Description

光网络设备 技术领域
本申请涉及光通信技术领域，尤其涉及一种光网络设备。
背景技术
光分配网络(Optical distribution network，ODN)为光线路终端(Optical line terminal,OLT)和光网络终端(Optical network terminal,ONT)之间提供光传输物理通道。
在ODN中，通常需要对光缆中的光纤进行分光，以覆盖更多的用户。例如，从OLT出来的光信号依次经由光配线架(Optical Distribution Frame，ODF)、光缆接头盒(splitting and splicing closure,SSC)、分光设备、光纤终端盒(access terminal box,ATB)后到达ONT。
比如，以光纤分纤箱FAT为例，每个用户在开通数据业务时(比如家里需要开通宽带业务、WIFI等)，各用户分别需要一根入户光缆，该入户光缆一段插入到FAT的光缆端口上，另一端连接到用户家里。每个FAT上一般会布置多个光缆端口，且连接有多根光缆。由于ODN是一个无源网络，每个节点设备本身不具备管理和维护功能，因此只能依靠施工人员来记录每一个光缆端口与光缆之间的对应关系，导致错误率较高。且运营商每年都要投入人力对ODN的资源进行重新梳理，施工人员要在现场对每一个设备上的端口和连接至端口上的光缆之间的连接关系等进行人工录入，不仅人力成本较高，且人为的误操作、遗漏等问题也不可避免。

在一些可能的设计中，所述壳体、所述端口和所述适配器中的至少一个设有拍摄方向指示结构，用于指示所述拍摄方向。所述拍摄方向指示结构包括凸出结构、凹陷结构、颜色标识、图案标识中的至少一种。通过设置拍摄方向指示结构，更加有利于施工人员快速获知第一拍摄方向，避免拍摄出无效的现场图像(例如某个光纤连接器上的第一识别区域全部被遮挡)，进一步提高施工效率和准确度。
在一些可能的设计中，所述壳体、所述端口和所述适配器中的至少一个设有安装指示结构，所述安装指示结构用于指示所述光纤连接器安装至所述端口上的位置、角度中的至少一种。安装指示结构有利于施工人员快速、准确且牢固的将光纤连接器安装至适配器上。另一方面，通过对现场图像进行识别，还可以识别出该安装指示结构是否与连接器指示结构匹配，进而识别出该光纤连接器是否正确安装至适配器上。
在一些可能的设计中，所述光网络设备还包括所述光纤连接器和连接至所述光纤连接器上的所述光缆。
在一些可能的设计中，所述适配器、所述端口、所述壳体的靠近各个适配器的区域中的至少一种设有第二识别区域，所述第二识别区域用于标识各个所述端口或所述适配器。所述第二识别区域包括条形码、二维码、颜色标识、图案标识、结构标识中的至少一种。上述拍摄的现场图像还可以包括各个端口对应的第二识别区域的成像，进而通过对现场图像中的各个第二识别区域进行识别，可以自动获知各个端口对应的端口标识。
在一些可能的设计中，所述壳体上还设有设备识别区域，所述设备识别区域用于指示所述光网络设备的属性信息。所述属性信息包括光网络设备的名称、标识号、编号、生产日期、端口排布方式中的至少一种。通过对现场图像上的设备识别区域进行识别，可以直接获得设备标识号以及端口排布方式，进而施工人员不需要手动输入设备标识号，在上述实施例的基础上，最终可以自动获得设备标识号、端口标识号、光纤连接器标识号之间的对应关系。更有利于施工效率以及自动化的实现。

本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列产品或设备不必限于清楚地列出的那些结构，而是可包括没有清楚地列出的或对于这些产品或设备固有的其它结构，本申请中所出现的结构的举例，仅仅是一种逻举例说明，实际应用中实现时可以有另外替换的结构，例如多个部件可以结合成或集成在另一 个结构中，或一些结构特征可以忽略，或不执行，另外，所显示的或讨论的相互之间的耦合或直接耦合，可以根据实际的需要选择其中的部分或全部结构来实现本发明实施例方案的目的。
本发明实施例提供了一种光网络设备，用于光通信领域，例如ODN领域、PON领域中的ONT。本申请中的光网络设备例如可以是但不限于光纤分纤箱(fiber access terminal，FAT)、光缆接头盒、光纤终端盒、光网络终端、光配线架等设备。其中，光配线架例如用于光纤通信系统中局端主干光缆的成端和分配，可方便地实现光纤线路的连接、分配和调度。光纤分纤箱位于光接入网络中的用户接入点，实现配线光缆与入户光缆的接续、光纤的直通、分歧和保护功能，内部可以设置分光器等。光缆接头盒可以为支持人/手孔安装的户外型产品，主要应用于光接入网络的用户接入点，实现光缆的接续与分歧及用户端入户光缆的引入等功能。光纤终端盒是用来连接入户光缆与户内ONT的无源设备，安装在用户的内墙，为户内ONT提供光纤插口。
可以理解的是，上述光网络设备可以为ODN中的任意一个节点上的设备，不限于上述，具体的名称本申请不作限定。
在一实施例中，参照图1至图3，该光网络设备包括壳体1，所述壳体1上设有至少一个端口11，所述光网络设备还包括安装于所述端口11上的至少一个适配器2，所述适配器2用于连接光纤连接器31，所述光纤连接器31上连接有光缆32，且所述光纤连接器31的外侧面或光缆32的外侧面设有第一识别区域311，所述第一识别区域311用于标识所述光纤连接器31或光缆32。可以理解的是，本申请文件中的光缆，可以为市面上销售的较粗的光缆(内部含有若干根光纤，每根光纤外侧有塑胶包皮)，也可以为其内部的较细的带有塑胶包皮的光纤。
第一识别区域311包括但不限于条形码、二维码、颜色标识、图案标识、结构标识中的至少一种。该条形码、二维码、颜色标识、图案标识等可以是印好的标签粘贴到光纤连接器31的外侧或光缆32的外侧，也可以直接打印到光纤连接器31外侧或光缆32外侧，或者通过其他工艺(如激光雕刻)在光纤连接器31外侧或光缆32外侧雕刻成型，或者通过丝印方式。颜色标识例如可以为不同颜色的色条组合在一起的标识区域(不同颜色的色条按照不同顺序组合，进而指示不同的标识)。图案标识例如可以为与标识一一对应的图形，或者为标识号。该结构标识可以为凸出结构、凹陷结构等，凸出结构例如可以为凸点、凸线、凸块等。该凹陷结构可以为凹点、凹陷、凹槽等。
在一实施例中，第一识别区域311指示光纤连接器31或光缆32的标识号。由于一个光纤连接器31上连接一根光缆32，因此第一识别区域311指示光纤连接器31的标识号时，也可以唯一的标识光缆32；第一识别区域311指示光缆32的标识号时，也可以唯一的标识光纤连接器31。因此指示光纤连接器31和指示光缆32是等同的，都是表示同一条光纤链路。
每一所述光纤连接器31或光缆32标识号可以唯一标识在一定区域范围内的光纤连接器31或光缆32。一定区域范围例如可以理解为同一个OLT下的或者一定地域范围内的所有光纤链路上的光纤连接器31或光缆32。
手持终端通过拍摄该光网络设备，生成现场图像，现场图像中包括第一识别区域311 的成像，通过对现场图像进行图像识别，可以识别出第一识别区域311，进而识别出光纤连接器31或光缆32对应的标识码。
在一实施例中，第一识别区域311为环绕于所述光缆32外侧的环形区域。从而更加有利于在至少一个角度同时拍摄到光网络设备上的所有光缆32或光纤连接器31上的第一识别区域311。可以理解的是，环形区域可以为不间断的，更有利于在至少一个角度同时拍摄到光网络设备上的所有光缆32或光纤连接器31上的第一识别区域311；也可以为间断的有利于节约印刷或制作第一识别区域311的成本。
各个所述端口11之间相互错开排布，安装于各个所述端口11上的各个所述适配器2之间相互错开排布，且安装至各个所述适配器2上的各个所述光纤连接器31之间相互错开排布，使得至少存在第一拍摄方向，在所述第一拍摄方向上可以拍摄到各个所述光纤连接器31上或所述光缆32上的所述第一识别区域311。
在本实施例中，相互错开排布的方式有很多种。以第一识别区域311设置在光纤连接器31为例，能存在至少一个第一拍摄方向，该拍摄方向为可以拍摄到光纤连接器31外侧壁的方向，进一步讲，该拍摄方向为可以拍摄到光纤连接器31外侧的第一识别区域311的方向。可以理解的是，拍摄方向一般为垂直于或大致垂直于光纤连接器31内光传播通道的方向。因此，各个端口11之间，能够使得至少存在上述一个拍摄方向的排布方式，都可以称为相互错开排布。例如，各个所述端口11之间可以呈但不限于单排排布，或W形排布，或V形排布，或S形排布。此外，如图1和2所示，各个端口11之间还可以呈双排排布。
可以理解的是，适配器2安装到端口11上，且光纤连接器31安装在适配器2上，在端口11之间相互错开排布时，适配器2之间也可以相互错开排布，进而光纤连接器31之间也相互错开排布。且至少存在第一拍摄方向，使得在该拍摄方向上，可以一次性拍摄到安装到端口11上的光纤连接器31或光缆32上的第一识别区域311，因此所拍摄的现场图像中包括每个安装了光纤连接器31所对应的第一识别区域311，可以对第一识别区域311进行图像识别，获取各个光纤连接器31或光缆32所对应的标识号。并且通过对现场图像进行识别，例如可以获得各个端口11的位置(如第一排第一个位置，第二排第三个位置等)。通过对现场图像进行识别，可以获知各个端口11位置所插接的光纤连接器31，进而确定各个位置的端口11所对应插接的光纤连接器31的标识号，即最终获取各个端口11标识(如一个光网络设备上的每个端口11的位置不同，可以视为端口11标识)与各个光纤连接器31标识之间的对应关系。
或者，在另一实施例中，所述适配器2、所述端口11、所述壳体1的靠近各个适配器2的区域中的至少一种设有第二识别区域(图中未标示)，所述第二识别区域用于标识各个所述端口11或所述适配器2。所述第二识别区域包括条形码、二维码、颜色标识、图案标识、结构标识中的至少一种，条形码、二维码、颜色标识、图案标识、结构标识具体可参照上述实施例，在此不再赘述。每个第二识别区域，可以标识一个端口11标识。上述拍摄的现场图像还可以包括各个端口11对应的第二识别区域的成像，进而通过对现场图像中的各个第二识别区域进行识别，可以获知各个端口11对应的端口11标识。
可以理解的是，对于每个光纤连接器31上第一识别区域311，现场图像可以不呈现该光纤连接器31上的全部第一识别区域311，可以只呈现部分第一识别区域311，只要能够 根据现场图像上的第一识别区域311能够正确识别出该光纤连接器31的标识号即可。
现有技术中，以光纤分纤箱FAT为例，每个用户在开通数据业务时(比如家里需要开通宽带业务、WIFI等)，各用户分别需要一根入户光缆32，该入户光缆32一段插入到FAT的光缆32端口11上，另一端连接到用户家里。每个FAT上一般会布置多个光缆32端口11，且连接有多根光缆32。由于ODN是一个无源网络，每个节点设备本身不具备管理和维护功能，因此只能依靠施工人员来记录每一个光缆32端口11与光缆32之间的对应关系，导致错误率较高。且运营商每年都要投入人力对ODN的资源进行重新梳理，施工人员要在现场对每一个设备上的端口11和连接至端口11上的光缆32之间的连接关系等进行人工录入，不仅人力成本较高，且人为的误操作、遗漏等问题也不可避免。
本实施例提供的光网络设备，能够有助于施工人员拍照获取现场图像，进而根据现场图像可以自动获得各个端口11标识与各个光纤连接器31的标识号之间的对应关系，进而现场施工人员不需要在施工时，手动记录每一个光缆32端口11与光缆32之间的对应关系，直接按照第一拍摄方向进行拍照即可。不仅人力成本低，施工效率高，且准确度也高。
在一实施例中，所述壳体1、所述端口11和所述适配器2中的至少一个设有拍摄方向指示结构1212，用于指示所述第一拍摄方向。所述拍摄方向指示结构12包括凸出结构、凹陷结构、颜色标识、图案标识中的至少一种。该拍摄方向指示结构12可以设于壳体1的正面、侧面等。
在一实施例中，如图2所示，该拍摄方向指示结构12可以设置于设有端口11的侧壁上，从而更有利于指示拍摄方向。拍摄方向指示结构12例如可以为箭头(如图2)、文字等。具体可以通过上述凸出结构、凹陷结构、图案标识等呈现。通过设置拍摄方向指示结构12，更加有利于施工人员快速获知第一拍摄方向，避免拍摄出无效的现场图像(例如某个光纤连接器31上的第一识别区域311全部被遮挡)，进一步提高施工效率和准确度。
在一实施例中，所述壳体1、所述端口11和所述适配器2中的至少一个设有安装指示结构1313，所述安装指示结构13用于指示所述光纤连接器31安装至所述端口11上的位置、角度中的至少一种。在一实施例中，光纤连接器31上也可以设置一连接器指示结构，该连接器指示结构与上述安装指示结构13配合，例如，将连接器指示结构与安装指示结构13对准时，则光纤连接器31可以正确安装。因此安装指示结构13有利于施工人员快速、准确且牢固的将光纤连接器31安装至适配器2上。另一方面，通过对现场图像进行识别，还可以识别出该安装指示结构13是否与连接器指示结构匹配，进而识别出该光纤连接器31是否正确安装至适配器2上。
在一实施例中，如图4所示，所述端口11包括凸出于所述壳体1外侧的端口侧壁111，所述安装指示结构13为设于所述端口侧壁111上的开槽(如图4，可以为V形槽，此外还可以为矩形槽，C形槽等)、刻度线、凸出结构、凹陷结构、颜色标识、图案标识中的至少一种；光纤连接器31外侧壁也可以设置与安装指示结构13对应的凸出结构、箭头标识、凹陷结构、颜色标识、图案标识等，在安装指示结构13与光纤连接器31外侧的连接器指示结构对准时，则表明光纤连接器31正确安装。
或者所述安装指示结构13为设于所述适配器2外侧的凸出结构、凹陷结构、颜色标识、图案标识中的至少一种。其中，凸出结构、凹陷结构、颜色标识、图案标识中可以参照上 述实施例，在此不再赘述。
在一实施例中，所述光网络设备还包括上述光纤连接器31和连接至光纤连接器31上的所述光缆32。
在一实施例中，如图1和图3所示，所述壳体1上还设有设备识别区域14，所述设备识别区域14用于指示所述光网络设备的属性信息。所述属性信息可以包括但不限于光网络设备的名称、标志号、编号、生产日期、端口11排布方式中的至少一种。该设备识别区域14可以设置于壳体1的沿上述第一拍摄方向的正面，进而使得在沿第一拍摄方向拍摄时，更有利于从正面拍摄到设备识别区域14。通过对现场图像上的设备识别区域14进行识别，可以直接获得设备标识号以及端口11排布方式，进而施工人员不需要手动输入设备标识号，在上述实施例的基础上，最终可以自动获得设备标识号、端口11标识号、光纤连接器31标识号之间的对应关系。更有利于施工效率以及自动化的实现。
在一实施例中，如图3所示，壳体1上还可以设置图像识别辅助结构15，用于辅助对现场图像识别，如以正确的方向识别。图像识别辅助结构15例如可以为条形码、二维码、颜色标识、图案标识、结构标识中的至少一种。具体可参照上述实施例，在此不再赘述。在一个例子中，如图3所述，图像识别辅助结构15可以为3个凸块，呈L形排布。进而在图像识别中，以L形为正向进行识别。
图像识别辅助结构15例如可以设置于壳体1的沿上述第一拍摄方向的正面，进而使得在沿第一拍摄方向拍摄时，更有利于从正面拍摄到图像识别辅助结构15。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
所属领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统，装置和模块的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
