Abstract

The present invention provides a method for classification of associated parameter faults based on big data fusion clustering analysis. The fault classification method of the present invention selects fault data according to the interpretation rules from the massive data of equipment operation, and performs supervised machine autonomous clustering , to form the automatic classification results of associated parameter faults, which can solve the problem that the current equipment fault diagnosis is overly dependent on the expert knowledge base, while ignoring the correlation between the parameters of the deep nonlinear coupling between subsystems, and the massive effective The problem that the data has not been well mined and utilized; at the same time, because the implementation of the fault classification method of the present invention does not need to rely on the accurate physical modeling of the object equipment, it avoids the difficulty of traditional complex systems that are difficult to model, and realizes the problem based on massive The intelligent classification of faults and the analysis of associated parameters by data mining have the ability to classify faults with controllable accuracy.
