具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
为了便于理解，下面对本申请中出现的名词进行说明。
第一模式，包括所述电子设备的睡眠模式、低电量状态或空闲状态。
空闲状态，是指电子设备处于非使用状态。对于该状态的判断可以是电子设备结合用户的睡眠相关数据进行判断。例如，电子设备获取用户的睡眠数据，用户的睡眠数据可以包括心跳频率或血压等数据，根据这些数据判断用户是否处于睡眠状态，当判断用户处于睡眠状态时，则确定自身处于空闲状态。或者，电子设备获取关于自身状态的数据进行判断。例如，电子设备的位置数据、灭屏时间等数据。若位置数据在预设时间内保持不变，且灭屏时间达到预设时长，则判断电子设备处于非使用状态。此外，在一些实施例中，电子设备还可以将测量移动数据的传感器数据、光传感器、灭屏时间、以及当前系统时间等结合来判断用户可能处于睡眠状态，即表明手机为空闲状态。
初始电量，是指手机进入空闲状态时进行初始化，获得的电池的电量。
掉电量，初始电量减去当前电量的差值，或者，将电量按照获取时间先后进行排序，预设时间段(第二预设时长)内的起点时刻(第二时刻)对应的电量减去当前电量的差值。其中，初始电量表示电子设备进入第一模式时的第一时刻获取的电量，第一时刻为电子设备进入第一模式的起始时刻。第二时刻为在第二预设时长内的起点时刻，第二预设时长为存储的电量记录的时长。
通信次数，是指当前在后台运行的所有进程，从电子设备开机完成开始统计的与其他设备通信次数的总和。
通信次数的变化次数，是相对于在第二预设时长内的第二时刻对应的通信次数所增加的通信次数，即，当前通信次数减去所述第二时刻对应的通信次数得到所述通信次数的变化次数。其中，第二预设时长的第二时刻(起点时刻)可以是电子设备进入第一模式时的第一时刻，也可以是在第一时刻之后的某一时刻。
下面结合具体场景对本申请的技术方案进行描述。
参考图1，图1示出了手机处于空闲状态时的场景图。该场景图中包括手机101，基站102和用户103。其中，手机101和基站102正在通信，而用户在睡眠状态中。手机101获取到一定量的用户有关的睡眠数据，例如，心跳频率、血压、呼吸频率、眼球转动快慢等数据。这些数据可以是通过用户佩戴的穿戴设备，例如，通过佩戴手表获得，手表将这些数据传输给手机101.手机基于这些睡眠相关的数据判断用户处于睡眠状态，即手机判断自身处于空闲状态。此时手机进行系统初始化，记录进入空闲状态时的系统时刻，该系统时刻对应的电池的初始电量，以及后台未关闭应用程序的进程的通信次数。并在此之后不断地获得电池的电量以及应用或进程与基站102的通信次数，并基于持续获得的电池的电 量(当前电量)和进入空闲状态时的电池的电量(初始电量)计算出掉电量(当前电量-初始电量)，或者基于当前电量减去预设时间(第二预设时长)内的起点时刻获得的电量计算出掉电量(当前电量-预设时间内的起点时刻获得的电量)。当掉电量超过预设电量阈值10％，则进一步判断后台进程的通信次数是否超过预设通信次数50次。当后台进程的通信次数超过50次，则手机关闭网络通信连接，断开与基站102通信。从而在用户处于睡眠状态中(第一模式)，阻止后台进程通信，避免后台进程因通信而导致电子设备的电量下降的问题，影响用户的体验。
在本申请的一些实施例中，当用户的睡眠数据不足以判断用户处于睡眠中时，手机101还可以通过手机测量自身是否移动的数据、接收光线的强度、灭屏时间等数据判断手机为空闲状态。此处为示例性说明手机空闲状态的判断，并不作为对本申请的限定。
需要说明的是，本申请的技术方案应用的场景不局限于用户处于睡眠状态，还可以是手机的电量低于预设阈值，或者手机进入睡眠模式，或其他用户非使用状态等场景，此处并不作限定。
在本申请的一些实施例中，手机还可以根据第一预设时长内的掉电量和通信次数来判断是否关闭网络通信连接，即通过掉电的速度和通信次数的频率来确定是否关闭网络通信连接。例如，在20分钟之内，掉电量超过10％，且后台进程的通信次数达到50次。则手机101判断进程为频繁通信，电量急剧消耗，则关闭网络通信连接。避免后台进程因频繁通信而导致电子设备的电量急剧下降的问题，影响用户的体验。
上述描述中以手机为电子设备举例进行说明，本申请中的电子设备可以是平板电脑、笔记本电脑、超级移动个人计算机、个人数字助理(personal digital assistant，PDA)、电视，或者可穿戴的电子设备，如手表、手环等。本申请中对电子设备的设备类型不予具体限定。
下面结合附图对本申请的技术方案进行详细的描述。
示例性的，图2a为本申请实施例提供的一种电子设备的结构示意图。该电子设备100可以包括处理器110，外部存储器接口120，内部存储器121，通用串行总线(universal serial bus，USB)接口130，充电管理模块140，电源管理模块141，电池142，天线1，天线2，移动通信模块150，无线通信模块160，音频模块170，扬声器170A，受话器170B，麦克风170C，耳机接口170D，传感器模块180，按键190，马达191，指示器192，摄像头193，显示屏194，以及用户标识模块(subscriber identification module，SIM)卡接口195等。其中传感器模块180可以包括压力传感器180A，陀螺仪传感器180B，气压传感器180C，磁传感器180D，加速度传感器180E，距离传感器180F，接近光传感器180G，指纹传感器180H，温度传感器180J，触摸传感器180K，环境光传感器180L，骨传导传感器180M等。
可以理解的是，本发明实施例示意的结构并不构成对电子设备100的具体限定。在本申请另一些实施例中，电子设备100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
处理器110可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110 中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从所述存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
在本申请的一个实施例中，处理器110在判断电子设备进入空闲状态时，进行初始化，记录进入空闲状态时的电池的初始电量，以及在初始化过程中，后台未关闭应用程序或进程的通信次数。并在此之后，基于安卓的广播播报不断地获得电池的当前电量以及进程的当前通信次数，并基于持续获得的电池的电量(当前电量)和进入休眠状态时的电池的电量(初始电量)计算出掉电量(当前电量-初始电量)，或者基于预设时间内的起点时刻获得的电量减去当前电量计算出掉电量(当前电量-预设时间内的起点时刻获得的电量)。当掉电量超过预设电量阈值，例如，掉电量超过10％，则进一步判断后台进程的通信次数是否超过预设次数，例如，50次。当后台进程的通信次数超过50次，则处理器110关闭网络通信连接。从而该方法能够在电子设备100处于空闲状态等状态时，阻止后台进程通信，避免后台进程因通信而导致电子设备的电量下降的问题，影响用户的体验。
在一些实施例中，处理器110可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。
I2C接口是一种双向同步串行总线，包括一根串行数据线(serial data line，SDA)和一根串行时钟线(derail clock line，SCL)。在一些实施例中，处理器110可以包含多组I2C总线。处理器110可以通过不同的I2C总线接口分别耦合触摸传感器180K，充电器，闪光灯，摄像头193等。例如：处理器110可以通过I2C接口耦合触摸传感器180K，使处理器110与触摸传感器180K通过I2C总线接口通信，实现电子设备100的触摸功能。
在一些实施例中，通过触摸传感器180K接收到用户输入的触摸信息，例如用户通过电子设备界面设定电池电量的管理模式，可以通过点击界面上的电量管理应用程序进行设置。触摸传感器将用户点击电量管理应用程序的位置坐标信息发送给处理器110，处理器110根据位置坐标信息等确定该触摸操作为打开点击管理应用程序，并执行打开电量管理应用程序，以便于用户可以通过触摸操作实现各种功能需求。

下面结合软件、硬件的架构图，对本申请的系统功耗控制方法进行描述。
电子设备100的软件系统可以采用分层架构，事件驱动架构，微核架构，微服务架构，或云架构。本发明实施例以分层架构的Android系统为例，示例性说明电子设备100的软件结构。
示例性的，图2b为包括软件结构和硬件结构的架构图。如图2b所示，将Android系统分为四层，从上至下分别为应用程序层，应用程序框架层，安卓运行时(Android runtime)和系统库，以及内核层。
应用程序层可以包括一系列应用程序包。
如图2b所示，应用程序包可以包括相机、图库、日历、地图、WLAN、蓝牙、短信息、电量管理应用和广播接收器等。
电量管理应用，用于提供用户输入预设参数的通道。用户可以通过电源管理应用设置关于电量管理的各个参数，例如，掉电量的设定阈值、后台进程的通信次数的预设次数，以及反应电量消耗和通信频次的时间参数等。
广播接收器用于响应来自其他应用程序或者系统的广播消息。例如，当应用程序通过在Android Manifest.xml中注册广播接收器来监听电池的电量，后台进程的通信次数等。
应用程序框架层为应用程序层的应用程序提供应用编程接口(application  programming interface，API)和编程框架。应用程序框架层包括一些预先定义的函数。
如图2b所示，应用程序框架层可以包括窗口管理器、内容提供器、电话管理器、资源管理器、数据分析模块、执行模块等。
窗口管理器用于管理窗口程序。窗口管理器可以获取显示屏大小，判断是否有状态栏，锁定屏幕，截取屏幕等。
内容提供器用来存放和获取数据，并使这些数据可以被应用程序访问。所述数据可以包括视频，图像，音频，拨打和接听的电话，浏览历史和书签，电话簿等。
电话管理器用于提供电子设备100的通信功能。例如通话状态的管理(包括接通，挂断等)。
资源管理器为应用程序提供各种资源，比如本地化字符串，图标，图片，布局文件，视频文件等等。
在本申请的一个实施例中，数据分析模块用于根据功耗的各类参数信息分析当前是否对电子设备的功耗进行管控。
执行模块用于根据数据分析模块的指令，控制硬件层的硬件执行相应的动作，例如，关闭通信开关，以控制电子设备因通信造成的功耗。
如图2b所示，内核层是硬件和软件之间的层。内核层可以包括传感器驱动、电量计驱动、射频收发器驱动、通信开关驱动，这些驱动作为软件模块与硬件之间的通信桥梁，实现软硬件之间的通信。其中电量计驱动用于驱动电量计对电池的电量进行监测，并向系统发送监测结果，由系统对该结果进行播报，以使广播接收器获得对应的电池电量。射频收发器驱动用于射频收发器统计通信次数，并向系统发送统计结果，由系统对该结果进行播报，以使广播接收器获得对应的进程的通信次数。
硬件层包括执行各种指令的硬件，如图2b所示，可以包括数据存储区、电量计、电池、射频收发器和通信开关和光传感器等，
光传感器用于获取外界光的相关数据。光传感器可以包括如图1所示的环境光传感器和接近光传感器。环境光传感器可以获取环境的光线亮度、光线强度等，接近光传感器可以获取周围物体反射的红外反射光的数据。光传感器获取到外界光的相关数据，并将这些数据通过传感器驱动发送给数据分析模块。数据分析模块对这些数据进行分析判断，以确定当前电子设备是否处于夜间或背包内(通常理解为非用户使用时间段，电子设备为空闲状态)。
当数据分析模块判断电子设备处于空闲状态时，数据分析模块向执行模块发送电子设备为监测功耗的指令，执行模块基于该指令通过电量计驱动使电量计监测电池的电量。执行模块通过射频发射器驱动使射频发射器记录通信次数。这些数据在硬件层被获取，并通过对应的驱动写到设备节点(写到内存的指定文件内)，并通过系统播报方式被应用层的广播接收器获得。其中，关于广播接收器接收硬件层的数据的实现过程。以电量数据为例，对于上层安卓安装包(Android Package kits，APK)，需要注册安卓动作意图电量变化(android intent action Battery-changed)广播。当电量变化时，框架层会遍历所有注册此广播的广播接收器，系统广播向注册过的广播接收器发送电量的变化信息，从而接收到电量。此外，本申请的其他的数据，也可以通过广播接收器获得，例如，位置数据，灭屏时间，系统时间等，这些数据被硬件层各自的传感器采集，传感器将模拟信号转化为数字信号，通过对应的驱动写到设备节点，通过安卓广播将这些数据发送给注册的广播接 收器。以实现底层数据到应用层的过程。
如图2b所示，当电量计将获得的系统时刻、初始电量、以及持续监测的当前电量时，将这些数据以记录表的形式存储到数据存储区，射频发射器将获得通信次数存储到对应的记录表中。在数据存储区可以将上述数据以哈希表形式存储，便于快速的查询。
广播接收器将接收的当前电量和当前通信次数发送给数据分析模块。数据分析模块基于接收的当前电量和存储在数据存储区内的初始电量，或预设时间内的起点时刻对应的电量，计算出掉电量，并将掉电量与预设阈值(可以从电量管理应用获得或系统默认值)进行比较。当掉电量大于等于预设阈值，例如10％，则进一步判断当前通信次数是否大于等于预设次数(可以从电量管理应用获得或系统默认值)。若是，数据分析模块向执行模块发送管控指令。例如，关闭网络的指令，执行模块执行该指令，并通过通信开关驱动关闭通信开关，即为电子设备断网，使射频收发器停止信号接收和发送。从而实现在手机处于空闲状态时(即用户不使用电子设备时)，减少电池的电量的消耗，提高用户体验。
下面结合具体实施例对本申请实施例的系统功耗控制方法进行描述。
本申请的系统功耗控制方法可以应用于上述图2a和图2b描述的电子设备中，在下面的实施例中以手机作为电子设备进行了说明。
参考图3，图3示例性示出了系统功耗控制方法的流程图。如图3所示，该流程图包括S300～S308。
在S300，手机确定自身处于空闲状态。
在本申请的一个实施例中，空闲状态可以包括以下几种方式中的一种或多种进行判断。
第一种，手机可以通过自身的环境光传感器和接近光传感器检测环境光亮度、光线强度、以及红外线反射光等参数判断当前自身是否处于夜间。该步骤如上述图1中环境光传感器、接近光传感器和处理器执行。若处于夜间，进一步判断手机的屏幕黑屏的时间是否超过设定时间，例如，超过1分钟，若是，则确定自身处于空闲状态。
第二种，手机可以通过系统时间来判断当前是否处于夜间。例如，当系统时间到达晚上10点，属于夜间时间。此外，手机可以通过用户设定的模式判断当前是否处于夜间。例如，手机设有夜间模式和白天模式，当用户将手机设定为夜间模式时，则手机确定当前处于夜间。进一步判断手机的屏幕黑屏的时间是否超过设定时间，例如，超过1分钟，若是，则确定自身处于空闲状态。
第三种，手机可以结合用户数据进行判断。例如，用户佩戴的手表监测到用户的心跳频率或血压等数据，基于这些用户数据判断该用户处于睡眠状态。则可以判断当前手机为空闲状态。通过用户数据可以在任何时间对用户是否处于睡眠中。并预测手机处于空闲状态。
在本申请的一些实施例中，手机可以将上述三种中的多种数据进行结合来判断自身是否处于空闲状态，以提高判断的准确性。此处只是示例性说明，也可以结合其他数据判断手机为空闲状态，例如，可以结合手机是否在充电等数据进行判断，此处并不作为限定。
上述描述中以空闲状态作为手机的第一模式进行的说明，本申请的一些实施例中，第一模式还可以是电量值较低，或者手机进入睡眠模式等，此处并不作为限定。
S301，手机获取进入空闲状态时的系统时刻和初始电量。
当手机进入空闲状态时，作为对电量管控判断的时机，手机通过执行系统初始化，获取的系统时刻和初始电量，并作为原始记录存储在内部存储器内。
S302，手机在处于空闲状态时间内不断监听的电量和后台进程的通信次数，并将每一次监测到的电量和通信次数进行存储。例如，可以通过系统广播播报电量、系统时刻、通信次数等信息，由广播接收器监听并获得电量、系统时刻、通信次数等。以使手机的其他程序可以进一步对这些数据进行分析处理。
在本申请的实施例中，通信次数是指后台所有进程与外界通信的总和。这些数据被以哈希表的形式存储，便于手机能够快速的获取到表中指定的数据。当哈希表中的数据超过设定值时，则按照记录时间的先后顺序将排列在前的电量记录进行删除。
在本申请的一些实施例中，手机还可以对后台的每一个进程赋予标识，并根据标识确定每一个进程的通信次数。对每一个进程的通信进程分别进行记录，以便于对单个进程的通行情况进行管控。
S303，手机计算掉电量。
在本申请的实施例中，手机将初始电量减去当前电量得到掉电量。或者可以将记录表中的起始时刻的电量减掉当前电量，从而可以及时去除参考价值低的电量，释放内存。
如图4所示的电量变化图，如图4所示，Q1作为初始电量99％，在时间t1获得的电量Q2为95％，则在t1时间的掉电量＝Q1-Q2，即从t0到t1间隔15分钟，掉电量为99％-95％＝4％。Q3为在时间t2获得的电量89％。在t2时间的掉电量＝Q1-Q3，即从t1到t2间隔20分钟，掉电量为99％-89％＝10％。在本申请中，当获取电量时通过系统播报的方式，即当电量发生变化时获得电量，则每两个电量对应的获取时间间隔并不一定相同。例如，在t0到t1的时间间隔为15分钟，而在t1到t2的时间间隔为20分钟。若采用周期性监测电量的方式时，时间间隔可以设定为固定值，例如15分钟。
S304，手机判断掉电量是否达到设定阈值。举例说明，结合图4所示，若设定阈值为10％，当前电量为95％，则掉电量4％，未达到10％。则手机返回执行S302。
当前电量为89％，则掉电量为10％，达到10％，则手机执行S305，读取后台进程的通信次数。其中，通信次数为手机后台所有进程通信次数的总和。
S306，手机判断通信次数是否达到预设通信次数。
在本申请的一个实施例中，该通信次数是指，在当前时刻，手机后台运行的所有进程从手机开机完成的起点时刻开始统计的，与其他设备通信次数的总和。
例如，预设次数为50次。当前后台进程通信次数为40次，未达到设定次数。则手机继续执行S305。其中通信次数可以是后台进程运行的总的通信次数。
若当前后台进程通信次数为60次，超过预设次数50次，则手机执行S307，手机对电量的消耗进行管控。例如，通过控制网络通信开关，使手机断开网络通信连接。
根据本申请实施例的系统功耗控制方法，可以避免在手机处于空闲状态时(非用户使用状态)，手机后台进程通信次数较多，而使电量被消耗，影响用户体验。
在一些实施例中，还可以对后台运行的每一个进程的通信次数进行限定。例如，对后台的每一个进程分别计算各自的通信次数，例如，进程通过调用上层接口，并读取到设备节点中的数据，并获得各自的电量、通信次数等数据。当其中一个进程的通信次数达到设定值，例如20次，则手机可以单独对该进程进行管理，例如，关闭该指定进程。
在本申请的另一个实施例中，还可以对掉电量的速度和通信的频次进行限定。即将预设时间内的掉电量和通信次数作为判断条件，可以避免短时间内电量急剧消耗的情况。
参考图5，图5示例性示出了系统功耗控制方法的另一流程图。该方法可以由具有上 述图1和图2中所示结构的手机执行。如图5所示，该流程图包括S500～S508。
其中，S500～S501与上述图3中S300～S301相同，S503～S504与上述图3中S303～S304相同，具体可参考上述实施例中的描述，此处不再赘述。
在S502中，手机在空闲状态时不断监听电池的电量以及对应的时间戳、监测后台进程的通信次数以及对应的时间戳，并存储。手机在周期检测的电池的电量时，同时记录每一条电量记录对应的时间戳。并且在每一次记录通信次数时，同时记录每一条通信次数的对应的时间戳。
在S505中，读取后台进程的当前通信次数，并获取预设时长(第二预设时长)内的起点时刻对应的通信次数与当前通信次数的差值(通信次数的变化数量)。例如，获取记录中的在第二预设时长，例如20分钟内的起点时刻对应的进程的通信次数20次的记录，而当前时刻获得通信次数为80次，则通信次数的变化数量为60次。通过设定第二预设时长，可以避免由于时间过长，在先的获取的记录的参考意义降低，因此，通过设定预设时长，定期对记录中时间较早的记录删除，提高电子设备对耗电情况判断的可靠性。
在S506中，手机判断通信次数的变化次数是否达到预设变化次数。例如，预设变化次数是50次，当通信次数变化的数量为60次，则大于50次，则执行在S507。否则，手机执行S505。
在S507，手机判断是否在预设时长(第一预设时长)内掉电量达到预设电量阈值，且通信次数的变化数量达到设定变化次数。例如，第一预设时长为10分钟，即在10分钟内，若掉电量达到设定阈值10％，且通信次数达到设定次数50次，则手机执行S508，手机对电量的消耗进行管控。该方法通过在预设时长内判断掉电量达到预设阈值和通信次数的变化次数达到预设变化次数，可以有效的避免在较短时间内，因手机耗电速度较快，而导致电量消耗过快。因此，当发生短时间内掉电量过快时，需要及时对手机进行管控，例如，通过控制通信开关，使手机断开网络通信连接。通过三个因数的结合判断，可以提高电量管控的谨慎性，避免因切断网络而给用户带来不便。
需要说明的是，在判断掉电量和通信次数的变化次数时，设置的第一预设时长应小于电量记录和通信次数记录的第二预设时长，以使得在S507中，具有足够时长内的电量记录和通信记录，确保判断的准确性。
当在S507中，判断结果为否，即未在预设时长内掉电量达到设定阈值，且通信次数的变化次数达到设定变化次数，手机返回执行S502。
根据本申请实施例的系统功耗控制方法，能够在手机处于非使用的状态下、睡眠状态或低电量等情况下，手机通过控制后台进程的通信，避免电子设备的电量被急剧消耗，确保电子设备的使用时长，进一步提高用户体验。
在本申请的实施例中，当手机检测用户的操作，例如，点击后的亮屏、移动等操作时，则判断当前处于被用户使用的状态，则恢复网络，以便于用户可以正常使用网络，提高用户体验。
在本申请的一些实施例中，上述图3和图5中提及的预设阈值和预设次数、设定时长等参数可以是系统默认值，也可以是用户根据需要进行设定。
参考图6，图6示例性示出了手机的界面操作示意图。如图6中的(a)所示，该界面610上显示有电量管理图标611。用户可以通过打开图标611对掉电量的预设阈值和通信次数的预设次数等参数进行设定。当用户点击图标611，可进入用户设置界面。如图6中 的(b)所示，界面620为用户设置界面，该界面620包括用于参数设定的选项，用户通过这些攒想对各参数进行设定，例如，“设定管理时间”、“设置电量的预设阈值”、“设置通信次数的预设次数”和“设置预设时长”。当用户点击设置电量的预设阈值，如图6中的(c)所示，进入界面630,630包括掉电量的预设阈值的设定尺631，用户可以通过设定尺631选择预设电量阈值的参数值。此外，用户还可以通过界面620上的设定管理时间需要管理的时间段，例如，晚上10点到次日凌晨5点。通过设置通信次数的预设次数设定通信次数的预设次数或者预设变化次数等。用户还可以通过设置预设时长选项对第一预设时长进行设定。本申请采用用户自定义设定方式可以提高用户使用的灵活性，不同用户可根据不同需求选择适当的参数，有利于提高用户体验。
