AI Technical Summary

Technical Problem

Existing technologies fail to fully utilize the interrelationships between sensors in hydrogen pipeline network flow monitoring, resulting in a high false alarm rate when a single sensor fails, increasing operation and maintenance costs, and lacking flexibility and accuracy.

Method used

A method for detecting flow anomalies in hydrogen pipeline networks based on dual-dimensional features is adopted. By adaptive slicing in the time and channel dimensions, a time feature extractor, a spatial feature extractor, and a trunk feature extractor are used to capture the feature correlations within and between slices. Finally, a reconstruction network with multiple hidden layers of different feature scales is used to reconstruct and score anomalies under multiple views.

Benefits of technology

It enables accurate identification of abnormal flow data in industrial hydrogen transmission pipelines, improves industrial safety management, and ensures the stable operation of hydrogen transmission pipelines.
