[0007] However, in these simulation models, the information mastered by people and the influence of people's subjective will on the evacuation process are ignored, and individuals are set to have perfect information and complete rationality, which deviates greatly from the reality

Embodiment Construction

[0023] (1) Application of cellular automata and multi-agent technology

[0024] (1) Cellular white motor

[0025] In the traditional cellular automata theory, multiple agents can be accommodated in a grid. When the number of agents exceeds a certain value, an agent is selected according to certain rules and moves randomly to the adjacent grid. When the agent is a person, this rule is often the priority, that is, the person with the worst mental state to leave. The premise is that the environment in which the cellular automaton is applied has characteristics—the agent can reach every place in the environment regardless of obstacles.

[0026] But the environment to be studied by the present invention must have internal obstacles, and the places with obstacles are just inaccessible. In addition, the collapse of buildings, fire or poisonous gas attacks will definitely affect the surrounding environment, and people's health and vision are not fixed. In this case, having ...

Abstract

The invention relates to a pedestrian evacuation simulation method based on an extended BDI (base diffusion isolation) model. The method is based on the extended BDI model, a cellular automaton and a multi-agent technology are adopted, and personnel evacuation in public places in emergency (such as a fire disaster) is simulated according to plane layout of the actual building. According to the method, influence of psychological states of personnel on evacuation is fully considered in a pedestrian simulation process, certain support is given to the spirit factor by virtue of an extended BDI system structure, and the method is more consistent with the reality when being applied to pedestrian simulation with incomplete environmental information. The method disclosed by the invention has a wide application prospect in personnel safety and rapid evacuation simulation research, can test a design scheme or a response scheme and is an economically feasible pedestrian evacuation simulation method.

Description

technical field [0001] The invention relates to crowd simulation in computer graphics, in particular to a simulation model of personnel evacuation in a public place established based on an extended BDI model in an emergency (such as a fire) and its system realization. Background technique [0002] With the development of social economy and cities, large-scale buildings, such as skyscrapers, stadiums, stations, docks and airports, have emerged in large numbers. In these places, there are usually a large number of people coming in and out or staying. How to safely and quickly evacuate a large number of people in a building is not only a problem that must be carefully considered and studied when designing a building, but also an important research topic for emergency response plans for existing buildings. In this aspect of research, it is more economical and feasible to test the design scheme or response plan through computer simulation. [0003] Once an emergency occurs, whe...
