Method and system for monitoring air pollution source SO2 based on UAV

Abstract

An embodiment of the present invention provides a method and system for monitoring an air pollution source SO2 based on a UAV (unmanned aerial vehicle). The method comprises a step of processing an ultraviolet imaging spectrum image acquired by the UAV and the flight attitude information of the UAV through the differential absorption spectroscopy technology to obtain a SO2 exceeding standard emission discrimination standard of an industrial gathering area to be tested, a step of performing inversion processing on the ultraviolet imaging spectrum image according to a principal component analysis algorithm to obtain an SO2 exceeding standard emission inversion result of the industrial gathering area to be tested, and a step of identifying the SO2 exceeding standard emission inversion resultaccording to the SO2 exceeding standard emission discrimination standard so as to obtain a SO2 exceeding standard discharge area of the industrial gathering area to be tested. The embodiment of the invention can quickly respond to the excessive emission of the air pollution source SO2, so that the atmospheric environment pollution can be monitored in real time, the timeliness is strong, and the precision is high.

Description

technical field [0001] The invention relates to the technical field of air pollution monitoring, in particular to an air pollution source SO based on a drone 2 Monitoring method and system. Background technique [0002] Atmospheric environment monitoring is the most important basic work in environmental protection work. Therefore, atmospheric emission and pollution monitoring in key chemical parks has become the daily work of environmental protection departments at all levels. The traditional monitoring of chemical air pollution in the environmental protection system is mainly based on manual monitoring on the ground at regular and fixed points. In view of the hidden nature of chemical air pollution discharge and the sudden nature of pollution accidents, traditional ground monitoring methods are difficult to meet the needs of environmental protection departments. [0003] At present, many environmental protection departments have used remote sensing technology as the main m...

Problems solved by technology

The traditional monitoring of chemical air pollution in the environmental protection system is mainly based on regular and fixed-point ground manual monitoring. In view of the concealment of chemical air pollution emissions and the suddenness of pollution accidents, traditional ground monitoring methods are difficult to meet the needs of environmental protection departments.

[0003] At present, many environmental protection departments have used remote sensing technology as the main means of monitoring regional air pollution, mainly conducting monitoring and research on indicators such as particle concentration, temperature, humidity, and pressure. As an important source of air pollution, SO 2 Excessive discharge pollution monitoring is still in the exploratory stage
