Bandwidth-adaptive unmanned aerial vehicle remote control method

Abstract

The invention discloses a bandwidth-adaptive unmanned aerial vehicle remote control method which comprises the steps of detecting an effective packet rate of a communication link between a remote control device and an unmanned aerial vehicle, and performing data communication on the communication link between the remote control device and the unmanned aerial vehicle at a first bandwidth; judging whether the effective packet rate is within a preset value range of the effective packet rate corresponding to the first bandwidth or not; if the effective packet rate is not within a preset value range of the effective packet rate corresponding to the first bandwidth, the bandwidth of the remote control device and the bandwidth of the unmanned aerial vehicle are adjusted to be a second bandwidth so that a communication link between the remote control device and the unmanned aerial vehicle performs data communication with the second bandwidth; and the remote control device and the unmanned aerial vehicle adjust the transmission data volume according to the second bandwidth. Compared with an existing unmanned aerial vehicle remote control method adopting fixed bandwidth for communication, the unmanned aerial vehicle remote control method has the advantages that the bandwidth can be dynamically adjusted, the balance between the communication data volume and the communication distance canbe better considered, and unmanned aerial vehicle remote control is more intelligent.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an adaptive bandwidth remote control method for unmanned aerial vehicles. Background technique [0002] Under the existing technology, the wireless radio frequency bandwidth of the UAV remote control is fixed, and the remote control data, UAV data transmission data, and image transmission data that can be transmitted are also fixed. If a lower bandwidth is selected, when the UAV is close to the remote control and the signal is strong, there will be a problem of poor user experience due to the long response delay of the operation of the UAV, and the transmission cannot meet the needs of video transmission. Data volume; if a higher bandwidth is selected, due to the negative correlation between the remote control distance of the UAV and the RF communication bandwidth, when the UAV is far away from the remote control and the signal is weak, the UAV will lose control ...

Problems solved by technology

If a lower bandwidth is selected, when the UAV is close to the remote control and the signal is strong, there will be a problem of poor user experience due to the long response delay of the operation of the UAV, and the transmission cannot meet the needs of video transmission. Data volume; if a higher bandwidth is selected, due to the negative correlation between the remote control distance of the UAV and the RF communication bandwidth, when the UAV is far away from the remote control and the signal is weak, the UAV will lose control and cause the communication distance to change. short question

[0003] Therefore, the current UAV remote control method has the disadvantage of not being able to take into account the amount of communication data and the communication distance at the same time due to the use of fixed bandwidth for communication.
