Sonde emitter structure based on unmanned aerial vehicle carrying

Abstract

The invention discloses a sonde emitter structure based on unmanned aerial vehicle carrying. The structure comprises a top plate and an emitter body, the part, close to the edge, of the lower surface of the top plate is fixedly connected with the top end of a protection cover, the protection cover is streamlined, the contact part between the protection cover and the top plate is in arc transition, the emitter body is arranged in the protection cover, the top of the emitter body is hinged to the lower surface of a top plate through a hinged support, an adjusting part is arranged between the emitter body close to the top wall of the hinged support and the lower surface of the top plate, the tail end of the protective cover is a separable rear end part, and the top end of the rear end part is fixedly connected with the lower surface of a movable end. And the movable end and the rear end part are spliced with the protective cover and the top plate respectively. The situation that the emitter is exposed outside for a long time, the surface of the emitter is easily covered by condensed water under the condition that the humidity in the air is relatively high, the strength of a transmitted signal is influenced, and data acquisition is influenced is avoided.

Description

technical field [0001] The invention relates to the technical field of radiosonde launchers, in particular to a radiosonde launcher structure based on unmanned aerial vehicles. Background technique [0002] The radiosonde can transmit the detected meteorological data at the altitude to the ground at any time. The radiosonde weighing less than 1 kg is mainly composed of four parts: sensing element, conversion device, transmitter and power supply. The sensing element is used to sense the size and change of atmospheric temperature, pressure, and humidity elements; then it is converted into a radio signal corresponding to the detection amount through a conversion device; and the high-frequency radio oscillation (carrier ), it can carry the detection signal and send it to the ground; the power supply provides the energy source of the entire radiosonde, and it occupies a considerable weight. The sensing element (or sensor) is a key component of the radiosonde. Compared with the ...

Problems solved by technology

[0003] Airsondes are generally carried into the air by weather balloons or UAVs for detection. At present, UAVs are generally used. UAVs can be carried more safely and quickly to measure a certain area, while the existing ones generally directly Fixing the radiosonde on the drone, because the shape of the radiosonde transmitter does not conform to the aerodynamic shape, it is easy to increase the difficulty of controlling the drone, which affects the accuracy of the radiosonde detection, and the transmitter is exposed for a long time Outside, when the humidity in the air is high, the surface is easily covered by condensed water, which affects the strength of the transmitted signal and affects data collection.
