为改善疏散指示标志在紧急情况下的疏散引导效果,基于逃生者的信息感知等因素,开发智能疏散指示系统的疏散路线优化算法。将安全疏散的基本原则、智能疏散指示系统的设置位置、建筑空间结构及典型火灾场景相结合,综合考虑路径长度、出口宽度、人员密度以及疏散人群分布等因素,针对特定场景,改进智能疏散指示标志。结果表明:改进后的指示标志能指引人员迅速找到疏散路线,有效地缩短疏散时间;将指示标志的控制作用纳入人群分布预测模型,可得到更接近真实情形的疏散人群分布预测模型。
In order to improve the evacuation guidance effect of evacuation indicator in emergency and to develop evacuation route optimization algorithm of evacuation indication system based on factors such as information perception of evacuers. Based on the basic principles of safety evacuation, the location of intelligent evacuation indication system, the building space structure and the typical fire scene, considering the path length, exit width, staff density and evacuation population distribution, Sign. The results show that: the improved indicators can guide people to quickly find evacuation routes and effectively shorten the evacuation time; and incorporate the control of indicators into the population distribution forecasting model to obtain the evacuation crowd distribution prediction model that is closer to the real situation.
