Problems solved by technology

[0004] In the existing fan life detection process, the server temperature is usually detected to determine whether the fan has reached the life threshold, and the fan life cannot be directly detected. When the temperature of the server is detected to exceed the normal range, it is determined that the corresponding fan has reached the threshold. Life threshold, need to be replaced, however, at this time the server may have been damaged due to temperature rise, there is a big security risk

Embodiment 1

[0053] Such as figure 1 As shown, this embodiment provides a method for predicting the life of a fan, including the following steps:

[0054] S1: Set a temperature detection point at the air outlet position of the server to monitor the ambient temperature of the fan.

[0055] S2: Obtain the service life of the fan at different temperatures and speeds, and obtain the reference value of the service life of the fan.

[0056] Specifically, if the life of the fan at full speed at 50 degrees Celsius is A hours, the life of the fan at full speed at 40 degrees Celsius is 2A hours, and the life of the fan at full speed at 30 degrees Celsius is 4A hours. If the rotation speed is reduced by 10%, the service life is increased by B times; then the life reference value of the fan is set to 4A.

[0057] S3: When the server is running, obtain ambient temperature information and rotational speed information of the fan through the BMC.

[0058] Specifically, during the running of the server, t...

[0089] This embodiment discloses a fan life prediction device, which includes a processor and a memory; wherein, when the processor executes the fan life prediction program stored in the memory, the following steps are implemented:

[0090] 1. Set a temperature detection point at the air outlet position of the server to monitor the ambient temperature of the fan.

[0091] 2. Obtain the service life of the fan at different temperatures and speeds, and obtain the reference value of the service life of the fan.

[0092] 3. When the server is running, obtain the ambient temperature and speed information of the fan through the BMC.

[0093] 4. Determine the first life weight value of the fan according to the ambient temperature information of the fan, and determine the second life weight value of the fan according to the rotational speed information.

[0094] 5. Obtain the current running time of the fan through the BMC.

[0095] 6. Calculate the life consumption value of the fan...

Abstract

The invention provides a fan life prediction method, system and device and a readable storage medium, and the method comprises the steps: setting a temperature detection point at an air outlet position of a server, so as to monitor the environment temperature of a fan; the service life of the fan at different temperatures and rotating speeds is obtained, and the service life reference value of the fan is obtained accordingly; when the server runs, environment temperature information and rotating speed information of the fan are obtained through the BMC; determining a first service life weight of the fan according to the environment temperature information of the fan, and determining a second service life weight of the fan according to the rotating speed information; obtaining the current running duration of the fan through the BMC; according to the first service life weight, the second service life weight and the operation duration, the service life consumption value of the fan in this operation is calculated; updating the life reference value according to the life consumption value; if the service life reference value is lower than the service life threshold value, warning information is sent out through the BMC. According to the method, the service life of the fan can be predicted by utilizing the chip temperature and the holding time output by the BMC, and system warning is carried out.

Description

technical field [0001] The present invention relates to the technical field of fan detection, and more specifically relates to a fan life prediction method, system, device and readable storage medium. Background technique [0002] High-performance servers use fans for auxiliary heat dissipation, and the fans are often placed at the rear of the system at the air outlet to receive the hot air blown out. The high-speed operation of the fans at high temperatures will cause the loss of fan life. There will be a risk of failure, and there is a risk of high temperature for the system to operate. [0003] At present, large-scale Internet customers will have requirements for the MTBF (mean time between failures) of the fan. For example, some customers require the fan to run for 50,000 hours at an ambient temperature of 60C. Therefore, it is necessary to detect the service life of the fan in real time, so as to ensure the cooling performance of the server. [0004] In the existing f...
