摘要/Abstract

摘要： 突发性事故会在短时间内排放大量有毒有害污染物,危害性极大,极其需要对其扩散做出快捷、准确、普适性应对。采用高斯烟团模型来对气体污染扩散进行模拟仿真,并对其进行了轻量化处理,使得其在Web3D的 Three.JS框架得以实现,用户们通过访问网页即可实时访问有毒气体扩散全部可视化过程,可以便捷地估计出有毒气体的污染扩散趋势,还可以进一步分析在不同影响条件下的气体污染扩散对周围环境的影响。借助于本平台,用户还可以对各种有毒气体扩散模型数据进行管理,并自主设置各种有毒气体扩散参数,极大地方便了用户对气体污染扩散平台的操控。

Abstract: The sudden accidents usually emit large quantities of toxic gases and harmful pollutants in a short time. It is very necessary and meaningful to predict and visualize the dispersing trend of those toxic gases over Internet as accurate and fast as possible for people to evacuate safely and immediately. We propose a lightweight simulation for air pollution dispersion based on the Gaussian puff model. With this method, we can visualize the procedure of toxic gas dispersing on a webpage in real-time. we can also estimate the pollution of toxic gas dispersion trend and analyze their further pollution effects on the surrounding environment under different air conditions. We implement our ideas with Three.JS framework in a Web3D manner. With the help of this platform, users can not only manage all kinds of toxic gas dispersion model data, but also set up the data of toxic gas dispersion, which is convenient for pubic to use.

Key words: lightweight, Gaussian puff model, WebGL, process visualization, GIS
