具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
使用可拆卸式的电池装置进行供电的电子设备越来越多，例如无人机、手持云台等。
发明人发现，通常，电池装置上设置有输出按键，在电池装置和被供电装置连接后，需要人工操作电池装置上设置的输出按键，电池装置获知被供电装置在位，从而电池装置才会给被供电装置进行供电，否则，电池装置无法获知被供电装置在位，从而不会给被供电装置供电，被供电装置无法正常工作。
然而，上述在电池装置上设置输出按键的方式，存在电池装置的设计不够简洁的问题。为了满足电子设备的便携化和轻巧化的需求，需要思考如何进行简洁化设计，对结构设计要求高。其中的一个方法就是，应用控制电路替代按键。当电子设备接入电池时，电池可检测到电子设备在位，电池将自动输出电压给电子设备供电。无需按下按键，控制电池输出。但是，如果使用常规的在位检测，需要额外的连接接口。如果增加额外的连接接口，一方面连接接口不便于加工生产，另一方面需要额外的空间、对结构设计造成困难，同时从产品外观上看也不够美观、简洁。此外，与原电池装置相配套使用的电池管家、充电器等装置都不能兼容新的电池装置使用，这些配套产品也将被迫根据连接端子的变化而进行升级迭代。因此不利于电池和配套产品的归一化管理，增加研发工作量。
基于上述至少一个问题，本申请实施例提出复用连接接口的方式，对于其中一个连接接口，既保留原有的接口功能，又为其新增在位检测功能。
本申请实施例可以应用于如图1所示的应用场景中，如图1所示，该应用场景可以包括第一装置11，以及能够与第一装置11可拆卸连接的第二装置12。其中，在第二装置12与第一装置11连接在一起时，表示第一装置11在位。在第二装置12未与第一装置11连接在一起时，表示第一装置11不在位。
如图1所示，第一装置11包括控制电路11A和连接接口11B，控制电路11A与连接接口11B电连接。其中，连接接口11B用于第一装置11与第二装置12进行电连接。当第一装置11与第二装置12连接在一起时，控制电路11A用于根据连接接口11B的电平信号，确定第二装置12在位。
可以理解的是，第二装置12中可以包括与连接接口11B匹配的接口，以便于第二装置12与连接接口11B进行电连接。所述第一装置11中用于所述第一装置与所述第二装置进行电连接的接口，除了包括所述连接接口11B，还可以包括所述连接接口11B之外的其他接口。
需要说明的是，本申请实施例可以应用于第一装置11需要获知第二装置12在位的任意类型场景，基于第二装置12的在位，第一装置11可以由第一状态切换至第二状态。
一个实施例中，第一装置可以包括电池装置，第二装置可以包括被供电装置，第一状态可以为供电通路断开状态，第二状态可以为供电通路导通状态。
一个实施例中，第一装置可以包括电池装置，第二装置可以包括云台或无人机机身，实现电池装置使用控制电路11检测云台(或无人机机身)的在位，以在云台(或无人机机身)在位情况下，导通供电通路以便向云台(或无人机机身)供电。
一个实施例中，在第二装置包括云台，第一装置包括电池装置情况下，第一装置可以安装于云台手柄的壳体内，从而使得手持云台场景下安装于云台手柄内的电池装置能够采用控制电路11A实现云台的在位检测。手持云台的结构可以如图2A-图2H所示，参考图2A-图2H，手持云台包括云台21和云台手柄22，云台手柄22的壳体内安装有电池装置(未示出)。需要说明的是，图2A-图2H所示的手持云台的结构仅为举例。
可选的，连接接口11B可以穿设所述壳体而暴露在所述壳体的外部，从而能够便于电池装置的连接接口11B与云台进行电连接。安装有电池装置的云台手柄22的结构可以如图3A-图3F所示，参考图3A-图3F，云台手柄22的壳体22A内安装有电池装置，电池装置的连接接口11B穿设壳体22A而暴露在壳体22A的外部。需要说明的是，图3A-图3H所示的云台手柄22的结构仅为举例。
可选的，所述云台手柄和所述云台可拆卸连接，从而能够通过云台手柄和云台的可拆卸连接，使得电池装置和云台连接或者不连接。
传统技术中，电池装置上设置有按键，如果电池装置获取到针对该按键的触发操作，则可以确定被供电装置在位，如果电池装置未获取到针对该按键的触发操作，则认为被供电装置不在位，电池装置上需要设置该按键，导致电池装置的设计不够简洁。
本申请实施例中，通过第一装置包括控制电路11A和连接接口11B，控制电路11A根据连接接口11B的电平信号，确定第二装置在位，实现了控制电路11A通过复用连接接口11B的方式实现对第二装置12的在位检测，即连接接口11B既用于第一装置11与第二装置12进行电连接，又用于控制电路11A针对第二装置12进行在位检测，使得第一装置上无需设置专用于第一装置针对第二装置进行在位检测的按键，从而使得第一装置的设计更加简洁。
