交叉引用
本申请引用于2017年08月04日递交的名称为“天线检测装置、系统及方法”的第201710662566.4号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请涉及检测技术领域，尤其涉及一种天线检测装置、系统及方法。
背景技术
NFC(Near Field Communication，近距离无线通讯技术)是一种短距高频的无线电技术，它是由非接触式射频识别(RFID，Radio Frequency Identification)和互联互通技术整合演变而来，工作频率在13.56MHz，可以在移动设备、消费类电子产品、PC(personal computer，个人计算机)和智能控件工具间进行近距离无线通信。
现有的产线上检测NFC天线性能的方法一般是通过天线检测工装进行。方法是：预先在PCB(Printed Circuit Board，印刷电路板)上模拟出天线所处的环境，并根据需要留有一定数量pin针，在PCB板上焊接cable线(线缆)，cable内芯和pin针连接将矢网信号馈入，待测天线产品放入下压块的槽内，天线的pad(焊接)点和pin针接触，然后把上压块压下，使pad点和pin针充分接触，从矢网处可以看到待测天线的波形，和预先根据实际工作频段在PCB板上调试出来的波形对比，如果天线断裂或者尺寸变化则波形会发生频偏，从而也就可以知道天线性能是否正常。但是这种检测方法存在以下几点缺陷：
1、生产成本比较大。每一台检测装置都需要有矢网，夹具，PCB板，上、下压块，cable线，欧姆表等，其中上压块时间长了会有磨损，导致产品定位不准；pin针长时间的受压，易磨损，导致接触不良；另外还需要通过cable线，借助矢网看天线的波形，频繁地拆装cable会导线内芯宽松，接触不良，这些均需要定期更换；再加上还需用欧姆表检测天线的电阻值，计算 其Q(品质因数)是否在标准天线的波动区间内；此外矢网的价格也比较昂贵。
2、程序繁琐，检测时间较长。因传统的检测方法对前期的准备工作要求比较高，并且工作量也比较大，前期的准备工作的精确性直接影响到产品的品质。在检测之前一方面需要在跟实际天线环境相近的PCB板上调试出与整机相似的谐振，并且敏感度要求一致；另一方面还需考虑到生产方面，调试的波形要平滑便于产线生产管控；并且在检测过程中，还需用欧姆表测天线的电阻值。
3、准确度有待提高。首先在与实际天线环境相近的PCB板上调试的波形与整机波形有些许偏差，因为两者的环境不可能完全相同，再加上还需要考虑利于生产上的管控；另外待测天线的波形和与实际天线环境相近的PCB板上调试出来的波形也有一定的偏差，所以这样双重的偏差会导致误差加大，从而也就影响了准确度。
基于以上几个方面的分析，现有的检测系统中存在检测成本大；程序繁琐，检测时间长；检测的准确度不高等问题。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
在本申请的说明书、权利要求书及上述附图中描述的一些流程中，包含了按照特定顺序出现的多个操作，这些操作可以不按照其在本文中出现的顺序来执行或并行执行。操作的序号如101、102等，仅仅是用于区分各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的消息、设备、模块等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请提供一种用于天线检测的新方案，基于非接触式射频识别(RFID，Radio Frequency Identification)技术实现。对于天线检测装置而言，由于连接有待测天线的射频标签和读写器的工作频段相同，仅检验作为射频标签状态下性能即可反应待测天线的性能好坏。若读写器能与连接有待测天线的射频标签成功建立无线连接，则认为待测天线合格；若读写器与连接有待测天线的射频标签无线连接建立失败，则认为待测天线不合格。出于上述天线检测思路，发明人设计了如下天线检测装置。
图1和图2示出了本申请一实施例提供的天线检测装置的结构示意图。如图1所示，所述天线检测装置包括：射频标签1、电连接件2以及读写器3。其中，电连接件2设置在射频标签1上；射频标签1通过电连接件2连接待测天线4；读写器3与待测天线4相距预设检测距离D。读写器3被设置为通过待测天线4对射频标签1进行寻卡操作，若通过寻卡操作与射频标签1成功建立无线连接，则确定待测天线4合格；若通过寻卡操作与射频标签1建立无线连接失败，则确定待测天线4不合格。
采用本申请实施例提供的技术方案，将待测天线通过电连接件与射频标签连接，只需通过读写器对射频标签进行寻卡操作的结果即可检测出待测天 线是否合格，整个检测过程简单，不需要现有技术中的诸多复杂操作；另外，本申请实施例提供的技术方案只需读写器和连接有待测天线的射频标签工作在相同频段，测试过程不存在现有技术中整机波形以及与实际天线环境相近的PCB板上调试的波形偏差等因素的干扰，因此检测准确度高。
这里需要补充的是：上述提及的预设检测距离为天线最差性能下的距离。因为NFC(Near Field Communication，近场通信)天线有多种规格，不同规格的NFC天线其对应的天线最差性能下的距离也不同。此处的预设检测距离可根据待测天线的规格不同适应性的变化。
进一步的，如图2和3所示，上述实施例提供的天线检测装置还可包括检测台5。检测台5上设有容置槽；待测天线4放置在容置槽内。此时读写器3与检测台5的容置槽内的待测天线4相距预设检测距离D。
进一步的，可以将射频标签1设置在检测台5的下方；电连接件2贯穿检测台5伸入容置槽内(图2中未示出)，以在待测天线4放置于容置槽内时待测天线4通过电连接件2与射频标签1连接；读写器3与检测台5的容置槽内的待测天线4相距预设检测距离D。
需要说明的是，射频标签1还可以设置在其他位置，例如将射频标签1设置在检测台5上，电连接件2直接与容置槽内的待测天线4连接。本申请实施例中，只需保证电连接件2与待测天线4连接，对射频标签1的放置位置不做限定。
一种可实现的技术方案，上述检测台可采用如图2和3所示的结构实现。检测台5包括：下压块51及上压块52；下压块51的上表面设有容置槽；电连接件2伸入容置槽内，以便与待测天线4连接；上压块52覆盖在下压块51的上表面。
其中，可使用固定件(例如螺钉)将下压块51固定。检测人员或送料机将待测天线4放置在容置槽并保证待测天线4与电连接件2充分接触或连接后，将上压块52覆盖在下压块51上以确保待测天线4不发生移动。
进一步的，如图2所示，可以将射频标签设置在下压块51的下方；此时电连接件2贯穿下压块51伸入容置槽内。
当然，射频标签1也可以设置在下压块51的容置槽的一侧，并将电连接件2置于下压块的上表面，待测天线4与电连接件2连接。本申请对射频标 签放置位置不做限制。
需要说明的是，下压块51的上表面是指与上压块52接触的表面。
进一步的，如图3所示，上压板52与下压板51可铰接，以使上压板52能相对下压板51转动。上压板52的第一侧边521与下压板51的相对侧边铰接；上压板52的第二侧边522上设有拨块523。其中，第一侧边521与第二侧边522为相对的两个侧边。
在一种可实现的技术方案中，如图2所示，天线检测装置还可包括：至少两个支撑架8。读写器3设置在检测台5的下方，至少两个支撑架8设置在检测台5的下方，至少两个支撑架8的顶端与检测台5连接以支撑检测台5，使得检测台5的容置槽内的待测天线4处于读写器3上方的预设检测距离D的高度。在具体实施时，可选用固定长度的支撑杆，或者可伸缩杆作为支撑架8。选用可伸缩杆作为支撑架8，检测人员可根据检测需求调节可伸缩杆的长度，进而改变读写器3与检测台5的容置槽内的待测天线4之间的距离。
或者，如图2所示，本实施例提供的天线检测装置还可包括：支撑台7。读写器3设置在支撑台7上。至少两个支撑架8中的每个支撑架8上均设置有用于承载支撑台7的搭接板81；支撑台7的边缘搭接在搭接板81上。每个支撑架8上设置的搭接板81可以为一个或多个，本申请实施例对此不作具体限定。可选地，每个支撑架8上均设置有一个搭接板81时，该搭接板81可与支撑架8为可拆卸连接；用户通过调节搭接板81的位置来改变搭接在搭接板81上的支撑台7与检测台5之间的距离。当每个支撑架8上均设有两个或两个以上的搭接板81时，两个或两个以上的搭接板81沿支撑架8的高度方向排布，且两相邻搭接板81具有设定间隙，该设定间隙大于支撑台7的厚度，以能容置所述支撑台7。使用时，可通过将支撑台7搭接在不同高度的搭接板81的方式来调整支撑台7与检测台5的距离。
进一步的，上述内容中提及的电连接件2可以为弹片或探针，本申请实施例对此不作具体限定。
图4示出了本申请一实施例提供的天线检测系统的结构示意图。如图4所示，天线检测系统包括：天线检测装置及检测控制器32。其中，检测控制器32与天线检测装置中的读写器3连接。天线检测装置包括：射频标签1、电连接件2以及读写器3。电连接件2设置在射频标签1上；射频标签1通 过电连接件2连接待测天线4；读写器3与待测天线4相距预设检测距离D；读写器3通过待测天线4对射频标签1进行寻卡操作，若通过寻卡操作与射频标签1成功建立无线连接，则确定待测天线4合格；若通过寻卡操作与射频标签1建立无线连接失败，则确定待测天线4不合格。检测控制器32被配置为向读写器3发送寻卡指令，以使读写器3在接收到寻卡指令后对射频标签1进行寻卡操作。
采用本申请实施例提供的技术方案，将待测天线通过电连接件与射频标签连接，只需通过读写器对射频标签进行寻卡操作的结果即可检测出待测天线是否合格，整个检测过程简单，不需要现有技术中的诸多复杂操作；另外，本申请实施例提供的技术方案只需读写器和连接有待测天线的射频标签工作在相同频段，测试过程不存在现有技术中整机波形以及与实际天线环境相近的PCB板上调试的波形偏差等因素的干扰，因此检测准确度高。
进一步的，如图4所示，上述提供的天线检测装置还可包括：显示器34。检测控制器32还被配置为接收读卡器3反馈的寻卡操作结果；显示器34与检测控制器32连接，被配置为显示所述检测控制器32接收的寻卡操作结果。
这里需要补充的是：上述检测控制器32可选用现有的计算机，比如，台式计算机或笔记本电脑来实现。当检测控制器选用计算机实现时，上述实施例提供的天线检测装置可无需再增设显示器，直接复用计算机上的显示屏即可对寻卡操作结果进行显示。
上述实施例中，读写器3利用数据线通过通信接口33(如USB接口)实现与检测控制器32的连接(如图4所示)；或者读写器3利用无线通信功能模块实现与检测控制器32的无线通信连接；等等，本申请实施例对此不作具体限定。
图5示出了本申请另一实施例提供的天线检测系统的结构示意图。本实施例选用计算机作为检测控制器，并复用计算机的显示器对检测控制器输出的检测结果进行显示。如图5所示，天线检测装置包括：检测台5、射频标签1、读写器3及计算机6。其中，检测台5上设有用于放置待测天线4的容置槽；射频标签1上设有电连接件(图中未示出)。射频标签1设置在检测台5的下方，电连接件贯穿检测台5伸入容置槽内，以在待测天线4放置于容置槽内时待测天线4通过电连接件与射频标签1连接。读写器3通过通信 接口33(如USB接口)与计算机6连接。读写器3布置在与检测台5相距预设检测距离D的位置处。计算机6被配置为向读写器3发送寻卡指令，并根据读写器3按照寻卡指令对射频标签1进行寻卡操作后反馈的是否与射频标签1成功建立无线连接的信息，确定待测天线4是否合格。
这里需要说明的是，上述计算机配置的：“向读写器3发送寻卡指令，并根据读写器3按照寻卡指令对射频标签1进行寻卡操作后反馈的是否与射频标签1成功建立无线连接的信息，确定待测天线4是否正常”，可由安装在计算机上的检测软件来实现；或者是由集成在计算机上的一个具有嵌入式程序的硬件。另外，上述提及的通信接口可选用USB接口实现，本申请实施例对此不作具体限定。
这里需要补充的是：通过连接通信接口的数据线实现读写器3与计算机6的连接，一方面计算机可通过通信接口为读写器3提供5V的工作电压；另一方面用于实现读写器3与计算机6之间的数据通信。
上述各实施例中涉及的读写器与射频标签的工作频率相同，例如，读写器与射频标签的工作频率均为13.56MHz。读写器与射频标签之间的预设检测距离可以是天线最差性能下的距离。
上述实施例提供的天线检测装置的检测过程如下：
在读写器的工作范围内，连接有待测天线的射频标签放置在距读写器预设检测距离的位置处。此预设检测距离是天线性能最差情况下的距离。在此预设检测距离下读写器和连接有待测天线的射频标签若未能建立无线连接，此时显示器上会显示没有发现卡(如图6所示)，表明待测天线不合格。若读写器和连接有待测天线的射频标签能建立无线连接，则显示器上会显示执行成功(如图6所示)，表明待测天线合格，能满足生产品质的要求。
图7示出了本申请一实施例提供的天线检测方法的流程示意图。本实施例提供的天线检测方法的执行主体为：读写器(即上述天线检测装置中包含的读写器)。本实施例提供的天线检测方法应用于上述实施例提供的天线检测装置。如图7所示，所述方法包括：
101、通过待测天线对射频标签进行寻卡操作，其中，所述射频标签通过电连接件与所述待测天线连接。
102、若通过所述寻卡操作与所述射频标签成功建立无线连接，则确定所 述待测天线合格。
103、若通过所述寻卡操作与所述射频标签建立无线连接失败，则确定所述待测天线不合格。
采用本申请实施例提供的技术方案，将待测天线通过电连接件与射频标签连接，只需通过读写器对射频标签进行寻卡操作的结果即可检测出待测天线是否合格，整个检测过程简单，不需要现有技术中的诸多复杂操作；另外，本申请实施例提供的技术方案只需读写器和连接有待测天线的射频标签工作在相同频段，测试过程不存在现有技术中整机波形以及与实际天线环境相近的PCB板上调试的波形偏差等因素的干扰，因此检测准确度高。
这里需要说明的是；本实施例提供的天线检测方法是基于上述天线检测装置实现的；本方法实施例的内容与上述天线检测装置实施例中的内容可相互补充参照。
上述步骤101可采用如下方法实现：通过所述待测天线向所述射频标签发送无线连接建立请求消息；若接收到所述射频标签反馈的连接响应消息，则与所述射频标签成功建立无线连接；若未接收到所述射频标签反馈的连接响应消息，则与所述射频标签建立无线连接失败。
具体实施时，上述读写器通过待测天线向射频标签发送的无线连接建立请求消息，例如可以是Request all命令或Requeststd命令；射频标签反馈的连接响应消息，例如可以是射频标签Block 0中的类型TagType号信息。
与现有技术相比，本申请的优势在于：
1、本申请实施例提供一种天线检测新方案，具有操作简便的优点，可以说是傻瓜式操作。本申请实施例提供的技术方案不需要事先根据实际天线环境相近的PCB板上调试出与整机谐振相似并且敏感度一致的波形，只需根据是否满足在天线最差性能下建立通信，如果在此天线性能最差的距离下能够建立通信，则此天线性能合格，否则视为不合格。
2、采用本申请实施例提供的技术方案，检测准确度较高。因为本申请实施例提供的技术方案没有整机波形以及与实际天线环境相近的PCB板上调试的波形的偏差，也没有待测天线的波形和实际天线环境相近的PCB板上调试出来的波形的偏差，这两种偏差均不存在，而只依据读写器和连接有待测天线的射频标签在一定距离下能否建立正常通信。
3、采用本申请实施例提供的技术方案，生产成本较低。每一台天线检测装置只需要一台设有电连接件的射频标签及读写器，其中读写器基于现有读写操作过程对待测天线进行检测，且检测结果一目了然，而没有传统检测方法中的矢网，欧姆表等昂贵的仪器。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到各实施方式可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件。基于这样的理解，上述技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在计算机可读存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行各个实施例或者实施例的某些部分所述的方法。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
