Processing method and device for unmanned aerial vehicle remote control link interruption, and unmanned aerial vehicle

Abstract

The invention provides a processing method, device and unmanned aerial vehicle for the interruption of the remote control link of the unmanned aerial vehicle. Caused by an interference signal; if it is caused by an interference signal, it is judged whether the remote control link data signal is detected when the timing duration is less than or equal to the interference judgment preset duration T5; if yes, continue to perform the flight mission, otherwise, execute the link Interrupt refractory processing, wherein, the preset time period T5 for judging interference is longer than the preset time period T2 for judging whether it is refractory to interrupt. In the present invention, by adding the judgment of the interference signal in the link interruption judgment of the UAV, if it is judged that the link interruption is caused by the interference signal, the state of the UAV is turned into an interference waiting state instead of entering an interruption difficult state. It can prevent the UAV from abandoning the original mission due to recoverable interference, which greatly improves the mission completion rate and practicality of the aircraft.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a processing method and device for interrupting a remote control link of an unmanned aerial vehicle, and an unmanned aerial vehicle. Background technique [0002] The radio measurement and control system of the UAV is usually the UAV data link system; it can be divided into uplink and downlink according to the direction of data transmission. The uplink mainly completes the sending and receiving of remote control commands from the ground station to the UAV, which is generally called the remote control link; the downlink mainly completes the sending and receiving of telemetry data, infrared or TV images from the UAV to the ground terminal As well as the transmission of tracking and positioning information, it is also generally called a telemetry link. If the remote control link is interrupted, that is, the remote control command cannot be sent to the drone. At this time, th...

Problems solved by technology

However, in the above-mentioned related technologies, if the remote control link data signal is still not received for the preset time period T2 after continuous interruption, the link status will be changed to "interruption and recovery", without considering whether there are other factors that cause the link to be interrupted If the occurrence of the problem occurs, it will directly enter the interrupted and unrecoverable state, deal with the unrecoverable link interruption, and abandon the original mission. The lack of practicality will greatly reduce the completion rate of aircraft missions.
