Method and device for dynamically adjusting maintenance strategy, terminal and computer storage medium

Abstract

The invention discloses a method and device for dynamically adjusting a maintenance strategy, a terminal and a computer storage medium. The method comprises the steps: carrying out the distribution law analysis of fault causes of all maintainable parts of equipment through the historical maintenance data of the equipment, so as to obtain the static reliability; If the newly added inspection and maintenance data is obtained, analyzing the newly added inspection and maintenance data and historical inspection and maintenance data to obtain dynamic reliability; Calculating a difference value between the dynamic reliability and the static reliability; And if the difference value exceeds a preset threshold value, utilizing newly-added maintenance data to carry out analysis so as to dynamically adjust an existing maintenance strategy of each maintainable part. According to the technical scheme provided by the invention, the deviation condition of the equipment reliability can be reflected bythe difference value between the dynamic reliability and the static reliability, the maintenance strategy of the equipment is optimized in real time by carrying out real-time reliability analysis andreliability difference value analysis on the equipment and utilizing difference value early warning, so that maintenance resources and the like are reasonably distributed.

Description

technical field [0001] The present invention relates to the technical field of equipment failure, in particular to a method, device, terminal and computer storage medium for dynamically adjusting maintenance strategies. Background technique [0002] For the RCM (reliability-centered maintenance) method commonly used internationally, on the one hand, because the failure mode and impact analysis determined by its analysis method is based on the analysis of equipment functions, the key to maintenance tasks is at the level of equipment rather than At the level of the repairable unit below the equipment, this leads to no further connection between the maintenance task and the actual faulty repairable unit, which often leads to the inability to perform the maintenance task and unclear affiliation of the equipment failure when the maintenance task is performed. [0003] On the other hand, the fault analysis of the RCM method is only qualitative analysis, but cannot be quantitativel...
