UAV Flight Restriction Control Based on Battery and Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned aerial vehicles (UAVs) often operate without considering various factors that affect their performance, leading to potential loss of control or crashes due to mismatches between permitted and capable operations, particularly regarding energy sources and environmental conditions.
Innovation Solution
A system that uses processors to receive and process parameters related to UAV operations, including battery state and environmental conditions, to dynamically impose restrictions on UAV operations, ensuring safe and efficient flight by matching internal states with permitted operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UAV operations are permitted without monitoring internal state parameters, then operational flexibility and ease of operation are improved, but reliability deteriorates due to potential loss of control or crashes from over-discharging
Solution Approach 1:
The system continuously monitors internal state parameters (battery voltage, temperature, motor current) and provides feedback to dynamically adjust operational restrictions. When parameters indicate deteriorating conditions, the system automatically imposes restrictions to prevent unsafe operations, thus maintaining reliability while allowing flexible operation under safe conditions.
Solution Approach 2:
The operational restrictions are not static but dynamically adjusted based on real-time internal state parameters. The system transitions between different operational modes (unrestricted, restricted, emergency) depending on the current state, allowing maximum flexibility when conditions are good while ensuring safety when conditions deteriorate.
2Reliability
If operational restrictions are imposed based on internal state parameters, then reliability is improved by preventing unsafe operations, but device complexity increases due to monitoring and processing requirements
Solution Approach 1:
The processor performs multiple functions: it controls flight operations, monitors internal state parameters, determines operational restrictions, and manages emergency procedures. By making the processor multi-functional, the patent avoids adding separate dedicated hardware for each function, thus improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The system combines parameter monitoring, state determination, and restriction enforcement into a single integrated control process. Rather than separate systems for monitoring battery voltage, temperature, and motor current, all these functions are merged into one unified control architecture that processes multiple parameters simultaneously to determine appropriate operational restrictions.
3Measurement precision
If environmental conditions are monitored as proxy for internal state, then measurement precision is improved for certain parameters, but loss of information increases due to indirect measurement
Solution Approach 1:
The system performs preliminary direct measurement of critical internal state parameters (battery voltage, temperature, motor current) before relying on environmental condition proxies. This ensures accurate baseline information is obtained directly, while environmental monitoring serves as supplementary verification and extends monitoring capability to parameters that are difficult to measure directly.

AI summary
A system for operating a vehicle includes a first temperature sensor located at a first location and configured to measure a first temperature; a second temperature sensor located at a second location configured to measure a second temperature; and one or more processors. The one or more processors are individually or collectively configured to receive information regarding the first temperature and/or the second temperature; process the information; and impose a restriction affecting operation of the vehicle based on the processed information.
