图 1为本发明实施例一的海缆系统的结构示意图。 下述本发明实施例二
LME应用于图 1所示的海缆系统中。 如图 1所示, 该海缆系统中至少包括: RPT、 OEQ、 BU和光缆等水下设备, 以及 LME、 DCN和 NMS, 该海缆系统 中还可以包括多种岸上设备,每种岸上设备均可与 DCN连接,具体岸上设备 在图 1 中未示出。 RPT、 OEQ、 BU和光缆设置在水下, 多个 RPT、 OEQ和 BU通过光缆连接; LME设置在岸上, 每个水下支路的端点连接一个 LME, 该 LME的另一端连接到 DCN, NMS通过 DCN获取 LME收集的各个水下设 备的信息。
图 2为本发明实施例二的海缆系统水下设备管理方法的流程图。 如图 2 所示, 该方法包括如下过程。
步骤 201 : LME根据 NMS预先配置的水下设备的属性信息, 获取水下 设备的工作状态信息。
步骤 202: LME根据水下设备的工作状态信息和预先配置的水下设备的 属性信息, 模拟产生水下设备的性能信息和告警信息, 并上报 NMS。
在本发明实施例二中, 采用 LME获取水下设备的工作状态信息, LME 根据获取的工作状态信息模拟生成水下设备的性能信息和告警信息上报给
NMS, 从而在 NMS —端能够像接收岸上设备的性能和告警信息那样, 接收 水下设备的性能信息和告警信息, NMS接收的水下设备的性能信息和告警信 息不是水下设备真实发送的性能信息和告警信息,而是由 LME模拟生成的水 下设备的性能信息和告警信息,因此 NMS能够不借助人工辨识即可获知水下 设备的性能信息和告警信息,解决了现有技术中 NMS无法直接获知水下设备 的性能信息和告警信息的技术问题,从而使得 NMS能够像管理岸上设备那样 直接管理水下设备。
图 3为本发明实施例三的海缆系统水下设备管理方法的流程图。 如图 3 所示, 该方法包括如下过程。
首先, LME根据 NMS预先配置的水下设备的属性信息, 获取水下设备 的工作状态信息。 具体地, 在本发明实施例三中, 该过程包括以下步骤 301 至步骤 303。
步骤 301 : NMS向 LME配置需要上报性能信息和告警信息的至少一个 水下设备的属性信息。

步骤 302: LME通过设置在 LME内的 OTDR检测至少一个水下设备, 获取 OTDR曲线。
在本发明实施例三中, 采用 OTDR检测的方法获取水下设备的工作状态 信息,通过 OTDR检测获取 OTDR曲线, 然后根据该 OTDR曲线获取该水下 设备的工作状态信息。 在 LME内包含 OTDR模块, 可以实现 OTDR检测。 OTDR采用光的背向散射与菲涅耳反射的原理。 由于光纤材料密度不均匀、 掺杂成分不均勾以及光纤本身的缺陷, 当光在光纤中传输时, 沿光纤长度上 的每一点均会引起散射, 在连接器、 机械接续、 断裂或光纤终结处, 会发生 反射。 散射光及反射光有一部分可背向传输回到 OTDR, 被探测器接收。 从 所接收的光的强弱变化, 可以判断光纤各个位置的传输特性。 OTDR利用光 在光纤中传播时产生的背向散射光来获取衰减的信息,可用于测量光纤衰减、 接头损耗、 光纤故障点定位以及了解光纤沿长度的损耗分布情况等。
步骤 303: LME根据 OTDR曲线和至少一个水下设备的属性信息, 采用 分析算法进行事件分析, 获取水下设备的工作状态信息。
具体地, 水下设备的工作状态信息可以包括: 光缆的衰减信息、 反射信 息和断纤事件信息, 和 /或, RPT 的入纤光功率信息和出纤光功率信息, 和 / 或, BU的衰减信息、 干路断纤信息和支路断纤信息, 和 /或, OEQ的衰减变 化信息。
在本步骤中, 具体地, LME在根据 OTDR曲线和至少一个水下设备的属 性信息进行事件分析时, 可以采用数字滤波算法、 差分曲线的褶分析算法、 曲线投影面积算法和与基础曲线对比算法中的任意一种或几种的组合进行事 件分析。 上述数字滤波算法、 差分曲线的褶分析算法、 曲线投影面积算法和 与基础曲线对比算法在现有技术中应用于雷达、 航海领域的模式识别中, 在 本发明实施例三中, 将上述方法应用于对 OTDR曲线的分析过程, 从而实现 海缆系统管理。
在一种具体实施方式中, LME根据 OTDR曲线和至少一个水下设备的 属性信息, 采用分析算法进行事件分析, 获取水下设备的工作状态信息的过 程具体方法包括: 首先, 获取 OTDR曲线的上升沿和下降沿。 然后, 根据上 升沿和下降沿的位置关系或上升沿的底端或顶端的光功率信息, 获取水下设 备的工作状态信息。 其中, 水下设备具体可以包括以下设备中的一种或几种 的组合: 光缆、 中继器、 分支器和光平衡设备。 相应地, 水下设备的工作状 态信息可以包括以下信息的一种或几种的组合: 光缆的衰减信息、 反射信息 和断纤事件信息, 和 /或, RPT的入纤光功率信息和出纤光功率信息, 和 /或, BU的衰减信息、 干路断纤信息和支路断纤信息, 和 /或, OEQ的衰减变化信 息。 相应地, 上述^^据上升沿和下降沿的位置关系或上升沿的底端或顶端的 光功率信息, 获取水下设备的工作状态信息的过程具体包括: 首先, 根据上 升沿和下降沿的位置关系, 获取衰减信息、 反射信息和断纤信息, 并且, 根 据上升沿的底端获取入纤光功率信息, ^^据上升沿的顶端获取出纤光功率信 息。 然后, 结合水下设备的属性信息中的水下设备的标识、 该水下设备所属 跨度、 该水下设备与前一个 RPT的距离等信息, 确定上述衰减信息、 反射信 息、 断纤信息、 入纤光功率信息和出纤光功率信息对应的水下设备。 其中, 在获取 OTDR曲线的上升沿和下降沿时,可以根据 OTDR曲线的数据获得差 分曲线, 然后进行差分曲线的褶分析计算, 获得 OTDR曲线的上升沿和下降 沿。 差分曲线的褶分析计算过程如下。 第一步, 依次寻找差分曲线相邻的特 征点, 特征点包括: 极大值点和极小值点。 第二步, 判断每个极小值点是否 为一个清晰的谷点, 如果是, 标注是左侧清晰或右侧清晰。 第三步, 判断每 个极大值点是否为一个清晰的峰点, 如果是, 标注是左侧清晰或右侧清晰。 第四步,根据全部清晰的峰点和全部清晰的谷点的位置判断上升沿和下降沿。
步骤 304: ME根据水下设备的工作状态信息和预先配置的水下设备的属 性信息, 模拟产生水下设备的性能信息和告警信息, 并上报 NMS。
在本步骤中, 具体地, LME根据至少一个水下设备的属性信息以及光缆 的衰减信息、 反射信息和断纤事件信息、 RPT的入纤光功率信息和出纤光功 率信息、 BU的衰减信息、 干路断纤信息和支路断纤信息, OEQ的衰减变化 信息, 按照预设标准分别生成光缆、 RPT、 BU、 OEQ的性能信息和告警信息 并上 "¾ NMS。
在本步骤中, 上述预设标准根据 DCN与 NMS适用的通信标准设置。 较 佳地, 上述预设标准可以采用国际电信联盟 ( International Telecommunication Union - Telecommunication, 简称 ITUT )标准, 具体可以采用 ITUT标注中的 G.7710, G.784、 G.774、 G.783、 G.801、 G821、 G.827、 G.827.1、 M.2101、 M.2101.1、 M.2110、 M.2120、 G.806、 G.7710, M、 2140、 M.3100 等标准。 或者, 上述预设标准还可以采用中国国标 YD1289.1、 YD1289.2、 YD1289.3 等标准。 LME根据对 OTDR曲线的分析结果, 按照上述标准中的规定, 计算 生成光缆、 RPT、 BU、 OEQ的性能信息和告警信息, 上述性能信息和告警信 息为 LME模拟的性能信息和告警信息。 然后, LME将上述模拟的性能信息 和告警信息上报给 NMS。
在本发明实施例三中, LME采用 OTDR检测水下设备, 获取 OTDR曲 线, 对该 OTDR曲线进行事件分析, 获取各个水下设备的工作状态信息, 然 后 LME根据获取的工作状态信息,按照预设的通信标准模拟生成各个水下设 备的性能信息和告警信息, 将符合该通信标准的性能信息和告警信息上报给 NMS, 从而在 NMS —端能够像接收岸上设备的性能和告警信息那样, 接收 水下设备的性能信息和告警信息, NMS接收的水下设备的性能信息和告警信 息不是水下设备真实发送的性能信息和告警信息,而是由 LME模拟生成的水 下设备的性能信息和告警信息,因此 NMS能够不借助人工辨识即可获知水下 设备的性能信息和告警信息,解决了现有技术中 NMS无法直接获知水下设备 的性能信息和告警信息的技术问题,从而使得 NMS能够像管理岸上设备那样 直接管理水下设备。 并且, 由于 OTDR能够检测到光纤的断纤故障, 因此采 用本发明实施例三的方法, 不仅能够对水下的 RPT、 BU、 OEQ等设备进行 监控和管理, 并且还能够对连接上述设备的光缆进行监控和管理, 进一步扩 大了水下设备管理方法的应用范围, 增大了故障判断和定位的准确性。
图 4为本发明实施例四的海缆系统水下设备管理方法的流程图。 如图 4 所示, 该方法包括如下过程。
首先, LME根据 NMS预先配置的水下设备的属性信息, 获取水下设备 的工作状态信息。 具体地, 在本发明实施例四中, 该过程包括以下步骤 401 和步骤 402。
步骤 401 : NMS向 LME配置需要上报性能信息和告警信息的至少一个 水下设备的属性信息。
在本步骤中, 水下设备包括: RPT、 BU、 OEQ。 每个水下设备的属性信 息包括: 该水下设备的标识。 具体地, 在水下, 每一个 RPT、 每一个 BU、 和每一个 OEQ均被分配——对应的网元标识,每个标识在整个光缆系统网络 中均是唯一的, 用于唯一标识对应的某一个水下设备。
步骤 402: LME根据 NMS配置的水下设备的属性信息, 获取水下设备 周期性地上报的性能数据包。
在本步骤中, 每个性能数据包包括: 水下设备的标识和工作状态信息。 具体地, 步骤 402可以包括如下第一步和第二步。
第一步, RPT、 BU和 OEQ向全部 LME周期性地广播自身的性能数据包。 目前, 由于水下设备要求的可靠性很高, 要求 25年免维修, 因此, 为水 下设备设计的功能尽量简单。 目前的水下设备可以通过读寄存器的操作收集 状态信息, 然后将收集的状态信息打包发送。 而产生告警信息和性能信息需 要进行大量的信息处理工作, 如果在水下设备实现大量信息处理功能, 会导 致水下设备的可靠性无法满足要求。 并且, 由于水下设备与岸上设备的通讯 条件很差, 一般使用调顶方式通讯, 在通讯时要考虑信号的质量, 由于带宽 很低, 无法满足 NMS管理报文传输的要求。基于上述两个原因, 水下设备可 以上报自身的状态信息, 而无法直接上报性能信息和告警信息。 在本发明实 施例四中, 采用水下设备向 LME上报工作状态信息的方法, 使 LME获取各 个水下设备的工作状态信息。
在本步骤中, 海缆系统中位于水下的 RPT、 BU和 OEQ向 LME周期性 地广播各自自身的性能数据包。 每个性能数据包包括: 该水下设备的标识和 工作状态信息。具体地,每个 RPT发送的性能数据包包括该 RPT的标识和工 作状态信息; 每个 BU发送的性能数据包包括该 BU的标识和工作状态信息; 每个 OEQ发送的性能数据包包括该 OEQ的标识和工作状态信息。 具体地, 水下设备的工作状态信息可以包括该水下设备当前的入功率、 出功率、 增益、 衰减等性能。
第二步, LME根据配置的需要上报性能信息和告警信息的至少一个水下 设备的属性信息, 获取需要上报性能信息和告警信息的 RPT、 BU和 OEQ周 期性上报的性能数据包。
在步骤 401中, LME根据配置已经获知自身管辖的需要上报性能信息和 告警信息的水下设备,在步骤 402中, 一个 LME首先会接收到位于水下的水 下设备上报的各自的性能数据包, 则该 LME根据步骤 401中的配置,从接收 的性能数据包中选出属于步骤 401 中配置的需要上报性能信息和告警信息的 水下设备发送的性能数据包, 然后丟弃其余的性能数据包。
在步骤 402之后, 执行步骤 403。
步骤 403: LME根据水下设备的工作状态信息模拟水下设备的性能信息 和告警信息, 并上报 NMS。
在本步骤中, 具体地, LME根据需要上报性能信息和告警信息的 RPT、 BU和 OEQ周期性上报的性能数据包, 按照预设标准分别生成需要上报性能 信息和告警信息的 RPT、 BU和 OEQ的性能信息和告警信息并上报 NMS。
在本步骤中, 上述预设标准根据 DNC与 NMS适用的通信标准设置。 较 佳地, 上述预设标准可以采用国际电信联盟 ( International Telecommunication Union - Telecommunication, 简称 ITUT )标准, 具体可以采用 ITUT标注中的 G.7710, G.784、 G.774、 G.783、 G.801、 G821、 G.827、 G.827.1、 M.2101、 M.2101.1、 M.2110、 M.2120、 G.806、 G.7710, M、 2140、 M.3100 等标准。 或者, 上述预设标准还可以采用中国国标 YD1289.1、 YD1289.2、 YD1289.3 等标准。 LME根据配置中指示的水下设备上报的性能数据包中各个水下设备 的性能数据, 按照上述标准中的规定, 计算生成 RPT、 BU、 OEQ 的性能信 息和告警信息, 上述性能信息和告警信息为 LME模拟的性能信息和告警信 息。 然后, LME将上述模拟的性能信息和告警信息通过 DNC上报给 NMS。
在本发明实施例四中, 采用水下设备向 LME 上报性能数据包的方式使 LME获取各个水下设备的工作状态信息, 然后 LME根据获取的水下设备的 工作状态信息, 按照预设的通信标准模拟生成各个水下设备的性能信息和告 警信息,将符合该通信标准的性能信息和告警信息上报给 NMS,从而在 NMS 一端能够像接收岸上设备的性能和告警信息那样, 接收水下设备的性能信息 和告警信息, NMS接收的水下设备的性能信息和告警信息不是水下设备真实 发送的性能信息和告警信息,而是由 LME模拟生成的水下设备的性能信息和 告警信息,因此 NMS能够不借助人工辨识即可获知水下设备的性能信息和告 警信息,解决了现有技术中 NMS无法直接获知水下设备的性能信息和告警信 息的技术问题, 从而使得 NMS能够像管理岸上设备那样直接管理水下设备。
