摘　　要：介绍动态标志的工作原理及光源的选择原则,建立动态标志对人群疏散影响的表达式,研究动态标志的控制策略。在"黑屋"实验平台上,借助烟气发生装置混入6%的醋酸模拟烟气环境,用CFAST计算火灾危险来临时间,通过不同特征人群的疏散实验,分析从众度、偏向度对人群疏散行为的作用机制,研究照度、人群密度与疏散时间的关系,得到人群必需疏散时间。结果表明:动态标志能够改变人员选择出口的概率,达到人群均衡疏散的目的。The working principle and the choice principle of dy- namic identity light source was introduced. The mathematical description of dynamic identity effect on the crowd evacuation was built, and the controlling strategy was studied. With the aid of smoke generator with 6% acetic acid to simulate smoke environment, and utilizing CFAST to calculate the fire hazard time, organizing evacuation experiment of various characteristics crowd in ＂black room＂ experimental platform. Analyzed crowd evacuation relationship with conformity degree and bias degree, and studied the correlation intensity of illumination, crowd density and evacuation time, getting crowd necessary e- vacuation time. The results showed that dynamic identity can change the probability of evacuees choosing the path or exports, to achieve the purpose of crowd evacuation equilibrium.
