The invention relates to an indoor fire-fighting design method based on a BIM technology and a passive RFID, and the method employs the professional knowledge of building fire-fighting simulation, andautomatically generates a fire-fighting simulation input file based on the related building information contained in BIM data. Therefore, adverse interference of human factors on the simulation process can be eliminated, the simulation precision is improved, and the cost of using the simulation technology in the design stage is reduced.
