基于VR的隧道火灾疏散指挥训练系统

VR-based tunnel fire evacuation commander training system

为减少隧道火灾造成的人员伤亡,基于虚拟现实（VR）技术,开发火灾疏散指挥人员的训练系统。该系统通过VR设备采集指挥者的动作、声音等指令,动态模拟疏散人群对指令的响应情况;将人群的响应行为和其自疏散行为相结合,再置于火场环境中,综合模拟疏散指挥过程;对指挥效果进行数值化评估。应用该系统在上海市大连路隧道模型进行模拟试验。试验结果显示：挽救人数随训练次数呈递增趋势,且在典型情境下,受训人员的指挥结果均能达到应急预案的要求,证明该系统能够通过模拟训练来优化疏散指挥人员的指挥行为。

In order to reduce the casualties caused by tunnel fires,a VR technology based training system for fire evacuation commanders was developed. The system collects commands and voices of commanders through VR devices to dynamically simulate the response of evacuees. By combining the response behavior with self-evacuation behavior of evacuees,and placing it in the fire environment,the evacuation command process was simulated comprehensively,and the command effect was evaluated numerically. The system was simulated in the Dalian Road tunnel model in Shanghai. The results show that the number of rescuers is increasing along with training times,and simulation results of trainees under typical situations can meet the requirements of emergency plans,and that the system can optimize the behavior of commanders through training.
