Embodiment Construction

[0032] In order to solve the problem that the UAV aircraft engine is stopped in the air, out of control and unable to stop for protection, the UAV engine failure processing method of the present invention includes a control computer system with data acquisition and signal processing, and in the control computer Configure system fault automatic diagnosis module and fault handling logic program module. The program module used for engine speed monitoring and UAV emergency recovery by using functional devices such as parachute control and buffer airbag / bracket is based on the engine fault automatic diagnosis and fault handling control logic program module of the control computer system. It mainly includes:

[0033] (1) "Signal Acquisition Program Module" for extracting engine speed sensor signal (including: components such as "Optical Interval", "A / D Acquisition", "Event Manager Capture");

[0034] (2) Real-time monitoring of ignition device voltage and frequency program modules ...

Abstract

The invention relates to an engine failure treating method for an unmanned aerial vehicle. The engine failure treating method comprises a control computer system, a logic program module, a signal collecting element, a signal collecting program module, and a program module, wherein the control computer system is provided with the functions of data collecting and signal processing; the logic program module is arranged in a control computer and can automatically diagnose, control and process system failure; the signal collecting element and the signal collecting program module are used for extracting a rotate speed sensor signal of an engine and monitoring the voltage and the pulse frequency of an ignitor in real time; and the program module is used for an engine cylinder temperature sensor and is used for monitoring and judging whether cylinder score failure exists or not. According to the method, an accident failure emergency control function for an engine is merged into a failure diagnose unit of the control computer system, an emergency return journey program module comprising a guided system and a control unit for opening a parachute and an air bag, releasing a buffer bracket and the like, thus the engine failure situation can be monitored in real time and can be processed in emergency, the treating method disclosed by the invention is safe and effective, the failure can be monitored in real time and can be automatically diagnosed and processed, the dead problem due to the engine failure is solved, and the method has the advantages that the response is quick, the success rate is high, and the reliability is high.

Description

technical field [0001] The invention relates to a method for processing the aircraft with a flight control computer system when the engine of the drone fails. Background technique [0002] UAV is a kind of unmanned aerial vehicle that carries few sensors, cannot troubleshoot itself, and has poor autonomous control ability. Its control is much more complicated than manned combat aircraft to a large extent. The engine is the heart of the aircraft, and it is also the main component that is prone to failure. Once the engine fails, the chances of a crash are very high. Common causes of UAV engine failure mainly include: [0003] Engine shutdown failure: engine temperature is too high and the cylinder is pulled, engine ignition system failure, fuel supply failure, engine shutdown and shutdown, these failures are a very fatal accident that directly leads to the loss of power of the aircraft, and the aircraft stalls and crashes; [0004] Engine out of control failure: mainly incl...
