Problems solved by technology

In this case, if you still use the existing method to evaluate the service life of the PSU, and replace the PSU when the estimated service life of the PSU is exhausted, it will not only increase the capital investment of the server for the PSU, but also increase the server life cycle operation and maintenance cost
At present, there is no effective solution to the above problems

Embodiment approach

[0075] As a preferred implementation, the above prediction method also includes:

[0076] Burn the first factory life value, the second factory life value and the third factory life value corresponding to the fan, electrolytic capacitor and MOSFET to EEPROM in advance;

[0077] The first factory life value, the second factory life value and the third factory life value are retrieved from the EEPROM, and according to the first factory life value, the second factory life value, the third factory life value, the first life value, the second The life value and the third life value respectively determine the remaining service life of the fan, the electrolytic capacitor and the MOSFET in the current operating state, and obtain the first remaining life value, the second remaining life value and the third remaining life value;

[0078] If the shortest life value among the first remaining life value, the second remaining life value and the third remaining life value is less than a pres...

Abstract

The invention discloses a method for predicting the service life of a PSU. The method comprises the steps: obtaining the service life estimation functions of a fan, an electrolytic capacitor and an MOSFET in the PSU; obtaining the operation load value of the PSU and the first operation temperature value and the target operation speed of the fan; determining a first service life value of the fan according to the operation load value, the first operation temperature value and the target operation speed based on the service life estimation function of the fan; respectively acquiring a second operation temperature value and a third operation temperature value of the electrolytic capacitor and the MOSFET; determining a second life value of the electrolytic capacitor according to the operation load value and the second operation temperature value based on the life estimation function of the electrolytic capacitor; determining a third service life value of the MOSFET according to the operation load value and the third operation temperature value based on the service life estimation function of the MOSFET; and determining the shortest life value in the three life values as the service life of the PSU. Through the method, the service life of the PSU can be evaluated relatively accurately.

Description

technical field [0001] The present invention relates to the technical field of servers, in particular to a method, device, equipment and medium for predicting the service life of a PSU. Background technique [0002] A PSU (Power Supply Unit, power supply unit) is used as a power supply module of the server, and the service life of the PSU is an important index to ensure the normal operation of the server. There are many key components installed in the PSU, such as: fans, electrolytic capacitors, and MOSFETs (Metal Oxide Semiconductor Field Effect Transistor, Metal Oxide Semiconductor Field Effect Transistor) and so on. In the prior art, when predicting the service life of a PSU, the service life of the whole PSU is generally determined as the service life of the device with the shortest service life among the three internal fans, electrolytic capacitors and MOSFETs. [0003] Since the service life of the PSU is closely related to its own operating state, in the prior art, i...
