基于GIS的应急逃生模拟系统的研究与实现

摘要

A pharmaceutical factory was selected as an example to develop Emergency escape Simulator system .Through Three-di-mension modeling of the factory and factory road network data ,Set up of topological relations of spatial data,Implement emergency e-vacuation path analysis functions.Use three dimensional virtual reality engine to achieve visualization and simulate emergency escape. This research through the establishment of simulation system, Played a decision-making role in the "Peacetime"emergency drills and"wartime"emergency rescue.Provides a scientific basis for development of aid programmers.%本研究以某化学制药厂为例，通过对整个厂区进行三维建模，以及建立厂区路网数据，建立起空间数据的拓扑关系，实现厂区各位置之间的路经计算分析，从而便于生成应急疏散路径。运用三维虚拟现实引擎进行可视化，并进行模拟逃生。本研究通过建立模拟系统，对“平时”的应急演练以及“战时”的应急救援起到了决策支持作用，为决策者制订救援方案提供了科学依据。
