本申请要求于 2011年 3月 29日提交中国专利局、 申请号为 201110078374.1、发明名称 为 "光信号控制方法、 光信号控制系统和光背板系统" 的中国专利申请的优先权， 其全部 内容通过引用结合在本申请中。
说 技术领域
本发明涉及光通信技术领域， 特别涉及一种光信号控制方法、 光信号控制系统和光背 板系统。
书 背景技术
线路板是指插在背板槽位上的印刷线路板， 通常包括： 业务板、 交换板和主控板。 其 中， 插在背板业务槽位的叫业务板， 插在背板交换槽位的叫交换板， 插在背板主控槽位的 叫主控板。 交换板中包含有交换芯片， 在集中交换的系统中， 除交换板以外的其余线路板 上的数据信号会连接到交换板的交换芯片上， 从而实现各槽位之间的数据交换； 在全互连 的系统中， 各业务槽位的数据直接链接； 主控板是起控制和管理作用的线路板， 可以独立 存在， 也可能与交换板合一。
随着信号速率的提升， 受介质损耗、 串扰以及功耗的限制， 采用传统电背板变得越来 越困难， 而光背板系统具有低损耗、 低串扰、 高密度以及通道特性与速率无关等优点， 因 此， 与电背板方案相比， 光背板方案能达到更高的系统容量， 并可实现平滑升级。
通讯系统一般安装在机架上， 且背板与安装面垂直， 以便于操作者插拔线路板。 背板 上的每个槽位都安装有连接器， 有时是很多个连接器， 用于连接线路板和背板。 当背板满 配置时， 所有槽位都插有线路板。 当背板没有满配置时， 某些槽位插有线路板， 其余槽位 没有插线路板。 在光背板系统中， 如果系统正处于工作状态， 且有线路板从光背板上拔出， 则会造成拔出线路板的槽位上的光连接器有光信号泄漏， 且正对着操作者， 从而会对操作 者造成伤害， 特别是对眼睛造成伤害。 发明内容 为了解决现有技术光背板系统中光信号泄露的问题， 本发明实施例提供了一种光信号 控制方法、 光信号控制系统和光背板系统。 所述技术方案如下：
一种光信号控制方法， 所述方法包括：
检测光背板上是否有线路板拔出；
如果有线路板拔出， 则查询与被拔出的线路板所在槽位相连的其它线路板的发送端口， 向所述发送端口发送第一控制指令， 所述第一控制指令用于通知关闭所述发送端口或者将 所述发送端口的输出功率调整为预设的阈值以下， 所述预设的阈值为指定的用于区分发送 端口是否处于工作状态的边界值。
一种光信号控制系统， 所述系统包括- 检测模块， 用于检测光背板上是否有线路板拔出；
控制模块， 用于如果所述检测模块检测出有线路板拔出， 则查询与被拔出的线路板所 在槽位相连的其它线路板的发送端口， 向所述发送端口发送第一控制指令， 所述第一控制 指令用于通知关闭所述发送端口或者将所述发送端口的输出功率调整为预设的阈值以下， 所述预设的阈值为指定的用于区分发送端口是否处于工作状态的边界值。
一种光背板系统， 包括光背板和线路板， 所述光背板系统包括所述光信号控制系统， 所述光背板具有两个以上槽位， 所述两个以上槽位中的至少一个槽位为被拔出线路板所在 的槽位， 其余槽位中的至少一个槽位插有其它线路板， 所述光信号控制系统位于所述两个 以上槽位中的无光连接器的槽位上或有光连接器的槽位上。
本发明实施例提供的技术方案的有益效果是：
通过检测光背板上是否有线路板拔出， 在有线路板拔出时， 向被拔出线路板所在槽位 相连的其它线路板的发送端口， 发送第一控制指令， 通知关闭该发送端口或将其输出功率 调整为预设阈值以下， 从而防止了被拔出线路板所在槽位上的光连接器有光信号泄漏， 避 免了对操作者尤其是眼睛造成伤害。 另外， 通过关闭未工作的光通道可以降低系统的功耗， 而且， 通过基于槽位进行控制， 而不是基于每条光路进行控制， 也无需为每条光路增加光 路检测， 从而极大地降低了复杂性和系统成本。 附图说明

本实施例中， 控制模块 602可以位于无光连接器的槽位上， 如位于主控板所在的槽位 上， 或者位于有光连接器的槽位上， 如位于交换板所在的槽位上， 或者位于交换板和主控 板合一后所在的槽位上。
本实施例还提供了一种光背板系统， 包括上述任一种实施方式下的光信号控制系统， 其中， 所述光背板具有两个以上槽位， 所述两个以上槽位中的至少一个槽位为被拔出线路 板所在的槽位， 其余槽位中的至少一个槽位插有其它线路板， 所述光信号控制系统位于所 述两个以上槽位中的无光连接器的槽位上或有光连接器的槽位上。

参见图 7， 本实施例提供了一种光背板系统， 通过在位检测信号进行控制， 该系统包括 光背板 701、 线路板 702和主控板 703， 并且还包括光信号控制系统， 该光信号控制系统包 括- 在位检测控制器 704， 用于检测光背板 701上的在位检测信号； 如果该在位检测信号为 指定的第一电平， 则判定有线路板 702从该光背板 701拔出； 如果该在位检测信号为指定 的第二电平， 则判定有线路板 702插入该光背板 701 ;
其中， 指定的第一电平为高电平， 第二电平为低电平； 或者， 第一电平为低电平， 第 二电平为高电平。
发送端口控制器 705， 用于如果在位检测控制器 704检测出有线路板 702拔出， 则查询 与被拔出的线路板 702所在槽位相连的其它线路板 702的发送端口， 向该发送端口发送第 一控制指令， 该第一控制指令用于通知关闭该发送端口或者将该发送端口的输出功率调整 为预设的阈值以下， 该预设的阈值为指定的用于区分发送端口是否处于工作状态的边界值。
本实施例中， 光背板 701 的每个槽位上都设置至少一个在位检测信号， 即电平信号。 在位检测控制器 704可以根据每个槽位的在位检测信号判断出该槽位上是有线路板插入还 是有线路板拔出。 其中， 在位检测控制器 704的检测原理如图 8所示。 图中的开关为示意 性的开关， 不代表真正的开关， 代表的是线路板的插拔状态， 该开关连通时代表线路板插 入即在位， 此时， 线路板与光背板中的地相连， 则为低电平； 该开关断开时代表线路板拔 出即悬空， 此时， 线路板不与光背板中的地相连， 相连的是线路板中的两个电阻1， 所以为 高电平。 根据该原理， 在位检测控制器可以根据在位检测信号为高电平， 判断出有线路板 从光背板拔出； 根据在位检测信号为低电平， 判断定出有线路板插入光背板。
本实施例中， 进一步地， 发送端口控制器 705还用于： 如果在位检测控制器 704检测 出有线路板插入， 则查询与被插入的线路板所在槽位相连的其它线路板的发送端口， 向该 发送端口发送第二控制指令， 通知打开该发送端口或者将该发送端口的输出功率调整为上 述预设的阈值以上。
本实施例中， 在位检测控制器 704在检测到某个槽位的电平发生变化后， 可以生成一 个控制指令给发送端口控制器 705， 以指示对发送端口的操作。 当在位检测控制器 704检测 到第一电平时， 判定有线路板拔出， 可以发送一个第一控制指令给发送端口控制器 705， 发 送端口控制器 705 收到该第一控制指令后， 可以查询发送端口与槽位关系映射表， 找到与 被拔出的线路板所在槽位相连的其它线路板的发送端口， 发送该第一控制指令给查找到的 发送端口， 通知关闭该发送端口或者将该发送端口的输出功率调整为预设的阈值以下。
当在位检测控制器 704检测到第二电平时， 判定有线路板插入， 可以发送一个第二控 制指令给发送端口控制器 705， 发送端口控制器 705收到该第二控制指令后， 可以查询发送 端口与槽位关系映射表， 找到与插入的线路板所在槽位相连的其它线路板的发送端口， 发 送该第二控制指令给查找到的发送端口， 该第二控制指令用于通知打开该发送端口或者将 该发送端口的输出功率调整为上述预设的阈值以上。
这样， 当线路板拔出时， 与此槽位连接的所有其余槽位上线路板的发送端口均关闭， 从而实现对操作员的保护； 当线路板插上时， 与此槽位相连的其余槽位上的线路板的发送 端口开始发送光信号， 从而接通与此槽位相连的信号通道。
本实施例中， 在位检测控制器 704位于主控板上。 发送端口控制器 705可以位于无光 连接器的槽位上， 如位于主控板所在的槽位上， 或者位于有光连接器的槽位上， 如位于交 换板所在的槽位上， 或者位于交换板和主控板合一后所在的槽位上， 本发明实施例对此不 做具体限定。 发送端口控制器 705可以是主控板上的 CPU, 发送端口与槽位关系映射表可 以存储在主控板上的存储介质中， 如机械硬盘， 固体硬盘等。 发送端口与槽位关系映射表 可以如下面的表 1所示。
表 1
Figure imgf000012_0001
表 1所示的是 Ν个槽位中发送端口与槽位的对应关系。 1,2,3···Ν代表光背板上有 Ν个 槽位， 可以插入 Ν个线路板。 nl,n2,n3,n4,n5……等代表 m槽位上的发送端口号， m介于 1 和 N之间。 例如， 表 1中的第 3列代表与槽位 2相连的发送端口有哪些， 包括： 槽位 1的 nl,n2发送端口， 槽位 3的 n6发送端口， …， 以及槽位 N的 n3， n4发送端口。 下面举例具 体说明， 假设光背板上插有 N个线路板， 发送端口与槽位的对应关系如表 1所示。 如果槽 位 2上的线路板拔出， 则在位检测信号变化为第一电平， 主控板上的在位检测控制器可以 通过电连接器检测到该第一电平， 因此， 会发送一个第一控制指令给发送端口控制器， 发 送端口控制器收到后查找表 1， 得到第 3列中的所有发送端口， 包括： 槽位 1的 nl,n2发送 端口， 槽位 3的 n6发送端口， …， 以及槽位 N的 n3， n4发送端口， 从而向该查找到的所 有发送端口发送该第一控制指令， 从而保证在拔下槽位 2上的线路板时， 该槽位上无光信 号泄漏， 保证了操作者的安全。
本实施例中的线路板包括但不限于： 业务板、 交换板和主控板， 以及交换板和主控板 合一的线路板。
本实施例提供的上述光背板系统， 通过在位检测控制器检测光背板上是否有线路板拔 出， 在有线路板拔出时， 由发送端口控制器向被拔出线路板所在槽位相连的其它线路板的 发送端口， 发送第一控制指令， 通知关闭该发送端口或将其输出功率调整为预设阈值以下， 从而防止了被拔出线路板所在槽位上的光连接器有光信号泄漏， 避免了对操作者尤其是眼 睛造成伤害。 另外， 通过关闭未工作的光通道可以降低系统的功耗， 而且， 通过基于槽位 进行控制， 而不是基于每条光路进行控制， 也无需为每条光路增加光路检测， 从而极大地 降低了复杂性和系统成本。 实施例 5
参见图 9， 本实施例提供了一种光背板系统， 通过在位检测信号和插稳检测信号进行控 制， 该系统包括光背板 901、 线路板 902和主控板 903， 并且还包括光信号控制系统， 该光 信号控制系统包括- 在位检测控制器 904， 用于检测光背板 901上的在位检测信号；

发送端口控制器 906， 用于如果插稳检测控制器 905检测出有线路板 902拔出， 则查询 与被拔出的线路板 902所在槽位相连的其它线路板 902的发送端口， 向该发送端口发送第 一控制指令， 该第一控制指令用于通知关闭该发送端口或者将该发送端口的输出功率调整 为预设的阈值以下， 该预设的阈值为指定的用于区分发送端口是否处于工作状态的边界值。

当在位检测控制器 904检测到某个槽位的在位检测信号为第四电平， 并且插稳检测控 制器 905检测到该槽位的插稳检测信号也为第四电平时， 则插稳检测控制器 905判定有线 路板插入， 可以发送一个第二控制指令给发送端口控制器 906。发送端口控制器 906收到该 第二控制指令后， 可以查询发送端口与槽位关系映射表， 找到与被插入的线路板所在槽位 相连的其它线路板的发送端口， 从而发送该第二控制指令给查找到的发送端口， 通知打开 该发送端口或者将该发送端口的输出功率调整为上述预设的阈值以上。
这样， 当线路板拔出时， 与此槽位连接的所有其余槽位上线路板的发送端口均关闭， 从而实现对操作员的保护； 当线路板插上时， 与此槽位相连的其余槽位上的线路板的发送 端口开始发送光信号， 从而接通与此槽位相连的信号通道。
