Fire evacuation planning method and system based on digital twinborn technology

The invention relates to a fire evacuation planning method and system based on a digital twinning technology, and belongs to the technical field of fire evacuation, and the method comprises the following steps: building a building digital twinning model, and inputting the position information of each sensor in a building into the building digital twinning model; acquiring a current combustion range and a combustion range expansion speed, and simulating a combustion spreading trend in the building digital twin model; acquiring a smoke drifting direction and a smoke drifting speed, and simulating a smoke drifting trend in the building digital twin model; judging the danger level of each safety channel in each time period; according to the method and the system, the escape condition of the personnel is simulated in the building digital twin model, evacuation planning and guidance are performed according to the simulation result, the escape condition of the personnel is simulated in the building digital twin mode
