Atmospheric composition sampling system

Abstract

The invention relates to an atmospheric composition sampling system, and belongs to the technical field of atmospheric monitoring.The sampling system comprises a ground mobile power supply device, an aircraft and a sampling device, wherein the ground mobile power supply device and the aircraft are connected through a cable, and the sampling device is connected to the aircraft; a cable winding device used for cable winding and unwinding is arranged in the ground mobile power supply device, the sampling device comprises a controller, a rotary-type air collection mechanism which achieves positioning by means of a cradle head and a group of air samplers, the air samplers form a time-sharing and multi-parameter sampling mechanism to atmospheric compositions by means of control of the controller over the rotary-type air collection mechanism, and the air samplers have multiple types.When the sampling system works, multi-position and multi-item atmospheric composition sampling work can be achieved through one-time taking off, the efficiency is greatly improved, time intervals of sampling work between different positions are short, atmospheric composition data at different positions within a short time range can be provided, and the reference to research is good.

Description

technical field [0001] The invention belongs to the technical field of atmospheric monitoring, and in particular relates to an atmospheric composition sampling system. Background technique [0002] The atmospheric boundary layer is the vertical air layer that is most directly affected by the surface. In recent decades, due to the increasingly serious air pollution in cities, the impact of human activities on the atmospheric environment has become more and more obvious, and people have paid more and more attention to the impact of cities on the environment and the atmosphere. Thus promoting the study of the urban atmospheric boundary layer. Through the analysis of the main pollutants in the atmospheric boundary layer, such as the analysis of the concentration of total suspended particulate matter, sulfur dioxide, nitrogen oxides, etc., the pollution situation of the atmospheric boundary layer can be grasped more accurately. [0003] At present, the main method of observing a...

Problems solved by technology

[0004] Multi-rotor aircraft can obtain data in various aspects by carrying a variety of sensors, but the energy storage strength per unit mass of the battery is very limited, and the endurance time must be extended by increasing the number of batteries, and the weight of the battery itself greatly reduces the weight of the aircraft. Load capacity, the aircraft can only carry small cameras or sensors for short-term flight, which cannot meet the requirements of long-term flight

The patent document with the application number 201210597187.9 discloses a cable-powered multi-rotor aircraft system. Although this patent proposes the idea of ​​using cables to supply power to the aircraft to achieve long-term flight, the power supply system uses ground to meet the needs of brushless motors. Low-voltage transmission of electric energy cannot meet the power supply requirements of large-load and high-power aircraft; the patent document with application number 201320011037.5 discloses an airborne air sampling device, which is mainly used to collect aerosols and small molecular particles in the atmosphere, and cannot To collect other components in the air, only one sample can be collected at a time, with single function and low efficiency
