硬币智能识别的软件系统设计.doc

黄石理工学院毕业设计（论文） 摘　　要 硬币在人们的日常生活中扮演着重要角色，同时随着人口的增加和社会文明程度的提高,硬币的需求量会日益增加。硬币代替小面额纸币流通给人们带来许多方便，同时也带来了一些问题。银行等一些特殊部门要对大量的硬币进行高效的处理如计数、分类、包装等以使其再流通，无人售票车、投币电话等需要对硬币进行实时识别，自动售货机除了识别之外，还要提供找零功能等。随着假币的出现，在线识伪也成为了一个急需解决的问题。硬币清分系统应运而生。本文从对硬币进行清分的必要性出发，针对当前国内外硬币清分的现状，提出了一种实用可靠的解决方案。本系统采用 DSP 与单片机构成的主从式系统，实现了对硬币高速、准确地清分。 关键词：硬币清分； DSP；单片机；数据采集；数据处理 Abstract Coins play a very important role in people’s life,and with the increase of the population and the improvement of social civilization,the amount of coins needed will increased greatly.As the substitute of papermoney,coins bring our life much convenience,and many problems as well.Some special departments,such as banks, for example,counting the numbers of coins,dividing coins and packaging coins.Automatic ticket cars,public telephones,etc,which need coins,must discern coins in-time,and charging.Furthermore,with the appearing of fake coins,the task of discerning fake coins in-time becomes an urgent problem.And then the coins counting and discerning system comes into existence. The article put forward a practical and reliable project for coins counting and discerning system at the base of essentiality of coins counting and discerning,and aiming at the current situation of coins counting and discerning in the world.The system,arguing in the article,adopts the multi-CPU system composed of DSP and MPU,and realizes coins counting and discerning with high speed and high accuracy.
