Abstract

The invention discloses a visualization method for emergency early warning of sudden toxic gas leakage. The method comprises the steps: completing the collection of meteorological wind field data, chemical plant data, road network data and geographic data, and carrying out the preprocessing of the collected data; establishing a streaming database for the wind field data; predicting a poison gas diffusion range after a sudden poison gas leakage accident occurs in the chemical plant through the Gaussian puff model, and calculating evacuation path plans of all citizens in the affected range according to a poison gas diffusion range prediction result; finally, outputting a fusion view of accident surrounding geographical condition visualization, wind field visualization, poison gas diffusion range prediction result visualization and evacuation path planning visualization in real time. According to the method disclosed in the invention, an urban emergency management department can be helpedto make reasonable emergency decisions more efficiently in a specific scene of sudden toxic gas leakage disasters, and life safety threats to citizens are reduced.

Description

technical field

[0001] The invention relates to the technical field of information visualization analysis, in particular to a visualization method for emergency early warning of sudden poison gas leakage. Background technique

[0002] With the rapid development of my country's chemical industry, the number of chemical plants built around cities is increasing day by day. The sudden leakage of toxic and harmful gases caused by accidents in these chemical plants will pose a huge threat to the lives of surrounding citizens. After the outbreak of the poisonous gas leakage accident, before the poisonous gas spreads to the area where the citizens are located, the local emergency management department needs to make reasonable and effective decisions in a short period of time, and evacuate the citizens who may be affected by the highest efficiency under the condition of ensuring the safety of the citizens. Life and health threats to citizens. Whether the decision made by the emergen...
