AI Technical Summary

Technical Problem

Existing methods for detecting anomalies in drainage pipe networks suffer from problems such as strong dependence on fixed thresholds, poor model adaptability, and frequent false alarms and missed alarms, making them difficult to adapt to complex drainage system environments.

Method used

Based on an adaptive soft measurement strategy, upstream and downstream sensor data are selected as input features through pipeline topology analysis and sensor data mutual information analysis. The KAN-Attention deep learning algorithm is applied to construct a soft measurement model. Combined with the dynamic search of confidence intervals and the dynamic moving window method of probability density function, sensor anomaly detection is achieved.

Benefits of technology

This improves the accuracy and robustness of sensor anomaly detection, reduces false alarm and false negative rates, and ensures the long-term effectiveness of the detection method.
