Description

三态电子标签 技术领域
本发明涉及一种电子标签， 特别涉及能够提供远距离读写状态、 近距离 读写状态和无法读写状态的三态电子标签。 背景技术
电子标签是射频识别系统的数据载体， 它由标签天线和标签专用芯片组 成。 每个标签都具有全球唯一的电子编码， 贴附在物体上以标识目标对象。 目前， 随着电子标签技术的快速发展， 电子标签被应用于更加广泛的流通领 域和识别应用中。
电子标签的天线在标签与读写器实现数据通信的过程中，起关键性作用。 一般来说， 标签的读写距离是指工作时标签与读写器之间的距离， 其距离近 可仅为毫米级， 远则可达 10米以上。
目前， 市面上的无线电子标签一般都是由标签芯片和固定天线组成， 由 于天线的增益固定， 所以标签的读写距离的有效范围固定， 如果超出天线增 益的有效范围， 则无法对标签进行读写。 发明的公开
本发明鉴于上述问题而完成， 其目的在于提供一种三态电子标签， 能够 使电子标签实现远距离读写、 远距离无法读写的近距离读写和无法读写等三 种状态， 使其在物联网应用中发挥更积极的作用。
本发明的三态电子标签， 其特征在于：
三态电子标签包括标签芯片、用于接收 /发射无线波的近态标签天线和远 态标签天线，上述近态标签天线与上述标签芯片采用可分离的方式导电连接， 上述远态标签天线和上述近态标签天线采用可分离的方式导电连接。
本发明的三态电子标签， 其特征还在于：
当处于所述标签芯片与所述近态标签天线连接， 且所述近态标签天线与 所述远态标签天线连接的状态时， 所述标签芯片的天线为所述近态标签天线 和所述远态标签天线的组合天线， 形成能够从相对较远距离处读写标签的状 态； 标签天线作为所述标签芯片的天线， 形成相对较近距离处读写标签的状态， 即相对较远的距离无法读写标签；
和当处于所述标签芯片与所述近态标签天线和所述远态标签天线均不连 接的状态时， 所述标签芯片不具有天线， 形成无法读写标签的状态。
根据本发明， 所述三态电子标签能够提供更丰富的应用功能。 可满足于 物品身份识别、 生产制造、 门禁、 库存、 物流、 批发、 零售、 及售后等各个 环节的需要， 例如： 远距离读写状态可满足门禁、 仓储、 物流、 批发等应用 环节的需要； 近距离读写状态可满足零售、 售后等应用环节的需要； 无法读 写状态对应防伪等应用环节。 附图的筒要说明

实现本发明的最佳方式
以下， 参照附图， 对本发明的三态电子标签进行详细说明。
图 1是本发明的一个实施例的三态电子标签的示意图。 如图 1所示， 近 态标签天线（2)采用可分离的、 闭环的方式与标签芯片（1)导电连接； 远态标 签天线（3)和近态标签天线（2)采用可分离的方式导电连接， 因为合成的天线 能够获取更大的电磁波有效增益，因此能够从远距离处对电子标签进行读写， 即三态电子标签处于远距离读写状态。 此时， 三态电子标签能够被位于读写 距离内的多个读写器读写。 所谓读写距离， 指的是能够对标签进行读写操作 的有效距离的最大值。
近态标签天线（2)和远态标签天线（3)的形状可以根据使用的要求来决 定， 而并非限定于上述情况，本实施方式只例示了其中一种可行的实施方式。
图 2为根据本发明的一个实施例的三态电子标签处于近距离读写状态时 的示意图， 其中， 远态标签天线（3)已从第一可分离的连接边界（4)处与近态 标签天线（2)分离，标签芯片（1)仅与近态标签天线（2)连接， 因此只能从近距 离对标签进行读写， 即， 三态电子标签处于近距离读写状态。 此时， 三态电 子标签能够被位于读写距离内的多个读写器读写。
图 3为根据本发明的一个实施例的三态电子标签中标签芯片与远态标签 天线（3)和近态标签天线（2)的无连接状态的示意图。 如图 3所示， 继图 2所 示的近距离读写状态下， 近态标签天线（2)从第二可分离的连接边界（5)处与 标签芯片（1)分离， 此时， 标签芯片不与天线连接， 处于无法读写状态。
在实际应用中， 首先， 近态标签天线（2)连接至标签芯片 （1 ) 以及远态 标签天线（3) ,近态标签天线（2)和远态标签天线（3)的组合构成三态电子标签 的天线，使三态电子标签处于远距离读写状态，将远态标签天线（3)分离之后， 近态标签天线（2)成为三态电子标签的天线，三态电子标签从远距离读写状态 切换成近距离读写状态；再将近态标签天线（2)分离之后，三态电子标签不再 具有天线， 从近距离读写状态切换成无读写状态。 这样， 实现了三态电子标 签的远距离读写、 近距离读写、 无信号 （即， 无法读写）等三种状态， 应用 这三种状态， 实现对标签标识物的精细管理。
下面， 对于本发明的三态电子标签的应用场合进行说明。
例如， 将三态电子标签以一对一的关系安装标贴在货物上。 当货物在运 输、 进出大门等物流过程中； 在货物仓储、 盘点操作时， 三态电子标签的远 态标签天线（3)和近态标签天线（2)同时存在， 处于远距离读写状态。 该远距 离读写状态可以将扫描距离设定为例如 1 0米， 即， 当将扫描器设置在距离货 物 1 0米范围内， 能够在短时间内扫描到所有货物， 并且统计、记录该批货物 的踪迹， 同时近距离扫描器可以就单一货物做核查。
当从货架取下货物准备销售时，沿着第一可分离的连接边界（4)将三态电 子标签的远态标签天线（3)分离， 此时， 三态电子标签仅由标签芯片（1)和近 态标签天线（2)构成，处于近距离读写状态。该近距离读写状态可以将扫描距 离设定为例如 1 0厘米， 此时， 设置于距离货物 1 0米远的扫描器无法扫描到 该货物， 而仅仅由设置在距离货物 10厘米远的扫描器扫描到该货物，并且记 录该货物此时为近距离读写状态。
当货物出货后， 三态电子标签是该货物的唯一身份证明， 货物使用者可 以借助该三态电子标签， 要求销售方提供售后服务。 无论何种理由， 如果近 态标签天线（2)被去除， 只剩余不具有天线的标签芯片（1)时， 三态电子标签 处于无信号状态， 即无法读写状态， 即使将扫描器设置在距离货物 10厘米或 更近的位置上， 也无法扫描到该电子标签， 此时销售方可以将该货物视同假 冒产品， 拒绝提供售后服务， 以此达成货物防伪的效能。
而且， 在每一次扫描器识别三态电子标签的不同状态时， 都会将该状态 信息发送到信息管理中心， 从而用户 （即管理人员） 能够通过网络随时了解 货物的状态， 并且基于所获得的状态信息进行管理， 有利于提高管理效率。
除了以上列举的例子之外， 本发明的三态电子标签还能够应用于更广泛 的领域。 例如在制造、 包装、 仓储、 物流、 零售批发、 食品溯源、 文档管理 等领域中， 都能够得到广泛应用。 上文结合具体实施例对本发明进行了具体 的说明， 但本发明申请并不局限于上文所述的具体实施例。 在不脱离本发明 的精神的情况下， 本领域技术人员根据具体的应用需要， 可以对本发明做出 变型或者改进， 但这些变型或者改进均落入本发明申请的保护范围之内。 工业应用性
根据本发明， 所述三态电子标签能够提供更丰富的应用功能。 可满足于 物品身份识别、 生产制造、 门禁、 库存、 物流、 批发、 零售、 及售后等各个 环节的需要， 例如： 远距离读写状态可满足门禁、 仓储、 物流、 批发等应用 环节的需要； 近距离读写状态可满足零售、 售后等应用环节的需要； 无法读 写状态对应防伪等应用环节。
