Adaptive Position Transmission Interval for Flying Vehicle Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for tracking the position of a flying vehicle, such as drones, fail to transmit position information effectively when the vehicle crashes in areas with damaged communication equipment or where communication is not possible, making it difficult to recover the vehicle with precision.
Innovation Solution
A system comprising a positioning unit, specification unit, determination unit, and sending unit that measures and transmits the flying vehicle's position during flight, specifies ground features, determines optimal transmission intervals based on these features, and sends position information accordingly to facilitate recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If position information is transmitted only after the flying vehicle has fallen to the ground, then energy consumption is reduced, but the position cannot be transmitted when communication apparatus is damaged or in regions where communication is not possible
Solution Approach 1:
The patent applies dynamics by making the position information transmission adaptive rather than static. The transmission interval is dynamically adjusted based on the flying vehicle's state (flying vs. fallen) and ground surface features. When the vehicle is flying, position is transmitted at one interval, and when fallen, the transmission behavior changes based on whether the ground surface allows for successful transmission attempts, thereby optimizing energy consumption while maintaining reliability.
Solution Approach 2:
The patent changes the transmission parameter (transmission interval) based on different conditions. By detecting ground surface features after impact, the system determines whether to continue transmission attempts or stop, effectively changing the transmission parameter from continuous to conditional. This resolves the contradiction by allowing energy-efficient operation when communication is possible while maintaining reliability when communication fails.
2Measurement precision
If position information is transmitted continuously during flight, then the position can be grasped with high precision, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by transmitting position information at specific intervals during flight rather than continuously. The system transmits position data at predetermined intervals when the vehicle is airborne, maintaining adequate position tracking precision while reducing energy consumption compared to continuous transmission.
Solution Approach 2:
The transmission strategy dynamically switches based on the vehicle's flight state. During flight, periodic transmission maintains position precision awareness. After impact detection, the system transitions to a different transmission mode based on ground surface analysis, optimizing energy usage while preserving necessary position information for recovery operations.
3Loss of energy
If the sending interval is extended to conserve energy, then energy consumption is reduced, but the position precision deteriorates
Solution Approach 1:
The patent applies local quality by differentiating transmission strategies based on the local condition (ground surface features) detected after impact. Rather than using a uniform transmission interval, the system analyzes specific ground characteristics at the impact location and adjusts transmission behavior accordingly, allowing extended intervals in favorable conditions while maintaining precision where needed.
Solution Approach 2:
The system changes transmission parameters based on detected ground surface features. By analyzing the local environment after impact, the system determines whether to extend transmission intervals for energy conservation or maintain shorter intervals for precision, effectively adapting the parameter to local conditions rather than applying a fixed approach.

AI summary
Recovery of a flying vehicle that has fallen to the ground is facilitated. A positioning unit measures a position of the flying vehicle during flight. A specification unit specifies a feature of a region on the ground corresponding to the measured position. A determination unit determines a sending interval of position information indicating the position of the flying vehicle, according to the specified feature. A sending unit sends the position information at the determined sending interval.
