Description

一种屏幕解锁方法、系统及移动终端
【技术领域】
本发明涉及一种屏幕解锁方法、系统及移动终端。
【背景技术】
目前，随着各种移动终端的普及和发展，手机的功能越来越丰富，带给人们的使用体验也越来越好。通常为了防止移动终端处于待机状态时被意外开启，移动终端会自动使待机下的显示屏幕处于锁定工作模式。当需要开启处于锁定工作模式下的移动终端显示屏幕时，通常是通过滑动解锁或固定键盘解锁等，方式比较单一。
另外，为了提升用户体验，也出现了一些比较有创意的解锁方式，比如面部识别解锁、指纹解锁等。这些方式虽然给用户的体验不错，但是系统成本高，消耗电量多，对于结构外观影响大，而且软件集成难度大，成功率不高，目前发展还不是很成熟。
【发明内容】
本发明主要解决的技术问题是提供一种屏幕解锁方法、系统及移动终端，能够使用接近传感器对手势的识别实现屏幕解锁控制。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种屏幕解锁方法，包括：在屏幕被锁状态下，使移动终端的红外接收管接收来自所述移动终端的红外发射管发射而被反射回来的红外光；使所述移动终端的接近传感器先后检测得到预定时间内的多个红外光强度，并把所述光强度转化为数字信息发送给移动终端的基带处理器；使所述移动终端的基带处理器接收多个转化为对应光强度的数字信息，根据所述多个转化为对应光强度的数字信息计算得到当前光强度变化情况；判断所述当前光强度变化的情况是否属于对应将屏幕解锁的第一模式，若是则将屏幕解锁，其中，所述第一模式为：所述当前光强度变化为光强度由初始值增大直到一最大值，再由最大值变为初始值，其中光强度由初始值到最大值的时间为T1，由最大值变为初始值的时间为T2，且T1大于两倍T2；或判断所述当前光强度变化的情况是否属于对应放弃解锁屏幕的第二模式，若是则放弃解锁屏幕，其中，所述第二模式为：所述当前光强度变化为光强度由初始值增大直到一最大值，再由最大值变为初始值，其中光强度由初始值到最大值的时间为T1，由最大值变为初始值的时间为T2，且T1小于两倍T2。
其中，所述在屏幕被锁状态下，使红外接收管接收来自红外发射管发射的红外光之前还包括：接收来自移动终端的操作，点亮处于锁屏状态的移动终端屏幕。
为解决上述技术问题，本发明采用的另一个技术方案是：提供一种屏幕解锁系统，包括：红外光发射模块，用于发射红外光；红外光接收模块，用于接收红外光发射模块发射而被反射回来的红外光；检测模块，用于先后在预定时间内检测红外光接收模块接收的多个红外光强度，并把所述光强度转化为数字信息发送；处理模块，用于接收来自检测模块的多个转化为对应光强度的数字信息，根据所述多个转化为对应光强度的数字信息计算得到当前光强度变化情况；判断控制模块，用于判断所述当前光强度是否属于对应将屏幕解锁的第一模式，若是则将屏幕解锁。
其中，所述系统包括：设置模块，用于设置第一模式，所述第一模式为所述当前光强度变化为光强度由初始值增大直到一最大值，再由最大值变为初始值，其中光强度由初始值到最大值的时间为T1，由最大值变为初始值的时间为T2，且T1大于两倍T2；或用于设置第二模式，所述第二模式为当前光强度变化为光强度由初始值增大直到一最大值，再由最大值变为初始值，其中光强度由初始值到最大值的时间为T1，由最大值变为初始值的时间为T2，且T1小于两倍T2。

其中，所述判断控制模块还用于判断所述当前光强度是否属于对应放弃解锁屏幕的第二模式，若是则放弃解锁屏幕。
为了解决上述技术问题，本发明的还有一技术方案是：提供一种移动终端，包括上述的屏幕解锁系统。
本发明的有益效果是：区别于现有技术的情况，本发明使用接近传感器对手势的识别进而实现屏幕的解锁控制。通过该方式不需要直接接触移动终端屏幕或按压移动终端键盘就能实现解锁，在一定程度上保护移动终端屏幕和键盘，延长键盘和屏幕的使用寿命，并且不会弄脏移动设备的屏幕和键盘。另外，该方式简单易实现，成本低，同时也能提升用户体验。

图7是 本发明屏幕解锁系统一实施例的原理框图；
图8是 本发明移动终端一实施例的具体应用电路图。
【具体实施方式】
请参阅图1，本发明屏幕解锁方法一实施例包括：
步骤S101：使移动终端的红外接收管接收来自红外发射管发射而被反射回来的红外光；
移动终端响应用户的按键操作，点亮处于锁屏状态的屏幕。此时，在移动终端处于锁屏状态的情况下，使移动终端内的红外接收管接收红外发射管发射而反射回来的红外光。在实际应用中，当有物体靠近接近传感器时，红外发射管发射的红外光被物体反射而由红外接收管接收。当没有物体靠近时，红外接收管接收不到红外发射管发出的红外光。通常红外发射管和红外接收管之间设置一个挡墙，以防止红外发射管发射出的红外光不经过反射而直接被红外接收管接收；
步骤S102：使移动终端的接近传感器先后检测得到预定时间内的多个红外光强度，并把光强度转化为数字信息发送给移动终端的基带处理器；
移动终端的接近传感器实时监测红外接收管接收红外光的情况，在红外接收管接收到红外光时，接近传感器先后检测得到预定时间内的多个红外光强度，并把光强度转化为移动终端的基带处理器能够识别的数字信息，再发送给基带处理器处理；
步骤S103：使移动终端的基带处理器接收多个转化为对应光强度的数字信息，并计算得到当前光强度变化情况；
基带处理器对接收到的多个转化为对应光强度的数字信息，并计算得到当前光强度变化情况。比如当物体由远到近靠近接近传感器检测区域时，接近传感器检测得到红外光强度数据从D(0)渐变到D(max)，其中D表示光强度，基带处理器计算得到当前光强度为D(0)渐变到D(max)。在一具体应用中，设置红外接收管在预定时间比如10秒内对光强度采样十次，并取其平均值，例如D(0)=(S(0)+S(1)+…+S(9))/10，S表示取样的光强度值；如果D(n)>=D(n-1)，接收到的红外光强度递增，表明物体正在靠近传感器检测区域；如果D(n)不再增加，即达到D(max)，表明物体已经接触到传感器检测区域；如果D(max)又渐变到D(0)，表明物体正远离传感器检测区域；
步骤S104：判断当前光强度变化的情况是否属于对应将屏幕解锁的第一模式，若是将屏幕解锁；
通过判断基带处理器得到的当前光强度变化的情况是否属于对应将屏幕解锁的第一模式，如果是则将屏幕解锁。其中，在一个具体应用中，这里的第一模式为：当前光强度变化为光强度由初始值增大直到一最大值，再由最大值变为初始值，其中光强度由初始值到最大值的时间为T1，由最大值变为初始值的时间为T2，且T1大于两倍T2。如果当前光强度变化的情况不属于对应将屏幕解锁的第一模式，则判断当前光强度变化的情况是否属于放弃屏幕解锁的第二模式。其中，第二模式为：当前光强度变化为光强度由初始值增大直到一最大值，再由最大值变为初始值，其中光强度由初始值到最大值的时间为T1，由最大值变为初始值的时间为T2，且T1小于两倍T2。
当然，还可以将第一模式、第二模式分别设定为其他模式，本发明不作限定。
请参阅图2，为本发明屏幕解锁方法一实施例的接近传感器检测红外光强度的示意图，如图所示：红外发射管201发射红外光，红外接收管202接收红外光，接近传感器203检测并计算红外接收管202接收到的红外光强度。只有当有物体204靠近接近传感器203时，红外发射管201发射的红外光才被物体204发射，红外接收管202才能接收到红外光。而没有物体204靠近时，红外接收管202接收不到红外发射管发出的红外光。通常红外发射管201和红外接收管202之间还会设置一个挡墙205，以防止红外发射管201发射出的红外光过多的在手机内部绕射干扰红外接收管202。通过接收到的红外光强度变化，可以实现对物体204靠近与否的判断和识别。
请参阅图3，为本发明屏幕解锁方法一实施例的具体应用示意图，图4为对应该具体应用的接近传感器检测到的红外光强度变化示意图。如图所示，当手指302由远到近按到接近传感器301检测区域时，接近传感器301检测得到红外光强度数据从D(0)渐变到D(max)(如图4所示)，此检测过程耗时T1，其中D表示光强度；在一具体应用中，设置红外接收管在预定时间比如10秒内对光强度采样十次，并取其平均值，例如D(0)=(S(0)+S(1)+…+S(9))/10，S表示取样的光强度值；如果D(n)>=D(n-1)表明手指302正在靠近传感器检测区域；如果D(n)不再增加，即达到D(max)，表明手指302已经接触到传感器检测区域，T1为从手指302开始靠近到接触接近传感器301感应区域所用的时间。手指302接触到接近传感器301检测区域后，所持续的时间为T，即贴近保持时间。手指302由接触接近传感器301检测区域的位置平行划出，接近传感器301检测到的红外光强度由D(max)迅速变小到D(0)，此检测过程耗时为T2；如果T1时间大于两倍T2时间，判断为解锁动作，控制解锁屏幕。
请参阅图5，为本发明屏幕解锁方法一实施例的另一具体应用示意图，图6为对应该具体应用的接近传感器检测到的红外光强度变化示意图。如图所示，当手指502由远到近按到接近传感器501检测区域时，接近传感器501检测得到红外光强度数据从D(0)渐变到D(max)(如图6所示)，此检测过程耗时T1，其中D表示光强度；在一具体应用中，设置红外接收管在预定时间比如10秒内对光强度采样十次，并取其平均值。例如D(0)=(S(0)+S(1)+…+S(9))/10，S表示取样的光强度值；如果D(n)>=D(n-1)表明手指502正在靠近传感器检测区域；如果D(n)不再增加，即达到D(max)，表明手指502已经接触到接近传感器501检测区域，T1为从手指502开始靠近到接触到接近传感器501感应区域所用的时间。手指502接触到接近传感器501检测区域后，所持续的时间为T，即贴近保持时间。T时间结束后，手指502由接触接近传感器501检测区域的位置垂直离开，接近传感器501检测到的红外光强度由D(max)逐渐变小到D(0)，大概与垂直靠近的强度变化曲线相反，此检测过程耗时为T2；如果T1时间小于两倍T2时间，判断为放弃解锁动作。

其中，基带处理器11负责系统控制，通过I2C接口分别与红外接收管13以及传感器14通讯，用于接收来自传感器14的多个转化为对应光强度的数字信息，由该数字信息计算得到当前光强度变化情况，并根据光强度变化情况识别动作，控制屏幕解锁状态。红外LED12通过GPIO接口与基带处理器11连接，用于发射红外光。红外接收管13接收红外光。传感器14检测红外接收管13接收的红外光强度并将红外光强度转化为数字信息发送给基带处理器11。
