以安卓系统的电池管理为例，安卓系统的电池管理是分层实现的。最下层是硬件与驱动层面；之上在Linux内核中以JNI(Linux内核中的本地代码，以C++编写)通过SYS文件获取和传递电池的各种信息，例如状态，健康程度，容量，电压，温度等；最上层是安卓框架层面的电池服务，主要获取底层的电池事件，及时更改电池显示，报警，执行低电或过热状态下的关机保护等。
如图3，图3为一种电池管理示意图，它们的层级关系可以用图3表示。图4为一种电池管理流程示意图。
同样以安卓系统的电池管理为例，当硬件层面发生事件源，如低电，高温，插拔USB(Universal Serial Bus，通用串行总线)，电量发生变化时，产生中断并向上层安卓上报事件，同时，Linux内核层面将当前的电池信息，如工作在USB模式，充电模式，电池模式，当前的电压，电流，温度等通过SYS文件上报给安卓层面，这样，安卓层面就能够根据事件类型以及最新的电池信息作出正确的处理。
所传递的电池信息可以包括如下字段：
#define AC_ONLINE_PATH"/sys/class/power_supply/ac/online"AC电源连接状态
#define USB_ONLINE_PATH"/sys/class/power_supply/usb/online"USB电源连接状态
#define BATTERY_STATUS_PATH"/sys/class/power_supply/battery/status"充电状态
#define BATTERY_HEALTH_PATH"/sys/class/power_supply/battery/health"电池状态
#define BATTERY_PRESENT_PATH"/sys/class/power_supply/battery/present"使用状态
#define BATTERY_CAPACITY_PATH"/sys/class/power_supply/battery/capacity"电池电量
#define BATTERY_VOLTAGE_PATH"/sys/class/power_supply/battery/ba tt_vol"电池电压
#define BATTERY_TEMPERATURE_PATH"/sys/class/power_supply/battery/batt_temp"电池温度
#define BATTERY_TECHNOLOGY_PATH"/sys/class/power_supply/battery/technology"电池技术
当电池电量值为零时，或者电池温度过高时，上层电池服务会直接启动关机保护。而关于电池电量和电池电压的对应关系可以是驱动中的电压与电量曲线，一般是由移动终端厂商的硬件驱动开发制作。电压与电量的对应关系通常在安卓系统中的电池驱动中以数组的形式保存。
如图5所示，图5为一种电池的电压与电量对应关系示意图。图中的容量百分比可以是当前电量与电池容量的百分比。
图6为两种不同移动终端电池的电压与电量关系曲线示意图。横坐标是电量消耗的百分比，0处表示电量为100％。
由于安卓系统关机通常是根据电量的百分比为0作为触发条件的，所以当驱动中的电压与电量对应关系发生改变，对应的关机电压也会发生改变。通常终端电池的最高使用电压为4.2伏(V)，如果将高于4.2伏的电压被设置为电量百分比为0时，电池只要开机启动了安卓系统的电池服务，该服务就会广播电量为零的消息，使安卓系统立即进入低电关机的流程。
上层对于低电关机的判断通常是由电池电量百分比为0对应的电压数字作为阈值(不同终端设置值可能会不同，常常在3.5伏至3.8伏之间)，当底层电压到达电量百分比为0的电压时，则启动关机过程。
根据上述电池管理方法，本发明实施例通过在特定区域内临时修改电池的电压与电量对应关系，使特定区域内的移动终端低电关机，且离开该区域后，恢复开机。本发明实施例提供的方法不仅限于安卓系统，也适用于其他的系统。
如图7所示，图7为本发明实施例中所述的方法和装置的基本原理图。
图7中的发射装置可以是WIFI热点装置，蓝牙装置，也可以是NFC射频识别发射装置等。上述发射装置在正常的信号传输过程中，可以每隔固定 间隔，向处于信号覆盖范围内并与之连接的的终端A和终端B传输一次特定的信息，其中，该特定的信息可以是包含电压与电量对应关系的信息或者是触发切换电压与电量对应关系的信息。
以WIFI为例，介绍WIFI在数据传输中向终端发送上述特定的信息，上述特定的信息可以在连接的过程中实现。WIFI连接建立过程如下：
WIFI连接建立过程如下：
STA------------>Probe Request---------------->AP//广播自身数据
STA<------------Probe Response<-------------AP
STA------------>Authentication Request-------->AP//认证Auth类型，开放系统,共享密钥等
STA------------>Authentication Response------>AP
STA------------->Association Request------------>AP//请求与AP建立关联，从而可以进行数据交互
STA<------------Association Response<------------AP
WIFI热点向处于覆盖范围内的移动终端发送广播，终端回应后，WIFI热点进一步将自身鉴权类型发送给终端，启动鉴权，鉴权成功后进一步发起连接请求，建立数据连接，并向移动终端发送上述特定信息。
如图8所示，图8为一种WIFI热点的信令结构示意图，该结构中包含了序列控制项(frame control)，持续时间标识(duration ID)，目的地址(destination address)，资源地址(source address)，服务集标识(BSSID)，顺序控制字段(seq-ctl)，服务集标识，支持速率(support rate)，扩展支持速率(extended support rate)，校验位(FCS)。可以看出，其中并没有可以进一步加以利用的保留位，在本发明实施例中，可以在最后的校验位之前加入本发明实施例所述的第二电压与电量对应关系的数据，或者控制移动终端进行第一对应关系和第二对应关系切换的特定信号。
同样也可以在认证的过程中加入本发明实施例中所添加的信息，WIFI热点向终端发送的认证信令如图9所示，图9是另一种WIFI热点的信令结构示意图，序列控制项(frame control)，持续时间标识(duration ID)，目 的地址(destination address)，资源地址(source address)，服务集标识(BSSID)，顺序控制字段(seq-ctl)，身份验证算法编号(auth algorithm number)，身份验证(auth transaction sequence No.)，状态码(status code)，质疑文字(challenge text)，校验位(FCS)。由图可知，其中的数据位也都有特定的用途，因此同上可以在校验位之前加入新的字段，用来传输本发明实施例提出的所述的第二电压与电量对应关系的数据，或者控制移动终端进行第一对应关系和第二对应关系切换的特定信息。
若上述发射装置为NFC射频识别装置，可以在移动终端靠近NFC装置，进行识别时，进行数据传输，向移动终端发送上述特定信息。
如图10所示，图10为本发明实施例提供的一种移动终端关机的方法的举例。
该方法包括以下步骤：
步骤1001、检测是否存在信号发射的信号源，该信号源可以是蓝牙、WIFI、NFC等发射装置发送的。
步骤1002、检测接收到的信号中是否包含切换电压与电量对应关系的特定触发信息。
如果搜索到相关的信号源后，对其进行逐个轮询，检查接收到的信号中是否包含切换当前电池使用的电压与电量对应关系的的信息。
步骤1003、若接收到上述信息，判断电池中除当前电压与电量的第一对应关系外是否还存在用于切换的第二对应关系，若存在上述第二对应关系，可以在电池驱动中将当前电量与电压的第一对应关系切换为第二对应关系；若不存在上述第二对应关系，则不切换电压与电量对应关系。
步骤1004、终端根据上述第二对应关系和电压值，确定当前电量为关机电量。
步骤1005、终端启动低电关机。在移动终端关机后，与普通关机不同的是，本发明实施例所述的由于电压与电量对应关系改变而导致低电关机后，终端仍然保持对于发射装置连接部分的模块供电，使之保持对上述连接的检测以及对信号的检测。
步骤1006、若检测到断开连接或者不能检测到信号，此时移动终端可能离开上述信号覆盖区域，终端恢复原有的电压与电量第一对应关系，按照上述电压与电量第一对应关系重新确定电量不为关机电量后，触发开机。
另外，在发射装置信号覆盖范围之外的移动终端，由于无法接收到上述包含切换电压与电量对应关系消息和电压与电量对应关系的特定信息，电量不受到影响。
本发明实施例也可以在检测到离开上述发射装置信号覆盖区域后，触发移动终端自动开机，恢复终端原有默认的电量管理方式，使用原有的电压电量关系曲线确定电量。上述离开发射装置信号覆盖区域可以是检测不到上述发射装置发出的信号或者是检测到与之断开连接时，为离开上述区域。
这样通过接收外部信号控制终端电量，使终端在特定区域内无法开机使用，达到保护信息私密性或者减少安全隐患的目的。
如图11所示，图11为本发明实施例提供的另一种移动终端关机的方法的举例，该方法包括以下步骤：
步骤1101、检测是否存在发射信号发射的信号源，该信号源可以是蓝牙、WIFI、NFC等发射装置发送的。
步骤1102、检测接收到的信号中是否包含电压与电量对应关系的信息。
如果搜索到相关的信号源后，对其进行逐个轮询，检测接收到的信号中是否包含电压与电量对应关系的信息。
步骤1103、移动终端接收到该信息后，将接收到的电压与电量对应关系传送给上层的电池服务，电池服务根据底层上报的电压，按照该电压与电量对应关系计算当前电量值，替换底层驱动上报的电池电量值。
步骤1104、终端根据上述接收到的电压与电量对应关系和上报的电压值，确定当前电量为关机电量。
步骤1105、终端启动低电关机。在移动终端关机后，与普通关机不同的是，本发明实施例所述的由于电压与电量对应关系改变而导致低电关机后，终端仍然保持对于发射装置连接部分的模块供电，使之保持对上述连接的检测以及对信号的检测。
步骤1106、若检测到断开连接或者不能检测到信号，此时移动终端可能离开上述信号覆盖区域，终端恢复原有的电压与电量第一对应关系，按照上述电压与电量第一对应关系重新确定电量不为关机电量后，触发开机。
另外，在发射装置信号覆盖范围之外的移动终端，由于无法接收到上述包含切换电压与电量对应关系消息和电压与电量对应关系的特定信息，电量不受到影响。
本发明实施例通过切换电池的电压与电量对应关系来达到改变电池当前电量的目的，从而控制移动终端关机，相比已有通过在特定区域干扰通讯信号的方式，本发明实施例将移动终端关机的方式更加安全，更好地保护信息的私密性。
