Aiming to address the challenges of visual indistinguishability and sample imbalance in identifying missing bolts in transmission lines, we propose a method that relies on graph knowledge reasoning. First, the knowledge expression module learns class representations of various bolts with discriminative characteristics. Then, the label co-occurrence information is extracted through the analysis of correlations among bolt types in the bolt dataset. Finally, the knowledge inference module performs dissemination and enhancement of graph knowledge by taking the category representation as an input feature and using static and dynamic graphs, representing label co-occurrence information, as adjacency matrices. This leads to the identification of missing bolts. In the experimental phase, six bolt types on three selected fittings were selected as test subjects. The results show that our method outperforms other methods in identifying missing bolts, improving accuracy by 9.13% compared to the original model. The results of the ablation experiment demonstrate that the category representation, static graph, and dynamic graph information of bolts extracted in our method all contribute to improved recognition of missing bolts.
