Paper currency sorting device and control method thereof

Abstract

The invention relates to a financial device used for paper currency sorting, in particular to a paper currency sorting device and a control method thereof. The invention has the advantages that the structural design is simple, the maintenance of a sorter is easy, the acquisition speed of the sorter can be adjusted in time in the process of sorting paper currency to adapt to the requirement of keeping high image resolution during the high-speed paper currency processing of the sorter, the extraction of the characteristic zones of paper currency is realized, the sorter has the functions of outputting currency, denomination, surface condition, integrity condition, numbers, infrared fluorescence color-changing ink and other anti-counterfeit features of paper currency, the speed is high, the performance is stable, the counterfeit identification accuracy is high, the resolution of the numbers and the images of paper currency can reach above 200DPIx200DPI at the paper currency processing speed of 600 pieces / minutes, and the image resolution requirement of an OCR under the condition of 99 percent of accuracy is satisfied.

Description

technical field [0001] The invention relates to a financial device applied to banknote sorting, in particular to a banknote sorting device and a control method thereof. Background technique [0002] The new national standard discussion draft for banknote counters proposes that future banknote processing financial equipment needs to have image recognition functions, and have the function of outputting banknote currency, denomination, orientation, completeness, number, infrared and other anti-counterfeiting features. [0003] Among the banknote processing financial equipment currently on the market, most banknote sorting machines have a hinged currency pressing device or banknote pressing system. The banknote transmission structure is relatively complicated, and the volume is relatively large, which takes up a lot of space and is difficult to maintain. , and the configuration of the counterfeit identification system and mechanical components is not integrated and reasonable en...

Problems solved by technology

[0005] However, during the operation of the banknote sorting machine, the banknote import motor or banknote transmission motor that drives the banknotes has high speed. The image scanning equipment of the identification system generally uses a contact image scanner. If the banknote import motor or banknote transmission The operation control of the motor is poor, and the contact image scanner cannot capture the banknote number characters and image performance well. The image acquisition and recognition of banknotes must meet the high resolution of the image during the high-speed processing of banknotes.
