Drone Detection Device Using Radio Frequency Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drone detection methods are unreliable, expensive, and lack real-time notification capabilities, failing to provide a simple and cost-effective way for individuals to detect unmanned aerial drones in their proximity, which is crucial for privacy and security concerns.
Innovation Solution
A low-cost, standalone device equipped with a System on Chip (SOC) and WiFi/Bluetooth radio that receives and recognizes remote identification messages from drones, alerting users through visual, audible, or vibration indicators, and can be worn or carried, with adjustable settings for signal strength and alert duration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior art drone detection methods are used, then detection capability is provided, but reliability is poor and cost is high
Solution Approach 1:
The patent replaces complex mechanical or electronic beacon systems with a radio frequency-based detection approach using a radio receiver and antenna to capture drone identification broadcasts. This substitution enables reliable detection while significantly reducing manufacturing complexity and cost, as the system uses standard radio communication components rather than specialized detection hardware.
2Measurement precision
If complex detection systems are implemented, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The patent extracts only the essential function needed for drone detection - receiving and processing identification broadcast messages - while eliminating unnecessary complex components. The system uses a simple processor to decode radio messages and basic indicators (visual/audible) to alert users, achieving accurate drone identification without complex sensor arrays or processing systems.
Solution Approach 2:
The patent employs a universal radio receiver that can detect drones using standard radio frequency communication protocols. This multi-functional approach allows the same device to receive identification messages from various drone types and communicate with remote devices through WiFi/Bluetooth, reducing overall system complexity while maintaining detection accuracy across different scenarios.
3Reliability
If real-time drone detection is implemented, then privacy protection is enhanced, but energy consumption increases
Solution Approach 1:
The patent implements periodic scanning of radio frequencies for drone identification messages rather than continuous monitoring. The processor periodically activates the radio receiver to listen for broadcast messages, then enters a low-power state when no drones are detected. This periodic operation maintains real-time detection capability while significantly reducing average power consumption compared to continuous monitoring systems.
Data Source
AI summary
A drone detection apparatus and method for same, that provides a real time solution for detecting drones and informing and alerting a user. The apparatus includes a housing with a processor and memory, at least one indicator, at least one switch, a connector, a radio, an antenna and a power source; and a housing-carrier in which the housing is removably secured. When a drone transmits an identification broadcast message the processor has the ability to receive and recognize the identification broadcast message. The apparatus can receive a remote identification message intermittently broadcast from a drone and can send, forward and receive alerts to and from one or more remote devices.
