Level flight control system and method for fixed-wing unmanned aerial vehicle

Abstract

The invention discloses a level flight control system and method for a fixed-wing unmanned aerial vehicle. The system comprises a flight task control subsystem, an engine adjustment subsystem and an engine detection subsystem. The flight task control subsystem is used for controlling the fixed-wing unmanned aerial vehicle to perform a level flight task when the fixed-wing unmanned aerial vehicle climbs to a preset height value; the engine adjustment subsystem is used for adjusting working parameters of an engine when a level flight task is carried out, so that the working state of the engine is in a cruise state; the engine detection subsystem is used for acquiring state parameters of an engine and judging whether the state parameters meet cruise state standards or not; and the flight task control subsystem is also used for controlling the fixed-wing unmanned aerial vehicle to quit the level flight task when the state parameters do not meet the cruise state standard. The system is used for improving the safety of the fixed-wing unmanned aerial vehicle during level flight.

Description

technical field [0001] The present application relates to the field of unmanned aerial vehicles, in particular to a level flight control system and method of a fixed-wing unmanned aerial vehicle. Background technique [0002] Fixed-wing drones have the characteristics of long battery life and high-altitude flight, and are widely used in border patrol, tactical reconnaissance, public security monitoring, anti-smuggling, anti-drug, disaster monitoring, forest fire prevention, communication relay, meteorological monitoring and geographic information survey and other practical applications. occasion. [0003] In the above actual occasions, especially in geographic information surveys, due to the needs of the surveyed geographic information, it is required to be on the same level, that is, to ensure that the fixed-wing UAVs maintain level flight. [0004] However, the operation of the fixed-wing UAV is very complicated during the level flight mission, and it cannot exit the leve...

AI Technical Summary

Problems solved by technology

[0004] However, during the level flight mission of the fixed-wing UAV, the operating conditions are very complicated, and it is impossible to exit the level flight mission in time, which may cause damage to the fixed-wing UAV, or even crash, causing the fixed-wing unmanned The safety of the aircraft in level flight is not high
