Money counting machine solution based on CIS sensor

A money counting machine is a device that automatically counts banknotes. As the scale of cash circulation becomes larger and larger, the level of counterfeit banknote manufacturing is getting higher and higher, requiring banknote counting machines to integrate counting and counterfeit identification, and continuously improving the counterfeit detection performance of banknote counting machines. According to the new regulations issued by GB16999-2010 "General Technical Conditions for RMB Discriminators", the new national mandatory standard for banknote counting machines has added the counterfeiting level indicator of RMB discriminators. For the first time, banknote counting machines are divided into 3 different levels, namely A There are three grades, B and C. Among them, Class A and B are the bank currency counting and inspection machine grades, and Class C is the commercial currency counting and inspection machine grade. Class A banknote counting machines must have more than 9 identification capabilities/identification technologies.

This reference design provides a banknote counting machine solution based on CIS sensors, which can implement identification technologies such as white light image analysis, infrared light image analysis, edge image processing (with related algorithms, serial number recognition can be achieved).
The DSP uses the ADSP-BF609 Blackfin processor, which is optimized for embedded vision and video analysis applications, using a dual-core fixed-point DSP processor and a unique Pipeline Vision Processor (PVP), designed to speed up image processing algorithms and reduce overall bandwidth requirements And design.
CIS analog front end: The high-speed design uses ADDI7006, which can provide 6 channels of 10-bit analog-to-digital conversion, up to 40MSPS per channel; the low-speed design uses AD9826/AD9822, which can provide 3 channels of 16-bit analog-to-digital conversion, up to 5MSPS per channel.
