本申请涉及电子设备的无线充电，尤其涉及一种检测无线充电接收设备置于无线充电发射机的方法及装置。
目前，就无线充电领域而言，在无线充电接收设备(如手机、智能手表等)置于无线充电发射机(如无线充电底座)充电的过程中，如果无线充电接收设备满足一定条件，例如充电完成、过热或过流等等，无线充电接收设备则会向无线充电发射机发送停止充电的命令，在这种情况下，无线充电发射机虽然停止对无线充电接收设备充电，但却会周期性向无线充电接收设备发射一个检测信号，用于检测无线充电接收设备是否还置于其上。
对于上述情况来说，虽然现有技术实现了由无线充电发射机单向检测无线充电接收设备是否置于其上，但是却无法实现反过来的情形，即无法实现由无线充电接收设备来检测其是否置于无线充电发射机，更一步地说，现有技术还无法实现无线充电接收设备和无线充电发射机进行存在性的双向检测。

响应于停止充电命令的发送，判断是否检测到无线充电接收设备上
所产生的预定中断事件；
如果检测到该预定中断事件，则检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。

检测装置，用于响应于检测到预定中断事件，检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。
与现有技术相比，本申请的实施例具有以下优点：
本申请实施例通过检测无线充电接收设备自身是否发生预定中断时间，从而准确地检测出无线充电接收设备自身是否置于无线充电发射机，进而在现有技术的基础上实现了无线充电接收设备和无线充电发射机进行存在性的双向检测。
进一步地，本申请的实施例通过在无线充电接收设备上，将接收到的来自无线充电发射机发送的、用于检测其上是否存在无线充电接收设备的信号与预定中断事件关联，通过判断是否发生该关联的预定中断事件，从而有效地检测出无线充电接收设备自身是否置于无线充电发射机。

还应当提到的是，在一些替换实现方式中，所提到的功能/动作可以按照不同于附图中标示的顺序发生。举例来说，取决于所涉及的功能/动作，相继示出的两幅图实际上可以基本上同时执行或者有时可以按照相反的顺序来执行。
下面结合附图对本申请作进一步详细描述。
为了更好地突出本申请实施例的优点，先对无线充电发射机对置于其上的无线充电接收设备进行充电的过程进行描述。
其中本申请的实施例适用于包括但不限于由无线充电联盟(WPC)推出的Qi无线充电标准下的无线充电。
其中所述无线充电接收设备包括但不限于手机、智能手表以及其他可通过无线充电技术实现充电的电子设备。
其中所述无线充电发射机包括但不限于通过电磁感应耦合给电子设备传输电能的充电设备，如无线充电底座。
其中无线充电接收设备置于无线充电发射机可以指：无线充电接收设备位于无线充电发射机上，或位于其他可被无线充电发射机充电的位置，例如接近于无线充电发射机的位置。
图1示例性地示出了现有技术中无线充电发射机(简称“发射端”)和无线充电接收设备(简称“接收端”)的装置简图。
如图1所示，接收端包括接收端线圈、整流电路、接收端芯片、接收端电池和处理器，发射端包括发射端线圈、功率转换电路、发射端芯片和充电指示灯。对于接收端而言，接收端线圈基于电磁感应从发射端线圈获取感应电流的信号，从而该信号经过整流电路到达接收端芯片，进而接收端芯片在处理器的控制下向接收端电池进行充电；对于发射端而言，发射端芯片输出的功率通过功率转换电路的处理，到达发射端线圈，进而形成发射端线圈上的交变电流信号，该交变电流信号基于电磁感应，使接收
端线圈产生感应电流。另外，发射端还可以包括充电指示灯，以指示发射端是否处于给接收端充电的状态。
根据Qi无线充电标准，当接收端满足一定的条件，例如充电完成、过流、过热等等，接收端可以向发射端发送要求发射端停止输出功率(即充电)的命令。对于这种情况，可将其称为“功率停止输出”(EPT，EndPower Transfer)模式。
在EPT模式下，发射端将停止向接收端输出功率，但是仍会周期性地向接收端发送周期很短的脉冲信号，该脉冲用于检测接收端是否还被置于发射端上。对于发射端发射该脉冲的动作，在此可称为ping。
对于发射端的该ping动作，如果接收端被置于发射端上，发射端所发射的脉冲将会触发接收端内的相关芯片工作，以使接收端响应于该脉冲向发射端告知当前所在的状态，基于该状态，发射端可判断出接收端被置于发射端上。
虽然图1所示的装置实现了由无线充电发射机单向检测无线充电接收设备是否置于其上，但是却无法实现反过来的情形，即由无线充电接收设备来检测其是否置于无线充电发射机，更一步地说，现有技术还无法实现无线充电接收设备和无线充电发射机进行存在性的双向检测。
在一些场景中，实现由无线充电接收设备来检测其是否置于无线充电发射机是非常必要的。
以下述的场景为例：
为了在无线充电接收设备上实现尽可能高的充电效率，且为了防止充电过热的问题，实现尽可能低的充电温度，对无线充电接收设备进行间歇性地、高输出功率地充电，即以尽量高的输出功率对接收端进行快速充电，一旦充电的过程中该接收端的温度上升到某一值即由接收端向发射端发出命令暂停输出功率，如此便于使接收端的温度在暂停输入功率的情况下快速下降，而当下降到一定值，又可通过接收端向发射端发送命令的方式让发射端恢复高功率地充电。在发射端暂停向接收端输出效率的过程中，接收端的界面上往往会显示接收端已停止充电的指示，这种指示往往给用户的充电体验造成很不好的影响。因而，为了避免给用户造成时
而充电时而停止的不好体验，有必要在接收端的界面上做一些改进，使接收端暂停充电的过程中也能显示为充电，这种界面上的改进可以给用户带来连续充电的较好体验。
但是，上述界面改进所针对的暂停充电指的是接收端仍位于发射端上、发射端随时可能恢复对接收端输出电功率的情形，而一旦接收端没有位于发射端上，则需要接收端仍能正确地显示其已停止充电。
而基于现有的技术，由于只能由无线充电发射机单向检测无线充电接收设备是否置于其上，但是却无法实现反过来的情形，因而当接收端没有位于发射端的情况下，接收端的界面却错误地显示其还在充电。
为了解决诸如上述场景的问题，本申请通过对接收端进行改进，从而使接收端在充电的过程中可以基于自身的检测来准确地判断其是否还位于发射端。
请参考图2，图2示出了根据本申请一个实施例的无线充电接收设备的示意性框图。
根据图2，所述无线充电接收设备包括：
接收装置201，包括用于响应来自无线充电发射机发送的用于检测其上是否存在无线充电接收设备的信号，产生电平信号的信号管脚。
处理器202，包括与所述信号管脚相连接并基于所述电平信号产生预定中断事件的中断管脚。
检测装置203，用于响应于检测到预定中断事件，检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。
其中接收装置201可以指无线充电接收设备中用于接收发射端发射的无线电信号并基于处理器202的控制命令进行相应响应的芯片。
其中，上述组件201～203可以是独立的组件，也可以是组合在一起的组件，例如上述检测装置203可以包含于处理器202中。
以检测装置203包含于处理器202中为例，请参考图3，图3示出了根据本申请实施例的无线充电发射机(简称“发射端”)和无线充电接收设备(简称“接收端”)的装置简图。
如上文所述，在EPT模式下，发射端将停止向接收端输出功率，但是仍会周期性地向接收端发送周期很短的脉冲信号(为便于描述，在此将该脉冲信号简称为“ping脉冲”)，该脉冲用于检测接收端是否还被置于发射端上。对于这种情况，如果接收端置于发射端上，接收装置201(如图3中的接收端芯片)的一些管脚上通常会产生一些电平信号，暂且将这些管脚称为“信号管脚”。为了及时有效地检测出该电平信号，本申请将信号管脚连接到处理器202的中断管脚，该中断管脚在接收到该电平信号的情况下会在处理器202上引发预定的中断事件的发生。从而，一旦检测装置203检测到该中断事件，即可使无线充电接收设备检测出其还位于无线充电发射机上。
也即，接收端每接收到一个上文所述的ping脉冲，都会在处理器上产生一个中断事件，从而接收端只需要基于对该中断事件的检测即可有效地检测出接收端是否还位于发射端上。
进一步地，为了避免信号管脚和中断管脚的直接连接导致接收装置201上的过大电流等而影响接收装置201的正常工作，所述无线充电接收设备还包括：
-电阻，该电阻一端与所述中断管脚串联，另一端与信号管脚串联，用于限定所述接收装置的电信号大小。
如图3所示，其中的电阻被串联在接收装置201的信号管脚和处理器202的中断管脚之间，用于防止该串联电路上产生过大电流，该电阻优选地为高阻抗电阻。
优选地，为了更及时地检测出接收端是否还位于发射端上，还可以在接收端上安装一个计时器(timer)，该计时器可与发射端的处理器相连接，当接收端的处理器通过诸如控制接收端芯片向发射端发送要求发射端停止输出功率(即充电)的命令，则处理器控制该计时器进行设定时间的计时或倒计时，从而所述检测装置203响应于设定的时间内没有检测到中断事件的情况下，检测出所述无线充电接收设备没有置于无线充电发射机，反之，则检测出所述无线充电接收设备置于无线充电发射机上。
对于检测装置203检测的过程而言，该计时器会相应地进行倒计
时，如果接收端在倒计时的时间内检测到中断事件，该计时器将重置并在检测装置203需要检测的时候重新倒计时。
优选地，为了提高检测的准确性，将所述计时器设置的倒计时的时间设置成大于或等于所述信号的周期，从而针对发射端进入到EPT模式下的每一个所述信号的周期，在等于或略大于该周期的时间内来检测中断事件。
根据本申请的一个实施例，还提供了一种与上述任一个实施例所述的无线充电接收设备耦合的无线充电发射机。
根据本申请的一个实施例，请参考图4，图4为本申请一个实施例的用于检测无线充电接收设备置于无线充电发射机的装置的示意性框图。
其中本申请的装置位于无线充电接收设备上，适用于包括但不限于由无线充电联盟(WPC)推出的Qi无线充电标准下的无线充电。
其中所述无线充电接收设备包括但不限于手机、智能手表以及其他可通过无线充电技术实现充电的电子设备。
其中所述无线充电发射机包括但不限于通过电磁感应耦合给电子设备传输电能的充电设备。
其中无线充电接收设备置于无线充电发射机可以指：无线充电接收设备位于无线充电发射机上，或位于其他可被无线充电发射机充电的位置，例如接近于无线充电发射机的位置。
根据图4，所述装置包括：
状态判断单元301，用于在无线充电发射机给无线充电接收设备充电的过程中，检测无线充电接收设备的状态是否满足特定条件。
命令发送单元302，用于响应于无线充电接收设备的状态满足特定条件，向无线充电发射机发送停止充电的命令。
中断事件判断单元303，用于响应于停止充电命令的发送，判断是否检测到无线充电接收设备上基于该信号所产生的预定中断事件。
检测单元304，用于响应于检测到无线充电接收设备上基于该信号所产生的预定中断事件，检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。
下文将对上述单元进行详述。
对于状态判断单元301而言，所述无线充电接收设备的状态满足特定条件可以包括以下中的至少一项：
-无线充电接收设备处于充电完成的状态；
-无线充电接收设备的温度上升到预定高值；
-无线充电接收设备的电流超过预定电流值。
对于命令发送单元302而言，当无线充电接收设备处于诸如充电完成、过热、过流等状态，则会向发射端发送一个使其停止向接收端输出功率的命令，即停止充电的命令，该过程即为上文的EPT模式。
如上文所述，当进入EPT模式，发射端通常会停止向接收端输出功率，但是仍会周期性地向接收端发送周期很短的脉冲信号(为便于描述，在此将该脉冲信号简称为“ping脉冲”)，该脉冲用于检测接收端是否还被置于发射端上。对于这种情况，如果接收端置于发射端上，接收端通常会基于所接收到的该ping脉冲而产生相应的电信号变化，如在其内的一些芯片的引脚上产生电平信号，而本申请可以通过检测该电平信号来判断接收端是否置于发射端。
在本实施例中，可以通过在发射端中诸如处理器上设置与该电平信号对应的事件，常见如处理器上的中断事件，一旦检测到该电平信号，则触发处理器上中断事件的发生，从而将对电平信号的检测转化为中断事件的产生，从而更准确更明显地判断出接收端是否置于发射端上。
因而，对于所述中断事件判断单元303而言，可选地，其用于：
-判断是否检测到无线充电接收设备上、基于接收到的无线充电发射机发送的用于检测其上是否存在无线充电接收设备的信号、所产生的预定中断事件。
具体而言，当接收端接收到发射端发送的用于检测其上是否存在无线充电接收设备的信号，该接收端上会产生相应的电信号变化，通过将该电信号与接收端上的预定中断事件关联，从而如果发生该相应的电信号变化，则在接收端发生该预定中断事件，从而通过检测单元304对预定中断事件的检测，准确有效地判断出接收端置于发射端，反之，则接收端没
有置于发射端。
优选地，为了更及时更准确地判断出接收端是否置于发射端，所述中断事件判断单元303用于：
-判断是否在预定时间内检测到无线充电接收设备上所产生的预定中断事件；
所述检测单元304，用于：
-如果在预定时间内检测到该预定中断事件，则检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。
可选地，所述预定时间大于或等于所述信号的周期。
也即，针对发射端进入到EPT模式下的每一个所述信号的周期，在等于或略大于该周期的时间内由接收端来检测中断事件，而不是在任何情况下的任何时间对中断事件进行检测，既可以避免检测功率的浪费，又可以因检测周期等于或大于发射端的发射的该信号的周期而及时检测出无线充电接收设备是否置于无线充电发射机上。
与现有技术相比，本实施例可以针对上文所述的EPT模式(接收端向发射端发送要求发射端停止输出功率的命令)下的接收端，有效地检测出其是否位于发射端上，从而在接收端的UI界面上进行正确地充断电提示。
图5为本申请一个实施例的检测无线充电接收设备置于无线充电发射机的方法流程图。
其中，本申请可以适用于包括但不限于由无线充电联盟(WPC)推出的Qi无线充电标准下的无线充电。

步骤S102，响应于停止充电命令的发送，判断是否检测到无线充电接收设备上所产生的预定中断事件。
步骤S103，如果检测到该预定中断事件，则检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。
具体地，对于步骤S101，所述无线充电接收设备的状态满足特定条件可以包括但不限于以下中的至少一项：
无线充电接收设备处于充电完成的状态；
无线充电接收设备的温度上升到预定高值；
无线充电接收设备的电流超过预定电流值。
进一步地，当无线充电接收设备处于诸如充电完成、过热、过流等状态，则会向发射端发送一个使其停止向接收端输出功率的命令，即停止充电的命令，该过程即为上文的EPT模式。
如上文所述，当进入EPT模式，发射端通常会停止向接收端输出功率，但是仍会周期性地向接收端发送周期很短的脉冲信号(为便于描述，在此将该脉冲信号简称为“ping脉冲”)，该脉冲用于检测接收端是否还被置于发射端上。对于这种情况，如果接收端置于发射端上，接收端通常会基于所接收到的该ping脉冲而产生相应的电信号变化，如在其内的一些芯片的引脚上产生电平信号，而本申请可以通过检测该电平信号来判断接收端是否置于发射端。
在本实施例中，可以通过在发射端中诸如处理器上设置与该电平信号对应的事件，常见如处理器上的中断事件，一旦检测到该电平信号，则
触发处理器上中断事件的发生，从而将对电平信号的检测转化为中断事件的产生，从而基于步骤S102，响应于停止充电命令的发送，判断是否检测到无线充电接收设备上所产生的预定中断事件，更具体地判断是否检测到无线充电接收设备上、基于接收到的无线充电发射机发送的用于检测其上是否存在无线充电接收设备的信号、所产生的预定中断事件。
进一步地基于步骤S103，如果检测到该预定中断事件，则检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机更准确，从而更明显地判断出接收端是否置于发射端上。
可选地，上述判断是否检测到无线充电接收设备上所产生的预定中断事件包括：
-判断是否在预定时间内检测到无线充电接收设备上所产生的预定中断事件；
所述如果检测到该预定中断事件，则检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机的步骤包括：
-如果在预定时间内检测到该预定中断事件，则检测出所述无线充电接收设备置于无线充电发射机，否则，则检测出所述无线充电接收设备没有置于无线充电发射机。
其中，所述预定时间大于或等于所述信号的周期。
也即，针对发射端进入到EPT模式下的每一个所述信号的周期，在等于或略大于该周期的时间内由接收端来检测中断事件，而不是在任何情况下的任何时间对中断事件进行检测，既可以避免检测功率的浪费，又可以因检测周期等于或大于发射端的发射的该信号的周期而及时检测出无线充电接收设备是否置于无线充电发射机上。
