具体实施方式
下面通过附图和实施例， 对本发明的技术方案做进一步的详细描述。
图 1为本发明一个实施例提供的跳纤连接状态的信号产生方法流程图， 如 图 1所示， 该方法包括：
5101、 生成与第一端口对应的光信号；
5102、通过第一光纤将光信号发送至第二端口，第一光纤连接跳纤的两端， 跳纤的两端分别连接第一端口和第二端口。
具体的， 第一端口和第二端口为 FTTX运营商机房的 0DF上连接的任意两个 端口， 第一端口和第二端口之间通过两端分别带插头的跳纤连接，检测第一端 口和第二端口之间的连接情况即为检测跳纤两端的插头与第一端口和第二端 口的连接情况。可以在跳纤上增加传递检测信号的第一光纤，该第一光纤可以 为 （Plas t ic Opt ica l Fiber; 以下简称： P0F ), 当然也可以为其他类型大数 值孔径的光纤以利于光耦合， 例如光晶体或聚合物等， 还可以为聚氯乙烯 ( Polyvinylchlor ide; 以下筒称： PVC )光纤等特种光纤。 第一光纤的长度可 以才艮据跳纤的长度设置，其位置与跳纤平行放置， 第一光纤的两端分别固定在 跳纤的两端插头上。这样，从第一端口经由第一光纤发送至第二端口的光信号， 若可以被第二端口接收， 则可以认为第一端口与第二端口处于连接状态。若第 二端口没有接收到第一端口经由第一光纤发送至第二端口的光信号，则说明第 一端口与第二端口之间处于断开状态。其中， 由于选用第一光纤作为传递检测 信号的路径， 则检测信号为光信号。与第一端口对应的光信号可以根据一定的 规则生成， 该信号用以使第一端口区别于其他端口， 第二端口若接收到该光信 号后， 可以根据光信号的生成规则检测到目前与第二端口连接的是哪一个端 口。
本发明实施例提供的跳纤连接状态的检测方法， 在连接任意两个端口的跳 纤上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信 号并通过光纤发送至另一个端口 ,可以通过对另一个端口处接收光信号的情况 检测这两个端口的连接状态。 不同跳纤的光路相互独立，检测过程不会出现光 路间的干扰信号， 并且使检测过程更加安全。
图 2为本发明另一个实施例提供的跳纤连接状态的信号产生方法流程图 , 如图 2所示， 该方法包括：
5201、 生成第一端口的标识电信号；
5202、 将标识电信号转换成光信号；
S203、通过第一光纤将光信号发送至第二端口，第一光纤连接跳纤的两端， 跳纤的两端分别连接第一端口和第二端口。
在上一实施例的基 上， 由于电信号的生成较为容易， 可以通过逻辑器件 为每个端口生成区别于其他端口的标识（ ident if icat ion; 以下简称： ID )电 信号， 再通过一些光电转换器件， 例如发光二极管 （Light Emi t t ing Diode; 以下筒称： LED )等将 ID电信号转换成光信号。 从第一端口经由第一光纤发送 至第二端口的光信号， 若可以被第二端口接收， 则可以认为第一端口与第二端 口处于连接状态 ,并且可以根据光信号的生成规则检测目前与第二端口连接的 是哪一个端口。若第二端口没有接收到第一端口经由第一光纤发送至第二端口 的光信号 , 则说明第一端口与第二端口之间处于断开状态。
本发明实施例提供的跳纤连接状态的检测方法， 在连接任意两个端口的跳 纤上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信 号并通过光纤发送至另一个端口，可以通过对另一个端口处接收光信号的情况 检测这两个端口的连接状态。 不同跳纤的光路相互独立，检测过程不会出现光 路间的千扰信号， 并且使检测过程更加安全。
图 3为本发明一个实施例提供的跳纤连接状态检测方法流程图 , 如图 3所 示， 该方法包括：
S301、 根据是否接收到第一端口通过第一光纤发送至第二端口的光信号判 断第二端口与第一端口的连接状态第一光纤连接跳纤的两端，跳纤的两端分别 连接第一端口和第二端口；
S302、 若接收到光信号， 则根据光信号获取第一端口对应的端口标识。 具体的， 第一端口和第二端口为 FTTX运营商机房的 0DF上连接的任意两个 端口， 第一端口和第二端口之间通过两端分别带插头的跳纤连接， 为了测试跳 纤两端的插头与第一端口和第二端口的连接情况，可以在跳纤上增加传递检测 信号的第一光纤， 该第一光纤可以为 P0F, 当然也可以为其他类型大数值孔径 的光纤。 第一光纤的长度可以根据跳纤的长度设置， 其位置与跳纤平行放置， 第一光纤的两端分别固定在跳纤的两端插头上。第一端口经由第一光纤将与第 一端口对应的光信号发送至第二端口， 若第二端口能够接收到该光信号， 则第 一端口与第二端口处于连接状态 ,由于该光信号为第一端口区别于其他端口的 光信号， 因此， 可以根据光信号的生成规则识别出第一端口的端口标识， 即可 以得知目前与第二端口连接的是哪一个端口。
本发明实施例提供的跳纤连接状态检测方法， 在连接任意两个端口的跳纤 上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信号 并通过光纤发送至另一个端口，通过另一个端口处接收光信号的情况检测发送 光信号的端口标识以及这两个端口的连接状态。 不同跳纤的光路相互独立，检 测过程不会出现光路间的千扰信号， 并且使检测过程更加安全。
图 4为本发明另一个实施例提供的跳纤连接状态检测方法流程图 , 如图 4所 示， 该方法包括：
S401、 根据是否接收到第一端口通过第一光纤发送至第二端口的光信号判 断第二端口与第一端口的连接状态， 第一光纤连接跳纤的两端，跳纤的两端分 别连接第一端口和第二端口； 5402、 若接收到光信号， 则将光信号转换成电信号；
5403、 对电信号的频率进行检测， 并才艮据频率识别第一端口对应的端口标 识及第二端口与第一端口的连接质量；
S404、 对第一端口对应的端口标识及第二端口与第一端口的连接状态进行 记录；
S405、 根据第二端口与第一端口的连接状态和 /或连接质量产生报警信号。 在上一实施例的基础上， 可以通过逻辑器件为第一端口生成区别于其他端 口的 ID电信号。 然后通过一些光电转换器件， 例如 LED等将 ID电信号转换成光 信号。若第二端口可以接收到第一端口发送的光信号， 则说明第二端口与第一 端口处于连接状态； 若第二端口无法接收到第一端口发送的光信号， 则第二端 口与第一端口处于断开状态。进一步的， 当第二端口接收到第一端口经由第一 光纤发送的光信号以后， 首先将接收到的光信号转换成电信号。 具体的， 由于 转换后得到的电信号很微弱， 无法直接对其进行检测。 因此， 可以根据脉冲编 码调制原理，将弱的电信号转换成相应的脉冲信号。再对该脉冲信号进行检测， 具体检测可分为两步： 首先判别对端发送的信号是 0还是 1。若对端发送的信号 是 0, 则不输出脉冲。 若对端发送的信号是 1 , 则输出对应的脉冲个数。 将输出 的脉冲个数与检测门限对比， 可判别出对端输出 1 , 同时根据脉冲数可识别连 接的质量， 即脉冲个数多的， 相应连接质量较好。 然后检测对端发送的 ID电信 号对应的端口号。根据检测窗内检测的 0和 1的个数和位置，识别出发送端的端 口标识， 即端口号， 从而可以判别出被连接的两个端口。 并且依据检测出的脉 冲数得出跳纤连接第一端口与第二端口的质量。由于 0DF中连接有大量的跳纤， 而对跳纤进行插拔或更换连接端口的操作以后可能没有及时记录，因此可以对 每个端口进行实时检测， 进而实时监控出与每个端口所连接端口的变化情况， 在检测之后可以记录对端口目前连接的端口对应的端口标识进行记录或更新， 同时记录端口之间连接的状态以及连接的质量情况。若出现端口连接松动或脱 落等情况可以及时发出报警信息， 提示管理人员及时进行相应处理。
本发明实施例提供的跳纤连接状态检测方法， 在连接任意两个端口的跳纤 上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信号 并通过光纤发送至另一个端口，通过另一个端口处接收光信号的情况检测发送 光信号的端口标识以及这两个端口的连接状态。 不同跳纤的光路互相独立，检 测过程不会出现光路间的千扰信号， 并且使检测过程更加安全。 同时， 能够对 每个端口的连接状态进行实时的更新， 方便对端口的错误操作进行相应处理。
本领域普通技术人员可以理解： 实现上述方法实施例的全部或部分步驟可 以通过程序指令相关的硬件来完成，前述的程序可以存储于一计算机可读取存 储介质中， 该程序在执行时， 执行包括上述方法实施例的步骤； 而前述的存储 介质包括： R0M、 RAM, 磁碟或者光盘等各种可以存储程序代码的介质。
图 5为本发明一个实施例提供的跳纤连接状态的信号产生装置结构示意 图， 如图 5所示， 该装置包括： 生成模块 51和发送模块 52; 其中， 生成模块 51 用于生成与第一端口对应的光信号；发送模块 52用于通过第一光纤将光信号发 送至第二端口， 第一光纤连接跳纤的两端，跳纤的两端分别连接第一端口和第 二端口。
具体的 , 第一端口和第二端口为 FTTX运营商机房的 0DF上的任意两个端口， 第一端口和第二端口之间通过两端分别带插头的跳纤连接，为了测试跳纤两端 的插头与第一端口和第二端口的连接情况，可以在跳纤上增加传递检测信号的 第一光纤， 该第一光纤可以为 P0F, 当然也可以为其他类型大数值孔径的光纤。 第一光纤的长度可以根据跳纤的长度设置， 其位置与跳纤平行放置， 第一光纤 的两端分别固定在跳纤的两端插头上。该装置与第一端口之间也通过与第一光 纤相同材质的光纤连接， 例如 P0F。 值得注意的是， 该装置与第一端口之间的 光纤与第一光纤的截面需要对准放置， 这样可以确保该装置中的发送模块 52 发送的光信号能够顺利进入第一光纤。 另外， 为了保证发送模块 52发送的光信 号能够最大限度地进入第一光纤，减少光信号发送过程中的损耗， 该装置与第 一端口之间的截面以及第一光纤的截面要平整，若截面不平整会影响第二端口 接收到的光信号的质量，从而影响对第一端口和第二端口连接状态的判断。 首 先， 生成模块 51生成与第一端口对应的光信号， 该光信号通过发送模块 52经由 第一光纤发送至第二端口， 若该信号可以被第二端口接收， 则第一端口与第二 端口处于连接状态。若第二端口没有接收到第一端口经由第一光纤发送至第二 端口的光信号， 则说明第一端口与第二端口之间处于断开状态。 其中， 与第一 端口对应的光信号可以根据一定的规则生成，即可以为第一端口生成用于区别 于其他端口的光信号， 第二端口若接收到第一端口发送的光信号， 可以根据光 信号的生成规则判断目前与第二端口连接的是哪一个端口。 本发明实施例提供的跳纤连接状态检测装置， 在连接任意两个端口的跳纤 上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信号 并通过光纤发送至另一个端口，通过另一个端口处接收光信号的情况检测发送 光信号的端口标识以及这两个端口的连接状态。 不同跳纤的光路相互独立 ,检 测过程不会出现光路间的千扰信号， 并且使检测过程更加安全。
图 6为本发明另一个实施例提供的跳纤连接状态的信号产生装置结构示意 图， 如图 6所示， 该装置包括： 生成模块 51和发送模块 52; 生成模块 51还可以 包括： 获取单元 511和转换单元 512; 获取单元 51 1用于获取与第一端口对应的 标识电信号； 转换单元 512用于将标识电信号转换成光信号。
在上一实施例的基础上， 可以首先通过获取单元 511为每个端口生成区别 于其他端口的 ID电信号，再通过转换单元 512将 ID电信号转换成光信号。其中， 获取单元 511可以为一些逻辑器件，转换单元 512可以为光电转换器件，例如 LED 等。 可以根据第一光纤和转换单元 512的光特性来选择光信号的波长。 以第一 光纤为 P0F、 转换单元 512为 LED为例， 可以选用波长为 650謹的光作为光信号， 并采用获取单元 511的一个 10管脚输出的方波直接驱动中心波长为 650謹的 LED, 该方波的频率小于 LED的截止频率， 该频率一般可以为几千赫。 发送模块 52将光信号经由第一光纤发送至第二端口， 若可以被第二端口接收， 则可以认 为第一端口与第二端口处于连接状态，并且可以根据光信号的生成规则检测目 前与第二端口连接的是哪一个端口。若第二端口没有接收到第一端口经由第一 光纤发送至第二端口的光信号， 则说明第一端口与第二端口之间处于断开状 态。
本发明实施例提供的跳纤连接状态检测装置， 在连接任意两个端口的跳纤 上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信号 并通过光纤发送至另一个端口 ,通过另一个端口处接收光信号的情况检测发送 光信号的端口标识以及这两个端口的连接状态。 不同跳纤的光路相互独立，检 测过程不会出现光路间的千扰信号 , 并且使检测过程更加安全。
图 7为本发明又一个实施例提供的跳纤连接状态检测装置结构示意图， 如 图 7所示， 该装置包括： 接收模块 61、 判断模块 62、 第一获取模块 63和第二获 取模块 64; 其中，接收模块 61用于接收第一端口通过第一光纤发送至第二端口 的光信号， 第一光纤连接跳纤的两端，跳纤的两端分别连接第一端口和第二端 口； 判断模块 62用于判断接收模块 61是否接收到光信号； 第一获取模块 63用于 根据判断模块 62的判断结果获取第二端口与第一端口的连接状态；第二获取模 块 64用于若接收模块 61接收到光信号，则根据光信号获取第一端口对应的端口 标识。
具体的， 第一端口和第二端口为 FTTX运营商机房的 0DF上连接的任意两个 端口， 第一端口和第二端口之间通过两端分别带插头的跳纤连接， 为了测试跳 纤两端的插头与第一端口和第二端口的连接情况，可以在跳纤上增加传递检测 信号的第一光纤， 该第一光纤可以为 P0F, 当然也可以为其他类型的大数值孔 径的光纤。第一光纤的长度可以根据跳纤的长度设置，其位置与跳纤平行放置， 第一光纤的两端分别固定在跳纤的两端插头上。该装置与第二端口之间的通过 与第一光纤相同材质的光纤连接， 例如 P0F。 该装置与第二端口之间的光纤与 第一光纤的截面需要对准放置 ,这样可以确保该装置中的接收模块 61能够通过 第一光纤顺利接收到光信号。 另外， 为了减少光信号在接收过程中的损耗， 该 装置与第二端口之间的截面以及第一光纤的截面要平整，若截面不平整会影响 第二端口接收到的光信号的质量，从而影响对第一端口和第二端口连接状态的 判断。 第一端口经由第一光纤将与第一端口对应的光信号发送至第二端口， 若 判断模块 62判断出接收模块 61接收到该光信号 ,则第一获取模块 63可以获取到 第一端口与第二端口处于连接状态；若判断模块 62判断出接收模块 61无法接收 到该光信号， 则第一获取模块 63可以获取到第一端口与第二端口处于断开状 态。 另外， 若接收模块 61能够接收到该光信号， 由于该光信号为第一端口区别 于其他端口的光信号， 因此， 第二获取模块 64可以根据光信号的生成规则识别 出第一端口的端口标识， 即端口号， 进而可以得知目前与第二端口连接的是哪 一个端口。
本发明实施例提供的跳纤连接状态检测装置， 在连接任意两个端口的跳纤 上平行设置光纤，使光纤分别与跳纤两端连接，在其中一个端口处产生光信号 并通过光纤发送至另一个端口，通过另一个端口处接收光信号的情况检测发送 光信号的端口标识以及这两个端口的连接状态。 不同跳纤的光路相互独立，检 测过程不会出现光路间的千扰信号， 并且使检测过程更加安全。
图 8为本发明再一个实施例提供的跳纤连接状态检测装置结构示意图， 如 图 8所示， 该装置包括： 接收模块 61、 判断模块 62、 第一获取模块 63和第二获 取模块 64; 进一步的， 该装置还可以包括： 记录模块 65、 第三获取模块 66和报 警模块 67;记录模块 65用于对第一获取模块 63获取到的第一端口的端口标识进 行记录， 若接收模块 61接收到光信号， 则对第二获取模块 64获取到的第一端口 对应的端口标识进行记录； 第二获取模块 64可以包括光电转换单元 641、 检测 单元 642和识别单元 643; 光电转换单元 641用于将光信号转换成电信号； 检测 单元 642用于对电信号的频率进行检测；识别单元 643用于 ^据频率识别第一端 口对应的端口标识； 第三获取模块 66 , 用于根据检测单元 642检测出的频率识 别第二端口与第一端口的连接质量；报警模块 67用于根据第一获取模块 63获取 到的第二端口与第一端口的连接状态和 /或第三获取模块 66获取到的第二端口 与第一端口的连接质量产生报警信号。
在上一实施例的基础上， 由于可以通过逻辑器件为第一端口生成区别于其 他端口的 ID电信号。 然后通过一些光电转换器件， 例如 LED等将 ID电信号转换 成光信号。若判断模块 62判断出接收模块 61接收到该光信号， 则第一获取模块 63可以获取到第二端口与第一端口处于连接状态；若判断模块 62判断出接收模 块 61无法接收到第一端口发送的光信号 ,则第一获取模块 63可以获取到第二端 口与第一端口处于断开状态。进一步的， 当接收模块 61接收到第一端口经由第 一光纤发送的光信号以后， 首先通过光电转换单元 641将接收到的光信号转换 成电信号，再通过检测单元 642检测和识别单元 643识别发送光信号的端口对应 的端口标识以及第二端口与第一端口之间的连接质量。其中， 根据 P0F的光特 性和 PD的光特性可以选用波长为 65 Onm的光作为光信号。 接收模块 61接收到的 光信号经过光电转换单元 641的转换后， 其电压只有 2百亳伏左右。这样微弱的 电信号检测， 通常可以先对其进行信号放大， 再采用模数转换器件进行转换。 但此检测方案成本高。 另一种可行的方法是采用脉冲编码调制的原理，将弱的 电信号转换为脉冲个数的变化，通过检测脉冲的个数， 达到检测弱电信号的目 的。 检测单元 642可以采用一些集成芯片， 例如 TS555芯片等等， 如图 9所示为 本发明实施例采用 TS555的检测跳纤连接状态的电路图。 并且通过电信号的脉 冲数判断跳纤与第一端口或第二端口的连接质量。 由于 0DF中连接有大量的跳 纤， 而对跳纤进行插拔或更换连接端口的操作以后可能没有及时记录， 因此可 以对每个端口进行实时检测 ,进而实时监控出与每个端口所连接端口的变化情 况，在检测之后可以通过记录模块 65记录对端口目前连接的端口对应的端口标 识进行记录或更新， 同时记录端口之间连接的状态以及连接的质量情况。若出 现端口连接松动或脱落等情况可以及时发出报警信息，提示管理人员及时进行 相应处理。

图 10为本发明一个实施例提供的跳纤连接状态检测系统结构示意图， 如图
10所示， 该系统包括： 信号产生装置 1和检测装置 2; 其中， 信号产生装置 1用 于生成与第一端口对应的光信号， 并通过第一光纤将光信号发送至第二端口， 第一光纤连接跳纤的两端，跳纤的两端分别连接第一端口和第二端口；检测装 置 2用于根据是否接收到第一端口通过第一光纤发送至第二端口的光信号判断 所述第二端口与所述第一端口的连接状态， 并若接收到光信号， 则根据光信号 获取第一端口对应的端口标识。
为了对 0DF和局域网端的每个端口进行实时检测 , 实时监控每个端口与其 他端口的连接情况， 可以将该系统与每个端口相连接， 该系统与每个端口之间 可以采用第一光纤连接， 该第一光纤可以为 P0F , 也可以为其他类型大数值孔 径的光纤。 这样， 在 0DF和局域网端之间连接的任意两个端口上都分别连接有 跳纤连接状态检测系统 , 令 0DF和局域网端之间连接的任意两个端口分别为第 一端口和第二端口 , 第一端口和第二端口分别连接有信号产生装置 1和检测装 置 2。 若需要对第一端口和第二端口之间的连接状态进行检测， 首先采用信号 产生装置 1生成与第一端口对应的光信号， 并将该信号通过跳纤发送至第二端 口， 若与第二端口连接的检测装置 2接收到该光信号， 则检测装置 2可以进一步 通过该光信号识别出与第二端口连接的第一端口的端口标识， 即端口号， 获知 第二端口正处于与哪个端口连接的状态， 若检测装置 2无法接收到该光信号， 则第一端口和第二端口之间处于断开状态。 同样， 对于任何一个端口， 都可以 通过接收到的光信号检测出该端口与哪个端口处于连接状态。
