In-flight auto-ignition control method of engine of unmanned aerial vehicle

Abstract

The invention discloses an in-flight auto-ignition control method of an engine of an unmanned aerial vehicle. The method comprises: (11), detecting whether a ground control station is out of control, or whether the engine of the aerial vehicle is subjected to accidental flameout and shut down; (12), if the ground control station is out of airplane control ability, or the engine of the aerial vehicle is subjected to accidental flameout and shut down, executing the step (13); (13), detecting whether the communication link between the unmanned aerial vehicle and the ground control station is normal, if the communication link between the unmanned aerial vehicle and the ground control station is normal, executing the step (14); (14), detecting whether the engine working condition information and the aerial vehicle flight state meet operation requirements, if the engine working condition information and the aerial vehicle flight state meet the operation requirements, executing the step (15); and (15), detecting whether a throttle servo, an accelerator servo and a task servo of the engine can work normally, if the throttle servo, the accelerator servo and the task servo of the engine can work normally, carrying out an ignition command, and restarting the engine; if the throttle servo, the accelerator servo and the task servo of the engine cannot work normally, stopping sending the ignition command. The method can be applied to reignition and starting of the unmanned aerial vehicle after fault recovery, the aerial vehicle can be effectively protected, and the flight cost is reduced.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a control method for automatic ignition of an unmanned aerial vehicle engine in the air Background technique [0002] An unmanned aerial vehicle is an unmanned aerial vehicle controlled by radio remote control equipment and its own program control device, such as an unmanned aircraft. Unmanned aerial vehicles can generally be divided into unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned parawing aircraft, etc. The application range of unmanned aerial vehicles is more and more extensive, including in aerial photography, agriculture, plant protection, selfie, express transportation, disaster rescue, observation of wild animals, monitoring of infectious diseases, surveying and mapping, news reports, power inspection, disaster relief, film and television shooting, manuf...

Problems solved by technology

[0006] However, this solution is only applicable to restarting the aeroengine after it is accidentally turned off when the aircraft’s operating conditions are all normal. Its working logic is to turn off and start immediately. Whether the condition of the failure is eliminated or whether the working condition of the aircraft is suitable for re-ignition start, that is, the above scheme cannot adapt to the start-up control of the re-ignition of the unmanned aircraft after the failure
