Problems solved by technology

[0004] (1) The obedience rate of individuals is not considered. In the path optimization research of individual evacuation, the optimization is often carried out with the goal of global optimum, which may cause the evacuation route of some individuals to be not the optimal path for itself. Therefore, There may be some individuals who do not evacuate according to the optimized path, and these individuals who choose to evacuate independently may affect the entire evacuation plan;
[0005] (2) The group is used as the evacuation object for path assignment, ignoring the specific location of each individual, which may affect the accuracy of the evacuation results;
[0006] (3) The lack of interaction between the command center and the individual, that is, how to quickly communicate the optimized evacuation plan to the individual's hands

Embodiment 1

[0044] refer to figure 1 , the present embodiment provides a location-based crowd evacuation route recommendation method, which specifically includes the following steps:

[0045] S101: Construct a three-dimensional model of an evacuation scene and determine coordinate information of all preset key positions in it.

[0046] It should be noted that the evacuation scene may be a subway station or a shopping mall. The preset key positions can be positions such as escalators, elevators or safety exits.

[0047] S102: Taking the current position of each individual in the evacuation scene as the starting point, the exit of the evacuation scene as the end point, and each preset key position as the intermediate node, the social force model combined with the shortest path is used to optimize the evacuation path of each individual.

[0048] In some embodiments, the current position of each individual in the evacuation scene is acquired using an ultra-wideband-based indoor positioning ...

Embodiment 2

[0086] Such as Figure 7 As shown, the present embodiment provides a location-based crowd evacuation route recommendation system, which includes the following modules:

[0087] Model construction and coordinate positioning module, which is used to construct a three-dimensional model of the evacuation scene and determine the coordinate information of all preset key positions in it;

[0088] The evacuation path optimization module is used to take the current position of each individual in the evacuation scene as the starting point, the exit of the evacuation scene as the end point, and each preset key position as the intermediate node, and use the social force model combined with the shortest path to optimize the evacuation path of each individual. Optimizing evacuation routes;

[0089] An evacuation route recommendation module, which is used to display the optimized individual evacuation route in the three-dimensional model of the evacuation scene, and recommend it to the corr...

Embodiment 3

[0098] This embodiment provides a computer-readable storage medium, on which a computer program is stored, and when the program is executed by a processor, the steps in the method for recommending a location-based crowd evacuation route as described above are implemented.

Abstract

The invention belongs to the field of crowd evacuation path recommendation, and provides a position-based crowd evacuation path recommendation method and system. The method comprises the following steps: constructing a three-dimensional model of an evacuation scene and determining coordinate information of all preset key positions in the three-dimensional model; taking the current position of each individual in the evacuation scene as a starting point, taking the exit of the evacuation scene as a terminal point, taking each preset key position as an intermediate node, and adopting a social force model to combine with the shortest path to optimize the evacuation path of each individual; and displaying the optimized individual evacuation path in the three-dimensional model of the evacuation scene, and recommending the optimized individual evacuation path to the corresponding individual terminal. When the evacuation path optimization is performed on the crowd, the space-time states of the individuals before the current individual sequence are fully considered, so that the space-time conflict of the individuals can be avoided, the time difference between the individuals can be fully utilized, and the evacuation and escape efficiency of the individuals in the public place is improved.

Description

technical field [0001] The invention belongs to the field of crowd evacuation route recommendation, in particular to a position-based crowd evacuation route recommendation method and system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] The recommendation of crowd evacuation routes is of great significance to the response to emergencies in public places. In particular, subway stations are built underground, and the space is highly enclosed. When sudden accidents such as fires and floods occur in subway stations, it is particularly difficult for individuals to evacuate in an emergency, which brings safety hazards to individuals who choose to travel by subway. The following problems generally exist in the optimization of evacuation routes in public places (such as subway stations): [0004] (1) The obedience rate of individuals is not co...
