Evacuation area calculation method and device, electronic equipment and storage medium

Abstract

The invention provides an evacuation area calculation method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining leakage source information and the current meteorological data of a leakage position; processing the leakage source information and the current meteorological data according to a preset diffusion model, and generating leakage object concentration distribution at each time point in a preset time period; rendering the leakage object concentration distribution at each time point in a geographic information system corresponding to the leakage position, and generating a total leakage range area of different levels of responses in a preset time period; and generating evacuation areas of different levels according to the total leakage range areas of the responses of different levels. Therefore, the problem that in the prior art, evacuation area calculation is not accurate enough is solved, the evacuation areas of different levels aregenerated by analyzing the leakage object concentration distribution at each time point in the preset time period according to the leakage source information and the current meteorological data, andthe evacuation area calculation accuracy is improved.

Description

technical field [0001] The present application relates to the field of security technology, and in particular to a method, device, electronic equipment and storage medium for calculating an evacuation area. Background technique [0002] Usually, after a toxic chemical accident occurs, the toxic gas can spread to hundreds of meters or thousands of meters within a few minutes or tens of minutes, and the harm range can reach tens to thousands of square meters, causing poisoning of unprotected personnel. Therefore, in the rescue of toxic chemical accidents, the first task is to determine the safe distance, establish a safe area, and use this as the basis for evacuation and emergency response. [0003] Therefore, it is necessary to reasonably divide the safety area so that the safety area can not only ensure the personal safety of the surrounding people and rescuers, but also meet the actual needs of on-site rescue. Contents of the invention [0004] This application aims to s...

Problems solved by technology

[0005] For this reason, this application proposes a method for calculating the evacuation area, which solves the problem of inaccurate calculation of the evacuation area in the prior art, and analyzes the leakage at each time point within the preset time period according to the leakage source information and current meteorological data. Concentration distribution, and based on the distribution of leaked substance concentration at each time point, the total leakage area of ​​different levels of response is obtained, and finally different levels of evacuation areas are generated according to the total leakage area of ​​different levels of response to improve the accuracy of evacuation area calculation
