Unmanned aerial vehicle control device, unmanned aerial vehicle, unmanned aerial vehicle system and control method

Abstract

The invention discloses an unmanned aerial vehicle control device, an unmanned aerial vehicle, an unmanned aerial vehicle and a control method. The unmanned aerial vehicle control device specificallyincludes a remote controller and a mobile terminal, and the remote controller includes a first 2.4G wireless module and a first processor. The first processor sends a time-stamped control command to the unmanned aerial vehicle by a 2.4GHz wireless network accessed by the first 2.4G wireless module, and the mobile terminal sends a time-stamped control command to the unmanned aerial vehicle througha mobile communication network, so that the unmanned aerial vehicle performs movement based on the latest control commands after performing time stamp comparison of the control commands from the firstprocessor and the mobile terminal with a history control instruction log. The unmanned aerial vehicle control device establishes dual communication links between the control device and the unmanned aerial vehicle, and improves the reliability of the control command and image data transmission.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles. More specifically, it relates to an unmanned aerial vehicle control device, an unmanned aerial vehicle, an unmanned aerial vehicle system and a control method. Background technique [0002] Unmanned Aerial Vehicle (UAV) is an unmanned aircraft controlled by radio remote control equipment and self-contained program control device. It has been developed rapidly because of its advantages of maneuverability, quick response, unmanned flight, and low operation requirements. Civil UAVs can realize real-time image transmission and detection of high-risk areas by carrying a variety of sensors, which is a powerful supplement to satellite remote sensing and traditional aerial remote sensing. At present, it has been widely used in aerial photography, agriculture, plant protection, micro selfie, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, ...

AI Technical Summary

Problems solved by technology

[0004] (1) The control distance of drones is limited: due to the limitation of radio frequency transmission power of ordinary civilian drones, the communication distance ranges from tens of meters to several kilometers, and it needs to be achieved in an open and interference-free environment.

Difficult to meet demand for drones that require remote control

[0005] (2) Low data transmission reliability: A single wireless link is used to communicate between the UAV and the remote control. In the case of interference of the same frequency and the same channel, the control commands and video return will be greatly affected. area, and even only work within a few hundred meters
