[0031] The combined diagnostic model includes two parts, the primary diagnostic model and the secondary diagnostic model. From the process, it contains training process and diagnosis process. like figure 1 As shown, the primary sample data formed by the original data is input to the Naive Bayesian classifier, the RVM fault diagnosis model, the diagnosis model based on the physical meta-theory and the cloud model, and these models are trained; the diagnosis results of the diagnosis model group form a secondary The secondary data is input into the RVM fault diagnosis model to train the model. After the training, the measured oil chromatogram data is input into the naive Bayesian classifier, the RVM fault diagnosis model, the diagnosis model based on the physical element theory and the cloud model for the initial diagnosis, and the diagnosis results of the diagnosis model group form the secondary data, through The RVM fault diagnosis model performs secondary diagnosis, and fina...
