<RFID标签>
在一些实施例中，为了实现对食材的智能管理，使用RFID标签对储藏室中的食材进行标识，具体的，预先获取RFID标签的标识信息，如RFID标签中写入的标签编码，建立RFID标签的标识信息与指定的食材信息的对应关系，实现RFID标签与食材的关联；在食材上贴设RFID标签后将食材放入到冰箱中，冰箱通过检测RFID标签的信号获取RFID标签的标识信息，在获取到标识信息的情况下，通过预先建立的RFID标签的标识信息与食材信息的唯一对应关系，即可确定RFID标签对应的食材信息，并通过将食材信息显示在用户界面中，使得用户通过用户界面获知冰箱中的食材，并可通过操作用户界面对食材执行管理操作。
在一些实施例中，在每个储藏室内设置RFID检测模块，RFID检测模块用于在相应的储藏室发射无线信号并接收该储藏室内的RFID标签的信号，以获取RFID标签的标识信息。在一些实施例中，RFID检测模块具体可以为天线。不同的储藏室内设置的天线的功率可以不同。各个储藏室的天线的功率能够保证天线识别到自身间室包括的食材即可，从而避免功率太大时会增加误识别率，功率太小时会识别不全自身间室的食材。在具体的实现中，可以预先根据各个储藏室的空间大小确定天线的功率，并在冰箱中设置各个天线的功率，空间越大，功率越大。在一些实施例中，冰箱还可以包括RFID处理模块，RFID处理模块分别与每个RFID检测模块连接，用于控制RFID检测模块发射无线信号以及接收RFID检测模块反馈的RFID标签的信号。在一些实施例中，控制器与RFID检测模块连接，控制RFID检测模块识别储藏室内RFID标签的信号，获取每个RFID标签的标识信息和对应的食材信息。由于RFID检测模块检测范围很大，导致无法准确判断每个RFID标签的存放位置，例如，冷冻室内的天线可能会识别到其他储藏室的RFID标签，进而无法实现对食材的智能分区管理，影响用户体验。
在一些实施例中，若检测到冰箱中出现新增RFID标签，将新增RFID标签对应的食材信息显示在指定用户界面中，用户通过操作指定用户界面，选择要分区的食材和对应的储藏室，从而实现对新增食材的智能分区管理。在一些实施例中，控制器被配置为：根据储藏室内每个RFID标签对应的食材信息绘制用户界面，并在显示屏上显示出来，如食材管理界面。在食材管理界面中，冰箱中的食材以食材图标、图文等形式尽数展示。此外，还可以在用户界面中绘制功能控件，如RFID标签识别控件、食材添加控件等。
在一些实施例中，食材管理界面可以包括多个食材展示区和功能控件，一个食材展示区可以对应一种食材类别或者一个储藏室，每个食材展示区用于显示冰箱中RFID标签对应的食材信息。其中，在食材类别对应的食材展示区中显示相应类别的食材信息，在储藏室 对应的食材展示区中显示相应储藏室中的食材的食材信息。食材管理界面中显示的食材信息包括但不限于食材图标、食材名称、食材的新鲜度标识，其中，食材图标可以根据食材的象形图片生成，食材的新鲜度标识用于示出食材的放入时间、距离过期的剩余时间和过期时间中的任意一项或者多项。食材管理界面中的功能控件包括但不限于用于触发RFID标签识别的控件、用于添加食材信息的控件以及用于显示菜谱信息的控件等。
图3为根据本申请一个或多个实施例的食材管理界面，参阅图3，该食材管理界面被分割成左右两个显示区域；其中，左侧区域包括RFID标签识别控件和与各个食材类别对应的食材展示区，如水果类、蔬菜类，每个食材展示区中显示有相应类别的食材图标和食材名称；右侧区域包括推荐菜谱控件和与各个储藏室对应的食材展示区，如冷藏室、变温室、冷冻室等，每个食材展示区中显示有相应的食材图标和食材名称。在一些实施例中，在图3所示的食材管理界面的右侧区域还包括自定义区，该自定义区用于展示冰箱中用户未对其进行分区归类的新增食材。在图3所示的食材管理界面中，冰箱内通过RFID标签所标识的食材尽数得到展示。
<RFID标签与食材信息对应关系>
在一些实施例中，通过建立RFID标签与食材信息之间的对应关系，实现RFID标签与食材信息之间的虚拟关联，而无需针对每个RFID标签执行写入食材信息的操作，且可以通过修改RFID标签与食材信息之间的对应关系，使得同一个RFID标签先后与不同的食材信息相对应，提高RFID标签的使用灵活性。需要说明的是，建立RFID标签与食材信息之间的对应关系的方式有多种，以下将给出几种具体实现方式。
在一些实施例中，预先建立RFID标签的标识信息与食材信息的对应关系，实现RFID标签与食材的虚拟关联。其中，RFID标签的标识信息可以为检测模块识别到的RFID标签的标签编码，也可以是标签编码中的一个码段。在这些实施例中，冰箱控制器根据每个RFID标签的标识信息和预先建立的对应关系确定每个RFID标签对应的食材信息。示例性的，预先建立的RFID标签的标识信息与食材信息的对应关系可以如下表1所示：
表1
RFID 食材信息
标识1 苹果、水果类
标识2 黄瓜、蔬菜类
标识3 猪肉、肉类
…… ……
在上述实施例中，通过建立RFID标签的标识信息与食材信息的对应关系，实现RFID标签与食材的虚拟关联，无需针对每个RFID标签进行信息写入操作，只需要在获取到RFID标签的标识信息后，将标识信息与指定的食材信息对应保存在数据库中即可。并且，可以通过修改该对应关系使同一RFID标签先后与不同的食材关联，解决食材信息一旦写入将无法更改的问题，提高对RFID标签的使用灵活性。
在一些实施例中，在服务器侧建立RFID标签的标识信息与食材信息的对应关系表并发布。在冰箱侧，由控制器从服务器获取该对应关系表并保存在本地；当需要在用户界面中显示冰箱内通过RFID标签标识的食材时，控制器指示RFID检测模块检测冰箱内RFID标签的信息以获取RFID标签的标签编码，并从标签编码中解析出RFID标签的标识信息，再根 据本地保存的对应关系表确定与RFID标签的标识信息对应的食材信息，最后根据与RFID标签对应的食材信息显示用户界面。
手动录入食材
在一些实施例中，在冰箱侧建立RFID标签的标识信息与食材信息的对应关系表并保存在本地。具体的，在显示屏上显示食材管理界面时，用户可以通过操作食材管理界面输入指示进行食材信息录入的指令，例如，用户点击食材管理界面提供的食材信息录入控件以指示进行食材信息录入；当控制器接收到该指令后，开始检测放置在指定区域的RFID标签的信号以获取RFID标签的标识信息，并显示用于将RFID标签与食材信息进行关联的关联界面，关联界面中显示有获取到的RFID标签的标识信息，关联界面被配置为可以接收用户输入的食材信息，其可以包括用于输入食材信息的输入位置；当控制器接收到用户在关联界面输入的食材信息后，将接收到的食材信息与标识信息对应保存，从而，完成并完善RFID标签的标识信息与食材信息的对应关系表的建立。
图4A-4C为根据本申请一个或多个实施例的食材录入界面，接着如图3所示，用户可以点击该界面中的RFID标签识别控件以输入指示进行食材信息录入的指令。当控制器接收到用户输入的该指令后，响应于该指令，在如图3所示的食材管理界面的上层显示用于提示用户将RFID标签放置在感应区域的提示(如图4A所示)并开始检测放置在感应区域的RFID标签的信号以获取RFID标签的标识信息。在控制器获取到RFID标签的标识信息后，在显示屏上呈现包含标识信息的关联界面。图4B为本申请根据示例性实施例示出的一种关联界面，如图4B所示，该关联界面显示有RFID标签的标识信息“20200005”、用于输入食材名称的输入位置、用于输入食材类别的输入位置以及“取消”控件和“确定”控件。
在上述一个或多个实施例中，通过RFID模块识别RFID标签的标识信息并显示在关联界面中，无需用户手动输入该标识信息，从而避免输入错误，节省用户操作。通过建立RFID标签与食材信息之间的对应关系，实现RFID标签与食材信息之间的虚拟关联，而无需针对每个RFID标签执行写入食材信息的操作，且可以通过修改RFID标签与食材信息之间的对应关系，使得同一个RFID标签先后与不同的食材信息相对应，提高RFID标签的使用灵活性。

在一些实施例中，RFID标签的标签编码包括至少两个码段，分别为第一码段和第二码段。其中，第一码段用于写入第一编码，该第一编码可以是预定编码或者是非预定编码。对于第一编码为预定编码的RFID标签，其对应的食材信息可由用户自定义；对于第一编码为非预定编码的RFID标签，其对应的预设食材信息被预先保存在云端服务器中，不可由用户自定义。第二码段用于写入第二编码，该第二编码为RFID标签的唯一性标识信息。在一些实施例中，RFID标签的标签编码包括的至少两个码段符合预设组成规则，控制器在获取到标签编码后，根据该预设组成规则截取第一码段和/或第二码段等以获取到第一编码和/或第二编码，从而节省了解析长编码信息的过程，提高处理效率。
在一些实施例中，预定编码具有唯一性，如00；非预定编码不具有唯一性，其可以有多个，一个非预定编码对应于一种食材信息。示例性的，一种RFID标签的标签编码结构如下表2所示：
表2
Figure PCTCN2021103101-appb-000001
例如，控制器获取到RFID标签的标签编码为“01123456789012345678901234”，则根据预设组成规则，可以截取到第一编码为“01”，截取到第二编码为“123456789012345678901234”。需要说明的是，根据不同的需求，RFID标签的标签编码还可以包括更多码段，如第三码段，用于写入RFID标签的厂家标识，再如第四码段，用于作为标签编码的保留位，以提高RFID标签的可扩展性。
在一些实施例中，RFID标签的厂家标识也可以包含在第二码段中，此处不予赘述。示例性的，第一编码(非预定编码)与食材信息的对应关系可如下表3所示：
表3
RFID第一编码 食材名称 食材类别
01 萝卜 蔬菜类
02 胡萝卜 蔬菜类
03 莲藕 蔬菜类
…… …… ……
在一些实施例中，控制器被配置为：响应于用户输入的指示对RFID标签进行识别的指令，获取RFID标签的标签编码；然后判断第一编码是否为预定编码；若第一编码是预定编码，则显示第一关联界面，该第一关联界面被配置为可接收用户输入的目标食材信息，该目标食材信息即为用户为该RFID标签自定义的食材信息；在接收到用户在该第一关联界面输入的目标食材信息后，将目标食材信息与该RFID标签相关联。
在一些实施例中，将目标食材信息与该RFID标签相关联是指，将目标食材信息与RFID标签的第二编码(即标签的标识信息)对应保存在本地数据中，本地数据中，食材信息与RFID标签的第二编码的对应关系用于根据在标签的第二编码已知的情况下，查找该标签对应的食材信息。
在一些实施例中，将目标食材信息与该RFID标签相关联还包括，根据当前时间生成食材ID，将食材ID与RFID标签的第二编码和目标食材信息一并对应保存在本地数据中，其中，当前时间包括但不限于指定控制器接收到目标食材信息的时间。在一些实施例中，用户可以通过操作食材管理界面输入用于指示进行标签识别的指令，例如，用户点击图3所示食材管理界面中的RFID标签识别控件以输入用户指令。当控制器接收到用于指示进行标签识别的指令时，在食材管理界面的显示用于提示用户将RFID标签放置在感应区域的TOEST提示(如图4A所示)，并指示感应区域的RFID检测模块开始识别RFID标签，以获取RFID标签的标签编码。
在一些实施例中，第一关联界面包括用于输入一项或者多项目标食材信息的一个或者多个输入位置，当检测到用户对输入位置的点击操作时，激活输入位置，以接收用户输入的文本信息，即目标食材信息。其中，根据第一关联界面中元素和布局的不同，用户在第一关联界面输入的目标食材信息包括但不限于食材名称、食材的保质期等。图4B为本申请根据示例性实施例示出的一种用户界面，具体为一种示例性的第一关联界面。如图4B所示， 该第一关联界面包括食材名称对应的输入位置和食材保质期对应的输入位置。
相应地，若第一编码不是预定编码，则根据该第一编码获取RFID标签的预设食材信息，将预设食材信息与该RFID标签相关联。在一些实施例中，将预设食材信息与该RFID标签相关联是指，将预设食材信息与RFID标签的第二编码对应保存在本地。在一些实施例中，将预设食材信息与该RFID标签相关联还包括，根据当前时间生成食材ID，将食材ID与RFID标签的第二编码和预设食材信息一并对应保存在本地数据中，其中，当前时间包括但不限于指定控制器获取到预设食材信息的时间。具体实现中，控制器可以根据第一编码从云端服务器获取对应的预设食材信息。或者，控制器可以根据第一编码从本地预置的第一编码与食材信息的对应关系表中获取对应的预设食材信息。其中，本地预置的对应关系表可以为控制器预先从云端服务器下载得到。
在上述一些实施例中，根据第一编码是否为预定编码判断该RFID标签对应的食材信息是否可由用户自定义，若第一编码是预定编码，说明RFID标签对应的食材信息可由用户自定义，因此显示可输入目标食材信息的第一关联界面，将接收到的目标食材信息与RFID标签进行对应，提高RFID标签的使用灵活性；若第一编码不是预定编码，说明该RFID标签对应的食材信息不可由用户自定义，则根据第一编码获取对应的预设食材信息，将该预设食材信息与RFID标签进行对应，节省用户操作，提高食材信息录入效率。
在一些实施例中，在显示第一关联界面时，根据第二编码(即RFID标签的标识信息)判断本地数据中是否存在与第二编码相对应的食材信息，若本地数据中存在与第二编码相对应的食材信息，则使用与该第二编码相对应的食材信息对第一关联界面中相应的输入位置进行预填充。这样一来，一方面，可以向用户展示该RFID标签当前已关联的食材信息，另一方面，若用户想要修改当前已关联的食材信息，则在各个输入位置输入新的食材信息即可。除此之外，若用户只想修改部分食材信息，则只需对部分食材信息进行重新输入即可，对于不想修改的另一部分食材信息则无需重新输入。若本地关联数据中不存在与所述RFID标签相关联的食材信息，则使用预置字符对所述第一关联界面中相应的输入位置进行预填充，例如图4B中输入位置处示出的“未定义”。
在一些实施例中，若第一编码不是预定编码，则在显示屏上显示包含预设食材信息的第二关联界面，与第一关联界面不同，第二关联界面不可接收用户输入的食材信息。图4C为本申请根据示例性实施例示出的一种用户界面，其具体为一种示例性的第二关联界面。如图4C所示，在该第二关联界面显示有食材名称“萝卜”、保质期“60天”。
本申请一些实施例还提供一种食材录入方法，该方法可以包括：
步骤701，响应于用户输入的指示对RFID标签进行识别的指令，获取RFID标签的标签编码，所述标签编码包括第一编码。例如，用户可以点击图3所示界面中的RFID标签识别控件以输入指示进行RFID标签识别的指令。响应于该指令，通过RFID检测模块识别RFID标签的信号，以获取RFID标签的标签编码。在本申请一些实施例中，标签编码包括第一编码，该第一编码为预定编码或者为非预定编码表征该RFID标签对应的预设食材信息被预先保存在云端服务器中，不可由用户自定义。
在一些实施例中，标签编码还包括第二编码，该第二编码为RFID标签的唯一性标识信息。在一些实施例中，RFID标签的标签编码包括符合预设组成规则的至少两个码段，分别为第一码段和第二码段，其中第一码段用于写入上述第一编码，第二码段用于写入上述第二编码。基于此，在获取到RFID标签的标签编码，可以根据标签编码的预设组成规则从中 截取出第一码段和/或第二码段以获取到第一编码和/或第二编码。
步骤702，判断所述第一编码是否为预定编码。若是，则执行步骤703；若否，则执行步骤705。步骤703，若所述第一编码为预定编码，显示第一关联界面，所述第一关联界面被配置为可接收用户输入的目标食材信息。
本申请一些实施例中，第一关联界面包括用于输入一项或者多项目标食材信息的一个或者多个输入位置，当检测到用户对输入位置的点击操作时，激活输入位置，以接收用户输入的文本信息，即目标食材信息。其中，根据第一关联界面中元素和布局的不同，用户在第一关联界面输入的目标食材信息包括但不限于食材名称、食材的保质期等。在一些实施例中，第一关联界面可如图4B所示，该第一关联界面包括食材名称对应的输入位置和食材保质期对应的输入位置。
步骤704，在接收到输入的所述目标食材信息后，将所述目标食材信息与所述RFID标签相关联。在一些实施例中，将所述目标食材信息与所述RFID标签相关联是指，将目标食材信息与所述RFID标签的标识信息对应保存在本地数据中。
步骤705，若所述第一编码不为预定编码，根据所述第一编码获取所述RFID标签的预设食材信息。具体实现中，可以根据第一编码从云端服务器获取对应的预设食材信息。或者，可以根据第一编码从本地预置的第一编码与食材信息的对应关系表中获取对应的预设食材信息。其中，本地预置的对应关系表可以为预先从云端服务器下载得到。
步骤706，将所述预设食材信息与所述RFID标签相关联。在一些实施例中，将所述预设食材信息与所述RFID标签相关联是指，将预设食材信息与所述RFID标签的标识信息对应保存在本地数据中。
在上述一些实施例中，根据第一编码是否为预定编码判断该RFID标签对应的食材信息是否可由用户自定义，若第一编码是预定编码，说明RFID标签对应的食材信息可由用户自定义，因此显示可输入目标食材信息的第一关联界面，将接收到的目标食材信息与RFID标签进行对应，提高RFID标签的使用灵活性；若第一编码不是预定编码，说明该RFID标签对应的食材信息不可由用户自定义，则根据第一编码获取对应的预设食材信息，将该预设食材信息与RFID标签进行对应，节省用户操作，提高食材信息录入效率。
<显性标签标识>
在一些实施例中，当控制器接收到用户输入的该指令后，响应于该指令，开始检测放置在感应区域的RFID标签的信号以获取RFID标签的标识信息。在控制器获取到RFID标签的标识信息后，在显示屏上呈现包含标识信息的编辑界面。图4D-4F为根据本申请一个或多个实施例的食材管理界面图，如图4D所示，该编辑界面显示有RFID标签的标识信息“20200005”、用于输入食材名称的输入位置、用于输入食材类别的输入位置以及“取消”控件和“确定”控件。再如，可以在服务器侧建立RFID标签的标识信息与食材信息的对应关系表并发布。在冰箱侧，由控制器从服务器获取该对应关系表并保存在本地；当需要在食材管理界面中显示冰箱内通过RFID标签标识的食材时，控制器根据当前放置在储藏室中的RFID标签的标识信息从本地保存的对应关系表查找与RFID标签的对应的食材信息，最后根据各个RFID标签对应的食材信息在食材管理界面中生成对应的食材控件。
在一些实施例中，本地保存的RFID标签与食材信息的对应关系中，多个RFID标签所关联的食材信息是相同的。例如从下述表4所示对应关系可以看出，标识3、标识4和标识5 对应的食材信息相同。
表4
RFID标签 食材信息
标识1 鸡蛋、农副产品类
标识2 黄瓜、蔬菜类
标识3 牛肉、肉类
标识4 牛肉、肉类
标识5 牛肉、肉类
…… ……
由于食材管理界面中的食材控件是根据储藏室中各个RFID标签对应的食材信息生成的，当储藏室中存在多个关联相同食材信息的RFID标签，那么食材管理界面中与该多个RFID标签对应的食材控件的显示效果相同，用户将难以通过食材控件区分该多个RFID标签(所标识的食材)，不利于用户体验。参考图4E，该食材管理界面显示出了根据表2所示标识信息为“标识3”的RFID标签对应的食材控件601、标识信息为“标识4”的RFID标签对应的食材控件602、标识信息为“标识5”的RFID标签对应的食材控件603等多个食材控件，可以看出，食材控件601、食材控件602和食材控件603的显示效果基本相同。可见，用户无法根据该三个看起来基本相同的食材控件区分该三个RFID标签所标识的食材，例如用户无法根据该三个食材控件取出最新鲜的食材或者最不新鲜的食材。为解决此问题，如下实施例提出可行的方案。
在一些实施例中，本地数据包括多个RFID标签的标识信息和对应的食材信息，根据每个RFID标签当前是放置在储藏室中还是已移出储藏室，将这些RFID标签分为第一类RFID标签和第二类RFID标签，其中，第一类RFID标签是指当前放置在储藏室中的RFID标签，第二RFID标签是指当前已移出储藏室的RFID标签。在一些实施例中，根据RFID标签的指定属性值判断该RFID标签是为第一类RFID标签还是第二类RFID标签，也就是说，第一类RFID标签与第二类RFID标签的指定属性值不同。示例性的，第一类RFID标签的指定属性值为0，第二类RFID标签的指定属性值为1。
需要说明的是，指定属性值的作用是区分第一类RFID标签和第二类RFID标签，本申请对指定属性值的具体形式不予限定，其可以是第一类RFID标签和第二类RFID标签所具有的不同的状态标记，如第一类RFID标签被标记的状态为存入状态，第二类RFID标签被标记的状态为移出状态，也可以是第一类RFID标签和第二类RFID标签所对应的不同的存储路径，如第一类RFID标签的标识信息保存在第一表格中，第二类RFID标签的标识信息保存在第二表格中。
在一些实施例中，冰箱的控制器被配置为：获取目标RFID标签关联的食材信息，该目标RFID标签是指当前放置在所述储藏室中的RFID标签，即上述第一类RFID标签；根据目标RFID标签关联的食材信息显示食材管理界面，食材管理界面中包括与每个目标RFID标签对应的食材控件，每个食材控件包括显性标签标识，其中，关联的食材信息相同的目标RFID标签所对应的显性标签标识不同。
在上述一些实施例中，在食材控件中增设显性标签标识，用以代表该食材控件对应的RFID标签。在根据各个目标RFID标签对应的食材信息生成食材控件时，将关联的食材信息相同的目标RFID标签对应的显性标签标识生成为不同。这样，用户便可根据显性标签标识来区分这些关联了相同的食材信息的RFID标签，实现对每个RFID标签、食材的单独管理。
在一些实施例中，每个RFID标签都具有一个属性标识，用于表征RFID标签对应的显性标签标识的属性，其中，显性标签标识的属性包括显性标签标识的内容属性、颜色属性。相应地，RFID标签的属性标识可以包括用于确定显性标签标识展示的内容的第一标识，和，用于确定显性标签标识的颜色的第二标识。在一些实施例中，RFID标签的属性标识具体可以写在RFID标签的标签编码的指定码段中，从标签编码中截取指定码段即可获取到RFID标签的属性标识。在一些实施例中，RFID标签的标签编码中包括上次食材预定义编码，该食材预定义编码用于确定RFID标签对应的食材信息。在建立RFID标签的标识信息与食材信息的对应关系时，根据RFID标签的食材预定义编码从食材预定义编码与食材信息的映射关系表中获取该RFID标签的食材信息，并将获取的食材信息与该RFID标签的标识信息对应保存在本地，得到RFID标签的标识信息与食材信息的对应关系。
在一些实施例中，关联相同食材信息的RFID标签的属性标识不同，进而，虽然有些RFID标签所关联的食材信息相同，但是其用于表征显性标签标识的属性标识不同，因此这些RFID标签对应的食材控件中的显性标签标识不同，进而实现对这些RFID标签的区分。在一些实施例中，任意两个RFID标签的属性标识不同，进而，无论该任意两个RFID标签所关联的食材信息是否相同，都可以根据其属性标识来区分任意两个RFID标签。在一些实施例中，为实现关联相同食材信息的RFID标签的属性标识不同，将用于确定RFID标签关联的食材信息的食材预定义编码一并写入到标签编码的另一指定码段中，进而保证食材预定义编码相同的RFID标签的属性标识不同。在另一些实施例中，RFID标签的属性标识可以是与RFID标签的标识信息对应保存的属性信息，根据RFID标签的标识信息便可以在本地数据中查找到RFID标签的属性标识。
在一些实施例中，冰箱的控制器被配置为：获取目标RFID标签的属性标识和对应的食材信息，该目标RFID标签是指当前放置在所述储藏室中的RFID标签，即前述第一类RFID标签；根据目标RFID标签的属性标识和对应的食材信息显示食材管理界面，食材管理界面包括与每个目标RFID标签对应的食材控件，每个食材控件包括显性标签标识，其中，属性标识不同的目标RFID标签对应的显性标签标识被显示为不同。
具体实现中，控制器可以根据本地保存的所有RFID标签的指定属性值从所有RFID标签中确定目标RFID标签；从目标RFID标签的标签编码中获取目标RFID标签的属性标识和唯一性标识，目标RFID标签的唯一性标识即为目标RFID标签的标识信息；最后，再根据目标RFID标签的唯一性标识，从本地保存的对应关系中获取目标RFID标签对应的食材信息。
在上述实施例中，在食材控件中增设显性标签标识，用以代表该食材控件对应的RFID标签。在根据各个目标RFID标签的属性标识和对应的食材信息生成食材控件时，由于属性标识表征了显性标签标识的内容、颜色等属性，因此不同的目标RFID标签对应的显性标签标识生成为不同，而由于关联的食材信息相同的RFID标签的属性标识不同，或者任意两个RFID标签的属性标识不同，因此关联的食材信息相同的RFID标签对应的显性标签标识不 同，或者任意两个食材控件的显性标签标识均不同，这样，用户便可根据显性标签标识来区分这些关联了相同的食材信息的RFID标签，或者区分任意两个RFID标签，进而实现对每个RFID标签、食材的单独管理。
<丝印>
在一些实施例中，RFID标签的属性标识包括第一标识，该第一标识用于确定在显性标签标识中展示的内容。在本申请实施例中，将在显性标识中展示的内容称为丝印内容。具体的，控制器根据目标RFID标签的属性标识和对应的食材信息显示食材管理界面的过程包括：控制器根据第一标识与丝印内容的预设对应关系，确定目标RFID标签对应的目标丝印内容；在目标RFID标签对应的食材控件中显示包含目标丝印内容的显性标签标识。其中，丝印内容可以是数字、文字、字母、图案等。
在一些实施例中，第一标识为RFID标签的标签编码的第一码段对应的编码，控制器截取目标RFID标签的第一码段，以获取目标RFID标签的第一标识。本申请根据示例性实施例示出的第一标识与丝印内容的预设对应关系，如下述表5所示：
表5
第一标识 丝印内容 第一标识 丝印内容 第一标识 丝印内容
0A A 0F F 14 K
0B B 10 G 15 L
0C C 11 H 16 M
0D D 12 I 17 N
0E E 13 J …… ……
从上述第一标识与丝印内容的预设对应关系可以看出，RFID标签的第一标识为2位16进制编码，丝印内容为字母。需要说明的是，可以通过改变第一标识位数和/或丝印内容的形式，来满足更多RFID标签的需求，以保证关联了相同食材信息的RFID标签的第一标识不同或者保证任意两个RFID标签的第一标识不同。
参考图4F，该食材管理界面显示出了根据表3所示标识信息为“标识3”的RFID标签对应的食材控件701、标识信息为“标识4”的RFID标签对应的食材控件702、标识信息为“标识5”的RFID标签对应的食材控件703，食材控件701、食材控件702和食材控件703分别包括显性标签标识7011、7021和7031，且显性标签标识7011、7021和7031不同。具体的，显性标签标识7011上显示的丝印内容为字母“A”、显性标签标识7021上显示的丝印内容为字母“D”，显性标签标识7031上显示的丝印内容为字母“G”。在一些实施例中，每个RFID标签对应的丝印内容(即与RFID标签的第一标识对应的丝印内容)与该RFID标签实体上印制的丝印内容一致，进而，用户可以根据显性标签标识所展示的丝印内容，对应找到储藏室中印制有相同丝印内容的RFID标签，或者，根据RFID标签实体上印制的丝印内容，对应找到食材管理界面中该RFID标签对应的食材控件。
图4G为根据本申请一个或多个实施例的RFID标签外观示意图，其具体为表3所示标识信息为“标识3”的RFID标签的外观示意图，如图4G所示，该RFID标签的签体801上印制的丝印内容802为字母“A”。实际使用中，用户可以根据如图4F所示食材管理界面中显示的显性标签标识7011，对应找到储藏室中印制有字母“A”的RFID标签，或者该印制有字母“A”的RFID标签，在对应找到食材管理界面中该RFID标签对应的食材控件。
在一些实施例中，显性标签标识展示的内容还可以包括根据RFID关联的食材信息预设的食材象形标志图案，即丝印图像。具体的，控制器根据食材预定义编码与丝印图像的预设对应关系获取目标RFID标签对应的目标丝印图像；在目标RFID标签对应的食材控件中显示包含目标丝印图像的显性标签标识。
在一些实施例中，RFID标签的属性标识包括第二标识，该第二标识用于确定显性标签标识的颜色。基于此，控制器在根据所述目标RFID标签的属性标识和对应的食材信息显示所述食材管理界面的过程还包括：根据第二标识与丝印颜色值的预设对应关系，确定目标RFID标签对应的目标颜色值，及RGB值；根据目标颜色值绘制目标RFID标签对应的显性标签标识的颜色。
图4H-4I为根据本申请一个或多个实施例的食材管理界面图，参考图4H，该食材管理界面显示出了根据表3所示标识信息为“标识3”的RFID标签对应的食材控件901、标识信息为“标识4”的RFID标签对应的食材控件902、标识信息为“标识5”的RFID标签对应的食材控件903等多个食材控件，食材控件901、食材控件902和食材控件903分别包括显性标签标识9011、9021和9031，与图4F所示食材管理界面中的显性标签标识7011、7021和7031相比，显性标签标识9011、9021和9031的颜色不同。
在一些实施例中，参考图4I，该界面中新增多个食材控件，即分别与多个新增食材标签对应的食材控件，具体包括根据默认填充信息生成的食材控件501、502和503，和，根据预设食材信息生成的食材控件504和505。根据默认填充信息生成的食材控件与其他食材控件相同的是，其也包括食材图标、食材名称等，与其他食材控件不同的是，其通过以“未定义”作为食材名称、以包含“未定”字样的图片文件作为食材图标，显性示出了其对应的RFID标签仍未与食材信息建立关联，即为未定义标签，或者称为未编辑标签，从而有效提醒用户及时对这些RFID标签进行编辑。
在一些实施例中，为实现对多个储藏室中的食材的分区管理，在食材管理界面中设置多个分别与储藏室对应的食材展示区，将各个储藏室中的食材对应的食材控件显示在相应的食材展示区中，从而方便用户快速识别出哪个储藏室中存放着哪些食材。
为进一步方便用户区分不同储藏室中的食材，在一些实施例中，将第二标识相同的目标RFID标签对应的食材控件显示在同一食材展示区中，第二标识不同的目标RFID标签对应的食材控件显示在不同的食材展示区中。也就是说，同一食材展示区中的食材控件的显性标签标识被绘制为相同的颜色，不同食材展示区中的食材控件的显性标签标识被绘制为不同的颜色。这样，用户便可以根据显性标签标识的颜色判断食材所在的储藏室。
本申请一些实施例提供一种食材管理方法，该方法可以包括：步骤101，获取目标RFID标签的属性标识和对应的食材信息，该目标RFID标签为当前放置在所述储藏室中的RFID标签，RFID标签用于标识所述储藏室中的食材。在一些实施例中，根据本地保存的所有RFID标签的指定属性值从所有RFID标签中确定目标RFID标签，指定属性值用于表征RFID标签当前是否放置在储藏室中；从目标RFID标签的标签编码中获取目标RFID标签的属性标识和唯一性标识；以及，根据目标RFID标签的唯一性标识获取目标RFID标签对应的食材信息。
步骤102，根据目标RFID标签的属性标识和对应的食材信息显示食材管理界面，食材管理界面包括与每个目标RFID标签对应的食材控件，食材控件包括显性标签标识，其中，属性标识不同的目标RFID标签对应的显性标签标识不同。在一些实施例中，属性标识包括 第一标识，根据目标RFID标签的属性标识和对应的食材信息显示食材管理界面，包括：根据第一标识与丝印内容的预设对应关系，确定目标RFID标签对应的目标丝印内容；在目标RFID标签对应的食材控件中显示包含目标丝印内容的显性标签标识。
在一些实施例中，目标RFID标签对应的目标丝印内容与目标RFID标签实体上印制的丝印内容一致。在一些实施例中，属性标识包括第二标识，根据目标RFID标签的属性标识和对应的食材信息显示食材管理界面，还包括：根据第二标识与丝印颜色值的预设对应关系，确定目标RFID标签对应的目标颜色值；根据目标颜色值绘制目标RFID标签对应的显性标签标识的颜色。在一些实施例中，食材管理界面包括多个食材展示区，第二标识相同的目标RFID标签对应的食材控件显示在同一食材展示区中，第二标识不同的目标RFID标签对应的食材控件显示在不同的食材展示区中。
在一些实施例中，当检测到所有箱门关闭时，识别所述储藏室中的RFID标签，得到包含最新识别到的每个RFID标签的标签编码的第零信息集合；通过对比所述第零信息集合与本地保存的第一信息集合和第二信息集合，确定最新移出的RFID标签和最新放入的RFID标签，所述第一信息集合包括所述指定属性值为第一值的RFID标签，所述第二信息集合包括所述指定属性值为第二值的RFID标签；将所述最新移出的RFID标签的指定属性值修改为所述第二值，以将所述最新移出的RFID标签标记为非目标RFID标签，所述非目标RFID标签为当前已移出储藏室的RFID标签，以及，将所述最新放入的RFID标签的指定属性值修改为所述第一值，以将所述最新放入的RFID标签标记为当前放置在储藏室中的RFID标签。
自动录入食材
在一些实施例中，为进一步提高冰箱智能化管理能力、提高用户体验，首先通过检测箱门的开关信号(包括开门信号和关门信号)获取箱门的开关状态(包括开启状态和关闭状态)，然后根据箱门的开关状态变化情况确定目标操作箱门，即被用户操作的箱门，根据目标操作箱门确定目标储藏室，最后将本次操作后储藏室内新增的食材归类到确定的目标储藏室，可见，该分区实现过程无需用户手动操作，实现了对食材的完全智能化管理。
在一些实施例中，图5A-5B为根据本申请一个或多个实施例的食材管理界面图，在显示屏显示如图3所示的食材管理界面时，用户可以点击自定义区触发对自定义区中的食材进行分区归类操作流程。示例性的，响应于用户对自定义区的点击，显示如图5A所示的虚拟存储界面，在该虚拟存储界面中，显示有待分区存储的食材信息和可被分配的储藏室选项，以及相关功能控件，如“确定”、“取消”等。用户通过操作虚拟存储界面中的控件，实现对自定义区中的食材进行分区存储。
<开关门检测>
在一些实施例中，冰箱还包括检测器，用于分别检测每个所述箱门的开关信号，根据检测到的开关信号记录所述箱门的开关状态，发送开关状态信息给控制器，所述开关状态信息中包括每个所述箱门最近两次的开关状态。示例性的，通过记录箱门的在先状态(Oldstate)和在后状态(Newstate)记录箱门的开关状态变化过程，比如，当检测到箱门的开启信号时，记录箱门的在后状态为开启状态(Newstate＝开启)，在检测到该开启信号前记录的在后状态(关闭状态)自动更新为在先状态，接着，当检测到箱门的关闭信号时，记录箱门的在后状态为关闭状态(Newstate＝关闭)，在检测到该关闭信号之前的在后状态(开启状态)自动更新为在先状态。
在一些实施例中，当检测器检测到任意一个箱门的开启信号或者关闭信号时，向控制器发送开关状态信息，开关状态信息中包括每个箱门最近两次的开关状态，即前述在先状态和在后状态。示例性的，检测器发送给控制器的开关状态信息中各字段内容如下表6所示：
表6
Figure PCTCN2021103101-appb-000002
在一些实施例中，控制器接收检测器发送的开关状态信息，根据接收到的开关状态信息分析用户对箱门的操作行为。为便于说明，本申请将被用户操作的箱门称为目标操作箱门，目标操作箱门即是指开关状态发生变化的箱门。具体的，如果箱门的在先状态为开启状态，在后状态为关闭状态，说明用户对该箱门执行了完整的开关操作，确定该箱门为目标操作箱门。例如，根据上述示例性示出的开关状态信息所包含的内容可以确定，冷藏室门未被操作，变温室门被开启但未被关闭，冷冻室被先被开启后被关闭，因此确定目标操作箱门为冷冻室门和变温室门。在本申请一些实施例中，检测器具体可以通过检测磁敏开关、机械开关检测箱门的开关信号。
在一些实施例中，控制器，根据目标操作箱门确定目标储藏室，具体的，当目标操作箱门的数量为1个时，确定该目标操作箱门对应的储藏室为目标储藏室，当目标操作箱门的数量为多个时，确定预设的虚拟储藏室为目标储藏室，例如图3所示实施例中的自定义区。示例的，若根据箱门状态信息确定目标操作箱门为冷藏室门时，那么目标储藏室则为冷藏室。若根据箱门状态信息确定目标操作箱门包括冷藏室和冷冻室时，那么目标储藏室则为虚拟储藏室。
在一些实施例中，检测器每检测到一个箱门的开启信号，便向控制器发送一次开关状态信息，直到检测到最后一个被开启的箱门的关闭信号，向控制器发送最后一个开关状态信息。控制器根据接收到的开关状态信息判断是否所有的箱门均已关闭，即判断是否所有箱门的在后状态均为关闭状态，在所有箱门均关闭后，指示与其连接的RFID检测模块识别所有储藏室内的所有RFID标签，以获取储藏室内每个食材对应的RFID标签的标识信息，得到第一信息集合。
<食材与存储区域建立映射关系>
控制器在通过RFID检测模块获取到第一信息集合后，可以将第一信息集合与第二信息集合进行比较，以确定本次操作放入冰箱和/或取出冰箱的食材，其中，第二信息集合是根据上一次检测到所有箱门均关闭时获取的标识信息生成的信息集合。以上一次检测到所有箱门均关闭时获取的、包含所有RFID标识信息的第零信息集合为例，第二信息集合根据第零信息集合生成得到，具体的，将上一次移出冰箱的食材对应的RFID标签的标识信息添加到第零信息集合中，并标记为移出状态，得到第二信息集合。可见，第二信息集合 与第零信息集合的区别在于，第二信息集合中包括曾经放入到冰箱，且，已经移出冰箱的RFID标签的标识信息。以本次检测到所有箱门均关闭时获取的第一信息集合为例，根据第一信息集合可以生成第三信息集合，具体的，通过对比第一信息集合与第二信息集合，确定本次移出储藏室的食材对应的RFID标签，即标识信息仅在第二信息集合中存在的RFID标签，将本次移出所述储藏室的RFID标签的标识信息添加到第一信息集合中，并将其标记为移出状态，生成第三信息集合。
在一些实施例中，控制器通过对比第一信息集合和第二信息集合，确定本次放入冰箱的食材对应的标签，即目标标签，并根据确定的目标标签及目标储藏室，显示食材管理界面，食材管理界面中，通过目标标签所标识的食材的存储位置为目标储藏室。其中，目标储藏室为目标操作箱门对应的储藏室或者预设的虚拟储藏室。在根据目标标签和目标储藏室显示食材管理界面时，将目标标签对应的食材信息加载在目标储藏室对应的食材展示区，例如，在目标储藏室为冷藏室时，将目标标签关联的食材信息(如黄瓜)展示在冷藏室对应的食材展示区，在目标储藏室为虚拟储藏室时，将目标标签关联的食材信息展示在虚拟储藏室对应的食材展示区，如图3中示出的自定义区。
在一些实施例中，目标标签可以是第一目标标签，该第一目标标签是指标识信息在第一信息集合和第二信息集合中同时存在且在第二信息集合中被标记为移出状态的RFID标签，用户通过本次操作将第一目标标签对应的食材再次放入到储藏室中。在一些实施例中，上述目标标签还可以是第二目标标签，该第二目标标签是指标签信息在第一信息集合中存在、在第二信息集合中不存在的RFID标签，用户通过本次操作将第二目标标签对应的食材首次放入到储藏室中。
在一些实施例中，用户可以通过操作食材管理界面对存储位置为虚拟储藏室的食材进行一键分区，避免逐一对每一样食材进行操作。具体实现中，在显示屏显示食材管理界面时，用户可以通过操作食材管理界面输入第一指令，例如点击虚拟储藏室对应的食材展示区的任意位置或者指定位置，或者，点击食材管理界面提供的指定功能控件等。控制器接收用户输入的第一指令，在食材管理界面的上层显示虚拟存储界面，在虚拟存储界面中展示有存储位置为虚拟储藏室的食材和对应的推荐储藏室，其中，每个食材对应的推荐储藏室是根据食材与储藏室的预设对应关系确定的。示例性的，图5B为根据本申请一个或多个实施例的一种用户界面，具体为一种示例性的虚拟存储界面。如图5B所示，在该虚拟存储界面中，展示有虚拟储藏室的食材和对应的推荐储藏室。
在一些实施例中，预先获取食材与储藏室之间的预设对应关系表，根据该预设对应关系表，即可根据虚拟储藏室中的食材信息确定其对应的推荐储藏室，例如，虚拟储藏室中包括黄瓜，根据预设对应关系表中黄瓜对应的储藏室是冷藏室，则在虚拟存储界面中显示黄瓜对应的推荐储藏室为冷藏室。在显示屏显示虚拟存储界面时，用户可以通过操作虚拟存储界面输入第二指令，例如点击虚拟存储界面中显示的指定功能控件(如图5示出的“确定”控件)。控制器接收用户输入的第二指令，将虚拟储藏室中的食材的存储位置由虚拟储藏室修改为对应的推荐储藏室，进而，实现对虚拟储藏室中的食材的一键分区。完成一键分区操作后，虚拟储藏室中的食材将展示在推荐储藏室对应的展示区中。在一些实施例中，虚拟存储界面中除展示与食材对应的推荐储藏室以外，还可以展示其他储藏室选项以供用户选择，以便实现对食材的个性化存储。
由以上一个或多个实施例可知，通过检测箱门的开关信号确定判断用户是否操作箱门， 并在箱门的开关状态发生变化时，根据箱门的开关状态情况确定目标操作箱门，在箱门全部关闭后，根据确定的目标操作箱门确定目标储藏室，最后将储藏室新增的食材归类到目标储藏室中，实现了对食材存储位置的自动识别，对食材的分区管理过程无需用户手动操作，提升用户体验。
图6-图7为根据本申请一个或多个实施例的食材管理方法流程图，参考图6，本申请一些实施例提供一种食材管理方法，该方法可以包括：步骤601，当冰箱的至少一个箱门的开关状态发生变化后，根据所述箱门的开关状态变化确定目标操作箱门，所述目标操作箱门为所述开关状态由开启状态变化到关闭状态的箱门。当检测到箱门的开启信号或者关闭信号时，记录箱门的最新开关状态，并确定箱门的开关状态发生变化。根据箱门的开关状态变化过程，可以确定被用户操作(开启和/或关闭)的目标操作箱门，其中，目标操作箱门是指开关状态发生变化的箱门，例如，由开启状态变化为关闭状态的箱门，或者由关闭状态变化到开启状态的箱门。
步骤602，根据所述目标操作箱门确定目标储藏室，所述目标储藏室为所述目标操作箱门对应的储藏室或者预设的虚拟储藏室。具体实现中，可以在目标操作箱门的数量为1时，确定目标操作箱门对应的储藏室为目标储藏室；在目标操作箱门的数量大于1时，确定预设的虚拟储藏室为目标储藏室。目标储藏室为用户本次操作箱门所放入冰箱的食材的存储位置。
步骤603，当所有箱门的开关状态均变化到关闭状态后，获取第一信息集合，所述第一信息集合包括所述储藏室内每个食材对应的RFID标签的标识信息。通过RFID检测模块识别冰箱内每个RFID标签的信号，以获取RFID标签的标识信息，获取到的每个RFID标签的标识信息形成第一信息集合。
步骤604，对比所述第一信息集合与第二信息集合，确定放入所述储藏室的目标标签，所述第二信息集合为根据上一次检测到所有箱门的开关状态均变化到关闭状态后获取的标识信息生成的信息集合。目标标签包括第一目标标签和第二目标标签，第一目标标签是指标识信息在第一信息集合和第二信息集合中同时存在且在第二信息集合中被标记为移出状态的RFID标签，可以理解，第二目标标签在本次操作前被移出冰箱，通过本次操作再次被放入冰箱。第二目标标签是指标识信息仅在所述第一信息集合中存在的RFID标签，可以理解，第二目标标签为通过本次操作首次被放入冰箱的RFID标签。
步骤605，显示食材管理界面，所述食材管理界面中，通过所述目标标签标识的食材的存储位置为所述目标储藏室。如图3所示，在食材管理界面中，每个储藏室对应一个食材展示区，用于展示相应储藏室中的食材信息。在步骤605中，根据目标标签和目标储藏室显示食材管理界面，具体是将目标标签对应的食材信息加载在目标储藏室对应的食材展示区中进行展示。例如，将一个或者多个目标标签对应的食材信息展示目标储藏室对应的食材展示区，所述目标储藏室可能是冷藏室、冷冻室等中的一个，也可能是虚拟储藏室。
参考图7，本申请一些实施例还提供一种食材管理方法，该方法应用于上述实施例提供的冰箱，该方法的执行主体包括但不限于冰箱的控制器。该方法可以包括：步骤701，当检测到所有箱门关闭时，识别冰箱储藏室中的RFID标签，得到每个所述RFID标签的标签编码，所述RFID标签用于标识储藏室中的食材。
步骤702，根据所述RFID标签的标签编码判断所述RFID标签是否为新增RFID标签，所述新增RFID标签为未关联食材信息的RFID标签；若是，则执行步骤703，若否，则执 行步骤704。在一些实施例中，从标签编码中获取在第一码段中写入的第一编码；查找本地信息集合中是否存在该RFID标签的第一编码，该本地信息集合包括已关联食材信息的RFID标签的第一编码；若本地信息集合中不存在该RFID标签的第一编码，则判定该RFID标签是新增RFID标签；若本地信息集合中存在该RFID标签的第一编码，则判定该RFID标签不是新增RFID标签。
步骤703，若所述RFID标签是所述新增RFID标签，则根据所述新增RFID标签的标签编码获取所述新增RFID标签对应的预设食材信息。在一些实施例中，从新增RFID标签的标签编码中获取在第二码段中写入的第二编码；判断新增RFID标签的第二编码是否为预定编码；若新增RFID标签的第二编码是预定编码，则获取预置的默认填充信息，以作为该新增RFID标签的预设食材信息；若新增RFID标签的第二编码不是预定编码，则根据新增RFID标签的第二编码，从第二编码与食材信息的预设对应关系中获取新增RFID标签对应的预设食材信息。在一些实施例中，根据新增RFID标签的标签编码获取新增RFID标签对应的预设食材信息之后，将新增RFID标签的标签编码和其对应的预设食材信息对应保存在本地信息集合中。
步骤704，若所述RFID标签不是所述新增RFID标签，则根据所述RFID标签的标签编码获取所述RFID标签关联的食材信息。
步骤705，更新包括根据所述RFID标签关联的食材信息生成的食材控件的食材管理界面，更新后的所述食材管理界面中，所述新增RFID标签对应的食材控件是根据所述新增RFID标签对应的预设食材信息生成的，其他RFID标签对应的食材控件是根据所述其他RFID标签关联的食材信息生成的，其他RFID标签是指识别到的除新增RFID标签以外的RFID标签。
