Description

Technical Field

[0001] The present invention belongs to the technical field of solid beverage packaging information tracing, and in particular relates to a solid beverage packaging query tracing method and system. Background Art

[0002] At present, the traceability of solid beverage products mainly focuses on the basic information records during storage and transportation, while the monitoring and quality traceability of the packaging process are relatively weak. Especially for solid beverage products, environmental conditions such as temperature, humidity, and vibration during the packaging process may directly affect product quality. For example, too high or too low temperature may change the physical properties of solid beverages, too high humidity may cause the product to be damp or the performance of the packaging material to deteriorate, and vibration during the packaging process may cause powder agglomeration or packaging damage, and also cause uneven usage. These problems are usually difficult to discover in real time through traditional traceability methods, thereby increasing the risk of substandard product quality before leaving the factory. In the prior art, although some of them can record the packaging environment, it is difficult to achieve real-time monitoring and abnormal reminders. Quality inspectors cannot promptly discover abnormal problems in the packaging process and take effective measures, which may not only cause some defective products to enter the subsequent links, but also increase the company's costs and the risk of product recalls. Therefore, there is an urgent need for a traceability method that can record and monitor environmental data of the packaging process in real time, so that quality inspectors can discover potential problems in real time in the background, adjust the packaging in time or remove abnormal products, thereby improving the stability of product quality and production efficiency.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0058] Figure 2 The present invention is a schematic diagram of equipment for a solid beverage packaging query and tracing method. DETAILED DESCRIPTION

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Embodiment 1: Figure 1, which is a flow chart of a first embodiment of a method for querying and tracing solid beverage packaging of the present invention, provides a first embodiment of a method for querying and tracing solid beverage packaging of the present invention.

[0061] In a first embodiment, the solid beverage packaging query and tracing method includes:

[0062] Step S10: a detachable traceability chip is arranged on the outside of the solid beverage package, wherein the traceability chip includes a traceability chip main area and a plurality of traceability chip sub-areas, and the core traceability information is stored in the traceability chip main area, wherein the core traceability information includes the production date D, the batch number B, and the production line number L; the auxiliary traceability information is stored in the traceability chip sub-area, wherein the auxiliary traceability information includes the temperature information T, the humidity information M, and the vibration information V;

[0063] It should be noted that the traceability chip uses a micro NFC snap-on chip based on RFID technology. It is installed on a corner of the packaging material during the packaging process, removed and stored after the entire packaging process is completed, and the data recorded by the chip is uploaded to the traditional MySQL database for initialization, and then fed back to the starting end of the packaging process for recycling. The temperature information T, humidity information M and vibration information V are collected by sensors at the solid position on the packaging production line, and the sensors are equipped with NFC reading and writing functions.

[0064] It should be noted that the installation and information storage of the traceability chip main area and traceability chip sub-area are completed during the packaging process. The traceability chip main area is given core traceability information such as production date, batch number, production line number, etc. during packaging to ensure the unique identification of each product.

[0065] It should be understood that by recording temperature data, the background can monitor the temperature changes of solid beverages during the packaging process. For example, if the storage temperature of a batch of beverages exceeds the set safety range, such as too high temperature causing dissolution or too low temperature causing changes in physical properties, it can be marked as "abnormal traceability status" when querying traceability, thereby reminding quality inspectors that the product may have quality problems; humidity monitoring can help identify situations where the packaging is damp or too dry. For example, too high humidity may cause damage to the packaging material or moisture absorption of the internal beverage, while too low humidity may affect the powder fluidity of the beverage, providing a reference for quality control; and vibration data can reflect the bumps and impacts during the packaging process. For example, excessive vibration may cause damage to the packaging or agglomeration of the beverage powder, and will also increase the error between the actual net content of the solid beverage and the standard net content. The background can promptly feedback abnormal conditions in the packaging process to the quality inspectors through the vibration information recorded in the secondary area of ​​the traceability chip.

[0066] Step S20: construct a Merkle tree based on the core traceability information and the auxiliary traceability information, generate a root hash value R, and store the root hash value R in the main area of ​​the traceability chip;

[0067] The specific process of constructing a Merkle tree includes:

[0068] Generate a separate hash value for each core traceability information in the main area of ​​the traceability chip, including the hash value H(D) of the production date, the hash value H(B) of the batch number, and the hash value H(L) of the production line number;

[0069] Generate segmented hash values ​​for the auxiliary traceability information in the secondary area of ​​the traceability chip: the hash value H(T) of the temperature data, the hash value H(M) of the humidity data, and the hash value H(V) of the vibration data, and combine the segmented hash values ​​into a complete hash value H(S), where H(S) = H(H(T)+H(M)+H(V));

[0070] The hash value H(D) of the production date, the hash value H(B) of the batch number, the hash value H(L) of the production line number, and the H(S) in each traceability chip sub-area are used as leaf nodes of the Merkle tree;

[0071] Calculate the root hash value R of the root node. The calculation formula is:

[0072]

[0073] Where n is the number of traceability chip sub-regions, j is the jth traceability chip sub-region, H(S j ) is the complete hash value of the jth traceability chip sub-area;

[0074] It should be noted that the Merkle tree construction process in this step is intended to perform multi-level integrity verification on the core traceability information and auxiliary traceability information. By generating hash values ​​for the information stored in the main area of ​​the traceability chip and the secondary area of ​​the traceability chip, and using these hash values ​​as leaf nodes of the Merkle tree, it can be ensured that each traceability information can be verified individually. In addition, the generated root hash value R is stored in the main area of ​​the traceability chip so that global data consistency verification can be performed during query to ensure that all traceability information has not been tampered with.

[0075] It is understandable that by combining the core traceability information and the auxiliary traceability information into a complete hash structure, not only the security of the traceability data is enhanced, but also the background can quickly verify the integrity of any data. The hierarchical structure of the Merkle tree ensures that even if a certain data changes, the root hash value will change accordingly, thus indicating that the data integrity is abnormal.

[0076] For example, if a batch of beverage products generates the following information during the packaging process:

[0077] The production date is "2023-11-15";

[0078] The batch number is "A12345";

[0079] The production line number is "Line1";

[0080] The storage environment monitoring information is temperature T = 20°C, humidity M = 50%, and vibration V = 0.5g;

[0081] When generating the Merkle tree, the hash values ​​H(D), H(B), H(L), H(T), H(M), and H(V) of each information item are calculated in turn, and combined to generate the complete hash value H(S) of each traceability chip sub-area. Finally, all these hash values ​​are combined to generate the root hash value R, which is stored in the traceability chip main area as the unique check code of the overall traceability information, so as to verify the integrity of the data in the subsequent query process.

[0082] Step S30: After receiving the query request, perform multi-layer verification on the traceability data:

[0083] First level verification: Verify the consistency of multi-level hash verification auxiliary traceability information;

[0084] The second level of verification: compare and verify the auxiliary traceability information with the set security threshold;

[0085] When the auxiliary traceability information is inconsistent or exceeds the safety range, "abnormal traceability status" is marked in the auxiliary traceability information;

[0086] It should be noted that the multi-layer verification process of step S30 is divided into two parts: the first layer verification and the second layer verification. The first layer verification verifies the data consistency of the auxiliary traceability information through multi-level hashing to ensure that all data has not been tampered with during the traceability process. The second layer verification compares and verifies the auxiliary traceability information with the set security threshold to determine whether the product is in a safe environment during the packaging process.

[0087] It is understandable that the safety threshold of auxiliary traceability information is mainly used to monitor key environmental parameters of products during packaging, such as temperature, humidity and vibration. If any data is monitored to exceed the set threshold, such as too high temperature or too low humidity, the product will be marked as "abnormal traceability status" to remind quality inspectors that the product may have storage safety risks.

[0088] For example, suppose that during the query process, the temperature data stored in the secondary area of ​​the traceability chip is detected to be 30°C, while the set safety temperature threshold is 25°C. When the temperature exceeds the safety range, the second layer of verification will fail, and the "abnormal traceability status" will be marked in the query result, and a prompt message of abnormal temperature will be displayed. In this way, quality inspectors can promptly learn that the batch of products may have experienced a high temperature environment during the packaging process, thus affecting product quality.

[0089] Step S40: When the mark "abnormal tracing state" is detected during the query process, the adaptive data repair method is started, and the timestamp of the main area of ​​the tracing chip is set to T core , the timestamp set of the traceability chip sub-area is T aux ={t1,t2,...t n}, according to the timestamp of the main area of ​​the traceability chip and the timestamp of the secondary area of ​​the traceability chip, the core traceability information and auxiliary traceability information corresponding to the maximum timestamp are automatically selected for repair, and the repaired traceability data and the auxiliary traceability information are used together to generate a complete query report;

[0090] Among them, t1, t2, ... t n The timestamp information attached to each auxiliary traceability information data segment; the complete query report contains the auxiliary traceability information marked with "abnormal traceability status".

[0091] It should be noted that when a state marked as "abnormal traceability status" is detected during the query process, the adaptive data repair method will automatically start to ensure the integrity and reliability of the traceability data. This method selects the data with the latest timestamp for repair, thereby ensuring that the traceability information closest to the current state is provided without affecting the accuracy of the data.

[0092] It is understandable that during the data repair process, the corresponding core traceability information and auxiliary traceability information will be selected according to the maximum timestamp to fill in the abnormal data. This adaptive data repair mechanism can effectively solve the data inconsistency problem caused by environmental changes or data corruption, and generate a complete query report. The "abnormal traceability status" will be marked in the report, and the possible abnormal reasons will be displayed so that the quality inspectors can know. For example, suppose that the temperature data of a batch of products in the secondary area of ​​the traceability chip is detected to be out of the safe range, which is marked as "abnormal traceability status". When the repair is started, the timestamp of the main area of ​​the traceability chip and the timestamp set of the secondary chip will be checked first. The core traceability information and auxiliary traceability information corresponding to the maximum timestamp will be used to generate a complete traceability report after the repair, and the relevant abnormal information will be marked. In this way, quality inspectors can obtain the latest and most complete traceability information and know the potential risks of the product in the packaging process.
