基于BIM的消防灭火动态路径规划研究

Study on Dynamic Planning of Fire Fighting Path Based on BIM

为服务于城市火灾应急救援工作,针对复杂楼宇消防救援问题,选取集学术交流、办公、授课、实验、图书馆等多重功能于一体的某综合性办公楼作为研究案例,通过解析BIM的IFC标准文件提取空间信息构建动态路径矩阵,综合考虑火源对室内路网的影响、消防设备的空间位置和智能硬件反馈信息,优化Dijkstra算法构建基于Unity3D场景最优三维路径,实现基于消防设备的动态灭火引导路径规划,可以为城市消防救援指挥提供支持,为改进火灾应急救援提供有益的参考.

In order to serve the urban fire emergency rescue work,aiming at the fire rescue problem of complex buildings,a comprehensive office building,which integrates multiple functions such as academic exchange,office,teaching,laboratory,library and so on,is selected as a research case.By analyzing IFC standard files of BIM,the spatial information is extracted to construct a dynamic path matrix,considering the impact of fire source on the indoor road network,the spatial location of fire-fighting equipment and intelligent hardware feedback information,optimizing Dijkstra algorithm to build the optimal 3 D path based on Unity 3 D scene,so as to realize the dynamic fire-fighting guide path planning based on fire-fighting equipment.This research can provide support for urban fire rescue command and provide useful reference for improving fire emergency rescue in China.
