Description

射频读卡器和射频识别方法 技术领域
本申请涉及射频识别技术领域，具体地，涉及一种射频读卡器和射频识别方法。
背景技术
射频识别(Radio Frequency Identification，RFID)技术在工业场景和商业环境中被广泛应用，用于实现物品的识别与追踪等目的。RFID系统通常可分为有源(Active)和无源(Passive)两大类，以无源射频识别系统(Passive RFID System)为例，一个Passive RFID系统通常包括至少一个RFID读卡器、读卡器天线、可与RFID读卡器通信的服务器以及大量贴附于被追踪物品的RFID无源标签。
在RFID系统中，RFID读卡器(可简称为“读卡器”)发挥重要作用。一方面，读卡器通过读卡器天线获取额定范围内的RFID标签信息；另一方面，读卡器与服务器通信，将读取到的信息输出至服务器，同时也从服务器获取指令，从而达到目标识别、数据传输和过程控制等目的。
对于不同的应用场景或不同的应用目的，目前，可采用的读卡器产品大致有两种类型，一种为固定式读卡器，一种为便携式读卡器。固定式读卡器体积较大，因此往往被固定于特定位置使用，通常具有多个天线接口，有效读取范围大，适用于多标签、大范围的物品识别与追踪。与固定式读卡器恰好相反地，便携式读卡器的体积较小，大多使用单根效率较低的读卡器天线，有效读取范围较小，通常由操作人员手持并靠近标签读取信息，适用于单标签的近距离读写与追踪。
当前，在实际应用中，随着下一代无线通信技术的演进，与用户相关的应用场景的种类、数量大幅增长，这对RFID产品的性能提出了更高的要求，旧的RFID产品已不能满足实际使用需求。

图1示意性地示出了本申请实施例的一种射频读卡器500的外部效果示意图，该射频读卡器500包括可移动本体100和基座200，基座200上安装有多个天线300(图1中示出4个)，在一种实施方式中，天线300可采用大范围读取信息的全向天线。在其他实施方式中，天线300的数量还可以为1个、2个、6个、16个、更多或更少。
本申请实施例的射频读卡器500是一种可重构式RFID读卡器，原因在于：首先，基座200的外壳上具有安装组件，可将基座200安装在指定位置，例如，固定安装在屋顶、墙面、出入口的门框上等等，可通过天线300发射射频信号；其次，可移动本体100的壳体内部设置有读卡器芯片和微处理器，读卡器芯片的射频前端具有天线接口，可安装例如效率较低的电小天线；并且，可移动本体100既可以与基座200组合使用，也可以与基座200分离使用，例如可在基座的外壳上设置第一组装组件，并在可移动本体100的外壳上设置第二组装组件，第一组装组件与第二组装组件相对应，用于将可移动本体100可拆卸地组装在基座上。
基于上述可重构式的设计原理，当用户将可移动本体100安装在基座200上组合使用时，射频读卡器500的工作天线为基座200上的多个天线300(例如全向天线或适合的其他类型天线)，而当用户将可移动本体100从基座200上取下分离使用时，射频读卡器500的工作天线为可移动本体 100上安装的天线(例如电小天线或适合的其他类型天线)。
根据不同应用场景的使用需求，用户可灵活地选择射频读卡器500的组合模式或分离模式，在组合模式下基座200上的全向天线可读取大范围内的大量标签信息，在分离模式下用户手持可移动本体100读取近距离范围内的标签信息，实际上兼顾了旧有的固定式读卡器和便携式读卡器两者的优势，可重构式融合设计不仅使用方便，适用范围广，也可在一定程度上降低硬件成本。
图2示出了本申请实施例的射频读卡器处于分离工作模式下的结构状态示意图。图3示出了本申请实施例的射频读卡器处于组合工作模式下的结构状态示意图。以下结合附图对本申请实施例的射频读卡器的各个方面进行详细描述。
本申请实施例的射频读卡器包括可移动本体100和基座200，具体地，可移动本体100包括：射频读卡器芯片120、天线切换组件110和微控制器130，其中射频读卡器芯片120和天线切换组件分别与微控制器耦合，射频读卡器芯片具有至少一个第一天线接口(图2中示出1个)。基座200包括：天线匹配网络组件210和至少一个第二天线接口(图2中示出4个)，天线匹配网络组件210与至少一个第二天线接口耦合。
其中，可移动本体100的天线切换组件110用于实现在不同的情况下，射频读卡器可选择采用第一天线接口或者第二天线接口为工作天线接口。
在本申请的一种实施方式中，天线切换组件110可具有第一状态和第二状态；其中，在可移动本体100与基座200分离的情况下，天线切换组件110处于第一状态；在可移动本体100与基座200组合的情况下，天线切换组件110处于第二状态。
通过对天线切换组件110的状态进行控制，可使在可移动本体100与基座200分离的情况下，即天线切换组件110处于第一状态时，射频读卡器以第一天线接口为工作天线接口；并且，在可移动本体100与基座200组合的情况下，即天线切换组件110处于第二状态时，射频读卡器以第二天线接口为工作天线接口。
其中，基座200中的天线匹配网络组件210用于进行阻抗匹配，可使系统传输最大的信号能量，减小回波对信号质量和可用功率的影响。本申请实施例中的天线匹配网络组件210可采用本领域已有的天线匹配网络实现，对其功能及工作原理不再赘述。
本申请实施例的天线切换组件110可以通过多种实施方式实现，以下通过多个实施例进行详细描述。
实施例1
本实施例的射频读卡器包括如图2或图3所示的可移动本体100和基座200。本实施例中，射频读卡器芯片120具有一个第一天线接口。
在可移动本体100与基座200分离的情况下，如图2所示，天线切换组件110将射频读卡器芯片120上的一个第一天线接口与预配置的第一类天线连通；
在可移动本体100与基座200组合的情况下，天线切换组件110将射频读卡器芯片120上的一个第一天线接口与天线匹配网络组件210连通。
其中，天线匹配网络组件210还与至少一个第二天线接口耦合，第二天线接口上可安装第二类天线。
通过上述实施方式，用户在使用射频读卡器过程中，如果将可移动本体100从基座200上取下，则可移动本体100与基座200分离，这时天线切换组件110进入第一状态，其将第一天线接口与预配置的第一类天线连通，也就是以第一天线接口为工作接口，由第一类天线收发射频信号，读取标签信息。
如果用户将可移动本体100再组装回基座200上，使得可移动本体100与基座200组合，这时天线切换组件110进入第二状态，其断开第一天线接口与第一类天线之间的连接，而将第一天线接口与天线匹配网络组件210连通，这时，由于天线匹配网络组件210上的一个或多个第二天线接口上可安装第二类天线，因此射频读卡器以第二天线接口为工作接口，由第二类天线收发射频信号，读取标签信息。
以第一类天线为电小天线、第二类天线为全向天线为例，当用户将可移动本体100从基座200上取下之后，天线切换组件110将可移动本体100中的射频读卡器芯片120上的第一天线接口与电小天线连通，用户可手持可移动本体100在目标区域范围内移动，近距离地读取标签信息，方便地实现对标签的追踪和定位。
当用户将可移动本体100装回基座200上之后，天线切换组件110将可移动本体100中的第一天线接口与基座200中的天线匹配网络组件210接通，因而天线匹配网络组件210能够接收射频读卡器芯片120发出的射频信号，进而通过耦合的第二天线接口上的全向天线发射并接收射频信号，从而可对全向天线覆盖的范围内的标签进行追踪，完成两种工作模式的切换。
实施例2
本实施例的射频读卡器包括如图2或图3所示的可移动本体100和基座200。本实施例与实施例1的不同之处主要在于，射频读卡器芯片120具有多个第一天线接口，如射频读卡器芯片120内具有多个射频前端，每个射频前端均具有一个第一天线接口。这时，为所述的多个第一天线接口连接一多路切换组件(图中未示出)，多路切换组件可从多个第一天线接口中选通一个第一天线接口。具体地，多路切换组件与微处理器130连接，可根据微处理器130的指令在多个第一天线接口中选择一个第一天线接口 连通，其余第一天线接口均断开。
在本实施例中，在本体与基座分离的情况下，天线切换组件110将多路切换组件与第一类天线连通，在本体与基座组合的情况下，天线切换组件110将多路切换组件与天线匹配网络组件120连通，如此，可使得射频信号依次经过可移动本体100中的第一天线接口、多路切换组件、天线切换组件110、基座200中的天线匹配网络组件120和第二天线接口，最终到达第二类天线，从而完成两种工作模式的切换。
实施例3
本实施例的射频读卡器包括如图2或图3所示的可移动本体100和基座200。本实施例与实施例1的不同之处主要在于，本实施例的可移动本体100还包括切换开关(图中未示出)，切换开关与天线切换组件110耦合，用于控制天线切换组件110的状态，当切换开关被设置于第一档位时，其控制天线切换组件110切换至第一状态，从而以可移动本体100上的第一天线接口为工作接口；当切换开关被设置于第二档位时，其控制天线切换组件110切换至第二状态，以基座200上的第二天线接口为工作接口。
用户在使用本实施例的射频读卡器时，可通过该切换开关对读卡器的工作模式进行主动切换，举例来讲，用户将可移动本体100从基座上取下时，可将切换开关打至第一档位上，使天线切换组件110切换至第一状态，此时进入分离工作模式，用户可开始手持可移动本体100读取目标标签信息；用户将可移动本体100装回基座200上后，可将切换开关打至第二档位上，使天线切换组件110切换至第二状态，则射频读卡器进入组合工作模式，可开始读取周围较大范围内的标签数据。
实施例4
本实施例的射频读卡器包括如图2或图3所示的可移动本体100和基座200。本实施例与实施例3的不同之处主要在于，本实施例不是通过切换开关控制天线切换组件110的状态，而是通过安装位置感应组件来检测可移动本体100的位置，判断射频读卡器的工作状态。
具体地，如果位置感应组件检测到可移动本体100与基座200分离，则通知天线切换组件110切换至第一状态；如果位置感应组件检测到本体与基座组合，则通知天线切换组件切换至第二状态。
在一种可能的实施方式中，位置感应组件可采用多种元器件实现，例如可在可移动本体100和/或基座200上安装短路开关、红外感应器、接近开关中的至少一种，可检测可移动本体100是否组合安装在基座200的指定位置上。
将位置感应组件与微控制器耦合，当位置感应组件检测到本体与基座分离后，向微控制器发送第一信息，微控制器接收到第一信息后，向天线 切换组件发送第一指令，天线切换组件接收到第一指令后切换至第一状态；类似地，当位置感应组件检测到本体与基座组合后，向微控制器发送第二信息，微控制器接收到第二信息后，向天线切换组件发送第二指令，天线切换组件接收到第二指令后切换至第二状态，实现射频读卡器两种工作模式的切换。
实施例5
本实施例的射频读卡器包括如图2或图3所示的可移动本体100和基座200。本实施例中的基座200还包括天线扩展组件，其与天线匹配网络组件120耦合，还与至少一个第二天线接口耦合。天线扩展组件可将一个天线接口扩展为多个天线接口，可以为读卡器安装更多天线。
工作过程中，在射频读卡器的组合工作模式下，天线匹配网络组件120接收天线切换组件110传输的射频信号，通过天线扩展组件，射频信号可传输至各个第二类天线例如全向天线。
利用本实施例，通过将各个天线摆放于不同的空间位置可以增加读卡器的有效读取范围，提高读卡器性能。
实施例6
本实施例的射频读卡器包括如图2或图3所示的可移动本体100和基座200。本实施例中的基座200还包括电源管理组件，在射频读卡器的组合工作模式下，电源管理组件可为本体供电。例如，如果本体上设置有充电电池例如锂电池，电源管理组件可为本体的电池充电，当本体被取下单独工作时可具备足够的电量。
基于以上描述的实施例1-6中的任一实施例或多个实施例的组合，可执行射频识别方法，包括如下步骤：
S101，若可移动本体100与基座200被分离，控制天线切换组件110以射频读卡器芯片120上的至少一个第一天线接口为射频读卡器的工作天线接口；
S102，控制与工作天线接口相连的第一类天线发射第一射频信号，并接收电子标签反馈的第二射频信号；
S103，控制射频读卡器芯片处理第二射频信号。
并且，还可执行如下射频识别方法：
S201，若可移动本体100与基座200被组合，控制天线切换组件110以与天线匹配网络组件210耦合的至少一个第二天线接口为射频读卡器的工作天线接口；
S202，控制与工作天线接口相连的第二类天线发射第三射频信号，并接收电子标签反馈的第四射频信号；
S203，控制射频读卡器芯片处理第四射频信号。
使用上述射频识别方法，用户可灵活地选择射频读卡器的组合模式或分离模式，在组合模式下可读取大范围内的大量标签信息，在分离模式下手持可移动本体读取近距离范围内的标签信息，工作模式切换便捷，使用方便。
需要说明，本文中使用的术语“可移动本体”还可表示为可移动模块、可移动部件、可移动组件、移动模块、移动部件或者移动组件，等等。本申请实施例中涉及的标签可以是本领域已有的有源标签、无源标签和/或半有源标签等；本申请实施例中涉及的天线接口及天线可为符合相关标准的天线接口及天线，对天线的种类、型号等没有附加限制；本申请实施例中涉及的例如短路开关等元器件可采用已有的相关电子元器件、电路模块或功能模块，本申请实施例的实现对上述内容没有特殊要求或限制。
为了更清楚地描述本申请实施例的实现过程，图4示意性地示出了本申请一种实施例的可重构的RFID读卡器的结构示意图，其包括：固定基座和移动模块，其中，移动模块中包括RFID读卡器芯片，固定基座不包含读卡器芯片，进一步，移动模块中包括天线切换器和位置感应器，天线切换器可以将芯片引出的天线接口切换至移动模块自带的电小强极化天线，或者将芯片引出的天线接口切换至固定基座的天线接口。
具体地，移动模块中还包括微控制器、网络接口模组以及存储器等模组。其中，RFID读卡器芯片内具有射频前端模组、数字信号处理模块、时钟、电源管理模块等。固定基座中包括天线匹配网络、天线扩展器、微控制器以及电源管理模组等。
其中，位置感应器可检测判断移动模块所处位置，也就是检测移动模块与固定基座是连接(即组合模式)还是断开(即分离模式)。移动模块内的微处理器可凭借位置感应器报告的移动模块位置状态，来改变天线切换器的状态。
当读卡器移动模块放置于固定基座上时，天线切换器将天线切换到固定基座的匹配网络端口。匹配网络通过天线扩展器连接到固定基座的天线上，固定基座的天线选用全方位天线以增大读取覆盖范围。此外，固定基座的电源管理模块给移动模块供电。当移动模块与固定基座分离时，移动模块自带电源可维持其运转，天线切换器将天线切换至移动模块上的电小强极化天线，从而实现手持读卡器功能。
本申请的实施例的可重构RFID读卡器前所未有地以一颗RFID读卡器芯片实现固定与便携两种工作模式，既可节约硬件成本，也将两种独立设备化繁为简，融合为一个设备，基于该设备的射频识别方法可兼顾大范围内的多标签识别以及近距离单标签识别，最大限度地为使用者提供便捷的作业方式。
所属技术领域的技术人员可以清楚地了解到，为描述的方便和简洁，上述描述的系统、装置和单元的具体工作过程，可以参考前述方法实施例 中的对应过程，在此不再赘述。
以上所述仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本申请揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以该权利要求的保护范围为准。
