Leakage gas diffusion region analysis method, terminal equipment and storage medium

Abstract

The invention relates to a leaked gas diffusion region analysis method, terminal equipment and a storage medium. The method comprises the following steps: S1, calculating leaked gas concentrations corresponding to different coordinates after gas leakage; s2, grouping the coordinates according to the concentration of the leaked gas; s3, for each group of coordinates, extracting coordinates at a boundary position in a formed graph and setting the coordinates as boundary coordinates; s4, calculating the center point of each group of boundary coordinates; s5, for each group of boundary coordinates, sequentially calculating an included angle between a connecting line between each boundary coordinate and the central point and the longitude positive direction, and sorting according to the size of the included angle; and S6, aiming at each group of boundary coordinates, performing line connection on corresponding positions of the boundary coordinates on the map according to the serial numbers, performing end-to-end connection, and taking an area enclosed after line connection as a leakage gas distribution area of each group of corresponding concentration. According to the invention, the leakage gas area is visually displayed, so that fire-fighting or rescue workers can be helped to quickly carry out pollution assessment and carry out rescue.

Description

technical field [0001] The invention relates to the field of environmental safety, in particular to a method for analyzing a leaked gas diffusion area, a terminal device and a storage medium. Background technique [0002] When a harmful gas leak occurs in the chemical industry, the leaked gas will gradually spread to the surrounding area over time. In order to ensure the personal health and safety of the residents in the surrounding area, it is necessary to monitor the concentration of the diffused area. [0003] Many countries have done a lot of research in order to study the diffusion mechanism of dangerous gases and verify the mathematical and physical models. In the 1990s, the leakage and diffusion of toxic substances such as liquid ammonia, LNG, LPG, and hydrogen fluoride were studied, and field experiments were carried out on the leakage and diffusion of toxic substances. However, due to factors such as model size, personal safety, and uncertain factors in the surroun...

Problems solved by technology

However, due to factors such as model size, personal safety, and uncertain factors in the surrounding environment, the scope of application of existing models is greatly limited, so it is difficult to determine the initial conditions for calculation and verify the model.
