Epidemic infectious disease virus field visualization method and system based on space-time trajectory data

Abstract

The invention discloses an epidemic infectious disease virus field visualization method based on space-time trajectory data. The method comprises the following steps: S1, airspread infectious diseaseurban diffusion modeling; s2, collecting, cleaning and processing space-time trajectory data and infection attack data of virus carrying crowds; s3, obtaining position semantic information of a viruscarrier; s4, calculating the virus distribution density by taking the virus carrier as the position center; s5, mapping the time, space and virus distribution density data of the virus carrying population; and S6, constructing an epidemic infectious disease virus field cloud platform based on temporal GIS. The invention further provides an epidemic infectious disease virus field visualization system based on the space-time trajectory data. According to the method, space-time trajectory data and infection attack data of virus carrying crowds are processed into a virus distribution density map with the virus carrier as the position center, spatial position semantic information is added and mapped to a temporal GIS, and an epidemic infectious disease virus field is visually processed.

Description

technical field [0001] The invention relates to the application of mobile phone positioning, temporal GIS, big data and cloud computing in the field of prevention and control of epidemic infectious diseases, in particular to a method and system for visualizing virus field of epidemic infectious diseases based on spatiotemporal trajectory data. Background technique [0002] The core of an infectious disease outbreak lies in its contagiousness, which can be transmitted directly or indirectly from one person to another or more people. To deal with such sudden outbreaks of infectious diseases, humans have mastered a very old but extremely effective method-that is, isolation. [0003] There are three cores of isolation: [0004] The first is to find and manage the source of infection. Scientists have confirmed that the new coronavirus is the pathogen of this infectious disease outbreak, and it can spread from person to person, so the rapid identification and isolation of those ...

Problems solved by technology

[0010] This 2019-nCoV infectious disease is very occult; ①The coronavirus is nano-scale, invisible to the naked eye, and has a long incubation period; ②The symptoms are not obvious, and the incubation period of infection is also obviously infectious; ③ Asymptomatic infections are also contagious to a certain extent, which brings new challenges to the prevention and control of the epidemic;
