Problems solved by technology

Therefore, existing research ignores that situational communication is a space-time dynamic process, and does not consider the complex space-time interaction process between situation and individuals, which ultimately leads to obvious deficiencies in event situation and individual driving mechanism, crowd evacuation behavior simulation, etc.

Embodiment Construction

[0041] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] The present invention proposes a situation-aware-oriented spatio-temporal dynamic process, revolves around events, individuals, and the spatio-temporal interaction mechanism between individuals in emergencies, simulates crowd evacuation behavior in complex geographical scenes, and provides a reasonable and effective emergency evacuation in emergencies. decision reference.

[0043] The embodiment of the present invention proposes a crowd emergency evacuation simulation method based on the situation and individual spatiotemporal interaction process. Based on the temporal geography theory, events and individual spatiotemporal behaviors are described in a unified time frame. Through reasoning and analysis of spatiotemporal processes, Reveal the spatiotemporal interaction mechanism between emergencies and individuals and in...

Abstract

The invention provides an emergency crowd emergency evacuation simulation method based on a time-space interaction process, and the method comprises the steps: constructing a space-time interaction mechanism between an emergency and an individual and between individuals based on a unified space-time framework; based on time-space interaction mechanism analysis, constructing an individual time-space dynamic evacuation behavior, simulating a population evacuation process driven by an emergency by using a solid force model, and carrying out evacuation evaluation index analysis. According to the scheme, implementation is easy and convenient, practicability is high, the crowd evacuation behavior under the complex geographical scene is simulated, and the simulation result can provide reasonable and effective decision reference for emergency evacuation under emergencies; the problems of low practicability and inconvenience in practical application in related technologies are solved, the user experience can be improved, the great loss of manpower and material resources is avoided, and the method has important market value.

Description

technical field [0001] The invention belongs to the field of crowd emergency evacuation computer simulation simulation, relates to a crowd emergency evacuation simulation method, in particular to a crowd emergency evacuation simulation method based on the interaction process of situation and individual time and space. Background technique [0002] In the event of a major emergency such as a fire or an earthquake in a public gathering place, if there is no emergency evacuation plan, it is likely to cause serious safety hazards and pose a serious threat to the life, health and safety of the crowd. Crowd emergency evacuation simulation can provide reference for the design of emergency evacuation plan in emergencies, and can check and verify the designed emergency plan, which is an important topic to reduce the safety risk of emergencies. [0003] With the rapid development and wide application of various new sensor monitoring technologies and video analysis technologies, the lo...
