Design Of Meteorological Elements Detection Platform For Atmospheric Boundary Layer Based On UAV

In view of the current atmospheric boundary layer detecting method, the sounding balloon has difficult to recover and has low repetition rate, the anemometer tower has fixed position and high cost, and the remote sensing has low data accuracy.In this paper, the six-rotor unmanned aerial vehicle (UAV) flight control technology and meteorological element detection technology combined to study the atmospheric boundary layer of meteorological elements detection.. This design can realize the function of detecting high precision, continuous use and vertical takeoff and landing.It is a direct measurement method for atmospheric detection.. In some cases can make up for sounding balloons, wind towers, remote sensing detection of the existing problems.Therefore, this paper is closely linked with the practical application, studied the design and application of the atmospheric boundary layer detection system based on rotor UAV, the main contents include: First, through the design of the mechanical structure design and control system of the six-rotor unmanned aerial vehicle, a six-rotor unmanned aerial vehicle is built; Secondly, through the design of the meteorological element detection system, information such as temperature, relative humidity, air pressure, elevation and latitude and longitude are realized ; And then data management, including SD card storage and the real-time display of upper computer; Finally, combined with automatic weather station data comprehensive analysis to verify the effectiveness of the data. Aiming at the influence of the rotor wind on the detection accuracy of the meteorological sensor in the process of the atmospheric boundary layer, the installation position of the sensor is spatially higher than that of the propeller plane, and the influence of the rotor wind is the least.Experiments show that this paper through the UAV platform equipped with meteorological elements detection system has been achieved on the temperature,relative humidity, pressure, altitude and latitude and longitude data SD card storage and upper computer real-time display, and compared with the automatic weather station data analysis of meteorological elements of accuracy, among them,temperature accuracy:?T?0.5?; humidity accuracy:?U?6RH%; pressure accuracy:?P?5hPa, to meet the needs of atmospheric detection applications.
