High-rise building emergency evacuation method and system based on digital twinning and electronic equipment

Abstract

The invention relates to a high-rise building emergency evacuation method and system based on digital twinning and electronic equipment. The method comprises the following steps: establishing a digital world twinning with a physical world; analyzing historical personnel evacuation data through the digital world, and predicting personnel space-time distribution data of a physical world according toan analysis result; performing evacuation simulation according to the personnel space-time distribution prediction data, and constructing an evacuation plan evaluation model according to an evacuation simulation result; enabling the evacuation plan evaluation model to generate at least two evacuation plans according to the personnel space-time distribution prediction data, evaluate the at least two evacuation plans, and select an optimal evacuation plan; and establishing virtual-real fusion and dynamic interaction between the physical world and the digital world by adopting Socket, and performing personnel evacuation on the physical world by adopting the optimal evacuation plan. Through a virtual-real interaction mode and collaborative evolution, the problems of emergencies, instability,nonlinearity and uncertainty in the physical world are solved.

Description

technical field [0001] The application belongs to the technical field of urban public safety, and in particular relates to a method, system and electronic equipment for emergency evacuation of high-rise buildings based on digital twins. Background technique [0002] With the acceleration of the urbanization process, there are more and more high-rise buildings in our country. In recent years, domestic high-rise building fires also emerge in an endless stream, and there is a trend of intensification. According to data from the Fire Department of the Ministry of Public Security, there have been 31,000 high-rise building fires across the country in the past ten years, with 474 deaths and direct economic losses as high as 1.56 billion yuan, and indirect losses are even more difficult to count. Due to the complex structure of high-rise buildings, there are characteristics such as rapid fire spread, difficult rescue, and difficult evacuation, which often cause heavy casualties and...

AI Technical Summary

Problems solved by technology

Due to the fact that there are many unpredictable factors in the real fire scene and there is a certain deviation from the simulation environment, the "pre-model" cannot cope with dynamic environmental changes, and the effect of guiding crowd evacuation is limited, and it is impossible to achieve dynamic evacuation induction.
