Virtual Tripwire Asset Validation with RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current asset management systems that utilize video surveillance and RFID systems require manual aggregation of video data to detect and rectify asset misdirection in complex conveyance systems, lacking an integrated solution for validating asset movement and requiring additional tools for trend analysis.
Innovation Solution
The implementation of virtual tripwires within the view field of video cameras, coupled with RFID technology, to automatically detect and validate asset movement by defining pathing rules, notifying the asset management system of potential misdirection, and generating suspect movement data for review.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual aggregation of video data is used to detect asset misdirection, then detection capability is provided, but user effort and time consumption increase significantly
Solution Approach 1:
The patent introduces virtual tripwires as intermediary elements that automatically detect asset movement events. Instead of manually reviewing all video feeds, the system places virtual tripwires at critical locations that automatically trigger when assets cross them, providing selective detection without manual intervention.
Solution Approach 2:
The system performs preliminary action by pre-defining virtual tripwires and asset movement specifications before monitoring begins. This allows the system to automatically evaluate asset movements against predefined rules, eliminating the need for manual video review and reducing detection time.
2Loss of information
If video surveillance systems with predefined RFID readers are used, then asset tracking is enabled, but integrated validation of asset movement paths is lacking
Solution Approach 1:
The patent merges video surveillance data with RFID tracking information into a unified asset management system. By combining these data sources and validating them against asset movement specifications, the system provides comprehensive path validation without requiring separate manual processes.
Solution Approach 2:
The system implements feedback by automatically comparing actual asset movements (detected by virtual tripwires and RFID readers) against predefined asset movement specifications. This feedback mechanism provides automatic validation and alerts when deviations occur, eliminating information loss about path compliance.
3Loss of information
If additional tools and systems are used to save and aggregate data for trend analysis, then data availability is improved, but system complexity and operational burden increase
Solution Approach 1:
The patent implements self-service by enabling the asset management system to automatically aggregate, store, and manage suspect movement data without requiring additional external tools. The system performs data aggregation and trend analysis internally, reducing operational burden while maintaining data availability.

AI summary
Validation of asset movement can begin with the definition of a virtual tripwire for video cameras of a video surveillance system that monitor a defined area of interest through which RFID-identified assets are conveyed. The virtual tripwire can visually define a boundary within the view field of the video camera. The video camera can detect the movement of an asset through a virtual tripwire and an asset management system can be notified of the potential misdirection of the asset. The asset management system can obtain the asset's RFID data from a RFID handling system that monitors the area of interest. The validity of the detected movement can be determined using RFID data and an asset movement specification that defines pathing rules for assets and virtual tripwires. When the movement of the asset is determined to be invalid, a record of suspect movement data can be generated for the asset.
