Problems solved by technology

This public patent document is aimed at counting the number of people with entrances and exits, and requires the entering and exiting personnel to pass through the pressure array sensor one by one, which obviously cannot meet the requirements for counting the number of people when a large number of people flow into a local area.
Therefore, the layout of the existing people flow monitoring system is not comprehensive enough, the accuracy of the monitoring data obtained is not high, the authenticity and effectiveness are still lacking, and the practicability is insufficient

Embodiment 1

[0038] Such as figure 1 As shown, Embodiment 1 of the present invention provides an emergency early warning method for public area congestion and stampede events, and the early warning method includes the following steps:

[0039] S1. The monitoring terminal takes pictures or video information of people flow in public areas in real time and sends them to the monitoring center of the police station. The pictures or video information include the shooting time. Collecting pictures or video information of people flow in public areas includes the following steps:

[0040] S1-1: Collection of people flow information at entrances and exits of public areas or evacuation passages: laser cameras installed in entrances and exits of public areas or evacuation passages take real-time pictures or video information of people flow at entrances and exits of public areas or evacuation passages;

[0041] S1-2: Collection of people flow information in public areas: Multiple high-definition camera...

Embodiment 2

[0053] Embodiment 2 of the present invention provides an emergency early warning method for public area congestion and stampede events. On the basis of Embodiment 1, the embodiment 2 further defines the specific method of step S2, which improves the real-time operability of the method.

[0054] It should be noted that step S2 also includes the monitoring center of the police station collecting, storing and reporting the pictures or video information taken by the monitoring center. The specific method includes the following steps:

[0055] ①Data collection: the algorithm server collects the pictures or video information sent by the laser camera and the high-definition camera in the public area in real time, and stores the collected pictures or video information; ②Users access the algorithm through a browser When using the server, the user sets the reporting frequency, and when the reporting frequency is reached, the algorithm server sends the converted and processed people flow ...

Embodiment 3

[0061] Embodiment 3 of the present invention provides an emergency early warning method for crowding and stampede events in public areas. On the basis of Embodiment 1, this embodiment 3 further defines step S3, which improves the versatility and practicability of the method.

[0062] It should be further explained that, in order to realize the alarm estimation of the flow of people in the public area, the technical solution defines that the sub-bureau management server described in step S3 also includes an early warning analysis method, and the specific method includes the following steps:

[0063] ①The branch management server monitors the accurate number of people in the public area in the adjacent time period in real time, and calculates and processes the increase in the number of people to obtain the increase in number; Calculate the time required to reach the alarm threshold and display the time on the user's browsing page based on the number of people growth value obtaine...

Abstract

The invention provides an emergency early warning method for stampede accident in a public area, the method comprises the steps: picture or video information of people flow in the public area is shot in real time and sent to a local police station monitoring center; the picture or video information is converted into people flow data information and a people density value in the local police station monitoring center; and a substation management server can process the people flow data information and the people density value and judges the actions of alarming. According to the invention, public area precise number of people can be counted according to people flow data of public area inlet and outlet or passageway and people density value of public area, the counted public area precise number of people can be analyzed in real time, if the value reaches a preset alarm threshold value, the police who manage the substation management server can be timely notified, so that the urgent evacuation can be realized, the stampede accident can be avoided; and the method can comprehensively monitor people flow in public area and precisely count number data of people, the jam condition can be avoided, and the practicability is strong.

Description

technical field [0001] The invention relates to the technical field of anti-stampede early warning, in particular to an emergency early warning method for crowding and stampede events in public areas. Background technique [0002] With the advancement of economic and social development and urbanization, there are more and more occasions where people gather and large-scale events are held in cities, including sports events, music festivals, art exhibitions, large-scale amusement parks, etc. Large-scale amusement parks and exhibitions have also been built in cities Centers, such as Shanghai Disney Resort and China International Exhibition Center. The population density in these areas has increased exponentially, and large-scale crowd gatherings can easily lead to accidents such as crowd stampedes. Crowd stampede refers to a catastrophic event in which when a large number of people are moving in a relatively crowded space, uncontrollable disorder occurs due to some reason, res...
