[0002] In the current packaging industry, there are extremely high requirements for product information identification and traceability. Although traditional identification methods, such as printing barcodes or QR codes directly on the packaging surface, meet the needs of information identification to a certain extent, they have problems such as easy destruction, easy imitation, and insufficient information concealment. Especially in some special fields, such as cosmetics, food, and medicine, there are more stringent requirements for the anti-counterfeiting, anti-tampering, and concealment of packaging information.

[0003] In order to solve the above problems, the industry has begun to explore new identification technologies. Among them, infrared transmission reading technology has gradually attracted attention due to its unique advantages. This technology uses a specially formulated infrared band ink to code under the opaque layer of the packaging material, and then reads it through a dedicated infrared observation device. Since the infrared wavelength is long and has strong penetration ability, it can read the coding information through thinner paper, film or silk-screen layers.

[0004] However, the existing infrared transmission reading technology still has some shortcomings in the application process. For example, the coding module may be affected by external environmental factors during the coding process, resulting in unstable coding quality; the infrared observation equipment may have low reading accuracy during the reading process due to factors such as light source intensity and detector sensitivity; in addition, there is also a lack of a complete system solution for how to verify and subsequently process the read coding information.

[0045] A coding module, the module being configured to code solid numbers or barcodes under an opaque paper, film or silk-screen layer using a specially formulated infrared band ink, wherein the infrared band ink has significantly enhanced absorption or fluorescence excitation characteristics within the infrared band;

[0046] Infrared observation equipment, which has an adjustable infrared light source and a highly sensitive infrared detector, is used to selectively stimulate or detect infrared signals in coding according to the characteristics of the infrared band ink, and read the coding information by transmitting thinner paper, film or silk-screen layer;

[0047] The coding verification module is connected to the infrared observation device to verify the accuracy and completeness of the coded information read to ensure the authenticity of the information;

[0048] Environmental adaptability layer, which is set between the coding module and the packaging material to resist the influence of external environmental factors such as humidity and temperature changes on the coding quality, and at the same time enhance the bonding strength between the coding layer and the packaging material;

[0049] An intelligent control unit is connected to the coding module and is used to modulate and control the emission of the infrared signal, receive and process external data to generate corresponding coding information, and send instructions to the coding module according to the processing results to realize automatic and intelligent control of coding.

[0050] The data processing module of the intelligent control unit further includes an adaptive weight coding algorithm, which adaptively adjusts the weight distribution in the coded information according to the characteristics and requirements of the external data. The weight adjustment is based on factors including the importance, urgency and redundancy of the data. The coded information with a specific structure and characteristics is generated through weighted processing. The coded information generation formula is C=f(D ˉ ), where D ˉ is the weighted data set.

[0051] Specifically, the coding module: Ink selection: Select ink with strong absorption or strong excitation fluorescence in the infrared band to ensure that the coding information can be effectively read under infrared light.

[0052] Coding equipment: Use high-precision printing equipment to print coding information such as solid numbers or barcodes under opaque paper, film or silk-screen layers.

[0053] Pretreatment unit: Pretreatment of the packaging material surface before coding, including cleaning the surface, applying primer or treatment agent, and adjusting the surface roughness to improve the adhesion between the ink and the packaging material and the coding quality.

[0054] The weight set W can be preset or dynamically adjusted according to specific needs. The weight adjustment strategy includes dynamically adjusting the weight according to the weight distribution law obtained by historical data analysis and the real-time data transmission demand; the communication module of the intelligent control unit further includes a compressed sensing data transmission algorithm, which uses the compressed sensing theory to compress and reconstruct the transmitted data, reduce the bandwidth and energy consumption of data transmission, and measure the vector y The generation formula is y=Φx, where x is the original data vector and Φ is the measurement matrix.

In the compressed sensing data transmission algorithm, the design and optimization of the measurement matrix Φ are based on the characteristics of data sparsity and correlation, and the selection and improvement of the reconstruction algorithm are carried out according to different application scenarios and requirements.

[0055] Specifically, the detection system: infrared observation equipment: is equipped with an infrared detector for capturing infrared signals emitted by coded information.

[0056] Intelligent recognition algorithm: built into the infrared observation equipment, used to automatically analyze, extract features, decode and verify the captured infrared signals to ensure the accuracy and reliability of the reading results.

[0057] The coding module uses precise inkjet printing technology to accurately code solid numbers or barcodes under opaque paper, film or silk-screen layers. The packaging material is pretreated before coding. The pretreatment step includes applying a layer of primer to enhance the bonding strength, so as to improve the bonding strength between the coding layer and the packaging material and the ability to resist environmental factors.

[0058] The coding module is also equipped with a pretreatment unit for pretreating the surface of paper, film or silk-screen layer before coding to improve the adhesion of ink to packaging materials and the coding quality. The pretreatment steps include: cleaning the surface to remove impurities and oil stains, applying a primer or treatment agent to enhance adhesion, and adjusting the surface roughness to optimize ink penetration and adhesion.

[0059] Specifically, applying a primer to enhance bonding: applying a layer of primer to enhance bonding on the cleaned surface. The primer has excellent adhesion and permeability, and can significantly improve the bonding between the ink and the packaging material.

[0060] The selection of primer needs to be matched according to the type and characteristics of the packaging material to ensure the best adhesion effect. The coating process must be uniform and without omissions to avoid bubbles or uneven thickness.

[0061] The specially formulated infrared band ink also includes an anti-ultraviolet additive to further enhance the long-term stability and anti-fading ability of the ink;

[0062] The infrared observation device also has an automatic calibration function, which can calibrate the light source and detector before each use to ensure the stability of reading accuracy;

[0063] The infrared observation device is also configured with an intelligent recognition algorithm, which is used to automatically analyze and identify the coding information of solid numbers or barcodes after the infrared detector captures the infrared signal. The intelligent recognition algorithm includes: an image preprocessing step for removing noise and enhancing image contrast; a feature extraction step for extracting coding features from the image; and a decoding step for restoring the original data based on the coding features. In addition, the intelligent recognition algorithm can also verify the integrity and accuracy of the coding information to ensure the reliability of the reading results; the coding verification module uses an advanced encryption algorithm to verify the read coding information to prevent the information from being tampered with or forged during transmission. The intelligent control unit includes a data processing module and a communication module. The data processing module is used to process and analyze the received external data to generate corresponding coding information; the communication module is used to communicate data with the coding module, the infrared observation device and external equipment to realize real-time transmission of information and issuance of control instructions.

[0064] Specifically, 1. Image preprocessing step: The main purpose of image preprocessing is to remove noise and enhance image contrast. This can be achieved through various filters and transformation methods. For example, a Gaussian filter can be used to smooth the image and remove noise, or histogram equalization can be used to enhance the contrast of the image.

[0065] Gaussian filter:

[0066]

[0067] Where G(x,y) is the kernel function of the Gaussian filter, (x,y) is the pixel coordinate, σ is the standard deviation, Histogram equalization: This step usually does not involve explicit mathematical formulas, but enhances contrast by calculating the image histogram and redistributing pixel values.

[0068] 2. Feature extraction steps

[0069] Feature extraction is to extract features from an image that are useful for identifying encoded information. This can be achieved through various methods, such as edge detection, corner detection, or texture analysis. Edge detection (taking Canny edge detection as an example): involves multiple steps, including Gaussian filtering, calculating gradients, non-maximum suppression, and double threshold detection. Since these steps involve complex algorithmic logic and mathematical operations, it is difficult to express them in a simple formula.

[0070] 3. Decoding step: The decoding step is to restore the original data based on the extracted coding features. This usually involves some form of decoding algorithm, such as barcode decoding algorithm or QR code decoding algorithm.

[0071] Barcode decoding algorithm: The specific algorithm of this step depends on the type of barcode and the encoding method. For example, for a one-dimensional barcode, a decoding algorithm based on the width of the bar and space can be used; for a two-dimensional barcode, a more complex decoding algorithm may be required to parse the encoded information.

[0072] 4. Verification step: The verification step is to check the integrity and accuracy of the encoded information. This can be achieved through various verification methods, such as checksum, checksum or cyclic redundancy check (CRC).

[0073] Cyclic Redundancy Check (CRC): CRC is a commonly used checksum method that detects errors in data by calculating the polynomial remainder of the data.

[0074] The calculation of a CRC usually involves complex mathematical operations and polynomial division.

[0082] S21, comprising the following steps: also comprising pre-treating the packaging material before coding to improve the bonding strength between the coding layer and the packaging material and the ability to resist environmental factors;

[0083] S22. After reading the coding information, the information is transmitted to the cloud database through the communication module of the intelligent control unit for storage and analysis to achieve remote monitoring and information traceability.

[0084] Specifically, in the preparation stage: place the product to be read under the infrared observation equipment, and ensure that the coding information is facing the infrared detector. Adjust the parameters of the infrared observation equipment, such as light source intensity, detector sensitivity, etc., to adapt to different coding materials and reading environments.

[0085] Reading stage: Start the infrared observation device, and the infrared detector begins to capture the infrared signal emitted by the coded information. The intelligent recognition algorithm pre-processes the captured infrared signal to remove noise and enhance image contrast. The coding features in the image are extracted, and decoded according to the coding features to restore the original data. The decoded data is verified to ensure the integrity and accuracy of the data.

[0086] Subsequent processing stage: The read coding information is stored in the database for subsequent traceability and query. The read information is further processed and analyzed as needed, such as anti-counterfeiting verification, quality traceability, etc.
