and analyzes the temperatures of multiple temperature points collected, and transmits a temperature with the worst working condition to the fan control module. Because the first power on, the priority of line 1 is higher than that of l...

Abstract

The invention provides a device and method for automatically controlling a fan after a server is powered on and relates to the technical field of computer servers. The device comprises a temperature collection module (1), a fan control module (2), a BMC management module (3), a circuit switching module (4) and a fan module (5). A cooling system is monitored and controlled after the server is just powered on through an AC and before a BMC management chip does not complete initialization; meanwhile, the rotation speed of the fan is controlled by automatically switching between two circuits; accordingly, the reliability of heat dissipation of the system can be guaranteed, and consumption of extra power caused by the constant high rotation speed can be avoided.

Description

Technical field [0001] The invention relates to the technical field of computer servers, in particular to a device and method for automatically controlling a fan when the server is powered on. Background technique [0002] After the system is normally powered on, the BMC management chip needs a period of time to initialize, generally ranging from tens of seconds to several minutes. During this period of time, the fan's speed is not affected by the CPU temperature. The general heat dissipation design is to set the fan's speed to a maximum speed, which causes problems of high noise and high power consumption. Or use a fixed speed, so there is a risk of heat dissipation. The BMC management system is a relatively complex system. When the BMC encounters a failure, the BMC may crash. If the BMC crashes, the fan will not be controlled. In this way, the normal operation of the system cannot be guaranteed. Summary of the invention [0003] In order to solve this problem, the present inv...
