The invention relates to the technical field of
industrial equipment monitoring and defect diagnosis, and particularly discloses a data self-
adaptive equipment production process defect identification method and
system. By constructing a multi-dimensional
delay dynamic reference and based on a joint decision of a
delay gradient and a fluctuation entropy, intelligent classification and fast routing of sudden faults, environmental disturbance and composite hidden dangers are realized. According to the
system, a three-layer nested diagnosis mechanism of abnormal dimension screening, causal chain tracing and defect
mode matching is adopted, a
root cause is accurately positioned, and a three-order
adaptive response closed loop of instantaneous suppression, parameter compensation and
model correction is driven so as to minimize production interruption. Meanwhile, the
system periodically calculates the
health index of the
production line and realizes self-evaluation and collaborative optimization of key parameters, so that a monitoring model can continuously evolve along with the change of the
equipment state and the environment, and finally, integration from real-
time perception and intelligent diagnosis to
adaptive optimization is formed, and the defect identification accuracy, the
system stability and the overall operation and maintenance efficiency are remarkably improved.
