摘要
为了火灾发生时准确监测火灾烟雾颗粒物扩散路径,提出高层建筑火灾烟雾颗粒物扩散路径监测方法。利用以HOG特征为基础的多特征组合模型,对高层建筑火灾烟雾颗粒物进行特征提取。在获取高层建筑火灾烟雾颗粒物特征的基础上,通过PyroSim软件组建高层建筑物理模型,获取火源位置处烟气流动的特点以及规律,实现高层建筑火灾烟雾颗粒物扩散路径监测。通过具体的仿真测试可知,所提方法能够快速、准确获取火灾烟雾颗粒物扩散的具体路径。
In order to accurately monitor the diffusion path of fire smoke particles during the fire,a method for monitoring the diffusion path of smoke particles in high-rise buildings is proposed.Feature extraction of smoke particles from elevated building fires is carried out using a multi-feature combination model based on HOG features.On the basis of obtaining the characteristics of smoke particles in high-rise buildings,the physical model of high-rise buildings was built by PyroSim software to obtain the characteristics and laws of smoke flow at the fire source location,and to realize the monitoring of smoke particle diffusion paths in high-rise buildings.Through specific simulation tests,the proposed method can quickly and accurately obtain the specific path of fire smoke particle diffusion.
