Alert Device for Unpermitted Flying Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively issue alerts for unexpected flying objects entering regions where work is being performed, such as disaster sites.
Innovation Solution
An alert device that uses sensors to determine the position of a flying object and checks for a specific signal pattern associated with permitted missions within a predetermined region. If no signal is detected, the device identifies the flying object as unpermitted and uses a light projection device to irradiate its position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing control and management systems are used for flying objects, then flying objects can be controlled and managed, but it is not possible to issue an alert identifying unexpected flying objects entering restricted regions
Solution Approach 1:
The system segments the monitoring function into distinct components: position determination unit for location tracking, signal reception unit for communication signal detection, and alert generation unit for warning issuance. This segmentation enables specialized detection of unauthorized flying objects while maintaining overall system reliability.
Solution Approach 2:
The alert device acts as an intermediary between the flying object management system and personnel in restricted regions. It receives position information and communication signals, processes this data to identify unauthorized objects, and generates alerts for personnel, thereby filling the information gap without requiring changes to existing management systems.
2Ease of operation
If a light projection device is used to alert personnel about unpermitted flying objects, then alert effectiveness is improved, but device complexity increases
Solution Approach 1:
The system merges multiple functions into a single integrated alert device: position determination, signal reception and analysis, permission verification, and light-based alert generation. This consolidation improves ease of operation by providing comprehensive monitoring and alerting in one device while managing complexity through functional integration rather than separate systems.
Solution Approach 2:
The system replaces complex mechanical or manual alerting methods with optical signaling using light projection devices. This substitution enhances alert effectiveness by providing visible, immediate warnings to personnel while reducing the complexity associated with mechanical alarm systems or manual notification procedures.

AI summary
An alert device according to an aspect of the present disclosure includes: at least one memory storing a set of instructions; and at least one processor configured to execute the set of instructions to: identify, from measurement data of a flying object by a sensor, a position of the flying object; determine whether the flying object is located within a predetermined region; determine whether a signal of a predetermined pattern assigned to a mission in the predetermined region is received from the flying object determined to be located within the predetermined region; determine, in a case where no signal of the predetermined pattern is received from the flying object, that the flying object is an unpermitted flying object that is not permitted to enter the predetermined region; and cause a light projection device to irradiate a position of the unpermitted flying object with light.
