Abstract:

In building fire rescue, the existing building internal path is mostly the shortest , which is difficult to realize the indoor path planning for different rescue needs. The paper puts forward an indoor fire rescue path optimization method based on BIM . The fire rescue model is established by BIM Technology, and the three-dimensional indoor road network is constructed in the model to give different attribute weights to different road network nodes. Combined with path generation algorithm and path optimization rules, the safest path and the optimal firefighting path are added on the basis of the shortest path. The fire rescue route is more optional and the fire command is more convenient.
