Drone Collision Avoidance System Using Image Detection and Signal Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack the capability to effectively prevent or restrict unmanned aerial vehicles (UAVs) from entering restricted airspace, posing a collision risk to piloted aircraft, especially at low altitudes where distractions and dangers can compromise safe flight.
Innovation Solution
A Drone Collision Avoidance System (DCAS) that includes a system processor, image-detecting elements, and a transmitter to detect and disrupt the operation of UAVs, alerting pilots to potential collisions and enabling evasive maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no detection system is installed, then the device complexity is low, but the safety and collision avoidance capability deteriorates
Solution Approach 1:
The detection system is divided into separate functional modules: image-detecting element for capturing visual data, image processing unit for analyzing frames and detecting UAVs, and transmitter for sending disruption signals. This segmentation allows each component to be optimized independently while maintaining overall system reliability for collision avoidance.
Solution Approach 2:
The system performs preliminary detection of UAVs in the flight path before a collision can occur. The image processing unit continuously analyzes captured frames to identify potential threats, allowing the pilot to take evasive maneuvers in advance, thereby improving safety proactively rather than reactively.
2Measurement precision
If image processing is performed on every frame, then the detection precision improves, but the processing time and computational load increases
Solution Approach 1:
The image processing unit performs processing on a selected subset of captured frames rather than every single frame. This partial action approach maintains sufficient detection precision by analyzing key frames that are most likely to contain UAVs, while significantly reducing the computational time and processing load compared to analyzing every frame continuously.
3Reliability
If a transmitter is used to disrupt UAV operation, then the collision avoidance effectiveness improves, but the device complexity and potential interference with other systems increases
Solution Approach 1:
The transmitter acts as an intermediary component that sends disruption signals to UAVs detected in the flight path. This intermediary approach improves collision avoidance effectiveness by actively interfering with UAV operation, while the modular design keeps the added device complexity manageable and contained within a specific functional unit.

AI summary
An automatic system to detect and avoid collisions between piloted aircraft operating at low altitudes and unmanned aerial vehicles (UAV). UAV's are typically remote controlled helicopters, quad-copters, airplanes and other airborne vehicles (e.g., Drones). Aircraft operating at low altitudes are subject to interference (accidental or purposefully) by those on the ground operating said UAV's, which is likely to cause great injury or death to the aircraft and its occupants.
