AI Technical Summary

Technical Problem

Existing fault diagnosis methods for gas pressure regulators are difficult to achieve online monitoring and multi-category fault identification. In particular, there is insufficient research on the enhancement of weak fault features, and the model generalization ability is insufficient, making it unable to meet the diagnostic needs under complex operating conditions.

Method used

By employing a differential perception adversarial decoupling method, an end-to-end fault diagnosis model is constructed using dual-channel time-series data. By utilizing outlet pressure and instantaneous flow signals, combined with differential perception feature enhancement and operating condition adversarial branching, deep decoupling of fault features and operating condition features is achieved, thereby improving diagnostic accuracy and robustness.

Benefits of technology

It achieves high-precision and robust fault diagnosis of gas pressure regulators, and can monitor and identify multiple types of faults online. It is especially effective in diagnosing minor faults under variable flow load conditions, improving the model's generalization ability and diagnostic accuracy.
