A Redundancy Management Method Applied to Human Intervention of Unmanned Aerial Vehicles

Abstract

The invention discloses a redundancy management method applied to manual intervention of an unmanned aerial vehicle, and belongs to the field of flight control of unmanned aerial vehicles. The redundancy management method particularly comprises the following steps: firstly, selecting parts in dual-redundancy configuration and the redundancy management method for the manual intervention for a certain unmanned aerial vehicle system; then increasing a manual intervention instruction, and determining manual intervention principles and a manual intervention program; finally, combing the manual intervention instruction for the parts in dual-redundancy configuration to realize the redundancy management method for the manual intervention; the manual intervention is combined with automatic system redundancy management, so that certain parts with self-detection functions can provide artificial judgments and set fault channels for operating personnel under the conditions that data of the parts are abnormal, but faults of the parts are not reported to improve the flight safety; on the other hand, through the manual intervention, data of spare parts are observed in a telemetry interface of a ground station to provide the channels for early detection of the abnormal data of the spare parts and realize early detection of hidden dangers so as to improve the flight safety.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle flight control, and specifically refers to a method for managing redundancy of manual intervention applied to unmanned aerial vehicles. Background technique [0002] With the increasing number of flight functions of UAVs, the mission requirements become more and more complex, which makes the flight control system more and more complicated, resulting in higher and higher frequency of failures. In order to improve mission reliability, researchers usually use The importance of UAV system components is comprehensively analyzed and designed with redundant configuration. [0003] Redundancy configuration design puts forward requirements for redundancy management technology accordingly. The purpose of redundancy management design is to maximize the reliability of mission completion and flight safety, so that the system can operate efficiently during normal work. System performance degradation is m...

[0017] The hidden danger of this compromise solution is: the data information of the main component is abnormal or invalid, but the failure is not reported, and the operation of the redundancy management will not automatically switch to the backup component, so the system still uses the abnormal or invalid data, which will be very dangerous, while the spare parts with normal data are not used, resulting in a waste of resources
