AI Technical Summary

⚠Technical Problem

Existing technologies suffer from insufficient reliability of single-modal perception, lack of interpretability in diagnostic results, decoupling of robot motion from detection tasks, and disconnect between data acquisition and maintenance decisions, resulting in low anomaly detection rates and slow responses during equipment inspections.

⚗Method used

A multimodal data fusion method is adopted. By determining the characteristics and dynamic weights of each modality, and combining the device semantic graph and physical mechanism graph for joint reasoning, the path and posture of the inspection robot are adjusted, re-inspection data is collected, and abnormal event packages are output for adjusting operation and maintenance decisions and inspection strategies.

🎯Benefits of technology

It improved the anomaly detection rate, enhanced the interpretability of diagnosis and the ability to suppress false alarms, formed a closed loop of anomaly detection, diagnosis, re-examination and output, reduced false alarms and missed detections, and reduced the need for maintenance personnel to visit the site repeatedly and conduct inefficient verification.

Abstract

This invention provides a method for safe operation and maintenance of power equipment based on an inspection robot, and the inspection robot itself, relating to the field of equipment inspection technology. The method includes: determining the features of each modality of data and the corresponding dynamic weights of each modality of data based on multimodal data from a target observation area; determining multimodal fusion features based on the dynamic weights of each modality of data and the corresponding features of each modality of data; mapping the multimodal fusion features to a preset equipment semantic map and physical mechanism map and performing joint reasoning to obtain the root cause explanation result of the abnormal event and a comprehensive abnormality score; adjusting the path and posture of the inspection robot according to the re-inspection action, and re-collecting the multimodal data as re-inspection data. This invention improves the anomaly detection rate, diagnostic interpretability, single inspection information density, and operation and maintenance response efficiency.
