Abstract

The invention provides a toxic gas leakage accident crowd evacuation behavior dynamic prediction simulation device and a working method thereof and belongs to the environmental safety field. Accordingto the device and working method thereof of the invention, qualitative and quantitative relationships between factors, such as toxic gas leakage accident scenarios, diffusion conditions, and individual characteristics of people, and line selection of the people, are determined on the basis of the crowd evacuation dynamics and cellular automata theory, and cellular local movement rules are established; a dynamic expression of evacuation speed that changes with the amount of inhaled toxic gas is established according to critical states and critical conditions for a toxic substance harm model todetect out people poisoning and fatal accidents; a cellular automata theory-based people dynamic evacuation model is established; and the model is used to form a device which simulates the safety evacuation of people in a toxic gas leakage accident in a visualized manner, so that functions such as simultaneous simulation and simultaneous display of toxic gas diffusion and the evacuation behaviorof the people are completed, and therefore, persons responsible for evacuation can be better assisted to make decisions, or the public can be better assisted to master correct escape skills in the case of toxic gas leakage accidents.

Description

technical field [0001] The invention relates to the field of environmental safety, in particular to a simulation device for dynamic prediction of crowd evacuation behavior under poisonous gas leakage accidents. Background technique [0002] With the prevalence of industrial development, natural disasters, accident disasters and terrorism, the occurrence of sudden poison gas leakage accidents is gradually increasing. In the process of production, storage, transportation and use of toxic and harmful chemicals, once a toxic gas leakage accident occurs, the dangerous substance is easily volatile and diffused into the air. Surrounding residents are extremely likely to cause casualties and poisoning accidents of varying degrees, and at the same time, cause environmental damage. Toxic gas leakage has the characteristics of fast speed, large affected area, and large number of evacuated people. When a major poisonous gas leakage accident occurs, the personnel in the dangerous area ...
