[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] The top side of the shell 100 includes a control terminal 150, which is used to control the overall operation of the device; the freezer door 110 includes a human-machine interaction interface 111, which is used to open or close the freezer door 110. The human-machine interaction interface 111 can be set to display a QR code or scan and read data to facilitate the mother or caregiver to quickly submit information and save time for storing breast milk. The freezer door 110 should be provided with a plastic sealing strip to ensure the refrigeration sealing effect of the refrigerator and prevent breast milk from spoiling during storage.

[0039] The internal cavity 200 is provided with a storage sampling unit 210, a driving and disinfecting unit and a detection unit. The storage sampling unit 210 is used to store and sample breast milk, the driving and disinfecting unit is used to drive the storage sampling unit 210, and the detection unit is used to mark the breast milk and transmit the marked data to the control terminal 150.

A protruding cavity is arranged in the center of the storage device 213. The sampling rod 216 passes through the cylindrical storage device 213 through the protruding cavity, and samples and obtains breast milk in the storage device 213 through the protruding cavity. The storage device 213 and the sampling rod 216 are both detachably connected to the rotating disk 212, which can be achieved by, for example, a threaded connection, so as to facilitate the replacement of the storage device 213 and the sampling rod 216. In actual use, the storage device 213 and the sampling rod 216 are both single-use. They need to be cleaned and replaced in time after use to avoid breast milk remaining in the storage device 213 and the sampling rod 216, causing contamination of the device.

The driving motor 221 and the refrigeration compressor are arranged on one side of the bottom of the internal cavity 200. The driving shaft of the driving motor 221 is connected to the rotating disk 212. The driving motor 221 is used to drive the rotating disk 212 to rotate. A low-speed driving motor 221 should be selected or a differential should be used to reduce the transmission speed ratio to avoid the rotating disk 212 from rotating too fast. The refrigeration compressor is used for refrigeration. The refrigeration compressor is a conventional refrigeration compressor, which will not be described here. Those skilled in the art should further determine the specifications of the refrigeration compressor according to the cooling temperature required for breast milk and the specific size of the internal cavity 200 of the refrigerator. The disinfection lamp 222 is arranged on one side of the top of the internal cavity 200. The disinfection lamp 222 is used to disinfect the internal cavity 200.

[0043] The control terminal 150 is provided with a processor, and the processor is provided with a data encryption system, and the data encryption system includes a storage module, an encryption module and a transmission module.

[0044] The storage module includes a storage strategy, which includes: obtaining a start signal, obtaining maternal information through the human-computer interaction interface 111, and outputting an opening signal. After the control terminal 150 obtains the opening signal, it drives the freezer door 110 to open, and controls the rotation of the rotating disk 212 to control the empty storage 213 to be located at the freezer door 110, and outputs a detection signal. After the industrial camera 232 obtains the detection signal, it marks the position of this storage 213 and outputs the corresponding position information to the control terminal 150;

[0045] The storage strategy also includes: obtaining the cabinet ID where the device is located, the placement timestamp, and arranging and combining the above data:

[0046] Info=(GroupId,Direction,Time,Location)

[0047] Info is the name of the group data, GroupId is the cabinet ID where the device is located, Direction is the maternity information, Time is the placement timestamp, Location is the location information, and the encrypted signal is output

[0048] The encryption module includes an encryption strategy, which includes obtaining an encryption signal, obtaining an Info data group, the data storage format of the Info data group is a string, and combining the first characters of each group of data in the Info data group.

[0049] That is, the first characters of the four groups of data GroupId, Direction, Time, and Location are combined and processed by the digest algorithm to generate an irreversible message digest. The following is a sample python code for MD5 encryption. Different digest algorithms can be replaced according to needs for data encryption.

[0050]

[0051] The output result is irreversible message digest information, which is used for subsequent information verification.

[0052] The encryption strategy also includes obtaining an encryption signal, obtaining an Info data group, converting all characters in the Info data group into ASCII code values ​​through an ASCII code table, generating a corresponding ASCII code value array, adding a random number to the ASCII code value corresponding to each character, the random number value is 0-9, generating a new ASCII code value array, and obtaining the new ASCII code value array and an array composed of all random numbers. The following is a Python sample code:

[0053]

[0054]

[0055] Among them, ascii_values ​​is the ASCII code value array of the characters in the Info data group after conversion through the ASCII code table, random_numbers is a random number array composed of all random numbers, and new_ascii_values ​​is the new ASCII code value array generated by adding random numbers to the ASCII code value array.

[0056] The encryption strategy also includes: obtaining the public key of the receiver. The receiver is determined based on actual conditions and may be a cloud server or a rear-mounted optical fiber leakage monitoring device. The public key of the receiver is the public key provided by the key pair generated by the receiver. The random_numbers random number array is encrypting with the public key of the receiver to generate the encrypted random number information encrypt_random_numbers_message; the message digest result, the new ASCII code value array new_ascii_values ​​and the encrypted random number information encrypt_random_numbers_message are packaged to generate a data packet message.

[0057] The encryption strategy also includes generating an RSA key pair, signing the data packet with the RSA private key, generating the encrypted data packet ciphertext, and outputting the transmission signal. The following is a sample Python code for generating an RSA key pair and signing with a private key.

[0058]

[0059]

[0060] In the above code, the data packet message is in string format and is directly imported. If the format changes after packaging, you can use Python's built-in decompression module, such as zipfile, to decompress the data packet and then use the open function to open the data packet to obtain the required data. The above code is only an example and can be adjusted according to actual needs.

[0061] The RSA public key and private key are obtained through the above, and the private key is used to sign the data packet message to obtain the signature byte sequence signature.

[0062] The transmission module includes a transmission strategy, which includes obtaining a transmission signal, obtaining a data packet message and a signature byte sequence signature, transmitting the data packet message and the signature byte sequence signature to a cloud server or a rear optical fiber leakage monitoring device through a wireless data transceiver, completing the transmission of the bent optical fiber information data and outputting an end signal.

[0063] Working principle: The device obtains maternal information through the human-computer interaction interface 111, controls the freezer door 110 to open through the control terminal 150, and controls the drive motor 221 to drive the rotating disk 212 to rotate the empty storage 213 to the position closest to the freezer door 110, and obtains the position information of the storage 213 through the industrial camera 232. The data encryption system of the control terminal 150 obtains breast milk information data, screens and arranges the breast milk information data, and encrypts the breast milk information data, and finally outputs the encrypted breast milk information data to the upper control end, so as to realize the marking of breast milk from the time of storage, and facilitate the subsequent traceability query of breast milk; the device can be set to timed cleaning and disinfection or manually control disinfection, and then control the start / stop of the disinfection lamp 222.
