The invention belongs to the technical field of
data analysis, and provides a
dynamic data acquisition and intelligent
screening analysis method and
system based on multi-dimensional
feature fusion. The method comprises the steps of multi-dimensional working data collection, abnormal problem judgment, abnormal process matching, potential problem equipment determination, secondary data collection, abnormal multi-dimensional data screening and abnormal
data analysis model analysis. According to the invention, the abnormal production identification sensitivity is improved through the abnormal judgment model; through the default frequency and the
fault analysis frequency, the data volume during the abnormal
traceability period is optimized, and the abnormal
data analysis reliability is improved; through abnormal multi-dimensional data screening, the
data structure is optimized, the proportion weight of abnormal potential data is improved, and the model calculation amount is reduced; and through the abnormal data analysis model, the early-stage manual labeling process is avoided, and the universality and flexibility of the model are improved.
