UAV Battery Protection Using Position-Based Safety Energy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric unmanned aerial vehicles (UAVs) lack an intelligent method to manage battery electricity effectively, leading to accidents due to insufficient power and inefficient battery utilization, especially when flying to remote positions.
Innovation Solution
An intelligent method for managing electricity in electric UAVs, which involves real-time monitoring of battery remaining electricity and the UAV's position, calculates the safety electricity amount needed for specific commands, and automatically performs safety protection commands if the remaining electricity is insufficient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fixed reference voltage value alarms are used, then the alarm system is simple to implement, but the UAV cannot receive alarms when flying to remote positions and may crash or return early
Solution Approach 1:
The system pre-calculates and stores the relationship between position coordinates and required electricity amounts for safety commands (return to home, land, etc.). When the UAV flies to remote positions, the system can proactively determine the electricity needed for safe return or landing before the battery is depleted, preventing crashes and unnecessary early returns.
Solution Approach 2:
The system continuously monitors the UAV's real-time position coordinates and compares the current remaining electricity with the pre-calculated safety electricity amount at that position. This dynamic feedback mechanism adjusts alarm triggers based on actual position and battery status, enabling intelligent decision-making for return or landing commands at appropriate moments.
2Reliability
If real-time position monitoring and dynamic electricity calculation are implemented, then the UAV can receive intelligent alarms and avoid crashes, but the system complexity increases
Solution Approach 1:
The system pre-calculates and stores the relationship between position coordinates and required electricity amounts for safety commands (return to home, land, etc.). When the UAV flies to remote positions, the system can proactively determine the electricity needed for safe return or landing before the battery is depleted, preventing crashes and unnecessary early returns.
Solution Approach 2:
The system continuously monitors the UAV's real-time position coordinates and compares the current remaining electricity with the pre-calculated safety electricity amount at that position. This dynamic feedback mechanism adjusts alarm triggers based on actual position and battery status, enabling intelligent decision-making for return or landing commands at appropriate moments.

If fixed voltage threshold alarms are used, then the alarm system is simple, but battery utilization is reduced due to early returns or landings
Solution Approach 1:
The system pre-calculates and stores the relationship between position coordinates and required electricity amounts for safety commands (return to home, land, etc.). When the UAV flies to remote positions, the system can proactively determine the electricity needed for safe return or landing before the battery is depleted, preventing crashes and unnecessary early returns.

AI summary
An aerial vehicle includes a position sensor configured to obtain a present position of the aerial vehicle and a controller. The controller is configured to calculate, based on the present position and a preset position specified by a user, safety energy information of the aerial vehicle, and control, based on the safety energy information, the aerial vehicle to perform a safety protection command.
