UAV Flight Route Display for Time-Restricted Autonomous Missions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unmanned aerial vehicles 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 allow users to input departure points and waypoints, displaying flight routes that respect time zone permissions, including an end time arrival point, to ensure the UAV returns before flight restrictions are violated, using a terminal and server configuration that generates and displays flight routes in different modes to distinguish permissible and non-permissible flight segments.
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 zones, violating regulatory requirements
Solution Approach 1:
The system performs preliminary calculation of the end time arrival point before the UAV executes the flight route. The flight management device calculates where the UAV will be at the end time of the permitted time zone based on the current position, speed, and planned route, then displays this information to the user in advance, allowing preventive adjustment of the flight route to ensure compliance.
2Reliability
If the system displays detailed flight route information including end time arrival point, then regulatory compliance is ensured, but the device complexity increases
Solution Approach 1:
The flight management device acts as an intermediary between the UAV's autonomous flight system and the user. It receives the current position and speed from the UAV, calculates the end time arrival point, and presents this information through a display interface. This intermediary layer handles the complexity of time zone compliance calculations while maintaining a relatively simple user interface.
3Reliability
If the UAV returns to departure point by end time of permitted time zone, then regulatory compliance is achieved, but the flight duration is limited
Solution Approach 1:
The system calculates the end time arrival point in advance based on the current flight plan and UAV speed. By displaying this information before the flight concludes, users can proactively adjust the route or speed to ensure the UAV returns by the end time, maximizing the usable flight duration within regulatory constraints rather than discovering compliance issues after the fact.

AI summary
A flight route control method of an unmanned aerial vehicle includes: accepting, by a touch panel, 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.
