Description

射频识别交互方法及射频识别系统 技术领域
本发明涉及无线通信领域, 具体涉及一种射频识别交互方法及射频识 别系统。 背景技术 射频识别 (RFID, Radio Frequency Identify ) 系统包括标签和读写器。 是一种非接触式的自动识别技术, 它通过射频信号自动识别目标对象并获 取相关数据, 识别工作无须人工干预, 可工作于各种恶劣环境。 RFID技术 可识别高速运动物体并可同时识别多个标签, 操作快捷方便。
射频识别系统包括无源射频识别和有源射频识别, 两者的本质区别在 标签端。 前者标签是从读写器发射波形中获取能量, 后者标签自身有能源 供应。
底层读写器协议 ( LLRP, Low Level Reader Protocol )是介于 RFID读 写器和射频用户终端之间的协议接口, 之所以被称为低层, 是因为它提供 了 RFID射频协议的控制, 即提供了射频协议访问和控制的功能, 它有如下 特点:
提供方法控制读写器读取产品电子代码( EPC, Electronic Product Code ) 信息和其它信息,写数据到标签中,并执行依赖于协议的其它命令,如 EPC C1G2中的 kill和 lock。
提供健壮的状态报告和错误处理机制。
提供扩展新的无线传输协议的功能。
获取读写器设备的能力。 在全球产品电子代码管理中心 (EPC global )组织定义的 EPC网络架 构中, LLRP协议位于过滤和收集层和读写器层之间 ,充当一个媒介的作用。 该协议提供了一个介于射频用户终端和读写器之间的标准接口, 不同的厂 商可以根据实际场景下发相应的消息操作读写器, 这样就实现了读写器接 口的标准化。 读写器和标签之间的操作主要有清点、 读、 写。 清点就是获取场内标 签的 EPC码,读和写就是将清点到的标签,对特定的存储区进行读写操作。 进而实现实际业务需求。 射频用户终端通过下发 LLRP 消息给读写器, 实 现读写器上述功能。 在清点操作中, 射频用户终端需要下发 DELETE_ROSPEC、 ADD_ROSPEC、 ENABLE—ROSPEC和 START—ROSPEC 消息; 在读写操作中, 射频用户终端需要下发 DELETE_ROSPEC、 DELETE—ACCESSSPEC 、 ADD—ROSPEC 、 ENABLE—ROSPEC 、 ADD_ACCESSSPEC、 ENABLE_ACCESSSPEC和 START_ROSPEC消息。 现有的 LLRP标准协议给出的射频用户终端和读写器主要有四条有关访问 操作 ( AO ) 的消息, 即添加 AO规则消息 ( ADD_ACCESS )、 使能 AO规 则消息( ENABLE_ACCESS )、 去使能 AO消息( DISABLE_ACCESS )、 删 除 AO规则消息( DELETE_ACCESS )。 图 1为现有的 LLRP标准协议给出 的 AO状态跳转图, 具体为: 当读写器收到 ADD_ACCESS后, AO处于未 使能(DISABLE )状态, 在收到射频用户终端下发 ENABLE_ACCESS后, AO状态跳转到激活(ACTIVE )状态, 只有处于此状态的 AO才能进行读 写等访问操作; 处于 ACTIVE 状态的 AO , 收到射频用户终端下发的 DISABLE_ACCESS后, 状态跳转到 DISABLE状态; 处于 DISABLE和 ACTIVE的 AO状态, 在收到 DELETE_ACCESS或者在停止访问操作条件 ( AccessStopCondition ) 满足时, 结束生命周期。 由上可知, 要实现射频用户终端和读写器之间的读写等访问操作, 必 须使 AO 的工作状态处于激活状态, 而使其处于激活状态时, 射频用户终 端下发的 AO消息包括添加 AO规则消息和使能 AO规则消息,只有在收到 使能 AO规则消息后, 才能转换到激活状态, 可见, 射频用户终端和读写 器之间的消息交互较多, 且效率较低。 发明内容 本发明要解决的主要技术问题是, 提供一种射频识别交互方法及射频 识别系统, 可减少射频用户终端和读写器之间交互消息的次数, 简化交互 流程, 提高处理效率。

本实施例提供的射频识别交互方法, 包括以下步驟:
射频用户终端发送添加访问操作规则消息( ADD_ACCESSSPEC )给读 写器。
这里, 所述 ADD_ACCESSSPEC包括: 访问操作属性信息; 其中, 所 述访问操作属性信息包括用于指示 AO工作状态的工作状态参数,还可以包 括访问操作的 ID参数, 访问操作的停止条件; 所述工作状态参数在本例中 的指示 AO工作状态为激活状态。
读写器接收到 ADD_ACCESSSPEC后, 添加相应的访问操作规则, 并 将 AO的工作状态设置为激活状态。
即在本例中, 读写器进行读、 写、 锁、 停止(或称作杀死)等访问操 作时,射频用户终端下发的 AO相关的信息只有一种状态,即激活( ACTIVE ) 状态, 读写器一旦接收到射频用户终端下发的 ADD_ACCESSSPEC, 就直 接将 AO的工作状态设置为激活状态,而并非像现有 LLRP协议设置为未使 能(DISABLE )状态, 因此不需要 ENABLE_ACCESS消息对其进行激活, 如此, 可减少射频用户终端和读写器之间消息交互的次数, 进而可简化二 者之间的交互流程, 提高系统处理的效率。
进一步的, 所述读写器接收到 ADD_ACCESSSPEC后, 将 AO的工作 状态设置为激活状态之前, 还包括: 对 ADD_ACCESSSPEC中访问操作属 性信息的工作状态参数进行验证, 若验证通过, 则将访问操作的工作状态 设置为激活状态, 以进行读、 写、 锁、 停止(杀死)等访问操作。
进一步的,所述射频用户终端发送 ADD_ACCESSSPEC给读写器之前, 还包括: 射频用户终端发送添加阅读操作规则消息(ADD_ROSPEC )给读 写器; 读写器接收到 ADD_ROSPEC后, 添加相应的阅读操作( RO )规则, 并反馈添加阅读操作规则响应 ( ADD_ROSPEC_RESPONSE )给射频用户 终端。此时 RO的工作状态为未使能状态,并根据射频用户终端访问读写器 的具体情况激活 RO的工作状态,其中,所述射频用户终端访问读写器的具 体情况包括射频用户终端单次访问读写器和射频用户终端周期性的访问读 写器, 具体如下:
当射频用户终端单次访问读写器时,射频用户终端发送 ADD_ROSPEC 给读写器之后, 还发送使能阅读操作消息( ENABLE_ROSPEC )给读写器; 读写器接收到 ENABLE_ROSPEC后,将 RO的工作状态设置为未激活 状态, 并反馈使能阅读操作响应( ENABLE_ROSPEC_RESPONSE )给射频 用户终端; 射频用户终端接收到 ENABLE_ROSPEC_RESPONSE后, 发送激活阅 读操作消息 ( START_ ROSPEC )给读写器;
读写器接收到 START_ ROSPEC后, 将 RO的工作状态设置为激活状 态, 并反馈激活阅读操作响应给所述射频用户终端。
当射频用户终端周期性的访问读写器时, 射频用户终端发送 ADD_ROSPEC给读写器之后, 还发送 ENABLE_ROSPEC给读写器;
读写器接收到 ENABLE_ROSPEC后,将 RO的工作状态设置为激活状 态, 并反馈 ENABLE_ROSPEC_RESPONSE给射频用户终端。
进一步的, 所述读写器接收到 ADD_ACCESSSPEC后, 还会对访问操 作属性信息包括的参数(例如访问操作的 ID参数, 访问操作的停止条件) 进行验证, 如验证通过, 且上述工作状态参数验证也通过, 则将 ADD_ACCESSSPEC访问操作属性信息添加到访问操作的存储队列中, 并 将该 ADD_ACCESSSPEC访问操作属性信息或该 ADD_ACCESSSPEC访问 操作属性信息的索引号添加到匹配队列中, 反馈添加访问操作规则成功响 应给射频用户终端。
在 ADD_ACCESSSPEC携带的访问操作的停止条件满足时; 读写器将 访问操作的工作状态设置为停止状态。
本例中, 读写器接收到射频用户终端发送的删除访问操作规则消息 ( DELETE_ACCESSSPEC )后, 将 AO的工作状态设置为停止状态。 具体 的, 所述射频用户终端发送 ADD_ACCESSSPEC给读写器之前, 还包括: 射频用户终端发送删除阅读规则消息( DELETE_ROSPEC )和 DELETE _ACCESSSPEC给读写器进行初始化过程,用于将上次访问时所用的 AO规 则和 RO规则删除;
读写器接收到 DELETE_ROSPEC和 DELETE _ACCESSSPEC后,删除 相应 的 RO 规则和 AO 规则 , 并反馈删除阅读规则 响应
( DELETE_ROSPEC_RESPONSE ) 和删除访问操作规则响应 ( DELETE _ACCESSSPEC_RESPONSE )给射频用户终端。
本例中还提供了一种射频识别系统,包括: 射频用户终端和读写器; 其 中, 所述射频用户终端和所述读写器按上述方法实现射频识别交互以完成 相应的功能操作。 下面结合具体的附图对本发明做进一步说明。
图 2所示为根据上述射频识别交互方法实现的 AO状态跳转图, 其中, 射频用户终端和读写器之间主要有两条 AO 相关的交互消息, 即 ADD_ACCESSSPEC 、 DELETE_ACCESSSPEC 。 当 读 写 器 收 到 ADD_ACCESSSPEC后, 读写器设置 AO的工作状态处于激活状态; 处于 此状态的 AO才能进行读写等访问操作; 处于 ACTIVE状态的 AO,在收到 DELETE_ACCESSSPEC 或者访问操作的停止条件满足时下发的 AccessStopCondition后,读写器设置 AO的工作状态为停止状态,从而结束 生命周期。
可见, 相对于标准的 LLRP协议, 本例中提供的方法简化了射频用户 终端和读写器之间 AO消息的交互次数和交互流程,由 AO状态由原来的未 使能状态和激活状态减少为只有一个状态, 即激活状态; 与图 1相比, 不 再需要交互 ENABLE_ACCESS、 DISABLE_ACCESS消息, 提高了读写器 的工作效率和系统访问性能。 下面分别对现有技术中 LLRP标准协议完成 访问时射频用户终端和读写器之间消息交互过程、 以及本例提供的完成访 问时射频用户终端和读写器之间消息交互过程进行分析:
图 3所示为 LLRP标准协议完成单次访问时射频用户终端和读写器之 间消息交互过程示意图, 射频用户终端和读写器之间共有七对消息交互才 能实现读写器的访问操作, 其中: 在初始化阶段有两对, 分别为射频用户 终端发送的删除 RO规则消息 ( DELETE_ROSPEC )、 删除 AO规则消息 ( DELETE_ACCESSSPEC ) 和读写器反馈的删除 RO 规则响应消息 ( DELETE_ROSPEC_RESPONSE ) 、 删 除 AO 规则 响 应 消 息 ( DELETE_ACCESSSPEC_RESPONSE ), 经上述初始化后, 射频用户终端 发送添加 RO 规则消息 ( ADD_ROSPEC )、 添加 AO 规则消息 ( ADD_ROSPEC ) 给读写器, 读写器接收到后进行相应规则的添加处理, 并反馈添加 RO规则响应消息 (ADD_ ROSPEC .RESPONSE )和添加 AO 规则响应消息 ( ADD_ACCESSSPEC_RESPONSE )给射频用户终端, 此时 的 AO工作状态为未使能状态( DISABLE ); 然后射频用户终端还需发送使 能 RO消息( ENABLE_ROSPEC )和使能 AO消息( ENABLE_ACCESSSPEC ) 给读写器,读写器接收到上述消息后,将 RO的工作状态设置为未激活状态, 将 AO 的工作状态设置为激活状态; 并反馈使能 RO 规则响应消息 ( ENABLE_ROSPEC_RESPONSE ) 和使能 AO 规则 响应 消 息 ( ENABLE_ACCESSSPEC_RESPONSE )给读写器;射频用户终端接收到上 述两个响应消息后,还需进一步发送激活阅读操作消息( START_ROSPEC ) 给读写器, 读写器接收到该消息后, 将 RO的工作状态设置为激活状态。
图 4所示为本例提供的完成单次访问时射频用户终端和读写器之间消 息交互过程示意图, 射频用户终端和读写器之间共有六对消息交互才能实 现读写器的访问操作, 其中: 在初始化阶段有两对, 分别为射频用户终端 发送的 DELETE_ROSPEC、 DELETE_ACCESSSPEC , 和读写器反馈的 DELETE_ROSPEC_RESPONSE、 DELETE_ACCESSSPEC_RESPONSE; 经 上述初始化后, 射频用户终端发送 ADD_ROSPEC、 ADD_ROSPEC给读写 器, 读写器接收到后进行相应规则的添加处理, 并反馈 ADD_ROSPEC .RESPONSE和 ADD_ACCESSSPEC_RESPONSE给射频用户终端, 此时的 AO 工作状态为激活 ACTIVE 状态; 然后射频用户终端只需发送 ENABLE_ROSPEC给读写器, 读写器接收到上述消息后, 将 RO的工作状 态设置为未激活状态, 并反馈 ENABLE_ROSPEC_RESPONSE给射频用户 终端; 射频用户终端接收到上述 ENABLE_ROSPEC_RESPONSE后, 发送 START_ROSPEC给读写器; 读写器接收到该消息后, 将 RO的工作状态设 置为激活状态。
由图 3和图 4可见, 本例中提供的方法在实现单次访问过程中, 减少 一 对 信 息 交 互 , 即 ENABLE_ACCESSSPEC 和 ENABLE_ACCESSSPEC_RESPONSE , 因此简化了交互流程, 更利于提高 系统的处理效率。
图 5所示的是 LLRP标准协议给出的周期性的读写等访问操作射频用 户终端和读写器之间的消息交互图, 与图 3 的区别在于, 在读写器接收到 ENABLE_ROSPEC消息后, 直接将 RO的工作状态设置为激活状态, 并不 需要射频用户终端发送 START_ROSPEC给读写器以激活 RO的工作状态。 因此在此过程中射频用户终端和读写器之间的消息交互只有六对。
图 6所示为本例给出的周期性的读写等访问操作射频用户终端和读写 器之间的消息交互图, 与图 4 的区别在于, 在读写器接收到 ENABLE_ROSPEC消息后, 直接将 RO的工作状态设置为激活状态, 并不 需要射频用户终端发送 START_ROSPEC给读写器以激活 RO的工作状态, 因此在此过程中射频用户终端和读写器之间的消息交互只有五对。
由图 6与图 5所示的交互过程可见本例中提供的方法在实现周期性访 问过程中 , 减少一对信息交互, 即 ENABLE_ACCESSSPEC 和 ENABLE_ACCESSSPEC_RESPONSE , 因此也使交互流程简化, 更利于提 高系统的处理效率。
图 7 所示是本例给出的读写器接到射频用户终端发送的 ADD_ACCESSSPEC 的处理流程图, 具体为: 读写器在接到射频用户终端 下发的 ADD_ACCESSSPEC后,对 ADD_ACCESSSPEC的访问操作属性信 息包括各参数(例如工作状态参数、访问操作的 ID参数等)进行参数校验, 若校验正确, 则将访问操作属性信息保存到 AO的存储队列, 由于此时 AO 处于 ACTIVE状态, 因此还将访问操作属性信息或访问操作属性信息的索 引号 (例如下标)直接保存到 AO 的匹配队列, 向射频用户终端反馈添加 访问操作规则成功响应, 此时 AO处于 ACTIVE状态, 可以进行读写等访 问操作。 若参数校验错误, 则直接向射频用户终端反馈参数错误的响应 ADD_ACCESS_RESPONSE。 图 8是本例给出的读写器访问操作流程图, 具体为: 当读写器清点到 一个标签后, 首先判断 AO 的匹配队列是否为空, 若为空, 则进行下轮清 点; 若不为空, 则进行标签访问匹配, 匹配内容包括 RO、 天线、 协议等, 若匹配成功, 则可以进行读写等访问操作, 否则进行下轮清点。 由上可知, 本发明优化了 AO 的工作状态, 减少了信息交互数量, 简 化了信息交互流程, 提高了读写器的工作效率和系统的访问效率, 进而提 高了用户体验的满意度。
能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的 普通技术人员来说, 在不脱离本发明构思的前提下, 还可以做出若干简单 推演或替换, 都应当视为属于本发明的保护范围。
