Manual throwing automatic takeoff method for unmanned aerial vehicles

Abstract

The invention discloses a manual throwing automatic takeoff method for unmanned aerial vehicles. The manual throwing automatic takeoff method includes S1, enabling the unmanned aerial vehicles to enter automatic takeoff logics; S2, monitoring trigger action signals of the unmanned aerial vehicles; S3, judging attitude angles of the unmanned aerial vehicles to determine whether the attitude angles are within the ranges of safety unlocking angles or not; S4, unlocking engines and allowing the engines to rotate at full speeds; S5, allowing operators to forwardly manually throw the unmanned aerial vehicles to release the unmanned aerial vehicles; S6, enabling the unmanned aerial vehicles to accumulate airspeeds at the highest speeds and detecting the airspeeds of the unmanned aerial vehicles to determine whether the airspeeds exceed takeoff safety airspeeds or not; S7, confirming climbing altitudes of the unmanned aerial vehicles and keeping the unmanned aerial vehicles to fly along releasing directions; S8, judging whether flight altitudes of the unmanned aerial vehicles reach safety altitudes or not and terminating automatic takeoff procedures if the flight altitudes of the unmanned aerial vehicles reach the safety altitudes. The manual throwing automatic takeoff method has the advantages that dependence on flight controllers and dependence on ground equipment can be lowered in the takeoff procedures of the unmanned aerial vehicles; damage on the air vehicles due to environmental impact or human errors when the air vehicles are taken off can be prevented, and the unmanned aerial vehicles can be assuredly safely taken off.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a hand-throwing automatic take-off method of an unmanned aerial vehicle. Background technique [0002] At present, the take-off method of fixed-wing UAVs is mainly for the pilot to manually control the take-off of the aircraft, and some fixed-wing UAVs also need landing gear or ejection devices to assist the UAV to accumulate airspeed. [0003] This method requires the drone operator to have strong control ability and experience. Especially in the environment of abnormal weather, since people can only judge the flight status of the UAV by the external environment, if the operator makes a wrong operation, it may damage the UAV or even cause harm to the ground personnel. [0004] In terms of take-off aids, whether it is the landing gear or the ejection device, there are strict requirements on the structural strength of the UAV. If the strength is not enough, it is easy to ...

AI Technical Summary

Problems solved by technology

If the strength is not enough, it is easy to cause damage to the drone

And the landing gear needs a relatively long runway, which has special requirements for the take-off site

The ejection rack requires bulky ejection equipment and is relatively poor in portability
