Fault monitoring system and method for flight control execution mechanism of flying wing unmanned aerial vehicle

Abstract

The invention discloses a fault monitoring system and method for a flight control execution mechanism of a flying wing unmanned aerial vehicle. The fault monitoring system comprises a fault detectionsystem, a flight computer, a plurality of execution structures and a flight attitude response sensing system. The fault detection system sends a fault detection instruction; an action signal is sent to the execution mechanism after processing by the flight computer; the flight attitude data of a wing unmanned aerial vehicle during flight are collected and the collected data are transmitted to thefault detection system; and thus motion state of the execution mechanism is determined to complete fault monitoring of the execution structures. Various instructions and signals are transmitted through the communication bus, so that the real-time performance of data communication is good; a redundant structure is easy to form; and the reliability and flexibility of the system are improved.

Description

technical field [0001] The invention belongs to the field of fault monitoring of flying-wing unmanned aerial vehicles, and in particular relates to a fault monitoring system and method of a flight control executive mechanism of flying-wing unmanned aerial vehicles. Background technique [0002] UAVs have become the most popular use and research direction in today's society, and they play a very important role in both civil and national defense. With the development of social technology, the structure of flying-wing UAVs is becoming more and more complicated but reliable. The demand for sex is getting higher and higher. The flight control system is the central brain of the drone. Once the flight control system fails, it may lead to unimaginable accidents. [0003] The UAV flight actuator controls the flight attitude of the UAV and is an important part of maintaining the accuracy of flight control. Conventional layout drones generally include wings, fuselage, and empennage. ...
