Error correction mechanism and currency counting machine with the same

Abstract

The invention discloses an error correction mechanism for adjusting position of a sheet flexible anti-counterfeiting medium. The error correction mechanism comprises a detection device, a controller and an execution device, wherein the detection device is arranged in a medium channel and used for detecting position information of the medium, wherein position information comprises that whether the medium is strayed and / or whether the interval between neighboring media is in a predetermined range; the controller is used for receiving the position information, and transmitting a control signal according to the position information; and the execution device is used for receiving the control signal and adjusting the position of the medium. The error correction mechanism can adjust the position of each medium to meet the requirements of checking, so as to effectively reduce a rate of error distinguishing and a rate of omitted distinguishing of a sheet flexible anti-counterfeiting medium checking device, effectively improve work efficiency of counting and detecting and reduce work intensity of operators. The invention further provides a currency counting machine comprising the error correction mechanism, wherein the currency counting machine can meet the requirements of new national standard and improve the applicability of the currency counting machine.

Description

technical field [0001] The invention relates to the field of error correction, in particular to an error correction mechanism for thin flexible anti-counterfeiting media. In addition, the present invention also relates to a banknote counter including the above-mentioned error correction mechanism. Background technique [0002] Banknotes are one of the most commonly used examples of thin-sheet flexible anti-counterfeiting media, and are frequently used in modern life. Therefore, equipment applied to thin-sheet flexible anti-counterfeiting media has emerged as the times require. These devices include but are not limited to banknote counting machines, banknote sorting machines, ATM machine, bill identification device, automatic vending machine, automatic ticket vending machine, etc. Taking banknote counting machines as an example, equipment using thin-sheet flexible anti-counterfeiting media is closely related to the work efficiency and quality of people in the industry.

AI Technical Summary

Problems solved by technology

However, in actual work, due to the lack of corners, folded corners, breaks, folds, and inaccurate ways of placing banknotes by operators, banknotes will appear obliquely, double-folded, and consecutive banknotes, which will lead to banknote feature collection. distortion

[0007] When the above banknotes are skewed, the processing method of the banknote counting machine is usually to use the control software to conduct a simple analysis and correction of the collected distortion feature information, and then distinguish it, which cannot restore the authenticity of the banknote features, resulting in misidentification. Leakage is large

It is impossible to meet the requirements of the national standard for missing resolution ≤ 0.015% and false resolution ≤ 0.02%

[0008] And if there are double sheets of banknotes and continuous sheets of banknotes, the existing banknote counters cannot handle at all, and can only report an error and stop. After the operator manually handles the problems of banknotes, the banknote counters can continue to work. The labor intensity of the personnel is high

[0009] Problems like this often appear in banknote counters, and also exist in other equipment using thin flexible anti-counterfeiting media, which affect the work quality and work efficiency of related units
