可选的,检测到电池的电量达到电量上限时,还可以对外广播充电完成通知,相应的处理过程可以如下:检测电池的电量;当电池的电量达到电池的电量上限时,通过第一近距离通讯天线,广播充电完成通知。
在实施中,在充电的过程中,第一终端可以周期性地检测电池的电量,当电池已充满即电池的电量达到电量上限时,可以通过第一近距离通讯天线通过电磁波对外广播充电完成通知。
可选的,针对调整电路与第一近距离通讯天线的连接线路上设置有连接开关的情况,第一终端接收到充电电磁波之后,还可以控制连接开关闭合,充电结束后,即充电电磁波消失时,可以控制连接开关断开,这样,第一近距离通讯天线用于近距离通讯功能时,不会减弱电磁波的强度,可以更好的将通讯消息输送到信号处理电路,可以使得第一近距离通讯天线、调整电路和电池组成电流回路。
可选的,针对第一终端对外广播充电完成通知的情况,第二终端相应的处理过程可以如下:通过第二近距离通讯天线,接收第一终端广播的充电完成通知;响应于充电完成通知,终止对外发射充电电磁波。

在实施中,第一终端对外广播对应发现消息的确认消息后,第二终端可以通过本地设置的第二近距离通讯天线接收第一终端广播的确认消息,将会触发第二终端弹出选择界面,选择界面中可以显示有NFC功能所能实现的功能的功能列表(即第二近距离通讯天线对应的功能列表),功能列表中可以包括通讯功能选项,也可以包括充电功能选项,等等,用户可以选取选择界面中的充电功能选项,将会触发第二终端开启相应的充电应用程序,第二终端将会接收到充电开启指令,进而,可以通过其中的第二近距离通讯天线,可以是NFC线圈,持续对外发射预设的用于充电的电磁波,开始对第一终端充电,充电过程可以按照图2中的步骤流程实现。在检测到第一终端的情况下再持续发射充电电磁波,可以有效节约第二终端中的电池的电能。
本发明实施例中,通过第一近距离通讯天线,接收第二终端发射的充电电磁波,通过调整电路,将接收到的充电电磁波形成的交流电流转换为直流电流,将转换得到的直流电流充入电池中。第二终端可以是用户随身携带的手机等移动终端,这样,当用户持有第一终端在外且第一终端需要充电时,用户可以用随身携带的第二终端为第一终端充电,即用户随时随地可以为第一终端充电,从而,可以增强为终端充电的灵活性。
基于相同的技术构思,本发明实施例还提供了一种第一终端,参照图6,第一终端包括机身、第一近距离通讯天线、调整电路和电池,第一近距离通讯天线、调整电路和电池放置于机身的内部,其中:第一近距离通讯天线与调整电路电性连接,第一近距离通讯天线用于接收充电电磁波;调整电路与电池电性连接,调整电路用于将接收到的充电电磁波形成的交流电流转换为直流电流,将直流电流充入电池中。
在实施中,第一终端可以是用户随身携带的终端,比如手环、智能项圈等,用户可以用手机、平板电脑等移动终端为随身携带的第一终端进行充电,其中,手机、平板电脑等移动终端可以发射充电电磁波(可以称为第二终端)。当终端需要充电时,用户可以将终端放在可以发射充电电磁波的手机、平板电脑等移动终端周围,比如终端放在可以发射充电电磁波的手机、平板电脑等移动终端10cm的范围内。
第二终端可以具有NFC(Near Field Communication,近场通信)功能,NFC功能可以通过NFC天线实现近距离通讯,也可以对其他的终端进行充电等,第二终端中可以安装有应用程序,用于控制第二终端中的NFC功能,近距离通讯功能和充电功能可以分别对应有各自的应用程序,可以分别称为通讯应用程序和充电应用程序。当用户需要对随身携带的第一终端充电时,可以通过设置选项开启第二终端中的NFC功能,之后可以通过充电应用程序开启充电功能。在第二终端中的NFC功能开启的状态下,用户可以通过操作触发第二终端启动本地安装的充电应用程序,此时第二终端将会接收到充电开启指令,进而,可以将本地电池输出的直流电流转化为具有预设电流值的交流电流,将其输送到近距离通讯天线,近距离通讯天线可以生成频率在预设频率范围且具有预设振幅的电磁波,持续对外发射用于充电的电磁波(可以将用于充电的电磁波称为充电电磁波)。

当电池已充满,即电池的电量达到电池的电量上限时,终端还可以通过第一近距离通讯天线对外广播充电完成通知,以便第二终端可以通过本地设置的近距离通讯天线接收到终端广播的充电完成通知,终止对外发射充电电磁波。这样,可以,可以防止第二终端中电池电量的浪费,同时也可以起到保护终端电池的作用。
