Banknote Recognition Control for Dispensing Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of banknote dispensing systems decreases due to unstable recognition results, where a banknote recognized as normal may be re-recognized as abnormal in subsequent dispensing processes, leading to reduced dispensing efficiency.
Innovation Solution
A banknote processing apparatus and method that includes a recognition unit, transport unit, and control unit to manage banknotes by storing abnormal notes in a temporary storage unit and re-evaluating them, with predetermined conditions determining whether to return them to the main storage or a secondary storage unit to maintain dispensing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If banknotes are re-recognized after being stacked in the temporary storage unit, then abnormal banknotes can be identified and separated, but recognition results become unstable and banknotes may be repeatedly misrecognized as abnormal
Solution Approach 1:
The system performs preliminary actions by storing recognition results and banknote information in memory before final dispensing decisions are made. This allows the system to reference previous recognition outcomes and avoid redundant re-recognition of the same banknotes, thereby stabilizing recognition results while maintaining dispensing efficiency.
Solution Approach 2:
The system implements feedback mechanisms by comparing current recognition results with previously stored recognition data. When a banknote is re-recognized, the system references its recognition history to determine whether to trust the new result or maintain the previous classification, thus preventing unstable fluctuation between normal and abnormal classifications.
2Measurement precision
If banknotes with unstable recognition results are repeatedly re-recognized, then recognition accuracy may improve, but dispensing time increases and efficiency decreases
Solution Approach 1:
The system performs preliminary storage of recognition results and banknote identification information in memory before final dispensing. This preliminary action allows rapid retrieval of recognition data without requiring time-consuming re-recognition processes, thereby maintaining high recognition accuracy while minimizing dispensing time.
Solution Approach 2:
Instead of completely re-recognizing banknotes that were previously classified as abnormal, the system performs partial verification by comparing current recognition data with stored historical data. This partial action approach maintains recognition accuracy while significantly reducing the time required compared to full re-recognition.
3Reliability
If all banknotes are subjected to multiple recognition processes, then recognition reliability improves, but the complexity of the processing system increases
Solution Approach 1:
The system segments the recognition process into distinct phases: initial recognition, result storage, and conditional re-recognition. By dividing the processing into manageable segments with clear decision points, the system maintains high recognition reliability through multiple checks while avoiding the complexity of continuous, unconditional re-recognition of all banknotes.
Solution Approach 2:
The system applies different recognition strategies to different banknotes based on their specific characteristics and recognition history. Banknotes with stable recognition results undergo minimal processing, while only those with uncertain or conflicting results undergo additional verification, thereby maintaining reliability without uniformly increasing system complexity across all banknotes.

AI summary
Provided is a sheet processing apparatus including a control unit that causes storage control processing to be performed. The storage control processing is processing in which a sheet stored in a temporary storage unit is transported to a first storage unit or a second storage unit. The storage control processing includes: first processing in which, in a case where a predetermined condition is satisfied, the sheet stored in the temporary storage unit is transported to the second storage unit; and second processing in which, in a case where the predetermined condition is not satisfied, the recognition unit performs second recognition processing on the sheet stored in the temporary storage unit, the sheet recognized as normal is transported to the first storage unit, and the sheet recognized as abnormal is transported to the second storage unit.
