Description

无源光学标签、光读写装置及智能光分配网络 技术领域
本发明涉及通信领域，具体而言，涉及一种无源光学标签、光读写装置及智能光分配网络。
背景技术
在智能ODN的相关技术中存在多种标签技术，一种是接触式标签技术，另一种是非接触式标签技术，分别如图1和图2所示。
图1是根据相关技术的接触式标签技术的示意图，如图1所示，采用接触式标签，比较典型的是1-Wire接口，或EEPROM接口。另外，需要给标签供电。接触式标签技术对于标签结构的设计及可靠性提出了更高的要求，同时在某些改造场景中因为物理连接而不够灵活。
图2是根据相关技术的非接触式标签技术的示意图，如图2所示，采用非接触式标签，比较典型的是射频识别(Radio Frequency Identification，简称为RFID)技术。由于射频识别标签的工作原理，即切割磁力线产生感应电流，因此射频识别标签线圈需要有一定的工作面积以产生足够的感应电流驱动其芯片正常工作，同时，光读写装置的工作线圈也要有一定的工作面积，从而导致相邻的RFID也会受到感应，造成相互干扰，因此该技术不适合用于密集的工作环境。

本发明实施例的上述***，优选地应用在光纤网络中。下面以在光线网络中为例，对本发明实施例进行描述。
参见图6所示***，对标签信息进行读写是由光读写装置中控制芯片的发起的，无源光学标签主要存储身份及位置信息，这些信息是由光读写装置赋予的，也可以由光读写装置对其进行修改，无源光学标签工作的电源是由其光电池通过光转换而来的，可以通过光读写装置对其充电，也可以通过外界光源对其充电。
参见图5所示的光读写装置，它可以是一个有源设备。光发射器的作用是给无源光学标签充电以及发送数据信号给无源光学标签；而光接收器的作用是接收由无源光学标签发送过来的光信号；最后芯片可以接收外部网管的指令，启动对无源光学标签 的读写，对于空白的无源光学标签可以赋予其身份和位置信息，也可以对已有身份信息的标签进行阅读和比对，还可以对标签进行相应信息的修改，最后光读写装置将相关信息传送给网管或控制中心保存。
参见图3或4所示无源光学标签，它本身是无源的。光电池接收光读写装置或其他外部光源的光将其转换为电源供其他几个单元使用，光发射器根据控制芯片的要求，发送回复信号；光接收器将接收到的光读写装置的指令转换为电信号传送给芯片；芯片能对指令进行处理，启动光发射器进行回复，同时它具有信息存储的功能。
其中，参考图4的无源光学标签，光伏电池接收器将光读写装置或其他外部光源的光将其转换为电源供其他几个单元使用，同时将光读写装置的数据信号转化为其输出电压的变化的电信号传输给芯片，芯片对指令进行相关处理，启动光发射器进行回复，同时它具有信息存储的功能。
在本发明实施例中，智能光分配网络，包括：包括多个连接器端口的接线盒；多个线缆，每一个线缆包含相对的末端以及固定到每一个末端上的相应连接器，每一个连接器被配置为可拆卸地固定在连接器端口内，其中，每一个连接器上设置有一个上述无源光学标签，其中，每一个无源光学标签存储有自身的标签身份信息；每一个连接器端口上设置有一个光读写装置，并且每一个光读写装置设置在当连接器被***在连接器端口时，使光读写装置与该连接器上无源光学标签正对的位置；每一个光读写装置，设置为对自身对应的无源光学标签进行读写操作；每一个无源光学标签，设置为响应自身对应的光读写装置的读写操作。
通过本发明实施例，采用无源光学标签，实现了非接触式检测，并且在密集场景下，不会存在干扰。
在本发明实施例的一个实施方式中，上述光读写装置，还设置为与网络管理***进行通信，接收网络管理***的消息和/或向网络管理***发送信息。

图9是根据本发明实施例的光学连接头的示意图，如图9所示，首先将无源光学标签安置在光学连接头上，当光连接头***连接盒时，光读写装置在标签上方，表示该光纤已经处于连接的状态，而这时标签正好处于光读写装置的下方。
在使用本方法对标签进行读写时，***工作流程如图10所示，具体过程如下：
首先光读写装置接收到网管或控制中心的指令对标签进行读写，控制芯片开始启动读写过程，首先对无源光学标签进行充电，然后开始执行如下测试步骤：
步骤S1002，向无源光学标签发出问询指令，如：标签的状态。
步骤S1004，标签回复目前状态，如：空白或已有身份信息。
步骤S1006，如果是空白身份信息，或者已有身份和位置信息需要清零，光读写装置分配一个身份信息给无源光学标签；如果是已有正确身份信息，光读写装置要求无源光学标签报出身份信息。
步骤S1008，无源光学标签执行完毕后报告自己目前的身份信息。
步骤S1010，光读写装置对身份信息进行验证，如果不符合要求，光读写装置重新赋予无源光学标签新的身份信息，无源光学标签重复步骤S808，然后光读写装置对信息重新评估如果不满意，再重复步骤S806至步骤S810；如果反馈的信息符合要求，则光读写装置，发出：《结束》的指令；
步骤S1012，无源光学标签收到结束指令后，回复：《结束，确认》。
本发明实施例的无源光学标签与读写装置***。如图6所示，也可以用在多个短距应用场景中，如：交通卡、银行卡、单位工卡以及旅馆客人房门卡等。
首先可以将无源光学标签安置在这些卡片上，读写装置根据不同的要求安置在不同的位置上，如：交通卡读写装置可以安置在出租汽车，公交车上或地铁站；银行卡读写装置可以安置在银行的网点上；单位工卡的读写装置可以在安置在大楼的门口，方便员工打卡；旅馆客人房门卡读写装置可以安置在门锁上，方便客人打开房门。
总之，这些短距的应用场景也非常适合本发明实施例的装置。
