所述处理器100可以是中央处理单元(Central Processing Unit，CPU)，还可以是其他通用处理器、数字信号处理器(Digital Signal Processor，DSP)、专用集成电路(Application Specific Integrated Circuit，ASIC)、现成可编程门阵列 (Field-Programmable Gate Array，FPGA)或者其他可编程逻辑器件、分立门或者晶体管逻辑器件、分立硬件组件等。通用处理器可以是微处理器或者该处理器也可以是任何常规的处理器等。
所述存储装置102可用于存储所述计算机程序和/或模块，所述处理器100通过运行或执行存储在所述存储装置102内的计算机程序和/或模块，以及调用存储在存储装置102内的数据。此外，存储装置102可以包括高速随机存取存储装置，还可以包括非易失性存储装置，例如硬盘、内存、插接式硬盘，智能存储卡(Smart Media Card，SMC)，安全数字(Secure Digital，SD)卡，闪存卡(Flash Card)、至少一个磁盘存储装置件、闪存器件、或其他易失性固态存储装置件。
处理器100获取检测模块110传输的具有属性值的检测信号，并判断检测信号所对应的属性值是否达到预设的阈值。当所述检测信号所对应的属性值达到所述预设的阈值时，表示存在用户触摸导电电极104，此时，处理器100用于记录触摸导电电极104的用户的数量，如增加预设值。当所述检测信号所对应的属性值没有达到预设的阈值时，表示可能是其他物体触碰了导电电极104，此时，处理器100可不进行记录。在一实施例中，处理器100可根据负载的电阻R、对应用户与介质组件间的摩擦发电功率密度H及用户接触所述介质组件的最小接触面积A确定所述预设的阈值，其中，预设的阈值U可表示为：
Figure PCTCN2018125068-appb-000001
由上述公式可知，负载的电阻R可确定，用户与介质组件间的摩擦发电功能密度H亦可确定，因此，预设的阈值与最小接触面积A有关，如此，可通过设置最小接触面积A的值来确定触发信号是否是用户接触导电电极时产生的。本实施例中，预设的阈值可为预设的电压值，如此，处理器100可根据检测信号所对应的电压值来进行判断是否所述检测信号所对应的属性值是否达到预设的阈值。在其他实施例中，预设的阈值可为预设的电流值，由于负载的电阻R是确定的，因此，可根据上述的电压值与负载的电阻R来确定预设的阈值所对应的电流值，进而，处理器100亦可根据检测信号所对应的电流值来 进行判断是否所述检测信号所对应的属性值是否达到预设的阈值。
上述监测装置通过检测用户接触导电电极时所对应的检测信号属性值来统计预设区域内的人流量，有利于减少现有技术中通过图像识别时因人脸遮挡而造成人流量统计的准确度降低的不足。
请参阅图3，所示为本申请的实施例中的电梯30的结构示意图。电梯30包括本体301、及沿所述本体301周长方向运动的扶手303及所述检测系统10。本实施例中，电梯30可设置于商场的入口处，可用于统计进入或离开商场的人流量。扶手303、本体301在电机或其他设备的带动下可沿本体301周长方向上运动，以使得电梯30沿X方向运动，如此可使得用户从电梯30的第一位置或入口处(如图3的右侧)沿X方向移动到电梯30的第二位置或出口处(如图3的左侧)。
检测系统10中的导电电极104设置于扶手303运动的路径上，以使得用户在移动的过程中可触摸导电电极104。导电电极104可设置于电梯30的运动方向的第二位置，或是设置于第一位置与第二位置之间的其他位置。本实施例中，扶手303的外壁设置介质组件305。电梯30的扶手303的外壁可为橡胶层，可的在橡胶层上贴附一层聚四氟乙烯薄膜或涂覆聚四氟乙烯涂层以形成介质组件305。如此，行人在通过电梯30时，手掌在与介质组件305发生轻微碰撞或震动摩擦后会产生一定量的电荷。当行人到达电梯30的第二位置时，为更好的站稳，行人可将手掌接触位于出口处的导电电极104。此时，导电电极104可产生触发信号至检测电路120，并由处理器100来判断是否对于本次的接触产生的触发信号进行人流量的统计。监测装置10具体的处理过程及包含元件的连接关系可参阅上述内容，故在此不再赘述。
本实施例中，当导电电极104设置于电梯30运动方向X的第二位置或出口处时，监测装置10可统计第一方向上的人流量，如统计进入商场的人流量。在其他实施例中，导电电极104可设置于电梯30的第一位置或入口处，此时，若电梯30的运动方向为X的反方向(如电梯30的运行方向由左侧到右侧)，监测装置10可统计第二方向上的人流量，如统计离开商场的人流量。
在一实施例中，电梯30可包括第一扶手及第二扶手，如此，行人在通过电梯30时可站立于第一扶手附近并手掌握住第一扶手或是站立于第二扶手附 近并手掌握住第二扶手，以在电梯30的运行过程中站稳。电梯30可包括第一导电电极及第二导电电极。第一导电电极可设置于电梯30运行的出口处并位于第一扶手运动的路径上，第二导电电极可设置于电梯30运行的出口处并位于第二扶手运动的路径上，第一导电电极及第二导电电极均电性连接于检测电路120，如此，监测装置10可对位于第一扶手附近的用户及位于第二扶手附近的用户进行人流量的统计。
请参阅图4及图5，所示为本申请的实施例中的门的结构示意图。门40包括本体400、设置于本体400上的把手402及所述监测装置10。把手402包括第一安装部410、第二安装部412及位于第一安装部410及第二安装部412之间的连接部414。把手402大致呈“C”字型，其中，第一安装部410及第二安装部410均垂直于本体400，连接部414与本体400大致平行。
连接部414包括第一设置部420及临近第一设置部420设置的第二设置部422，监测装置10的导电电极104可设置于第二设置部422，监测装置10的介质组件112可设置于第一设置部420，监测装置10的检测电路120可电性连接于导电电极104。本实施例中，本体400可包括中空部，检测电路120可通过导线沿中空部连接至导电电路104。当用户打开门40时，用户的手掌可握住把手402，此时，第一安装部420的介质组件112及第二安装部422上的导电电极104可同时与用户手掌接触。当用户用力作用于把手402时，用户的手掌与介质组件112摩擦，产生摩擦电荷。由于用户的手掌还与导电电极104接触，进而使得产生的摩擦电荷通过导电电极104释放，产生触发信号。导电电极104可将产生触发信号至检测电路120，并由处理器100来判断是否对于本次的接触产生的触发信号进行人流量的统计。监测装置10具体的处理过程及包含元件的连接关系可参阅上述内容，故在此不再赘述。通过在门40的本体400的把手上设置介质组件112及导电电极104以统计进入室内的人流量。
在一实施例中，门40包括第一侧面430及与第一侧面430相背设置的第二侧面432，门的把手402可包括第一把手及第二把手，其中，第一把手设置于门40的第一侧面430，第二把手设置于门40的第二侧面432。每一把手第一设置部均可设置介质组件112，每一把手的第二设置部均可设置导电电极104，且监测装置10的检测电路120连接每一把手的导电电极104。如此，当 用户进入室内时，用户的手掌可握住第一把手；当用户离开室内时，用户的手掌可握住第二把手，进而，门40可通过第一把手统计第一方向的人流量，如进入室内的人流量，通过第二把手统计第二方向的人流量，如离开室内的人流量。

处理器可判断检测信号所对应的属性值是否达到预设的阈值来确定是否进行人流量的记录，其中，预设的阈值可为预设的电压值或预设的电流值，预设的阈值根据所述负载的电阻、对应用户与介质组件间的摩擦发电功率密度及用户接触所述介质组件的最小接触面积确定。当检测信号所对应的属性值没有达到预设的阈值时，表示可能是其他物体触碰了导电电极，此时，处理器可不 进行记录。
当所述检测信号所对应的属性值达到所述预设的阈值时，表示存在用户触摸导电电极，此时，处理器用于记录触摸导电电极的用户的数量，如增加预设值。本实施例中，处理器在确定一个检测信号的属性值超过预设的阈值时，处理器可将触摸导电电极的用户的数量增加一个。
上述监测方法通过检测用户接触导电电极时所对应的检测信号属性值来统计预设区域内的人流量，有利于减少现有技术中通过图像识别时因人脸遮挡而造成人流量统计的准确度降低的不足。
