  • REAL-TIME PREDICTION AND REGULATION METHODS AND SYSTEMS OF PRODUCT QUALITY BASED ON PROCESS DYNAMIC PATTERN
    Publication number: 20240028016
    Abstract: The invention provides real-time prediction and regulation methods and systems of product quality based on a process dynamic pattern. The prediction method includes: constructing a state space probability model of quality pattern dynamic motion equation; calculating a probability density function distribution of a quality pattern according to the probability model; performing optimized learning on parameters of the state space probability model of quality pattern dynamic motion equation according to the probability density function distribution, to obtain optimal model parameters and an optimized state space probability model of quality-pattern dynamic motion equation; and performing online prediction on product quality indicators based on the optimized state space probability model.

  • Multilevel pattern monitoring method for industry processes
    Patent number: 11120350
    Abstract: The present invention discloses a multilevel pattern monitoring method for a process industry process and belongs to the fields of industrial production and processing. The multilevel pattern monitoring method comprises the steps: dividing an industry process into a plurality of levels from the view of patterns, selecting a different key performance index for each level, acquiring operating data relevant to the key performance index, identifying the pattern of each level, and proposing a pattern monitoring method for each level based on a data driven method to realize pattern monitoring in the industry process.
