Abstract

The invention discloses a UAV (unmanned aerial vehicle) loading based DOAS (differential optical absorption spectroscopy) detection method for high-emission typical pollutants. When high-emission gasenters a gas chamber, a control center turns on a light source, light emitted by the light source enters the gas chamber, light coming out of the gas chamber enters a spectrograph, the spectrograph collects a spectrum, and the control center stores data in data storage equipment. The method is high in precision, pollutants are measured with DOAS, and high precision is realized as compared with physical or chemical detection. The requirement for upper detection limit of a detection device is high in a specific environment such as a high-emission enterprise, and the problem can just be solved with spectroscopy. Next, high altitude pollution of a high-emission enterprise environment can be monitored at any time with the method, a UAV is used as a carrier, air pollution condition especially insurrounding of the high-emission enterprise can be obtained quickly in real time, and the method can be used by a supervision department for remote monitoring. Finally, an independently researched and developed operation system is provided, and real-time control can be realized through an electronic screen.

Description

【Technical field】 [0001] The invention relates to a differential absorption spectrum detection method of high-emission typical pollutants carried by an unmanned aerial vehicle. 【Background technique】 [0002] At present, with the increase of social development and population, energy consumption is increasing. Although there are new energy sources and renewable energy sources, coal and oil are still the main energy consumption products of human society. The use of coal and petroleum has also brought environmental degradation and ecological damage to many countries and cities. Air pollution in typical areas of high-emission enterprises across the country is becoming more and more serious, and there are technical difficulties such as regionalization and complexity in environmental testing of high-emission enterprises. [0003] At present, the environmental monitoring methods of high-emission enterprises in China mainly include manual monitoring and fixed monitoring. Tradition...
