其中一个实施例为，所述指纹采集仪3为圆形指纹采集仪，便于用户单手操作，单手拇指可以手握把手，同时按压指纹区域。优选的本申请采用的指纹采集仪为圆形的电容式指纹传感器(半导体电容式指纹传感器)，其工作过程是通过对每个像素点上的电容感应颗粒预先充电到某一参考电压。当手指接触到半导体电容指纹表现上时，因为嵴是凸起、峪是凹下，根据电容值与距离的关系，会在嵴和峪的地方形成不同的电容值，然后利用放电电流进行放电。因为嵴和峪对应的电容值不同，所以其放电的速度也不同。嵴下的像素(电容量高)放电较慢，而处于峪下的像素(电容量低)放电较快。根据放电率的不同，可以探测到嵴和峪的位置，从而形成指纹图像数据。电容传感器采用自动控制技术调节指纹图像像素以及指纹局部范围敏感程度，在不同环境下结合反馈信息生成高质量图像。由于提供了局部调整能力，即使对比度差的图像(如手指压得较轻的区域)也能被有效检测到，并在捕捉瞬间为这些像素提高灵敏度，生成高质量指纹图像。其发出的电子信号将穿过手指的表面和死性皮肤层，达到手指皮肤的活体层(真皮层)，直接读取指纹图案，从而大大提高了系统的安全性。能够在较小的表面上获得比光学技术更好的图像质量，在1cm×1.5cm的表面上获得200-300线的分辨率(较小的表面也导致成本的下降和能被集成到更小的设备中)。本申请所采用的圆形的电容式指纹传感器体积小、成本低，成像精度高，而且耗电量很小。
本申请提供的智能门锁，在把手的连接端同心设置有圆形或椭圆形的指纹采集仪，在用户使用把手的过程中同步完成解锁达到开门的目的，并通过发光显示装置进行灯环提示，以提示用户解锁成功与否，并与整体开门动作单手操作一步到位，可以在数秒内操作完毕，实现了下压把手的一步到位开门解决方案，便于用户打开门体。
本发明实施例进一步的提供智能门锁的几种具体的设计结构，请参考图4至图14，在一种具体实施方式中，本发明提供的智能门锁包括指纹采集仪3、指纹电路板2及把手5，指纹采集仪3与指纹电路板2连接，具体的，指纹电路板2为PCB板，为了减小整体水平面面积，优选该PCB板由多层依次叠加而成，指纹电路板2位于把手5内部，把手5上设有与指纹采集仪3适配的采集仪安装孔53，指纹采集仪3为半导体指纹采集仪。具体的，采集仪安装孔53可以设置在把手5的上表面上。当然，指纹采集板31可以设置在指纹电路板2的正上方，指纹采集板31的指纹采集面与指纹电路板2垂直设置，指纹采集板31的轴线与把手5的旋转轴线重合，指纹电路板2长度方向沿旋转轴线方向布置。为了便于使用者打开门体，优选，指纹采集板31的指纹采集面与水平面垂直布置。使用者指纹采集板31与使用者正对，当把手5为旋转把手时，根据开门习惯，当使用者手握把手5时，拇指正好放置在指纹采集板31位置。
指纹采集仪包括指纹采集板31及包设在支撑采集板31侧面的金属保护环32，金属保护环32内侧面设有用于支撑指纹采集板31的采集板支撑面33。通过设置金属保护环32用于保护指纹采集板31不因组装装配的机械压力影响。为了减小指纹采集仪3的占用面积，且提高指纹解锁时的舒适性，指纹采集板31为圆形板，具体的，指纹采集板31直径φA为12mm～15mm，具体的，指纹采集板31直径φA为14mm或12.9mm。为了保护指纹采集板31不因机械应力影响，也兼顾美观金属保护环32内径与外径之差为1.2mm～2mm，即金属保护环32上圆环尺寸D为0.6mm～1mm，金属保护环32上圆环尺寸D为0.8mm。优选，采集板支撑面33为与指纹采集板31适配，且由上至下渐缩的锥形面，便于指采集仪整体组装。为了提高密封性和支撑可 靠性，优选金属保护环32为阶梯型结构，具体的，金属保护环32上设有外凸于采集板支撑面33的采集仪安装面34。当然，在具体制造过程中，可以根据把手5具体形状，可以将指纹采集板31和保护金属环32可以为方形或其它形状。
进行智能门锁的组装时，采集仪组装端71穿过端盖安装端52，最终使得指纹采集仪卡在采集仪安装孔53位置，完成与把手5的组装。当使用者需要打开门体时，使用者手握把手5，手指对准指纹采集仪3，当指纹验证通过时，当为图示中的旋转把手时，下压把手开门；如果是推拉锁，直接拉动开门。
通过上述描述可知，在本申请具体实施例所提供的智能门锁中，由于指纹采集仪3为半导体指纹采集仪，且指纹电路板2安装在把手5位置，整体结构较小。将指纹采集仪3安装在把手5上，将指纹电路板2安装在把手5内部，使用者一只手握在把手5上即可完成指纹验证及开启门体的操作，操作简单，便于使用者打开门体。
进一步，该智能门锁还包括固定架1，固定架1包括端盖7及伸入把手5内部的固定板14，固定板14的相对两侧均设有外凸于固定板14，且用于卡接指纹电路板2的绝缘加强筋11，指纹电路板2上设有与绝缘加强筋11卡接的支撑凸起21，即支撑凸起21设置在电路板本体22上，优选，电路板本体22相对两侧对称设有支撑凸起21，绝缘加强筋11上与支撑凸起21抵接的位置形成卡接端面111。优选，固定架1的端部包设在指纹采集仪3的侧面，具体的，优选，绝缘加强筋11延伸至固定板14的端部与指纹采集仪3的侧面抵接。具体的，绝缘加强筋11可以与端盖7固定连接。由于指纹电路板2与固定架1通过卡接固定，避免使用螺钉等其它部件固定，组装简单，避免组装过程中指纹电路板2发生形变的情况，有效地延长了指纹电路板2及固定架1的使用寿命。通过设置绝缘加强筋11，指纹电路板2的底面不会贴着固定架1的底面，避免出现指纹电路板2的元器件和金属部件接触。
进一步，该固定架1还包括用于支撑指纹采集板31的支撑板13，优选，支撑板13为绝缘件，支撑板13具体可以与绝缘加强筋11连接或与端盖7连接。
优选的，固定板14的相对两侧均设有两个绝缘加强筋11，固定板14一侧相对的两个绝缘加强筋11之间形成用于卡接支撑凸起21的支撑卡槽12，指纹电路板2的支撑凸起21卡接在支撑卡槽12内。
进一步，该固定架1还包括能够与固定板14扣合的固定盖4，固定盖4上设有能够卡接于支撑卡槽12上的卡接凸起41，当固定盖4为金属结构时，固定盖4与指纹电路板2间隔布置。通过设置固定盖4与固定板14配合，结构简单，使得整体强度提高，有效地提高了智能门锁的使用安全性。
为了延长固定盖4的强度，优选，固定盖4内表面设有加强筋，其中加强筋的个数根据实际情况而定，本申请不做具体限定。
为了提高智能门锁的加工效率，优选，固定盖4和固定板14均为一体成型结构。
优选的，把手5包括把手握持部及用于容纳指纹电路板2的安装部，安装部为筒型结构，固定板14和固定盖4均位于安装部内部，端盖7用于封堵安装部开口端，固定板14和固定盖4均通过螺纹紧固件6与安装部连接，具体的，固定盖4上设有供螺纹紧固件6通过的盖体安装孔42，安装部上设有供螺纹紧固件6通过的把手安装孔51。由于安装部为筒型结构，避免指纹采集仪3及指纹电路板2受到损坏，有效地延长了智能门锁的使用寿命。由于固定板14和固定盖4均通过螺纹紧固件6与安装部连接，便于工作人员拆装智能门锁，便于安装及检修。
为了避免组装出现错误，优选，固定盖4的外表面为第一U型面，安装部的内表面设有与第一U型面贴合的第二U型面。具体的，为了便于加工，第一U型面为折线型表面，固定板14的外表面为圆弧形面，更为优选的，固定板14和固定盖4的外表面与安装部的内表面贴合。
为了延长智能门锁的使用寿命，优选，把手5、固定板14和固定杆为金属件，优选为不锈钢结构或者铜质结构。
与上述智能门锁对应的，本发明还提供一种基于智能门锁的开锁方法，参考图3，为本发明实施例提供的一种基于智能门锁的开锁方法的流程图，该方法包括：
步骤101：当指纹采集仪采集到指纹后，将采集到的所述指纹的指纹图像信息输出至指纹模组。
智能门锁的指纹采集仪为设置在智能门锁把手上的圆形或椭圆形的指纹采集仪，可采用电容式指纹传感器，激光指纹传感器，超声波指纹传感器或射频式指纹传感器。例如用户将手指轻压在电容式指纹传感器表面，则指纹传感器采集施加于传感器表面的指纹信息，指纹采集约在100ms内完成；并将采集到的指纹图像信息发送至指纹模组。
步骤102：所述指纹模组将所述指纹图像信息转化为待验证指纹数据信息发送至处理装置。
指纹模组将接收到的指纹图像信息进行识别分析，得到待验证的指纹数据信息；这里的指纹模组用于实现对采集到的指纹图像信息进行识别分析处理，将其转化为指纹数据信息；具体的，在本实施例中对指纹图像信息进行识别分析包括但不限于：对采集到的指纹信息进行过滤，排除一部分干扰信息，并提取指纹特征的数据，得到与指纹图像信息对应的指纹数据信息。
步骤103：所述处理装置将所述待验证指纹数据信息与授权指纹数据信息进行匹配，根据匹配结果控制智能门锁触发开锁命令或报警命令；所述处理装置中存储有多个所述授权指纹数据信息，所述授权指纹数据信息为预先采集的授权用户的指纹图像信息转化得到的指纹数据信息。
具体的，一种实现方式中，步骤103可以包括步骤1031、步骤1032和步骤1033：
步骤1031：所述处理装置将所述待验证指纹数据信息与多个所述授权指纹数据信息逐一进行匹配；根据匹配结果执行步骤1032或1033；
所述处理装置中预存有多个预先采集的授权用户的指纹图像信息转化得到的指纹数据信息；在处理装置接收到待验证的指纹数据信息后，将待验证的指纹数据信息与授权指纹数据信息进行逐一的匹配，并根据匹配结果控制智能门锁触发开锁命令或报警命令。
在本实施例中，授权指纹数据信息为授权用户在指纹采集仪端通过指纹采集输入授权指纹，经过指纹模组分析处理得到的授权指纹数据信息，并将 该授权指纹数据信息保存于所述处理装置的存储模模块中，用于待验证指纹的匹配和验证。
步骤1032：当匹配结果为匹配到与所述待验证指纹数据信息相同的授权指纹信息时，处理装置控制LED发光模组显示预设置的第一提示灯光，并发送开锁指令，以控制智能门锁执行开锁动作；所述第一提示灯光为指示指纹匹配成功的预设灯光。
步骤1033：当匹配结果为未匹配到与所述待验证指纹数据信息相同的授权指纹信息时，处理装置控制LED发光模组显示预设置的第二提示灯光，并触发报警命令生成报警信息；所述第二提示灯光为指示指纹匹配失败的预设灯光。即当匹配结果为未匹配成功时，智能门锁始终保持锁定状态，处理装置触发报警设备生成报警信息并向终端发送预警信息。
当通过智能门锁进行开门时，在指纹授权情况下，用户手握把手，拇指按压圆形指纹采集仪，指纹采集仪采集指纹图像数据，并由指纹模组识别转化输出待验证的指纹数据信息传输给处理装置，处理装置匹配该指纹成功时，反馈信息给灯光环，亮灯显示状态，同时供电给智能门锁的离合组件，同步下压把手时，实现机械联动，开启门锁。
本申请的指纹采集仪设置在把手上，并与把手的连接端为同心设置，实现了指纹采集仪模块结构与把手的同轴性，同时灯光与把手和指纹采集仪同轴，实现了指纹判断与灯光显示效果的同步性。本申请用户使用把手过程中同步完成解锁达到开门的目的，并通过灯环提示效果，显示解锁成功与否，整体开门动作单手操作一步到位，可以在数秒内操作完毕，实现了下压把手的一步到位开门解决方案，便于用户打开门体。
