Description

超高频的射频识别标签及系统，管理射频识别标签的方法 技术领域
本申请涉及但不限于标签识别领域，特别是一种超高频射频的识别标签及系统，管理射频识别标签的方法。
背景技术
在目标物体的数量巨大时，需要自动收集资源数据，同时可以从大量物体中迅速、准确地发现目标物体。
相关技术的识别方案如下：
技术方案1：使用打印/粘贴/绑扎在物体上的标签，该技术存在标签容易散落、丢失、字迹模糊、逐个翻看标签信息来找到目标端头，由于以上缺点导致查找效率低、容易出错等；
技术方案2：通过RFID(Radio Frequency Identification，射频识别)读写装置收集绑扎在货物上的RFID标签信息，进而达到统计货物数量的目的，目前较常见于超市、仓储和服装行业；
技术方案3：通过对RFID标签上连接LED，并连接一个电池给LED供电，或通过高频(13.56MHz)的近场耦合的方式给LED供电.
综上：技术方案1中，翻看和扫描标签导致货物需要搬挪等动作，耗时长且效率低。技术方案2中，能够自动收录物品数量和种类等信息，但仍无法高效、准确地发现目标物体。目标物体仍需依赖于合理、清晰的部署和放置。
技术方案3中，虽然可以快速发现目标物体,但是其供电的方式有缺陷,用有源电池供电不仅限制于电池寿命,并且标签的尺寸也受限于电池,而无源近场耦合的方式受限于作用范围,一般耦合的距离不会大于10厘米左右,而且受限于近场点对点协议,一次只能对应一个标签,应用范围和用途受限。
因此，如何在一堆货物中快速发现目标物体是亟待解决的问题。

图8为本申请提供的单个超高频的射频识别标签或指定超高频的射频识别标签的工作方法的流程图。读写装置启动，开始下发充电以及针对指定身份信息的超高频射频识别标签下发指令，超高频的射频识别标签收到指定身份信息后，将身份信息与其的身份信息核对，如果一致，使标签的LED常亮或闪烁，以指示其位置。超高频的射频识别标签向读写装置发送身份信息一致并且标签的LED点亮的信息(在此，该信息携带在接收上行射频信号1)。读写装置根据需要发出结束指令，所述结束指令设置成指示该超高频的射频识别标签的LED关闭。当超高频的射频识别标签接收到该关闭指令并实施将LED关闭后，超高频射频识别标签发送其LED已关闭的状态信息(在此， 该信息携带在接收上行射频信号2)给读写装置。
图9为本申请提供的读写设备与超高频射频识别标签装置进行交互的方法的示意图。如图9所示，读写装置与RFID标签通过无线方式进行信息交互和比对，并按约定机制点亮或熄灭LED。读写装置发出下行射频信号至超高频的射频识别标签，其中超高频的射频识别标签指具有LED的RFID标签；超高频的射频识别标签收到下行射频信号后，向读写装置发送携带有其身份信息的上行射频信号。然后读写装置根据回复的上行射频信号中携带的RFID标签的身份信息对指定RFID标签下发控制其LED点亮的信号，RFID标签收到所述控制其LED点亮的信号后，首先核对控制其LED点亮的信号携带的身份信息是否与RFID标签的身份信息一致，如果一致的话，超高频的射频识别标签中的LED被点亮，以醒目指示该标签所在位置，进而指示目标物体所在的位置。注意，不管LED是点亮还是不点亮，超高频的射频识别标签均不反射回复上行射频信号。亮灯完毕后，读写装置可以向超高频的射频识别标签发送关闭命令，以关闭LED所有的超高频的射频识别标签均收到所述关闭指令，只有其LED被点亮的超高频的射频识别标签才关闭LED。
在资源管理系统中，还可将包括但不限于目标物体的ID信息、入库信息、物体简要特征、资源收集人、资源收集时间等信息一并录入资源管理系统中。
本申请提供的超高频的RFID标签系统中，读写设备发送下行射频信号，其中下行射频信号包括目标物体的RFID的身份信息，RFID标签将目标物体的RIFD的身份信息与RFID标签的身份信息进行比对，如果一致，则控制其的光发射器发光，进而使用户容易找到目标物体，实现简单方便，硬件成本低。
图10为本申请提供的一个读写装置对多个无源发光RFID标签的LED进行轮留点亮的方法的流程图。读写装置启动和广播下发指令，要求收集所有RFID标签的身份信息。当覆盖范围内无源发光标签收到该指令时，启动P2MP(point 2multiple point，点对多点)流程，以进行依次反射回复，多个标签将自身身份信息反馈给读写装置，读写装置接受多个标签的身份信息(称为接收上行射频信号)。对于RFID点亮标签身份信息，在完成一次收集后， 可存储到读写装置自带的存储卡上。读写装置收集RFID标签的身份信息后，指示多个目标RFID标签的LED依次点亮。该方法从此步骤开始与图9所示点亮单个RFID标签的LED的方法一致，本文不再赘述。
本发明实施例另外提供一种计算机可读存储介质，存储有计算机可执行指令，所述计算机可执行指令被执行时实现上述方法。
综上可以看出，在本申请中，读写装置收集超高频射频识别标签中的身份信息。也可将收集到的或事先已录入和存储到读写装置存储卡中的身份信息发送给超高频射频识别标签，如果超高频射频识别标签中的身份信息与下行射频信号中携带的身份信息一致，超高频射频识别标签中的LED点亮。用此方法可以实现两种目标：1)通过收集超高频的射频识别标签中的身份信息，自动收录和统计货物/资源信息；2)通过读写装置下发和比对身份信息，点亮无源发光标签中LED，从而使用户准确定位到具有指定身份信息的目标物体，提高查找目标物体的效率。
