Description

终端功耗的控制方法及装置、终端 技术领域
本发明涉及通信领域,具体而言,涉及一种终端功耗的控制方法及装置、终端。
背景技术
如今的智能手机越来越普及,基本上所有的智能手机上都配备有一大票传感器,也就是本领域技术人员统称的Sensor,比如距离传感器、光线传感器、陀螺仪等等。一代又一代的传感器消耗的功率都在不断下降。这就让手机具备了实时检测更多所谓的环境状态信息的可能性,也就是说,不管手机是在工作还是在待机,连续读取诸如加速度、指向、坐标、温度、气压、磁场等环境数据的传感器所消耗的能量成本接近为0,这使得智能手机的应用前景更加广阔。
虽然传感器本身消耗的功率很小,但是如果这些传感器长期开着手机的电量消耗仍然会很可观,这是由于传统的手机中央处理器(Central Processing Unit,简称CPU)内核在进入深度待机模式的时候其实是完全不工作的,甚至连核心供电都会被切断。因此如果直接靠主CPU来读取传感器的数据,在深度待机时,手机的主CPU就无法读取传感器。反过来说,如果主CPU想要不断读取并处理传感器数据,***就永远无法进入深度待机,电池自然也不能持续工作很长时间。
为此,相关技术中出现了一种名为传感器中枢(Sensor Hub)的技术,Sensor Hub技术的意义就在于,用一个较低性能、超低功耗的Hub(协处理器芯片),为手机提供一个完整的、监控所有***传感器并且可以进行初级数据加工的解决方案。也就是说汇集尽可能多的传感器到这个Hub上,让它取代主CPU来控制所有的传感器并处理各种来自传感器的数据(主要是用来处理一些小数据运算),然后在需要主CPU介入的时候(例如大数据运算时)才将其自深度待机模式中唤醒。这样主CPU可以随时随地进入深度待机状态,藉此***功耗大大降低,但又可以使得传感器一直打开。随着智能手机的普及以及手机应用的不断丰富,越来越多的人每天会花费较长的时间盯着手机进行玩游戏、上网、看视频等等操作,但长时间看手机时会感觉眼睛酸痛或被事件打断,此时眼睛已经离开屏幕了,但应用可能没有及时被关闭又忘记锁屏,又或是频繁进行锁屏解锁操作,造成了不必要的电量浪费。
针对相关技术中,尚无一种能够根据终端的使用者的状态对终端进行功耗控制进而导致终端耗电过快的技术方案的问题,尚未提出有效的解决方案。

为了更好的理解上述基于协处理器对终端功耗进行控制的过程,以下结合以下过程对本发明实施例上述提供的技术方案进行说明:
本发明实施例所提供的终端配备了多种传感器,其中包括可以检测人面部和眼睛活动状态的传感器,由于该终端上配备了Sensor Hub协处理器,所有的传感器被Sensor Hub协处理器统一汇集在一起并受其控制,即Sensor Hub能够处理从传感器收集到的人面部和眼睛活动状态信息,并据此判断出当前眼睛和/或面部是否在屏幕前方或离开屏幕。
(一)当Sensor Hub判断出眼睛和/或面部离开屏幕持续一段预定时间T1(T1>0)后,由传感器中枢Sensor Hub直接对显示模块进行控制,以降低屏幕功耗,具体控制为:
1)按一个预定值降低屏幕亮度;
2)按一个预定值降低屏幕分辨率;
3)按一个预定值让屏幕灰阶显示。
(二)当Sensor Hub判断出眼睛和/或面部离开屏幕持续一段预定时间T2(T2>T1)后,由Sensor Hub直接对网络数据连接模块、各后台应用控制模块进行控制,以降低功耗,具体控制为:
1)如果当前有数据连接,则断开连接;
2)如果当前有其它后台应用,则关闭后台应用。
(三)当Sensor Hub判断出眼睛和/或面部离开屏幕持续一段预定时间T3(T3>T2>T1)后,由Sensor Hub直接对显示模块进行控制,以降低屏幕功耗,具体控制为:
1)关闭屏幕显示,即黑屏。
(四)当Sensor Hub判断出眼睛和/或面部回到屏幕持续一段预定时间T4(T4>0)后,由Sensor Hub直接对显示模块、网络数据连接模块、各后台应用控制模块进行控制,以恢复手机到正常状态,具体控制为:
1)开启屏幕显示,恢复屏幕亮度、分辨率到正常值;
2)如果之前为了降低功耗断开了数据连接,则恢复数据连接;
3)如果之前为了降低功耗关闭了后台应用,则恢复后台应用。
采用本发明实施例提供的上述技术方案,以Sensor Hub技术为基础,在此技术之上对手机的耗电量进行了进一步的控制。由于Sensor Hub运行功耗就比主CPU低很多,所以Sensor Hub技术本身就能减少很多的电量消耗。在此基础上,又由传感器实时智能的监控用户眼睛是否盯着屏幕的状态或者用户面部是否位于终端屏幕前,并由Sensor Hub及时的对显示模块、后台应用控制模块进行功耗控制,进一步减少了这些模块的电量消耗,这两部分方案结合起来使得智能手机耗电过快的问题得以很好的解决,手机电池的续航能力能够极大的提高。
在本实施例中还提供了一种终端功耗的控制装置,应用于终端中的协处理器,用于实现上述实施例及优选实施方式,已经进行过说明的不再赘述,下面对该装置中涉及到的模块进行说明。如以下所使用的,术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现,但是硬件,或者软件和硬件的组合的实现也是可能并被构想的。图2为根据本发明实施例的终端功耗的控制装置的结构框图。如图2所示,该装置包括:
获取模块20,设置为获取终端用户的当前状态信息;
控制模块22,与获取模块20连接,设置为根据上述当前状态信息对上述终端进行功耗控制。
通过上述各个模块的综合作用,采用基于协处理器根据终端使用者的状态对终端功耗进行控制的技术手段,解决了相关技术中,尚无能够根据终端的使用者的状态对终端进行功耗控制的技术方案的问题,避免了终端不必要的电量浪费,手机电池的续航能力能够极大的提高。
可选地,获取模块20获取的上述当前状态信息包括:上述终端用户相对于上述终端的位置信息。
在本发明实施例的一个可选示例中,控制模块22,设置为当上述位置信息指示上述终端用户未处于上述终端的屏幕前时,根据上述终端用户未处于上述屏幕前的持续时间对上述终端进行功耗控制。
为了完成控制模块22的功能,如图3所示,控制模块22可以包括以下单元:第一控制单元220,设置为当上述终端用户离开时间达到第一预设时间时,控制上述终端执行以下至少之一操作:按照第一预设值降低上述屏幕亮度、按照第二预设值降低上述屏幕分辨率、按照第三预设值灰阶显示上述屏幕;第二控制单元222,与第一控制单元220连接,设置为当上述终端用户离开时间达到第二预设时间时,控制上述终端执行以下至少之一操作:关闭正在运行的应用、关闭正在运行的数据连接,其中,上述第二预设时间大于上述第一预设时间;第三控制单元224,与第二控制单元222连接,设置为当上述终端用户离开时间达到第三预设时间时,控制上述终端关闭屏幕显示功能,其中,上述第三预设时间大于上述第二预设时间。
在本发明实施例的可选示例中,当获取模块20获取的所述当前状态信息包括:终端用户的眼睛和/或面部的活动状态,其中,该活动状态用于指示眼睛对屏幕的注视状态和/或面部相对于终端屏幕的位置信息时,控制模块22还可以包括第四控制单元226,设置为根据上述位置信息判断上述终端用户处于上述终端的屏幕前的时间超过第四预设时间时,控制上述终端执行以下至少之一操作:开启屏幕显示功能、恢复初始屏幕亮度、恢复上述屏幕分辨率的初始值、恢复关闭的数据连接、恢复上述终端上关闭的应用。
