摘要
基于虚拟现实技术的虚拟应急演练有着广泛的应用,但现有演练系统往往缺少对灾害场景的有效仿真,以及预案支撑下的完整系统框架.针对上述问题,该文首先提出了一种面向应急演练的仿真系统VEDSimu,解决了实体间消息高效传输、大规模仿真模型计算问题;并基于VEDSimu开发预案脚本系统、预案推理机、考核评价以及虚拟现实客户端等其他模块,构建虚拟应急演练系统VEDSys.最后,结合VEDSys在实际企业虚拟消防演练中的应用,验证了系统的可行性、高效性与可扩展性.
Virtual reality-based virtual emergency drill has wide application. But existing drill systems lack accurate environmental simulation and plan support. In this paper, a virtual emergency drill simulation system （VEDSimu） was proposed. It solved the entity message passing problem and large-scale simulation model computing problem. Then, a virtual emergency drill system （VEDSys） was constructed. It implemented plan script system, plan inference engine, evaluation system and virtual reality client based on VEDSimu. Furthermore, VEDSys was proved to be feasible, efficient, and scalable with the application in actual company virtual fire drill.
