Description

一种检测光纤故障点的方法和装置 技术领域
本申请涉及但不限于无源光网络(PON，Passive Optical Network)技术。
背景技术
PON是一种应用于接入网，局端设备如光线路终端(OLT，Optical Line Terminal)与多个用户端设备如光网络单元(ONU，Optical Network Unit)之间通过无源的光缆、光分/合路器(Splitter)等组成的光分配网(ODN，Optical Distribution Network)。
在PON中，将OLT与Splitter之间的光纤称为主干光纤，简称主干；将Splitter与用户端设备之间的光纤称为分支光纤，简称分支。通常，OLT包括一个或一个主干，每个主干通过Splitter经由一个或一个以上分支连接到用户端设备。主干连接在OLT的PON接口与Splitter的光纤接口之间。不难理解，一个PON接口经由主干和Splitter连接一个或一个以上用户端设备。
随着PON的网络规模的增大，用户数量增多，网络维护越来越复杂。可以利用光时域反射器(OTDR，Optical Time Domain Reflectometer)测量OLT的PON接口至其上每个用户端设备之间的光纤的故障点即断点、衰减故障点、或异常故障故障点，也可以通过OLT检测一个PON接口上哪些用户端设备与OLT通信中断，下文中，将通信中断的用户端设备称为掉线用户端设备。通过OTDR检测出的故障点位于主干或者分支，为了描述方便，通常将位于主干的故障点称为主干故障点，将位于分支的故障点称为分支故障点。故障点通常通过其与OLT之间的距离来表示，例如故障点1，位置为10.1km，说明该故障点位于距离OLT 10.1km处。
通常维护人员需要确定故障点与掉线用户端设备之间的一一对应关系，下文中，将上述一一对应关系称为故障对应关系。为了描述方便，将其中的故障点未被解决即断点、衰减故障点、或异常故障故障点未被修复的故障对应关系称为待处理对应关系，而将其中的故障点已被解决的故障对应关系称 为已处理对应关系。
需要说明的是，通常通过网管系统获取上述OTDR测试结果和OLT检测结果。其中，接收到用于指示OLT的哪个PON接口上存在掉线用户端设备的告警信息后，网管系统提取告警信息指示的PON接口，并指示OTDR针对提取出的PON接口进行故障点测试；OTDR完成故障点测试后，将OTDR测试结果返回给网管系统；接收到掉线告警并提取出PON接口后，网管系统还获取针对提取出的PON接口的OLT检测结果。如果OTDR测试结果包含主干故障点，显示主干故障点；如果OTDR测试结果包含一个分支故障点，且OLT检测结果包含一个或一个以上掉线用户端设备，则显示上述一个分支故障点与每个掉线用户端设备分别组成的每个待处理对应关系；如果OTDR测试结果包含两个或两个以上分支故障点，此时OLT检测结果相应地包含两个或两个以上掉线用户端设备，显示上述每个分支故障点和每个掉线用户端设备，显然此情况下，无法确定显示出的每个分支故障点和每个掉线用户端设备之间的待处理对应关系。不难看出，掉线用户端设备的数量大于或等于分支故障点数量，例如，当存在两个距离OLT长度相同的分支故障点时，在OTDR测试结果中，只包括一个分支故障点，该分支故障点代表上述两个分支故障点。
当检测出两个或两个以上分支故障点时，维护人员需要确定待处理对应关系。当检测出2个故障点时，可选范围至少包括4个对应关系，此时，维护人员需要从至少4个对应关系中选择其中2个作为待处理对应关系，当检测出3个故障点时，可选范围至少包括9个对应关系，此时，维护人员需要从至少9个待处理对应关系中选择其中3个作为待处理对应关系。显然，随着故障点数量的增加，待处理对应关系的可选范围随之增大。
相关技术中，为了确定待处理对应关系，需要在PON中增加辅助测试设备，这样使得网络拓扑更加复杂，增加了网络维护的复杂度，也增加了组网成本。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求 的保护范围。

附图概述

图3(b)为PON网络出现分支故障的第二示意图。
本发明的实施方式
下文中将结合附图对本发明的实施方式进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图1为本发明实施例检测光纤故障点的方法的流程图，如图1所示，包括：
步骤101：当OTDR检测出一个或一个以上分支故障点时，针对获得的每个掉线用户端设备，在保存有待处理对应关系的数据库中查找包含有掉线用户端设备的待处理对应关系。
步骤101之前还包括：获取每个掉线用户端设备。
步骤102：从检测出的分支故障点和获得的掉线用户端设备中删除查找到的待处理对应关系中的分支故障点和掉线用户端设备。
通过步骤102，得到更新后的分支故障点和掉线用户端设备。
如果步骤101中没有查找到待处理对应关系，更新前的分支故障点和掉 线用户端设备即步骤101中的分支故障点和掉线用户端设备与更新后的分支故障点和掉线用户端设备相同。在查找出的待处理对应关系中，可能存在包括相同的分支故障点的两个或两个以上待处理对应关系，此时，上述相同的分支故障点只需在更新前的分支故障点和掉线用户端设备中删除一次。
通过步骤102，更新后的分支故障点和掉线用户端设备之间包含的对应关系的可选范围，等于或者小于更新前的分支故障点和掉线用户端设备之间包含的对应关系的可选范围。也就是说，由于分支同时中断的可能性非常小，因此前者的可选范围小于后者的可选范围的可能性非常大，因此通过本发明实施例方法，以较大的可能性缩小了对应关系的可选范围，减小了维护人员确定待处理对应关系的工作量，从而降低了PON网络维护的复杂度。
为了使本发明实施例方法更加完善，本发明实施例方法之后还包括：如果更新后的分支故障点和掉线用户端设备中包括一个分支故障点和一个或一个以上用户端设备，则将上述一个分支故障点分别与上述每个掉线用户端设备确定为待处理对应关系，并保存确定出的待处理对应关系到数据库。
可选地，
该方法还包括：如果确定出待处理对应关系，显示查找到的待处理对应关系和确定出的待处理对应关系。此情况下，维护人员可以直接获得待处理对应关系，明显提高了维护效率。
可选地，
如果未确定出待处理对应关系，即更新后的分支故障点和掉线用户端设备中包括两个或两个以上分支故障点，方法还包括：显示查找到的待处理对应关系、以及更新后的每个分支故障点和每个掉线用户端设备。当查找到待处理对应关系时，根据显示出的信息，维护人员只需从更新后的分支故障点和掉线用户端设备之间包含的对应关系中确定待处理对应关系，缩小了维护人员确定待处理对应关系的工作量，较好地提高了维护效率。
为了使本发明实施例方法更加完善，本发明实施例方法还包括：接收到用于指示已处理对应关系的指示信息如告警恢复信息后，在数据库中，查找与接收到的已处理对应关系相同的待处理对应关系，并删除查找到的待处理 对应关系。
通过上述在数据中增加以及删除待处理对应关系的步骤，本发明实施例方法保证了数据库中保存有待处理对应关系。这样，实现了结合OTDR测试结果、OLT检测结果和数据库中保存的信息，缩小更新前的分支故障点和掉线用户端设备之间包含的对应关系的可选范围。
本发明实施例还提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令用于执行上述检测光纤故障点的方法。
图2为本发明实施例检测光纤故障点的装置的组成结构示意图，该装置设置在实现网管系统的设备上。如图2所示，包括查找单元21和处理单元22，其中，
查找单元21，设置为：当OTDR检测出一个或一个以上分支故障点时，针对获得的每个掉线用户端设备，在保存有待处理对应关系的数据库中查找包含有掉线用户端设备的待处理对应关系；
处理单元22，设置为：从检测出的分支故障点和获得的掉线用户端设备中删除查找单元查找到的待处理对应关系中的分支故障点和掉线用户端设备。
查找单元21还设置为：获取每个掉线用户端设备。

下面举例说明本发明的实施方式。
如图3(a)所示，用户端设备ONU1对应的分支上出现分支故障1，通过本发明实施例方法，显示分支故障点1与用户端设备1之间的待处理对应关系，并将该待处理对应关系保存到数据库中。在图3(a)所示的故障点的基础上，如图3(b)所示，进一步出现与用户端设备ONU2对应的分支故障点2，此时，OTDR测试结果显示分支故障点1和分支故障点2，OLT检测结果显示用户端设备1和用户端设备2掉线，通过本发明实施例方法步骤101查询到分支故障点1与用户端设备1之间的待处理对应关系1，通过本发明实施例方法步骤102及其后续步骤得到分支故障点2与用户端设备2之间的待处理对应关系2，显示待处理对应关系1和待处理对应关系2，并将待处理对应关系2保存到数据库。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。

虽然本发明所揭露的实施方式如上所述，但所述的内容仅为便于理解本发明而采用的实施方式，并非用以限定本发明。任何本发明所属领域内的技术人员，在不脱离本发明所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本发明的专利保护范围，仍须以所附的权利要求书所界定的范围为准。
工业实用性
通过本发明实施例，实现了在不增加辅助测试设备的情况下，结合OTDR测试结果即检测出的每个分支故障点、OLT检测结果即获得的每个掉线用户端设备、和查找到的数据库中的信息，获得更新后的分支故障点和掉线用户端设备，从而较好地缩小了待处理对应关系的可选范围，降低了维护工作量和网络维护的复杂度。
