一种链路设备及链路设备通信地址配置方法
本申请要求于2020年7月1日提交中国专利局、申请号为202010627184.X、发明名称为“一种链路设备及链路设备通信地址配置方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及设备通信领域，特别涉及一种链路设备及链路设备通信地址配置方法。
背景技术
采用链路通信方式的数据中心包括上层监控设备与作为采集器的链路式设备，上层监控设备与链路式设备通信过程中，使用总线方式的通信链路，并通过链路式设备首尾相连的方式来完成通信链路部署，通信方式可以为网络通信或串口通信，对应地，上层监控设备与各个链路式设备进行通信时，需要IP地址或串口通信地址。
目前采用手动设置IP地址或者手动设置拨码开关的方式，从而手动记录每个链路式设备的物理位置和IP地址或串口地址的对应关系。当这种通信方式的链路式设备数量随着数据中心规模的扩张而逐渐增加时，现场的部署和记录的难度也急剧增加，并且后期运维人员需要人为的根据物理地址/IP地址连接和拨码方式来追朔。
如图1a所示，为通过网络通信链路连接链路设备的方式示意图，需要逐个将链路设备连接电脑设置IP，或者动态分配IP地址，完成后需要逐个查看IP地址。部署时人为的干预因素过多，容易出现错误，且地址冲突需要排查，整个过程对人员的技术要求较高；逐个查看链路设备的IP地址并匹配对应物理位 置，运维时需要查询IP地址来匹配位置，维护识别困难。
如图1b所示，为通过串口通信连接链路设备的方式示意图，现场多个链路设备需要逐个进行现场拨码设置，再逐个查看拨码地址然后对应物理位置，拨码错误时需要进行反复调整，提升了部署设备的复杂度；拨码开关属于二进制类型的开关，多位开关二进制在计算时难度较大容易出错，且一旦地址重复后排查的难度高，部署、调测过程对人员要求也较高；后期运维链路设备时需要匹配拨码地址与上层监控设备的地址，维护识别困难。

为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
现有的链路网络中，链路设备通常使用总线的方式建立通信链路，采取首尾相连的方式完成通信链路部署，其中通信链路可以为网络通信或串口通信，传统的方式采用人为手动设置IP地址或者手动设置拨码开关，从而通过手动记录每个链路设备的物理位置和通信地址对应关系，但随着链路网络中链路设备的设备数量逐渐增多，现场的部署难度也急剧增加，采用人工现场部署的方式，存在当地址设置时容易出现冲突或人工进行地址编码难度大的问题。
如图2所示，所述链路式系统中包括：监控设备201、链路设备202，其中 监控设备201通过网络方式或串口方式与各链路设备进行通信，所述网络方式通信可以为：监控设备201根据各链路设备的IP地址寻找链路设备202并与链路设备202建立通信连接，所述串口方式可以为：在每个链路设备在链路网络中都存在一个2进制的串口地址，监控设备201根据各链路设备的串口地址寻找链路设备202，监控设备201通过匹配拨码地址确定链路设备202的通信位置并与链路设备202建立通信连接。
为了解决上述链路系统中普遍存在的部署维护复杂度高、维护识别困难且对现场人员要求高的问题，如图3所示，本发明实施例提供一种链路设备，应用于上述链路式系统中，所述链路设备包括如下电路：
点名信号识别电路301，用于识别是否从上级设备接收到点名信号。
其中，本实施例中的点名信号用于确定当前链路设备是否被监控设备点名，点名到的链路设备将该设备地址修改。然后控制该链路设备点名下级设备，点名信号将被传递至链路的下级设备，该设备的物理位置和通信地址将被对应确定并存储在监控设备中以完成地址配置。依此类推，整个链路网络中各链路设备将逐个被点名后配置通信地址，从而完成整个链路的物理位置的确定及通信地址的匹配。
具体的，可以通过内部电路结构上的电平高低变化实现点名信号的触发，也可以通过通信链路中数据的传递的进行点名信号的触发，同样可以通过电源开关开断时的脉冲电流进行点名信号的触发，例如，监控设备向连接的第一个链路设备发送高电平信号，链路设备根据接收到的电平信号高低确定是否触发默认地址更改指令，利用点名信号识别电路301确定接收到的上级设备发送的信号或数据信息是否为点名信号，以将该信息发送给主控电路，本领域技术人员可以采用各种方式识别接收到的信号或数据信息是否为点名信号，本领域人员应当知晓，这里不做限定。
因链路网络的级联的链路结构，当需要向链路上第一个设备发送点名信号时，由监控设备发送向链路设备发送点名信号，并驱动所述链路设备进行当前地址修改；当本设备不是链路上第一个设备时，该链路设备接收级联的上级设 备发送的设备点名信号，进行当前地址修改。
点名信号发送电路302，用于在主控电路的控制下向下级设备发送点名信号。
当本设备在接收到地址修改指令完成通信地址配置后，接收主控电路发送的发送点名信号的指令，向级联的下级链路设备发送所述设备点名信号，所述设备点名信号同样可以通过内部电路变化的电平高低实现，也可以通过信号内传递的数据信息进行信号传输，同样可以通过开关开断时的脉冲电流进行信号传输，例如，向连接的下级链路设备发送高电平信号，级联的下个链路设备根据接收到的电平信号高低确定是否触发默认地址更改指令。

主控电路304，用于在所述点名信号识别电路识别到点名信号时，对当前地址进行预设逻辑运算得到临时地址，通过数据通信电路接收到来自监控设备的地址修改指令，根据所述地址修改指令完成通信地址配置后，控制所述点名信 号发送电路向下级设备发送点名信号。
在所述点名信号识别电路识别到点名信号时，将本设备的当前地址修改为临时地址，并根据数据通信电路接收的地址修改指令，将本设备的通信地址进行配置，并控制点名信号发送电路向下级设备发送点名信号。
在每个链路设备中，存在一个出厂时默认设置的地址，当确定链路设备接收到点名信号时，将当前地址修改为临时地址，监控设备根据临时地址连接的链路设备，在本设备的当前地址修改之后，因修改后的地址为临时地址，故当前的链路设备可以根据临时地址和监控设备建立连接，在与监控设备建立连接后，监控设备根据识别到临时地址的次数配置的通信地址，确定在本链路网络中该链路设备的对应通信地址，例如，每个设备出厂地址为A(例如A＝255)，第一个设备自身若识别到设备点名信号为电平为高电平1后，将自身地址改为临时地址A-1(254)，监控设备在组网时每次都与地址为254的链路设备进行通信，确定该链路设备为第一次出现的使用链路通信通用地址的设备时，将该设备改为地址1，即该设备被识别为第一个物理位置的设备。
其中，所述数据通信电路与监控设备通过如下至少一种方式建立通信：网络、串口、控制器局域网络CAN、串行外设接口SPI、通用串行总线USB和两线式串行总线IIC方式，其他的本领域人员能够想到的连接建立方式，均可以用于本链路设备中，这里不做限定，本领域人员应当知晓。
作为一种可选的实施方式，所述根据数据通信电路接收的地址修改指令，将本设备的通信地址进行配置，包括：
当设备采用网络链路通信时，若该链路设备为第一个物理位置的链路设备时，根据所述通信地址修改本设备为IP类型的通信地址，收到将该地址的修改为xx.xx.xx.1的IP地址指令；
当设备采用串口链路通信时，若该链路设备为第一次出现的使用链路通信通用地址的设备时，根据所述通信地址修改本设备为串口类型的通信地址，收到将该地址的修改为1的二进制串口地址指令；
将本设备通信地址修改后，监控设备在下次与链路设备通信时，基于修改 后的通信地址，与链路设备建立通信连接。
作为一种可选的实施方式，链路设备中还包括点名信号判定电路，与所述主控电路连接，用于确定所述点名信号识别电路是否识别到点名信号。
此种方式下，点名信号判定电路用于替代主控电路确定是否识别到点名信号。
作为一种可选的实施方式，所述点名信号判定电路与所述点名信号识别电路集成在同一电路中，或者与所述主控电路集成在同一电路中。
当点名信号判定电路与所述点名信号识别电路集成在同一电路中时，点名判断电路在接收到点名信号后，根据接收的点名信号确定是否触发通信地址配置准备，当触发通信地址配置准备时，将通信地址配置准备指示给主控设备，以使主控设备进行当前地址的更改；
当点名信号判定电路与主控电路集成在同一电路中，点名判断电路在接收到点名信号后，将待识别的点名信号发送到主控设备中，由主控设备根据接收的点名信号确定是否触发通信地址配置准备，当触发通信地址配置准备时，进行当前地址的更改。
作为一种可选的实施方式，所述对当前地址进行预设逻辑运算得到临时地址，包括：
对当前地址增大预设大小或减小预设大小得到临时地址，当触发通信地址配置准备后，需要将当前地址修改为临时地址，其中，修改的临时地址可以根据预设的规则，将所述当前地址增大预设大小或减小预设大小得到临时地址，如原地址为A(255)，将当前地址增大预设大小或减小预设大小，修改为A+N或A-N，其中修改的临时地址以不影响后续通信设置为前提，在监控设备侧和链路设备侧设置了相同的临时地址后，监控设备就可以通过临时地址和链路设备进行通信，因此，将当前地址逐个修改为一个无设备占用的公用地址，也是一种可选的实施方式，本领域技术人员应当知晓，这里不再赘述。
作为一种可选的实施方式，链路设备上还包括：LED显示模块，用于在配置完本设备的通信地址之后，驱动LED显示模块中的LED灯发光，以使链路设 备的使用者能够清楚知晓，该链路设备是否已经被监控设备配置了通信地址，并将该通信地址存储在地址池中。
其中，上述链路设备可以通过链路设备的内部结构改变，而以不同方式接收并向级联的设备发送设备点名信号：
方式一、点名信号识别电路为电源开关控制电路，点名信号发送电路为向下级设备输出电源开断信号的电路。
此种方式下，链路设备中包括电源开关控制电路和向下级设备输出电源开断信号的电路，接收级联的上级设备发送的电源开断信号，并在修改本设备通信地址后，向级联的下级设备发送的电源开断信号。
具体的，电源开断装置使用控制电源的方式，发送电源开断信号，在需要向下级设备发送的电源开断信号时，将本链路设备的电源断开，此时由于本设备的电源被切断，下级设备会收到因电源断开而产生的电源开断信号，下级设备能对应的修改当前地址为临时地址，并接受监控设备发送的地址修改指令，以实现通过开关链路设备电源来逐个对链路设备的通信地址进行配置。
如图4a所示为一进一出非总线方式使用电源开关控制电路的原理示意图，如图4b所示为总线式通信链路方式电源开关控制电路的原理示意图。
上述两种方式均为采用电源开关控制电路发送点名信号的方式，其区别在于，监控设备与各链路设备的数据通信电路的通信方式不同。
方式二、点名信号识别电路为与上级设备连接的数据通信支路，点名信号发送电路为向下级设备输出预设数据的数据通信支路。
具体的，链路设备中的点名信号识别电路和点名信号发送电路为使用数据通信方式连接的电路而非开关信号或脉冲，且每个链路设备的数据通信支路仅与级联的或邻近的链路设备的数据通信支路进行通信，级联的链路设备的数据通信支路通过向级联的下级设备发送的预设数据。
此种情况下，由点名信号判定电路，与所述主控电路连接，用于确定所述点名信号识别电路是否识别到点名信号，在本方式中，点名识别电路为数据通信支路，所述点名信号判定电路与数据通信支路集成在同一电路中，其中数据 通信电路和数据通信支路可以使用一种物理接口的不同线缆，也可以分为两个独立接口，这里不做限定。
下级设备通过点名信号判定电路对所述预设数据进行解析，确定预设信息是否指示为点名信号。
作为一种可选的实施方式，所述预设数据，包括如下至少一种：网络数据、串口数据、USB数据、IIC数据、SPI数据、CAN数据、单总线1-Wire数据、数字量数据、模拟量数据，链路设备的数据通信支路通过对预设数据解析，确定是否将当前地址修改为临时地址；
如图5a所示为一进一出非总线方式使用数据通信支路点名的原理示意图，如图5b所示为总线式使用数据通信支路点名的原理示意图。
上述两种方式均为采用数据通信电路发送点名信号的方式，其区别在于，监控设备与各链路设备的数据通信电路的通信方式不同。
方式三、所述点名信号识别电路为通过开关与上级设备连接的电路，所述点名信号发送电路为向下级输出开关信号的电路，本实施例中优选的采用此种方式进行点名控制及通信地址配置。
具体的，电源开关控制电路用于识别是否存在开关量输入，而向下级输出开关信号的电路可以简化为一个开关量输入，例如电磁继电器等等电子开关，在主控设备完成本设备的通信地址分配后，将本设备的电子开关断开或闭合，下级设备根据所述电子开关的断开或闭合确定是否将当前地址修改为临时地址。
如图6a所示，为发送的开关开断信号的原理示意图。
在开始点名时，第一个设备由于前边无同类链路设备，监控设备将默认高电平1的点名信号发送到第一个链路设备上，其他链路设备由于都连接在未配置通信地址的链路设备上，故默认接收到0的点名信号；
每个设备出厂默认地址为A(255)，第一个设备若接收到点名信号电平为高电平1后，将当前地址改为临时地址A-1(254)；
上层监控设备在组网地址分配时，每次都与临时地址进行通信，例如链路 通信通用地址为254，由于该设备的地址254第一次出现，通信后将该设备改为地址1，即该设备被识别为第一个物理位置的设备，通信地址为1(IP类型为通信地址为xx.xx.xx.1，串口类型通信地址为1)；
监控设备将与第一个设备建立通信，并将通信地址更新进链路设备的地址池，给配置完通信地址的链路设备下发控制要求点名该设备的下级设备，针对到被通知的链路设备上，即为使链路设备的K1断开，该断开K1的动作即为通信地址配置准备动作，会使得下级设备识别到高电平1的点名信号；
如此类推，链路网络上的多个设备逐个根据链路物理位置被设置为相应的通信地址，并将通信地址更新进地址池。
作为一种可选的实施方式，采用如图6b所示的部署点POD产品，上述点名信号识别电路及点名信号发送电路集成在该POD设备上，通过将该POD产品安装在链路设备上实现控制点名的功能。
此外，在方式三的基础上，使用集成了POD产品的链路设备，能够对至少一行的链路设备进行点名控制，例如，POD间采用二维行列类型的矩阵网络级联，即所述链路设备的网络连接方式为首尾级联，但在物理空间上的布局位置为多行矩阵形式的布局方式，若需要确定所述链路设备所在的行，需要首先确定当前的链路通信方式，并通过采用外加接口链路的方式，对各行的链路设备进行点名，根据外加接口的不同以及临时地址的出现次数，实现链路设备的行列位置识别。
具体的，点名信号识别电路和点名信号发送电路采用第一接口协议，采用第二接口协议的数据通信电路，用于将监控设备下发的控制指令传输到对应的完成通信地址配置的链路设备，及将完成通信地址配置的链路设备采集的数据上传到所述监控设备。
所述第一接口协议与第二接口协议采用的通信协议不同，其中，第一接口协议和第二接口协议中的至少一个接口的接口信号可以为：开关量信号、电源开关信号、USB、SPI、IIC等等通信信号。
例如，如图6c所示，当前数据通信电路采用网络方式进行首尾级联，由监 控设备同时使用两路RS485总线分别连接A、B列链路设备，为了对至少两行上的链路设备进行点名；
在触发链路设备点名指令时，同时向地址配置的起始A链路设备和B链路设备发送点名信号，由于A、B行链路设备分别使用两路不同的RS485总线进行点名，监控设备可以根据不同接口引出的RS485总线确定连接的设备处于的行位置；
监控设备分别通过两路不同的RS485总线向A、B行链路设备发送点名信号，在链路设备接收到点名信号后，修改本设备的当前地址为临时地址，监控设备根据RS485总线确定链路设备的行位置，根据识别到临时地址的次数确定链路设备所在的列位置，根据所述行位置和列位置给链路设备配置通信地址，将携带配置的通信地址的地址修改指令，通过所述链路发送给各路所述采用临时地址的链路设备，链路设备根据所述携带行列位置的地址修改指令配置本地通信地址。
方式四、点名信号识别电路为在数据通信电路上连接开关的电路，点名信号发送电路为在数据通信电路上向下级设备输出开关信号的电路。
本方式中，如图7所示，点名信号识别电路和点名信号发送电路设置在数据通信电路的通信链路上，通过数据通信电路上的控制数据通信的连接开关的电路，确定是否向下级链路设备发送通信数据，下级链路设备通过识别通信数据的传输状态确定是否触发了通信地址配置准备，其中，数据通信电路的数据通信传输采用电子开关器件控制，当电子开关器件闭合时，控制本链路设备向下级设备发送通信数据，当电子开关器件断开时，停止向下级设备发送通信数据，下级链路设备根据通信数据流的传输状态确定是否触发了通信地址配置准备。
利用本发明提供的一种链路设备，可以不局限于通信方式，适合于网络、串口等任意通信方式的通信链路场景，级联通信链路内链路设备的物理位置顺序可获取，并且不需要人为干预，完全免去配置环节，可自行实现物理位置和地址匹配的自组网机制，解决了在链路设备部署和运维过程中需要人工对链路 设备逐个进行配置及物理位置匹配过程过于繁琐复杂的问题，取而代之，完全由设备自动配置和位置匹配。降低了现场系统集成、监控配置和调试的工作量。
