Example Embodiment

[0056] The present invention will be further described below with reference to the drawings and embodiments.

[0057] This embodiment provides an indoor evacuation simulation method based on a mixed space, such as figure 1 As shown, including the following steps.

[0058] Step 1. Calculate the discrete static gravitational field of the evacuation site.

[0059] Step 2. Calculate the dynamic gravitational field of a single pedestrian according to the pedestrian's escape strategy.

[0060] Step 3. Calculate candidate movable positions based on the dynamic gravitational field of each pedestrian.

[0061] Step 4. Traverse each pedestrian and repeat steps 2 and 3 until all pedestrians have been evacuated.

[0062] Further, when the evacuation site is a regular rectangular site and there are no obstacles in the site, the evacuation site is rasterized, and the calculation formula of the discrete static gravitational field of the evacuation site is:

[0063]

[0064] In the formula, S represents...

Abstract

The invention relates to an indoor personnel evacuation simulation method, in particular to an indoor personnel evacuation simulation method based on a hybrid space. The method comprises the following steps of 1, calculating a discrete static gravitational field of an evacuation site; 2, according to an escape strategy of pedestrians, calculating a dynamic gravitational field of a single pedestrian; 3, according to a dynamic gravitational field of each pedestrian, calculating candidate movableness positions; 4, traversing each pedestrian, and repeatedly carrying out step 2 and step 3 until all the pedestrians are evacuated. The indoor personnel evacuation simulation method based on the hybrid space comprehensively uses characteristics of rule simplicity and high computational efficiency which are based on a discrete space model and the characteristic of high simulation degree based on a continuous space model, and is suitable for evacuation simulation of personnel in large indoor complicated sites such as a station, a shopping mall and a gymnasium.

Description

technical field [0001] The invention relates to an indoor personnel evacuation simulation method, in particular to an indoor personnel evacuation simulation method based on a mixed space. Background technique [0002] With the continuous development of social economy, various crowded places such as stations, shopping malls, and gymnasiums are constantly increasing. In case of emergencies such as fires and terrorist attacks, if the evacuation of these indoor public places is not good, it is very easy to cause casualties. The current research on evacuation in indoor public places can be divided into two categories: real evacuation drills and evacuation modeling. Compared with real evacuation drills, personnel evacuation modeling has the advantages of low cost and easy implementation. For evacuation modeling, many models and algorithms have emerged, such as social force model, cellular automaton model, field model, discrete choice model, ant colony algorithm, particle swarm o...
