Design Of Carrying Platform Of Radiosonde For Boundary Layer Based On Four Axis Aircraft

Radiosonde is one of the important means for the meteorological element detecting of the atmospheric boundary Layer. However the existed radiosonde is difficult to recycle which may cause great waste and generate risk of public safety. As four-axis aircraft has the advantages of simple structure, flexible action and good operation, this article proposes a design scheme utilizing a four-axis aircraft with radiosonde to detect, thus making effort to improving the detection effect of radiosonde.This article first introduces the related technology of four axis aircraft particularly. Then according to the demand, choose the appropriate frame structure and completed the design of the flight control circuit board and the flight control software. At the same time, the temperature, humidity sensor, pressure sensor and GPS module are integrated in the control circuit board to realize the detection and acquisition of the meteorological elements. The system use NRF24L01 and realizes the transmission of meteorological elements and the flight data and control instructions through 2.4G communication network.In the laboratory and out-field environment. We complete the trail flight and communication function test to verify that the four-axis aircraft has achieved the anticipated functions.
