具体实施方式
下面将结合本公开实施例中的附图，对本公开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公开的部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本公开保护的范围。
取决于语境，如在此所使用的词语“如果”可以被解释成为“在……情况下”或“当……时”或“响应于确定”。
为了保证辅助生殖操作过程中信息匹配的无误性，可采用IVF核对系统。IVF核对系统可通过利用射频识别(RFID)读写设备读取培养皿上的RFID标签信息，来进行相关辅助生殖信息的匹配确认。其中，培养皿上可载有例如人类辅助生殖所需的精子、卵子或胚胎等的生物样本。如果在设定的RFID区域内发现了不属于同一对夫妇的生物样本，则IVF系统会警报提示。RFID是一种通信技术，可通过无线电讯号识别特定目标并读写相关数据，而无需在识别系统与特定目标之间建立机械或光学接触。例如，可将RFID标签贴在培养皿的底部，在将培养皿放置于读写设备水平表面上时，读写设备可读取所接触的培养皿底部的RFID标签的信息以进行核对。但是，由于RFID标签贴在培养皿的底部，通过显微镜查看培养皿所载有的生物样本时，RFID标签所贴的区域可能会产生阴影，从而影响显微镜的观察视角。并且，如果避开RFID标签的位置来放置生物样本，则培养皿的可利用面积将明显减小。
此外，在正常IVF操作流程中，几乎都要求培养皿上所载有的生物样本处于接近人体体温的特定温度下，比如36.5℃。并且，实际使用中，很多用户可能已单独购买昂贵的由金属制作或者含有金属物质的可提供更加稳定恒温系统的台面。由于金属对射频信号的干扰可能非常大，贴在培养皿底部的RFID标签可能无法在培养皿放置于含金属台面上的情况下被RFID读写设备感应到。因此，有的厂商直接在RFID读写设备中集成设置恒温模块，以保证放置在RFID读写设备表面的培养皿能处于基本恒定的温度环境中。这将使得用户无法直接利用自身已购买的具有恒温系统的台面，从而造成资源的浪费。
本公开提供一种RFID标签读取系统，能避免在器皿底部贴RFID标签带来的问题。
图1是根据本公开一示例的RFID标签读取系统的结构示意图。如图1所示，该RFID标签读取系统可包括RFID读写设备10、RFID标签11、器皿设备12。其中，所述RFID标签 11贴在所述器皿设备12的侧面，所述RFID读写设备10可与所述器皿设备12设置在同一台面上，例如水平相邻设置。所述RFID标签11可用于存储预设信息，可与所述RFID读写设备10实现射频信号的空间耦合。所述器皿设备12可用于作为所述RFID标签11的贴放载体。
当所述RFID读写设备10与贴在所述器皿设备12侧面的RFID标签11之间的距离小于或等于设定的感应距离时，所述RFID读写设备10可通过在RFID读写设备10侧面生成的且能够沿水平方向发出射频信号的感应场读取所述RFID标签11中存储的预设信息。例如，RFID标签11与RFID读写设备10之间可通过耦合元件实现射频信号的空间(无接触)耦合。在耦合通道内，可根据时序关系实现能量的传递、数据的交换等。
图4是根据本公开一示例的RFID标签读取系统的应用场景示意图。图4中示出了RFID读写设备10、RFID标签11、器皿设备12的位置关系。其中，RFID读写设备10的中间凹部位置可对着用于观察器皿设备12的显微镜的柱子40。
其中，RFID标签主要包括RFID芯片和环绕RFID芯片的金属线路、也就是RFID标签天线。RFID标签的尺寸主要是由RFID标签天线的尺寸决定的。一般来说，RFID标签天线的尺寸越大，RFID标签的感应距离越远，RFID标签的读取性能就越稳定。为了达到常见商用场景的感应距离和稳定性要求，市售的RFID标签天线的尺寸一般都在7毫米或以上，RFID标签成品的宽度都在10毫米以上。然而，IVF操作的器皿的高度一般在10毫米左右，这使得如果将宽度等于或超过10毫米的RFID标签贴在器皿设备的侧面，可能会阻碍器皿的盖子盖上，并可导致器皿无法正常使用。因此，为了能让RFID标签能够贴在IVF操作用器皿设备的侧面而不影响IVF操作用器皿设备的使用，并能够达到适合IVF台面操作所需的感应距离，本发明人通过反复测试多种RFID标签天线材料和制作工艺做出来的不同规格和形状的RFID标签天线，最后生产制作出宽约5毫米的RFID标签天线。这样，加上合成材料和RFID芯片后，可制作出宽约7mm，长约16mm的RFID标签成品。这种RFID标签的感应距离虽比当前市售的宽度在10毫米以上的常规RFID标签的感应距离略小一点，但足以满足IVF操作的需求。并且，由于RFID标签的宽度比IVF操作用器皿设备的高度小，长度也适中，可以方便地粘贴于大多数IVF器皿设备的弧形侧面并且不影响IVF操作。例如，在所述器皿设备12为高度大于或等于10毫米的培养皿的情况下，所述RFID标签11可为直径小于或等于7毫米的圆形RFID标签，或者高度小于或等于7毫米的方形RFID标签。
另外，IVF操作中除了使用10毫米或以上高度的器皿设备，还偶尔会使用到高度低于10毫米的器皿设备。例如，高度为约8毫米的器皿设备，其侧面的可粘贴区域的高度将可能只有5毫米左右。因此，为了把RFID标签贴在这种更矮的器皿设备的侧面，本发明人还通 过反复测试而研发出了宽约5mm、长约30mm的RFID标签，可以贴在几乎最矮的IVF操作用器皿设备的侧面。这种5mm宽度的RFID标签的感应距离比上述7mm宽度的RFID标签成品的感应距离要更短一些，但也能满足IVF操作的需求。
需说明的是，RFID标签11可以是可被读取信息也可被写入信息的标签，也可以是可被读取信息而不可写入信息的标签。本公开对此不加以限定，RFID标签11只要可以被读取信息即可。
此外，这里的数值只是举例说明，但本公开应不局限于此。例如，如果器皿设备12的高度为10毫米，RFID标签11的直径或高度可以为小于或等于10毫米，例如RFID标签可以是长为16毫米、高为7毫米的长方形标签。又例如，如果器皿设备12是直径35毫米、高度10毫米左右的培养皿，RFID标签11的直径或高度也最好小于或等于10毫米，例如RFID标签可以是直径为10毫米的圆形标签。
其中，所述感应距离可以是小于或等于6厘米。所述感应距离主要依赖于读写设备10侧面生成的且可沿水平方向发出射频信号的感应场。例如，所述感应距离可以是小于或等于6厘米、8厘米或10厘米等。需说明的是，随着RFID读写设备制作技术的进步，感应距离也可以增加。此外，可通过控制RFID读写设备10的感应场生成的角度和方向，让所述感应场集中到RFID读写设备10的侧面，从而可更有利于读取设置于器皿设备12侧面的RFID标签11。
其中，所述RFID读写设备10可以为高频RFID读写设备，所述RFID标签11可以为高频RFID标签。所述高频RFID读写设备10可以是高频RFID天线。
其中，RFID标签11中的预设信息可以不仅包括ID号、例如全球唯一标识ID，还可以包括预先存储在标签内EEPROM中的数据。
其中，RFID读写设备10可以如图4所示设置成凹字型。RFID读写设备10的中间凹部位置可用于对着显微镜的柱子40。RFID读写设备10的高度可以设置为10毫米左右，但不局限于此。RFID读写设备10的长和宽可以根据用户的台面或桌面的情况进行尺寸变化，例如宽度可以最小为1.5厘米，长度最小可以为10厘米。需说明的是，RFID读写设备10的形状和高度是可以改变的，只要RFID读写设备10侧面发出的射频信号基本与台面平行并可以被设置于器皿设备12侧面的RFID标签11感应到即可。
其中，所述器皿设备12载有至少一种生物样本，所述生物样本可包括人类辅助生殖所需的精子、卵子或胚胎等。所述RFID标签11可设有与所述生物样本唯一对应身份的预设信息。
其中，所述RFID读写设备10可进行了抗金属处理，从而可放置在具有恒温系统的金属台面或非金属台面上。所说的抗金属处理，可以采用任意的公知抗金属处理技术。例如，可对RFID读写设备10的表面进行处理，或采用设定的材料制作RFID读写设备10的表面等。由于RFID读写设备10是作了抗金属处理的，在金属台面上工作也不影响RFID标签11的读取效果。
图2是根据本公开一示例的RFID读写设备的结构示意图。如图2所示，该RFID标签读写设备可包括感应场生成模块21和信息读取模块22。
其中，感应场生成模块21可用于在所述RFID读写设备侧面生成沿大致水平方向发出射频信号的感应场。信息读取模块22可用于在与贴在器皿设备侧面的RFID标签之间的距离小于或等于设定的感应距离时，通过所述感应场生成模块21生成的感应场读取器皿设备侧面所贴RFID标签内的预设信息。其中，所述RFID标签与所述RFID读写设备实现射频信号的空间耦合。
一般来说，市售的RFID读写设备体积较大，放在IVF操作台面上可能会占据较大的空间而影响胚胎学家的工作。为此，本发明人通过定制使用较小的电子元器件以构建更小的感应场生成模块和信息读取模块，把RFID读写设备的整体体积大大缩小。同时，本发明人还在形状设计上根据IVF操作区域的摆放空间做了相应的调整设计，使得成型后的RFID读写设备可以摆放在IVF操作台面平常不摆放物品的区域，并且只占用台面上较小的空间，从而能够不影响胚胎学家正常使用的台面操作区域。例如，如图4所示，RFID读写设备10可被设计为具有中间凹部的大致长方形，且所述中间凹部的位置可对着置于IVF操作台面上的显微镜的柱子40。
此外，常规的RFID读写设备在侧面生成的沿大致水平方向发出的射频信号的稳定性较差，并且容易受到金属台面的干扰，从而影响感应距离和感应稳定性。为此，本发明人通过多项参数调节固化了感应场生成模块的感应场的水平发射方向，使得感应场可以相对稳定地沿着水平台面发射射频信号，从而使得RFID设备可以相对稳定地读取贴在器皿设备侧面上的RFID标签的信息。
如图2所述，为了尽量降低金属台面对RFID读写设备的发出的射频信号的稳定性的影响，RFID读写设备还可以包括抗金属模块23。这是因为，大部分的IVF操作台面均为金属材质，抗金属模块23可用于对RFID读写设备进行抗金属处理，以使得该RFID读写设备即使在金属台面上工作也不影响对RFID标签的读取效果。因此，该RFID读写设备可以在金属台面和非金属台面使用。
图3是根据本公开一示例的一种RFID标签读取方法的流程示意图。如图3所示，该标签读取方法可包括如下步骤。
在步骤301中，将RFID标签贴在器皿设备的侧面。其中，所述RFID标签存储有预设信息，所述预设信息可表示与所述器皿设备载有的生物样本对应的身份信息。并且，所述RFID标签能够与RFID读写设备实现射频信号的空间耦合。
根据一个示例，可选择直径小于或等于所述器皿设备的高度的圆形RFID标签，或选择宽度(也可称为高度)小于或等于所述器皿设备的高度的方形RFID标签，贴在所述器皿设备的侧面。
其中，所述RFID读写设备可以为高频RFID读写设备，所述RFID标签可以为高频RFID标签。此外，所述感应距离可以小于或等于6厘米、8厘米或10厘米等。需说明的是，所述感应距离可以根据技术的改进而增长。
其中，所述器皿设备可载有至少一种生物样本，所述生物样本可包括人类辅助生殖所需的精子、卵子或胚胎等。所述RFID标签中可存储有与所述器皿设备上所载有的生物样本唯一对应身份的预设信息。
在步骤302中，将器皿设备与RFID读写设备放置在同一台面上。其中，在RFID读写设备的侧面可生成能够沿大致水平方向发出射频信号的感应场。
根据一个示例，所述RFID读写设备和所述器皿设备可以放置在具有恒温系统的金属台面或非金属台面上。
在步骤303中，在所述RFID读写设备与贴在所述器皿设备侧面的RFID标签之间的距离小于或等于设定的感应距离时，通过在所述RFID读写设备侧面生成的所述感应场读取所述RFID标签内的预设信息。
通过将RFID标签贴在器皿设备的侧面，在RFID读写设备与设置于器皿设备侧面的RFID标签之间的距离小于或等于设定的感应距离时，可通过在RFID读写设备的侧面生成的感应场读取设置于器皿设备侧面的RFID标签内所存储的预设信息。这样，由于不用将RFID标签贴在器皿设备底部，可有效避免因底部贴RFID标签而影响培养器皿的实际使用面积的问题，也可避免影响观察视线的问题。而且，RFID标签贴在器皿设备的侧面，可以通过在RFID读写设备的侧面生成的感应场来读取RFID标签的预设信息，从而可免于遭受金属台面造成的信号干扰。这样，RFID读写设备和侧面贴有RFID标签的器皿设备可以直接放置在具有恒温系统的金属台面或非金属台面上，而无需RFID读写设备集成恒温模块，从而可以充分利用 已有资源。
上述装置中各个单元的功能和作用的实现过程具体详见上述方法中对应步骤的实现过程，在此不再赘述。
