The invention discloses a mining
equipment state prediction method based on digital twinning and multi-
modal fusion, and relates to the technical field of intelligent operation and maintenance, and the method comprises the steps: inputting a multi-
modal alignment working condition window sequence into a digital twinning mechanism link, carrying out the same-window ideal response deduction, outputting an ideal multi-
modal response, and constructing a twinning dynamic residual error; meanwhile, segmenting a residual structure event to generate a residual event token set; positioning a multi-
modal data fragment based on the residual event token set, executing cross-modal attention alignment, and performing topology propagation aggregation in combination with a mechanical topology observation mapping table to generate a topology constraint fusion table set; and inputting the topological constraint fusion table set into the graph neural network, carrying out
message passing in combination with a mechanical
topological graph, outputting a component state and a complete
machine state, and packaging the component state and the complete
machine state into a mining
equipment state prediction set. According to the method,
structured analysis of the twinborn dynamic residual error is realized, and the method is used for accurately positioning an abnormal event and improving the sensitivity and timeliness of
state prediction.
