The application relates to the technical field of
power mode recognition, in particular to a
power equipment fault detection method and
system based on a
deep learning network, which comprises the following steps: collecting and preprocessing
multimodal data such as power
time series and equipment images; monitoring the resource state of an
edge node in real time, and adjusting the configuration parameters of a lightweight
feature extraction model according to a preset rule; adopting a bidirectional cross-
modal attention mechanism, calculating query, key and value representation and attention weight, dynamically weighting and fusing projection feature vectors of different
modes, and generating a unified fault representation vector; calculating a
fault probability by using the representation vector, and adaptively optimizing the parameters of a probability calculation model through online
incremental learning; finally, calculating a task priority, and determining whether data is uploaded to a higher-level
system for more detailed analysis according to the priority and a real-time resource state. The application can effectively improve the real-time performance, accuracy and
adaptive capacity of edge-end
power equipment fault detection.
