Building Fire Information Simulation Based on BIM Technology

In this paper, the building information modelling (BIM) of a large theatre building is established based on the drawings, and the overall design is carried out according to the actual structure of the building, relevant industry norms and fire protection system requirements, including identification, control and evacuation modules. Based on this model, the fire dynamics simulator (FDS) tool is used to conduct a numerical simulation of fire, and the characteristics of different fires in different regions are studied by laying fire detectors, and the physical characteristics of each stage of fire development are recorded, which provides support for the research of multi-sensor data fusion.
