Description
Technical Field
The invention relates to the scientific field of atmospheric environment monitoring, in particular to an active atmospheric ozone vertical observation system based on a multi-rotor unmanned aerial vehicle platform.
Background
Ozone is an important air pollutant in the near-ground atmosphere, and the higher ozone concentration level can not only seriously threaten the physical and psychological health safety of people, but also cause large-area yield reduction of crops and accelerate the aging speed of building materials. In addition, ozone is also an important greenhouse gas. At present, relatively perfect atmospheric environment quality monitoring networks are established in various cities throughout the country, so that the ozone concentration in near-ground atmosphere in different regions can be obtained in time, and necessary actual measurement data support is provided for formulation and implementation of ozone pollution prevention and control measures.
Ozone molecules in the near-surface atmosphere originate mainly from local photochemical reactions and are also significantly affected by the external transport processes of different types of ozone. Therefore, when a main formation mechanism of an ozone pollution process in the near-ground atmosphere of a research area is researched, observation data only depending on a ground environment monitoring station is far from enough, and the vertical distribution structure of the ozone concentration in the atmosphere at the bottom of the convection layer and development evolution rule data of the vertical distribution structure need to be acquired at the same time. The vertical observation data of the ozone concentration is helpful for analyzing the external sources of ozone molecules in the atmospheric boundary layer, determining the main external conveying channel of ozone pollution in the research area, and further is helpful for analyzing the main forming mechanism of the typical ozone pollution process in the near-surface atmosphere.
In recent years, the rapid development of civil unmanned aerial vehicle technology and industry provides a new vertical observation means for the research of the air pollution process in the atmosphere at the bottom of the current layer. The development of the miniaturized active air pollutant monitoring equipment also lays a solid technical foundation for the use and development of the unmanned aerial vehicle atmospheric environment monitoring platform. Compare with vertical observation platforms such as traditional captive balloon, sounding balloon, ozone laser radar and manned aircraft, unmanned aerial vehicle vertical observation platform's flexible flexibility is higher, can accomplish the vertical observation task of ozone in troposphere bottom atmosphere under complicated terrain environment to have lower operation and maintenance cost.
Unmanned aerial vehicle atmospheric environment monitoring platform in the past mainly uses passive ozone sensor, is about to install miniature electrochemistry ozone sensor on unmanned aerial vehicle, acquires the ozone concentration of different height departments in the ambient atmosphere passively. However, the response time of the passive electrochemical ozone sensor is generally long, and the accuracy of the observation data is generally poor, so that the requirement of research on the vertical distribution of ozone in the atmosphere at the bottom of the troposphere is difficult to meet. Aiming at the problem, a miniaturized active ozone monitoring device is introduced, the same measurement principle as that of the traditional large-scale device is adopted, the ozone concentration value in the ambient atmosphere can be rapidly and accurately obtained, and the device has higher sampling precision and reliability. However, one challenge that comes with this is that in the atmosphere at the bottom of the troposphere, meteorological parameters (such as temperature, humidity, wind direction and velocity, etc.) fluctuate widely in the vertical direction, causing significant deviations in the measurement results of the ozone monitoring device. Therefore, when active ozone monitoring facilities of miniaturization uses on unmanned aerial vehicle atmospheric environment monitoring platform, very crucial one point lies in need to be directed against the corresponding perpendicular observation system of operating characteristic design of unmanned aerial vehicle platform to guarantee the quality of ozone perpendicular observation data.
