Solution Overview
Problem
Existing systems for protecting industrial facilities from objects like birds, drones, and animals are complex, costly, and inefficient due to the need for numerous high-resolution cameras and varied deterrent signals, often causing environmental disturbances.
Innovation Solution
A defense system comprising distributed camera units and signal transmission units, a computing unit, and applications for object recognition, classification, and signal assignment, allowing precise detection and targeted deterrents based on object type and position, reducing the number of high-resolution cameras and optimizing signal intensity and type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of high-resolution cameras are used to accurately detect objects, then detection precision is improved, but device complexity and cost increase
Solution Approach 1:
The surveillance area is divided into multiple zones, each monitored by a single standard-resolution camera. Objects in different zones are detected independently, allowing the use of multiple lower-resolution cameras instead of fewer high-resolution ones, thereby reducing overall system complexity and cost while maintaining detection capability
Solution Approach 2:
The system transitions from using spatial resolution (camera megapixels) as the primary dimension for detection accuracy to using temporal processing (frame rate analysis) and zonal segmentation as additional dimensions. This allows standard-resolution cameras to achieve effective detection precision through intelligent image processing and multi-zone monitoring
2Reliability
If varied deterrent signals are used to effectively repel different objects, then defense effectiveness is improved, but environmental disturbance increases
Solution Approach 1:
Different types of objects detected in different surveillance zones are responded to with specifically tailored deterrent signals appropriate to each zone and object type. This localized approach ensures effective defense against each object while minimizing unnecessary environmental disturbance in areas where deterrents are not required
Solution Approach 2:
The system dynamically adjusts the parameters of deterrent signals (type, intensity, frequency) based on the detected object's characteristics and location. By changing signal parameters rather than using fixed high-intensity signals, the system achieves effective repulsion while reducing overall environmental impact
3Measurement precision
If multiple cameras are used to determine object position and flight path, then measurement precision is improved, but the number of required cameras increases
Solution Approach 1:
The surveillance area is segmented into multiple zones, each monitored by a single camera. Object position and flight path within each zone are determined using algorithms that analyze sequential frames from that one camera, eliminating the need for multiple cameras per zone while maintaining measurement precision through temporal analysis
