【摘要】 地铁是城市交通中的重要运输工具,大城市生活节奏加快,地铁的乘坐人群与日俱增。同时,地铁突发灾害的可能性和危险性也随着使用群体的增加而迅速增加。为了减少事故带来的损失,需要做好提前的推演和预先的防范,有效的推演是应急救援中的前置工作,也将为预防措施的布局提供实践依据。虚拟现实技术为事故推演提供了虚拟化、自动化及智能化的实现方式。利用动画设计软件在计算机上搭建出符合现实的地铁模型,利用综合开发工具实现无缝人机交互系统的设计,以此模拟人群在地铁火灾中的逃生情况。结果表明:虚拟现实技术可以投入灾害推演的模拟当中,对逃生系统设计以及预防措施制定具有一定参考意义,同时能提高应急决策的效率,降低经济成本。更多还原

【Abstract】 Subway is an important transportation tool in urban transportation. The rhythm of life in big cities is accelerating, and the number of people taking subway is increasing day by day. At the same time, the possibility and danger of sudden subway disasters increase rapidly with the increasing in the number of users. In order to reduce the losses caused by accidents, advance drills and precautions need to be done. Effective drills are the preparatory work in emergency rescue and provide practical basis for the layout of preventive measures. Virtual reality technology provides a virtual, automated, and intelligent implementation of accident drills. In order to simulate the reality of the crowd in the subway fire disaster, using animation design software to build the subway model on the computer, using integrated development tools to achieve seamless human-computer interaction system design. The results show that virtual reality technology can be put into the simulation of disaster precautions drills, which has certain reference significance for the design of the escape system and the establishment of preventive measures. At the same time, it improves the efficiency of emergency decision-making and reduces economic costs.更多还原
