Description

一种LED显示装置的地址编码写入方法及系统
本发明属于数据编码控制领域，尤其涉及一种LED显示装置的地址编码写入方法及系统。
随着LED显示装置在各种场合和领域的广泛应用，市场终端客户对LED显示装置的可靠性要求越来越高，而可靠性的其中一个重要保证就在于LED显示装置的架构模式，由于串联的架构模式存在诸多弊端，所以现有的LED显示装置多采用并联的架构模式形成一个完整LED显示或装饰模组，即所有的LED显示装置以并联的形式共享同一信号总线。为了达到预期的显示效果，每个LED显示装置必须具备自己的地址编码以对信号总线中相应的数据流进行截取，从而根据所截取的数据流进行显示。因此，并联的多个LED显示装置需要在生产时或在工程安装调试时进行地址编码，然后才能投入使用。现有技术所提供的地址编码写入方式是通过写码装置对逐一对每个LED显示装置进行地址编码写入操作，虽然能够实现写码操作，但是耗时较长，写码效率低，不利于对LED显示装置实现大规模的写码操作，进而影响生产效率和工装测试效率。
本发明的目的在于提供一种LED显示装置的地址编码写入方法，旨在解决现有技术所存在的写码效率低，不利于对LED显示装置实现大规模的写码操作而影响生产效率和工装测试效率的问题。

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例通过在一个LED显示模组中的所有相互并联的LED显示装置均串联有相同数量的LED显示装置时，根据预设地址编码和预设串联个数值以地址编码递增方式，从首个LED显示装置开始依次对与所述首个LED显示装置相并联的一个或多个LED显示装置以及与所述一个或多个LED显示装置中的每一个LED显示装置相串联的LED显示装置进行地址编码写入操作，实现了对LED显示装置的一次性写码操作，不必再逐一对LED显示装置进行写码，进而提升了写码效率。
图1示出了本发明实施例提供的LED显示装置的地址编码写入方法的实现流程，为了便于说明，仅示出了与本发明相关的部分，详述如下：
在步骤S1中，根据用户的设定生成预设地址编码和预设串联个数值。
其中，预设地址编码是指LED显示模组中第一个进行地址编码写入操作的LED显示装置，且该LED显示装置是所有相互并联的LED显示装置中的其中一个，所以，也可以把预设地址编码称为起始地址编码；预设串联个数值是指相互并联的LED显示装置中的每一个LED显示装置所串联的LED显示装置的个数。
在步骤S2中，当一个LED显示模组中的所有相互并联的LED显示装置均串联有相同数量的LED显示装置时，根据预设地址编码和预设串联个数值对首个LED显示装置以及与首个LED显示装置相串联的LED显示装置进行地址编码写入操作，且依据预设地址编码和预设串联个数值以地址编码递增方式依次对与首个LED显示装置相并联的一个或多个LED显示装置以及与一个或多个LED显示装置中的每一个LED显示装置相串联的LED显示装置进行地址编码写入操作。
对于步骤S2，实际上就是以预设地址编码作为首个LED显示装置的地址编码，然后根据预设串联个数值对与其串联的LED显示装置以地址编码递增方式逐一进行写码操作，而后续的与首个LED显示装置相并联的第一个LED显示装置的地址编码也是在前一个LED显示装置（即与首个LED显示装置串联且处于同一供电支路的LED显示装置中的最后一个）的地址编码的基础上递增后所形成的，所以，LED显示模组中的其他的LED显示装置也是按照上述同样的方式进行地址编码写入操作。
在步骤S3中，当LED显示模组中的各个相互并联的LED显示装置所串联的LED显示装置的数量不完全相同或完全不同时，每一次只根据预设地址编码对相互并联的LED显示装置中的一个LED显示装置进行地址编码写入操作，并根据所述预设地址编码和所述预设串联个数值以地址编码递增方式依次对与所述一个LED显示装置相串联的LED显示装置进行地址编码写入操作，并跳转回步骤S1。
对于步骤S3，因为处于每一个供电支路的LED显示装置的数量不完全相同或完全不同，这样就无法如步骤S2那样可以只设定一次地址编码和串联个数值就能够完成对所有LED显示装置的自动写码，而只能每一次仅对相互并联的LED显示装置中的一个LED显示装置以及与该一个LED显示装置相串联的LED显示装置进行地址编码写入操作，也就是相当于手动写码，即每一次进行地址编码写入操作时，都需要由用户设定好地址编码和串联个数值，然后从每一个供电支路中的第一个LED显示装置（即相互并联的LED显示装置中的其中一个）开始根据串联个数值依次增加地址编码以实现对与该第一个LED显示装置串联的LED显示装置进行地址编码写入操作。虽然这样不如步骤S2的写码效率高，但相对于现有技术需要对每个LED显示装置进行写码操作而言，步骤S3还是能够一次性对处于同一供电支路且相互串联的所有LED显示装置进行地址编码写入操作，所以还是能够在一定程度上提高写码效率的。
在步骤S4中，当LED显示模组中的LED显示装置成功写入地址编码时，驱动LED显示装置中的LED以第一颜色进行发光提示。
当LED显示模组中的LED显示装置未成功写入地址编码时，则驱动LED显示装置中的LED以第二颜色进行发光提示或者控制LED显示装置中的LED不发光。
其中，第一颜色和第二颜色分别为不同颜色，如第一颜色为红色，第二颜色为绿色。
在本发明另一实施例中，如图2所示，在上述步骤S1之后还包括以下步骤：
步骤S5，对预设地址编码和预设串联个数值进行显示。
这样可以让用户更加直观地获知LED显示装置的地址编码信息和所串联的LED显示装置的个数。
以下结合具体实例对上述的LED显示装置的地址编码写入方法作进一步说明：
（1）对应上述步骤S2的情况，如图3所示，假设LED显示模组中包括50个LED显示装置，相互并联的LED显示装置为5个，剩余的45个LED显示装置分为5组分别与前述的5个LED显示装置串联，也就是每一供电支路上有10个LED显示装置，共5条供电支路，且对这50个LED显示装置以LED1-LED50进行编号，LED1、LED11、LED21、LED31及LED41相互并联于同一信号总线，LED1至LED10为第一供电支路，LED11至LED20为第二供电支路，LED21至LED30为第三供电支路，LED31至LED40为第四供电支路，LED41至LED50为第五供电支路。用户先设定了LED1的地址编码和每一供电支路上除LED1、LED11、LED21、LED31及LED41之外的相互串联的LED显示装置的串联个数值，然后从LED1开始逐个往后一直到LED50增加地址编码以进行写码操作，例如地址编码为二进制编码，LED1的地址编码为00000001，LED2的地址编码则为00000010，则根据串联个数值以地址编码递增的方式顺序对每一供电支路上的LED显示装置进行写码，一直到LED50的编码为00110010。因此，就能达到一次性对LED显示模组中的所有LED显示装置进行自动写码操作。
（2）对于上述步骤S3的情况，如图4所示，假设LED显示模组中包括50个LED显示装置，其中，LED1至LED8为第一供电支路，LED9至LED15为第二供电支路，LED16至LED25为第三供电支路，LED26至LED32为第四供电支路，LED33至LED50为第五供电支路，由于各个供电支路上的LED显示装置的数量不同，所以只能由用户在进行地址编码写入操作之前依次对LED1、LED9、LED16、LED26以及LED33的地址编码进行设定，并对每一供电支路上剩余的相互串联的LED显示装置的串联个数值进行设定。例如，对LED1的地址编码设定为00000001，且第一供电支路上的串联个数值为7，则第一次只对LED1至LED8进行地址编码写入操作，从00000001到00001000；然后再由用户设定LED9的地址编码为00001010，且第二供电支路的串联个数值为6，则第二次对LED9至LED15进行地址编码写入操作，从00001010到00010000，以此类推对第三供电支路、第四供电支路及第五供电支路分次进行地址编码写入操作。
图5示出了本发明另一实施例提供的LED显示装置的地址编码写入方法的实现流程，为了便于说明，仅示出了与本发明相关的部分，详述如下：
在本实施例中，步骤S101、步骤S102及步骤S103分别与图1所示的步骤S1、步骤S2及步骤S3相同，因此不再赘述。另外，本实施例所提供的地址编码写入方法还包括：
步骤S104，当LED显示模组中的LED显示装置成功写入地址编码时，驱动LED显示模组的外接显示介质对当前的地址编码进行显示。
在本发明另一实施例中，如图6所示，在上述步骤S101之后还包括以下步骤：
步骤S105，对预设地址编码和预设串联个数值进行显示。
图7示出了本发明实施例提供的LED显示装置的地址编码写入系统的模块结构，为了便于说明，仅示出了与本发明相关的部分，详述如下：
本发明实施例提供的LED显示装置的地址编码写入系统包括设定模块100和主控模块200。
设定模块100用于根据用户的设定生成预设地址编码和预设串联个数值。
主控模块200用于当一个LED显示模组中的所有相互并联的LED显示装置均串联有相同数量的LED显示装置时，根据所述预设地址编码和所述预设串联个数值对首个LED显示装置以及与首个LED显示装置相串联的LED显示装置进行地址编码写入操作，且依据所述预设地址编码和所述预设串联个数值以地址编码递增方式依次对与首个LED显示装置相并联的一个或多个LED显示装置以及与所述一个或多个LED显示装置中的每一个LED显示装置相串联的LED显示装置进行地址编码写入操作。
当所述LED显示模组中的各个相互并联的LED显示装置所串联的LED显示装置的数量不完全相同或完全不同时，主控模块200每一次只根据所述预设地址编码对相互并联的LED显示装置中的一个LED显示装置进行地址编码写入操作，并根据所述预设地址编码和所述预设串联个数值以地址编码递增方式依次对与所述一个LED显示装置相串联的LED显示装置进行地址编码写入操作，并跳转回设定模块100。
地址编码写入系统还包括：
发光提示驱动模块300，内置于LED显示装置中，用于当LED显示模组中的LED显示装置成功写入地址编码时，驱动LED显示装置中的LED以第一颜色进行发光提示。
另外，当LED显示模组中的LED显示装置未成功写入地址编码时，则发光提示驱动模块300会驱动LED显示装置中的LED以第二颜色进行发光提示或者控制LED显示装置中的LED不发光。
在实际应用中，上述的地址编码写入系统的具体实现方式可如下：
设定模块100可以是具有一个多位拨码开关和一个按键的编码电路，用户可分别对多位拨码开关和按键进行操作以设定预设地址编码和预设串联个数值。
主控模块200可以是具有一微处理器和输出信号转换电路的控制电路，当一个LED显示模组中的所有相互并联的LED显示装置均串联有相同数量的LED显示装置时，其根据设定模块100所设定的预设地址编码和预设串联个数值以地址编码递增方式从首个LED显示装置开始一直到最后一个LED显示装置进行一次性自动写码操作；当LED显示模组中的各个相互并联的LED显示装置所串联的LED显示装置的数量不完全相同或完全不同时，则需要由用户分次通过设定模块100设定地址编码和串联个数值后，主控模块200每一次只对相互并联的LED显示装置中的一个LED显示装置以及与之串联的LED显示装置进行写码操作。其中的输出信号转换电路主要是对微控制器所输出的写码信号转换成RS485信号、5V至12V的TTL信号并输出至LED显示装置以实现写码操作。
发光提示驱动模块300可以是用于驱动LED发光的驱动电路，当LED显示装置写码成功时，驱动LED显示装置中的LED以第一颜色（如绿色）进行发光提示，当LED显示装置写码失败时，驱动LED显示装置中的LED以第二颜色（如红色）进行发光提示或控制或者控制LED显示装置中的LED不发光。
需要说明的是，当用户将多位拨码开关中的所有开关均拨到默认状态或接地，则表示LED显示模组中相互并联的LED显示装置均不串联任何LED显示装置，所以不需要对串联个数值进行设定。
为了让用户能够更加直观地掌握地址编码和串联个数值的设定情况，在本发明另一实施例中，如图8所示，地址编码写入系统还包括：
显示模块400，用于对预设地址编码和预设串联个数值进行显示。
在实际应用中，上述包括显示模块400的地址编码写入系统的具体实现方式可如下：
设定模块100可以是具有多个按键的按键编码电路，用户可对多个按键进行操作以设定预设地址编码和预设串联个数值，相对于前述的多位拨码开关而言，本实现方式采用按键设定需要用户多次按键以对地址编码和串联个数值进行加减操作，虽然能实现设定，但与多位拨码开关的拨码操作相比，本设定方式较为复杂。
主控模块200可以是具有一微处理器和输出信号转换电路的控制电路，当一个LED显示模组中的所有相互并联的LED显示装置均串联有相同数量的LED显示装置时，其根据设定模块100所设定的预设地址编码和预设串联个数值以地址编码递增方式从首个LED显示装置开始一直到最后一个LED显示装置进行一次性自动写码操作；当LED显示模组中的各个相互并联的LED显示装置所串联的LED显示装置的数量不完全相同或完全不同时，则需要由用户分次通过设定模块100设定地址编码和串联个数值后，主控模块200每一次只对相互并联的LED显示装置中的一个LED显示装置以及与之串联的LED显示装置进行写码操作。其中的输出信号转换电路主要是对微控制器所输出的写码信号转换成RS485信号、5V至12V的TTL信号并输出至LED显示装置以实现写码操作。
发光提示驱动模块300可以是用于驱动LED发光的驱动电路，当LED显示装置写码成功时，驱动LED显示装置中的LED以第一颜色（如绿色）进行发光提示，当LED显示装置写码失败时，驱动LED显示装置中的LED以第二颜色（如红色）进行发光提示或者控制LED显示装置中的LED不发光。
显示模块400可以是LCD显示屏或者LED显示屏。
对于本发明所提供的地址编码写入系统，其实现方式并不仅限于上述两种，在其他实现方式中，也可以在具有多位拨码开关的情况下采用LCD显示屏或者LED显示屏对地址编码和串联个数值进行显示。
图9示出了本发明另一实施例提供的LED显示装置的地址编码写入系统的模块结构，为了便于说明，仅示出了与本发明相关的部分，详述如下：
本实施例提供的LED显示装置的地址编码写入系统包括设定模块110和主控模块210，设定模块110和主控模块210与图7所示的设定模块100和主控模块200相同，因此不再赘述。另外，本实施例所提供的地址编码写入系统还包括：
显示驱动模块310，用于当LED显示模组中的LED显示装置成功写入地址编码时，驱动所LED显示模组的外接显示介质对当前的地址编码进行显示。
在实际应用中，显示驱动模块310可以是显示介质的驱动电路，其对包含LED显示模组的灯具中所配备的LED显示屏、LCD显示屏或者多个LED所组成的显示阵列等显示介质进行驱动以显示已成功写入LED显示装置的地址编码。
在本发明另一实施例中，如图10所示，地址编码写入系统还包括：
显示模块410，用于对预设地址编码和预设串联个数值进行显示。
本发明实施例通过在一个LED显示模组中的所有相互并联的LED显示装置均串联有相同数量的LED显示装置时，根据预设地址编码和预设串联个数值以地址编码递增方式，从首个LED显示装置开始依次对与所述首个LED显示装置相并联的一个或多个LED显示装置以及与所述一个或多个LED显示装置中的每一个LED显示装置相串联的LED显示装置进行地址编码写入操作，实现了对LED显示装置的一次性写码操作，不必再逐一对LED显示装置进行写码，进而提升了写码效率。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
