附图中所示的方框图仅仅是功能实体，不一定必须与物理上独立的实体相对应。即，可以采用软件形式来实现这些功能实体，或在一个或多个软件硬化的模块中实现这些功能实体或功能实体的一部分，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
电力载波控制灯串的方法用于控制通过电力线串联的灯串。如图1所示，本实施例电力载波控制灯串的方法，包括以下步骤：步骤S1，通过接收到的随机采样数据或者指定数据得出要控制的灯源地址、灯珠地址以及显示模式，组成控制字符串；步骤S2，将头部字符串、控制字符串、结束字符串组成控制指令；步骤S3，将控制指令加载到电力线中并下发至灯源中执行。如图2所示，一条灯串中设有若干灯源以及一个载波调制器，载波调制器主要控制该串灯串的灯源及灯珠。灯源包括主控单元以及四个不同颜色灯珠(譬如红、绿、蓝、白)，主控单元用于读取控制指令并控制灯珠工作。在其他实施例中，灯源中可以设置的灯珠数量可进行调整。如图3所示，当存在多于1条灯串时，所有灯串直接物理并联或通过分处理器连接到主处理器，由主处理器分别调控对应的灯串。
在步骤S1中，随机采样数据通过在设定频率下对数据流进行逐次采样得到。设定频率是指每隔若干秒钟便进行采样，譬如每隔两秒钟采集数据流中的若干字节数据。设定频率可以出厂确定，也可以由产品使用者自由修改。被采样的数据流可以是有线传输的数据流，譬如数据端口传输时，直接读取数据端口的数据流，不管数据流是否有加密。被采样的数据流也可以是无线传输的数据流，譬如可以在无线网卡上直接读取数据流。随机采样数据具有较高的随机性，因此后续所得出的控制字符串也会有极高的随机性，这样控制灯串的点亮效果不会轻易重复。
本实施例中，每次对数据流进行采样均采集4个字节的十六进制数据。将其中两个字节用于确定灯源的地址，一般可以用本身连续的前两个字节作为灯源地址。譬如，两个连续的字节为006A，换算成十进制就是106，也即是就是第106个灯源。对于单个灯串中灯源数量并不多(小于4096个)的情况下，四位的十六进制数可以截取其中三位十六进制数 用于确定灯源的地址，譬如随机采样数据其中两字节为C10F，截取低三位10F，也即是十进制271，作为灯源地址，当然也可以截取高三位C10作为灯源地址。在其他实施例中，对于单个灯串中灯源数量并不多(小于4096个)的情况下，还可以让四位的十六进制数对灯串的灯源数量求余运算，得出余数必然不大于灯串的灯源数量，便可以作为灯源的地址，而如果余数是零，则灯源地址为000。
剩余的两个字节中，其中一个字节用于确定灯源中的灯珠，最后一个字节用于确定灯源的工作模式。如果灯源中的灯珠数量不多，比如本实施例的灯源中有四个灯珠，可将确定灯珠的字节截取其中一位来确定灯源中的灯珠组合。例如，灯源四个灯珠分别是白、红、绿、篮，四个灯珠所能形成的组合的对应映射表如下表1：
表1
数值 组合
00 全部灯珠
01 红
02 绿
03 蓝
04 白
05 红绿
06 红蓝
07 红白
08 绿蓝
09 绿白
10 蓝白
11 红绿蓝
12 红绿白
13 红蓝白
14 绿蓝白
15 红蓝白
若字节为1F，截取低位F，若组合的总数小于F，则F与总数求余运算，得到的余数在映射表里面找出对应的灯珠。当然，在其他实施例中，用于确定灯珠的字节也可以不进行截取，而直接与灯珠组合数量求余，得到余数后在映射表中查找出对应的灯珠组合。另外，还要注意的是，若灯源的灯珠只有一个，则组合只有一种，无论字节是什么数值，最终结果都只会是00。
剩余的两个字节中的最后一个字节用于确定灯源的工作模式。本实施例工作模式的映射表，列出如表2。
表2
Figure PCTCN2021072306-appb-000001
若字节为7C，截取低位C，C超过5，则C与总数5求余得到2，也即是十六进制的02，也即对应快闪工作模式。当然，在其他实施例中，用于确定工作模式也可以不进行截取，而直接与工作模式数量求余运算，得出余数在映射表中查询便可以确定工作模式。因而，若随机采样数据四字节为C10F1F7C，经过上面的操作，得到控制字符串是“10F0502”， 其代表的内容是第271个灯源的红绿灯珠快闪。
步骤S1中，若接收到的是指定数据，则需要从指定数据中确定出控制字符串。指定数据一般是通过使用者在人机界面上输入，譬如使用输入的是：显示的指定内容为五角星，红色，常亮，那么指定数据就包含五角星、红色及常亮。这些指定数据包含了指定内容，则需要在已存储的特定图案映射表里面寻找出指定内容所对应的灯源地址合集。特定图案映射表可以包含，譬如所有英文字母、日常语言字体、常见图案等等，满足使用者的常规使用需求。指定数据中的“红色”则在表1中查询到对应的是“01”，常亮在表2中查询到对应的是“01”，因而得到的多个控制字符串就是“灯源地址X+01+01”，灯源地址X需遍历所得到的灯源地址合集。当出现多个控制字符串时，应该在控制字符串之间***分隔字符串(譬如EEFF)，执行时灯源便知道后续的控制字符串也是需要执行的，避免出现控制中断。
在其他实施例中，步骤S1中接收到的指定数据为设定的默认指令字符串，则将指定数据直接作为控制字符串。表3是一个默认指令字符串与控制功能的映射表例子。

步骤S2中需要将头部字符串、控制字符串、结束字符串组成完整的控制指令。头部字符串起到了识别作用，当灯源主控单元读取到头部字符串，则表明控制指令开始，主控单元需要开始按照控制字符串进行控制。若灯源主控单元未读取到头部字符串，则不开始工作，这样便可以避免误触发。结束字符串表面该条控制指令接收，当灯源主控单元读取到结束字符串，则保持之前控制指令包含的工作模式，等待下一个头部字符串的到来。
作为例子，头部字符串是“AF68CE07”，结束字符串是“5E5F”，控制字符串是“010F0502”，则控制指令则是“AF68CE07010F05025E5F”，所实现的控制功能是让第271个灯源的红绿灯珠快闪。若还需要第3088个灯源的蓝灯珠常亮，则还应加入控制字符串“0C100301”、分隔字符串“EEFF”，控制指令变成“AF68CE07010F0502EEFF0C1003015E5F”。
作为另一个例子，控制字符串是“006A+02+01”及“0FA8+10+02”，灯珠字节分别是02、10，工作模式字节分别是01、02，分隔字符串是“EEFF”，则得到的控制指令是“AF68CE07006A0201EEFF0FA810025E5F”，所实现的控制功能是让第 106个灯源里面的绿色灯珠常亮，然后第4008个灯源里面的蓝色白色灯珠快闪。
步骤S3是将得到的控制指令通过载波调制器加载到电力线中并下发至灯源中执行。在面对控制多条灯串的情况时，可以有多种方式来得到控制指令。如果由同一个主处理器同时控制多条灯串，可以为不同的灯串分配对应的不同的头部字符串，这样主处理器发出的控制指令所有灯串都可以收到，但只有正确对应的灯串会执行该控制指令。另外，还可以让主处理器和分处理器协同工作，先由主处理器将随机采样数据或指定数据分配到灯串上的分处理器，让分处理器组合成控制对应该条灯串的控制指令，再进行下发执行。
在本发明的示例性实施例中提供了一种电子广告牌。这种电子广告牌是由至少1条灯串组成的灯串矩阵。在实施时，电子广告牌尺寸越大，所需灯串便越多。电子广告牌的灯串矩阵采用前述的控制灯串的方法。在电子广告牌中设有字库模块，其中字库模块是一个数据映射库，可以包含对应英文字母、日常语言字体、常见图案等等的灯源地址合集，也即是只要知道要查询的内容，便可以知道对应的灯源地址合集。譬如，在使用电子广告牌时，想要显示闪烁的“S”字样，那么就在字库模块中搜寻对应字母S的灯源地址合集，然后通过前述的步骤S1-S3便让合集中的所有灯源都点亮并闪烁，电子广告牌便可以显示出一个闪烁的“S”字样。同理，若要显示其他文字或者符号甚至图片也是通过如此方式在电子广告牌上显示。字库模块的内容可以出厂时设定好，使用者后续使用时可以往字库模块加入更多新的映射，使其可以显示更多样化的内容。
