本申请涉及LED显示屏的供电控制领域，特别是涉及一种LED显示系统、供电控制方法和存储介质。
 背景技术
LED显示屏的功耗与当前画面亮度相关，通常是亮度越高，功耗越高。然而，在实际的使用过程中，灯珠往往不是一直处于功耗最高的状态。例如，全彩灯珠在较多的时候都不是显示为白色。因此，LED显示屏峰值功耗较高，而平均功耗较低，实际工作时峰值功耗维持时间较短。然而，在供电时，往往需要按照峰值功耗进行配电，目前LED显示屏均是通过外部电源进行供电，由于需要按照峰值功耗进行配电，导致供电的功率较高。

本申请各实施例的LED显示系统，通过额外配置供电电池，由供电电池在峰值功耗阶段提供功率较高的供电，外部接入的电源只需要参考平均功耗进行配电即可，能够降低LED显示屏对外部电源供电的功率需求。
下面结合附图详细描述本申请各实施例的LED显示系统。
请参阅图1，示例性的示出了本申请一实施例的LED显示系统10的结构示意图，LED显示系统10包括显示屏体110、控制系统120、配电箱130及供电电池140，控制系统120连接于显示屏体110，用于控制显示屏体110的画面显示；配电箱130电连接于控制系统120及显示屏体110，用于为控制系统120及显示屏体110供电；供电电池140连接于显示屏体110，并信号连接于控制系统120，当显示屏体110的功耗超过第一预设值时，控制系统120切断配电箱130对显示屏体110的供电，并控制供电电池140为显示屏体110供电。
通过配置供电电池140，在显示屏体110的功耗超过第一预设值时，显示屏体110的供电方由配电箱130更改为供电电池140，由供电电池140完成峰值阶段的供电。在显示屏体110的功耗较低时，由外部电源通过配电箱130以较低的功率进行供电，此时的供电功率只需要参照显示屏体110的平均功耗即可，例如，可以略微大于显示屏体110的平均功耗。在功耗超过第一预设值时，控制系统120可以给出一个控制信号，切断配电箱130对显示屏体110的供电，供电电池140开始为显示屏体110供电，由此，不会因为峰值功耗拉升外部电源的供电功率，能够降低显示屏体110对外部电源的功率需求。
可以理解，配电箱130配置有外部电源接口131，当通过电源线缆连接外部电源接口131与市电插座时，配电箱130即可为显示屏体110供电。在一个或多个实施例中，配电箱130电连接于供电电池140，并为供电电池140进行充电。具体的，当供电电池140处于空闲状态时，配电箱130可以为供电电池140充电，直至供电电池140电量满；以及，当供电电池140为显示屏体110进行供电时，配电箱130也可以为供电电池140进行充电，以避免供电时间过长导致供电电池140电量不足，影响显示屏体110的显示。
在具体的实施例中，为了避免配电箱130为供电电池140充电拉升外部电源的功率，配电箱130只在特定状态时为供电电池140充电。具体的，当显示屏体110的功耗小于第二预设值时，或者显示屏体110的功耗大于第一预设值时，配电箱130为供电电池140充电，其中，第二预设值小于第一预设值。显示屏体110的功耗小于第二预设值时，外部电源通过配电箱130对显示屏体110供电，由于显示屏体110本身的功耗相对平均功耗处于较低的位置，因此，外部电源的供电功率可以满足同时为显示屏体110供电及为供电电池140充电；当显示屏体110的功耗大于第二预设值时，由于外部电源的通过配电箱130为显示屏体110供电，若配电箱130同时为供电电池140充电，则可能会对显示屏体110的供电造成影响，因此，配电箱130不再为供电电池140充电；当显示屏体110的功耗大于第一预设值时，由供电电池140为显示屏体110供电，配电箱130不再为显示屏体110供电，因而，配电箱130可以为供电电池140进行充电，可以避免供电电池140在为显示屏体110供电过程中，电量耗尽，从而影响显示屏体110的显示。
请参阅图1和图2，在具体的实施例中，供电电池140可以设置于配电箱130内，或者设置于显示屏体110上。例如，当显示屏体110为拼接显示屏时，显示屏体110包括多个LED箱体，每个LED箱体上均可以配置有供电电池140。
上述LED显示系统10，通过配置供电电池140，在显示屏体110的功耗超过第一预设值时，显示屏体110的供电方由配电箱130更改为供电电池140，由供电电池140完成峰值阶段的供电。在显示屏体110的功耗较低时，由外部电源通过配电箱130以较低的功率进行供电，此时的供电功率只需要参照显示屏体110的平均功耗即可，例如，可以略微大于显示屏体110的平均功耗。在功耗超过第一预设值时，控制系统120可以给出一个控制信号，切断配电箱130对显示屏体110的供电，供电电池140开始为显示屏体110供电，由此，不会因为峰值功耗拉升外部电源的供电功率，能够降低显示屏体110对外部电源的功率需求。
请参阅图3，本申请还提供一种供电控制方法，应用于LED显示系统，具体可以包括步骤：
S110：确定显示屏体的一峰值功耗及一平均功耗，并确定第一预设值；
当显示屏体确定时，其峰值功耗就已确定，例如，当为单色（如绿色）灯珠，则控制全部灯珠以最大亮度显示单色（绿色），则，此时显示屏体的功耗即为峰值功耗；当灯珠为全彩灯珠时，控制全部灯珠以最大亮度显示白色，此时，显示屏体的功耗为峰值功耗。
在其中一些实施例中，可以根据峰值功耗和平均功耗确定第一预设值。当显示屏体显示不同的图像时，功耗值各不相同，因此，平均功耗值并不是一个特定的精确值，因此，平均功耗仅用于确定第一预设值。在具体的实施例中，可以使显示屏体正常播放一视频，记录显示屏体的功耗曲线，大部分时间内，显示屏体的功耗维持在一预设区间，可以由此确定第一预设值，例如，使第一预设值在平均功耗值与峰值功耗之间，取一略大于该预设区间的最大值的值作为第一预设值。当然，也可以使显示屏体播放多个不同视频，每个视频确定一个显示屏体的平均功耗，在进行适当的加权计算，得出最终的平均功耗值，再根据最终的平均功耗值，结合峰值功耗确定第一预设值。
当然，也可以通过其他的方式来确定第一预设值，例如只通过峰值功耗或平均功耗也可确定。
S120：获取显示屏体的功耗值；
为了达到降低给LED显示系统供电的外部电源的功率的目的，需要根据第一预设值来切换显示屏体的不同供电来源，避免在峰值功耗附近使用外部电源进行供电。由于供电是实时供电的，几乎很难根据时间曲线来进行供电来源的切换，因此，就需要根据显示屏体的功耗值确认是否切换供电来源。
在其中一些实施例中，显示屏体的功耗值为显示屏体的实时功耗值。此时，获取显示屏体的功耗值的步骤具体为：
获取显示屏体当前的的实时功耗值。
显示屏体在显示一帧图像时，控制系统可以实时检测显示屏体的功耗值，并根据当前时刻的实时功耗值作为是否切换供电来源的参考值。
在另一些实施例中，显示屏体的功耗值可以是下一帧图像的预测功耗值。此时，获取显示屏体的功耗值的步骤具体为：
预测显示屏体在显示下一帧图像时的功耗，并获取该预测值。
在具体的实施例中，控制系统可以基于历史时间段内的功耗值对下一帧图像的功耗值进行预测，并以此作为显示屏体的功耗值。由于视频是由多帧连续的图像快速切换形成，因此，相邻的两帧图像的同一像素点，在亮度、色彩上体现为一定的继承性，差异不大，体现在功耗曲线上，不会出现悬崖式的上升或下跌，一般都是逐渐过渡，因此，可以根据当前帧或当前帧的相近的一个时间段内的功耗值对显示屏体在显示下一帧图像时的功耗进行预测，能够得到一个和实际功耗相近的预测值。
或者，控制系统可以根据下一帧图像中各像素点的亮度信息计算得到。例如，控制系统在控制相应的图像显示时，相应的有配置文件，记载有对应像素点的亮度信息，每个像素点对应一个亮度值，每个亮度值均可以对应一个功耗值，综合所有像素点的功耗值，即可得到一个下一帧图像对应的功耗值，即为预测的下一帧图像的功耗值。
确定显示屏体的功耗值后，即可将显示屏体的功耗值与第一预设值进行比对，从而确定对应的供电策略。
S130：判断显示屏体的功耗值是否大于第一预设值，若是，切断配电箱与显示屏体之间的电路，使供电电池与显示屏体导通，以利用供电电池对显示屏体进行供电。
显示屏体的功耗值确认后，将显示屏体的功耗值与第一预设值比对，若高于第一预设值，则判断显示屏体即将进入功耗峰值阶段，此时切换为供电电池供电，在此后的一个时间间隔内，显示屏体均处于功耗峰值阶段，直至功耗降低至第一预设值以下，再切换为配电箱与显示屏体连接，通过外部电源进行供电。可以理解，若功耗值小于第一预设值，则继续维持第一配电箱对显示屏体供电。
请参阅图4，在一个或多个实施例中，步骤S130后，还可以包括步骤：
S140：当供电电池对显示屏体供电时，控制配电箱为供电电池充电。
当供电电池为显示屏体进行供电时，配电箱也可以为供电电池进行充电，以避免供电时间过长导致供电电池电量不足，影响显示屏体的显示。
请参阅图5，在一个或多个实施例中，还可以包括步骤：
S150：当通过配电箱为显示屏体供电时，若显示屏体的功耗值小于第二预设值，在配电箱为显示屏体供电的同时，控制配电箱为充电电池供电。
外部电源的供电功率恒定，显示屏体的功耗值则在不断的变化，外部电源通过配电箱对供电电池进行充电时，对功率形成分流，因此，为了避免对显示屏体的供电造成影响，可以定义一第二预设值，当小于第二预设值时，外部电源的供电功率可以满足同时为供电电池充电以及为显示屏体进行充电，以保证每次在切换供电电池为显示屏体供电时，供电电池具有足够的电量。
请参阅图6，在一个或多个实施例中，步骤S130具体可以包括：
S131：判断显示屏体的功耗值是否大于第一预设值；
S133：若是，获取就近的预设时间间隔内的功耗值，确认功耗值的变化趋势；
S135：若趋势上升，则控制供电电池为显示屏体供电；
S137：若趋势平稳，则获取该时间间隔内的多个大于第一预设值的功耗值，判断多个大于第一预设值的功耗值随时间的分布情况，若离散分布，则维持配电箱对显示屏体供电，否则，控制供电电池为显示屏体供电。
显示屏体的功耗可能在第一预设值附近的区域波动，此时，如果在功耗值刚大于第一预设值时即切换供电电池供电，在下一刻可能功耗值就小于第一预设值，可能导致在配电箱、供电电池之间来回切换。为了避免频繁切换，可以获取当前视频帧就近的时间间隔内的一组功耗值，根据该组功耗值可以得到就近时间间隔内的功耗值变化趋势，如果趋势上升，则在接下来一段时间内，功耗值也很大可能继续上升，因此，直接切换供电电池为显示屏体供电；如果趋势平稳，则将该时间间隔内的大于第一预设值的功耗值提取出来，并判断大于第一预设值的功耗值随时间的分布情况，如果离散分布，则说明显示屏体只在很短的一段时间内功耗大于第一预设值，且功耗值马上就降低到小于第一预设值以下，此时，为了避免频繁切换供电，维持配电箱对显示屏体的供电。
可以理解，在使用配电箱为显示屏体供电时，外部电源的供电功率可以满足显示屏体的功耗值稍微大于第一预设值时的供电，一方面，可以满足上述避免频繁切换的策略，另一方面，也可以在切换供电电池时提供足额的供电功率，避免供电不足。
上述供电控制方法，上述供电控制方法，通过在显示屏体的功耗超过第一预设值时，由配电箱为显示屏体供电更改为由供电电池为显示屏体供电，由供电电池完成峰值阶段的供电。在显示屏体的功耗较低时，由外部电源通过配电箱以较低的功率进行供电，此时的供电功率只需要参照显示屏体的平均功耗即可，在功耗超过第一预设值时，控制系统可以给出一个控制信号，切断配电箱对显示屏体的供电，供电电池开始为显示屏体供电，由此，不会因为峰值功耗拉升外部电源的供电功率，能够降低显示屏体对外部电源的功率需求。
