March 24 News, the information from the State Intellectual Property Office shows that Yunda Energy Technology Group Co., Ltd. has applied for a patent titled “Multimodal Information-Based Wind Turbine Fault Handling Method, Device, Equipment, and Medium,” with authorization announcement number CN121167314B, granted on March 20, 2026. The application publication number is CN121167314A, with application number CN202511714475.1, published on March 20, 2026, and the application was filed on November 21, 2025. The inventors are Hu Mengting, Wang Lin, Zhu Changjiang, Chen Jing, Zhang Wenqing, Wu Luyu, and Sun Jingyu. The patent agency is Beijing Jiajia Intellectual Property Agency Co., Ltd., with patent agent Yang Dandan. The classification codes include G06F18/214, F03D17/00, G06F18/20, G06F18/15, G06F18/25, G06N3/042, G06N3/045, G06N3/0464, G06N3/092, and G06N3/096.

The patent abstract discloses a method, device, equipment, and medium based on multimodal information for fault handling in wind turbines, involving the following steps: preprocessing multimodal fault-related information of wind turbines to build a multimodal fault database; constructing a multimodal joint semantic embedding space based on this database, and combining a cross-modal hierarchical attention mechanism to determine an optimized current multimodal large model; dynamically constructing a three-dimensional knowledge graph based on the joint semantic embedding space, and during the process of fault propagation path recognition using reinforcement learning with the knowledge graph, identifying the path recognition result for newly occurring target wind turbine fault events; generating a structured decision report based on the path recognition result and the current multimodal large model to trigger maintenance operations, and generating a correction feedback report based on corresponding maintenance records and the current multimodal large model. This approach can address deficiencies in existing solutions and improve the accuracy of fault handling decision-making.
