Description

一种智能ODN标识系统及装置 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种智能光配线网络(Optical Distribution Network，简称为ODN)标识系统及装置。

目前，光配线领域中，需要对大量的光纤跳纤、尾纤进行物理配线、连接，然而，如何在大量的光纤跳纤、尾纤中精确定位目标成为本领域的技术难题。目前存在的解决方案如下：
技术1：如图1所示，使用打印/粘贴/绑扎在电缆上的标签，该技术存在标签容易散落、丢失、字迹模糊、逐个翻看标签信息来找到目标端头，由于以上特点导致查找效率低、容易出错等缺陷。
技术2：通过发光二极管点亮线缆组件两端来定位到线缆两端，该技术对缆的类型有限制，必须是有金属加强筋或类似结构能够为二极管提供金属导通回路的结构形式的缆，使得应用范围被限制。
技术3：通过点亮塑料光纤的方式识别光纤跳纤两端，该技术识别方法直观、高效、准确，但由于是石英光纤和塑料光纤配合工作，导致光纤尺寸增加，故导致整个配线系统缆体积增大，从容量上来说，无形增加线缆管理的难度。
技术4：通过一根石英光纤与多根塑料光纤集成到一个光纤跳纤连接器上，石英光纤传递业务，塑料光纤传递识别信息的方式来传递识别信号。
技术5：通过在光纤跳纤连接器上增加电子标签，用电子标签体现和追踪光纤跳纤信息。该标签高效，但目前无法完全克服标签信息录入错误的风险。
综上所述，可知技术1～技术3，均能直观的识别光纤跳纤的两端，但无法实现直观、用目测方式识别两端连接器可靠连接与否；技术4：由于是一根石英光纤和多根玻璃光纤通过多个卡扣进行扣接，光纤跳纤直径物理尺寸增加，降低了配线容量；技术5存在标签信息录入错误的风险。可见，现有的各种光纤跳纤识别技术存在相应的技术弊端，影响识别效率。所以，如何提供一种解决方案，能够在不改变原有缆径以及无需录入标签信息的情况下，实现光纤跳纤的识别，成为目前亟待解决的技术问题。

其中，标识光模块210，如图3所示，具体包括：第一控制器211、第一光发射器212和第一光探测器213；其中：
第一控制器211，设置为向第一光发射器发送控制指令；
第一光发射器212，设置为接收到所述控制指令后，生成标识光，并将标识光输出至光耦合器220；
第一光探测器213，设置为在探测到光耦合器220反馈的标识光后，向第一控制器211发送通知消息；
第一控制器211，还设置为在接收到第一光探测器213发送的通知消息后，输出可靠连接指示信号。
本实施例中，由于标识器主要用于光纤跳纤两端的识别，所以第一光发射器生成的标识光的波长要与光纤跳纤传输的业务光的波长不同。例如，选择850nm VCSEL光发射器。而对于第一光探测器的选择，基于成本和性价比最优选择PIN光电二极管。
本实施例中，标识光模块发射和接收标识光可以共用一个光路，此时，标识光模块内应配备反射滤光片，该反射滤光片可以将第一光发射器212发出的标识光进行透射，将从光耦合器220侧来的标识光反射至第一光探测器213。
本实施例中，光耦合器220可以为：光纤耦合器或波分复用滤波片。其中，光纤耦合器优选为Tap耦合器。
本实施例提供的标识器可以发射标识光，并通过检测是否接收到标识光的方式，判定包含光纤跳纤的光链路是否可靠，为识别光纤跳纤提供了重要支持。

结构形式二：第二光探测器411A和第二光发射器412B，具体如图7所示；
对于上述结构形式一：

本实施例中，光处理器410发射和接收标识光可以共用一个光路，那么，当光处理器410采用结构形式二时，光处理器410内还应配备反射滤光片，该反射滤光片可以将第二光发射器412B发出的标识光进行透射，将发送端发送的标识光反射至第二光探测器411A，具体如图7所示。

当光纤连接器1、目标光纤跳纤和光纤接头识别器组成的光链路为可靠连接时，光纤连接器2替换光纤接头识别器与目标光纤跳纤的端口B相连；光纤连接器1的标识器与光纤连接器2的标识器通过互相握手通讯的方式，对光纤连接器1、目标光纤跳纤和光纤连接器2组成的光链路的连接可靠性进行检测，并将检测结果通过光纤连接器1和光纤连接器2上的指示灯表示。
本实施例中，主控制器在将目标光纤跳纤编码信息写入光纤连接器1的标识器和光纤连接器2的标识器后，优选地，还通过标识器激活光纤连接器1和光纤连接器2上的指示灯，以使指示灯的显示状态表示光纤连接器1和光纤连接器2为待连接状态(如绿光慢闪)。
本实施例中，光纤连接器1利用标识器与光纤接头识别器通过互通标识光的方式，对光纤连接器1、目标光纤跳纤和光纤接头识别器组成的光链路的连接可靠性进行检测，具体包括：
光纤连接器1利用标识器向光纤接头识别器发送标识光；

光纤连接器1和光纤连接器2判断是否接收到对端发送的标识光，若是，则判定光链路连接可靠；否则，判定光链路的连接不可靠。
为了更清楚的说明本发明所述系统的实施过程，下面结合实际应用的场景，给出本发明一个较佳的实施例，并结合对实施例的描述，进一步给出本发明的技术细节，使其能够更好地说明本发明所述系统的具体实现过程。
本发明实施例所述系统实现智能ODN标识的实现过程如下：
步骤1：主控制器向后台发出待施工指令，由后台根据工单系统连接光纤连接器1和光纤连接器2对应的标识器，将目标跳纤的编码信息写入标识器。优选地，后台写入标识器的地址采用闭环握手识别的方式，以确保光纤跳纤编码信息正确。主控制器通过后台向光纤连接器1和光纤连接器2的标识器发出指示灯激活指令，标识器接收到激活指令后，激活对应光纤连接器上的LED指示灯，用LED指示灯状态1(如绿光慢闪)标识光纤连接器1和光纤连接器2处于待施工操作和连接状态。
步骤2：将光纤跳纤(两端接口分别定义为A1和B1)A1端连接到光纤连接器1，B1端连接到光纤接头识别器。
步骤3，光纤连接器1对应的标识器接收到主控制器侧发送的检测指令后，向光纤接头识别器侧发送标识光。
步骤4，光纤接头识别器若接收到光纤连接器1的标识器发送的标识光，则向光纤连接器1的标识器反馈标识光，并控制自身指示灯为绿光常亮状态；若未接收到光纤连接器1的标识器发送的标识光，则光纤接头识别器侧指示灯不点亮，说明光链路不可靠。
产生光链路不可靠的原因有：光纤连接器1与光纤跳纤端口A1的连接不可靠、光纤接头识别器与光纤跳纤端口B1的连接不可靠、光纤连接器1与光纤接头识别器连接的不是同一根光纤跳纤，光纤跳纤故障，光纤接头识别器故障或端口异常等等。
步骤5，光纤连接器1对应的标识器若接收到光纤接头识别器反馈的标识光，则判定为光链路连接可靠，将光纤连接器1上的指示灯由绿光慢闪变为绿光常亮；反之，若未接收到光纤接头识别器反馈的标识光，则说明光链路链接不可靠，此时，光纤连接器1上的指示灯仍为绿光慢闪，需要对不可靠因素做进一步排查。
步骤6：拔下光纤接头识别器，将B1端口可靠连接到光纤连接器2，此时系统架构图如图9所示。
步骤7：光纤连接器1和光纤连接器2通过标识器互相握手通讯，若握手通讯失败，通过各自的指示灯进行表征；若握手通讯成功，表示光纤连接器1与A1端口、光纤连接器2与B1端口均已连接可靠，并且两端来自同一条光纤跳纤，此时，光纤连接器1和光纤连接器2上的指示灯表征为施工正确。在指示灯显示一段时间后，主控制器可以通过标识器主动关闭指示灯；或者，不做任何操作，表征施工正确的指示灯在常亮一定时间后自动关闭。
在通过上述方式进行施工后，质检人员还可以利用标识器对施工后的光链路进行二次检验，二次检验的过程如下：
主控制器发出质检指令，由后台根据工单系统连接光纤连接器1和光纤连接器2对应的标识器，并通过标识器激活对应光纤连接器对应的指示灯，用指示灯状态标识光纤连接器1和光纤连接器2处于待二次检验阶段(因为此时已完成光纤跳纤连接，仅仅为检验连接是否正确并可靠)。光纤连接器1与光纤连接器2通过标识器互相握手通讯。若两端均可靠连接并且接头正确，两端指示灯熄灭，表示连接正确、可靠；若握手通讯失败，指示灯呈现告警状态，例如LED绿光快速闪烁等。
显然，本领域的技术人员可以对本发明进行各种改动和变型而不脱离本发明的精神和范围。这样，倘若本发明的这些修改和变型属于本发明权利要求及其等同技术的范围之内，则本发明也意图包含这些改动和变型在内。
工业实用性
本发明实施例通过标识光对光链路的连接可靠性进行检测，并通过指示灯对可靠性进行直观显示的技术方案，解决了已有的光纤跳纤识别技术需要对光纤缆径进行改变或者需要录入标签信息等影响识别效率的问题，达到了在不改变原有缆径的情况下实施、可以直观目测、高效识别光纤跳纤的两端、避免光纤跳纤两端标签信息错误的风险以及可以识别光纤跳纤两端是否可靠连接的技术效果。
