摘　　要：室内应急疏散信息对于室内发生紧急情况时的应急处置以及人员逃生非常重要。针对目前室内应急疏散信息存在现势性差、表达方式简单、发布范围小、发布不及时以及不易被关注等问题,设计并开发了一种基于WebGL网络三维可视化技术的轻量化室内应急疏散信息发布系统。该系统以建筑物室内三维模型、室内路径网络为数据源,采用一种多出口室内应急疏散路径规划算法进行逃生路径规划和疏散分区,基于WebGL来搭建轻量化信息发布平台。实验结果表明,该系统能够高效生动地发布室内应急疏散信息,且具有良好的跨平台性,大大提升了人们访问应急疏散信息的便捷性和对安全疏散信息的理解深度。Indoor emergency evacuation information is very important for emergency treatment and personnel escape in case of emergency in the room.Aiming at the problems of the current indoor emergency evacuation information,such as poor current situation,simple expression,small release scope,untimely release and not easy to be concerned,a lightweight method of publishing indoor emergency evacuation information based on WebGL network 3D visualization technology is proposed and implemented.The indoor 3D model of the building and the indoor path network is used as the data source.The algorithm for route planning applied in multi-exit indoor emergency evacuation is used for the escape route planning and evacuation partitioning,and the lightweight information publishing system is built by WebGL technology.The experiment results show that the system not only can effectively release indoor emergency evacuation information,but also has good cross-platform characteristics,which greatly improves the convenience of people accessing emergency evacuation information and the understanding depth of safe evacuation information.
