下面以冰箱为例，做一示例性的阐述。图1b为本申请根据示例性实施例示出的冰箱立体图，本发明实施例提供的冰箱的形状近似长方体。冰箱的外观由提供有限储存空间的储藏室101和设置在储藏室101开口处的多个箱门200限定。储藏室101为具有开口的箱 体100，在图1b所示示例中，储藏室101被包括位于下方的冷冻室101A以及位于上方的冷藏室101B，冷冻室101A和冷藏室101B分别具有一个或者多个独立的储存空间。
在一些实施例中，冷冻室101A可通过抽屉式冷冻室门200A选择性地覆盖。冷藏室101B被隔成左侧和右侧。冷藏室101B通过可枢转地安装在冷藏室101B上的冷藏室门200B选择性地打开或者关闭。
图1c为本申请根据示例性实施例示出的冰箱外观示意图，如图1b所示，在冷藏室门200B上设有显示屏，显示屏嵌入到门体中。在一些实施例中，显示屏的屏幕所在平面与箱门外表面平齐。
如图1b和图1c所示，本申请实施例提供的冰箱，其箱体内部设有至少两个储藏室，如冷冻室、冷藏室、变温室和/或保鲜室等。每个储藏室中可以具有多个独立的存储空间，如抽屉式间室。
图2为本申请根据示例性实施例示出的冰箱硬件配置示意图，作为示例，冰箱200可以包括显示屏210、控制器220、存储器250和若干用户输入接口。
在一些示例性实施方式中，冰箱200还可以包括至少一个RFID检测模块230、检测器240。显示屏210、RFID检测模块230、检测器240、存储器250通过通信接口与控制器220耦合。其中，显示器210，用于接收控制器220输出的图像信号，进行显示视频内容和图像以及菜单操控界面的组件，以及显示用于控制冰箱200的用户操控UI界面。
控制器220，可以包括一个或者多个处理单元，例如系统芯片(system on a chip，SoC)、中央处理器(central processing unit，CPU)、微控制器(microcontroller，MCU)、存储控制器等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。
存储器250，可以包括一个或者多个存储单元，例如可以包括易失性存储器(volatile memory)，如：动态随机存取存储器(dynamic random access memory，DRAM)、静态随机存取存储器(static random access memory，SRAM)等；还可以包括非易失性存储器(non-volatile memory，NVM)，如：只读存储器(read-only memory，ROM)、闪存(flash memory)等。其中，不同的存储单元可以是独立的器件，也可以集成或者封装在一个或者多个处理器或者通信接口中，成为处理器或者通信接口的一部分。
检测器240，至少包括声音采集器，如麦克风，可以用于接收用户的声音。示例性的，包括用户控制冰箱200的控制指令的语音信号。
用户输入接口，包括麦克风、触摸板、传感器、按键等其他输入接口中至少一者。如：用户可以通过语音、触摸、手势、按压等动作实现用户指令输入功能，输入接口通过将接收的模拟信号转换为数字信号，以及数字信号转换为相应指令信号，发送至冰箱200。
在一些实施例中，控制器220可以包括语音识别模块，语音识别模块进一步包括语音解析单元和语音指令数据库，从而使冰箱可以独立完成对用户输入的语音数据的语音识别，以及将识别出的语音内容与语音指令数据库中的语音指令进行匹配的过程。
在一些示例性实施例中，RFID检测模块230可以设置在每个储藏室内，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标签中的食材信息。
在一些实施例中，冰箱还包括设置在储藏室外部的标签读取区，即用于识别RFID标签的感应区域，在标签读取区处设置RFID检测模块，用于检测放置在该区域的RFID标签。可选的，标签读取区可以设置在显示屏的下方，以便用户同时放置(或取走)RFID 标签在标签读取区和操作显示屏显示的用户界面。
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，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。且，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。
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。
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。其中，RFID标签的标识信息可以为RFID检测模块230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，控制器220可以根据每个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所示：
RFID 食材信息
标识1 苹果
标识2 黄瓜
标识3 猪肉
…… ……
在建立RFID标签与食材信息的对应关系后，控制器220通过检测RFID标签的信号获取RFID标签的标签编码，根据标签编码即可确定各标签关联的食材信息。
在一些实施例中，各标签关联的食材信息关联一个储藏室，根据食材信息关联的储藏室即可确定该食材的存放位置，如食材信息“苹果”与“冷藏室”关联，可以确定苹果存放在冷藏室中。
在一些实施例中，在显示屏210上显示食材管理界面，用户通过操作食材管理界面管理冰箱中的食材。比如，根据储藏室内每个RFID标签关联的食材信息在食材管理界面中绘制对应的食材控件/图标，使得冰箱中的食材以图标、图文等形式尽数展示。此外，还可以在食材管理界面中绘制功能控件，如RFID标签识别控件、食材添加控件等等，以供用户操作以触发控制器210实现相应功能。
图3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食材管理界面。参阅图3，该食材管理界面包括RFID标签编辑控件、推荐菜谱控件和与各个储藏室对应的食材展示区，如冷藏室对应的食材展示区310，每个食材展示区中显示有相应的食材图标和食材名称，如食材展示区310中的食材图标“苹果”311。
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，即为自定义 标签；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或者额本地食材库中，不可由用户自定义，即为预定义标签。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。需要说明的是，用户自定义食材名称是指用户可以根据需求将任意食材名称与RFID标签关联起来，同时，用户也可以根据需求的变化更改定义过的标签，从而使同一标签前后与不同的食材名称相关联，而用户不可以自定义食材名称即是指用户不可以更改与RFID标签关联的食材名称，此类RFID标签关联的食材名称被预先定义，并保存在云端服务器中或者本地食材库中。
当给定一RFID标签后，该标签是为预定义标签，还是为自定义标签，可以根据标签编码所包含的第一编码确定。若第一编码是预定编码，则该标签是自定义标签，若第一编码不是预定编码，则该标签是预定义标签。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：
Figure PCTCN2021114091-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。在另一些实施例中，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所示：
RFID第一编码 食材名称
01 萝卜
02 胡萝卜
03 莲藕
…… ……
在一些实施例中，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编辑的指令，例如，用户点击食材管理界面提供的食材信息编辑控件以指示进行食材信息编辑；当控制器接收到该指令后，开始检测放置在标签读取区上的RFID标签的信号以获取RFID标签的标识信息，并显示用于对该RFID标签关联的食材信息进行编辑的界面，即食材编辑界面，在食材编辑界面中输入用于与该RFID标签关联的食材信息。
在一些实施例中，食材编辑界面中还可以显示获取到的RFID标签的标识信息，从而 使用户可以直观看到RFID标签的标识信息，且无需用户手动输入标识信息，提升用户体验。
在一些实施例中，食材编辑界面中显示至少一个食材编辑项目，每个食材编辑项目包括项目名称和项目内容，其中，项目内容即为待编辑的部分，用户可以通过在输入位置处输入各食材编辑项目的项目内容，输入用于与该RFID标签进行关联的食材信息。输入完成后，控制器将输入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。
在一些实施例中，用于编辑食材信息的界面可以称为食材编辑界面，其上显示的食材编辑项目可以包括食材名称编辑项目、食材保质期编辑项目、食材数量编辑项目，等等。应理解，食材名称编辑项目的项目名称可以为“标签名称”，项目内容即为待输入或更新的食材名称，食材保质期编辑项目的项目名称可以为“保质期”，项目内容即为待输入或更新的保质期，食材数量编辑项目的项目名称可以为“数量”，项目内容即为待选择或更改的数量。
如图3所示，用户可以点击该界面中的RFID标签编辑控件以输入指示进行食材信息编辑的指令。响应于该指令，控制器控制RFID检测模块开始检测标签读取区上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，在显示屏上呈现食材编辑界面。
在一些实施例中，当控制器接收到用户输入的指示进行食材信息编辑的指令后，响应于该指令，显示标签扫描界面，在标签扫描界面中显示扫描提示，通过显示该扫描提示，提示用户将待编辑的RFID标签放置在标签读取区上。同时，控制器控制RFID检测模块开始检测标签读取区上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，在显示屏上呈现食材编辑界面。
在一些实施例中，用户也可以通过说出预设语音口令，以指示进行食材信息编辑的指令。比如，用户说出：“标签编辑”。当接收到用户输入的语音数据且识别出内容为“标签编辑”时，确认接收到输入的用于触发对RFID标签对应的食材信息进行编辑的预设语音指令。此时，控制器响应于该指令，显示标签扫描界面，并开始检测标签读取区上的RFID标签。
在一些实施例中，当接收到输入的预设语音指令时，首先判断是否检测到标签读取区上的RFID标签，若未检测到标签读取区上的RFID标签，说明用户还未将待编辑的RFID标签放置在标签读取区上，此时，再显示包含扫描提示的标签扫描界面，以提示用户将待编辑的RFID标签放置在所述标签读取区。
在一些实施例中，上述用于指示进行食材信息编辑的指令，还被称为RFID标签编辑指令。
图4为本申请在一些实施例中示出的用户界面，具体为一种示例性的标签扫描界面，如图4所示，该标签扫描界面上显示有扫描提示，其具体内容为“请将RFID标签防止在屏幕下方扫描区”。当检测到用户放置在标签读取区上的RFID标签时，显示如图5所示的食材编辑界面。
参阅图5，在该食材编辑界面上，显示有RFID标签的标识信息“20200005”，这样，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。在该食材编辑界面上，还显示有多个食材编辑项目，分别为食材名称编辑项目510、食材保质期编辑项目520， 其中，每个食材编辑项目对应有用于输入相应项目内容的输入位置。以及，显示有“取消”控件530和“确定”控件540。
这样，令每个RFID标签都与用户输入的食材信息对应起来，实现了RFID标签与食材信息之间的虚拟关联，根据RFID标签的标识信息即可查找到对应的食材信息，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，用户可以通过语音指令，编辑RFID标签对应的食材信息，比如，用户可以说：“定义2斤牛肉标签”，控制器即可根据识别出的“牛肉”、“2斤”等语音内容，自动更新相应食材编辑项目的项目内容，而无需用户输入文字。这样，不但可以进一步减少用户操作，令编辑过程更加快捷，还可以提高该功能的普适程度，令不会打字的老人或小孩也可以完成食材信息的编辑。
在一些实施例中，当控制器检测到用户放置在标签读取区上的RFID标签时，在显示上述食材编辑界面的同时，显示语音识别界面，并开始接收、识别用户的语音输入，其中，语音识别界面中可以显示输入提示和识别出的语音内容；根据识别出的语音内容，更新界面中食材编辑项目的项目内容。
图6为本申请在一些实施例中示出的用户界面，具体为一种同时显示食材编辑界面和语音识别界面的用户界面，如图6所示，语音识别界面所在的视图显示区610显示在食材编辑界面所在视图显示区620的上层，语音识别界面中显示有输入提示，具体为内容是“你可以说，我要定义2斤水蜜桃”的文字提示。当接收到用户输入的语音数据并识别出语音内容时，语音识别界面还可以显示识别出的语音内容。
在一些实施例中，控制器接收到用户输入的语音数据，将语音数据发送给服务器；服务器识别该语音数据得到对应的语音内容，根据语音内容生成语音指令，语音指令包括多个字段，一个字段对应一个食材编辑项目，字段名称即为项目名称，字段值即为项目内容。服务器将生成的语音指令返回给冰箱，冰箱根据语音指令中各字段的字段值更新对应食材编辑项目的项目内容。
一种示例性的语音指令格式如下：
字段名称 字段值
cmd RFID-write
name 牛肉
count 1000g
由上述语音指令可以看出，该语音指令指示冰箱执行RFID标签编辑操作，其中，字段名称“name”对应的字段值“牛肉”用于更新食材名称编辑项目的项目内容，字段名称“count”对应的字段值“1000g”用于更新食材数量编辑项目。
在一些实施例中，在控制器检测到用户放置在标签读取区上的RFID标签后，判断该RFID标签是否是自定义标签，若该RFID标签是自定义标签，则显示第一编辑界面，该第一编辑界面中包括多个食材编辑项目，其中，在每个食材编辑项目对应的项目内容显示区域(即输入位置区域)显示预置的默认字符，每个食材编辑项目的项目内容都是可以被编辑的。这样，用户可以通过输入文字或者输入语音的方式，更新每个食材编辑项目的项目内容。而若该RFID标签不是自定义标签，则根据标签编码中的第一编码获取该标签对应的预设食材信息，根据获取到的预设食材信息显示第二编辑界面。与第一编辑界面不同的 是，第二编辑界面中，在每个食材编辑项目对应的项目内容显示区域中显示预设食材信息，如预设食材名称等，并且，食材名称项目的项目内容是不可被编辑的，即用户不可通过输入文字或者输入语音的方式更改当前显示的食材名称。
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食材库中获取对应的预设食材信息。其中，本地预置的食材库可以为控制器预先从云端服务器下载得到。
在一些实施例中，若用户放置在标签读取区上的RFID标签是自定义标签，根据标签编码中的第二编码(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，则将该食材信息作为各食材编辑项目的项目内容，显示在第一编辑界面，显示第一编辑界面中。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，则以通过文字输入操作或者语音输入操作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。若本地数据中不存在与该RFID标签相关联的食材信息，则将预置的默认字符作为各食材编辑项目的项目内容，显示在第一编辑界面中。
图7为本申请在一些实施例中示出的一种可能的用户界面，其具体为一种示例性的第一编辑界面，如图7所示，在该界面中，各食材编辑项目的项目内容均为默认字符“未定义”。
图8为本申请在一些实施例中示出的一种可能的用户界面，其具体为一种示例性的第二编辑界面，如图8所示，在该界面中，食材名称编辑项目810的项目内容为默认字符“苹果”、保质期编辑项目820的项目内容为默认字符“1”、食材数量编辑项目830的项目内容为默认字符“1”。其中，“苹果”、“1”等即为当前检测到的标签对应的预设食材信息。
如前所述，对于预定义标签，其关联的食材名称是与不可编辑的，对于自定义标签，其关联的食材名称是可以编辑的。基于此，冰箱控制器在根据服务器返回的语音指令更新食材编辑项目时，若RFID标签是自定义标签，则对所有食材编辑项目内容进行更新，若RFID标签不是自定义标签，则对除食材名称编辑项目以外的食材编辑项目的项目内容进行更新。
应当理解，根据预设语音指令包含的语音内容显示或者更新各食材编辑项目的项目内容的过程，可以参见如图1a-图8示出的实施例，比如，在RFID标签是自定义标签时，对所有食材编辑项目进行更新，在RFID标签不是自定义标签时，对除食材名称编辑项目以外的食材编辑项目进行更新，等等，此处不予赘述。
由以上实施例可以看出，基于本申请实施例提供的冰箱，用户可以通过语音输入，对RFID标签对应的食材信息进行编辑。具体的，当检测到用户放置在标签读取区上的RFID标签时，在显示食材编辑界面的同时，显示语音识别界面，即自动将语音应用切换到前台运行，从而快速进入到语音检测状态，及时检测用户的语音输入，用户通过说出想要编辑的食材信息，即可使冰箱自动完成信息输入过程，节省用户操作，且令编辑过程更加快捷，提高用户体验。
图9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食材库界面。如图9所示，该界面中包括名称为“最近使用”、“全部”、“水果”、“蔬菜”、“肉 类”、“饮品”、“水产”、“其他”和“自定义”的操作控件111-119。在图9中，由于“全部”控件112被选中，因此在该界面中显示食材全集中每个食材信息对应的食材图标。在显示图9所示界面时，若用户点击“自定义”控件119，用户界面由图9变化为图10，在图10所示界面中，显示有自定义食材集合中每个食材信息对应的食材图标。
如图10所示，在显示自定义食材集合的食材库界面中，还显示有用于添加自定义食材信息的操作控件121。用户可以通过操作该操作控件121输入用于添加自定义食材的指令，控制器响应于该指令，显示食材定义界面，用户可以在食材定义界面中输入新定义的食材信息。
在一些实施例中，在图9和图10所示用户界面中，用户可以通过预定操作选中一个或者多个食材图标，比如通过长按图标的操作，选中图标。还可以通过预定操作取消对图标的选中，比如长按处于选中状态的图标，以取消对该图标的选中。
本申请实施例还提供一种食材信息编辑方法，该方法应用于如图1a-图10所示的冰箱，该方法的执行主体包括但不限于冰箱的控制器。图11为本申请根据示例性实施例示出的食材信息编辑方法流程图，如图11所示，该方法可以包括：
S010，当检测到所述标签读取区上的RFID标签时，显示包括食材编辑界面和语音识别界面的用户界面，并识别输入的语音内容，所述食材编辑界面用于显示输入的食材信息，所述语音识别界面包括输入提示和识别出的语音内容。
在一些实施例中，接收输入的RFID标签编辑指令，例如用户在如图3所示界面中，通过点击RFID标签编辑控件，而输入RFID标签编辑指令；响应于输入的RFID标签编辑指令，检测标签读取区上的RFID标签。
在另一些实施例中，接收输入的预设语音指令，该预设语音指令用于触发对RFID标签对应的食材信息进行编辑，比如，用户说出预设语音口令，以输入该预设语音指令，比如说出“标签编辑”。响应于输入的预设语音指令，检测标签读取区上的RFID标签。
在一些实施例中，接收输入的预设语音指令，响应于该预设语音指令，显示标签扫描界面，该标签扫描界面中显示扫描提示，该扫描提示用于提示用户将待编辑的RFID标签放置在标签读取区。同时，检测标签读取区上的RFID标签。
S011，根据识别出的所述语音内容，在所述食材编辑界面中显示输入的食材信息。
在一些实施例中，所述当检测到用户放置在标签读取区上的RFID标签时，显示食材编辑界面，包括：获取通过检测所述RFID标签得到的标签编码，所述标签编码包括用于表征所述RFID标签是否为自定义标签的码段；根据所述标签编码判断所述RFID标签是否是自定义标签；若所述RFID标签是自定义标签，将预置的默认字符作为各食材编辑项目的项目内容，显示在所述食材编辑界面中。例如，在图7所示食材编辑界面中，各食材编辑项目的项目内容均为默认字符“未定义”。若所述RFID标签不是自定义标签，根据标签编码获取所述RFID标签的预设食材信息，将预设食材信息作为各食材编辑项目的项目内容，显示在所述食材编辑界面中。例如，在图8所示食材编辑界面中，食材名称编辑项目的项目内容为默认字符“苹果”、保质期编辑项目的项目内容为默认字符“1”、食材数量编辑项目的项目内容为默认字符“1”。其中，“苹果”、“1”等即为当前检测到的标签对应的预设食材信息。
在一些实施例中，所述根据识别出的所述语音内容，更新所述食材编辑项目的项目内容，包括：接收用户输入的语音数据，将所述语音数据发送给服务器，以使服务器识别语 音内容；接收服务器根据识别出的语音内容返回的语音指令，所述语音指令包括多个字段，一个字段对应于一个所述食材编辑项目；利用所述字段的字段值更新与所述字段对应的食材编辑项目的项目内容。
在一些实施例中，所述食材编辑项目包括食材名称编辑项目，所述根据识别出的所述语音内容，更新所述食材编辑项目的项目内容，包括：若RFID标签是自定义标签，则根据所述语音内容更新所有食材编辑项目的项目内容；若RFID标签不是自定义标签，则根据所述语音内容更新除所述食材名称编辑项目外的食材编辑项目的项目内容。
在一些实施例中，若所述RFID标签不是自定义标签，还包括：判断所述语音内容中包含的食材名称与所述预设食材信息中包含的预设食材名称是否相同；若所述语音内容中包含的食材名称与所述预设食材信息中包含的预设食材名称不相同，则显示界面提示，或者，播放语音提示，所述界面提示和所述语音提示用于提示用户所述RFID标签不支持编辑食材名称。例如，如果当前检测到的RFID标签对应的预设食材名称是“苹果”，语音指令中字段名称“name”对应的字段值“牛肉”，由于二者不同，因此需要弹出文字提示或者播放语音提示。如若当前检测到的RFID标签对应的预设食材名称是“牛肉”，由于语音指令中字段名称“name”对应的字段值也是“牛肉”，因此无需弹出文字提示或者播放语音提示。
在一些实施例中，所述控制器还用于：接收对所述食材编辑界面上指定控件的确认操作；响应于所述确认操作，根据所有食材编辑项目更新后的项目内容生成食材信息；将所述食材信息和所述RFID标签的标签编码对应保存在本地数据中。
图12为本申请根据示例性实施例示出的另一种食材信息编辑方法流程图，如图12所示，该方法可以包括：
S020，响应于输入的预设语音指令，判断当前显示的用户界面是否是食材编辑界面，所述食材编辑界面用于显示输入的食材信息；
S021，若当前显示的用户界面不是食材编辑界面，则显示标签扫描界面，所述标签扫描界面中显示扫描提示，所述扫描提示用于提示用户将待编辑的RFID标签放置在所述标签读取区；当检测到用户放置在标签读取区上的RFID标签时，根据所述预设语音指令包含的语音内容显示所述食材编辑界面；
S022，若当前显示的用户界面是食材编辑界面，根据所述预设语音指令包含的语音内容更新所述食材编辑界面。
在上述实施例中，用户可以先将待编辑的RFID标签放置在标签读取区上，此时，控制器检测到该RFID标签，显示食材编辑界面。然后用户通过说出预设语音口令，以输入预设语音指令，该预设语音指令包含用户要编辑的食材信息，比如说出“我要定义2斤牛肉”。在另一些实施例中，用户可以在将待编辑的RFID标签放置在标签读取区之前，说出预设语音口令，以输入预设语音指令，该预设语音指令用于触发编辑流程，还包括用户要编辑的食材信息，比如说出“我要定义2斤牛肉”。
由以上实施例可以看出，基于本申请实施例提供的食材信息编辑方法，用户可以通过语音输入，对RFID标签对应的食材信息进行编辑。具体的，当检测到用户放置在标签读取区上的RFID标签时，在显示食材编辑界面的同时，显示语音识别界面，即自动将语音应用切换到前台运行，从而快速进入到语音检测状态，及时检测用户的语音输入，用户通过说出想要编辑的食材信息，即可使冰箱自动完成信息输入过程，节省用户操作，且令编 辑过程更加快捷，提高用户体验。
图13为本申请根据示例性实施例示出的一种食材编辑界面，如图13所示，在该食材编辑界面上，显示有RFID标签的标识信息“20200005”，这样，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。还显示有多个输入项目，分别为食材名称输入项目410、食材保质期输入项目420和食材数量输入项目430，其中，每个食材输入项目对应有用于输入相应内容的输入位置。此外，还显示有“取消”控件440和“确定”控件450。信息输入完成后，用户可以点击“确定”控件，指示保存输入的食材信息，或者点击“取消”控件，指示返回到上一级界面。
在一些实施例中，控制器显示食材编辑界面的过程可以包括：首先根据待编辑标签的标识信息判断食材信息集合中是否存在对应的食材信息；若食材信息集合中存在对应的食材信息，则根据该食材信息在食材编辑界面中显示输入项目对应的输入内容；若食材信息集合中不存在对应的食材信息，则根据预置填充信息在食材编辑界面中显示编辑项目对应的项目内容。
在一个例子中，根据待编辑标签的标识信息判定食材信息集合中是否存在对应的食材信息，具体为：苹果、60天、1000g，显示的食材编辑界面如图14所示。参阅图14，该食材编辑界面中，“标签名称”对应的输入内容为“苹果”、“保质期”对应的输入内容为“60天”“数量”对应的输入内容为“1000g”。通过该食材编辑界面，用户可以获知待编辑标签在先关联的食材信息，还可以通过修改显示的输入内容，以输入新的食材信息。
在另一个例子中，根据待编辑标签的标识信息判定食材信息集合中不存在对应的食材信息，则显示的食材编辑界面如图15所示。参阅图15，该食材编辑界面中，“标签名称”、“保质期”、“数量”对应的输入内容均为预置填充字符“未定义”。通过该食材编辑界面，用户可以获知目标标签为全新标签，可以通过输入各编辑项目的内容，以输入用于与该待编辑标签进行关联的食材信息。
值得注意的是，在图13-图15所示食材编辑界面中，“保质期”和“数量”对应的输入位置处默认显示有计量单位。例如，在图13中，保质期的计量单位显示为“天”、数量的计量单位显示未“g”。在图14中，保质期的计量单位显示为“月”、数量的计量单位显示为“份”。以及在图15中，保质期的计量单位显示为“天”、数量的计量单位显示为“斤”。在显示食材编辑界面时，用户可以根据需求对保质期和/或食材数量的计量单位进行设置。例如，在显示如图13所示的食材管理界面时，用户可以点击计量单位旁的下拉控件，控制显示计量单位选项。
例如，在显示图13所示食材编辑界面时，用户可以点击保质期计量单位旁的下拉控件，控制保质期的计量单位选项弹出，如图16所示。保质期的计量单位选项弹出后，用户可以通过点击操作，选中要设置的计量单位，如在图16所示示例中，用户选中“月”后，计量单位选项收起，食材编辑界面中显示的计量单位由“天”变化为“月”。
例如，在显示图13所示食材编辑界面时，用户可以点击食材数量计量单位旁的下拉控件，控制食材数量的计量单位选项弹出，如图17所示。食材数量的计量单位选项弹出后，用户可以通过点击操作，选中要设置的计量单位，如在图17所示示例中，用户选中“份”后，计量单位选项收起，食材编辑界面中显示的计量单位由“g”变化为“份”。
在一些实施例中，在显示食材编辑界面时，用户可以通过语音口令，输入食材信息。语音口令中可以包括一个或者多个操作指令信息，如操作食材名称的指令信息、操作食材 保质期的指令信息以及操作食材数量的指令信息。一示例性的，在显示食材编辑界面时，如果用户说出：“定义2斤牛肉标签”，控制器则可以从该语音口令中解析出用于操作食材名称的指令信息和操作食材数量的指令信息。另一示例性的，在显示食材编辑界面时，如果用户说出：“定义保质期3个月”，控制器则可以从该语音口令中解析出用于操作食材保质期的指令信息。进而，控制器便可以根据解析出的指令信息输入相应项目对应的内容，显示在食材编辑界面中，而无需用户输入文字。这样，不但可以进一步减少用户操作，令编辑过程更加快捷，还可以提高该功能的普适程度，令不会打字的老人或小孩也可以完成食材信息的编辑。
在一些实施例中，当控制器检测到用户放置在标签读取区上的RFID标签时，在食材编辑界面中显示语音识别内容区，并开始接收、识别用户的语音口令，其中，语音识别内容区中可以显示输入提示和识别出的语音内容。在一些实施例中，食材编辑区域和语音识别内容区可以为两个不同视图显示区。不同的视图显示区可以是属于同一图层的区域，也可以是属于不同图层的区域。
图18为本申请在一些实施例中示出的一种包含语音识别内容区的食材编辑界面。如图18所示，语音识别内容区810显示在食材编辑界面的最上层，且与食材编辑区域820不重合。语音识别内容区810中显示有输入提示，具体为内容是“你可以说，我要定义2斤水蜜桃”的文字提示。当接收到用户输入的语音口令并识别出语音内容时，语音识别内容区中还可以显示识别出的语音内容。
在一些实施例中，控制器接收到用户输入的语音口令，将语音口令数据发送给服务器；服务器解析该语音口令数据得到对应的语音内容，根据语音内容生成语音指令信息，语音指令信息包括多个字段，一个字段对应一个食材输入项目，字段名称即为项目名称，字段值即为操作类型和/或操作数据。服务器将生成的语音指令信息返回给控制器，控制器根据语音指令信息中各字段的字段值对相应的输入项目进行操作，并显示相应输入项目的内容。
在一些实施例中，语音指令信息包括第一指令信息，第一指令信息用于操作食材保质期，第一指令信息中至少包括第一操作数据，第一操作数据包括第一操作数值和第一时间单位，该携带第一时间单位的第一操作数值是从语音口令中直接解析出的原始语音内容，如，如果用户输入的语音口令是“我要定义2斤牛肉，保质期3个月”，则携带第一时间单位的第一操作数值即为“3个月”。
在一些实施例中，控制器通过解析输入的语音口令，得到用于操作食材保质期的第一指令信息后，根据第一指令信息确定第二指令信息，第二指令信息包括目标操作类型和第二操作数据，第二操作数据包括第二操作数值和第二时间单位，该第二时间单位是预设时间单位中的一个。然后根据目标操作类型和第二操作数据，在食材编辑界面中显示食材保质期对应的输入内容。
在控制器在根据第一指令信息生成第二指令信息的过程中，首先判断第一时间单位是否是预设时间单位，同时判断第一操作数值是否为整数。如果第一时间单位是预设时间单位，并且第一操作数值是整数，则无需对第一指令信息中的操作数值及其单位进行处理，而是将第一时间单位确定为第二时间单位，将第一操作数值确定为第二操作数值。如果第一时间单位不是预设时间单位，或者第一操作数值不是整数，则需要对第一指令信息中的操作数值及其单位进行处理，具体是根据第一时间单位与预设时间单位之间的换算关系，将第一操作数值转换成以预设时间单位计的第二操作数值，且需保证第二操作数值为整数。
在一些可能的实现方式中，预设时间单位包括月和天。在第一时间单位为年或者月时，将第一操作数值转换成以月或者天计的第二操作数值；在第一时间单位为周或者天时，将第一操作数值转换成以天计的第二操作数值。具体来说，如果第一时间单位为年且第一操作数值是整数，如3年，则无需对其进行处理，直接以该携带第一时间单位的第一操作数值作为第二操作数值。如果第一时间单位为年且第一操作数值不是整数，如2.5年，则将该第一操作数值转换成以月计的第二操作数值，即2.5×12月。如果第一时间单位为月且第一操作数值是整数，如3个月，则无需对其进行处理，直接以该携带第一时间单位的第一操作数值作为第二操作数值。如果第一时间单位为月且第一操作数值不是整数，如2.5个月，则将该第一操作数值转换成以天计的第二操作数值，即为2.5×30天。如果第一时间单位为周(星期)，则由于周并非预设时间单位，因此无论第一操作数值是否为整数，都需要将该第一操作数值转换成以天计的第二操作数值，例如，需要将3周转换成3×7天。如果第一时间单位为天，且第一操作数值是整数，则无需对其进行处理。如果第一时间单位为天，且第一操作数值不是整数，将该第一操作数值向下取整得到仍以天计的第二操作数值，例如，将2.5天向下取整得到2天，将3.4天向下取整得到3天。
另外，值得注意的是，用户语音控制输入食材信息时，输入的语音口令中还可以包括操作食材保质期的操作类型，操作类型可以包括延长操作、缩短操作以及设置操作。应当理解，如果输入的语音口令中包含冰箱支持的操作类型，则通过解析语音口令所得到的第一指令信息中，自然包括操作类型。如果输入的语音口令中不包含冰箱支持的操作类型，则第一指令信息中不包括操作类型。例如，当在显示食材编辑界面时，如果用户说出“延长保质期3个月”时，该语音口令中包含的操作类型即为延长操作；如果用户说出“缩短保质期2个月”，该语音口令中包含的操作类型即为缩短操作；如果用户说出“定义保质期3个月”，该语音口令中包含的操作类型即为设置操作。
基于此，在控制器在根据第一指令信息生成第二指令信息的过程中，如果第一指令信息还包括操作类型，则将该操作类型确定为目标操作类型，如果第一指令信息中不包括操作类型，则将预设操作类型确定为目标操作类型。作为可能的实现方式，预设操作类型可以为设置操作。即，在第一指令信息中不包含操作类型时，将设置操作确定为目标操作类型。
控制器在根据目标操作类型和第二操作数据时，首先根据目标操作类型和第二操作数据确定显示数据，显示数据由显示数值和第二时间单位组成。控制器在得到以第二时间单位计的显示数值后，将携带第二时间单位的显示数值作为食材保质期对应的输入内容，显示在食材编辑界面中。这样，在食材编辑界面中显示的时间计量单位与用户语音口令中保质期的计量单位不一致时，不但可以完成对食材保质期的操作，并且冰箱会按照用户说出的时间计量单位进行显示，以提高用户体验。
具体的，在目标操作类型为设置操作时，将第二操作数值确定为显示数值。
在目标操作类型为延长操作时，将在先存储的保质期数值和第二操作数值分别转换成以中间时间单位计的第一中间值和第二中间值；将第一中间值与第二中间值相加，得到以中间时间单位计的中间和；将中间和转换成以第二时间单位计的显示数值。为节省计算量，可以将预设的存储时间单位作为中间计量单位，存储时间单位即是在先存储的保质期数值的单位。示例性的，存储时间单位为秒，在先存储的保质期数值为200000(秒)，第二操作数值为3(天)。按照前述确定显示数值的方式可知，在该示例中，需要将第二操作数 值3(天)转换成3×24×60×60(秒)，然后将其与在先存储的保质期数值200000相加，得到261200(秒)。最后，将261200(秒)转换成以天计的显示数值，并向下取整得到5天。
或者，根据第二时间单位与存储时间单位的换算关系，将在先存储的保质期数值转换成以第二时间单位计的数值后，再将其与第二操作数值相加，最后得到以第二时间单位计的显示数值。
在目标操作类型为缩短操作时，将在先存储的保质期数值和第二操作数值分别转换成以中间时间单位计的第一中间值和第二中间值；将第一中间值与第二中间值相减，得到以中间时间单位计的中间差；将中间差转换成以第二时间单位计的显示数值。示例性的，存储时间单位为秒，在先存储的保质期数值为200000(秒)，第二操作数值为3(天)。按照前述确定显示数值的方式可知，在以存储时间单位(秒)作为中间时间单位的情况下，需要将第二操作数值3(天)转换成3×24×60×60(秒)，然后将其与在先存储的保质期数值200000相减，得到59200(秒)。最后，将59200(秒)转换成以天计的显示数值，并向下取整得到0天。
或者，根据第二时间单位与存储时间单位的换算关系，将在先存储的保质期数值转换成以第二时间单位计的数值后，再将第二操作数值与其相减，最后得到以第二时间单位计的显示数值。
示例性的，在显示食材编辑界面时，响应于用户输入的语音口令“我要定义2斤牛肉，保质期3个月”，食材管理界面中标签名称对应的内容将显示为“牛肉”、食材保质期对应的内容将显示为“3月”、食材数量对应的内容将显示为“2斤”，如图19所示。
在将食材编辑界面中各个输入项目的内容输入完成后，用户可以通过点击食材编辑界面上的“确认”控件，以输入确认操作。控制器响应于接收到用户在食材编辑界面上输入的确认操作，将接收到的用户输入的食材信息与待编辑标签的标识信息对应保存在食材信息集合中。
在上述实施例中，在目标操作类型为缩短操作或者延长操作时，将第二操作数值转换成以存储时间单位计的第二中间值，一方面可以方便计算出显示数值，另一方面可以直接使用以存储时间单位计的中间和或者中间差，更新在先存储的保质期数值，以完成对保质期的缩短操作或者延长操作。而对于目标操作类型为设置操作的情形，则将第二操作数值(或者说显示数值)转换成以存储时间单位计的保质期数值，并将该保质期数值保存在食材信息中。
此外，控制器还响应于该确认操作，撤销食材编辑界面，显示食材管理界面，并根据输入的食材信息更新食材管理界面。例如，更新后的食材管理界面中新增有根据输入的食材信息生成的食材图标。
应理解的是，相比于更新前的食材管理界面，一些更新后的食材管理界面中会显示出新的食材图标，即为新增食材对应的食材图标；一些更新后的食材管理界面中，由于一些食材的保质期被延长或者缩短，因此一些食材图标的新鲜度标识得到更新。
由以上实施例可知，基于本申请实施例提供的冰箱，可以在用户通过语音口令操作食材保质期时，通过解析语音口令，得到用于操作食材保质期的目标操作类型和第一操作数据，第一操作数据包括第一操作数值和第一时间单位。之后确定第一操作数据对应的第二操作数据，第二操作数据包括第二操作数值和第二时间单位，第二时间单位为预设时间单 位。最后根据目标操作类型和第二操作数据，对食材保质期进行操作，以及在食材编辑界面中显示食材保质期对应的输入内容。从而，即使语音口令中的时间单位与预设时间单位不符，也可以完成对食材保质期的操作，提高用户体验。
在一些实施例中，控制器接收到用户输入的语音口令，将语音口令数据发送给服务器；服务器解析该语音口令数据得到对应的语音内容，根据语音内容生成语音指令信息，语音指令信息包括多个字段，一个字段对应一个食材输入项目，字段名称即为项目名称，字段值即为操作类型和/或操作数据。服务器将生成的语音指令信息返回给控制器，控制器根据语音指令信息中各字段的字段值对相应的输入项目进行操作，并显示相应输入项目的内容。
在一些实施例中，控制器通过解析输入的语音口令，得到用于操作食材数量的指令信息，所述指令信息包括操作类型和目标操作数据，目标操作数据包括目标操作数值和目标计量单位。该携带目标计量单位的目标操作数值是从语音口令中直接解析出的原始语音内容，如，如果用户输入的语音口令是“我要定义2斤牛肉”，则携带目标计量单位的目标操作数值即为“2斤”。作为可能的实现方式，对食材数量的操作包括输入操作和修改操作，输入操作是在未在先存储的食材数量的情况下，对语音口令中指示的目标操作数值进行存储；修改操作则是指在先存储的食材数量的情况下，根据语音口令中指示的目标操作数值对在先存储的食材数量进行增加或者减少操作。
值得注意的是，在一些实现方式中，控制器通过服务器解析输入的语音口令，服务器从语音口令中解析出语音内容，将语音内容返回给冰箱控制器。冰箱控制器再根据服务器返回的语音内容，确定用于操作食材数量的指令信息。在另一些实现方式中，控制器通过服务器解析输入的语音口令，服务器从语音口令中解析出语音内容，并根据语音内容确定用于操作食材数量的指令信息，将指令信息返回给冰箱控制器。其中，语音内容包括携带目标计量单位的目标操作数值。
在上述实现方式中，服务器或者冰箱控制器从语音口令中解析出目标计量单位和目标操作数值后，判断目标计量单位是否为预设计量单位，以及目标操作数值是否落在目标计量单位预设的允许操作范围内；如果目标计量单位是预设计量单位，且目标操作数值落在允许操作范围内，则得到包含目标操作数值和目标计量单位的目标操作数据。如果目标计量单位不是预设计量单位，或者目标操作数值未落在允许操作范围内，则结束流程。示例性的，预设计量单位可以分为重量计量单位、单数计量单位和复数计量单位。其中，重量计量单位可以包括千克、克、斤，单位计量单位可以包括把、份、个、块、条、瓶、根、只、颗、片、串、盘、听、杯、罐等，复数计量单位可以包括袋、包、盒等。
需要说明的是，在用户输入的语音口令中包含操作类型信息时，服务器可以从中解析出操作类型信息，在用户输入的语音口令中不包含操作类型信息时，服务器则无法从中解析出操作类型信息。若服务器未能从语音口令中解析出操作类型信息，或者解析出的操作类型不是冰箱控制器支持的操作类型，则将输入操作作为目标操作，以确定表征输入操作的操作类型。
控制器根据控制器通过解析输入的语音口令，得到用于操作食材数量的指令信息后，根据该指令信息中的操作类型和目标操作数据，确定以目标计量单位的目标显示数值，并将目标显示数值和目标计量单位作为食材数量对应的输入内容，显示在食材编辑界面中。其中，确定目标显示数值的步骤具体可以包括：
在操作类型表征输入操作时，将指令信息中的目标操作数值确定为目标显示数值。例 如，用户输入的语音口令为“我要定义2斤牛肉”，根据该语音口令可知，操作类型为输入操作，目标操作数值为2，目标计量单位为斤。在该示例中，目标显示数值为目标操作数值，即2。这样，即使在食材编辑界面中显示的数量计量单位与用户语音口令中的数量计量单位不一致，也可以完成对食材数量的输入操作，用户无需按照显示的数量计量单位输入语音口令，只需说出的数量计量单位是预设计量单位即可。而冰箱则会在用户说出的数量计量单位与当前默认显示的计量单位不一致时，按照用户说出的数量计量单位进行显示，以提高用户体验。
在操作类型表征修改操作时，首先判断目标计量单位与在先存储的计量单位的类别是否匹配。其中，在先存储的计量单位即为在先存储的食材数量的计量单位。在目标计量单位与在先存储的计量单位类别匹配的情况下，如果操作类型表征增加操作，则将在先存储的食材数量值与目标操作数值的加和确定为目标显示数值；如果操作类型表征减少操作，将在先存储的食材数量值与目标操作数值的差值确定为目标显示数值。这样，在用户通过语音控制修改在先存储的食材数量时，只需要用户语音口令中的数量计量单位与在先存储的计量单位类别匹配，即可完成修改操作，而无需用户语音口令中的数量计量单位与在先存储的计量单位完全一致。而冰箱则会在用户说出的数量计量单位与当前默认显示的计量单位不一致时，按照用户说出的数量计量单位进行显示，以提高用户体验。反之，如果目标计量单位与在先存储的计量单位类别不匹配，则在食材编辑界面的上层显示预定提示信息，以提示用户无法根据输入的语音口令操作食材保质期。
在一些实现方式中，控制器判断目标计量单位和在先存储的计量单位是否均为重量单位、单数计量单位或者复数计量单位；若目标计量单位和在先存储的计量单位均为重量单位、单数计量单位或者复数计量单位，则确定目标计量单位和在先存储的计量单位的类别匹配。在一个例子中，输入的语音口令为“我要定义5袋牛肉”，即目标计量单位为“袋”，在先存储的计量单位为“斤”，属于重量计量单位。在该示例中，由于“袋”属于复数计量单位，而“斤”属于重量计量单位，因此二者的类别不匹配。因此，需要在食材编辑界面上显示如图20中示出的提示信息，具体为“由于计量单位不匹配，无法完成当前操作”。
值得注意的是，在目标计量单位和在先存储的计量单位均为重量单位的情形中，控制器确定目标显示数值的步骤，具体可以包括：判断目标计量单位和在先存储的计量单位是否一致；在目标计量单位和在先存储的计量单位不一致时，将在先存储的食材数量转换成以目标计量单位计量的中间数值；最后根据目标操作数值和中间数值确定目标显示数值，即，如果操作类型表征增加操作，则将该中间数值与目标操作数值的加和确定为目标显示数值，如果操作类型表征减少操作，则将该中间数值与目标操作数值的差值确定为目标显示数值。
示例性的，在显示食材编辑界面时，响应于用户输入的语音口令“我要定义2斤牛肉，保质期3个月”，食材管理界面中标签名称对应的内容将显示为“牛肉”、食材保质期对应的内容将显示为“3月”、食材数量对应的内容将显示为“2斤”，如图21所示。
在将食材编辑界面中各个输入项目的内容输入完成后，用户可以通过点击食材编辑界面上的“确认”控件，以输入确认操作。控制器响应于接收到该确认操作，将接收到的用户输入的食材信息与待编辑标签的标识信息对应保存在食材信息集合中。其中，在对食材数量的操作为输入操作时，将携带目标计量单位的目标显示数值作为食材信息中的一项，保存在食材信息集合中。在对食材数量的操作为修改操作时，则使用目标显示数值和目标 计量单位更新在先存储的食材数量值和计量单位。
此外，控制器还响应于该确认操作，撤销食材编辑界面，显示食材管理界面，并根据输入的食材信息更新食材管理界面。例如，更新后的食材管理界面中新增有根据输入的食材信息生成的食材图标。
由以上实施例可知，基于本申请实施例提供的冰箱，在显示食材编辑界面时，用户可以通过输入语音口令，输入或者修改食材数量。其中，在通过语音控制输入食材数量时，即使在食材编辑界面中显示的数量计量单位与用户语音口令中的数量计量单位不一致，也可以完成输入操作，用户无需按照显示的数量计量单位输入语音口令，只需说出的数量计量单位是预设计量单位即可。在通过语音控制修改在先存储的食材数量时，只需要用户语音口令中的数量计量单位与在先存储的计量单位类别匹配，即可完成修改操作，而无需用户语音口令中的数量计量单位与在先存储的计量单位完全一致。而冰箱则会在用户说出的数量计量单位与当前默认显示的计量单位不一致时，按照用户说出的数量计量单位进行显示，以提高用户体验。
本申请实施例还提供一种语音控制方法，该方法的执行主体包括但不限于冰箱的控制器。示例性地，当电视与冰箱通过云端互联时，电视可以通过云端服务器查看和编辑冰箱内的食材，如打开智能家居相关的应用程序。在电视上编辑食材可以通过预先安装的语音助手进行对食材的编辑，也可以是控制器按键或者触控等方式。当电视对食材进行编辑后，也通过云端同步到冰箱上。
