Supervision and control method for UAV threat avoidance by manned vehicle

Abstract

The present invention provides a supervision and control method for UAV (unmanned aerial vehicle) threat avoidance by a manned vehicle, relating to the field of UAV. According to the method, a supervisory control mode, an environmental factor and threat avoidance action are defined and corresponding values are defined, the inference and judgment of optional threat avoidance actions is carried out, then a final threat avoidance action is judged according to a judgment result, and the threat avoidance is completed. For a known threat, the UAV fully plays independence ability to independently complete threat avoidance or completes operation under the guidance of the manned vehicle. For an unknown threat, the UAV completes avoidance under the guidance of the manned vehicle, and the autonomous execution ability of the UAV and the analysis and judgment ability of a manned vehicle operator are fully played. For an extreme case such as the interruption of communication, the UAV ensures its own safety through adjusting the supervisory control mode. A variable self-supervision and control mode is combined with the characteristics of UAV and the manned vehicle, and the method has good action ability in emergency for different threat types and environmental conditions.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an avoidance judgment method. Background technique [0002] In the face of emergencies, the human-machine operator interacts with the UAV to ensure that the UAV completes the scheduled tasks. Supervisory control refers to manned aircraft interacting with UAVs intermittently, receiving feedback and giving instructions to process control UAVs in the mission environment. [0003] However, in the actual application of UAS threat avoidance, traditional methods generally use manual operations by operators to avoid threats, or use path planning, rules or automatic methods by calculating cost functions (generally taking range and threat as the main factors). Threat avoidance in a machine-based manner. There will be two problems in this way: ①The phenomenon of "overload" caused by too many tasks given to the operator by the complex and changeable environment; ②Because the unmanne...

Problems solved by technology

There will be two problems in this way: ①The phenomenon of "overload" caused by too many tasks given to the operator by the complex and changeable environment; ②Because the unmanned system has too high authority, the operator loses the ability to perceive the overall situation The phenomenon of "Out-of-the-Loop (OOTL)" caused by

The two problems show that the supervision and control of manned and unmanned aerial vehicle threat avoidance needs to be dynamically adjusted according to the actual situation.
