双层教学楼人员疏散仿真研究

Study of Crowd Evacuation in Two-Story Teaching Building

为了研究多层建筑的人员疏散问题,以双层教学楼为背景,基于事件/委托机制和多智能体技术,提出了人员视觉感知模型,并实现了模型间的通信交流。在考虑环境熟悉程度、生理和心理因子影响的基础上,建立了火灾数学模型和视觉感知模型,分析了出口、楼梯口和楼道火灾3种场景下的人员疏散情况,重点模拟了楼梯疏散中的人员行为准测。实验结果表明,该模型能够比较真实的体现火灾环境下的教学楼人员疏散情况,有助于多层建筑疏散问题的研究。

In order to study the multi-level building evacuation problem, visual perception ana communication exchange of personnel model was achieved based on the Delegate/Event mechanism and Multi-agent technology, moreover, which set in two-story teaching building. Considering about the extent of the familiar environment, physiological and psychological factors, a mathematical model of fire and visual perception model was established, analyzing the personnel evacuation under three fire scenarios exit, stairs and corridor, moreover, focusing on simulation of personnel evacuation behavior in the stairway. The experimental results show that this model can truly reflect the building evacuation in fire environment, which contributes to the study of the multi-level building evacuation.
