Solution Overview

Problem

Conventional FPV flight systems for unmanned aerial vehicles (UAVs) experience delays and inaccuracies due to the need for a remote controller to relay image and control signals, leading to safety hazards.

Innovation Solution

The system establishes direct channels between smart glasses and the UAV for image data and between the remote controller and the UAV for control instructions, eliminating the need for signal relaying and enabling real-time, accurate control.

1Reliability

If a remote controller is used to relay image signals and control signals between the UAV and smart glasses, then the system can achieve FPV flight control, but signal transmission delays and control inaccuracies occur

Engineering Contradiction:

Improvecontrol accuracyVSAvoidsignal transmission delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the image transmission function from the remote controller and creates a separate direct communication channel between the UAV and smart glasses. This separation eliminates the relaying delay where the remote controller had to receive and retransmit signals, allowing image data to flow directly from the UAV camera to the glasses while control signals use a dedicated channel from the remote controller to the UAV.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The communication system is segmented into two independent channels: one for image transmission (UAV to smart glasses) and another for control transmission (remote controller to UAV). This segmentation allows each channel to operate optimally without interference, with the image channel providing real-time visual feedback and the control channel ensuring precise command execution, thereby resolving the contradiction between speed and accuracy.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a remote controller relays signals, then the system structure is simple to implement, but control safety and responsiveness are compromised

Engineering Contradiction:

Improveflight safetyVSAvoidcommunication channel structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces a direct communication link as an intermediary channel between the UAV and smart glasses, bypassing the remote controller for image transmission. This intermediary pathway ensures that visual feedback reaches the pilot without delay, improving flight safety and responsiveness, while the remote controller maintains its role as the sole intermediary for control commands, preserving system manageability.

AI summary

A system for controlling an unmanned aerial vehicle (UAV) includes smart glasses and a remote controller. The smart glasses are configured to establish a first channel directly with the UAV, receive first person view (FPV) image data directly from the UAV through the first channel, and display the FPV image data. The remote controller is configured to establish a second channel directly with the UAV, and send a flight control instruction directly to the UAV through the second channel.
