| Abstract:The three-dimensional hierarchical detection method of bus protection device fault based on knowledge base and panoramic image matching algorithm is studied to detect bus protection device fault reasonably and ensure safe and stable operation of bus protection device. The knowledge base construction level is based on information from failure cases, troubleshooting manuals and other information, designs relational knowledge, and designs 3D model index knowledge through panoramic image acquisition, feature extraction and matching, and constructs the knowledge base after classification; The inference control level uses the fuzzy hypothetical inference algorithm in the inference engine, takes the fault knowledge in the knowledge base as the effective basis, implements the effective inference according to the fault facts or evidence provided by the user, and obtains the corresponding fault diagnosis results; The 3D visualization level uses PHP language, builds a Web server, designs a 3D visualization back-end program, and presents the 3D visualization results of fault detection. The experimental results show that this method can better realize the three-dimensional hierarchical fault detection of bus protection device, and the fault detection results are consistent with the actual fault conditions, which can better meet the actual work needs. |
