Banknote Processing Segmentation for Provisional Accounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banknote processing machines face challenges in automatically recognizing and accounting for banknotes from different deposits, leading to high manual processing efforts and incomplete provisional accounting.
Innovation Solution
A method where banknotes are checked using a sensor device and control device, dividing unrecognized banknotes into two groups based on identifiable features, allowing for provisional accounting and assignment to respective accounting units with reduced recognition demands, enabling more complete provisional accounting and reduced manual verification efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If banknotes are automatically recognized and processed by the banknote processing machine, then processing efficiency is improved, but the recognition requirements are high and many banknotes cannot be recognized
Solution Approach 1:
The patent segments the rejection reason into two independent parts: (1) identification feature recognition (serial number) and (2) currency/denomination recognition. By separating these recognition tasks, the system can successfully identify banknotes even when full automatic processing fails, enabling provisional accounting for more banknotes and reducing manual post-processing workload.
2Productivity
If basic recognition of currency and denomination is performed, then provisional accounting can be made, but the recognition demands are relatively high and only a certain proportion of banknotes can be assigned
Solution Approach 1:
The patent applies partial action by performing only the essential identification feature recognition (serial number) rather than complete currency and denomination verification. This partial recognition is sufficient for provisional accounting and assigning banknotes to accounting units, significantly increasing the proportion of banknotes that can be processed while reducing system complexity and post-processing manual effort.
3Measurement precision
If rejected banknotes are manually processed, then complete accounting can be achieved, but the effort required is very expensive
Solution Approach 1:
The patent performs preliminary identification feature recognition and provisional accounting for rejected banknotes before manual post-processing. By pre-identifying serial numbers and provisionally assigning banknotes to accounting units, the system reduces the workload for manual verification to only confirming provisional assignments and handling truly unrecognizable banknotes, significantly reducing manual processing time and costs while maintaining accounting accuracy.

AI summary
A method in which accounting units consisting of one or several bank notes are successively processed by a processing machine, wherein the bank notes are checked by a sensor device and a control device. One or several accounting units are inserted, the information items characterizing the accounting units are entered, the bank notes of each accounting unit are singled, checked, and in dependence on the check are assigned to output units of the processing machine The bank notes recognized upon the check are accounted for the respective accounting unit by the control device and transported into the assigned output unit. Bank notes not recognized upon the check are divided into two groups with a first group containing the unrecognized individual bank notes for which an identification feature characterizing the respective bank note can be ascertained by sensor device and control device, and a second group whose respective identification feature cannot be ascertained by the sensor device and control device.
