Microcomputer-controlled AC/DC power system fault judgment method, system and equipment

Abstract

The invention belongs to the field of deep learning and forecasting technology, and specifically relates to a microcomputer-controlled AC / DC power supply system fault judgment method, system and equipment, aiming to solve the problem that the existing fault analysis method fails to identify the implicit connection between components are counted and fail to notice problems with types of failures not found by humans. The present invention includes: obtaining the environmental information and operating parameters of each part of the entire AC / DC power supply system, and extracting the relationship between each parameter and the fault type through the Apriori algorithm and convolutional neural network, and diagnosing the implementation data to obtain the judgment result, And recommend a maintenance plan based on the judgment result. The present invention obtains the implicit relationship between components, thereby improving the accuracy of fault analysis, realizing the automatic addition of faults that may be caused by factors ignored only by manual experience, improving the versatility of fault analysis, and Increased scalability, new failures can be discovered and proactively countered.
