Banknote Counting IC Tag Mediator for Detection Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper stock processing systems, such as banknote processing devices, face inaccuracies in detecting when the paper stock stored in a container reaches its limit due to factors like wrinkles and stains on banknotes and variations in thickness.
Innovation Solution
A paper stock processing system that includes a paper stock processing device with an accommodation unit, a storage unit for accumulating paper stock information, a control unit to update the count, and a transmitter to send signals to an external apparatus via a mediation device, allowing for precise detection of the paper stock limit through comparison with a set maximum number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the number of banknotes is approximated by measuring the thickness of the wad of banknotes, then the detection process is simple, but misdetection occurs due to wrinkles, stains, and thickness variations
Solution Approach 1:
An IC tag is introduced as an intermediary storage device attached to the container. This IC tag stores the accumulated number of banknotes accommodated in the container, serving as a reliable mediator between the physical banknotes and the detection system, eliminating the need for thickness measurement while ensuring accurate detection.
2Adaptability or versatility
If communication data is limited to standardized industry protocols, then communication compatibility is improved, but the ability to transmit detailed paper stock information is reduced
Solution Approach 1:
The accumulated number of banknotes is preliminarily stored in the IC tag attached to the container before any communication occurs. This preliminary storage action ensures that complete and accurate information is prepared in advance, allowing the system to transmit detailed paper stock information through standardized protocols without losing any critical data.

AI summary
It is possible to accurately detect that paper stock stored in a container reaches a limit number. A paper stock processing system includes: a banknote processing device which includes a banknote accommodation unit accommodating banknotes, updates the accumulated number each time a banknote is accommodated, and transmits an updated accumulated number signal; a smart interface board which transmits the accumulated number signal to the outside when receiving the accumulated number signal; and a management server which compares the accumulated number indicated by the accumulated number signal with the maximum number and detects whether the number of accommodated banknotes has reached a limitation number set to the banknote accommodation unit 100, when receiving the accumulated number signal from a PTS terminal.
