Crowd density monitoring method and device based on Wifi network

Abstract

The invention relates to a crowd density monitoring method and device based on a Wifi network. The method includes the following steps that firstly, each terminal collects real-time position information of itself, and the collected position information is sent to a position sensing unit through the Wifi network; secondly, the position sensing unit receives the position information sent by the multiple terminals, integrates all the position information and sends the position information to a server; thirdly, the server analyzes and processes all the position information, calculates crowd density and flow information, and displays the crowd density and flow information in a graphical mode; fourthly, the server calculates countdown, and the first step is executed after countdown is over. All the position information of users is collected in real time, can be converted into visual graphic interfaces, and is provided for managers for conducting intervention, adjustment and taking other emergency measures in time, malignant mass incidents such as meaningless crowding and stampede are avoided, and safety can be improved under the current social environment.

Description

technical field [0001] The present invention relates to a densely populated monitoring device, in particular to a Wifi network-based densely populated monitoring method and device. [0002] Background technique [0003] Crowding and stampede incidents occur in public places due to excessive density or excessive flow of people. [0004] The causes of such crowding and stampede incidents are in a large crowd gathering environment. When the local density is too high (more than 3-4 people per square meter), it will lead to hypoxia and panic. The former will make the weak easily fall and get injured. , and the latter will make the crowd lose their minds and increase the difficulty of rescue and evacuation. According to the investigation results of previous similar accidents, it can be known that there are signs for each accident, and the overall crowd density and local crowd density are necessary conditions. There is usually a period of time between the onset of symptoms of an...
