Air-pollution detecting method

Abstract

The invention relates to an air-pollution detecting method, comprising an image digitized device, an image processing computer and an image output device, wherein, the image digitized device is connected with the image processing computer, the image processing computer is connected with the image output device; firstly, the picture file format is led into the image digitized device, the coloring information of pixel points of the picture is obtained and input into the image processing computer for gray-scale processing, then subtraction processing of smoke-free default for gray-scale processing results in the setting area is conducted, the number of the pixel points in the threshold range is calculated, lastly, the judgment that whether smoke is discharged is provided, and the analysis progress is displayed in the image output device in percentage. Compared with the prior art, the invention has characteristics of good monitoring intensity, less human expenditure, and wide application range.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an air pollution detection method. Background technique [0002] At present, when many projects are inspected by the environmental protection department, in order to avoid the problem of exhaust emissions, production is stopped, but as soon as the inspectors of the environmental protection department leave, they immediately resume production. Years of pollution. The root cause lies in the time constraints, heavy tasks, difficult investigations, and difficulty in reconciling monitoring efforts and expenditures that environmental protection departments in various regions generally face. [0003] Judging from the current status of industrial chimney smoke monitoring at home and abroad, the following two monitoring modes are mainly used in parallel. For the monitoring of chimneys in several industrial production areas, select several commanding heights to install and debug s...

AI Technical Summary

Problems solved by technology

For the monitoring of chimneys in several industrial production areas, select several commanding heights to install and debug smoke remote sensing continuous automatic monitoring devices, take smoke particles as the sample collection object, and conduct in-depth composition analysis on them, supplemented by road manual inspection of remote sensing blind areas Inspection, technology and operating costs are relatively high, and the scope of application is relatively concentrated

For the monitoring of relatively independent chimneys, the monitoring personnel use special soot blackness testing telescopes to conduct manual inspections, which requires a large amount of manpower and limited monitoring frequency
