Breast milk is the primary food source for newborns and young children. After long-term cold storage, breast milk is deteriorated. If the infant is fed with the deteriorated breast milk by mistake, the infant can be diarrhea, even fever and other serious adverse reactions can occur. Therefore, how to identify the freshness of the refrigerated breast milk becomes a technical problem to be solved.
In view of the above problems, the related art discloses a breast milk storage refrigerator comprising a case, a refrigerating device disposed outside the case, and a controller. The controller is configured with a timer for timing the feeding bottle. The controller is used for obtaining the storage time of the milk bottle through the timer, and reminding through a display screen electrically connected with the controller when the storage time reaches the set overdue storage time so as to distinguish fresh breast milk from overdue breast milk.
The related art indirectly determines the freshness of the breast milk through the storage time of the breast milk, however, the storage time cannot accurately reflect the freshness of the breast milk. Therefore, the breast milk freshness judging method adopted by the related technology has poor accuracy.
Embodiments of the present disclosure provide a refrigeration appliance configured with a refrigeration compartment, a processor, and an RFID (Radio Frequency Identification ) reader. The refrigerating chamber stores a storage device for storing breast milk. The storage device is attached with an electronic tag. The electronic tag includes a radio frequency identification RFID tag and an RFID antenna. The RFID tag is communicatively coupled to the RFID antenna. The RFID reader is in communication with the RFID tag through an RFID antenna. The processor is electrically connected with the RFID reader. The refrigerating equipment comprises refrigerating equipment with refrigerating function such as a refrigerator, a freezer and the like.
Based on the above-mentioned refrigeration apparatus, referring to fig. 1, an embodiment of the present disclosure provides a method for detecting freshness of breast milk, including:
s01, the processor acquires an electric signal related to dielectric properties of breast milk through the electronic tag.
S02, the processor determines the freshness of the breast milk according to the electric signals.
With the method for detecting the freshness of the breast milk provided by the embodiment of the disclosure, deterioration of the breast milk is caused by metabolism of components in the breast milk by microorganisms in the breast milk, and conductive particles in the breast milk are changed in the process of metabolism of the microorganisms. That is, the dielectric properties of breast milk may reflect the freshness of breast milk. According to the embodiment of the disclosure, the electronic tag is used for acquiring the electric signal related to the dielectric property of the breast milk, and the dielectric property can be converted into the electric signal, so that the freshness of the breast milk is determined in the form of the electric signal, and the accuracy of judging the freshness of the breast milk is improved. In addition, the embodiment of the disclosure judges the freshness of the breast milk by attaching the electronic tag on the storage device, so that nondestructive detection of the freshness of the breast milk is realized.
Fig. 5 is a graph showing a change in the time dimension of the amount of change in the resonance frequency corresponding to the radio frequency signal associated with the dielectric characteristics of each of breast milk and water. In the case of the storage device storing water, as shown in fig. 5, since the dielectric property of water is unchanged in the time dimension, the variation of the resonant frequency corresponding to the rf signal keeps a value of zero. When breast milk is stored in the storage device, the dielectric property of the breast milk is changed in the time dimension, the variation of the resonant frequency corresponding to the radio frequency signal is in an increasing trend in the time period of 0-35 h, and the increasing trend is gradually slowed down in the time period of 35-45 h. As can be seen from fig. 5, the amount of change in resonance frequency gradually increases with the change in dielectric characteristics of breast milk. The increasing trend is approximately that the increasing trend is rapid, the increasing trend is gradually increased after the increasing trend reaches a certain peak value, and finally, the increasing trend is basically maintained.
Referring to fig. 2, the processor obtains an electrical signal associated with a dielectric property of breast milk through the electronic tag, including:
s11, the processor reads radio frequency signals associated with the dielectric characteristics by utilizing the RFID tag.
S12, the processor analyzes the radio frequency signals through the RFID reader, and determines the resonant frequency corresponding to the radio frequency signals so as to determine the freshness of the breast milk according to the resonant frequency.

Finally, judging the freshness of the breast milk through the resonance frequency. Therefore, the accuracy of judging the freshness of the breast milk is improved.
Optionally, the processor reads the radio frequency signal associated with the dielectric property by the RFID tag, comprising:
the processor reads the radio frequency signal associated with the dielectric property at intervals.
The processor reads the radio frequency signals associated with the dielectric characteristics at intervals, and may periodically acquire the radio frequency signals according to a preset period. The preset period value can be determined according to actual requirements. As an example, the preset period is a value of 20 minutes, 30 minutes, or 1 hour, etc. It can be appreciated that the smaller the preset cycle number, the higher the accuracy of the milk freshness discrimination.
The processor determines a resonant frequency corresponding to the radio frequency signal, comprising:
the processor analyzes the radio frequency signals read at intervals and determines the resonant frequency corresponding to each radio frequency signal.
In this way, since the dielectric properties of breast milk change with time, the embodiment of the disclosure analyzes the radio frequency signals read at intervals after reading the radio frequency signals associated with the dielectric properties of breast milk to determine the resonant frequencies corresponding to the radio frequency signals, so as to determine the freshness of breast milk according to the resonant frequencies. Therefore, the embodiment of the disclosure converts the dielectric characteristic into the radio frequency signal, analyzes the radio frequency signal, determines the resonant frequency, and then determines the freshness of the breast milk according to the resonant frequency, thereby effectively improving the accuracy of discriminating the freshness of the breast milk. At the same time, the embodiments of the present disclosure facilitate non-destructive testing of breast milk freshness.
Optionally, as shown in connection with fig. 3, the processor determines the freshness of the breast milk from the electrical signal, including:
s21, the processor calculates the variation of the resonant frequency at adjacent moments according to the resonant frequency corresponding to each radio frequency signal.
S22, the processor determines the freshness of the breast milk according to the variable quantity of the resonant frequencies.
In this way, the variation of the resonant frequency gradually increases along with the variation of the dielectric characteristic of the breast milk, so that the embodiment of the disclosure can judge the freshness of the breast milk according to the variation of a plurality of resonant frequencies, thereby improving the accuracy of judging the freshness of the breast milk and reducing the complexity of calculating the freshness of the breast milk.
Optionally, the processor determines the freshness of the breast milk according to the variation amounts of the plurality of resonance frequencies, including:
and determining that breast milk is spoiled in the case that the variation of the plurality of resonance frequencies is greater than or equal to a preset frequency value.
Wherein the variation of the resonance frequency represents the absolute value of the difference between the resonance frequency at the present time and the resonance frequency at the previous time.
Thus, it is found through experiments that the dielectric properties of breast milk are greatly changed when the breast milk is deteriorated. Accordingly, the variation of the radio frequency signal and the resonance frequency obtained through analysis is higher than or equal to the preset frequency value. Therefore, the embodiment of the disclosure compares the variation of the resonance frequency with the preset frequency value, and determines that breast milk is spoiled when the variation of the resonance frequency is greater than or equal to the preset frequency value.
