Problems solved by technology

The traditional emergency treatment method for measurement and control failures is to align the unmanned helicopter to the take-off point and return home autonomously. However, in the face of different task importance and different flight stages in the route, the priority between flight platform safety and task execution may need to be dyn

Example Embodiment

[0033]The design method involved in the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034]An emergency handling method for link failure during flight of unmanned helicopter routes, providing three optional modes:

[0035]1) Return to home mode on the original route, that is, during automatic route flight, when the measurement and control link fails, the helicopter will immediately adjust the course and fly back to the take-off point along the flight route.

[0036]2) Direct return mode, that is, during automatic route flight, when the measurement and control link fails, the helicopter will immediately exit the route flight and adjust the heading to return to the take-off point with the shortest straight path.

[0037]3) Mission priority mode, that is, during automatic route flight, when the measurement and control link fails, the helicopter continues to fly on the current automatic route without handling.

[0038]1. Return to home mo...

Abstract

The invention belongs to the technical field of flight control of unmanned helicopters, and discloses a link failure emergency disposal method during route flight of an unmanned helicopter. Three selectable modes are provided: an original route return mode, namely, during automatic route flight, when a measurement and control link fails, the helicopter immediately adjusts the heading direction toreversely fly along the covered route to return to a take-off point; a direct course reversal mode, namely, during automatic route flight, when a measurement and control link fails, the helicopter immediately exits the route flight, and adjusts the heading direction to return to a take-off point through a shortest straight line path; a task priority mode, namely, during automatic route flight, thehelicopter continues the current automatic route flight and does not deal with the situation that the measurement and control link fails.

Description

technical field [0001] The invention belongs to the technical field of unmanned helicopter flight control, and in particular relates to an emergency treatment method for link failure during flight of an unmanned helicopter. Background technique [0002] The unmanned helicopter system consists of an unmanned helicopter and a ground station, and the operator of the ground station monitors and commands the whole process of the unmanned helicopter. Route flight is the autonomous flight of unmanned helicopters according to pre-booked routes, which is the most important way to perform tasks. When flying on the route, the measurement and control link may be interrupted. At this time, the ground station loses control of the unmanned helicopter, and the unmanned helicopter needs to fly fully autonomously. The traditional emergency treatment method for measurement and control failures is to align the unmanned helicopter to the take-off point and return home autonomously. However, in ...
