第一级图像传感器 110和第二级图像传感器 120分别位于传输通道 2的上下 两侧。 第一级图像传感器 110可识别纸币第一面的图像信息, 第二级图像传感 器 120可识别纸币第二面的图像信息。
第二级图像传感器 120的相反一侧设有光源 121。 当纸币 1经过第二级图像 传感器 120时, 光源 121发光, 第二级图像传感器 120可识别纸币的透射图像。 透射图像包括可透视的水印图案和利用一定波长的光可视的图案, 例如, 在紫 光灯照射下可视的图案。
本实施例中, 还包括多组传动轮, 分别配置在传送通道 2的上下两侧的主 动轮 11、 13、 15、 17 , 以及从动轮 10、 12、 14、 16。 通过交替配置的各传感器 之间的四组传动轮的夹送以及外部动力结构 (图未示) , 纸币 1得以在纸币高 速识别装置中沿进钞方向 A传输。
磁传感器 130在传输通道 2的相反一侧设有可上下微调节的螺纹弹性圆柱 状传送辊 131 , 用于微调节纸币 1与磁传感器 130之间的距离。 由于当纸币 1与磁 传感器 130之间的距离过大,使磁传感器 130识别的信息较弱, 不利于准确的判 断纸币的真伪, 因此需要保证纸币 1能很好的与磁传感器 130贴近, 更好的检测 纸币 1表面的磁性信息,使磁信号保持较大的幅值和较高的信噪比,便于识别。
上述每个传感器都对应有至少一个对射型光学传感器 20、 21、 22, 对射型 光学传感器 20位于第一级图像传感器 110的前沿, 对射型光学传感器 21位于磁 传感器 130的前沿,对射型光学传感器 22位于第二级图像传感器 120的前沿, 用 于消除纸币 1在传输过程中引起倾斜后带来的累计误差。 具体的操作方法, 将 在后面详细阐述。
第一级图像传感器 110和第二级图像传感器 120可为 CCD ( Charge Coupled Device,电荷禺合元件 ), 或 CMOS( Complementary Metal-Oxide Semiconductor, 金属氧化物半导体元件), 或 CIS ( Contact Image Sensor, 接触式感光图像传 感器) 。
如图 3所示, 图 3为本发明第二实施例中纸币高速识别装置的主视图。 第二 实施例中增加了位于第一级图传感器 110相反一侧的光源 111 ,和一组位于传输 通道 2末端的对射型光学传感器 23。 该纸币高速识别装置可以实现从 A、 B两个 方向均可以传输纸币 1。 第一级图像传感器 110和第二级图像传感器 120均可以 识别纸币 1的初始信息和根据初始信息识别纸币 1的图像真伪信息。 当纸币 1从 主进钞方向 A进入传输通道 2时, 对射型光学传感器 20消除累计误差, 第一级 图像传感器 110识别纸币 1的初始信息, 光源 111熄灭, 光源 121发光, 第二级图 像传感器 120识别纸币 1的表面图像真伪信息和透射图像真伪信息。 当纸币 1从 次进钞方向 B进入传输通道 2时, 对射型光学传感器 23消除累计误差, 第二级 图像传感器 120识别纸币 1的初始信息, 光源 121熄灭, 光源 111发光, 第一级图 像传感器 110识别纸币 1的表面图像真伪信息和透射图像真伪信息。
本实施例中, 光源 111和 121在识别过程中, 还可同时发光, 当纸币 1从 主进钞方向 A进入传输通道 2时, 第一级图像传感器 110识别纸币 1的初始 信息后, 并根据初始信息, 识别纸币 1 第一面和 /或部分的图像真伪信息; 第 二级图像传感器 120根据初始信息, 识别纸币 1第二面和 /或另一部分的图像 真伪信息;最后第一级图像传感器 110和第二级图像传感器 120交互识别第一 级图像传感器 110所识别的图像真伪信息与第二级图像传感器 120所识别的图 像真伪信息, 从而可以更严格、 更精准的实现纸币的真伪识别。 当纸币 1从次 进钞方向 B进入传输通道 2时, 同理类似上述识别方式。
本实施例中 LF 第一图像传感器 110与第二图像传感器 120对称分布在 磁传感器 130的左右。 因此, 无论是主进钞方法 A还是次进钞方向 B , 两级图像 传感器 110 , 120和磁传感器 130在获取纸币信息和识别的过程中都可以相互参 考。
如图 4所示, 为本发明一实施例中纸币高速识别方法的流程图。 纸币高速 识别方法, 包括以下步骤:
S401 , 提供厚度传感器, 检测纸币的厚度, 判断纸币是否重钞; 本实施例中, 一次只能识别一张纸币, 因此需要厚度传感器判断纸币是否 重钞, 如果重钞, 退回多余纸币, 仅保留一张纸币通过传输通道。
S402, 提供第一级图像传感器, 识别纸币的初始信息;
初始信息包括, 纸币的币种, 面值, 面向等图像信息。
S403 , 根据初始信息, 从纸币信息库中提取相应的磁防伪标识; 磁防伪标识包括, 真钞表面的磁性油墨和金属安全线编码。
5404, 提供磁传感器, 根据磁防伪标识, 识别纸币的磁真伪信息; 磁真伪信息包括, 纸币表面的磁性油墨和金属安全线编码信息。
5405 , 根据初始信息, 从纸币信息库中提取相应的图像防伪标识; 图像防伪标识包括真钞的表面图像和透射图像。表面图像包括各种纸币表 面可视的各种图像, 包括人像、 风景、 文字、 色彩等。 透射图像包括真钞内在 日光下可透视的水印图案、利用一定波长的光可视的图案, 例如在紫光灯的照 射下可视的图案。
5406, 提供第二级图像传感器, 根据图像防伪标识, 识别纸币的图像真伪 信息。
图像真伪信息包括纸币的表面图像信息和透射图像信息。
例如, 当输入一张纸币进入到传输通道中, 第一级图像传感器识别到纸币 为币种为人民币, 面值为一百元; 纸币高速识别装置的主控制系统(图未示) 根据一百元的人民币,从纸币信息库中来提取该种纸币的防伪标识包括: 四伟 人头像的表面图像, 毛泽东水印头像的透射图像,磁性油墨和金属安全线编码 的磁真伪标识等; 第二级图像传感器和磁传感器根据提取的防伪标识,有针对 性地识别纸币的相应的信息。这种识别方法, 由于不需要对纸币所有的信息都 进行识别,再判断是否真伪, 而是根据纸币的币种和面值有针对性的识别相应 的信息, 有效地节省了识别的时间, 提高了识别的精度。
本实施例中,每个运用上述传感器的步骤之前,都要利用对射型光线传感 器, 消除纸币在传输过程中引起倾斜后带来的累计误差。
如图 5所示, 为本发明另一实施例中纸币高速识别方法的流程图。纸币高 速识别方法, 包括以下步骤:
S501 , 提供第一级图像传感器, 识别纸币的初始信息; 5502, 根据初始信息, 从纸币信息库中提取相应的图像防伪标识;
5503 , 第一级图像传感器, 根据图像防伪标识, 识别纸币的一部分图像真 伪信息;
一部分图像真伪信息, 包括纸币正面和 /或部分图像真伪信息。
S504, 根据初始信息, 从纸币信息库中提取相应的磁防伪标识;
5505 , 提供磁传感器, 根据磁防伪表示, 识别纸币的磁真伪信息;
5506, 提供第二级图像传感器, 根图像防伪标识, 识别纸币的另一部分图 像真伪信息;
另一部分图像真伪信息,包括纸币的除第一级图像传感器识别的信息外的 反面和 /或另一部分的图像真伪信息。
5507,第一级图像传感器和第二级图像传感器交互识别一部分图像真伪信 息与另一部分图像真伪信息。
该方法可以更严格、 更精准的实现纸币的真伪识别。
图 6为本发明实施例中纸币高速识别方法主进钞方向 A中的工作示意图, 在主进钞方向 A中, 当对射型光学传感器 20探测到纸币 1进入识别装置时, 依据对射型光学传感器 20与第一级图像传感器 110的距离 "和已知的钞票传 输速度, 即可计算出钞票到达第一级图像传感器 110的时间 从而可以有效 的控制第一级图像传感器的初始化和触发时序, 获取纸币信息。 同样的, 依靠 对射型光学传感器 21、 22、 23与各识别传感器 120、 130、 140的距离 c、 d 计算出钞票到达的时间,控制各传感器的初始化和工作时序。这样就消除了依 靠单一传感器来触发引起的由于钞票在传输过程中产生倾斜后带来的累计误 差。
同样的, 图 7本发明实施例中纸币高速识别方法次进钞方向 B中的工作 示意图, 在次进钞方向 B中, 依据上述主进钞方向 A的相同原理, 对射型光 学传感器 23作为纸币进入识别装置探测标识, 并依靠对射型光学传感器 23、 22、 21与各识别传感器 140、 120、 130、 110的距离 ef、 g计算出钞票到 达的时间, 控制各传感器的初始化和工作时序。
上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在本发明 的精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明 的保护范围之内。
