A low-altitude flight-altitude control system for soft-wing unmanned aerial vehicles

Abstract

The invention discloses a low-altitude flight fixed-height control system for a soft-wing unmanned plane and belongs to the field of soft-wing unmanned plane flight. The system comprises a ram parafoil, a power unit, a master control processor, height measurement equipment and a throttle adjusting unit, the ram parafoil is arranged at the top of a cabin of the soft-wing unmanned plane, the height measurement equipment is used for measuring the actual altitude of the soft-wing unmanned plane, the power unit comprises an engine and a propeller connected with the engine, the propeller is arranged at the tail of the cabin, the throttle adjusting unit is connected with the engine of the power unit so that the amount of fuel oil input into the engine can be adjusted, and the master control processor is arranged in the cabin and electrically connected with the throttle adjusting unit and the height measurement equipment at the same time so that the throttle adjusting unit can be controlled, the amount of fuel oil input into the engine can be further adjusted and the actual altitude of the soft-wing unmanned plane can be acquired from the height measurement equipment. By means of the control system, fixed-height flight of the soft-wing unmanned plane can be controlled accurately.

Description

technical field [0001] The invention belongs to the field of altitude determination control for soft-wing unmanned aerial vehicles, and more particularly relates to a low-altitude flight altitude determination control system for soft-wing unmanned aerial vehicles. Background technique [0002] At present, drones are used in more and more fields, such as aerial photography, agricultural sowing, emergency communications and material airdrops. However, due to the single function of existing UAVs, many applications are greatly restricted, especially those with strict restrictions on flight height, ground condition perception and location requirements. [0003] In terms of the means of flight altitude measurement, the current commonly used method mainly uses GPS navigation or barometric altimeter to obtain the distance of the unmanned aerial vehicle by obtaining the absolute altitude and the altitude of the aircraft latitude and longitude position on the map. ground height.
