Solution Overview
Problem
Existing gunshot location systems face challenges in accurately detecting and locating weapons fire in complex and noisy acoustic environments, particularly in transportation centers like airports, where sensors are often uniformly distributed and fail to optimize detection accuracy for various attack scenarios.
Innovation Solution
The strategic placement of acoustic sensors in non-regularly spaced patterns along travel paths and around sub-regions, combined with processing components that utilize relative arrival times and angles of detection, allows for precise location determination of weapon firing incidents, including muzzle and mortar explosions, and the passage of bullets or rockets, enhancing detection accuracy and reducing sensor density requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If sensors are uniformly distributed in the region, then coverage area is maximized, but detection accuracy for weapon firing incidents deteriorates due to inability to optimize for various attack scenarios
Solution Approach 1:
The patent applies local quality by transitioning from uniform sensor distribution to non-uniform placement patterns. Sensors are strategically positioned with varying densities in different sub-regions and along travel paths based on specific detection needs. This allows the system to optimize detection accuracy for weapon firing incidents in critical areas while maintaining adequate coverage across the entire region, resolving the contradiction between coverage area and detection accuracy.
2Measurement precision
If sensor density is increased to improve detection accuracy, then detection precision improves, but system complexity and cost increase
Solution Approach 1:
Instead of uniformly increasing sensor density across the entire region, the patent applies local quality by concentrating sensors in specific sub-regions and along travel paths where weapon firing detection is most critical. This strategic localization achieves high detection accuracy in priority areas without proportionally increasing overall system complexity and cost.
Solution Approach 2:
The patent segments the monitoring region into multiple sub-regions with different sensor densities and characteristics. Each sub-region is optimized for its specific detection requirements, allowing the system to achieve high overall detection accuracy without requiring uniformly high sensor density everywhere, thus reducing total system complexity.
3Measurement precision
If sensors are placed along travel paths and in sub-regions with non-regular spacing, then detection accuracy for weapon fire improves, but sensor arrangement complexity increases
Solution Approach 1:
The patent applies local quality by implementing different sensor spacing patterns in different locations: non-regular spacing along travel paths for detecting moving targets and different patterns in stationary sub-regions. This location-specific optimization improves location determination accuracy for weapon fire while managing arrangement complexity through systematic regional differentiation.
