为了解决传统储物设备对天线的控制混乱使得重复识别，导致天线资源的浪费的问题，在一个实施例中，如图1所示，提供了一种储物设备，包括：
箱体12，箱体12用于储存带有相应RFID标签14的物品；箱体12包括底板122；
层板124，层板124设置于箱体12的腔体内，用于分割箱体12的腔体；
多个天线16以及至少两个RFID模块18，部分天线16设置于底板122上，另一部分天线16设置于层板124上；任一天线16电连接一个RFID模块18，且各RFID模块18至少电连接一个天线16；
其中，各RFID模块18轮流通过相应的天线16进行跳频扫描，采集各RFID标签14内的物品信息。
需要说明的是，箱体用于储存带有相应RFID标签的物品。在一个示例中，箱体还包括第一侧板、第二侧板、第三侧板以及第四侧板；第一侧板、第二侧板、第三侧板和第四侧板均包括两层第一屏蔽板以及夹于两层第一屏蔽板之间的第一保温层；底板包括第二屏蔽板、ABS材料制成的透过层以及夹于第二屏蔽板与ABS材料制成的透过层之间的第二保温层；第一侧板、第二侧板、第三侧板、第四侧板和底板围成箱体的腔体。换言之，箱体的外壳(由第一侧板、第二侧板、第三侧板和第四侧板的第一屏蔽板以及底板的第二屏蔽板机械连接而成)为采用具备电磁屏蔽性能的材料制成的壳体，例如，采用金属材料制成的外壳，箱体的内壳(由第一侧板、第二侧板、第三侧板和第四侧板的第一屏蔽板以及底板的透过层机械连接而成)的四面采用具备电磁屏蔽性能的材料制成，底面采用透磁材料制成，例如，透磁材料可以采用ABS材料，在箱体的外壳与内壳之间填充保温材料形成保温层。采用电磁屏蔽的箱体可避免内部的电磁波外泄，箱体的底板采用透磁材料保证安装在底板的第一类天线发射的电磁波能够无阻碍地传播到箱体的腔体内。
在又一个示例中，储物设备还包括箱门，箱门安装在箱体上，箱门为电磁屏蔽材料制成的屏蔽门。进一步的，箱门为采用具有电磁屏蔽性能的玻璃制成的箱门。
RFID(Radio Frequency Identification，射频识别)标签是基于射频识别技术记载一定信息的电子标签，其内存储了物品的相关信息，例如单价、生产日期、保质期等等。其中，射频识别是一种非接触式的自动识别技术，通过射频信号自动识别RFID标签中的数据，或者向RFID标签写入数据，射频识别技术工作无须人工干预，可工作于各种恶劣环境。在一个示例中，RFID标签包括耦合元件以及芯片，耦合元件电连接芯片。进一步的，RFID标签为有源RFID标签、半有源RFID标签或无源RFID标签。优选的，RFID标签采用UHF(Ultra High Frequency，超高频)电子标签，对应的RFID模块采用超高频RFID模块。UHF电子标签属于无源电子RFID标签，当RFID模块在感应范围之外，UHF电子标签处于无源状态，当RFID模块在感应范围之内，UHF电子标签从RFID模块发出电磁波中提取工作所需的电源。UHF电子标签具备识别距离远、识别度高、防冲突能力强、可扩展性好的特点，使得储物设备具备良好的识别能力。
层板用于上下分割箱体的腔体，使得箱体的腔体变成多个独立的储物空间。在一个示例中，层板包括至少一个层板，层板的具体数量可根据箱体的尺寸来确定。在又一个示例中，层板为采用金属材料制成的层板，或者采用强度高的塑料材料制成的层板，需要说明的是，当层板为采用金属材料制成的层板时，天线贴附在层板上，当层板采用强度高的塑料材料制成的层板(例如，层板为ABS材料制成的层板)时，天线可贴附在层板上也可嵌入层板内。进一步的，层板为网格状层板或镂空层板。在再一个示例中，储物设备还包括多个隔板， 隔板设置在层板上，具体而言，各层板上均设置有至少一个隔板，隔板用于将层板上的空间进行水平分割。进一步的，隔板为网格状隔板，可采用金属隔板或塑料隔板。
天线是RFID标签与RFID模块之间收发信号媒介。可通过以下参数来表征天线的性能：增益、带宽、输入阻抗、反射系统、电压驻波比、入射功率/反射功率、波瓣宽度、前后比以及极化特征，其中，增益是用来衡量天线朝一个特定方向收发信号的能力；带宽是指谐振点附近一定范围内频率；输入阻抗是指天线输入端信号电压与信号电流之比；反射系数是指反射电压与入射电压的比值；电压驻波比是指波腹电压与波节电压的比值；波瓣宽度是指主瓣最大辐射方向两侧；辐射强度降低3dB的两点之间的夹角，用于描述天线辐射能量在主瓣方向的集中程度，需要说明的是，波瓣宽度越大，箱体内需要设置的天线的数量越少，有利于降低储物设备的制造成本；前后比是指主瓣与后瓣的最大辐射强度的比值；极化特征表示天线发出的电磁波传播的方式，包括线极化、圆极化以及椭圆极化。
在一个示例中，天线为线极化天线。相应的，RFID标签采用线极化标签，在实际使用过程中，为了使得天线读写效率最大化，需要保证线极化天线的极化方向与RFID标签的极化方向一致。
在又一个实施例中，天线为圆极化天线。相应的，RFID标签采用圆极化标签，进一步的，圆极化天线可为左旋圆极化天线或右旋圆极化天线。具体的，圆极化天线产生的圆极化波是等幅旋转场，可分解为两正交等幅、相位相差90度的线极化波，即无论收信号的天线的极化方向如何，接收到的信号都是相同的，采用圆极化天线方式，使得RFID模块对天线的方位以及标签的方位的敏感 性降低。
进一步的，在实际应用过程中，天线的数量可根据箱体的尺寸而定，当箱体的尺寸小则设置较少数量的类天线，当箱体的尺寸大则设置较大的数量的天线。其中，部分天线设置在底板上，另一部分天线设置在层板上，进一步的，天线为单向辐射天线或双向辐射天线，需要说明的是，如图2所示，天线的辐射方向设置朝向物品携带的RFID标签，使得天线的效率最大化。具体的，设置在底板上的天线采用单向辐射天线，且天线的辐射方向朝向底板上的物品携带的RFID标签。设置在层板上的天线可采用单向辐射天线也可采用双向辐射天线，当天线为单向辐射天线时，天线辐射的方向朝向层板上的物品携带的RFID标签；当天线为双向辐射天线时，天线辐射的一个方向朝向层板上的物品携带的RFID标签，天线辐射的另一个方向朝向底板上的物品携带的RFID标签。
进一步的，在实际应用过程中，天线的数量可根据箱体的尺寸而定，当箱体的尺寸小则设置较少数量的天线，当箱体的尺寸大则设置较大的数量的天线，例如，在一个箱体内设置10个天线，其中2个天线设置在底板上，8个天线设置在层板上。根据箱体的尺寸设置适当数量的第二类天线能够使天线的读取效率最大化、减少重复读取的时间。
RFID模块相当于天线的收发机，能够通过天线读取RFID标签内的信息，也能通过天线向RFID标签写入信息。在一个示例中，RFID模块为多通道RFID模块，可通过连接多个天线，增强了储物设备的扩展性，即随着箱体的尺寸变大，可相应地增加天线的数量，从而保证大尺寸的箱体能被天线辐射范围全面覆盖，降低识别盲区，改善识别效果。
各RFID模块分别电连接一部分天线，各天线不重复电连接RFID模块，一 个天线只电连接一个RFID模块。
储物设备具体的工作过程为：各个RFID模块可以轮流在外部控制信号的触发下，例如运维人员手动触发提供的控制信号或者上位机输出的控制信号，开始进入工作状态，依次驱动自身所连接的各天线进行跳频扫描，以采集射频信号覆盖范围内的各RFID标签所附物品的物品信息。例如在任一个RFID模块工作时，其他RFID模块保持待机。该工作状态的RFID模块20先驱动所连接的任一天线在预设频段内，例如920MHz(兆赫兹)到925MHz频段内进行跳频扫描后，再驱动另一天线在前述预设频段内进行跳频扫描，如此依次驱动各个天线18进行跳频扫描直到遍历该RFID模块上所连接的所有天线。在该RFID模块遍历其上各个天线扫频后，下一个RFID模块开始进入工作状态，工作模式与前一工作结束后的RFID模块相同。
为了便于理解储物设备工作过程，现举例说明：
在一个示例中，包括10个天线，分别标为1号、2号、3号至10号，其中，1号至8号天线设置在层板上，9号天线和10天线设置在底板上。包括2个RFID模块，分别标为第一RFID模块和第二RFID模块。标号为奇数的天线电连接第一RFID模块，标号为偶数的天线电连接第二RFID模块。在工作过程中，第一RFID模块依次分别通过1号、3号至9号天线在预设频段内扫描读取RFID标签内的信息，在第一RFID模块完成工作后，第二RFID模块再依次分别通过2号、4号至10号天线在预设频段内扫描读取RFID标签内的信息，在第二RFID模块完成工作后再返回到第一RFID模块工作，依次轮流循环。该示例仅仅说明各RFID模块依次轮流通过对应的天线在预设频段内扫描读取RFID标签内的信息的工作方式，并不构成对RFID模块的数量、天线的数量、各RFID模块的工 作顺序以及天线的工作顺序的限定。进一步的，预设频段可根据实际需要而定，例如，预设频段为920MHz至925MHz。
本申请储物设备各实施例中，储物设备包括箱体、层板、多个天线以及至少两个RFID模块，其中，箱体用于储存带有相应RFID标签的物品，箱体包括底板；层板设置于箱体的腔体内，用于分割箱体的腔体；部分天线设置于底板上，另一部分设置于层板上；任一天线电连接一个RFID模块，且各RFID模块至少电连接一个天线；储物设备具体过程为：各RFID模块轮流通过相应的天线进行跳频扫描，采集各RFID标签内的物品信息，即一个RFID模块控制一部分天线，在一个RFID模块完成对所有与其连接的天线的控制后，下一个RFID模块才进入工作状态，从而实现有次序的控制储物设备中的天线，避免了天线控制混乱的问题，进而有效地利用了天线资源。
在一个实施例中，如图3所示，提供了一种储物设备控制方法，包括以下步骤：
步骤S310，若当前工作状态的RFID模块相应的天线跳频扫描结束，则向下一个RFID模块发送控制信号，以使下一个RFID模块通过相应的天线进行跳频扫描，采集各RFID标签内的物品信息。
其中，可采用控制器、上位机、终端等具备控制功能的设备来对RFID模块进行控制，并不限定RFID模块的控制方为何种设备或者何种方式的控制，只要实现对RFID模块的控制即可。
具体的，在当前处于工作状态的一个RFID模块工作结束，也即该工作状态的RFID模块已经依次驱动其上所有天线进行了跳频扫描时，可以通过上位机或者储物装置自带的控制系统，例如冰柜的总控制器向下一个RFID模块发送控制 信号，控制信号可以是但不限于时序电平信号。下一个RFID模块开始在设定频段上，依次驱动其上各天线进行了跳频扫描。下一个RFID模块开始工作时，驱动其上任一天线在920MHz到925MHz频段内进行跳频扫描。待该天线扫频接收，即驱动下一天线在920MHz到925MHz频段内进行跳频扫描，如此，直至该下一个RFID模块上的各个天线均完成跳频扫描即结束该下一个RFID模块的工作。如此轮流控制各个RFID模块进出工作状态，即可实时通过各天线跳频扫描时，各物品上RFID标签反馈的射频信号读取各物品的物品信息。
需要说明的是，储物设备控制方法是基于储物设备的硬件结构而实现的方法。
为了便于理解储物设备控制方法的具体流程，现举例说明：
在一个示例中，包括12个天线，分别标为1号、2号、3号至12号，其中，1号至10号天线设置在层板上，11号天线和12天线设置在底板上。包括3个RFID模块，分别标为第一RFID模块、第二RFID模块以及第三RFID模块。1号至4号天线电连接第一RFID模块，5号至8号天线电连接第二RFID模块，9号至12号天线电连接第二RFID模块。在具体的控制流程中，第一RFID模块依次分别通过1号至4号天线在预设频段内扫描读取RFID标签内的信息，在第一RFID模块完成工作后，第二RFID模块再依次分别通过5号至8号天线在预设频段内扫描读取RFID标签内的信息，在第二RFID模块完成工作后，第三RFID模块再依次分别通过9号至12号天线在预设频段内扫描读取RFID标签内的信息，在第三RFID模块完成工作后再返回第一RFID模块工作，依次轮流循环。该示例仅仅说明各RFID模块依次轮流通过对应的天线在预设频段内扫描读取RFID标签内的信息的工作方式，并不构成对RFID模块的数量、天线的数量、 各RFID模块的工作顺序以及天线的工作顺序的限定。
本申请储物设备控制方法各实施例中，能够合理地控制RIFD读写模块按照次序的工作，再由RIFD读写模块各自通过与其连接的天线进行扫描读取，避免了天线控制混乱的问题，也避免了重复识别的问题，进而提高了天线识别效率，有效地节省了天线资源。
应该理解的是，虽然图3的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，这些步骤可以以其它的顺序执行。而且，图3中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，这些子步骤或者阶段的执行顺序也不必然是依次进行，而是可以与其它步骤或者其它步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
在一个实施例中，如图4所示，提供了一种储物设备控制装置，包括：

压缩机52机械连接冷凝管54；冷凝管54设置于储物设备的箱体12内。
其中，冷藏设备用于以低温保存食物、药品等物品的电气设备。例如，冷藏设备包括冰柜、冰箱、冷冻库等等。冷凝管设置在箱体的内壁上。
在一个示例中，冷藏设备还包括照明设备，照明设备。具体的，照明设备不会产生电磁波外泄，避免外泄的电磁波干扰RFID模块通过天线读取RFID标签上的信息。冷藏设备避免在安装冷凝管的位置设置天线，从而避免冷凝管上的结霜现象破坏天线。
在又一个示例中，冷藏设备还包括控制器，控制器电连接RFID模块、压缩机以及照明设备。控制器为冷藏设备的控制中心，用于控制冷藏设备的各部分的协调工作。
本申请冷藏设备各实施例中，通过将天线设置在箱体的底板和层板上，有效克服解决了传统冷藏设备的箱体内部天线覆盖范围不够、箱体内冷凝结霜对天线的干扰、箱体金属内壁以及箱体内部金属支架引起的天线信号衰减等问题，并且通过合理地设置天线有效地减少了识别盲区，提高RFID模块对标签识别的可靠性，最终解决了长久以来大容量卧式冷藏设备布置天线的难题。
在一个实施例中，如图6所示，提供了一种冷藏系统，包括管理设备62、设备接口64以及多个如上所述的冷藏设备；
