Problems solved by technology

In addition, high-rise complex buildings often have several basements with water, electricity, gas and other pipelines, which increase the complexity and difficulty of emergency rescue and evacuation
Therefore, an important function of the emergency response system is the spatial support capability, but the existing emergency response methods are usually based on the two-dimensional space environment, lacking a navigable three-dimensional data model, and unable to realize the network analysis of the three-dimensional space well, delaying emergency rescue and evacuation time

Embodiment 1

[0107] The present invention will be further described by following examples:

[0108] (1) 3D visualization of buildings

[0109] First, use 3DMAX software (computer configuration: Intel Core2 Quad Q8200 (2.33GHz), 2.0G RAM, NVIDIA GeForce 240GT, 512MB video Memory) to carry out 3D scene modeling with real building data. The building to be studied includes doors, stairs, Corridors, rooms, halls and windows, etc. The character models used are rendered and animated using the md2 file format (a key-frame animation) widely used in Quake2.

[0110] (2) EHI-NRM application analysis

[0111] After importing the 3DS building model, generate the EHI-NRM of the building. In the following, the node attribute query, node path query and path calculation efficiency analysis are performed on EHI-NRM.

[0112] 1) Node attribute query

[0113] Use the mouse to select the corresponding node in the 3D visualization module, or enter the node number in the attribute query bar to query the att...

Abstract

The invention relates to an indoor emergency evacuation simulation method for a complex building. According to the method disclosed by the invention, a three-dimensional extended hierarchical node relation model (EHI-NRM) of an internal space unit of the complex building is automatically generated, and the update of a dynamic path of a large-scale complex building is supported; an improved cellular automaton model (ICA) can better simulate jam, avoidance, mass-following and other phenomena of a large-scale crowd during the evacuation process; and an optimal evacuation path is searched in real time in the macro-level through an EHI-NRM dynamic path-finding method, and the ICA is applied in the local level for simulating the behavior characteristics of the crowd. According to the method disclosed by the invention, the evacuation simulation of the large-scale crowd in the large-scale complex building is supported, and the method has important application values for ensuring the safety of staff in the building and improving the decision-making capacity of an emergency rescue department.

Description

1. Technical field [0001] The invention relates to a method for simulating emergency evacuation indoors of a complex building, and belongs to the technical field of space information. 2. Background technology [0002] At present, more and more high-rise complex buildings are emerging in cities. They are generally located in downtown or commercial areas, and the surrounding traffic network and internal structure are extremely complicated. When emergencies (fires, terrorist attacks, etc.) The complex internal structure and the limited entrance and exit on the ground floor will seriously hinder the evacuation and rescue work of personnel, especially when the main structure of the building is damaged, it may cause a large number of casualties. [0003] In order to react quickly to emergencies in a building space, it is necessary to know which rooms and floors are affected, the current occupancy pattern and which routes within the building can safely reach the exits. In addition...
