Development Of The Control And Processing System For Currency Sorter

With the increase in the quantity and circulation velocity of money, Currency Sorter is becoming more and more important. Currency Sorter is a kind of financial equipment with classification function, which can identify and classify currency characteristics including denomination, orientation,anti-counterfeiting features and so on. Sorter uses electromechanical integration structure and artificial intelligence technology, making note management efficiency greatly improved.Currency Sorter, as a kind of intelligent electromechanical equipment, can't do well without display device, motors and all kinds of sensors. at the same time, the currency image is the most important reference for sorting, so image recognition of high real-time and accuracy is indispensable.Dual-processor architecture is a good idea for the sorter system, one processor is used for overall control and user interaction, the other is used for digital signal processing. By means of some interface, the communication and synchronization between processors are implemented. And the combination of single-chip microcomputer and DSP (Digital Signal Processor) is a nice choice.Briefly, the system development contains the following aspects: (1) hardware system development, involving the embedded system architecture and interface; (2) software system development, involving design of software workflow and realization of user interaction; (3) recognition algorithm, involving an overview of currency image recognition algorithm.
