Problems solved by technology

[0004] The crowd emergency evacuation methods in the prior art are only modeled for a single building indoor environment or outdoor environment, lacking an indoor-outdoor integrated evacuation scheme, and failing to effectively take into account the evacuation behavior characteristics of the crowd in different indoor and outdoor emergency scenarios. As a result, the existing technical solutions have the problem of "incompatibility" between indoor evacuation and outdoor evacuation

Abstract

The invention relates to a crowd emergency evacuation method and system, a terminal and a storage medium. The method comprises the steps of performing indoor and outdoor geometric information registration on an indoor BIM scene data model and an outdoor GIS scene data model, and constructing an indoor and outdoor integrated emergency evacuation grid model; acquiring an evacuation drilling image of an indoor and outdoor scene, mining microscopic evacuation behavior characteristics of evacuated crowds from the evacuation drilling image, and establishing a static geometric attribute-macroscopic state-microscopic evacuation behavior characteristic relation library of the indoor and outdoor scene according to the microscopic evacuation behavior characteristics; constructing an indoor and outdoor integrated emergency evacuation optimization model based on the indoor and outdoor integrated emergency evacuation grid model and the static geometric attribute-macroscopic state-microscopic evacuation behavior characteristic relation library; and solving the indoor and outdoor integrated emergency evacuation model by using an optimization solution algorithm to obtain an optimal dynamic evacuation strategy. The problem that indoor and outdoor evacuation models are incompatible is solved, and the evacuation efficiency can be greatly improved.

Description

technical field [0001] The application belongs to the technical field of urban public safety, and in particular relates to a crowd emergency evacuation method, system, terminal and storage medium. Background technique [0002] Frequent major sudden natural disasters and man-made accidents have caused huge losses to people's lives and property. The first task after a disaster accident is to evacuate the people in the dangerous area as soon as possible. The purpose of crowd emergency evacuation is to evacuate the people at the disaster site to a safe area in the safest and most effective way. It is the most direct and effective way to reduce casualties, and it is also an important part of the response to major disasters. [0003] Major sudden disaster accidents have the characteristics of a wide range of influence, complex emergency scenarios, and many evacuated people. The interior and exterior of buildings are dangerous areas. Run long distances. The suddenness and danger...
