AI Technical Summary

Technical Problem

Existing fault monitoring solutions for coal mine conveyor belts rely on manual inspections or local sensors, which are inefficient, have poor real-time performance and coverage blind spots, making it difficult to achieve accurate and reliable fault early warning. In particular, electrical sensors are susceptible to electromagnetic interference in complex underground environments.

Method used

By acquiring the associated acoustic signal and motor current signal of the belt conveyor, using optical fiber sensing to collect and convert the signal, and combining the feature extraction module, feature fusion module and fault classifier built by parallel LSTM layer, weights are dynamically generated, and fault identification and early warning are performed based on environmental parameters.

Benefits of technology

It improves the accuracy and timeliness of fault early warning, enhances the model's adaptability to different environments, and improves the intelligence level and applicability of fault early warning.
