Fault handling method and device for avionics electrical system of a fixed-wing unmanned aerial vehicle

Abstract

The present application discloses a fault handling method and device for the avionics system of a fixed-wing unmanned aerial vehicle. The method includes: identifying the current flight stage of the fixed-wing unmanned aerial vehicle; The operating data of the avionics electrical system of the man-machine; according to the operating data of the avionics electrical system and the preset fault criterion rules, analyze and obtain the fault type of the avionics electrical system of the fixed-wing unmanned aerial vehicle; according to the current flight stage, the type of failure of the avionics electrical system, and the preset failure handling rules to handle the failure of the fixed-wing UAV. For fixed-wing UAVs in different flight stages, logically analyze the types of avionics electrical system failures, and deal with different avionics electrical system failures to reduce the risk of power failure of fixed-wing UAV equipment and reduce the risk of fixed-wing UAV equipment failure. The control law of wing UAV solves the impact, so as to ensure flight safety.

Description

technical field [0001] The present application relates to the field of unmanned aerial vehicles, and in particular, to a fault handling method and device for an avionics electrical system of a fixed-wing unmanned aerial vehicle. Background technique [0002] With the development of my country's social economy, the field of drones has also developed rapidly. It can not only be used in urban management, agricultural insurance work, logistics industry, electric power inspection, emergency rescue and disaster relief, video shooting and other industries, but also in modern warfare. Complete battlefield reconnaissance and surveillance, positioning and calibration, electronic stations, etc., and are widely used. [0003] The application of UAVs is becoming more and more extensive, which puts forward higher requirements for the safe flight of UAVs. During the flight, if the avionics electrical system fails, the UAV equipment will lose power and cannot work normally. , the solution o...

Problems solved by technology

[0003] UAVs are more and more widely used, which puts forward higher requirements for the safe flight of UAVs. During the flight, if the avionics electrical system fails, it will cause the UAV equipment to lose power and fail to work normally. , the solution of the control law of the UAV is affected, the aircraft cannot fly normally, causing a flight accident, and in serious cases, a crash may occur, causing property damage and casualties

However, in the existing technology, it is impossible to flexibly deal with the faults of different avionics and electrical systems of fixed-wing UAVs in different flight states, resulting in low flight safety and low efficiency of flight mission execution
