UAV Data Relay via Universal Interface for Real-Time Failure Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) face data transmission delays due to distance, leading to potential loss of control if onboard devices fail, as ground control apparatuses cannot timely receive operating state data, causing unreliable operation or crashes.
Innovation Solution
A method and apparatus for bi-directional data communication between UAVs and ground control apparatuses, using a universal interface to connect various onboard devices, enabling the controller to receive and forward target data, including state data, to ensure timely recognition of device failures and reliable control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If data is transmitted over long transmission distances between ground control apparatus and UAV, then the UAV can operate over larger areas, but data transmission delay increases affecting control reliability
Solution Approach 1:
The patent introduces an onboard device as an intermediary component that collects and processes data locally on the UAV. This intermediary enables real-time data processing and forwarding, reducing the impact of transmission distance delays by handling data locally before transmission to ground control.
2Extent of automation
If onboard devices are equipped with preset operational programs, then the UAV can perform autonomous tasks, but the ground control apparatus cannot obtain real-time operating state data
Solution Approach 1:
The patent implements a feedback mechanism where the onboard device continuously collects operating state data and transmits it back to the ground control apparatus. This feedback loop ensures that ground control receives real-time information about the UAV's operational status, maintaining situational awareness despite autonomous operation.
3Loss of energy
If the ground control apparatus cannot receive real-time state data from onboard devices, then communication bandwidth is reduced, but the UAV may fly blind or crash if the onboard device fails
Solution Approach 1:
The onboard device is designed with self-service capabilities, including local data processing and autonomous operation functions. This allows the UAV to maintain basic operational integrity and safety functions even when communication with ground control is interrupted, reducing the need for constant bandwidth-intensive communication while maintaining reliability.

AI summary
A method for data transmission includes receiving, by a controller of an unmanned aerial vehicle (UAV), target data from a transmitting terminal. The transmitting terminal includes a ground control apparatus or an onboard device of the UAV. The onboard device is connected with the UAV via a universal interface of the UAV. The universal interface is configured to connect onboard devices of various types. The method further includes forwarding the target data to a receiving terminal. The receiving terminal includes the ground control apparatus or the onboard device, and the receiving terminal is different from the transmitting terminal.
