Description

用于检测母乳新鲜度的方法及冷藏设备、存储介质
本申请基于申请号为202210890074.1、申请日为2022年7月27日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及冷藏设备技术领域，例如涉及一种用于检测母乳新鲜度的方法及冷藏设备、存储介质。
背景技术
目前，母乳为新生婴儿以及低龄幼儿主要的食物来源。在婴幼儿母亲的乳汁充足的情况下，会将部分母乳存储至冰箱中储存。母乳在低温环境中变质的速率放缓，用户可通过冷藏母乳的方式实现母乳的保鲜。然而，母乳在长时间冷藏存放后，母乳会发生变质。若误将变质后的母乳喂养婴幼儿，则会导致婴幼儿腹泻，甚至出现发烧等严重不良反应。为此，如何识别冷藏母乳的新鲜度，成为当前亟需解决的技术难题。
针对以上问题，相关技术公开一种母乳存储冷藏箱，包括箱体、设置于箱体外侧的制冷装置和控制器。控制器配置有用于对奶瓶进行计时的定时器。控制器用于通过定时器获取奶瓶的存储时间，并在存储时间达到设定的逾期存放时间时，通过控制器所电连接的显示屏进行提醒，以区分新鲜母乳和逾期母乳。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
相关技术通过母乳的存储时间间接判定母乳的新鲜度，然而，存储时间无法准确地反映母乳的新鲜程度。因此，相关技术采用的母乳新鲜度判别方法，准确性较差。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。
本公开实施例提供了一种用于检测母乳新鲜度的方法、冷藏设备和存储介质，以提升母乳新鲜度判别的准确性。
在一些实施例中，所述方法应用于冷藏设备，所述冷藏设备配置有冷藏室，所述冷藏 室存储有容置母乳的储存装置，其特征在于，所述储存装置贴附有电子标签，所述方法包括：通过所述电子标签获取母乳的介电特性相关联的电信号；根据所述电信号，确定所述母乳的新鲜度。
在一些实施例中，所述冷藏设备包括：冷藏室；储存装置，容置有母乳，被存储于所述冷藏室；电子标签，贴附于所述储存装置，用于获取母乳的介电特性相关联的电信号；处理器，与所述电子标签电连接，用于根据所述电信号，确定所述母乳的新鲜度。
在一些实施例中，所述冷藏设备，包括处理器和存储有程序指令的存储器，所述处理器被配置为在运行所述程序指令时，执行如前述的用于检测母乳新鲜度的方法。
在一些实施例中，所述存储介质，存储有程序指令，所述程序指令在运行时，执行如前述的用于检测母乳新鲜度的方法。
本公开实施例提供的用于检测母乳新鲜度的方法、冷藏设备和存储介质，可以实现以下技术效果：
母乳变质由母乳中的微生物对乳汁中的成分进行新陈代谢导致，在微生物新陈代谢过程中，母乳中的导电粒子发生改变。即母乳的介电特性可以反映出母乳的新鲜度。本公开实施例通过电子标签获取与母乳的介电特性相关联的电信号，可将介电特性转换为电信号，从而以电信号的形式确定出母乳的新鲜度，提升了母乳新鲜度判别的准确性。此外，本公开实施例通过在储存装置贴附电子标签的方式进行母乳的新鲜度的判别，实现了母乳新鲜度的无损检测。
以上的总体描述和下文中的描述仅是示例性和解释性的，不用于限制本申请。

母乳为新生婴儿以及低龄幼儿主要的食物来源。母乳在长时间冷藏存放后，母乳会发生变质。若误将变质后的母乳喂养婴幼儿，则会导致婴幼儿腹泻，甚至出现发烧等严重不良反应。为此，如何识别冷藏母乳的新鲜度，成为当前亟需解决的技术难题。
针对以上问题，相关技术公开一种母乳存储冷藏箱，包括箱体、设置于箱体外侧的制冷装置和控制器。控制器配置有用于对奶瓶进行计时的定时器。控制器用于通过定时器获取奶瓶的存储时间，并在存储时间达到设定的逾期存放时间时，通过控制器所电连接的显示屏进行提醒，以区分新鲜母乳和逾期母乳。
相关技术通过母乳的存储时间间接判定母乳的新鲜度，然而，存储时间无法准确地反映母乳的新鲜程度。因此，相关技术采用的母乳新鲜度判别方法，准确性较差。
本公开实施例提供一种冷藏设备，配置有冷藏室、处理器以及RFID(Radio Frequency Identification，射频识别)阅读器。冷藏室存储有容置母乳的储存装置。储存装置贴附有电子标签。电子标签包括射频识别RFID标签以及RFID天线。RFID标签与RFID天线通信连接。RFID阅读器通过RFID天线与RFID标签通信连接。处理器与RFID阅读器电连接。其中，冷藏设备包括冰箱、冰柜等具备冷藏功能的制冷设备。
基于上述冷藏设备，结合图1所示，本公开实施例提供一种用于检测母乳新鲜度的方法，包括：
S01，处理器通过电子标签获取母乳的介电特性相关联的电信号。
S02，处理器根据电信号，确定母乳的新鲜度。
采用本公开实施例提供的用于检测母乳新鲜度的方法，母乳变质由母乳中的微生物对乳汁中的成分进行新陈代谢导致，在微生物新陈代谢过程中，母乳中的导电粒子发生改变。即母乳的介电特性可以反映出母乳的新鲜度。本公开实施例通过电子标签获取与母乳的介电特性相关联的电信号，可将介电特性转换为电信号，从而以电信号的形式确定出母乳的新鲜度，提升了母乳新鲜度判别的准确性。此外，本公开实施例通过在储存装置贴附电子标签的方式进行母乳的新鲜度的判别，实现了母乳新鲜度的无损检测。
图5表示母乳与水各自的介电特性相关联的射频信号对应的谐振频率的变化量在时间维度上的变化曲线图。结合图5所示，在储存装置存储有水的情况下，由于水在时间维度上介电特性不变，所以，射频信号对应的谐振频率的变化量保持数值零。在储存装置存储有母乳的情况下，由于母乳在时间维度上介电特性改变，射频信号对应的谐振频率的变化量在0～35h的时间段上呈增大趋势，在35h～45h的时间段上增大趋势逐步放缓。根据图5可知，谐振频率的变化量随着母乳的介电特性的变化逐步增大。增大趋势大致为先呈快速增大趋势，增大至某峰值后缓慢增大，最终，基本保持。
结合图2所示，处理器通过电子标签获取母乳的介电特性相关联的电信号，包括：
S11，处理器利用RFID标签读取介电特性相关联的射频信号。
S12，处理器通过RFID阅读器解析射频信号，确定射频信号相对应的谐振频率，以根据谐振频率确定母乳的新鲜度。
这样，本公开实施例通过RFID标签读取介电特性相关联的射频信号，再通过RFID阅读器解析射频信号，以确定出与射频信号相对应的谐振频率。最后，通过谐振频率判别母乳的新鲜度。由此，有利于提升母乳新鲜度判别的准确性。
可选地，处理器通过RFID标签读取介电特性相关联的射频信号，包括：
处理器间隔读取介电特性相关联的射频信号。
其中，处理器间隔读取介电特性相关联的射频信号，可以为根据预设周期，周期性获取射频信号。预设周期数值可以根据实际需求确定。作为一种示例，预设周期为20分钟，30分钟，或者1小时等数值。可以理解地，预设周期数值越小，母乳新鲜度判别的准确性越高。
处理器确定射频信号相对应的谐振频率，包括：
处理器解析间隔读取的射频信号，确定各射频信号对应的谐振频率。
这样，由于母乳的介电特性随时间发生改变，所以，本公开实施例通过读取母乳的介电特性相关联的射频信号后，解析间隔读取的射频信号以确定各射频信号对应的谐振频率，以根据各谐振频率来判别母乳的新鲜度。由此，本公开实施例通过将介电特性转换为射频信号，解析射频信号后确定出谐振频率后根据谐振频率确定母乳的新鲜度，有效地提升了母乳新鲜度判别的准确性。与此同时，本公开实施例有利于进行母乳新鲜度的无损检测。
可选地，结合图3所示，处理器根据电信号，确定母乳的新鲜度，包括：
S21，处理器根据各射频信号对应的谐振频率，计算相邻时刻下的谐振频率的变化量。
S22，处理器根据多个谐振频率的变化量，确定母乳的新鲜度。
这样，由于谐振频率的变化量随着母乳的介电特性的变化逐步增大，因此，本公开实施例根据多个谐振频率的变化量进行母乳新鲜度的判别，既能够提升母乳新鲜度判别的准确性，又降低了母乳新鲜度计算的复杂性。
可选地，处理器根据多个谐振频率的变化量，确定母乳的新鲜度，包括：
在多个谐振频率的变化量大于或者等于预设频率值的情况下，确定母乳变质。
其中，谐振频率的变化量表示当前时刻的谐振频率与上一时刻的谐振频率的差值的绝对值。
这样，经实验获知，母乳在变质的情况下，介电特性发生较大改变。相应地，射频信号以及经解析获得的谐振频率的变化量将高于或者等于预设频率值。因此，本公开实施例将谐振频率的变化量与预设频率值进行比较，并在谐振频率的变化量大于或者等于预设频率值时，确定母乳变质。
需要说明的是，处理器根据多个谐振频率的变化量，确定母乳的新鲜度，还包括：
在谐振频率的变化量小于预设频率值的情况下，确定母乳新鲜。
结合图4所示，本公开实施例还提供一种用于检测母乳新鲜度的方法，包括：
S31，处理器通过RFID标签间隔读取介电特性相关联的射频信号。
S32，处理器通过RFID阅读器解析间隔读取的射频信号，确定各射频信号对应的谐振频率。
S33，处理器根据各射频信号对应的谐振频率，计算相邻时刻下的谐振频率的变化量。
S34，处理器在谐振频率的变化量大于或者等于预设频率值的情况下，确定母乳变质。
S35，处理器推送母乳的新鲜度相关联的提示信息。
采用本公开实施例提供的用于检测母乳新鲜度的方法，处理器在谐振频率的变化量大于或者等于预设频率值的情况下，推送母乳的新鲜度相关联的提示信息，以使用户实时获知母乳的新鲜度。避免将已变质的母乳作为安全食物喂养婴幼儿而出现不适症状。本公开实施例提升了母乳新鲜度提醒的实时性。
可选地，提示信息可以为音频信息、文字信息、图像信息或者振动信息中的一个或者多个。作为一种示例，冷藏设备与终端设备通信连接。处理器在谐振频率的变化量大于或者等于预设频率值的情况下，推送携带有“母乳变质”的文字信息至终端设备，以使携带终端设备的用户获知母乳的新鲜度。作为另一种示例，冷藏设备配置有显示屏，处理器在谐振频率的变化量大于或者等于预设频率值的情况下，通过显示屏显示携带有“母乳变质”的图像信息，以使用户获知母乳的新鲜度。关于提示信息的提示方式，本公开实施例对此可不做具体限定。
本公开实施例还提供一种冷藏设备，包括冷藏室、存储装置、电子标签以及处理器。储存装置，容置有母乳，被存储于冷藏室。电子标签贴附于储存装置，用于获取母乳的介电特性相关联的电信号。处理器与电子标签电连接，用于根据电信号，确定母乳的新鲜度。
采用本公开实施例提供的冷藏设备，本公开实施例通过电子标签获取与母乳的介电特性相关联的电信号，可将介电特性转换为电信号，从而以电信号的形式确定出母乳的新鲜度，提升了母乳新鲜度判别的准确性。此外，本公开实施例通过在储存装置贴附电子标签的方式进行母乳的新鲜度的判别，实现了母乳新鲜度的无损检测。
可选地，电子标签包括RFID标签、RFID天线。RFID标签，用于采集母乳的介电特性相关联的射频信号。冷藏设备还配置有RFID阅读器。RFID阅读器通过RFID天线与RFID标签通信连接。处理器还用于读取射频信号，并通过RFID阅读器解析射频信号，确定射频信号相对应的谐振频率，以根据谐振频率确定母乳的新鲜度。
这样，有利于提升母乳新鲜度判别的准确性。
在实际应用中，用于检测母乳新鲜度的方法具体执行以下步骤：
S41，处理器通过RFID标签以预设周期ΔT间隔读取母乳的介电特性相关联的射频信号，并通过RFID阅读器解析各射频信号，确定各射频信号T0时刻相对应的谐振频率f0，并记录射频信号T0+ΔT时刻相对应的谐振频率f1。
S42，处理器记录谐振频率变化量为Δf＝|f1-f0|。
S43，处理器将Δf与预设频率值比较，经判断，谐振频率变化量大于预设频率值。由此，判定母乳已变质。
S44，处理器通过显示屏显示携带有“母乳变质”的图像信息。
