System comprising a drone and an entity for controlling this drone

1. A system comprising a drone having an onboard entity on board said drone and a control entity for controlling the drone and situated remotely from the drone, the control entity being connected to a human-machine interface adapted to enable an operator to select instructions for sending from the control entity to the onboard entity, the onboard entity receiving the instructions sent by the control entity and executing actions corresponding to the instructions received by the onboard entity, wherein:

the onboard entity generates a message from the instructions received by the onboard entity and transmits this message to the control entity; and

the control entity controls warning means to generate an information signal representative of said message transmitted by the onboard entity and received by the control entity;

the system further comprising validation means connected to the control entity, the control entity generating an intention message in response to a command exerted by the operator on said validation means after said information signal has been generated and transmitting said intention message to the onboard entity; and

the onboard entity conditioning the execution of said actions as a function of said intention message, which actions correspond to the instructions previously received by the onboard entity.

2. The system according to claim 1 , wherein the human-machine interface comprises:

selection means selected from hand-controlled selection means and voice-controlled selection means; and

at least one display means for displaying the instructions selected using the human-machine interface; and

the warning means include a loudspeaker for delivering said information signal representative of said message, the information signal then being a signal of audio type, and/or a visual display for displaying the information signal, the information signal then being of text type.

3. The system according to claim 2 , wherein the control entity includes an interpretation device arranged to interpret the message generated by the onboard entity and to deliver a text-type interpreted message to the warning means, said warning means including a voice synthesis device, said information signal representative of the message transmitted by the onboard entity being an audio voice signal synthesized by the voice synthesis device on the basis of said text-type interpreted message.

4. The system according to claim 1 , wherein the instructions selected by the operator are instructions having an influence on a change in the position or the path of the drone or are instructions that are critical for various flight functions of the drone.

5. The system according to claim 1 , wherein the control entity further includes a verification device arranged to verify the digital and semantic integrity of the instructions selected by the operator using the human-machine interface.

6. The system according to claim 1 , wherein the onboard entity further includes a verification device arranged to verify the digital and/or semantic integrity of the instructions received by the onboard entity.

7. The system according to claim 1 , wherein the onboard entity includes storage means for storing the received instructions as sent by the control entity.

8. A method of communication between a control entity for controlling a drone situated remotely from the drone and an onboard entity on board said drone, the control entity being connected to a human-machine interface in order to enable an operator to select instructions for sending from the control entity to the onboard entity, the method comprising:

by the onboard entity, receiving the instructions sent by the control entity;

by the onboard entity, transmitting a message to the control entity, the message being generated from the instructions received by the onboard entity;

by the control entity, controlling warning means to generate an information signal for the attention of the operator, the information signal being representative of said message transmitted by the onboard entity and received by the control entity;

by the control entity, transmitting an intention message to the onboard entity as a function of a command exerted by the operator on said validation means connected to the control entity; and

by the onboard entity, executing said actions that correspond to the instructions previously received by the onboard entity as a function of said intention message.

9. The method of communication according to claim 8 , wherein the human-machine interface includes:

selection means selected from hand-controlled selection means and voice-controlled selection means; and

at least one display means for displaying the instructions selected using the human-machine interface; and

the warning means including a loudspeaker for delivering said information signal for the attention of the operator, the information signal then being a signal of audio type, and/or a visual display for displaying the information signal, the information signal then being of text type.
