Description

指纹识别装置
 
技术领域
本发明属于测控技术领域，特别涉及一种指纹识别装置。
背景技术
    指纹指人手指的纹络，两枚指纹经常会具有相同的总体特征，但它们的细节特征，却不可能完全相同。指纹纹路并不是连续的、平滑笔直的，而是经常出现中断、分叉或转折。这些断点、分叉点和转折点就称为"特征点"，就是这些特征点提供了指纹唯一性的确认信息，其中最典型的是终结点和分叉点，其他还包括分歧点、孤立点、环点、短纹等。
发明内容
针对现有技术存在的不足，本发明提供一种指纹识别装置。
本发明的技术方案是这样实现的：该指纹识别装置包括处理器、图像传感器、隔离放大器、驱动器、指示灯和显示屏，其中图像传感器的输出端和隔离放大器的输入端相连接，隔离放大器的输出端和处理器的输入端相连接，处理器的输出端和驱动器的输入端相连接，驱动器的输出端和显示屏相连接，指示灯的输入端和处理器的输出端相连接。
本发明的优点：该指纹识别装置操作简单、稳定性强、体较小、成本低。
附图说明
图1为指纹识别装置简图。
具体实施方式
本发明的详细结构结合实施例加以说明。
该指纹识别装置简图如图1所示，图像传感器选择型号为TCD1209DGZ，处理器选择型号为AT89C1051，隔离放大器选择型号为HCPL-7840，驱动器选择型号为MY9181。
该指纹识别装置包括处理器、图像传感器、隔离放大器、驱动器、指示灯和显示屏，其中图像传感器的输出端和隔离放大器的输入端相连接，隔离放大器的输出端和处理器的输入端相连接，处理器的输出端和驱动器的输入端相连接，驱动器的输出端和显示屏相连接，指示灯的输入端和处理器的输出端相连接。
