Abstract

Abstract: Large-scale fire simulation requires a huge amount of calculation and excellent rendering capabilities, which poses a challenge to the realization of a real-time online fire simulation system on the Web. A lightweight Web-based real-time simulation technology framework for subway station fire is proposed. Based on the simplification of calculation formulas in the field of fire safety and the analysis of the impact of smoke prevention facilities in subway stations, a two-stage smoke diffusion model based on smoke bay is proposed to achieve the smoke diffusion trend calculation; a Web-side multi-granularity particle emitter framework at the smoke bay level is proposed to complete the rendering of flames and smoke shapes, and to realize the real-time calculation and visualization process based on the Web. The experimental verification shows that the simulation results of the method in this paper are similar to the simulation results of the professional fire simulation software. And the method in this paper can simulate the fire online in real time by opening the Web page, which has a significant advantage in convenience.
