| Abstract: | Considering the process high dimensionality, multi -operation, time -variant characteristics, and unknown mode duration, the article proposes the multiple mode monitoring algorithm based on the gaussian mixture model. It also proposes the offline data classification algorithm aiming at the problem that offline data has no modal tag. For online data to corresponding modal type of problem, online data mo- dal identification algorithm is put forward. And on the basis of the above methods establishing the model of multimodal process monitoring in continuous annealing line as the background, the effectiveness of the algorithm was validated by actual production data. |
