基于烟尘风险评估模型的多角色模拟消防演练系统

Multithreaded Synchronous Simulated Fire Drill System Based on Smoke Risk Evaluation Model

基于虚拟现实和服务端引擎技术研发多角色模拟消防演练系统.该系统分为客户端和服务端,客户端基于VIZARD软件设计实现模拟演练系统所需的虚拟场景,结合KBENGINE框架设计服务端,实现多角色同步登录,学员可不受时空限制进行多角色联合模拟演练.为了更逼真地模拟火灾烟尘环境,让学员身临其境,采用火灾动力学数据和三维渲染技术开发真实、准确的火灾烟尘环境.引入烟尘风险评估模型评估不同疏散路径的安全性,以便学员识别最安全的逃生路径.

A multi-threaded synchronous simulation fire drill system was developed on the basis of virtual reality （VR） and server engine technology. The system includes the client and the server. In theclient, Realization of the virtual scenes needed to the simulated fire drill system based on the VIZARDsoftware, which pemlits the trainees to experience a real and safe virtual fire scene. The KBENGINE framework is used to design the server for the puqoose of multi-thread synchronous log in, the traineescan joint simulation training without space and time restrictions. To achieve efctive virtual exercise,fire dynamics data and three-dimensional rendering technology has been especially designed to build arealistic and precise smoke environment. The smoke risk evaluation model was introduced to evaluatethe safety of different evacuation routes so that trainees could identify the safest route to escape.
