METHOD FOR THE AUTOMATIC PROCESS MONITORING AND PROCESS DIAGNOSIS OF A PIECE-BASED PROCESS (BATCH PRODUCTION), IN PARTICULAR AN INJECTION-MOLDING PROCESS, AND MACHINE THAT PERFORMS THE PROCESS OR SET OF MACHINES THAT PERFORMS THE PROCESS

摘要

The invention relates to a method for the automatic process monitoring and/or process diagnosis of a piece-based process, in particular a production process, in particular an injection-molding process, comprising the steps: a) performing an automated reference finding in order to obtain reference values (r ₁... r _n) from values (x ₀... xsb / _j) of at least one process variable; b) performing an anomaly detection on the basis of the reference values (r ₁... r _n) found in step (a); • c) performing an automated cause analysis and/or an automated fault diagnosis on the basis of a qualitative model of process relationships and/or on the basis of dependencies of various process variables on each other.
