Description

Technical Field

[0001] The present invention relates to the technical field of multi-source data analysis, and in particular to a visual analysis system and method for factors affecting the public health of urban residents combined with multi-source data. Background Art

[0002] As the urban population grows, the amount of garbage generated also increases. In order to facilitate cleaning, the garbage of urban residents is often placed in a unified garbage collection point and cleaned up in a community. However, the garbage is sometimes not cleaned up in time, causing health hazards to residents in the community. Multi-source data can easily evaluate the impact of garbage at garbage collection points on residents. Therefore, it is necessary to analyze the factors affecting the public health of urban residents based on multi-source data.

[0003] The prior art, such as the invention patent application with announcement number: CN113362960B, discloses a visual analysis system and method for urban residents' public health influencing factors combined with multi-source data. The system includes: a multi-source data acquisition module for collecting physical examination report information and multi-source livelihood data, a multi-source data analysis module for analyzing the collected physical examination report information and multi-source livelihood data, and a disease mining and analysis module for mining and analyzing diseases based on the physical examination report information and multi-source livelihood data. This invention can provide analysis basis and platform support for residents' health monitoring, disease popularization and prevention, and urban health management.

[0004] Prior art, such as the BIM-based demolition project pollution prediction and optimization system disclosed in the invention patent application with announcement number: CN117610261A, includes: This invention uses BIM to model the building information, uses computer numerical simulation technology to build a digital model of pollution diffusion, and analyzes factors, adopts the optimization scheme principle, optimizes the construction plan and makes a construction plan optimization report, to ensure that the dust generated by building demolition and blasting projects will not affect the life and health of on-site construction workers and residents in surrounding areas, and maximize the reduction of air quality pollution in the entire area. Secondly, it ensures that the dust generated by building demolition and blasting projects will not affect the quality of life of surrounding residents and the physical and mental health of on-site construction workers.

[0005] It can be seen from the above scheme that the current visual analysis system of factors affecting the public health of urban residents lacks a certain attention to analyzing the harm of garbage collection points in various communities in the city to residents. In actual construction, garbage collection points are often built outside the community and within a certain range of the community entrance and exit, so as to facilitate the transportation of garbage within the community. However, the garbage collection points in some communities are built too close. When there is a large amount of garbage at the garbage collection points and under the influence of wind speed and wind direction at the garbage collection points, residents entering at the entrances and exits of the community are easily affected by the harmful gas cadaverine produced by the garbage collection points, thereby affecting the physical and mental health of the residents. At the same time, there is a lack of attention to the assessment and treatment of the pollution level of garbage collection points. With the continuous construction of some communities, the original garbage collection points are prone to be too close to the entrances and exits of the community. The entrances and exits of the community are places that residents must pass through when entering and exiting. Long-term contact with garbage collection points is likely to endanger the physical and mental health of residents. Summary of the invention
