The application relates to the technical field of
industrial equipment monitoring and defect diagnosis, and particularly discloses a data-
adaptive equipment production process defect identification method and
system. A multi-dimensional
delay dynamic benchmark is constructed, and a joint decision based on a
delay gradient and fluctuation entropy is adopted to realize intelligent classification and rapid routing of sudden failures, environmental disturbances and composite hidden dangers. The
system adopts a three-layer nested diagnosis mechanism of abnormal dimension screening, cause-effect chain tracing and defect
mode matching to accurately locate the
root cause and drive a three-order
adaptive response closed loop of instantaneous inhibition, parameter compensation and
model correction to minimize production interruption. Meanwhile, the
system periodically calculates a
production line health index to realize self-evaluation and collaborative optimization of key parameters, so that the monitoring model can continuously evolve with changes in the
equipment state and the environment, and finally form an integration of real-time sensing, intelligent diagnosis and
adaptive optimization, thereby significantly improving the defect identification accuracy,
system stability and overall operation efficiency.
