Embodiment 1

[0050] Such as figure 1 As shown, the UAV remote control system is built: the UAV remote control system includes a client, a cloud server, a ground control station and multiple UAVs; the UAV is equipped with an onboard computer and controller, and the onboard computer and UAV controllers communicate through the CAN bus; the client, cloud server, ground control station, UAV onboard computer and controller are all equipped with 4G wireless communication modules, while the ground control station, UAV onboard Both the computer and the controller are equipped with a wireless image transmission module and a data transmission module; the client and the cloud server communicate through a 4G wireless communication module; the user registers an account through the ground control station, and each account is bound to one or more An unmanned aerial vehicle; according to the above-mentioned unmanned aerial vehicle remote control system, three ways of remote control of the unmanned aerial v...

Embodiment 2

[0065] Before the UAV takes off, the user selects one of the control methods as the setting mode through the user terminal, and controls the UAV to fly according to the setting mode. When the UAV is flying at a high altitude, the stability of direct 4G communication between the cloud server and the UAV controller is poor, and the communication of the currently selected mode is interrupted, but the 4G communication between the cloud server and the ground control station is effective. , and the image transmission communication between the ground station and the onboard computer of the UAV is valid, and at the same time, the CAN bus communication between the onboard computer and the controller is valid, select the following control mode to remotely control the UAV, such as Figure 4 Shown:

[0066] 1), the user sends the flight control command through the user terminal, and encodes the flight control command, and transmits the encoded data packet to the cloud server through the 4...

Embodiment 3

[0074] When the flying height of the UAV is low, the cloud server and the UAV controller can communicate directly through 4G to realize precise control of the UAV. Then select the following control mode to remotely control the UAV, such as Figure 5 Shown:

[0075] 1), the user sends the flight control command through the user terminal, and encodes the flight control command, and transmits the encoded data packet to the cloud server through the 4G wireless communication module;

[0076] 2) After the cloud server receives the command data packet, it decodes it and performs an authentication operation to judge the binding relationship between the user and the target UAV device and the correctness of the command;

[0077] 3) After the authentication is passed, the cloud server remotely transmits the flight instruction data to the on-board computer of the drone bound to the account through the 4G wireless communication module; the controller;

[0078] 5) The on-board computer of...

Abstract

The invention discloses a cloud-based UAV remote multi-path combined control method, including 1), building a UAV remote control system: the UAV remote control system includes a client, a cloud server, a ground control station and multiple UAV; 2) Before the UAV takes off, the user selects one of the control methods as the setting mode through the user terminal, and controls the flight of the UAV according to the setting mode. During the flight of the UAV, the currently selected When the fixed mode fails, the UAV remote control system automatically judges which of the other two control methods is available, and switches to the available control method to control the UAV to continue flying. With the help of 4G communication and cloud controller, remote control of drones is realized, thereby overcoming geographical and distance limitations. And switch the optimized control mode to provide a variety of solutions, so as to meet the different application requirements and scenarios of different users, and ensure the reliability and stability of the control.

Description

technical field [0001] The invention belongs to the field of remote control of unmanned aerial vehicles, and in particular relates to a cloud-based remote multi-channel combination and an optional stable control method, thereby realizing diverse control of unmanned aerial vehicles. Background technique [0002] As the technology of drones becomes more and more mature, the application fields of drones are becoming more and more extensive. Man-machine, aerial photography UAV, reconnaissance UAV, etc. [0003] At present, UAV control mostly uses a combination of remote control, image transmission and data transmission to achieve short-distance control, mostly several kilometers, and it is difficult to realize long-distance and free coordinated control of multiple UAVs, which in turn limits the performance of UAVs. ; and very few systems that use remote control technology, due to the single control method and path, it is difficult to match the different application requirements...
