Banknote processing device

Abstract

The invention discloses a banknote processing device, including a control part, a storage part, an operation part, a transportation part, a reading part, a judging part and an identifying part which are connected through a bus. The reading part reads banknote characteristic quantities and depreciation state; the storage part stores three sets of banknote characteristic quantity reference information of different threshold ranges, each set includes a plurality of characteristic quantity reference parameters, and each reference parameter has a corresponding threshold maximum value and minimum value; the judging part calls the banknote depreciation state, and comprehensively calculates the banknote depreciation degree; the identifying part calls the characteristic quantity reference information of the corresponding level according to the banknote depreciation degree, and compares each characteristic quantity of a banknote with the corresponding threshold range, and if all the characteristic quantities are located in the corresponding threshold range, the banknote is identified as a genuine banknote; and the control part controls working states of all components. The technical scheme improves precision of identifying authenticity of banknotes, and avoids the problem that possibility of mistakenly identifying forged banknotes, incomplete banknotes and stained banknotes as genuine banknotes becomes high.

Description

technical field [0001] The invention relates to the technical field of paper processing equipment, in particular to a banknote processing device. Background technique [0002] Conventionally, there is known a sheet discriminating device that discriminates the authenticity of a sheet based on the characteristics of the sheet. In the sheet discriminating device, the maximum value and the minimum value of the feature quantity for discriminating authenticity are set in advance, and the range from the maximum value to the minimum value is set as a reference threshold value. And, when the characteristic amount of the paper sheet is within the range of the threshold value, the paper sheet is judged as genuine, and when the characteristic amount of the paper sheet is outside the range of the threshold value, the paper sheet is judged as fake. coupon. [0003] In such a method of judging the authenticity of paper sheets, it is necessary to take into account unevenness in printing a...

Problems solved by technology

Therefore, there is a problem that although the stored unique information can be used for processing the counterfeit bill, it cannot be used for discriminating counterfeit bills having the same characteristic information.

[0006] This patent can use the preserved inherent information to discriminate counterfeit coupons with the same characteristic information, but it still fails to increase the identification accuracy for counterfeit coins, incomplete coins, and defaced coins, and fails to propose a general The way the threshold range is set for
