Problems solved by technology

The inertial navigation module is the core part of the flight of multi-rotor drones. If there is a problem with this module, the multi-rotor drones cannot fly normally, resulting in a decrease in the reliability and safety of the multi-rotor drones.
Due to problems such as the installation position of the attitude sensor or the center of gravity of the multi-rotor UAV, the attitude of the trim point is not 0, and it will drift in a certain direction when the remote control is not used.
When the battery power of the multi-rotor UAV is low, the altitude control is unstable and it is easy to fall

Abstract

The invention discloses a radiosondage system based on a dual-redundancy six-rotor unmanned aerial vehicle. The system comprises a six-rotor unmanned aerial vehicle, a radio sonde and an earth station. The six-rotor unmanned aerial vehicle drives the radio sonde to rise, and the radio sonde transmits the collected data to the earth station processing. According to the system, a dual-redundancy sensor is used, and the reliability and security of the flight of the six-rotor unmanned aerial vehicle are improved. The earth station and a wireless data transmission module are added, and the course of automatic flight can be modified at any time. The radiosondage system is used for developing all-weather high resolution atmosphere boundary layer detection, while the integrity of detection data is ensured, the expense of human power can be reduced, and the system is a feasible substitution scheme for a present atmosphere boundary layer detection common mean.

Description

technical field [0001] The invention relates to a radiosonde system based on a dual-redundancy six-rotor UAV, and belongs to the technical field of meteorological detection. Background technique [0002] The atmospheric boundary layer is the main layer of human activities and various ecological environments, and it is the air layer that must pass through the exchange of momentum, heat and material properties between the earth's surface and the free atmosphere. Most of the major meteorological experiments at home and abroad take the study of the atmospheric boundary layer as one of the core scientific contents, and the meteorological elements detected generally include temperature, humidity, air pressure, wind speed, and wind direction. [0003] Atmospheric boundary layer detection can be carried out relying on existing upper-air weather stations. High-altitude meteorological stations are places established by meteorological departments on land or at sea to carry out high-al...
