Abstract

The invention discloses an urban public space stampede accident real-time early warning method based on mobile phone positioning data, and belongs to the technical field of urban accident early warning. Collection processing is performed on real-time data of mobile phone base stations within the range of urban public space, flow density of the urban public space is obtained by calculation through the steps of data cleaning, space connection, data mapping and reallocation of the number of mobile phone users based on space area, and an early warning or alarm signal is emitted timely. The processing method is simple and practicable and convenient for real-time monitoring of the crowd density of the urban public space so that the stampede accident caused by local overpopulation of the urban public space can be avoided. With application of the method, early warning of the stampede accident of the urban public space can be performed in real time and related personnel can be timely prompted to start emergency measures so that the method has the actual social application value and can reduce the harm caused by the stampede accident.

Description

Technical field [0001] The invention belongs to the technical field of urban accident early warning, and specifically relates to a real-time early warning method for trampling accidents in urban public spaces based on mobile phone positioning data. Background technique [0002] Urban public space is an important place and carrier of civic activities. It mainly includes open (outdoor) public space and enclosed (indoor) public space. Open public spaces mainly include green parks and civic squares. Closed public spaces mainly Including exhibition halls, stadiums, cultural centers, important transportation hubs (train stations, bus stations, airports, etc.). In recent years, with the enhancement of my country's comprehensive national strength, citizens' living standards have gradually improved, urban public service facilities have been gradually improved, and cities have built a large number of high-quality public spaces, greatly enriching the people's material and spiritual lives. ...
