System of recognizing bank paper number in cash-counting machine based on linear array image sensor

The bank paper number synchronous recognized in 1200-rate vertical mode cash-counting machine is realized by 0.1ms/line linear array image sensor and digital signal processor(DSP),and the limited memory of DSP storing large data of the digital image process problem is resolved.The realization of the whole system and cash-counting working at the same velocity,and DSP arithmetic disposing and controlling comes to all at the same time are expatiated.The process of the outcome saving in the flash memory disk by the USB host controller is presented.This system realizes the RMB number gathering dynamically,disposing in-phase,convenient storage.The system reliably runs providing a way to resolve the finance safety matter.
