Description

一种充电设备自环检测方法及装置 技术领域
本发明涉及电路技术领域，尤其涉及一种充电设备自环检测方法及装置。
背景技术
移动电源因其可以方便的为平板电脑、手机等设备充电而得到了广泛的应用。如图1所示，移动电源1包括大容量电池10、电源管理电路11、对内充电接口12和对外充电接口13等，其中，对内充电接口12用于外部充电器为移动电源1充电，对外充电接口13用于移动电源1给外部设备(例如，平板电脑、手机等)充电。为了方便用户使用，移动电源最好可以对内充电和对外充电同时进行。
如图1所示，有些用户可能会将对内充电接口12和对外充电接口13直接连接，导致移动电源1内部形成一个电流环(下文中将该电流环称为自环)，这样会白白的消耗掉移动电源1中的电能，同时，若连接时间过长，移动电源1过度发热可能还会损坏其内部电路。目前，当移动电源1对内充电和对外充电同时进行时，不对移动电源1内是否存在自环进行检测。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
实施例一
本发明实施例提供一种充电设备自环检测方法，所述充电设备包括对内充电接口和对外充电接口，所述对内充电接口包括Di正信号线和Di负信号线，所述对外充电接口包括Do正信号线和Do负信号线；所述对内充电接口处于对内充电状态，所述对外充电接口处于对外充电状态；如图2所示，所述方法包括：
201、将所述Do正信号线和所述Do负信号线从连接状态切换为断开状态。
需要说明的是，本发明实施例中的充电设备可以给外部设备(例如，手机、平板电脑等)充电，外部充电器也可以给该充电设备充电。具体的，充电设备可以为移动电源，也可以为其他具有上述功能的设备。本发明实施例的执行主体可以为充电设备，也可以为其他可以实现上述方法的检测设备，本发明实施例不对其进行限制。本发明实施例中以执行主体为检测设备为例对本发明实施例提供的技术方案进行示例性说明。
其中，如图3所示，充电设备3包括对内充电接口31和对外充电接口32。其中，对内充电接口31和对外充电接口32均包括D正(也可以表示为“D+”)信号线和D负(也可以表示为“D-”)信号线，本发明实施例为了方便描述和区分，将对内充电接口31的D正信号线表示为Di正信号线(图3中表示为Di+)，对内充电接口31的D负信号线表示为Di负信号线(图3中表示为Di-)；对外充电接口32的D正信号线表示为Do正信号线(图3中表示为Do+)，对外充电接口32的D负信号线表示为Do负信号线(图3中表示为Do-)。
当对内充电接口31和对外充电接口32直接连接、且对内充电接口31和对外充电接口32均处在工作状态时，充电设备3内会存在自环。
另外，参见图3，对内充电接口31和对外充电接口32均包括一个电源线(图3中均表示为V)和一个地线(图3中均表示为G)，一般情况下，对内充电接口31和对外充电接口32连接同一条地线。充电设备3中还可以包括大容量电池、电源管理电路等(图3中未示出)。
步骤201在具体实现时，可以在Do正信号线和Do负信号线之间设置开关，检测设备可以通过开关控制Do正信号线和Do负信号线之间连接或断开。
需要说明的是，本发明实施例中，在将Do正信号线和Do负信号线从连接状态切换为断开状态之后，充电设备的对外充电接口还是处于对外充电状态，即对外充电接口的电源线处于供电状态。
202、检测所述Di正信号线和所述Di负信号线是否从连接状态切换为断开状态，若是，确定所述充电设备存在自环。
需要说明的是，外部充电器在为充电设备充电时，连接外部充电器和充电设备的对内充电接口的连接线的两端均会有与外部充电器和对内充电接口对应的电源线、地线、D正信号线和D负信号线。将外部充电器的D正信号线和D负信号线分别记为Dn+和Dn-。那么当外部充电器为一个标准充电器且外部充电器在为充电设备充电时，Dn+和Dn-是连接 在一起的，Di+和Di-也会连接在一起形成经过Dn+、Dn-、Di-和Di+最后回到Dn+的一个回路。当外部充电器为一个非标准充电器且外部充电器在为充电设备充电时，Dn+和Dn-不是连接在一起的，Di+和Di-也不会连接在一起。因此，充电设备可以通过检测Di-和Di+是否连接判断外部充电器是否为一个标准充电器。
同理，当充电设备为外部设备充电时，外部设备也可以通过上述方法检测充电设备是否为一个标准充电器。
需要说明的是，当外部充电器为充电设备充电时，若充电设备识别外部充电器为标准充电器，则不会限制流入自身的电流大小；若充电设备识别外部充电器为非标准充电器，则会限制流入自身的电流大小。在一次充电过程中，充电设备仅仅在充电刚开始的时候识别一次外部充电器是否为标准充电器。当充电设备为外部设备充电时，同理。
本发明实施例中，只要充电设备处于对外充电状态，Do正信号线和Do负信号线就是连接的，那么，若充电设备上存在自环，Di正信号线和Di负信号线是连接的；当Do正信号线和Do负信号线从连接状态切换为断开状态时，Di正信号线和Di负信号线也会从连接状态切换为断开状态。因此，可以通过该特性检测充电设备是否存在自环。
下面通过一个表格(表1)更加清楚的示出当对内充电接口处于不同的状态时，在检测设备执行步骤201前后，Di正信号线和Di负信号线之间的状态(该状态为连接或断开)、供电设备是否存在自环，以及Di正信号线和Di负信号线是否从连接状态切换为断开状态(表中简写为“是否切换”)的对应关系。表中将执行步骤201前Di正信号线和Di负信号线之间的状态称为A状态，执行步骤201后Di正信号线和Di负信号线之间的状态称为B状态。
表1
Figure PCTCN2015073953-appb-000001
由表1可以看出，只要对外充电接口处于对外充电状态，检测设备就可以通过检测Di正信号线和Di负信号线是否有连接状态与断开状态之间的切换，确定充电设备是否存在自环。
由表1也可知，只有对外充电接口处于对外充电状态、对内充电接口处于对内充电状态且Di正信号线和Di负信号线连接时，充电设备中才可能存在自环。本发明实施例中，在判断Di正信号线和Di负信号线之间连接后开始对充电设备进行检测，提高了检测设备的检测效率。
需要说明的是，当检测设备未检测到充电设备存在自环时，充电设备的Do正信号线和Do负信号线可以恢复成短接状态。
可选的，在步骤202之后，所述方法还可以包括：
控制所述对外充电接口进入停止对外充电状态；或，
控制所述对内充电接口进入停止对内充电状态；或，
控制流入所述对内充电接口的电流值，使所述电流值小于所述充电设备存在自环时的最大电流值。
需要说明的是，当检测设备控制对外充电接口进入停止对外充电状态或控制对内充电接口进入停止对内充电状态时，会消除充电设备内 存在的自环。
当检测设备控制流入对内充电接口的电流值时，充电设备中仍然存在自环，但是，由于该电流值小于充电设备存在自环时的最大电流值，因此，可以减少由于充电设备内存在自环带来的电能损耗。并且，该电流值越小越好，因为该电流值越小，充电设备内存在自环带来的电能损耗就越小。需要说明的是，由于充电设备开始识别到的为自己充电的外部充电器(充电设备存在自环时即是充电设备)为标准充电器，因此，不会去限制流入自身的电流大小。当充电设备存在自环时，检测设备控制流入对内充电接口的电流值。
具体的，当检测设备检测到充电设备内存在自环时，可以向充电设备中的电源管理电路输出一控制消息，电源管理电路根据该控制消息控制其内部电路，进而控制对内充电接口或对外充电接口的状态。
可选的，在步骤202之后，所述方法还可以包括：输出提示消息；其中，所述提示消息用于提示用户所述充电设备存在自环。
示例性的，检测设备可以通过指示灯的亮灭或者在显示屏上显示数字/文字的方式提示用户，当检测设备具有通信功能时，还可以通过向用户的手机等设备发送消息提示用户，本发明实施例对此不进行限制。另外，用户得知充电设备存在自环时，可以手动消除自环，具体可以通过拔掉连接充电设备的对内充电接口和/或对外充电接口上的连接线的方式消除充电设备的自环。
可选的，在所述输出提示消息之后，所述方法还包括：
确定所述充电设备的自环是否消除；
若否，控制所述对外充电接口进入停止对外充电状态；或，
若否，控制所述对内充电接口进入停止对内充电状态；或，
若否，控制流入所述对内充电接口的电流值，使所述电流值小于所述充电设备存在自环时的最大电流值。
可选的，所述确定所述充电设备的自环是否消除，包括：检测所述对外充电接口上的连接线是否移除，和/或，检测所述对内充电接口上的连接线是否移除；若移除，确定所述充电设备的自环消除。
示例性的，检测设备可以检测对内充电接口的电源线的电压是否为零，若为零，确定对内充电接口上的连接线移除。
需要说明的是，当用户移除充电设备的对外充电接口或者对内充电接口上的连接线时，检测设备可以检测到该情况，若在检测设备输出提示消息后的一定时间段内，检测设备检测到该情况，则可以确定充电设备的自环消除；若在检测设备输出提示消息后的一定时间段内，检测设备未检测到该情况，则可以确定充电设备的自环未消除。
需要说明的是，本发明实施例中，对外充电接口处于停止对外充电状态时，对外充电接口上的连接线未移除；对内充电接口处于停止对内充电状态时，对内充电接口上的连接线也未移除。
另外，对外充电接口重新处于对外充电状态的触发条件可以为：用户手动设置，或，对外充电接口上的连接线重新连接，或，对内充电接口上的连接线重新连接。
本发明实施例提供的充电设备自环检测方法，在对外充电接口处于对外充电状态、对内充电接口处于对内充电状态且Di正信号线和Di负信号线连接时，检测充电设备是否存在自环。当充电设备存在自环时，对外充电接口的Do正信号线和对外充电接口的Do负信号线从连接状态切换为断开状态，对内充电接口的Di正信号线和对内充电接口的Di负信号线也会从连接状态切换为断开状态，因此可以通过该特性检测充电设备存在自环。
实施例二
该实施例是对上述实施例提供的充电设备自环检测方法的一个具体的实施例，本实施例中的相关解释可以参见上述实施例；如图 4所示，该充电设备自环检测方法包括：
401、充电设备的对外充电接口处于对外充电状态。
此时，对外充电接口的Do正信号线和对外充电接口的Do负信号线连接。具体的，Do正信号线和Do负信号线之间可以设置有开关，检测设备可以通过开关控制Do正信号线和Do负信号线之间连接或断开。
402、检测充电设备的对内充电接口是否处于对内充电状态。
若是，执行步骤403；若否，执行步骤407。
具体的，当检测设备检测到对内充电接口的电源线上有电压时，认为对内充电接口处于对内充电状态。
403、检测对内充电接口的Di正信号线和对内充电接口的Di负信号线是否连接。
若是，执行步骤404；若否，执行步骤407。
需要说明的是，由于对外充电接口的Do正信号线和对外充电接口的Do负信号线连接，当充电设备存在自环时，对内充电接口的Di正信号线和对内充电接口的Di负信号线是连接的。
需要说明的是，该实施例中，检测设备对充电设备内是否存在自环进行检测的触发条件为：对外充电接口处于对外充电状态、对内充电接口处于对内充电状态且Di正信号线和Di负信号线连接。
404、将对外充电接口的Do正信号线和对外充电接口的Do负信号线从连接状态切换为断开状态。
405、检测对内充电接口的Di正信号线和对内充电接口的Di负信号线是否切换为断开状态。
若是，确定充电设备存在自环，执行步骤406；若否，执行步骤407。
406、控制对外充电接口进入停止对外充电状态。
407、结束。
本发明实施例提供的充电设备自环检测方法，在对外充电接口处于对外充电状态、对内充电接口处于对内充电状态且Di正信号线和Di负信号线连接时，检测充电设备是否存在自环。当充电设备存在自环时，对外充电接口的Do正信号线和对外充电接口的Do负信号线从连接状态切换为断开状态，对内充电接口的Di正信号线和对内充电接口的Di负信号线也会从连接状态切换为断开状态，因此可以通过该特性检测充电设备存在自环。
实施例三
本发明实施例提供了一种充电设备自环检测方法，所述充电设备包括对内充电接口和对外充电接口；如图5所示，所述方法包括：
501、将所述对外充电接口从对外充电状态切换为停止对外充电状态。
本发明实施例中的相关解释可以参见上述实施例。
具体的，检测设备可以在充电设备的对外充电接口开始对外充电且对内充电接口开始对内充电时，开始对充电设备内是否存在自环进行检测。
502、检测所述对内充电接口是否从对内充电状态切换为停止对内充电状态；若是，确定在所述对外充电接口处于对外充电状态时，所述充电设备存在自环。
具体的，当充电设备上存在自环时，充电设备的对内充电接口和对外充电接口是连接在一起的，那么，当对外充电接口从对外充电状态切换为停止对外充电状态时，对内充电接口自然会从对内充电状态切换为停止对内充电状态。因此，可以通过该特性判断充电设备是否存在自环。
具体的，在步骤501之后，检测设备已经将充电设备内的自环消除，但是，并未将连接充电设备的对内充电接口和对外充电接口的连接线拔掉，那么在充电设备下次开启时还会存在自环。
可选的，在步骤502之后，该方法还可以包括：输出提示消息；其中，所述提示消息用于提示用户当所述对外充电接口再次处于对外充电状态时，所述充电设备内存在自环。
具体的，用户看到提示消息时，可以拔掉连接充电设备的对内充电接口和/或对外充电接口上的连接线，防止充电设备在下次开启时还存在自环。
另外，对外充电接口重新处于对外充电状态的触发条件可以为：用户手动设置，或，对外充电接口上的连接线重新连接，或，对内充电接口上的连接线重新连接。
