AI Technical Summary

Technical Problem

Existing reactor temperature monitoring technologies suffer from several drawbacks: contact temperature sensing elements cannot reflect the overall temperature distribution of the reactor wall, have delayed response and are prone to corrosion; infrared thermal imaging data is large and susceptible to noise interference, resulting in low efficiency and frequent misjudgments during manual interpretation; and image processing and machine learning methods have poor adaptability and unsatisfactory recognition results.

Method used

Anisotropic weighted gradient calculation is used, combined with image entropy value and historical data analysis, to screen key pixels, and the temperature status is determined by fusing feature vectors through an LSTM model.

Benefits of technology

It significantly improves the accuracy and reliability of reactor temperature monitoring, reduces noise interference, adapts to different operating conditions, and reduces misjudgments and missed judgments.
