摘要
介绍了一种基于DSP(数字信号处理器)的CCD(电荷耦合器件)图像处理系统的设计方法,采用线阵CCDTCD142D与TI公司的TMS320F2812DSPDSP和89C52单片机结合设计了一种图像处理系统。介绍了系统硬件设计和软件设计,阐述了线阵CCDTCD142D的工作原理和该系统的工作原理。DSP对数据进行处理,然后通过单片机控制点钞机的外设,来实现点钞机的智能清分点钞,纸币鉴伪,挑残以及面值识别等功能。
This paper introduces a design of CCD （Charge Coupled Device） image processing system based on DSP （Digital Signal Processor）TMS320F2812 which is produced by TI Company, combined with linear CCDTCD142D and singlechip89C52. The design of hardware and software of this system is described and the working principles of the CCDTCD142D and the whole system are illustrated. Through the DSP processing the data and then 89C52 controlling the peripheral equipments of banknotes dynamic discriminating device, the system realizes the intelligent functions to distinguish different kinds of paper money, to identify the fake or broken money and to recognize the par value of different money.
