Fiber Optic Boundary Sensing for Remote Intrusion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barriers at boundaries, such as fences and walls, are ineffective in preventing unauthorized traversal due to remote locations and limited policing resources, allowing intruders to cross undetected and unresponsive.
Innovation Solution
A fiber optic sensor system integrated into a substrate along the boundary, capable of detecting vibrations and generating signals for real-time alerts and responsive actions, such as alarms or drone surveillance, to deter and track intruders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional barriers (fences, walls) are deployed along boundaries, then physical impediment to traversal is provided, but detection and response capability is lost due to remote locations and limited policing resources
Solution Approach 1:
The patent combines the physical barrier function with detection and response functions by integrating sensors, communication devices, and power sources directly into the barrier structure itself, creating a multi-functional system that provides both physical impediment and active monitoring
Solution Approach 2:
The barrier structure is designed to perform multiple functions simultaneously: physical obstruction, vibration detection, alarm signaling, two-way communication, and power supply, eliminating the need for separate detection systems that would be impractical in remote locations
2Length of stationary object
If barriers are deployed in remote areas, then boundary coverage is extended, but detection and response capability deteriorates due to limited policing resources
Solution Approach 1:
The barrier system is self-sufficient in remote locations by incorporating autonomous power sources (solar panels, batteries), onboard sensors for detection, and communication devices for alerting authorities, requiring no external infrastructure or continuous human presence
Solution Approach 2:
The system performs preliminary detection and alerting actions automatically when vibration or intrusion is detected, enabling rapid response before intruders can complete their traversal, and pre-positioning all necessary detection and response components along the boundary
3Ease of manufacture
If simple barrier structures are used, then ease of deployment is improved, but detection precision and response capability deteriorate
Solution Approach 1:
Complex detection and response systems are nested within the simple barrier structure, with sensors, electronics, and power sources integrated into the barrier segments, maintaining the appearance and simplicity of conventional barriers while embedding advanced functionality
Solution Approach 2:
The system uses vibration sensors to detect changes in physical parameters (vibration frequency, amplitude, pattern) caused by intrusion attempts, translating mechanical disturbances into detectable electrical signals for precise intrusion identification

AI summary
Disclosed herein are systems and methods configured to produce and monitor signals that characterize activities corresponding to intruders (e.g., persons and/or animals) traversing a boundary that at least partially defines a designated area. Such activities can characterize one or more persons traversing a boundary or attempting to traverse a barrier that defines the boundary. Sensors within a substrate that extends along the boundary can be used for producing such signals. The substrate can be soil of which ground at the boundary is comprised, a manmade material located within such soil or a material from which a barrier along the boundary is constructed. The sensors can be fiber optic sensors that extend contiguously along a length of the boundary and/or can be fiber optic sensors that are located at discrete locations along the length of the boundary. The signals can cause one or more responsive actions to be implemented.
