Description

一种基于掌静脉识别的门禁系统 技术领域
本发明涉及门禁系统领域，具体涉及一种基于掌静脉识别的门禁系统。
背景技术
现有的公司，由于内部资料需要保密，而大多采用电脑进行办公，并没有采用过多的保护系统对资料进行保密，外来人员容易进入，窃取资料，因此需要对外来人员的信息进行采集，以保证资料的安全性，当有资料丢失或者物件丢失时，可追踪到丢失原因；并且现有的工作人员上班采用打卡的方式签到，而工作人员前来工作时，首先就是打开办公室门，因此将门禁系统与打卡相结合，即节省打卡机占用的空间，也能准确记录打卡的时间；同时，现有的门禁系统，无法远程控制打开，例如，当约定外来人员前往办公室取件时，抑或办公室内有物件损坏需要维修时，需要请工人上门维修，而又无法前往办公室的情况下，则会导致外来人员无法进入，需要办公人员前往办公室，则会占用办公人员的时间；基于上述存在的缺陷，提出一种基于掌静脉识别的门禁系统。
发明内容
为了克服现有技术中的不足，本发明提出基于掌静脉识别的门禁系统，不仅可控制工作人员的进出，也满足了打卡需求，同时可远程控制是否允许外来人员进入，约定的人员通过输入身份信息后即可进入，无关人员则被禁止入内，安全性高，解放了工作人员的时间。
为了实现上述目的，本发明的一种基于掌静脉识别的门禁系统，一种基于掌静脉识别的门禁系统，包括主控芯片、掌静脉传感器、图像处理器、触控显示屏、摄像头、人脸识别模块、身份验证模块、开关控制模块、电子锁、信息存储模块和终端设备，所述掌静脉传感器的输出端与图像处理器的输入端相连接，图像处理器的输出端与主控芯片的输入端口相连接；
所述摄像头的输出端与主控芯片的输入端口相连接；所述触控显示屏、人脸识别模块、身份验证模块和信息存储模块与主控芯片互联；
所述主控芯片的信号输出端子与开关控制模块相连，开关控制模块的输出端与电子锁相连；所述主控芯片与终端设备相连。
优选的，主控芯片采用芯片U1，芯片U1的型号为STM32F。
优选的，主控芯片接出有第一无线收发模块，终端设备接出有第二无线收发模块， 主控芯与终端设备通过第一无线收发模块以及第二无线收发模块无线通信。
优选的，触控显示屏采用芯片U2，芯片U2的脚3连接到电阻R13的输出端，电阻R13的输入端连接到芯片U1的脚38，芯片U2的脚19连接到芯片U2的脚31，芯片U2的脚20连接到芯片U2的脚30。
优选的，信息存储模块采用芯片U3,芯片U3的脚6连接到芯片U1的脚29，芯片U3的脚5连接到芯片U1的脚22。
优选的，开关控制模块包括三极管Q1和继电器K1，三极管Q1的输入端连接到电阻R30的输出端，并连接到电容C22的输入端，以及连接到电阻R31的输入端，电容C22的输出端、电容C22的输出端与三极管Q1的发射极相连后接地，电阻R30的输入端连接到芯片U1的脚14；所述三极管Q1的集电极连接到继电器K1的脚1，继电器K1的脚1接电源输入端，继电器K1的脚3接地，继电器K1的脚4连接到电容C23的输入端，并连接到电子锁的电源输入端。

作为本发明的一种技术优化方案，如图3所示，主控芯片1采用芯片U1，芯片U1的型号为STM32F。
通过采用上述技术方案，芯片U1用以接收图像处理器3传输来的掌静脉信息，接收摄像头5传输来面部图像信息，并将传输来的图像信息传输给人脸识别模块6进行分析；用 以接收触控显示屏4输入的身份信息，用以将面部信息、掌静脉信息以及身份信息传输到信息存储模块10进行存储。
作为本发明的一种技术优化方案，如图1-2所示，主控芯片1接出有第一无线收发模块12，终端设备11接出有第二无线收发模块13，主控芯片1与终端设备11通过第一无线收发模块12以及第二无线收发模块13无线通信。
通过采用上述技术方案，当掌静脉信息及面部信息匹配均不通过时，外来人员即可通过触控显示屏4输入身份信息，主控芯片1通过第一无线收发模块12向终端设备11发送身份信息，终端设备11通过第二无线收发模块13接受身份信息，第二无线收发模块13将身份信息传输给终端设备11，终端设备11即可了解到身份信息，后台人员及可发送通过第二无线收发模块13发送允许进入指令以及禁止进入指令给主控芯片1，主控芯片1通过第一无线收发模块12接受到指令，当接收到允许进入指令后，主控芯片1控制开关控制模块8的继电器K1闭合，为电子锁9供电，电子锁9得电打开，外来人员即可进入，当接收到禁止进入指令后，主控芯片1控制开关控制模块8的继电器K1处于断开状态，为电子锁9不通电，电子锁9不打开，外来人员无法进入；采用上述方式，即使放假办公室无人时，办公室内部设备需要外来人员进行维修抑或需要办公室以外人员前去办公室取物件时，可远程控制电子锁9打开，无需办公人员前去开门，并且可对外来人员信息进行采集，大大提高了安全性。
上述具体实施方式仅仅对本发明的优选实施方式进行描述，而并非对本发明的保护范围进行限定。在不脱离本发明设计构思和精神范畴的前提下，本领域的普通技术人员根据本发明所提供的文字描述、附图对本发明的技术方案所作出的各种变形、替代和改进，均应属于本发明的保护范畴。本发明的保护范围由权利要求确定。
