摘要
室内建筑污染区域会受到空气对流作用的影响,导致污染物的扩散方向和扩散速度都发生无序变化,污染区域呈散乱分布。传统的室内建筑污染扩散程度计算是基于污染物均匀分布的区域进行计算的,忽略了空气对流作用对污染区域均匀分布的影响,导致无法准确计算室内建筑污染扩散面积。为了避免传统方法的弊端,提出一种基于移动区域优化算法的室内建筑污染扩散面积的计算方法。利用对室内污染物区域边缘的空间位置提取数据建立模型,利用模型计算出污染物扩散过程中的污染区域面积,对扩散过程中的污染面积误差进行补偿处理,实现了对室内建筑污染扩散面积的准确计算。仿真实验表明,利用该算法能够对室内建筑污染扩散面积进行准确计算,从而准确判断出室内污染扩散的程度。
The indoor building pollution area will be affected by the air convection, lead to the spread of pollutants and disordered diffusion speed, pollution is scattered distribution. Traditional indoor building pollution diffusion calculation is based on the uniform distribution of pollutants calculated area, ignoring the air convection influence on pollution area were distributed evenly, lead to can not accurately calculate the indoor floor pollution diffusion area. In order to avoid the disadvantages of traditional methods, this paper puts forward a mobile area optimization algorithm based on the calculation method of indoor building pollution diffusion area. Area on the edge of the space location of indoor pollutants is utilized to extract the data model, using the model to calculate the pollution in the process of pollutant diffusion area, to compensate the pollution area of error in the process of diffusion, realize the accurate calculation of indoor building pollution diffusion area. Simulation results show that the algorithm can to accurately calculate the interior construction and pollution to calculate area, so as to accurately determine the degree of indoor pollution diffusion.
