建筑火灾中智能疏散诱导系统的实验研究*

摘要

为了验证智能疏散诱导系统的有效性，建立“黑屋”实验平台，设定不同的火灾场景，采用CFAST方法，得到火灾到达危险时刻的时间，用多组人群进行多次疏散实验，获得实际的最大安全疏散时间。根据时间判据，分析智能疏散诱导系统与人群疏散行为的相互作用机制。%In order to certify the effectiveness of the intelligent evacuation guiding system, an experimental platform, “black room”, is set up to simulate different fire scenes. It is to obtain the time when the fire is uncontrollable through the method of CFAST; do evacuation experiment for many times with multiple groups of people to obtain the actual maximum safe evacuation time; and analyze the interactive mechanism of the intelligent evacuation guiding system and the crowd evacuation action in accordance with time criterion thereof.
