UAV Power Management for Imaging Payload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicles (UAVs) face challenges in minimizing power consumption during travel, especially when equipped with imaging devices, which can lead to insufficient power reserves to reach a target position.
Innovation Solution
The implementation of a system within the UAV that includes a processor and memory for estimating power consumption and controlling power usage by adjusting the imaging device's mode based on remaining power, providing notifications to switch to a recommended power-saving mode or stop the imaging process when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the imaging device operates continuously during travel, then imaging functionality is maintained, but power consumption increases and may prevent reaching the target position
Solution Approach 1:
The imaging device operates dynamically - switching between active imaging mode and power-saving mode based on real-time power status. The control unit monitors remaining power and estimates power consumption to determine when to adjust imaging operations, making the system adaptive rather than static.
Solution Approach 2:
The system implements feedback control by continuously monitoring remaining power levels and estimated power consumption, then using this information to control the imaging device's operation. The control unit provides notifications to the user based on power status, creating a closed-loop system that adjusts behavior based on power availability.
2Adaptability or versatility
If the imaging device is equipped on the UAV, then imaging capability is provided, but power consumption increases
Solution Approach 1:
The system applies partial action by operating the imaging device only when necessary and at reduced power consumption levels when power is limited. Instead of continuous full-power operation, the system uses power-saving modes that provide sufficient imaging capability while consuming less energy, applying just enough action to meet the mission requirements.

AI summary
An unmanned aerial vehicle traveling with an imaging device includes at least one memory and at least one processor which function as: an estimation unit configured to estimate an amount of power consumed by the imaging device and the unmanned aerial vehicle during a time period in which the imaging device and the unmanned aerial vehicle travel from a current location to a target position; and a control unit configured to execute control to give a predetermined notification based on a remaining amount of power of a power supply unit configured to supply power to the imaging device and the unmanned aerial vehicle, and an amount of power consumption estimated by the estimation unit.
