Airborne aerosol particle vertical observation system based on unmanned aerial vehicle, and airborne aerosol particle vertical observation sampling method

Abstract

The invention discloses an airborne aerosol particle vertical observation system based on an unmanned aerial vehicle, and an airborne aerosol particle vertical observation sampling method, the systemcomprises an unmanned aerial vehicle airborne platform system, an unmanned aerial vehicle ground control platform, a ground data collecting and processing center system and a ground data collection and comparison system; the sampling method comprises: causing a four-bladed propeller light-weight unmanned aerial vehicle to perform automatic hovering and flying according to a preset height and routewhile carrying a portable laser pump type aerosol particle parameter measuring instrument, various weather sensors and an optical image shooting device, the mass concentration and number concentration of vertical atmospheric aerosol particles in a specific target airspace, and atmospheric environment parameters such as temperature, pressure, humidity and the like, and optical image data can be continuously measured, the collected data are sent to the ground data collecting and processing center through a wireless protocol, and the ground data collection and comparison system completes the display, analysis and processing of the data after performing quality control. The entire system is compact in structure, easy to control and adjust, high in system stability and low in cost.

Description

technical field [0001] The invention relates to the field of meteorology, in particular to an aerosol particle vertical observation system and sampling method based on an unmanned aerial vehicle. Background technique [0002] With the acceleration of urbanization, the pressure of urban life, production and transportation is increasing, and urban air quality is also affected in different degrees. The decline of air quality can affect the performance of urban functions and cause serious harm to residents' life, production activities and health. Atmospheric aerosol refers to a stable mixed system composed of solid and liquid particles dispersed in the atmosphere, and the particle diameter is generally between 0.001-100. Aerosols play an important role in the overall atmospheric radiation balance. Aerosols have a greater impact on precipitation, hail and haze by absorbing and scattering solar radiation. Regarding the observation of aerosol particles, conventional observations ...
