Therefore, the state change speed of the free water inside the food is faster than in the later stage of thawing, making the frequency of mismatch of the initial tuning loop higher than in the later stage of thawing. Therefore, the initial mismatch frequency is the maximum mismatch frequency in the entire thawing process of the food to be thawed.

如图2所示，为本公开提供的一种具有射频解冻功能的冰箱系统示意图，如图2所示，该冰箱系统可以包括解冻控制系统和冰箱控制系统。
解冻控制系统包括硬件系统和控制系统，硬件系统包括可调电源201，用于为整个制冷设备提供电源，并且可实现输出电压调节功能；射频功率放大回路202，用于向调谐回路203输出射频功率，同时向食材解冻过程提供射频解冻能量；调谐回路203，用于补偿食材状态变化导致的负载阻抗不匹配；以及解冻腔体204，用于容纳待解冻的食材。

在一些实施例中，解冻控制系统还可以包括第一通信接口208，用于和冰箱控制系统进行数据通信。
如图2所示，冰箱控制系统还可以包括第二通信接口209、传感器组210、以及主控制器211。第二通信接口209用于和解冻控制系统进行通信。传感器组210包括一个或多个传感器，用于获取待解冻食材的食材信息。主控制器211用于对射频解冻参数进行估算。
传感器组210中可以包括N个传感器，N为正整数，传感器的种类可以包括但不限于NFC(Near Field Communication，近场通信)感应器、图像采集装置、温度传感器、状态检测传感器、红外传感器。针对制冷设备中每种传感器的设置数量，可以根据实际需要进行选择，这里不做限定。
步骤S101中，待解冻食材的目标食材信息包括但不限于食材类型、食 材质量以及食材初始温度。在一些实施例中，食材类型包括但不限于食材的含脂率、含水率以及食材的具体种类。由于制冷设备中设置有N个传感器，根据传感器的类型不同，获取待解冻食材的目标食材信息的方式也会存在差别，下面，分别以传感器为NFC感应器、图像采集装置、以及状态检测传感器为例，来对目标食材信息的获取过程进行说明。
一、传感器为NFC感应器。
在一些实施例中，可以通过以下步骤来获取目标食材信息：通过所述NFC感应器对所述待解冻食材进行检测；若检测到所述待解冻食材上设置有NFC标签，获取所述NFC感应器从所述NFC标签中读取到的所述待解冻食材的食材类型以及食材质量。
NFC感应器可以是设置在制冷设备上的，例如，以制冷设备为带有射频解冻装置的冰箱为例，冰箱上设置有NFC感应器。若待解冻食材上设置有NFC标签，只需要通过NFC感应器对NFC标签进行扫描，即可读取待解冻食材的食材类型、食材质量以及其他信息。或者，NFC感应器可以为用户终端上的NFC感应器，例如，用户通过具有NFC功能的手机对待解冻食材上的NFC标签进行扫描，然后，将扫描得到的待解冻食材的食材类型以及食材质量等信息发送给制冷设备。
对于每个待解冻食材，均可以预先分配各自的NFC标签，例如，对于待解冻食材A，可以通过用户终端或者制冷设备向食材A的NFC标签内写入食材A的类型以及质量等信息，然后将写好数据的NFC标签绑在食材A上。
以上述具有射频解冻功能的冰箱系统为例，若待解冻食材上设置有NFC标签，可以通过冰箱上的NFC感应器对NFC标签进行扫描，读取待解冻食材的食材类型以及质量等信息，当检测到将待解冻食材放入解冻腔体后，解控控制系统以及根据获取到的待解冻食材的具体信息进行精准的解冻控制。
二、传感器为图像采集装置。
在一些实施例中，可以通过以下步骤来获取目标食材信息：通过所述图像采集装置对所述待解冻食材进行图像扫描；若扫描结果表明所述待解冻食材上设置有图形码标签，从所述图形码标签中提取出目标食材标识，并从食材录入信息库中确定出与所述目标食材标识对应的目标录入信息；所述食材录入信息库中包括食材标识与录入的食材类型、食材质量之间的对应关系。
图像采集装置可以设置在制冷设备上，例如，以制冷设备为带有射频解冻装置的冰箱为例，冰箱上设置有图像采集装置。若待解冻食材上设置有图形码标签，如二维码、条形码等，则可以通过图像采集装置对图形码标签进行扫描并解析，得到图形码对应的目标食材标识。
针对每个图形码对应的食材标识，均可以预先在系统中录入与每个食材标识对应的食材类型、食材质量等信息，即建立食材标识与食材类型、食材指令等信息之间的对应关系，以形成食材录入信息库。在通过扫描待解冻食 材的图形码标签，得到目标食材标识后，通过查询食材录入信息库即可得到待解冻食材的食材类型、食材质量等信息。
在一些实施例中，图形码中也可以直接包含有食材类型、食材质量等信息，通过解析图形码就可以直接获取对应食材的食材信息，这里不做限定。
在一些实施例中，对于每个待解冻食材来说，可以预先将对应的图形码标签贴在待解冻食材上，在对待解冻食材解冻时，只需要通过图像采集装置对图形码标签进行扫描，即可得到对应的食材类型、食材质量等信息。
三、传感器包括NFC感应器和图像采集装置
在一些实施例中，可以通过以下步骤来获取目标食材信息：通过所述NFC感应器和所述图像采集装置对所述待解冻食材进行扫描；若所述NFC感应器未扫描到NFC标签，且所述图像采集装置未扫描到图形码标签，通过所述图像采集装置获取所述待解冻食材的目标图像，所述目标图像包含有所述待解冻食材的完整图像信息；对所述目标图像进行图像识别，确定所述待解冻食材的食材类型以及食材体积；基于所述待解冻食材的食材体积，确定所述待解冻食材的食材质量。
制冷设备中可以同时设置有NFC感应器和图像采集装置，NFC感应器可以用于对待解冻食材上的NFC标签进行扫描，图像采集装置可以用于对待解冻食材上的图形码进行扫描。
在一些实施例中，若NFC感应器没有感应到NFC标签，图像采集装置也没有扫描到图形码标签，则可以对食材的种类和质量进行估算。在对待解冻食材的信息进行估算时，可以通过图像采集装置获取包括待解冻食材完整图像信息的目标图像，再对目标图像进行图像识别。在一些实施例中，可以预先训练好图像识别模型，图像识别模型可以为卷积神经网络模型或其他类型的模型，这里不做限定。在得到目标图像之后，将目标图像输入到图像识别模型中，以输出待解冻食材的食材类型。最终输出的食材类型可以为待解冻食材所属的食材大类，例如：蔬菜类、水果类、肉类等，还可以是具体的食材种类，例如：苹果、西蓝花、肉等，这里不做限定。
在估算待解冻食材的质量时，可以先通过对目标图像进行处理，确定出待解冻食材在目标图像中的尺寸，再基于图像坐标系与世界坐标系之间的对应关系，将待解冻食材对应的图像中的尺寸转换成世界坐标下的真实尺寸，从而得到待解冻食材的体积。在通过图像识别得到待解冻食材的食材类型之后，还可以通过食材类型与食材密度之间的预设对应关系，确定出待解冻食材的密度，然后再基于待解冻食材的密度和体积，估算出待解冻食材的质量。
四、传感器为状态传感器。
在一些实施例中，制冷设备中可以包括多个食材存储腔体，每个食材存储腔体设置有对应的存储温度，通过状态传感器确定目标食材信息可以通过以下步骤实现：若所述状态传感器检测到目标存储腔体由闭合状态切换为打 开状态，确定所述目标存储腔体对应的目标存储温度，并将所述目标存储温度作为所述待解冻食材的初始温度。
以制冷设备为带有射频解冻装置的冰箱为例，冰箱内可以设置有多个食材存储腔体，食材存储腔体可以是独立的用于分类存储的抽屉，针对每个食材存储腔体，均可以对应有各自的存储温度。在一些实施例中，存储温度可以是用户自行设置的，也可以是系统默认的温度。对于不同的食材存储腔体来说，存储温度可以相同也可以不同，这里不做限定。
在对待解冻食材进行解冻之前，需要将待解冻食材从对应的存储腔体中取出，然后放入解冻腔体。因此，可以通过状态传感器检测在解冻之前哪个存储腔体被打开过，并将打开的存储腔体作为目标存储腔体，从而将目标存储腔体对应的目标存储温度作为待解冻食材的初始温度。
为了准确确定待解冻食材对应的目标存储腔体，在检测到存储腔体被打开时，可以通过图像采集装置采集从被打开腔体中取出的食材的图像信息，同时，采集解冻腔体中放入的食材的图像信息。在一些实施例中，如果检测到多个存储腔体被打开，则得到与每个存储腔体对应的食材图像信息，分别与解冻腔体中放入的食材的图像信息进行匹配，并将匹配成功的食材图像信息对应的存储腔体作为目标存储腔体。
上述不同种类的传感器可以根据实际需要进行组合，这里不做限定。
步骤S102中，在获取到待解冻食材的目标食材信息后，确定与目标食材信息对应的射频解冻参数。射频解冻参数可以通过多种方式实现，例如，可以预先设置好食材信息与射频解冻参数之间的对应关系，在确定了目标食材信息之后，通过查询该对应关系即可得到与目标食材信息对应的射频解冻参数。
在一些实施例中，步骤S102可以为：基于所述目标食材信息，确定所述射频解冻装置的目标射频解冻功率和初始解冻时长，步骤S103可以为：在所述目标射频解冻功率下，按照所述初始解冻时长，控制所述射频解冻装置对所述食材进行解冻。
目标射频解冻功率和初始解冻时长可以通过多种实现。在一些实施例中，针对每种食材类型，可以预先设置好与该食材类型对应的射频解冻功率以及初始解冻时长，在确定了待解冻食材的目标类型后，通过查询预先设置好的对应关系，即可得到目标射频解冻功率以及初始解冻时长。
在一些实施例中，目标射频解冻功率以及初始解冻时长可以通过以下步骤来获取：基于所述待解冻食材的初始温度以及预设的目标温度，确定所述待解冻食材解冻前后的目标温差；基于所述目标温差、所述待解冻食材的比热容、以及所述待解冻食材的食材质量，确定对所述待解冻食材对行解冻的目标能量；基于所述待解冻食材的食材类型，确定用于对所述待解冻食材进行解冻的目标解冻模式，并基于所述目标解冻模式，确定所述目标射频解冻 功率；基于所述目标能量、所述目标射频解冻功率以及所述待解冻食材吸收能量的效率，确定所述待解冻食材的初始解冻时长。
制冷设备可以预设有多个解冻模式，例如，针对不同的食材预设有多个解冻模式，如猪肉解冻模式、鱼类解冻模式、虾类解冻模式等。针对每个解冻模式，配置有各自的射频解冻功率。每个模式下的射频解冻功率可以是固定值，也可以是射频解冻功率变化曲线。当射频解冻功率为射频解冻功率变化曲线时，可以使待解冻食材在不同解冻阶段吸收不同的射频功率，一方面可以避免射频能量的浪费，另一方面可以提高射频解冻装置为食材解冻匹配的解冻方案的准确性。
在一些实施例中，基于制冷设备的传感器识别出待解冻食材的食材类型之后，确定与该食材类型对应的目标解冻模式，并将目标解冻模式对应的射频解冻功率作为目标射频解冻功率。
在确定初始解冻时长时，可以先确定待解冻食材在解冻过程中所需要的目标能量。在一些实施例中，根据待解冻食材的初始温度以及预设的目标温度，计算待解冻食材在解冻前后的目标温差。目标温度可以为待解冻食材的解冻后温度，解冻后的目标温度范围可以为-5°～0°，目标温度可以根据实际需要进行设置，这里不做限定。将目标温度和初始温度之间的差值作为目标温差。在一些实施例中，可以根据待解冻食材的食材类型，通过查询预设的食材类型与比热容之间的对应关系，确定待解冻食材的比热容。
待解冻食材解冻所需的目标能量可以通过以下公式来计算：
Q＝mct
Q为解冻所需的目标能量，m为待解冻食材的质量，c为待解冻食材的比热容，t为待解冻食材的目标温差。
初始解冻时长可以通过以下公式来确定：
T＝Q/pη
T为初始解冻时长，p为目标射频解冻功率，η为待解冻食材吸收能量的效率，η可以为一固定值，例如80％、85％等，η也可以根据待解冻食材的不同而变化，例如，预先设置好不同食材与η之间的对应关系，通过查询对应关系来确定η最终的取值。
步骤S103中，在得到针对待解冻食材的射频解冻参数后，控制射频解冻装置以射频解冻参数运行，以对待解冻食材进行解冻。以射频解冻装置为例，在得到了目标射频解冻功率和初始解冻时长后，可以根据目标射频解冻功率和初始解冻时长对待解冻食材进行解冻。
考虑到解冻过程中，待解冻食材的状态时不断变换的，因此，待解冻食材的实际解冻时长有可能与初始解冻时长不匹配，如果仅采用初始解冻时长进行解冻，而不对待解冻食材的解冻时长进行控制，则有可能会出现过度解冻或解冻不充分的问题发生。
基于此，针对待解冻食材，在一些实施例中，还可以计算待解冻食材的理论解冻时长，并基于理论解冻时长与初始解冻时长之间的关系，来确定对待解冻食材的最终解冻时长。
理论解冻时长可以通过多种方式确定，下面，对其中的两种确定理论解冻时长的实现方式进行说明。
第一种实现方式：
获取所述调谐回路在所述初始解冻时长初期的失配频率，作为初始失配频率，所述失配频率用于表征所述调谐回路被触发进行阻抗匹配的频繁程度；确定所述调谐回路在所述待解冻食材发生相变时的失配频率，作为参考失配频率，并获取所述调谐回路从所述初始失配频率变化至所述参考失配频率的实际消耗时长；基于所述初始失配频率和所述参考失配频率，以及所述实际消耗时长，确定所述射频解冻装置解冻所述待解冻食材所需的理论解冻时长；将所述初始解冻时长与所述实际消耗时长之差确定为初始剩余解冻时长，以及将所述理论解冻时长与所述实际消耗时长之差确定为理论剩余解冻时长；如果所述理论剩余解冻时长和所述初始剩余解冻时长不满足近似相等，则按照所述理论剩余解冻时长，控制所述射频解冻装置对所述待解冻食材进行解冻。
在一些实施例中，失配频率可以解释为在一定时间内，调谐回路发生阻抗失配的次数(即进行阻抗匹配的次数)。待解冻食材在初始解冻时长的初期阶段，因为食材中大部分自由水以冰的形式存在，而冰的比热容较小，当吸收一定的能量时，食材升温比解冻后期要快，因此食材内部自由水的状态变化速度比解冻后期更快，使得初期调谐回路失配的频繁程度比解冻后期更高。因此，初始失配频率为整个待解冻食材解冻过程中的最大失配频率。
对于待解冻食材发生相变时的适配频率来说，由于不同食材的含水量和比热容均会影响失配频率的变化曲线的形状，因此不同食材发生相变时的失配频率(即参考失配频率)不是一个固定的值。
在一些实施例中，可以利用初始失配频率确定参考失配频率，示例性的，如果初始失配频率为F1，可以以F2＝F1×25％作为参考失配频率。通过实时监测失配频率，当监测到失配频率的值为所述参考失配频率时，则可以确定出实际消耗时长。
在一些实施例中，可以按照以下步骤确定理论解冻时长：计算所述初始失配频率与所述参考失配频率之间的比值，作为参考倍数；基于所述实际消耗时长，按照所述参考倍数确定所述射频解冻装置解冻所述食材所需的理论解冻时长。
在一些实施例中，假如确定到初始失配频率是60，参考失配频率是20，则可以计算到初始失配频率与参考失配频率的比值是3。如果食材解冻从初始失配频率变化至所述参考失配频率的实际消耗时长为0.5小时，则可以确定理 论解冻时长是1.5小时。
在一些实施例中，还可以按照如下的方式确定理论解冻时长。通过在实际消耗时长的基础上乘以一个经验值确定食材所需的理论解冻时长。示例性的，如果确定到实际消耗时长是0.5小时，经验值是5，则可以确定到理论解冻时长是2.5个小时。
在得到理论解冻时长后，基于初始解冻时长和实际消耗时长，确定初始剩余解冻时长以及理论剩余解冻时长，并判断初始剩余解冻时长与理论解冻时长是否近似相等。
在一些实施例中，可以是通过一个预设差值来判断是否满足近似相等，示例性的，设定预设差值为3min，如果理论剩余解冻时长为60min，初始剩余解冻时长为65min，则可以确定理论剩余解冻时长与初始剩余解冻时长不满足近似相等。
在另一些实施例中，可以是通过四舍五入的方式判断是否满足近似相等，示例性的，如果理论剩余解冻时长为64min，初始剩余解冻时长为60min，则通过四舍五入可以将理论剩余解冻时长认为是60min，则可以确定理论剩余解冻时长与初始剩余解冻时长满足近似相等。
可见，通过利用食材解冻过程中调谐回路的失配频率来重新确定食材的解冻时长，相当于对初始解冻时长有一定的修正。在一定程度上更能提高射频解冻装置对食材进行解冻的精准性。
第二种实现方式：
在所述射频解冻装置解冻食材的过程中，检测所述调谐回路的反射系数，所述反射系数用于表征所述射频功率放大回路的功耗程度；如果所述反射系数发生突变，获取所述射频解冻装置从解冻开始到所述反射系数发生突变的实际消耗时长，所述调谐回路在所述初始解冻时长初期的初始失配频率，以及所述调谐回路在所述反射系数发生突变时的参考失配频率；基于所述初始失配频率和所述参考失配频率，以及所述实际消耗时长，确定所述射频解冻装置解冻所述待解冻食材所需的理论解冻时长；将所述初始解冻时长与所述实际消耗时长之差确定为初始剩余解冻时长，以及将所述理论解冻时长与所述实际消耗时长之差确定为理论剩余解冻时长；如果所述理论剩余解冻时长和所述初始剩余解冻时长不满足近似相等，则按照所述理论剩余解冻时长，控制所述射频解冻装置对所述待解冻食材进行解冻。
食材在解冻的过程中，反射系数本应该是以平稳的趋势变化，但如果食材本身融合了较多的冰块，会使得在某一个时间点许多冰块一起融化为水，并在食材腔体中流动到一个新的位置，这样会破坏反射系数原本平稳的趋势变化状态。
在一些实施例中，调谐回路的反射系数的检测方式可以通过以下步骤实现：获取由所述射频功率放大回路输出的功率值，作为正向功率值，以及获 取由所述调谐回路输出的功率值，作为反向功率值；计算所述反射功率值与所述正向功率值之间的比值，并将所述比值确定为所述反射系数。
如果所述反射系数发生突变，获取所述射频解冻装置从解冻开始到所述反射系数发生突变的实际消耗时长，所述调谐回路在所述初始解冻时长初期的初始失配频率，以及所述调谐回路在所述反射系数发生突变时的参考失配频率；所述失配频率用于表征所述调谐回路被触发进行阻抗匹配的频繁程度。
需要说明的是，并不是所有食材在解冻的过程中一定会发生反射系数突变的情况。如果没有检测到反射系数发生突变，则可以控制所述射频解冻装置在所述初始解冻时长内对所述食材进行解冻。
对于理论解冻时长的确定方式，可以参考第一种实现方式中提供的方式，这里就不再赘述了。基于理论解冻时长、初始解冻时长和实际消耗时长，确定初始剩余解冻时长以及理论剩余解冻时长，并判断初始剩余解冻时长与理论解冻时长是否近似相等，以确定是否按照理论剩余解冻时长来对待解冻食材进行解冻。
可见，通过利用食材解冻过程中反射系数的突变情形重新确定食材的解冻时长，相当于对初始解冻时长有一定的修正。在一定程度上更能提高射频解冻装置对食材进行解冻的精准性。
为了防止出现过度解冻的发生，在一些实施例中，还可以执行以下步骤：
在以所述初始解冻时长的运行过程中，对所述待解冻食材的温度进行监测；若所述待解冻食材的温度达到所述目标温度，则停止对所述待解冻食材的解冻；若所述待解冻食材的温度在所述运行过程中均未达到所述目标温度，则运行所述初始解冻时长后停止对所述待解冻食材的解冻。
在一些实施例中，如果在解冻的过程中检测到待解冻食材的温度达到目标温度，表明待解冻食材已经基本上完成了解冻，为了避免出现食材的过解冻，此时若还没有达到初始解冻时长，则可以提前结束解冻。如果在整个解冻过程中待解冻食材的温度均小于目标温度，那么在运行初始解冻时长后，则停止对待解冻食材的解冻。
综上所述，本说明书实施例提供的方法，可以通过制冷设备中的已有传感器来获取待解冻食材的食材信息，不会增加设备的成本和复杂度。另一方面，通过传感器能够获取准确的待解冻食材的类型、质量等目标食材信息，基于目标食材信息确定出的射频解冻参数能够与待解冻食材相匹配，因此，通过该种方式确定出的来射频解冻参数对待解冻食材进行解冻能够有效提高解冻效果。
