The invention relates to the technical field of safety engineering, and discloses a gas leakage evacuation control method and system, which are applied to enterprises with toxic gas dangerous sources, and the method comprises the following steps: obtaining a vector map about enterprise geographic information; determining real-time meteorological data; acquiring leakage accident source position information; according to the enterprise geographic information, the real-time meteorological data and the leakage accident source position information, dynamically simulating and displaying the toxic gas leakage diffusion condition, and determining the real-time influence degree on each production device area of the enterprise; and determining a personnel evacuation path corresponding to each production device area in real time according to the parameters. The real-time meteorological data is combined, the real-time influence degree of poisonous gas leakage on each production device area of the enterprise is determined, the vector map of the enterprise is combined, the personnel evacuation path is determined for each production device area, the personnel evacuation path can be dynamically adjusted in real time, and field personnel can be evacuated through the shortest path.

Description

Technical field [0001] The present invention relates to the field of safety engineering, and in particular, to a gas leak evacuation control method and a decision system. Background technique [0002] The emergency evacuation of accidents is a key step in reducing casualties during the emergency rescue process. It is also an emergency response method. Emergency evacuation is to address emergencies and decision-making in the accident, and to evacuate the area, distance, Detailed regulations such as routes, transportation tools, safety set points. [0003] At present, there is a certain study regarding accident emergency evacuation auxiliary decision-making, for example, using Gaussian classic computational model to realize the display and analysis of the accident impact area; use Floyd algorithm (Floyd-Warshall, Freud Algorithm, also known as interposition Law), SPFA algorithm (SHORTEST PATH FASTER Algorithm, Bellman - Ford Algorithm Queue) and Dijkstra Algorithm (Dijkstra's Algor...

AI Technical Summary

Problems solved by technology

[0004] (1) There is a lack of real-time dynamic emergency evacuation auxiliary research and judgment process, which cannot scientifically reflect the dynamic change process of gas leakage accidents, and is not suitable for the toxic gas diffusion process where the diffusion process has a great impact on the personnel of peripheral devices and the diffusion range is constantly changing;

[0005] (2) The evacuation path algorithm and constraint conditions of the diffusion model are simple, which is only applicable to the situation of relatively simple evacuation routes, and does not consider the particularity of toxic gas leakage accidents in petrochemical enterprises
