Description
技术领域technical field
本发明涉及一种用于检测点钞机对纸币冠字号识别率的方法。The invention relates to a method for detecting the recognition rate of banknote serial numbers by banknote counting machines.
背景技术Background technique
点钞机是一种自动清点钞票数目的机电一体化装置，由于国内现金流通规模庞大，各企事业单位及金融机构现金处理工作繁重，点钞机已成为不可缺少的设备。市面上有一种具备纸币冠字号识别和网络数据传输功能的点钞机，常用于银行点钞/鉴伪。这种点钞机对质量的要求较高，对于市面上流通的纸币（真币、假币以及一些其用于识别/鉴伪的区域遭到污染或破坏的纸币等）需要有较好的识别率，质量差的点钞机经常会出现无法识别或错误识别纸币冠字号的情况，严重影响了点钞机的日常使用需求。因此，针对这种点钞机对纸币冠字号的识别率的检测显得尤为重要。The money counter is a mechatronics device that automatically counts the number of banknotes. Due to the large scale of domestic cash circulation and the heavy cash handling work of various enterprises, institutions and financial institutions, the money counter has become an indispensable equipment. There is a banknote counting machine on the market with banknote serial number recognition and network data transmission functions, which is often used for banknote counting/counterfeiting. This kind of banknote counter has high requirements on quality, and it needs to have a better recognition rate for banknotes circulating on the market (genuine banknotes, counterfeit banknotes, and some banknotes whose identification/authentication areas are polluted or damaged, etc.) However, poor-quality banknote counters often fail to recognize or misidentify banknote serial numbers, which seriously affects the daily use needs of banknote counters. Therefore, it is particularly important to detect the recognition rate of banknote serial numbers for this banknote counting machine.
通常，这种点钞机在出厂时都有专门的人员将点钞机获取的冠字号信息与纸币上的冠字号进行人工比对，然后从中判断出点钞机对纸币冠字号的识别率，这种传统的检测方法效率低下而且容易出错。因此，人们迫切需要一种用于检测这种点钞机对纸币冠字号识别率的方法，以弥足人工检测的不足。Usually, when this banknote counter leaves the factory, special personnel will manually compare the serial number information obtained by the banknote counter with the serial number on the banknote, and then judge the recognition rate of the banknote serial number by the banknote counter. This traditional detection method is inefficient and error-prone. Therefore, people are in urgent need of a method for detecting the serial number recognition rate of banknotes by this money counter, so as to make up for the deficiency of manual detection.
