Method and device for processing interruption of remote control link of unmanned aerial vehicle and unmanned aerial vehicle

Abstract

The invention provides a method and device for processing interruption of a remote control link of an unmanned aerial vehicle and a unmanned aerial vehicle. The method comprises the steps: starting timing when the unmanned aerial vehicle enters an interruption waiting state, and judging whether the link interruption of the unmanned aerial vehicle is caused by an interference signal; if so, judging whether a remote control link data signal is detected or not when the timing duration is smaller than or equal to the interference judgment preset duration T5; if so, continuing to execute the flight task , and if not, executing link interruption difficult-to-recover processing, wherein the interference judgment preset duration T5 is larger than the interruption difficult-to-recover judgment preset duration T2. According to the method and device, the judgment of the interference signal is added in the link interruption judgment of the unmanned aerial vehicle, and if the link interruption is judged to be caused by the interference signal, the state of the unmanned aerial vehicle is converted into an interference waiting state instead of entering an interruption difficult-to-recover state, so that the unmanned aerial vehicle is prevented from giving up an original task due to recoverable interference; and the task completion rate and the actual combat performance of the aircraft are greatly improved.

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.
