An emergency evacuation method and system for urban gathering events

Abstract

The invention relates to the technical field of urban emergency evacuation, in particular to an emergency evacuation method and system for urban gathering events. The evacuation device used in the method includes a bracket, a camera, a speaker and a controller; one end of the bracket is fixedly connected to the On the ground, the other end is rotatably connected with a disc; the outer wall of the disc is set in a tooth shape; the outer wall of the other end of the bracket is fixedly connected with a motor; the output shaft of the motor is connected with a gear; An emergency evacuation method for urban gathering events and the evacuation device used in the system drive the camera to rotate around the other end of the bracket through a motor, and then cooperate with the controller to control the horn to make synchronous sound, thereby expanding the shooting range of the camera. At the same time, it also improves the clarity of people receiving the sound from the horn, so that people can obtain the fastest evacuation route, thereby improving the efficiency of people's emergency evacuation.

Description

technical field [0001] The invention relates to the technical field of urban emergency evacuation, in particular to an emergency evacuation method and system for urban gathering events. Background technique [0002] In recent years, with the rapid development of the urban economy, the urban population has been increasing, and it has already shown a high-density and high-flow population state. Pedestrian streets refer to the pedestrian lanes set up in the central area of ​​​​the city where traffic is concentrated, and gradually formed. In principle, car traffic is excluded here, and there is a parking lot on the periphery, which is a pedestrian priority activity area; the pedestrian street has the same meaning as the pedestrian shopping street and can be generally called a pedestrian street; the pedestrian street is part of the urban pedestrian system to revitalize the old area. , An urban construction method adopted to restore the vitality of the central area of ​​the city a...

Problems solved by technology

[0002] In recent years, with the rapid development of the urban economy, the urban population has continued to grow, showing a state of high-density, high-flowing population. Pedestrian streets refer to pedestrian-only lanes set up in the central area of ​​the city where traffic is concentrated, and gradually form In principle, car traffic is excluded here, and a parking lot is set up outside, which is a priority activity area for pedestrians; pedestrian street and pedestrian shopping street have the same meaning and can be called pedestrian street; pedestrian street is part of the urban pedestrian system to revitalize the old district , an urban construction method adopted to restore the vitality of the city center and protect traditional blocks; with the improvement of people's living standards, more and more people will pour into the pedestrian street shopping frenzy, which will make the pedestrian street densely populated; when the pedestrian street When an emergency occurs in a commercial block, such as fire and crime, due to the lack of existing technology, people do not know the congestion at the intersections at both ends of the pedestrian street, so that people do not know which direction to evacuate from the road, resulting in The inefficiency of people's emergency evacuation affects people's lives and property safety

[0003] In the prior art, there are also some technical solutions on emergency evacuation methods and systems for urban gathering events. For example, a patent with application number CN201911289214.4 discloses an emergency evacuation method and system for urban gathering events, including : Step a: Use basic geographic surveying and mapping data to construct urban multi-modal traffic system; Step b: Estimating the temporal and spatial distribution of urban agglomerated population based on mobile phone signaling big data; Step c: Estimating urban road congestion status based on floating vehicle GPS trajectory data; Step d : Estimating the passenger capacity of buses and subways based on smart card swiping data; step e: constructing an emergency evacuation optimization model in conjunction with the multi-modal traffic system, the spatial-temporal distribution of urban agglomeration population, the state of urban road congestion, and the passenger capacity of buses and subways, And use the heuristic algorithm to solve the emergency evacuation optimization model, and obtain the multi-traffic evacuation strategy of the gathering event; this technical solution can effectively guide the gathering crowd, dispatch vehicles, avoid congestion, and provide decision-making support for the emergency management department or the transportation department; but the However, the technical solution cannot accurately obtain the density of people at both ends of the intersection of pedestrian streets and commercial roads, so that people do not know which direction to evacuate from the road, thus missing the best evacuation time, affecting people's lives and property safety, and causing the Program limitations
