Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Grid supervision originally originated from "grid social governance". When the prevention and control of air pollution enters the tough battle in 2017, according to the need for more refined pollution prevention and control supervision, key areas, key areas, key industries and key areas need to be highlighted. The current status of air pollutant emissions d...

Abstract

The invention discloses a pollution source prevention and control hotspot grid supervision method and system, and solves the problems of high cost, low supervision accuracy and insustainability of anexisting method and system. The method comprises the following steps: marking an emission source of an observation area; classifying, screening and positioning the emission source to obtain a thermalabnormal point, a nitrogen dioxide hot spot, an aerosol distribution hot spot and a naked dust source hot spot; dividing the observation area into primary grids, superposing the thermal anomaly point,the nitrogen dioxide hot spot, the aerosol distribution hot spot and the naked dust source hot spot, removing grids without superposed hot spot data, refining grid units of the hot spots with superposed data to obtain secondary grids, and removing grids without superposed hot spot data in the secondary grids to obtain a hotspot grid distribution result of the observation area; and carrying out thermal anomaly point, aerosol and nitrogen dioxide concentration monitoring on the emission source in the hot spot grid. The system uses the method. According to the invention, emission source grid supervision is realized.

Description

technical field [0001] The invention relates to the field of satellite remote sensing, in particular to a grid supervision method and system for pollution source prevention and control hotspots. Background technique [0002] The existing hotspot grid emission source monitoring method is based on the installation of air quality micro-stations in the grid points, and uses the changes in the air quality data of the micro-station monitoring points to identify the air quality change problem of each grid. The air quality sub-stations or micro-stations used in grid management have the characteristics of monitoring data drift and data quality uncertainty, which often easily cause false alarms, although the cost of air quality micro-stations is lower than the standard monitoring equipment of national control stations However, air quality micro-stations need to be installed in each grid, resulting in a huge amount of data, high cost, high cost, unsustainable, and unsuitable for nation...
