但是，在上述开关信号线连接到上述通信信号线的情况下，如果用户误操作无人机的上述开关按键，会中断电池与飞行控制器之间的通信，造成数 据丢失。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，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，都属于本发明保护的范围。
图2为本发明一实施例提供的电池控制电路的结构示意图，如图2所示，本实施例的电池控制电路可以包括：控制器210、通信信号线220、操作开关230以及开关电路240。
控制器210，用于控制电池的工作状态。
通信信号线220，用于电连接所述控制器210与所述电池，使得所述控 制器210与所述电池通信连接。
操作开关230，与所述通信信号线220电连接，用于通过所述通信信号线220发送开关信号给所述电池，以控制所述电池给所述控制器210供电；以及
开关电路240，电连接于所述操作开关230与所述通信信号线220之间，用于控制所述操作开关230与所述通信信号线220之间的通信导通或断开。
其中，当所述操作开关230控制所述电池给所述控制器210开始供电之后，所述开关电路240控制所述操作开关230与所述通信信号线220之间的通信断开，以阻止所述操作开关230发送开关信号至所述通信信号线220。
本实施例中，控制器210可以通过通信信号线220与电池通信连接，控制器210通过通信信号线220控制电池的工作状态。其中，电池的电参数可以通过通信信号线220传输给控制器210，电池的电参数例如可以包括以下至少一项：电压、电流等，控制器210可以根据电池的电参数控制电池的工作状态，例如控制器210可以在电池的电参数满足一定条件时，则控制器210控制电池向被供电设备供电，驱使被供电设备工作。
本实施例在操作开关230与通信信号线220之间设置有开关电路240，开关电路240可以控制操作开关230与通信信号线220之间的通信导通或者断开。在开关电路240控制操作开关230与通信信号线220之间的通信导通时，操作开关230可以通过通信信号线220向电池发送开关信号，电池在接收到开关信号后，电池根据该开关信号向控制器210供电，控制器210即可工作，然后控制器210可以控制电池的工作状态。在开关电路240控制操作开关230与通信信号线220之间的通信断开时，通信信号线220不会接收到操作开关230发出的信号，因此，即使用户误操作操作开关230，操作开关230均不会影响到通信信号线220，从而不会影响到电池与控制器210之间的通信，保证了电池与控制器210之间数据的正常传输。
其中，操作开关230的状态例如可以为闭合状态或者断开状态，若操作开关230处于闭合状态，则操作开关230可以发出开关信号，若操作开关230处于断开状态，则操作开关230不会发出开关信号。
在一些实施例中，操作开关230例如可以是旋钮开关或者按键开关等，本实施例对此不做限定，其中，图3以操作开关230为按键开关为例进行图 示，其中图3中示出按键开关接地，但本实施例并不限于此，在操作开关230为按键开关时，用户按下按键开关，此时按键开关闭合，在开关电路240控制按键开关与通信信号线220之间的通信导通的情况下，按键开关会向电池发送低电平信号，该低电平信号可以认为是开关信号，电池在接收到低电平信号后开始给控制器210供电。在开关电路240控制按键开关与通信信号线220之间的通信断开的情况下，按键开关发送的电平信号不会干扰到通信信号线220。
图4本发明另一实施例提供电池控制电路的结构示意图，如图4所示，本实施例的电池控制电路在图2或图3所示的电池控制电路的基础上，所述开关电路240电连接控制器210，控制器210，用于在所述电池给所述控制器供电后，控制开关电路断开，以控制所述操作开关与所述通信信号线之间的通信断开。
本实施例中，在电池给控制器210供电前，开关电路240是开启的，也可以认为开关电路240常态开启，在开关电路240开启时，开关电路240控制操作开关230与通信信号线220之间的通信导通。在电池给控制器210供电后，控制器210控制开关电路240断开，在开关电路240断开时，开关电路240控制操作开关230与通信信号线220之间的通信断开。
在另一些实施例中，开关电路240的断开不受控于控制器210，具体参见图2或图3所示的电池控制电路。开关电路240，用于在电池向控制器210供电后自动断开。本实施例中，在电池给控制器210供电前，开关电路240是开启的，也可以认为开关电路240常态开启，在开关电路240开启时，开关电路240控制操作开关230与通信信号线220之间的通信导通。在电池给控制器210供电后，开关电路240自动断开，在开关电路240断开时，开关电路240控制操作开关230与通信信号线220之间的通信断开。
在上述各实施例的基础上，开关电路240可以包括电子开关，其中，电子开关包括如下至少一种：绝缘栅双极型晶体管，金属氧化物半导体场效应晶体管(Metal-Oxide-Semiconductor Field-Effect Transistor，MOS管)，固态继电器，晶闸管。
图5为本发明另一实施例提供的电池控制电路的结构示意图，如图5所示，本实施例以开关电路240包括MOS管为例进行说明。本实施例的电池控 制电路在图2或图3所示的电池控制电路的基础上，上述的开关电路240包括第一MOS管241，该第一MOS管241可以控制操作开关230与通信信号线220之间的通信导通或者断开。其中，第一MOS管241，用于在第一MOS管241导通时，控制操作开关230与通信信号线220之间的通信导通，以及在第一MOS管241断开时，控制操作开关230与通信信号线220之间的通信断开。
在一些实施例中，第一MOS管241，用于在所述第一MOS管241的源极与所述第一MOS管241的栅极的电平差满足预设条件时导通，以控制所述操作开关230与所述通信信号线220之间的通信导通；以及用于在所述第一MOS管241的源极与所述第一MOS管241的栅极的电平差不满足预设条件时断开，以控制所述操作开关230与所述通信信号线220之间的通信断开。
在一些实施例中，上述的开关电路240还包括第一电容242和第一电阻243，所述第一电容242的两端分别电连接所述第一MOS管241的源极和栅极，所述第一MOS管241的栅极电连接于所述第一电容242与所述第一电阻243之间，所述第一MOS管241的源极还电连接所述通信信号线220与所述第一电容242之间，所述第一MOS管241的漏极电连接所述操作开关230。本实施例开关电路240通过设置的第一电容242和第一电阻243来控制第一MOS管的导通或断开。
在一些实施例中，所述第一电容242，用于在所述第一MOS管241断开时通过所述第一电阻243充电，并在充电的过程中控制所述栅极的电平下降，直至所述源极与所述栅极的电平差满足预设条件；以及用于在所述第一MOS管241导通时通过所述第一电阻243放电，并在放电的过程中控制所述第一MOS管241的栅极的电平上升，直至所述源极与所述栅极的电平差不满足预设条件。
本实施例中，在电池插到电池控制电路上时，电池给通信信号线220输出的是高电平(例如3.3V或者5V等)，因此第一MOS管241的源极为高电平，而且第一MOS管241的源极依次连接第一电容242和第一电阻243，本实施例中的第一电阻243可以接地，所以第一电容242可以通过第一电阻243充电。又由于第一MOS管241的栅极连接在第一电容242与第一电阻243之间，因此，在第一电容242通过第一电阻243充电的过程中，第一MOS 管241的栅极的电平下降，当第一MOS管241的栅极的电平下降至第一MOS管的源极与第一MOS管241的栅极的电平差满足预设条件时，第一MOS管241导通，从而操作开关230与通信信号线220之间的通信导通。
其中，图5以操作开关230为按键开关为例示出，且按键开关的一端还接地，因此当用户按压操作开关230时，操作开关230处于开启状态，由于操作开关230接地，因此操作开关230的电平拉低为低电平(例如0V)，相应地，与操作开关230电连接的第一MOS管241的漏极的电平也拉低为低电平。另外由于第一MOS管241导通，所以第一MOS管241的漏极的电平影响到第一MOS管的源极的电平，使得第一MOS管241的源极的电平拉低为低电平，由于第一MOS管241的源极通过通信信号线220与电池电连接，因此，在第一MOS管241的源极的电平为低电平时，通信信号线220的电平也为低电平，在电池通过通信信号线220检测到低电平后，电池开始给控制器210供电。
在第一MOS管的源极的电平拉低为低电平后，第一电容242放电，使得第一MOS管241的栅极的电平升高，然后第一MOS管241的源极与第一MOS管241的栅极之间的电平差会发生变化，当第一MOS管241的源极与第一MOS管的栅极之间的电平差不满足预设条件时，第一MOS管241断开。在第一MOS管241断开时，操作开关230与通信信号线220之间的通信也断开，因此，即使用户误操作操作开关230，也不会干扰到通信信号线220。
在一些实施例中，本实施例的电池控制电路还包括：供电信号线250。所述供电信号线250用于电连接所述控制器210与所述电池，使得所述电池通过所述供电信号线250向所述控制器供电。本实施例中的控制器210还通过供电信号线250与电池电连接，电池通过供电信号线向控制器210供电，其中，电池通过供电信号线向控制器210供电时输出的电平为高电平(例如3.3V或者5V等)。
本实施例的开关电路240还包括第一二极管244。其中，该第一二极管244的负极电连接第一MOS管241的栅极，第一二极管244的正极电连接所述供电信号线250。本实施例中，所述电池在开始向控制器210供电后，还通过所述供电信号线250向第一MOS管241的栅极供电以控制所述第一MOS管241的栅极的电平上升。本实施例中，电池通过供电信号线250向控制器 210供电，第一二极管244的正极也电连接到该供电信号线250。在电池开始向控制器210供电后，电池通过供电信号线输出的电平为高电平，由于第一二极管244的正极电连接到该供电信号线，在电池通过供电信号线输出高电平时，第一二极管244导通，然后电池向第一MOS管241的栅极供电，第一MOS管241的栅极的电平上升，直至第一MOS管241的栅极的电平与电池的输出电平相同，此时第一MOS管241的栅极的电平为高电平。因此，电池向控制器开始供电后，第一MOS管241的栅极为高电平，这会导致第一MOS管241的源极与第一MOS241的栅极的电平差不满足预设条件，从而锁死第一MOS管241，即第一MOS管241处于断开状态。因此，本实施例将第一MOS管241的栅极电连接第一二极管244，并且第一二极管244电连接电池，从而保证电池向控制器210供电后，第一MOS管241不会导通。
第一二极管244可以防止电池插入到电池控制电路上时，第一MOS管241的源极的高电平通过第一电容242和与电池连接的供电信号线250而被拉低为低电平，避免了电池一插入到电池控制电路上未经操作开关的控制就向控制器供电。
图6为本发明另一实施例提供的电池控制电路的结构示意图，如图6所示，本实施例的电池控制电路在图5所示的电池控制电路的基础上，开关电路240还包括第二MOS管245，所述第二MOS管245电连接于所述第一二极管244与所述供电信号线250之间；所述第二MOS管245，用于控制所述第一二极管244与所述供电信号线250之间的电连接导通，使得所述电池向所述第一MOS管241的栅极供电。
其中，在第二MOS管245导通时，第一二极管244与供电信号线250之间的电连接导通，然后电池可以通过供电信号线250向第一MOS管241的栅极供电。
在一些实施例中，所述第二MOS管245还电连接控制器210。所述控制器210，用于控制所述第二MOS管245导通以控制所述第一二极管244与所述供电信号线250之间的电连接导通。第二MOS管245受控于控制器210，控制器210控制第二MOS管导通还是断开，第二MOS管245可以认为常态断开，在电池向控制器210供电后，控制器控制第二MOS管245导通，在第二MOS管245导通时，第一二极管244与供电信号线250之间的电连接也导 通，然后电池可以通过供电信号线250向第一MOS管241的栅极供电。
在一些实施例中，所述第二MOS管245的源极与所述供电信号线250电连接，所述第二MOS管245的栅极与所述控制器210电连接，所述第二MOS管245的漏极与所述第一二极管244的正极电连接。
所述控制器210，用于控制所述第二MOS管245的栅极的电平下降，直至所述第二MOS管245的源极与所述第二MOS管245的栅极的电平差满足预设条件时导通。
本实施例中，电池向控制器210供电后，由第二MOS管245的源极与供电信号线电连接，因此第二MOS管245的源极为高电平，而且，控制器210控制第二MOS管245的栅极的电平下降，例如：控制器210与第二MOS管245的栅极电连接，控制器210可以向第二MOS管245的栅极发出低电平信号，使得第二MOS管245的栅极的电平为低电平，从而使得第二MOS管245导通，第二MOS管245导通后，电池可以向第一MOS管的栅极供电。
图7为本发明另一实施例提供的电池控制电路的结构示意图，如图7所示，本实施例的电池控制电路在上述各实施例的基础上，还包括信号输出电路260。所述信号输出电路260电连接在所述操作开关230与所述控制器210之间。
所述信号输出电路260，用于当所述操作开关230控制所述电池给所述控制器开始供电之后，根据所述操作开关230的状态不同，向所述控制器输出不同的电平。
所述控制器210，用于根据所述信号输出电路260输出的电平，输出相应的控制信号。
本实施例中，在操作开关230控制电池向控制器210开始供电后，开关电路240也控制操作开关230与通信信号线220之间的通信断开，用户操作操作开关230，不会干扰到通信信号线。另外，本实施例还在操作开关230与控制器210之间设置有信号输出电路260，用户可以操作操作开关230，使得操作开关230处于不同的状态，由于信号输出电路260与操作开关230电连接，操作开关230的状态不同，信号输出电路260会向控制器210输出不同的电平，然后控制器210，根据信号输出电路260输出的电平，输出相应的控制信号。因此，在操作开关230与通信信号线220之间的通信断开后， 用户通过操作操作开关230还可以实现其它控制功能。
在一些实施例中，所述控制信号包括以下至少一种：用于控制所述电池复位重启的控制信号，用于控制被供电设备执行相应动作的控制信号。
图8为本发明另一实施例提供的电池控制电路的结构示意图，如图8所示，本实施例在上述实施例的基础上，所述信号输出电路260包括：第二电容261和第二电阻262。
所述第二电阻262电连接在所述第二电容261和所述电池之间，且所述控制器210电连接在所述第二电容261。
所述第二电容261，用于在所述电池给所述控制器210开始供电之后，在所述操作开关230处于闭合状态时，通过所述第二电阻262充电并向所述控制器210输出高电平，在所述操作开关230处于断开状态时放电并向所述控制器210输出低电平。
本实施例中，第二电阻262电连接在第二电容261与电池之间，例如：第二电阻262电连接到电池给控制器210供电的供电信号线上，在电池给控制器210开始供电后，供电信号线输出的电平为高电平，如果用户操作操作开关230处于断开状态，电池通过供电信号线和第二电阻262向第二电容261充电，第二电容261充电时，由于控制器210电连接在第二电容261与第二电阻262之间，控制器210检测到低电平。如果用户操作操作开关230处于闭合状态，第二电容261放电，控制器210检测到低电平。然后控制器210可以根据检测到的以至少一种：低电平的时长、高电平的时长、低电平的次数、高电平的次数来输出对应的控制信号。
在一些实施例中，所述信号输出电路260还包括：第二二极管263；其中，所述第二二极管263的正极电连接在所述第二电阻262与所述第二电容261之间，所述第二二极管263的负极电连接在所述开关电路240与所述操作开关230之间。本实施例的第二二极管263可以防止在按键开关向电池发送开关信号之前第一MOS管241的漏极由高电平拉低为低电平，避免了电池一插入到电池控制电路上未经操作开关的控制就向控制器供电。
需要说明的是，图8中所示的两个控制器210其实为同一控制器210。
图9为本发明另一实施例提供的电池控制电路的结构示意图，如图9所示，本实施例的电池控制电路在上述任一实施例的基础上，所述电池的数量 和所述通信信号线220的数量均为N，所述N为大于或等于2的整数；所述N个电池与所述N个通信信号线一一对应电连接；
其中，所述N个所述通信信号线220并联连接到所述开关电路240。
由于N个通信信号线220并联连接到开关电路240，在开关电路240可以控制操作开关230与N个通信信号线220之间的通信均导通，操作开关230可以通过N个通信信号线220分别向N个电池发送开关信号，以控制N个电池均向控制器210供电。因此，只要N个通信信号线220中任一通信信号线220电连接到电池，本实施例的电池控制电路可以控制该电池进行供电。而现有技术中，如图1所示，开关按键是电连接到一个通信信号线，如果被供电设备可以由多个电池供电时，只有当电池插入到被供电设备并与开关按键连接的通信信号线连接时，开关按键才能控制电池向控制器供电，若电池插入到被供电设备但未与开关按键连接的通信信号线连接时，开关按键无法控制电池向控制器供电，因此，现有技术的开关按键只能控制一个电池给控制器供电。而本发明实施例规避了现有技术中的缺陷，只要有电池插入到被供电设备电连接通信信号线时，本实施例就可以控制电池向控制器供电，因此，本实施例可以控制多个电池向控制器供电。
在一些实施例中，本实施例的电池控制电路还包括：N个第三二极管270，所述N个第三二极管270的正极并联连接到所述开关电路240，并且所述N个第三二极管270的负极与所述N个所述通信信号线220一一对应电连接。本实施例中的第三二极管270可以避免各个电池之间数据的相互干扰。
图10为本发明一实施例提供的电源控制系统的结构示意图，如图10所示，本实施例的电源控制系统1000可以包括：电池控制电路1001和至少一个电池1002。所述电池控制电路1001，用于控制所述至少一个电池1002进行供电。其中，所述电池控制电路1001可以采用上述任一实施例的结构，其实现原理和技术效果类似，此处不再赘述。
图11为本发明一实施例提供的可移动平台的结构示意图，如图11所示，本实施例的可移动平台可以包括：机体1101、动力系统1102以及电源控制系统1103。其中，所述电源控制系统1103可以采用上述实施例的结 构，其实现原理和技术效果类似，此处不再赘述。
其中，电源控制系统1103中的电池控制电路1103a以及至少一个电池1103b安装于所述机体1101。至少一个电池1103b可以外挂在机体1101外，也可以安装在机体1101内。
所述至少一个电池1103b，用于向所述动力系统1102提供电能；
所述动力系统1102，用于给所述可移动平台提供移动动力。
在一些实施例中，所述可移动平台为无人机或者地面摇控机器人。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
