AI Technical Summary
Existing resin production control systems suffer from both excessive alarms and missed alarms during non-steady-state phases, failing to distinguish between normal drastic changes and abnormal runaway trends. Single-variable monitoring leads to misjudgments of faults such as sensor drift, increasing safety risks in the production process.
By acquiring historical golden batch data of the resin production process, a standard reference curve is constructed, and the local transient response energy and coupling deviation verification coefficient of real-time production data are calculated. Combining the first and second derivatives, a comprehensive anomaly score is constructed to achieve adaptive monitoring and multivariate coupling verification.
It achieves adaptive monitoring under all operating conditions, improves the safety of the resin production process, prevents missed and false alarms, accurately identifies hidden faults such as sensor drift or minor leaks, and simplifies the judgment of operators.
