The invention provides a prediction model construction method and
system for personalized equipment operation and maintenance, and relates to the technical field of
data processing, and the method comprises the steps: collecting equipment operation data and environment data, extracting the change characteristics of the equipment operation state, carrying out the
correlation analysis of the environment data based on historical equipment fault records, and obtaining a prediction model. Performing normalization
processing, performing
time sequence analysis, generating a joint
feature matrix, segmenting the joint
feature matrix into time slices of a fixed window according to a
time sequence, classifying the time slices into a
normal state and an abnormal state, performing feature contribution degree analysis, generating a feature weight matrix, and performing
feature extraction; re-combining the equipment features in the time slice
feature data set with the environment factors according to feature weights, generating fusion
feature data layer by layer, performing
supervised learning training on the fusion
feature data, constructing an equipment prediction model, and outputting the equipment prediction model as a prediction model of personalized equipment operation and maintenance; according to the invention, the operation and maintenance effect of personalized equipment is improved.
