摘　　要：智慧型灭火技术对于确保高楼安全至关重要。提出了一种新的多层建筑火灾应急系统。该系统利用数字孪生模块来获取建筑物的几何尺寸和位置信息,此外还可以监测室内烟雾浓度和温度。如果发生火灾,该系统可以立即向消防部门报告,并且可以根据情况动态调整逃生时间和路径。运用了Revit和PyroSim以及Pathfinder软件模拟多层建筑火灾发生的情况,对烟气浓度和扩散速率进行了模拟分析,以此合理安排人员逃生路径。结果表明:研究不仅可以提升多层建筑灭火的效率,还可以确保能够在消防人员抵达火场之前根据系统提供的信息制定出有效的灭火计划,从而更加精确地预测可能发生的情况,以此保障生命财产安全。Intelligent fire-fighting technology is essential to ensure the safety of high-rise buildings.This paper presents a new fire emergency system for multi-story buildings.It uses digital twin modules to obtain geometric dimensions and location informa-tion of buildings.In addition,the system can also monitor indoor smoke concentration and temperature.If a fire breaks out,the system can immediately report to the fire department,and the escape time and path can be dynamically adjusted according to the situation.This study has demonstrated that Revit,PyroSim,and Pathfinder software can be employed to simulate fire in multi-story buildings,with smoke concentration and diffusion rate being simulated and analyzed to rationalize the escape route of personnel.The results demonstrate that this research can not only enhance the efficacy of firefighting in multi-story structures but also ensure that firefighters can formulate effective firefighting plans according to the information provided by the system before arriving at the fire site,to predict possible situations more accurately,to protect people’s life and property safety.
