三维楼宇应急疏散仿真系统研究

Research on 3D Building Emergency Evacuation Simulation System

应急疏散模拟是有效避免人员伤亡的重要措施。针对楼宇行人安全疏散问题,提出了一种三维楼宇应急疏散仿真系统。该系统可根据智能体在紧急环境中遇到的不同情况,设置并可视化其行为。通过三维模型设计与可视化仿真技术进行场景搭建;通过基本功能模块,应急模拟模块、数据统计模块对天津测绘院大楼进行实验,结果表明:该系统能有效模拟楼宇内人员疏散情况,可用于灾害发生时的应急疏散指导和灾情疏散模拟演练。

Emergency evacuation simulation is deemed as a significant measure to effectively avoid casualties.For the safety evacuation of pedestrians in buildings,a three-dimensional building emergency evacuation simulation system is proposed.The behavior of agent can be set and visualized according to different situations encountered by the agent in an emergency environment.The scene was built through three-dimensional model design and visual simulation technology;through the basic function module,emergency simulation module,and data statistics module,the experiment of the Tianjin Surveying and Mapping Institute building was conducted.The results show that the system can effectively simulate the evacuation of people in the building,and can be used for emergency evacuation guidance and disaster evacuation simulation exercise in the event of a disaster.
