Classification method and system for metadata of power system and storage medium

The invention provides a power system metadata classification method and system and a storage medium, and relates to the technical field of power information.The power system metadata classification method comprises the steps that image metadata, audio metadata and text metadata of a power system are obtained; processing the image metadata through the trained image convolutional neural network model, and generating an image classification result; processing the audio metadata through the trained GRU model to generate an audio classification result; processing the text metadata through the trained LSTM model to generate a text classification result; extracting classification labels in the image classification result, the audio classification result and the text classification result through a natural language algorithm; according to the classification label, obtaining image data, audio data and text data corresponding to the classification label; and sorting the classification labels and the image data, the au
