Abstract

The invention provides an epidemic situation risk grade assessment method based on people flow density. The method comprises: acquiring the number of total newly-added definite cases of a target district / county and the number of locally-added definite cases of the target district / county; acquiring the population flow data of the target district / county according to Tencent position big data; acquiring the population density of the target district / county; acquiring the enterprise data of the target district / county according to the POI data of Amap; inputting the total number of the newly-added definite cases, the number of the locally-added definite cases, the population flow data, the population density and the enterprise data into an epidemic situation risk assessment model, and acquiringthe epidemic situation risk assessment grade of the target district / county; and inputting the epidemic situation risk assessment grade of the target district / county into a geographic information system to obtain the epidemic situation risk assessment map of the target province, and presenting the epidemic situation risk assessment map to a user. Compared with the prior art, the method of the invention has the advantage that the district / county scale epidemic situation risk grade can be evaluated accurately.

Description

technical field [0001] The invention relates to the field of data analysis, in particular to a method for assessing the risk level of an epidemic situation based on crowd density. Background technique [0002] Recently, affected by the Corona Virus Disease 2019 (COVID-19) epidemic, the field of labor relations is facing new situations and new problems. Enterprises in some industries are facing greater pressure on production and operation, and workers are facing waiting for work, unemployment, and income reduction. and other risks, while directly affecting the lives of the masses. Under such circumstances, it is urgent to conduct a comprehensive assessment of the epidemic risk in each district / county, so as to realize the scientific and accurate division of the prevention and control level of the district / county, and realize the corresponding differentiated prevention and control management. [0003] The current assessment of the epidemic risk level is mainly based on the ci...
