This invention discloses a digital prediction and reverse causal chain diagnosis method for hydrogen refueling station fires, belonging to the field of fire prediction and diagnosis technology. Based on the environmental parameters and leakage source parameters of the hydrogen refueling station, a multivariate coupled operating condition is designed to simulate a hydrogen refueling station fire and construct a database. Based on the Transformer model, a learnable location encoding mechanism is designed to dynamically fuse spatiotemporal coordinate features, training a fire development prediction model. By fusing temperature sensor data through a spatiotemporally coupled Transformer model, a diffusion generation architecture with residual constraints is constructed, training a fire temperature visualization prediction model. Based on the temperature sensor data and environmental parameters of the hydrogen refueling station, combined with the fire development prediction model and the fire temperature visualization prediction model, digital prediction of hydrogen refueling station fires is achieved. A reverse causal chain diagnosis method based on fault trees and multi-source data is established to achieve second-level root cause diagnosis. This invention is used for more accurate prediction of hydrogen refueling station fires and reverse causal chain diagnosis.
