Perimeter Security Sensor Threat Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing perimeter security systems often dispatch personnel to investigate non-threatening events, wasting time and resources due to inaccurate threat evaluation at central control systems, which can be flawed by faulty sensors and are resource-intensive in large-scale environments.
Innovation Solution
Implementing a perimeter security system where sensors monitor and process event signals locally to determine threats, generating a confirmation request and message only if the event is deemed a threat, allowing for more accurate and efficient evaluation before alerting personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If threat evaluation is performed at the central control system, then personnel dispatch accuracy is improved, but system resource consumption increases
Solution Approach 1:
The patent divides the threat evaluation function into two segments: initial evaluation at the sensor level and confirmation evaluation at the central control system. This segmentation allows most events to be filtered locally, reducing the burden on central resources while maintaining accurate threat assessment through hierarchical processing.
Solution Approach 2:
The sensor performs preliminary threat evaluation before transmitting data to the central control system. This preliminary action filters out non-threatening events early in the process, so that only events requiring further investigation are transmitted, thereby reducing overall system resource consumption while maintaining evaluation accuracy.
2Reliability
If personnel are dispatched to investigate all events, then threat detection completeness is improved, but time and resource efficiency deteriorates
Solution Approach 1:
The system implements a feedback mechanism where sensors continuously monitor events and automatically evaluate them against threat criteria. Only events that meet specific threat thresholds trigger personnel dispatch, creating a feedback loop that maintains detection completeness while eliminating unnecessary responses to non-threatening events.
Solution Approach 2:
The sensor system performs self-service by automatically evaluating events and determining whether personnel dispatch is necessary. This self-service capability filters out benign events like animals or weather conditions, ensuring that personnel are only dispatched to genuine threats, thus maintaining reliability while reducing time loss.
3Device complexity
If a single sensor evaluates threats, then system complexity is reduced, but measurement accuracy deteriorates
Solution Approach 1:
The evaluation system is segmented into multiple levels: individual sensors perform initial evaluation, and the central control system performs confirmation evaluation. This segmentation allows each component to have a simple, dedicated function while the collective system achieves high accuracy through hierarchical verification.
Solution Approach 2:
The central control system acts as an intermediary that receives and confirms threat evaluations from sensors. This intermediary layer provides a second layer of verification, improving measurement precision by cross-checking sensor evaluations without requiring each sensor to be overly complex.

AI summary
A method of operating a perimeter security system comprises monitoring a perimeter for a plurality of events, receiving an event signal for an event of the plurality of events wherein the event signal comprises an acceleration, processing the first event signal to determine if the event is a threat, transferring a confirmation request to confirm that the event is a threat in response to determining that the event is a threat, receiving a confirmation response in response to the confirmation request confirming that the event is a threat, and generating and transmitting a message identifying the event in response to confirming the threat.
