Problems solved by technology

The two methods have been widely used in the research of air pollution transmission and diffusion in different regions in China. However, due to the difficulty in obtaining real-time and accurate meteorological grid data in different regions, the application of Lagrangian model is applied in real-time traceability of small-scale pollution. less
[0004] Existing pollution traceability technology and related platforms have many nested models, complex processes, slow computing speed, low spatial resolution, and low accuracy of forecast results. Law enforcement management departments cannot enforce laws in a timely, accurate, and efficient manner.

Abstract

The invention provides a vehicle-mounted Lagrangian real-time air pollution traceability system and method based on a cloud platform, which relates to the technical field of air pollution prevention and control. Vehicle-mounted Lagrangian real-time air pollution traceability system and method based on cloud platform, The high-precision WRF weather model base on the high-performance cloud platformis constructed, Lagrangian particle release model, and through the design and front-end transfer platform, GPS positioning system closely combined to build a vehicle-borne mobile pollution traceability system, effectively improve the emergency response capacity and law enforcement of the relevant departments of the rapid and accurate.

Description

technical field [0001] The invention relates to the technical field of air pollution prevention and control, in particular to a Lagrangian real-time air pollution traceability system and method based on cloud platform high-performance computing and mounted on a vehicle-mounted mobile platform. Background technique [0002] With the development of society and economy, the impact of urban industry, transportation, electric power and residents' life on urban air quality is increasing day by day. Air quality has also attracted more and more attention from the general public, and the relevant environmental departments have increasingly strengthened the supervision of urban air pollution. Due to the development of urban industry and economy, enterprises are pursuing the maximization of interests, disregarding relevant laws and regulations, and unorganized discharge of pollutants has been repeatedly prohibited. Therefore, accurate, fast and real-time pollution traceability technolo...
