Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The logistics industry faces challenges in efficiently managing control channels for unmanned aerial vehicles (UAVs) during take-off and landing due to interference from environmental factors and the high cost of dedicated remote control devices, leading to potential accidents and inefficient frequency spectrum utilization.
Innovation Solution
A control channel allocation method that divides the 2.4G wireless frequency band into 80 control channels, allowing multiple UAVs to share channels at a logistics station, enabling a single remote control device to manage multiple UAVs and rapidly switch between channels, improving frequency spectrum utilization and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated remote control device is provided for each UAV at every logistics station, then control reliability is improved, but device cost and complexity increase significantly
Solution Approach 1:
The patent implements a shared remote control device that can control multiple UAVs through dynamic channel allocation. The flight management server assigns different control channels to different UAVs, allowing a single remote control device to serve multiple aircraft without compromising control reliability. This universal approach eliminates the need for dedicated one-to-one pairing while maintaining safe operation.
Solution Approach 2:
The patent segments the control communication by dividing it into multiple control channels. The flight management server allocates specific channels to different UAVs during critical phases like takeoff and landing, allowing the remote control device to switch between channels to control different UAVs. This segmentation enables one device to manage multiple UAVs simultaneously with proper isolation.
2Productivity
If multiple remote control devices are used simultaneously at the same logistics station, then control capability is improved, but frequency spectrum utilization efficiency deteriorates due to channel interference
Solution Approach 1:
The patent divides the frequency spectrum into multiple control channels and assigns specific channels to different UAVs through the flight management server. This segmentation allows multiple remote control devices to operate simultaneously without interference, as each device communicates on its assigned channel during critical phases, thereby improving both control capability and spectrum efficiency.
Solution Approach 2:
The patent implements dynamic channel allocation where the flight management server assigns control channels based on real-time UAV status and phase of operation. During takeoff and landing, specific channels are allocated; during cruise, other channels may be used. This dynamic approach maximizes frequency spectrum utilization while maintaining control capability.
3Ease of operation
If remote control devices are used in a chaotic manner without systematic allocation, then ease of operation is improved, but safety deteriorates due to inability to accurately interfere with specific UAVs
Solution Approach 1:
The patent implements preliminary action by having the flight management server pre-allocate control channels to UAVs before critical operations like takeoff and landing. The system proactively manages channel assignment and switches, so the remote control device operator simply needs to select the assigned channel to control the specific UAV. This preliminary organization ensures both ease of operation and safety by preventing chaotic control scenarios.

AI summary
A control channel allocation method for a flying device comprises: allocating a task to a flying device, wherein the task comprises flight information for the flying device; determining a flight time of the flying device flying from a departure station to an arrival station according to the flight information; searching for one or more control channels at the departure station and the arrival station that are idle during the flight time based on one or more control channel occupation tables as one or more target control channels, wherein the one or more control channel occupation tables store idle states of a plurality of control channels at the departure station and the arrival station during a plurality of periods of time; and allocating the one or more target control channels for controlling the flying device to fly from the departure station to the arrival station.
