Description

一种快速设置灯具DMX地址的方法 技术领域
本发明涉及照明技术领域，更具体地，涉及一种快速设置灯具DMX地址的方法。
 背景技术
当需要大批量地修改灯具DMX地址时，现有的灯具地址设置方法需要在灯具的控制面板或通过RDM功能逐个进行设置，费时费力，效率低下。
申请号为CN201710805203.1的专利中提出了一种基于灯具控制系统的灯具地址配置方法与装置，通过控制器自动地为系统中的每个灯具设置一个编号，并且最终通过用户自定义的范围性编号给灯具设置起始地址。该灯具地址设置方法具有以下缺点：
1、用一条数据线单向传输来分配DMX地址的，数据传输的效率和可靠性较低；
2、灯具每次通电后都会给回路中的灯具分配一次DMX地址，假如用户希望回路中的灯具保持相同的DMX地址，则无法实现；
3、必须从第一台灯具开始向后分配DMX地址的，缺乏灵活性；
4、灯具内部需要另外安装可控开关，增加制造成本和维护成本；
5、一旦某个节点通信出现异常（例如信号线不通、灯具损坏等），则这个节点后面的正常灯具都无法分配地址。
 技术问题
本发明旨在克服上述现有技术的至少一种缺陷，提供一种快速设置灯具DMX地址的方法，可以从任一台灯具开始向后分配DMX地址，并且可以判断灯具DMX地址的设置情况。
 技术解决方案
本发明采取的技术方案是：
一种快速设置灯具DMX地址的方法，用于设置N台灯具的DMX地址，所述N台灯具通过第一信号线依次串联连接，N = 2, 3, ……，第1台灯具通过第一信号线连接有控制器，令i = 1, 2, ……, N-1，所述方法包括以下步骤：
分配步骤：
控制器通过第一信号线发送DMX地址到第i台灯具；
设置步骤：
第i台灯具将其DMX地址设置为其接收到的DMX地址，根据其接收到的DMX地址计算第i+1台灯具的DMX地址，并通过第一信号线发送第i+1台灯具的DMX地址到第i+1台灯具；
第i+1台灯具将其DMX地址设置为其接收到的DMX地址，并通过第一信号线发送反馈信号到第i台灯具；
判断步骤：
若第i台灯具在发送DMX地址后的设定时间内没有接收到第i+1台灯具发送的反馈信号，则第1个至第i台灯具分别通过第一信号线发送计数信号和/或各自的UID码和/或各自成功设置的DMX地址到控制器。
控制器可以将DMX起始地址通过第一信号线发送给任一台灯具，从而实现从任一台灯具开始向后分配DMX地址。当灯具的数量或者灯具的UID码是已知时，可以根据控制器接收到的计数信号、UID码、DMX地址，判断是否所有灯具的DMX地址均设置成功，获知成功设置DMX地址的灯具的UID码和/或DMX地址。
进一步地，所述控制器和N台灯具还通过第二信号线依次串联或并联连接，所述根据控制器通过第一信号线接收到的UID码和/或DMX地址判断灯具的DMX地址的设置情况，具体包括以下步骤：
N台灯具分别通过第二信号线发送计数信号和/或各自的UID码到控制器；
根据控制器通过第二信号线接收到的计数信号和/或UID码，获取灯具数量N’；
根据控制器通过第一信号线接收到的计数信号和/或UID码和/或DMX地址，获取成功设置DMX地址的灯具数量N”；
比较N’和N”，根据比较结果判断灯具的DMX地址的设置情况。
当灯具的数量或者灯具的UID码是未知时，可以通过第二信号线获取灯具的数量或者灯具的UID码。但是第二信号线也可能存在通信异常的情况，因此，需要比较N’和N”综合判断灯具的DMX地址的设置情况，判断第一信号线和第二信号线是否存在通信异常。
进一步地，所述根据比较结果判断灯具的DMX地址的设置情况，具体包括：
若N’= N”，则判断为N台灯具的DMX地址全部成功设置；
若N’> N”，则判断为存在灯具不能通过第二信号线与控制器通信；
若N’< N”，则判断为N台灯具的DMX地址未全部成功设置。
进一步地，所述方法还包括以下步骤：
当N’＞ N”时，比较控制器通过第二信号线接收到的UID码和控制器通过第一信号线接收到的UID码，确定不能通过第二信号线与控制器通信的灯具的UID码。
当N’＞ N”时，表明第二信号线在若干台灯具与控制器之间存在通信异常，使得通过第二信号线所统计获知的灯具数量N”比通过第一信号线所统计获知的灯具数量N’要少。此时通过比较控制器通过两组信号线接收到的UID码，可以确定第二信号线出现通信异常的位置对应的灯具UID码，以便操作人员及时对通信异常进行排除。
进一步地，所述方法还包括以下步骤：
当N’< N”时，比较控制器通过第二信号线接收到的UID码和控制器通过第一信号线接收到的UID码，确定未成功设置DMX地址的灯具的UID码。
当N’< N”时，表明第一信号线在某两台灯具之间存在通信异常，使得通过第一信号线所统计获知的灯具数量N’比通过第二信号线所统计获知的灯具数量N”要少。此时通过比较控制器通过两组信号线接收到的UID码，可以确定未成功设置DMX地址的灯具的UID码。
进一步地，所述方法还包括以下步骤：
当确定未成功设置DMX地址的灯具的UID码后，控制器根据未成功设置DMX地址的灯具的UID码，通过第二信号线发送控制指令到未成功设置DMX地址的灯具，某个未成功设置DMX地址的灯具记为第j台灯具，j = 2, 3, ……, N；
第j台灯具接收到控制指令后，通过第二信号线发送查询指令到第j+1台灯具；
第j+1台灯具接收到查询指令后，通过第二信号线发送应答指令到第j台灯具；
根据第j台灯具是否接收到查询指令和应答指令，确定第j台灯具在所有未成功设置DMX地址的灯具中的相对连接位置。
通过上述方法可以确定未成功设置DMX地址的灯具的排列顺序，从而获知第一信号线出现通信异常的具体位置，以便操作人员及时对通信异常进行排除。
进一步地，所述方法还包括以下步骤：
查找所有未成功设置DMX地址的灯具中相对连接位置在最前端的灯具，所查找到的灯具记为第x台灯具，x = 2, 3, ……, N；
控制器根据通过第一信号线接收到的DMX地址计算第x台灯具的DMX地址，通过第二信号线发送第x台灯具的DMX地址到第x台灯具；
令i = x, x+1, ……, N-1，执行所述设置步骤；
若第i台灯具在发送DMX地址后的设定时间内没有接收到第i+1台灯具发送的反馈信号，则第x个至第i台灯具分别通过第一信号线发送各自的UID码和/或成功设置的DMX地址到第x台灯具，第x台灯具通过第二信号线将接收到的UID码和/或DMX地址转发到控制器。
当查找到所有未成功设置DMX地址的灯具中排在最前端的灯具后，可以结合第一信号线和第二信号线，继续对未成功设置DMX地址的灯具进行DMX地址的设置。
进一步地，所述方法还包括以下步骤：
第i台灯具将其DMX地址设置为其接收到的DMX起始地址后，通过第一信号线发送反馈信号到控制器。
第一信号线也有可能在任一台起始设置的灯具与控制器之间存在通信异常，因此在该台起始设置的灯具成功设置DMX地址后也要发送反馈信号到控制器。如果控制器无法接收该台起始设置的灯具发送的反馈信号，则可以获知该台灯具与控制器之间存在通信异常，以便操作人员及时排除异常。
进一步地，所述灯具还通过RDM信号线分别与控制器连接，还包括以下步骤：
根据控制器通过第一信号线接收到的UID码和DMX地址之间的对应关系，获知连接顺序；
根据所述连接顺序，控制器通过RDM信号线分别向灯具发送DMX地址；
灯具将其DMX地址设置为通过RDM信号线接收到的DMX地址。
当灯具的DMX地址需要设置成特定的值，造成N个灯具的DMX地址需要不连续地设置时，可以通过RDM信号线将N个灯具分别与控制器连接。
如上所述，当执行完上述分配步骤、设置步骤、判断步骤后，根据控制器通过第一信号线接收到的DMX地址和UID码之间的对应关系可以获知灯具的连接顺序，根据所获知的灯具连接顺序，控制器可以通过RDM信号线直接发送DMX地址到灯具，灯具在RDM的地址设置指令下完成灯具DMX地址的设置。
进一步地，所述RDM信号线为第二信号线。

 本发明的最佳实施方式
本实施例提供一种快速设置灯具DMX地址的方法，用于设置N台灯具的DMX地址，所述N台灯具通过第一信号线依次串联连接，N = 2, 3, ……，i = 1, 2, ……, N-1，第1台灯具通过第一信号线连接有控制器，令i = 1, 2, ……, N-1，所述方法包括以下步骤：
分配步骤：
控制器通过第一信号线发送DMX地址到第i台灯具；
设置步骤：
第i台灯具将其DMX地址设置为其接收到的DMX地址，根据其接收到的DMX地址计算第i+1台灯具的DMX地址，并通过第一信号线发送第i+1台灯具的DMX地址到第i+1台灯具；
第i+1台灯具将其DMX地址设置为其接收到的DMX地址，并通过第一信号线发送反馈信号到第i台灯具；
判断步骤：
若第i台灯具在发送DMX地址后的设定时间内没有接收到第i+1台灯具发送的反馈信号，则第1个至第i台灯具分别通过第一信号线发送计数信号和/或各自的UID码和/或各自成功设置的DMX地址到控制器。
为方便描述，连接在第i台灯具与第i+1台灯具之间的第一信号线记为A（i-1，i），在具体实施过程中，A（i-1，i）和A（i，i+1）是互不相通的，A（i-1，i）和A（i，i+1）之间的数据传输是通过灯具进行转发的。
在具体实施过程中，第i台灯具根据其接收到的DMX地址计算第i+1台灯具的DMX地址，具体为：第i台灯具将其接收到的DMX地址加上其占有的通道数，得到第i+1台灯具的DMX地址。
如图1所示，以N=5为例，5台灯具通过第一信号线依次串联连接，编号为1到5，控制器通过第一信号线与第1台灯具连接。假设5台灯具均占有4个通道，初始DMX地址均为1。采用本实施例所提供的方法对5台灯具的DMX地址进行设置，DMX地址从10开始，则执行以下步骤：
（1）控制器通过A（0，1）发送DMX地址10到第1台灯具；
（2）第1台灯具在地址设置指令下将其DMX地址设置成10，并将其DMX地址10加上其所占的通道数4得到一个新的DMX地址14，通过A（1，2）将DMX地址14发送到第2台灯具；
（3）第2台灯具在地址设置指令下将其DMX地址设置成14，并通过A（1，2）发送反馈信号到第1台灯具，表明已接收到第1台灯具发送的DMX地址14；
（4）第2台灯具将其DMX地址14加上其所占的通道数4得到一个新的DMX地址18，通过A（2，3）将DMX地址18发送到第3台灯具；
（5）第3、4、5台灯具同样按照上述步骤完成DMX地址的设置，最终第1至5台灯具的DMX地址分别设置成10、14、18、22、26；
（6）由于只有5台灯具，没有第6台灯具，因此第5台灯具将DMX地址30发送出去后在设定时间内（例如50毫秒）是无法接收到下一台灯具发回来的反馈信号的，第5台灯具就会通过A（4，5）将计数信号和/或其UID码和/或其DMX地址发送到第4台灯具，第4台灯具再通过A（3，4）将第5台灯具的计数信号和/或UID码和/或DMX地址向前转发，直到发送到控制器；
（7）第4、3、2、1台灯具也会通过第一信号线依次先后将计数信号和/或其UID码和/或其DMX地址发送到控制器；
（8）当灯具的数量或者灯具的UID码是已知时，根据控制器接收到的计数信号和/或UID码和/或DMX地址的个数可以获知成功设置DMX地址的灯具数量，还可以根据控制器接收到的UID码获知哪些灯具已成功设置DMX地址，还可以根据控制器接收到的UID码和DMX地址之间的对应关系获知哪些灯具已成功设置哪个DMX地址以及编号1到5的灯具对应的5个UID码顺序，也即获知了灯具的连接顺序。
如图2所示，如果A（2，3）发生了通信异常，第2台灯具将DMX地址14发送出去后在设定时间内（例如50毫秒）无法接收到第3台灯具发回来的反馈信号，此时第1、2台灯具会依次先后将计数信号和/或其UID码和/或其DMX地址发送到控制器，由此可获知只有2台灯具——第1、2台灯具的DMX地址已成功设置，并且获知已成功设置DMX地址的灯具的UID码以及DMX地址。
控制器可以将DMX起始地址通过第一信号线发送给任一台灯具，从而实现从任一台灯具开始向后分配DMX地址。当灯具的数量或者灯具的UID码是已知时，可以根据控制器接收到的计数信号和/或UID码和/或DMX地址，判断是否所有灯具的DMX地址均设置成功，获知成功设置DMX地址的灯具的UID码和/或DMX地址。
在本实施例中，所述控制器和N台灯具还通过第二信号线依次串联或并联连接，所述根据控制器通过第一信号线接收到的UID码和/或DMX地址判断灯具的DMX地址的设置情况，具体包括以下步骤：
N台灯具分别通过第二信号线发送计数信号和/或各自的UID码到控制器；
根据控制器通过第二信号线接收到的计数信号和/或UID码，获取灯具数量N’；
根据控制器通过第一信号线接收到的UID码和/或DMX地址，获取成功设置DMX地址的灯具数量N”；
比较N’和N”，根据比较结果判断灯具的DMX地址的设置情况。
如图3所示，编号1到5的灯具通过第一信号线依次串联连接、编号1的灯具通过第一信号线与控制器连接的同时，还通过第二信号线与控制器依次并联连接；控制器可以通过第二信号线分别向5台灯具发送RDM查询灯具的指令，使得5台灯具通过第二信号线发送计数信号和/或各自的UID码到控制器，从而获知灯具数量N’；控制器通过第一信号线接收到的计数信号和/或UID码和/或DMX地址可以获知成功设置DMX地址的灯具数量N”，通过比较N’和N”可以判断灯具的DMX地址的设置情况。
在灯具的数量或者灯具的UID码是未知时，可以通过第二信号线获取灯具的数量或者灯具的UID码。但是第二信号线也可能存在通信异常的情况，因此，需要比较N’和N”综合判断灯具的DMX地址的设置情况，判断第一信号线和第二信号线是否存在通信异常。
其判断方式具体为：
（1）若N’= N”，则判断为N台灯具的DMX地址全部成功设置；
（2）若N’> N”，则判断为存在灯具不能通过第二信号线与控制器通信；
（3）若N’< N”，则判断为N台灯具的DMX地址未全部成功设置。
在本实施例中，所述方法还包括以下步骤：
当N’＞ N”时，比较控制器通过第二信号线接收到的UID码和控制器通过第一信号线接收到的UID码，确定不能通过第二信号线与控制器通信的灯具的UID码。
当N’＞ N”时，表明第二信号线在若干台灯具与控制器之间存在通信异常，使得通过第二信号线所统计获知的灯具数量N”比通过第一信号线所统计获知的灯具数量N’要少。如图4所示，连接在控制器与第3台灯具之间的第二信号线出现了通信异常，只有第1、2、4、5台灯具可以通过第二信号线将UID码发送到控制器，N”应为4，而第一信号线不存在通信异常，N’应为5，此时N’＞ N”，对比控制器通过两组信号线所获得的灯具UID码，可以确定在第二信号线上与控制器出现通信异常的第3台灯具对应的UID码。
在本实施例中，所述方法还包括以下步骤：
当N’< N”时，比较控制器通过第二信号线接收到的UID码和控制器通过第一信号线接收到的UID码，确定未成功设置DMX地址的灯具的UID码。
当N’< N”时，表明第一信号线在某两台灯具之间存在通信异常，使得通过第一信号线所统计获知的灯具数量N’比通过第二信号线所统计获知的灯具数量N”要少。第一信号线在某两台灯具之间存在通信异常，则通信异常位置之后的灯具都不能成功设置DMX地址。如图5所示，A（2，3）发生了通信异常，则第3、4、5台灯具都不能成功设置DMX地址，只有第1、2台灯具将UID码发送到控制器，N’应为2，而第二信号线不存在通信异常，N”应为5，此时N’< N”，对比控制器通过两组信号线所获得的灯具UID码，可以确定未成功设置DMX地址的第3、4、5台灯具的UID码。
在本实施例中，所述方法还包括以下步骤：
当确定未成功设置DMX地址的灯具的UID码后，控制器根据未成功设置DMX地址的灯具的UID码，通过第二信号线发送控制指令到未成功设置DMX地址的灯具，某个未成功设置DMX地址的灯具记为第j台灯具，j = 2, 3, ……, N；
第j台灯具接收到控制指令后，通过第二信号线发送查询指令到第j+1台灯具；
第j+1台灯具接收到查询指令后，通过第二信号线发送应答指令到第j台灯具；
根据第j台灯具是否接收到查询指令和应答指令，确定第j台灯具在所有未成功设置DMX地址的灯具中的相对连接位置。
所述根据第j台灯具是否接收到查询指令和应答指令，确定第j台灯具在所有未成功设置DMX地址的灯具中的相对连接位置，具体为：若第j台灯具只接收到应答指令，没有接收到查询指令，则第j台灯具在所有未成功设置DMX地址的灯具中的相对连接位置在最前端；若第j台灯具既接收到应答指令，又接收到查询指令，则第j台灯具在所有未成功设置DMX地址的灯具中的相对连接位置在中间；若第j台灯具只接收到查询指令，没有接收到应答指令，则第j台灯具在所有未成功设置DMX地址的灯具中的相对连接位置在最后端。
具体实施过程中，报告信息可以包括灯具的UID码，通过控制器接收到的报告信息，可以获知在所有未成功设置DMX地址的灯具中的相对连接位置在最前端的灯具对应的UID码。
如图5所示，A（2，3）发生了通信异常，第3、4、5台灯具都不能成功设置DMX地址，只有第1、2台灯具将UID码发送到控制器，如上所述，通过对比控制器通过两组信号线所获得的灯具UID码，确定了未成功设置DMX地址的第3、4、5台灯具这3台灯具的UID码后，并不知道哪个UID码对应的是第几台灯具，此时让控制器根据这3台灯具的UID码通过第二信号线分别发送控制指令到这3台灯具，这3台灯具接收到控制指令后，分别通过第二信号线发送查询指令到其后一台灯具，而接收到查询指令的灯具会发送应答指令到前一台灯具，也即第3台灯具发送查询指令到第4台灯具，第4台灯具接收到查询指令后发送应答指令到第3台灯具，第4台灯具发送查询指令到第5台灯具，第5台灯具接收到查询指令后发送应答指令到第4台灯具，第5台灯具也向后发送查询指令，但由于没有第6台灯具，所以第5台灯具不会接收到应答指令。由此，第3台灯具只接收到第4台灯具发送的应答指令，没有接收到其前一台灯具发送给它的查询指令，因此判断第3台灯具是在3个未成功设置DMX地址灯具中排在最前端的；第4台灯具既接收到第3台灯具发送的查询指令，又接收到第5台灯具发送的应答指令，因此判断第4台灯具是在3个未成功设置DMX地址灯具中排在中间的；第5台灯具只接收到第4台灯具发送的查询指令，没有接收到后一台灯具发送给它的应答指令，因此判断第5台灯具是在3个未成功设置DMX地址的灯具中排在最后端的。第3台灯具会通过第二信号线发送报告信息到控制器，向控制器报告自己是排在最前端的灯具。
通过上述方法可以确定未成功设置DMX地址的灯具的排列顺序，从而获知第一信号线出现通信异常的具体位置，以便操作人员及时对通信异常进行排除。
在本实施例中，所述方法还包括以下步骤：
查找所有未成功设置DMX地址的灯具中相对连接位置在最前端的灯具，所查找到的灯具记为第x台灯具，x = 2, 3, ……, N；
控制器根据通过第一信号线接收到的DMX地址计算第x台灯具的DMX地址，通过第二信号线发送第x台灯具的DMX地址到第x台灯具；
令i = x, x+1, ……, N-1，执行所述设置步骤；
若第i台灯具在发送DMX地址后的设定时间内没有接收到第i+1台灯具发送的反馈信号，则第x个至第i台灯具分别通过第一信号线发送各自的UID码和/或成功设置的DMX地址到第x台灯具，第x台灯具通过第二信号线将接收到的UID码和/或DMX地址转发到控制器。
所述查找所有未成功设置DMX地址的灯具中相对连接位置在最前端的灯具，可以具体为：若第j台灯具只接收到应答指令，没有接收到查询指令，则第j台灯具通过第二信号线发送报告信息到控制器。通过控制器接收到的报告信息，可以获知具体是哪台灯具在所有未成功设置DMX地址的灯具中相对连接位置在最前端。
] 当查找到所有未成功设置DMX地址的灯具中排在最前端的灯具后，可以结合第一信号线和第二信号线，继续对未成功设置DMX地址的灯具进行DMX地址的设置。
 如图5所示，当查找到所有未成功设置DMX的灯具中排在最前端的灯具为第3台灯具时，由于之前控制器通过第一信号线接收到了第1、2台灯具的DMX地址，根据第2台灯具的DMX地址14，加上第2台灯具所占的通道数4，即可得到第3台灯具的DMX地址18，此时执行以下步骤：
（1）控制器通过第二信号线发送DMX地址18到第3台灯具；
（2）第3台灯具在地址设置指令下将其DMX地址设置成18，并将其DMX地址18加上其所占通道数4得到一个新的DMX地址22，通过A（3，4）将DMX地址22发送到第4台灯具；
（3）第4台灯具在地址设置指令下将其DMX地址设置成22，并通过A（3，4）发送反馈信号到第3台灯具，表明已接收到第3台灯具发送的DMX地址22；
（4）第5台灯具也按上述步骤完成DMX地址的设置，最终之前未成功设置DMX地址的第3、4、5台灯具DMX地址已分别设置成18、22、26；
（5）由于只有5台灯具，没有第6台灯具，因此第5台灯具将DMX地址30发送出去后在设定时间内（例如50毫秒）是无法接收到下一台灯具发回来的反馈信号的，第5台灯具就会通过A（4，5）将计数信号和/或其UID码和/或其DMX地址发送到第4台灯具，第4台灯具再通过A（3，4）将第5台灯具的计数信号和/或UID码和/或DMX地址向前转发到第3台灯具，同理第4台灯具的计数信号和/或UID码和/或DMX地址也会发送到第3台灯具；
（6）由于A（2，3）是发生通信异常的，所以第3台灯具则会通过第二信号线将第3、4、5台灯具的计数信号和/或UID码和/或DMX地址转发到控制器；
（7）根据控制器接收到的计数信号和/或UID码和/或DMX地址，可以获知之前未成功设置DMX地址的灯具此时是否已成功设置。
在本实施例中，所述方法还包括以下步骤：
第i台灯具将其DMX地址设置为其接收到的DMX起始地址后，通过第一信号线发送反馈信号到控制器。
第一信号线也有可能在任一台起始设置的灯具与控制器之间存在通信异常，因此在该台起始设置的灯具成功设置DMX地址后也要发送反馈信号到控制器。如果控制器无法接收该台起始设置的灯具发送的反馈信号，则可以获知该台灯具与控制器之间存在通信异常，以便操作人员及时排除异常。
当灯具的DMX地址需要设置成特定的值，造成N个灯具的DMX地址需要不连续地设置时，可以通过RDM信号线将N个灯具分别与控制器连接。
如上所述，当执行完上述分配步骤、设置步骤、判断步骤后，根据控制器通过第一信号线接收到的DMX地址和UID码之间的对应关系可以获知灯具的连接顺序，根据所获知的灯具连接顺序，控制器可以通过RDM信号线直接发送DMX地址到灯具，灯具在RDM的地址设置指令下完成灯具DMX地址的设置。
如图6所示，编号1到5的灯具通过第一信号线依次串联连接、编号1的灯具通过第一信号线与控制器连接的同时，还通过RDM信号线与控制器依次并联连接。例如需要将编号为1的灯具DMX地址设置成20，编号为2的灯具DMX地址设置成1，编号为3、4、5的灯具DMX地址设置成30、34、38，在已知5台灯具的连接顺序后，就可以获知编号为1的灯具在第1台灯具处，编号为2的灯具在第2台灯具处，编号为3的灯具在第3台灯具处，编号为4的灯具在第4台灯具处，编号为5的灯具在第5台灯具处。
对于编号为1、2的灯具，控制器通过RDM信号线将第1台灯具的DMX地址设置成20，、将第2台灯具的DMX地址设置成1。
而对于编号为3、4、5的灯具，由于它们的DMX地址是连续的，所以既可以让控制器通过RDM信号线分别将第3、4、5台灯具的DMX地址设置为30、34、38，也可以控制器通过RDM信号线或者第二信号线将第3台灯具的DMX地址设置为30，第3台灯具将其DMX地址30加上4后得出一个新的DMX地址34，并将DMX地址34通过第一信号线发送到第4台灯具，第4台灯具接收到DMX地址34后将其DMX地址设置为34，将DMX地址34加上4后得出一个新的DMX地址38，并将DMX地址38发送到第5台灯具，第5台灯具接收到DMX地址38后将其DMX地址设置为38。
在具体实施过程中，所述RDM信号线为第二信号线，也即RDM信号线和第二信号线可以为同一组信号线。
在具体实施过程中，控制器与灯具之间的通信、灯具与灯具之间的通信采用485通信，所述第一信号线、第二信号线包含两条485通信总线。
