移动终端唤醒方法、装置及移动终端 【技术领域】
本发明涉及移动终端控制技术领域，尤其是涉及一种移动终端唤醒方法、装置及移动终端。
【背景技术】
智能手机进入触摸屏时代后，出于防止误触和省电的目的，在手机待机状态下会熄灭屏幕且关闭触摸屏。在用户需要使用手机时，采用一定的机制唤醒屏幕，解锁进入用户界面。现有的唤醒屏幕机制主要有自动唤醒和手动唤醒两种：手动唤醒主要是通过按压电源侧键唤醒屏幕，自动唤醒往往和自动解锁组合在一起，以提供给用户更为方便的使用体验。
现有的自动唤醒及解锁方案主要包括指纹识别和面部识别。采用指纹自动唤醒及解锁的方案，存在以下问题：指纹模块在手机息屏锁定的状态，也需要工作，以保证随时可以唤醒，因此在手机息屏待机时，指纹模块也在持续耗电。采用面部识别的方案，存在以下问题：面部识别一般采用前摄像头拍摄用户照片进行，在手机息屏锁定状态下，采用加速度传感器或者陀螺仪侦测手机的运动状态，若手机出现加速度变化或者运动状态变化，则唤醒前摄像头拍摄照片。这种方式很容易导致在运动过程中，频繁唤醒手机拍照，导致耗电增加。

现有的移动终端，可以使用指纹或者人脸识别进行唤醒或者解锁，指纹采集模块、加速度传感器或者陀螺仪处于持续工作状态，以保证用户在触摸指纹采集区或者晃动移动终端时，可以及时唤醒处于休眠状态的移动终端，耗电量较高。如果采用人脸识别的方式进行解锁，在移动终端出现加速度变化或者运动状态变化时，则唤醒前摄像头拍摄照片，很容易导致在运动过程中，频繁唤醒手机拍照，导致耗电增加。基于节能的考虑，本发明下述实施例提出一种移动终端唤醒方法来降低唤醒过程中的能耗，详见下述实施例。
在介绍上述方法之前，先对红外辐射和热电器件做简单介绍。人体会辐射出红外线，根据热辐射维恩位移定律：λmT＝2898μm·K，即辐射强度极大值所对应的波长与其绝对温度成反比。正常情况下，人体未被衣物遮盖的脸部区域其温度为固定值，约为人体正常体温37℃左右，因此根据上述维恩位移定律，人体未被衣物遮盖的头部和脸部区域的辐射强度最大值所对应的红外辐射波长约为9.4μm，而人体其它被衣物遮盖区域，其温度低于体温，因此其辐射强度最大值所对应的波长大于9.4μm。
热电器件为主要是一种由高热电系数的材料，如锆钛酸铅系陶瓷、钽酸锂、硫酸三甘钛等制成的探测元件。这些材料具有热释电效应，即极化强度随温度改变而表现出的电荷释放现象，宏观上是温度的改变使在材料的两端出现电压或产生电流。热释电效应与压电效应类似，热释电效应也是晶体的一种自然物理效应。△Ps＝P△T，△Ps为自发式极化强度变化量；△T为温度变化；P为热释电系数。
实施例一
参见图2所示的一种移动终端唤醒方法的流程图，该方法应用于移动终端，该移动终端包括红外热释电传感器，该方法包括如下步骤：
步骤S202，如果移动终端处于锁屏状态，通过红外热释电传感器接收红外光信号；
人体会辐射出红外线，而在正常使用手机的情况下，人的面部会正对着移动终端，因此移动终端可以接收面部发射出的红外光。人的身体由于衣物的遮盖，其对外表现的温度会低于脸部的温度，根据前述内容可知，不同温度的物体辐射的波长不同，因此可以基于红外热释电传感器仅接收对应于脸部温度的波长的红外光，例如通过选择合适接收波长范围的红外热释电传感器，或设置波长过滤元件等方式实现。如此，可以降低其他温度物体对唤醒过程的干扰。
在移动终端处于锁屏状态时，即移动终端的屏幕处于熄灭状态(用户无法直接对屏幕进行触摸操作)且摄像头或指纹识别模块等用于移动终端解锁的元件处于停止工作状态或非开启状态，或者屏幕处于点亮状态但是还未解锁，同时摄像头或指纹识别模块等用于移动终端解锁的元件处于停止工作状态或非开启状态，可以通过红外热释电传感器被动接收用户脸部发射的红外光。上述红外热释电传感器本身不发出任何类型的辐射，因此器件功耗很小。该红外光信号可以使用红外光热释电传感器输出的电压信号、电流信号或者其他表征信号性质的参数表示。
步骤S204，判断红外光信号是否符合预设的唤醒条件。如果是，执行步骤S206；如果否，结束。
其中，预设的唤醒条件既可以是红外光信号的阈值范围，也可以是电压信号的预设类型波形。该唤醒条件可以基于用户在真实唤醒意图时，进行的操作 来确定。例如，用户在欲唤醒移动终端时，通常会将移动终端拿起正对面部，或者在面前晃动，或者手持移动终端旋转等，可以基于上述操作确定预设的唤醒条件，即将上述操作下红外光信号的特点作为唤醒条件的内容，当判断当前采集的红外光信号符合上述特点时，即可认为用户做出了欲唤醒移动终端的操作，可以降低误唤醒的情况。
步骤S206，唤醒移动终端。
在根据电压信号是否符合预设的唤醒条件，确定用户欲唤醒移动终端时，唤醒该移动终端。其中唤醒该移动终端，可以是向移动终端的屏幕和/或解锁装置输出唤醒信号。该解锁装置可以包括指纹模块、摄像头等。上述唤醒动作可以是，例如点亮屏幕供用户进行触摸操作(包括供用户输入解锁密码、选择解锁方式、选择快捷操作等)、唤醒指纹模块进行指纹采集、唤醒摄像头进行拍照或者摄像。可以理解的是在唤醒之前，该屏幕、指纹模块或摄像头是处于停止工作状态或者非开启状态的。通过低功耗的红外热释电传感器持续工作，在需要解锁时才唤醒高功耗的屏幕、指纹模块或摄像头进行识别解锁，从而可以降低移动终端待机过程中的功耗。
本实施例提供的上述方法，当移动终端处于待机睡眠状态时，可以通过红外热释电传感器被动接收人体面部发射的红外光，并将其转换为电压信号，仅在该电压信号符合预设的唤醒条件时唤醒移动终端，可以基于接收的人体面部红外光进行自动唤醒，节能省电，从而可以延长终端的待机时间。
一般情况下，需要仅接收人体脸部的红外光，而对其他波长的红外光进行过滤，可以在上述红外热释电传感器中设置滤光元件，上述红外热释电传感器可以包括汇聚透镜、滤光层和热电探测元件。在接收到该红外光后，将其转换为电压信号，以进行后续判断。将红外热释电传感器输出的信号转换为电压信号，可以采用现有方式，在此不再赘述。上述通过红外热释电传感器接收红外光信号的步骤，可以包括：
(1)通过汇聚透镜汇聚外界环境中的红外光。该汇聚透镜可以将外界环境中的红外光集中入射到热电探测元件上，并限制可以入射到热电探测元件的红外光的角度，使设置角度范围内的红外光才可以触发唤醒。
(2)通过滤光层对汇聚后的红外光进行滤光，仅使来自面部发射的红外光到达热电探测元件。该滤光层可以通过预设波长范围的红外光，该预设波长范围对应人体面部温度正常情况下发射的红外光的波长范围，例如该滤光层的可透光的波长范围可以为9～10μm。
(3)通过热电探测元件将红外光转换为电压信号，并将该电压信号作为红外光信号。
当红外热释电传感器将面部发射的红外光转换为电压信号后，需要判断该电压信号是否符合预设的唤醒条件。本实施例还给出了判断是否符合的方式， 可以基于电压信号的阈值范围，也可以基于电压信号的预设类型波形。下面分别对上述方式进行说明。
(1)基于电压信号的阈值范围。判断电压信号对应的电压值是否大于第一电压阈值且小于第二电压阈值。其中，第一电压阈值和第二电压阈值分别为红外热释电传感器距离红外光的光源为第一距离和第二距离时，红外热释电传感器输出的电压值，且第一距离小于第二距离。该第一距离和第二距离组成方范围，为用户在正常使用移动终端时，大多数情况下面部与移动终端的距离范围。如果电压值满足上述条件，则确定电压信号符合预设的唤醒条件。
(2)基于电压信号的预设类型波形。判断电压信号的波形是否属于预设类型的波形。由于红外热释电传感器可以被多次触发，输出多个电压信号，从而具有一定的波形形状，可以通过判断该波形形状提高唤醒的准确度，真实反映用户的唤醒意图。不同的波形可以对应于移动终端不同的动作特征，例如晃动或者旋转等。如果电压信号的波形满足上述条件，则确定电压信号符合预设的唤醒条件。在此情况下，未考虑用户面部与移动终端的距离的影响。
(3)基于电压信号的阈值范围和预设类型波形。首先判断电压信号对应的电压值是否大于第一电压阈值且小于第二电压阈值，其次判断电压信号的波形是否属于预设类型的波形，当两者均满足时确定电压信号符合预设的唤醒条件。同时考虑上述两种判断方式，可以进一步提高唤醒的准确度。
考虑到用户在唤醒移动终端后，还需要解锁该移动终端，上述方法还可以包括控制移动终端解锁的步骤。该解锁的方式可以是图像解锁、指纹解锁、语音解锁或者密码解锁等，以下以图像解锁为例进行说明。控制移动终端解锁的步骤可以包括：启动移动终端的摄像头进行图像采集；将采集的图像与预先存储的图像进行对比；当对比匹配时，控制移动终端解锁。当对比不匹配时，控制移动终端发出提醒或者报警。
由于移动终端在较暗的环境中进行图像采集时，容易出现采集失败的情况，在进行图像采集前，可以先启动移动终端的光线传感器进行环境光检测，如果环境光检测结果小于环境亮度阈值，则控制移动终端的前置补光灯或屏幕开启。
为了方便用户使用，可以将移动终端解锁和开启某种功能或应用软件绑定，实现解锁后快速打开某功能或应用软件，比较方便快捷。例如可以通过以下步骤执行：
(1)获取电压信号的波形的高电平数量和/或低电平数量。
(2)根据预设的解锁规则，确定高电平数量和/或低电平数量对应的解锁操作。其中，预设的解锁规则可以有用户自主设置或者出厂时设置，可以包括不同高电平数量、低电平数量以及两者组合的数量与解锁操作的对应关系。该解锁操作包括解锁移动终端、启动移动终端的应用软件或启动移动终端的内置功能。
(3)控制执行解锁操作。
实施例二
上述实施例提供的移动终端唤醒方法，可以由自动唤醒系统完成，以下对自动唤醒系统进行详细介绍。
参见图3所示的自动唤醒系统的原理示意图，该自动唤醒系统由透镜31、滤光膜32、热电材料33及电路组成。
其中，透镜的作用是将光线折射到热电材料上，滤光膜的作用是滤除人体头脸部产生的9.4um波长以外的其他光线，以保证投射到热电材料上的光是人体头脸部所产生的红外辐射。可以将滤光膜所能透过的波长范围控制在9～10μm。
如图3中所示，热电材料33包括以反极性串联的两个探测元件，可以抑制由于自身温度升高而产生的干扰。由探测元件将探测并接收到的红外辐射转变成微弱的电压信号，该电压信号经放大器放大后，送入两个比较器进行比较。其中，比较器A的正端接固定电压信号VA，该信号电压与头脸部距离唤醒系统距离为A时，放大器输出的电压值相同；比较器B的负端接固定电压信号VB，该信号电压与头脸部距离唤醒系统距离为B时，放大器输出的电压值相同，两个比较器的比较结果送入与门进行与运算。因此，当手机使用者的头脸部距离唤醒系统距离大于B而小于A时，唤醒系统输出唤醒信号，而在小于等于B或者大于等于A时，唤醒系统不输出唤醒信号。例如，B取10cm，A取人的手臂长度，约为1m。以保证手机在手持阅读状态下或者手持自拍状态下被唤醒。
在图3中的透镜、滤光膜及热电器件均可以设计为矩形，沿透镜的短边方向分布有若干直角三角形的棱镜，这些小棱镜直角边与以平面透镜相接，另一直角边与平面透镜垂直，以平面透镜的水平中心对称设置。透镜上侧为平面，下侧为锯齿状。在此需要说明的是，也可以使用圆形透镜。例如，可以将移动终端屏幕的一部分作为平面透镜，以使得透镜整体不会屏幕所在平面。如果透镜厚度超出屏幕所在平面，可以增加直角三角形棱镜数量，减小单个直角三角形棱镜的高度。例如，上述唤醒系统安装在手机屏幕下，则图3中的平面透镜即为手机屏幕，平面透镜的长边沿手机短边排布，直角三角形棱镜延手机长边排布。
参见图4所示的透镜折射原理示意图，当人体发出的红外线垂直由透镜上表面平面进入棱镜的直角边，光线不发生折射，当光线从棱镜斜边射出时，会发生折射。由于外部空气的折射率小于透镜的折射率，出射角大于入射角，光线将向中间聚拢。参见图5所示的透镜折射角度的示意图，可以通过设置各个小三角棱镜的角度，使得光线只能在与透镜水平方向垂直的一个很小范围内被折射到热电器件上，从而限制能够进入热电器件的光的角度，提高识别唤醒动作的精度。
参见图6所示的移动终端旋转示意图，当人体沿终端的短边在屏幕前经过时，运动到图5所示的角度范围内时，唤醒系统即可输出唤醒信号。如果反复经过，例如终端在用户面部之前晃动，唤醒信号会反复输出，可以参见图7所示的唤醒信号的矩形波示意图；例如终端以长边为Y轴，绕Y轴小范围反复旋转时，唤醒信号也会反复输出，可以参见图8所示的唤醒信号的矩形波示意图，其中在旋转时，面部的红外光会依次入射一侧的探测元件、空隙及另一侧的探测元件。终端可以对上述唤醒信号的波形进行判断，若符合预设的波形类型，则进行唤醒操作。在唤醒时，还可以快速启动移动终端的应用软件或内置功能，例如可以通过设置不同高电平数量、低电平数量以及两者组合的数量与解锁操作的对应关系，来确定用户的快速启动命令。以图7为例，其中包括4个高电平信号，可以设置4个高电平信号对应于启动拨号功能；例如仅有2个高电平信号，可以对应于仅解锁手机，仅有3个高电平信号，可以对应于打开微信等。可以理解的是，也可以使用低电平信号与解锁操作的对应关系进行快速解锁。
本实施例提供的上述方法及自动唤醒系统，可以通过自动唤醒系统输出唤醒信号及唤醒信号的波形，在输出唤醒信号或唤醒信号的波形符合预设的波形类型的情况下才唤醒移动终端，节能省电，可以延长终端的待机时间。
