下面结合附图描述本实用新型的实施例，其中：Describe embodiments of the present utility model below in conjunction with accompanying drawing, wherein:

图1是本实用新型纸币鉴别器的结构立体分解示意图；Fig. 1 is the three-dimensional exploded schematic diagram of the structure of the banknote validator of the present invention;

图2是本实用新型纸币鉴别器的工作流程图。Fig. 2 is a working flow chart of the banknote validator of the present invention.

现今市面上流通量大的几种纸币，其共同的防伪特性为：The common anti-counterfeiting characteristics of several banknotes with large circulation in the market today are:

1、双面对印1. Double-sided printing

2、浮水人像2. Floating portrait

3、金属防伪线3. Metal anti-counterfeiting thread

其他特性为纸币的颜色各不相同，且均为凹板印刷。Other characteristics are that the banknotes vary in color and are all intaglio printed.

根据上述的特性，本实用新型鉴别纸币的方式为：According to above-mentioned characteristic, the mode that the utility model distinguishes banknote is:

1、依纸币颜色及纸币尺寸来区分纸币的币值。1. Distinguish the currency value of banknotes according to the color and size of banknotes.

2、依纸币的颜色、金属防伪线、双面对印的精确度及纸币尺寸等条件来鉴别纸币的真伪。2. Identify the authenticity of banknotes according to the color of banknotes, metal anti-counterfeiting thread, accuracy of double-sided printing and banknote size.

上述鉴别方式的原理为：The principle of the above identification method is:

1、利用颜色来鉴别币值：以能识别颜色的扫描器对大量的纸币中间文字币额的部分加以扫描，以取得作为对比基础的资料，再将此资料存于记忆体中；使待鉴别的纸币中间文字币额的部分经扫描器扫描，以取得该纸币币额的颜色资料，再与记忆体中的资料对比，相同则判定该纸币符合一项识别标准，不相同则判定为无法识别（非判定其为伪钞）。同时，由颜色上亦辨别出该纸币的币值。1. Use color to identify currency value: use a scanner that can recognize the color to scan the part of the middle text of a large number of banknotes to obtain data as a basis for comparison, and then store this data in the memory; make the to-be-identified The part of the text in the middle of the banknote is scanned by the scanner to obtain the color data of the banknote, and then compared with the data in the memory. If it is the same, it will be judged that the banknote meets a recognition standard. If it is not the same, it will be judged as unrecognizable ( It is not determined that it is a counterfeit banknote). At the same time, the currency value of the banknote can also be distinguished from the color.

2、利用金属防伪线鉴别：以检测器测定纸币上是否有金属防伪线，同时判断其位置是否正确，再有防伪线上下两端对应纸钞边缘是否平行，及防伪线的宽度是否正确，与记忆体中所采集的大量经验资料对比，作为第二项识别标准。2. Identification by metal anti-counterfeiting thread: Use detectors to determine whether there is a metal anti-counterfeiting thread on banknotes, and at the same time judge whether its position is correct, and whether the upper and lower ends of the anti-counterfeiting thread correspond to the edges of banknotes are parallel, and whether the width of the anti-counterfeiting thread is correct. The comparison of a large amount of experience data collected in the memory is used as the second identification standard.

3、利用双面对印精确度鉴别：由于纸币采用双面对印方式印制，而非一面印好再印另一面，故纸币正反面的花纹图案存在着一定的相对关系；以能识别颜色的扫描器对待测纸币左右两侧的正反面部分加以扫描取得资料，再与记忆体中所采集的大量经验资料对比，作为第三项识别标准。3. Using double-sided printing accuracy identification: Since banknotes are printed with double-sided printing, instead of printing on one side and then printing the other side, there is a certain relative relationship between the patterns on the front and back of banknotes; to be able to identify colors The scanner scans the front and back parts of the left and right sides of the banknote to be tested to obtain data, and then compares it with a large amount of empirical data collected in the memory as the third identification standard.

4、利用纸币尺寸鉴别：以马达带动输送带移动夹于输送带之间的待测纸币，并测定马达轴心转动的圈数换算成纸币尺寸，再与参考资料对比，亦作为一项识别标准。4. Use the banknote size identification: use the motor to drive the conveyor belt to move the banknote to be tested sandwiched between the conveyor belts, and measure the number of rotations of the motor axis to convert it into the banknote size, and then compare it with the reference data, which is also used as an identification standard .
