Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
UAVs face limitations in their working range due to areas with invalid or weak public network signals and high-altitude regions where public networks are difficult to cover, restricting their operation.
Innovation Solution
A network relay method that identifies and establishes communication connections with public networks conforming to preset rules, using a wireless communication module, network interface card, and repeater module to extend network coverage to UAVs, enabling reliable network services in signal-deficient and high-altitude areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If public network is used for UAV control, then communication coverage is limited to areas with valid signal, but expanding to high-altitude and invalid signal areas is needed
Solution Approach 1:
The patent introduces a relay device as an intermediary between the control terminal and UAV. This relay device establishes a first communication connection with the control terminal through public network and a second communication connection with the UAV through wireless communication, enabling UAV control in areas where direct public network coverage is unavailable or unreliable
Solution Approach 2:
The communication path is segmented into two independent connections: a first communication connection between the relay device and control terminal, and a second communication connection between the relay device and UAV. This segmentation allows each connection to be optimized independently, with the relay device bridging the gap between public network coverage and UAV operational areas
2Area of stationary object
If relay device is introduced to expand coverage, then UAV working range is expanded, but system complexity increases
Solution Approach 1:
The relay device is designed with multi-functionality, serving as both a network interface for public network communication and a wireless communication transceiver for UAV communication. This universal design consolidates multiple functions into a single device, reducing overall system complexity despite expanding coverage capabilities
3Reliability
If network evaluation and filtering is implemented, then network connection reliability is improved, but processing time and complexity increase
Solution Approach 1:
The system performs preliminary evaluation of candidate networks before establishing connections. The processor evaluates multiple candidate networks based on preset evaluation criteria and pre-determines the optimal network, so that when connection is needed, the selection has already been made in advance, reducing real-time decision time
Solution Approach 2:
The system implements feedback mechanisms where network evaluation results are used to adjust and optimize future network selections. The processor continuously monitors network conditions and uses feedback from previous evaluations to improve subsequent network selection accuracy and speed
