UAV Flight Route Display for Sundown Time Restriction Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicle (UAV) systems lack the capability to autonomously plan and display flight routes that adhere to time zone restrictions, specifically preventing flight after sundown, which is a regulatory requirement in many areas.
Innovation Solution
A method and system that accepts input for a departure point and waypoints, displaying a flight route that includes an end time arrival point within a permitted time zone, allowing users to set routes that ensure the UAV returns before flight restrictions end, and preventing flight beyond permitted hours by distinguishing between flyable and non-flyable routes visually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UAV autonomously flies along a predetermined flight route without time zone consideration, then the flight operation is simple and efficient, but the UAV may fly after the end time of permitted time zone, violating regulatory requirements
Solution Approach 1:
The system performs preliminary calculation of the end time arrival point before the UAV executes the flight route. By computing where the UAV will be at the end time and displaying this information to the user in advance, the system enables proactive adjustment of the flight route to ensure compliance with time zone restrictions, rather than reacting after a violation occurs.
2Reliability
If the system displays detailed flight route information including end time arrival point, then compliance with flight restrictions is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it calculates the end time arrival point, generates visual representations of the flight route, displays information to the user, and controls the UAV's autonomous flight. By consolidating these functions into a single control unit, the system achieves compliance monitoring without proportionally increasing overall system complexity.
3Ease of operation
If the UAV autonomously plans flight routes without user input, then ease of operation is improved, but the ability to ensure compliance with time zone restrictions worsens
Solution Approach 1:
The system provides feedback to the user by displaying the calculated end time arrival point and the segment of the flight route that extends beyond the end time. This feedback loop allows the user to understand the compliance status of the autonomously planned route and make informed adjustments to ensure the UAV returns before the end time of the permitted time zone.

AI summary
A flight route control method of an unmanned aerial vehicle includes: accepting, by an input, an input of a departure point and a waypoint that the unmanned aerial vehicle will pass; receiving a predetermined time, indicating an end of a time period in which the unmanned aerial vehicle is permitted to fly; generating a flight route passing through the departure point and the waypoint; determining whether or not an arrival time to the waypoint is later than the predetermined time; not accepting the waypoint for the generated flight route when the arrival time is later than the predetermined time; accepting the waypoint for the generated flight route when the arrival time is not later than the predetermined time; and transmitting a control command to the unmanned aerial vehicle, the control command controlling the unmanned aerial vehicle to fly according to the generated flight route.
