Description

一种触摸显示屏的自动唤醒方法和装置、可读写存储介质 技术领域
本发明涉及智能家居领域，尤其涉及一种触摸显示屏的自动唤醒方法和装置、可读写存储介质。
 背景技术
随着智能家居技术的发展和智能家居应用的普及，越来越多的智能家居上开始使用触摸显示屏来代替传统的按键，用作主要的控制输入和人机交互媒介，然而，智能家居与手机、平板等移动设备之间的使用场合并不完全相同，触摸显示屏的控制方法也不完全相同。
为了节省电能损耗、避免光污染以及防止缩短使用寿命，智能家居上的触摸显示屏在大部分时间里都是处于息屏状态的，只有在被唤醒时才能进行触摸操作。目前，智能家居中的触摸显示屏的点亮方式大致有三种，第一种是采用实体按键点亮，这种方式中的实体按键在长期按压后容易发生不可恢复的形变而造成损坏，而且实体按键可能会受空气湿度影响造成生锈等问题，影响用户正常使用；第二种是点击触摸显示屏后点亮，这种方式在黑暗条件下用户不容易找到触摸显示屏的位置；第三种是采用语音识别点亮，这种方式并不是在任何环境下都适合，例如在卧室中使用语音识别就会影响别人的睡眠。
 技术问题
为了解决上述现有技术的不足，本发明提供一种触摸显示屏的自动唤醒方法和装置、可读写存储介质。该自动唤醒方法只需要用户靠近触摸显示屏，而不需要用户亲手去操作，就可以自动点亮触摸显示屏。

 本发明的实施方式
下面结合附图和实施例对本发明进行详细的说明。
实施例一
如图1所示，一种触摸显示屏1的自动唤醒方法，包括：
步骤1：通过检测模块2获取用户的接近信息；
该步骤1中，如图4所示，所述检测模块2包括与所述触摸显示屏1共面的至少两个接近传感器21，优选地，所述至少两个接近传感器21位于在所述触摸显示屏1外围的相对两侧上。
本实施例中，所述检测模块2包括具有接近传感器21的至少两个接近和环境光传感模块，每个接近和环境光传感模块均包括一个接近传感器21、一个环境光传感器22和一个数字转换器，所述接近传感器21和环境光传感器22的输出端分别电性连接至所述数字转换器的输入端；所述数字转换器用于将所述接近传感器21和环境光传感器22输出的模拟信号转换成数字信号后再输出。
所述接近信息由接近传感器21来获取的，所述接近传感器21是一种非接触式的距离传感器，其获取的接近信息有两种，一种是接近信号，即当用户进入其1.5m的感测距离内时，其会变为激活态并输出接近触发信号，当用户离开其1.5m的感测距离内时，其会恢复至静态并输出接近中断信号；另一种是距离数据，即用户在其1.5米的感测距离内时，其通过红外测距方式可以较为精准地获得用户的距离。
另外，如图5所示，所述接近传感器21的红外光上下散射角度是20°，当其离地面的距离合适时，可以很好地满足所有身高的人群。
步骤2：依据获取的接近信息，对用户的接近行为进行建模，绘制成空间接近模型；
该步骤2中，所述空间接近模型是一个动态模型，依据不断获取到的接近信息进行计算、修正以形成不断变化的动态模型。
该步骤2具体包括：
步骤2.1：依据接近信息中的接近信号，判断用户是否走进检测区域，若是，则进行步骤2.2；
如图3所示，第一接近传感器21A以1.5m的感测距离形成第一感测范围，第二接近传感器21B也以1.5m的感测距离形成第二感测范围，那么所述第一感测范围和第二感测范围之间会形成一个重合区域，这个重合区域就是检测区域。
在该步骤2.1中，当用户走进检测区域内时，所述第一接近传感器21A和第二接近传感器21B均变为激活态并发出接近触发信号，依据这两个接近触发信号就可以判断用户已经走进检测区域内。
步骤2.2：依据接近信息中的距离数据，计算出用户的空间位置和移动趋势。
该步骤2.2中，由于所述接近传感器21的测距是没有方向性的，因此需要至少两个接近传感器21同时测距才能确定用户的空间位置。
如图3所示，当用户在检测区域内的任一点时，所述第一接近传感器21A检测到用户与其的第一距离L1，所述第二接近传感器21B检测到用户与其的第二距离L2，而所述第一接近传感器21A和第二接近传感器21B之间的间距D已知，那么就可以通过三角形原理或直角坐标原理进行计算以确定用户的空间位置，以及依据用户的空间位置的变化来确定用户的移动趋势，比如：用户横向穿过触摸显示屏1前方、逐渐远离触摸显示屏1、逐渐靠近触摸显示屏1或在触摸显示屏1前停留等移动趋势。
步骤3：依据预设的用户行为模型，对绘制的空间接近模型进行识别，判断用户是否需要操作触摸显示屏1，若是且触摸显示屏1处于息屏状态，则通过驱动模块点亮触摸显示屏1。
基于同样的原理还能控制触摸显示屏1自动关闭，因此，该自动唤醒方法还包括：
在步骤3中：判断用户是否需要操作触摸显示屏1，若否且触摸显示屏1处于点亮状态，则通过驱动模块关闭触摸显示屏1。
该步骤3中，用户模型在产品出厂时就已经预设好了，由生产厂家的实验人员在实验室中通过穷尽移动趋势的方式来建立预设的用户行为模型，比如将横向穿过触摸显示屏1前方、逐渐远离触摸显示屏1等移动趋势定为无需操作触摸显示屏1，将逐渐靠近触摸显示屏1、在触摸显示屏1前停留等移动趋势定为需要操作触摸显示屏1。
该自动唤醒方法只需要用户靠近触摸显示屏1，而不需要用户亲手去操作，就可以将触摸显示屏1点亮，反应速度快，通过判断用户的接近行为来点亮触摸显示屏1，能够有效防止误判，具有能耗小、触摸显示屏1使用寿命长和光污染少等优势，与现有的触摸显示屏1唤醒方法结合一起使用，能够有效弥补现有的触摸显示屏1唤醒方法中存在的缺陷。
在实际使用时，不同的用户会有不同的行为习惯，因此有必要在使用过程中依据不同用户的行为习惯来对预设的用户行为模型进行校正。
因此，该自动唤醒方法在步骤3之后，还包括：
步骤4：将用户的空间接近模型记录下来；
步骤5：依据记录下来的空间接近模型，对预设的用户行为模型进行校正。
记录下来的主要是作出误判的空间接近模型，比如横向穿过触摸显示屏1前方这个移动趋势在预设的用户行为模型中是无需点亮触摸显示屏1的，但是，用户在多次作出这个移动趋势之后都通过实体按键点亮、点击触摸显示屏1后点亮或语音识别点亮等传统唤醒方法来点亮触摸显示屏1，那么就可以将这个误判的空间接近模型记录下来对预设的用户行为模型进行校正，以适应不同用户的行为习惯。
由于所述接近传感器21采用红外测距，是一种光学器件，可能会发生异物遮挡、保护盖板4脏污等问题而误变为激活状态，影响到正常使用，因此，该自动唤醒方法在点亮触摸显示屏1之后，还包括：
若在第一预设时间内，触摸显示屏1未获取到任何触摸操作且所述检测模块2中的至少一个接近传感器21一直持续检测到用户的接近信息，则判断对应的接近传感器21为异常状态；
对处于异常状态的接近传感器21进行程序加锁处理，并在对用户的接近行为进行建模时，不采用处于异常状态的接近传感器21获取到的接近信息。
该自动唤醒方法可以通过显示、语音等方式将所述接近传感器21的异常状态向用户进行提醒。
对于被程序锁定的接近传感器21只有在异物遮挡、保护盖板4脏污等问题解决之后，由激活态重新恢复至静态后，才能解锁以恢复正常使用，因此，该自动唤醒方法还包括：
若处于异常状态的接近传感器21再次未检测到用户的接近信息，则判断对应的接近传感器21已恢复至正常状态；
对已恢复至正常状态的接近传感器21进行程序解锁，并在对用户的接近行为进行建模时，重新采用恢复正常状态的接近传感器21获取到的接近信息。
若所述检测模块2中只剩下一个接近传感器21为正常状态，则通过该接近传感器21来获取用户的距离数据；
若获取的距离数据小于预设距离且持续时间达到第二预设时间，而触摸显示屏1处于息屏状态，则通过驱动模块点亮触摸显示屏1。
若所述检测模块2中的全部接近传感器21都处于异常状态，则切换至实体按键点亮、点击触摸显示屏1后点亮或语音识别点亮等传统唤醒方法。
