The monitoring and control link of the fan speed of the server is mainly composed of the following links: First, the BMC collects the temperature register information of key parts and key components of the motherboard through the I2Cbus, and then converts the register value inside the BMC to form a temperature register that we can identify. "Celsius"; the second is to integrate the heat dissipation control strategy into the BMC to define how many revolutions the fan speed needs to reach when the collected temperature reaches a certain control point to ensure the current heat dissipation; the third is to control the fan inside the BMC Based on the monitored temperature information, combined with the heat dissipation strategy, it will output a PWM (Pulse Width Modulation: Pulse Width Modulation) signal to control the fan speed; the monitored components included in the heat dissipation strategy include CPU, memory, hard disk, air inlet, and air outlet etc. The temperature of the CPU and memory is not directly read by the BMC, but needs to be directly monitored by the ME in the south bridge, and the BMC then reads the information in the ME. This will cause the temperature of the CPU and memory to drop if the ME fails. Unable to read; and in the current heat dissipation strategy, if the CPU and memory temperature cannot be read, the fan will run at full speed, resulting in high power consumption and loud noise

The invention provides a fan control method. The fan control method comprises the following steps: reading current air inlet temperature information and current CPU temperature information; judging whether an ME has a fault or not according to the reading condition of the current CPU temperature information; if the ME has a fault, switching to a fault strategy so as to determine a current PWM value by using an adjustment relationship between the air inlet temperature and the PWM value according to the current air inlet temperature information; and controlling the rotating speed of a fan by utilizing the current PWM value. When the BMC determines that the ME has the fault, it is switched to the heat dissipation strategy in a fault state, and the current PWM value is determined according tothe current air inlet temperature information by utilizing the adjustment relationship between the air inlet temperature and the PWM value so as to control the rotating speed of the fan by utilizing the current PWM value, thereby avoiding the problems of high power consumption and noise caused by full-speed operation of the fan due to ME faults in related technologies. The invention further provides a fan control device, electronic equipment and a computer readable storage medium, which all have the above beneficial effects.
Description
technical field [0001] The present application relates to the technical field of fan control, and in particular to a fan control method, a fan control device, electronic equipment, and a computer-readable storage medium. Background technique [0002] During the operation of the server, if the ambient temperature is too high, the server will work in a high temperature environment as a whole. At this time, the temperature of the core components such as the CPU will be higher. When the temperature of the CPU reaches a certain height, the server will reduce the frequency. , which seriously affects the computing performance of the server; if the temperature continues to rise, the server will shut down abnormally, and the consequences caused by this will be customer business interruption and data loss, resulting in unpredictable losses. [0003] A BMC (Baseboard Management Controller: Baseboard Management Controller) is usually used in a server system to monitor and manage the hea...
