The application belongs to the technical field of intelligent management of ancient buildings, and provides an ancient building wood component diagnosis and prevention intelligent management method combined with digital twinning, comprising: processing the main diagnosis surface image of the wood component by using a damage diagnosis model to obtain damage state recognition results; integrating the static attribute data of the wood component, and environment exposure data, damage state recognition results and maintenance data to obtain a structured digital twinning archive; obtaining the feature vector of the wood component at each historical time point based on the structured digital twinning archive, and stacking them in time sequence into a three-dimensional feature tensor; inputting the three-dimensional feature tensor into a multi-task time series prediction model to obtain the future damage prediction result of the wood component and the damage influence weight of the historical time point; calculating the SHAP value of the index; generating damage cause description; matching the damage cause description with a decision rule library to obtain the maintenance decision instruction of the wood component and sending it. The accuracy and forward-looking nature of the future damage prediction result of the wood component are improved, and a decision closed loop is formed.
