摘要
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 effectiveness of evacuation signage under emergency,an evacuation route optimization algorithm was developed for intelligent evacuation instructions system based on the factor of evacuee's information perception.The intelligent evacuation direction signage for a specific public place was improved with the consideration of basic principles of safety evacuation,the installation location of intelligent evacuation direction system,the building space structure and typical fire scenarios,the path length,exit width,the factors of evacuee population density and distribution. Simulations were carried out. The results show that the improved intelligent evacuation direction signage can guide evacuees to more reasonable evacuation exits and effectively shorten the evacuation time.
