Embodiment Construction

[0042] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings:

[0043] figure 1 Flow chart of emergency evacuation route simulation calculation. The terminal program generates a preset weighted undirected graph based on the preset key points of escape in the building and the weights between key points. When using the program, the user sets the escape point, the location of the fire point, and the basic situation of the fire point (if the basic situation is unknown, the default value will be used instead), the program calculates according to the settings and the method of fire and smoke diffusion, and evaluates the key points of escape. The escape key points that cannot be passed will be removed from the escape key points; according to the situation of the fire point, the weight of escape difficulty between each escape key point will be dynamically adjusted through calculation methods. Finally, Dijkstra's algorith...

Abstract

The invention relates to a method for optimally generating and simulating a fire protection escape route in a building. The method comprises the steps of: simulating and pre-generating an internal passage of the building through a simulation platform, and setting escape weights between escape key points and escape key points for an escape passage; simulating the setting of fire ignition points andfire situations after a fire; performing dynamic simulation on the escape passage according to the fire propagation situation; and generating an optimal escape route according to the existing fire dynamic simulation situations, and simulating and displaying the optimal escape route through the simulation platform. Compared with the prior art, the method provided by the invention has the advantages of being able to perform calculation, evaluation and simulation from a pre-generated path in software according to the existing fire situations to provide fast and feasible information for the selection of the fire protection escape route, so that the efficiency of fire rescue in route selection and the escape rescue capability are well improved.

Description

technical field [0001] The invention relates to the field of artificial intelligence, in particular to an intelligent generation and simulation method of a fire escape route in a building. [0002] technical background [0003] With the advancement of urbanization, the existing urban buildings are getting higher and higher, the internal structure is more and more complex, and the population is more and more dense. As the biggest indoor disaster, fire has caused huge economic losses and life hazards to people. In the event of a fire, the choice of the escape route of the building's internal personnel and the rescue route of the external firefighters is the key to reducing the hazard. [0004] At present, the research on the algorithm of fire escape route at home and abroad mainly includes: the establishment of the fire evacuation model needs to comprehensively consider the complex situation of the scene environment, the relationship between space and people, and fully conside...
