AI Technical Summary

Technical Problem

When evaluating the safety performance of the cross-span segment of the transmission line, the prior art ignores the characteristics of the cross-span segment itself and the complex relationship between different monitoring data, resulting in the limitation of the accuracy and timeliness of the evaluation results.

Method used

By obtaining the target type of cross-span segments in the transmission line, a cross-span structure knowledge graph in the preset digital twin three-dimensional model database is built, monitoring structure data is obtained, and security evaluation is performed through the cross-span segment structure safety model to output security evaluation results.

Benefits of technology

The accuracy and timeliness of safety performance evaluation are improved. By building a structural knowledge graph and a comprehensive performance evaluation model, historical data and monitoring data are systematically integrated to comprehensively evaluate the overall safety of cross-span segments.
