Description

Technical Field

[0001] This invention belongs to the technical field of product traceability management systems, specifically relating to a product full-process traceability management system and method. Background Technology

[0002] With consumers increasingly focused on food safety, the quality, safety, and traceability of tea, as an important agricultural product, have become core requirements for the industry's development. Currently, the entire process of tea production, processing, and sales is relatively independent. Some product traceability systems can only trace the processing or sales stages, failing to cover the tea-picking source and the tea farmers' collection process. During the tea-collection and trading process, the transactions are independent, making it difficult to retain and trace transaction information. The information of tea processing enterprises is relatively independent from the packaging information of the final tea sold, making it difficult to achieve traceability of the processing stage. Traceability labels are mostly ordinary QR codes, which are easily counterfeited, and consumers cannot trace pesticide residue testing information after scanning the code. It is difficult to obtain complete traceability data for the entire life cycle of tea, making it difficult to effectively protect consumers' right to know and product quality and safety.

[0003] To address the aforementioned issues, this paper proposes a full-process traceability management system and method that covers all stages of tea production, including tea picking, collection, trading, processing, testing, packaging, and consumption. This system enables seamless information sharing across all stages and includes functions such as transaction traceability, pesticide residue testing information query, and anti-counterfeiting measures, in order to meet the needs of industry development and consumers. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a product full-process traceability management system and method. This system enables full-chain traceability of tea from the tea-picking source, tea farmers' collection, card transactions, tea processing, pesticide residue testing, and end-consumer consumption. It ensures that information at each stage is traceable and verifiable, transaction information is deeply linked to traceability information, and the traceability label has anti-counterfeiting functions, thus protecting the quality and safety of tea and consumers' right to know. The specific technical solution is as follows: A product traceability management system and method includes a traceability management platform, a tea-picking source information collection module, a tea-collecting transaction information collection module, a tea-processing enterprise information collection module, a pesticide residue testing information collection module, a traceability code generation and assignment module, an anti-counterfeiting module, and a consumer query module. Each module is wirelessly connected to the traceability management platform to achieve data interaction and synchronization. The traceability management platform uses a distributed database to store traceability data and also includes a data access control unit. The platform connects to a POS terminal to link transaction information with traceability information. The tea-picking source information collection module is used to collect source information of the tea picking process, including tea farmer identity information, tea garden location information, tea picking time, tea variety, and picking batch. The information collection is completed by entering or scanning the tea farmer's identity card through a mobile terminal. After collection, it is uploaded to the traceability management platform in real time to realize the traceability of tea picking source information. The tea purchase transaction information collection module includes a traceability scale and a POS terminal. The traceability scale is used to weigh the tea sold by tea farmers, collect weighing data, and generate weighing traceability information. The POS terminal is wirelessly connected to the traceability scale. The POS terminal receives the weighing data from the traceability scale and completes the tea purchase transaction, recording the transaction information. After the transaction is completed, the POS terminal associates the weighing traceability information, transaction information, and tea source information, and uploads them together to the traceability management platform to achieve traceability of the tea purchase process and transaction information. The card swipe transaction information is encrypted and stored using blockchain technology to ensure that it is tamper-proof, verifiable, traceable, and fully queryable. The tea-frying enterprise information collection module collects relevant information about tea-frying enterprises, including enterprise qualification information (business license, production license), processing equipment information, tea-frying process parameters, processing batches, and processing personnel information. The information collection is completed by entering or scanning relevant qualification documents through the enterprise terminal. After collection, the information is uploaded to the traceability management platform to realize the traceability of information about tea-frying enterprises and processing links. The pesticide residue detection information collection module collects pesticide residue detection information of tea, including testing institution information, testing time, testing items, and testing results. The information collection is completed by entering or scanning the test report through the testing institution's terminal. After collection, the information is uploaded to the traceability management platform and associated with the traceability information of the corresponding batch of tea. The traceability code generation and coding module generates a unique traceability code based on the traceability data of the entire tea process in the traceability management platform. The traceability code is generated using a dynamic encryption algorithm and includes a QR code and an encrypted string. After the traceability code is generated, it is printed on the tea packaging using an inkjet printer. The traceability code corresponds one-to-one with the weighing traceability information generated by the traceability scale, ensuring that each package of tea has a unique traceability identifier. The anti-counterfeiting module is used to add anti-counterfeiting functions to the traceability code, and adopts a dual anti-counterfeiting mechanism of "physical anti-counterfeiting + digital anti-counterfeiting": physical anti-counterfeiting uses laser engraving and VOID anti-counterfeiting coating technology to prevent the traceability code from being copied or tampered with; digital anti-counterfeiting uses the traceability management platform to encrypt the traceability code, each traceability code corresponds to a unique encryption key, and the traceability code query records are synchronized to the traceability management platform in real time. When an abnormal query occurs, the system will automatically issue an alert. At the same time, consumers can scan the code to view the anti-counterfeiting verification result of the traceability code, thus realizing the anti-counterfeiting function of the traceability label. The consumer query module allows consumers to scan the traceability code on the packaging using their mobile devices, which will redirect them to the query interface of the traceability management platform. Consumers can then view the full-chain traceability information of the corresponding tea, including information on the tea-picking source, tea-collecting and trading information, tea-processing company information, pesticide residue testing information, and weighing information. They can also view the anti-counterfeiting verification results, achieving the effect of instant query and full traceability.

[0005] Furthermore, the distributed database, combined with blockchain technology, enables the immutability and traceability of traceability data, ensuring the authenticity and integrity of information at each stage. The data access control unit assigns different query and operation permissions to different users, such as tea farmers, tea purchasing companies, tea processing companies, testing institutions, and consumers, to ensure data security.

[0006] Furthermore, the tea-picking source information collection module can also collect environmental information of the tea garden through IoT devices and upload it in conjunction with the tea-picking source information, enriching the dimensions of traceability data.

[0007] Furthermore, the POS terminal in the tea transaction information collection module supports multiple card payment methods, such as bank cards, agricultural benefit cards, and mobile payment cards. After the transaction is completed, a transaction voucher is automatically generated. The transaction voucher is printed with a corresponding traceability code, which is convenient for both parties to retain and verify. At the same time, the transaction data is synchronized to the traceability management platform in real time, realizing two-way traceability of transaction information and traceability information.

[0008] Furthermore, the testing information collected by the pesticide residue testing information collection module can also be linked to the qualification certification information of the testing institution. When consumers scan the code to query, they can simultaneously view the relevant qualifications of the testing institution, which enhances the credibility of the pesticide residue testing results. At the same time, if the test results are unqualified, the traceability management platform will automatically lock the corresponding batch of tea, prohibit it from entering the market, and issue a warning message.

[0009] Furthermore, the traceability code generated by the traceability code generation and assignment module can also include information such as product batch, packaging time, and shelf life. The traceability code supports offline querying, and consumers can obtain basic traceability information by scanning the traceability code in an offline environment. After connecting to the network, they can view the complete traceability information.

[0010] This invention also provides a product end-to-end traceability management method, which, based on the above-mentioned traceability management system, includes the following steps: S1. Tea Picking Source Information Collection: Through the tea picking source information collection module, tea farmer identity information, tea garden location, tea picking time, tea variety, picking batch and other source information are collected and uploaded to the traceability management platform in real time to establish a tea picking source traceability file; S2. Tea Collection and Transaction Information: Tea farmers deliver the picked tea leaves to the collection point, where the tea leaves are weighed using a traceability scale. The scale collects the weighing data and generates weighing traceability information. The tea collectors complete the transaction via a POS terminal, which records the transaction information and links the weighing traceability information, transaction information, and tea source information from step S to the traceability management platform. This establishes a tea collection and transaction traceability file, with the transaction information encrypted using blockchain technology to ensure it cannot be tampered with. S3. Information Collection of Tea Processing Enterprises: Through the information collection module of tea processing enterprises, information such as the qualification information, processing equipment information, tea processing parameters, processing batches, and processing personnel of tea processing enterprises are collected and uploaded to the traceability management platform. This information is then linked with the tea purchase and transaction traceability information of the corresponding batch of tea to establish a traceability file for tea processing. S4. Collection of pesticide residue testing information: After the tea is processed, the testing agency will conduct pesticide residue testing on the tea. Through the pesticide residue testing information collection module, information such as testing agency information, testing time, testing items, and testing results will be collected and uploaded to the traceability management platform. This information will be linked with the tea processing traceability information of the corresponding batch of tea to establish a pesticide residue testing traceability file. S5. Traceability Code Generation and Assignment: The traceability code generation and assignment module generates a unique traceability code based on the traceability data stored in the traceability management platform, which covers the entire process from tea picking to tea trading, tea processing, and pesticide residue testing. The traceability code is then printed on the tea packaging using an assignment device, achieving a one-to-one correspondence between the traceability code and the tea packaging. Furthermore, the traceability code is bound to the weighing traceability information generated by the traceability scale. S6. Anti-counterfeiting measures: The traceability code on the packaging is subjected to double anti-counterfeiting measures through the anti-counterfeiting module. At the physical level, laser engraving and VOID anti-counterfeiting coating are used. At the digital level, the traceability code is encrypted through the traceability management platform, and the query history of the traceability code is recorded to realize abnormal query warning. S7. Consumer Inquiry and Traceability: Consumers can scan the traceability code on the packaging using their mobile devices to access the traceability management platform's query interface, view the full-chain traceability information of the corresponding tea, and check the anti-counterfeiting verification results to complete the traceability query. If abnormal information is found or the anti-counterfeiting verification fails, feedback can be submitted to the traceability management platform through the query interface.

[0011] Furthermore, in step S2, after the tea purchase transaction is completed, the POS terminal automatically prints a transaction voucher. The transaction voucher contains a traceability code, transaction information, and weighing information, which is convenient for tea farmers and tea purchasing companies to retain and verify. At the same time, the traceability management platform classifies and statistically analyzes the transaction information, supporting tea purchasing companies and regulatory departments to query transaction details.

[0012] Furthermore, in step S5, when generating the traceability code, the national cryptographic SM9 dynamic encryption algorithm is used to ensure the uniqueness and security of the traceability code. The traceability code is also bound to the batch information and packaging information of the tea to avoid confusion between traceability codes of different batches of tea.

[0013] Furthermore, in step S7, when a consumer scans the code to query, the traceability management platform automatically records the query time, the query device model, and the query IP address. If the same traceability code is queried by 3 or more different devices within 1 hour, the system automatically issues an anti-counterfeiting warning and prompts the consumer on the query interface that "the traceability code is abnormal, please verify the authenticity of the product." At the same time, the warning information is pushed to the supervision end of the traceability management platform for the convenience of supervisory personnel to verify.

[0014] This invention provides a product end-to-end traceability management system and method, which has the following beneficial effects: This invention enables full-chain traceability of tea, covering all stages from tea picking, tea collection and trading, tea processing, pesticide residue testing, packaging, and consumption. Information from each stage is seamlessly linked, ensuring that the source of tea can be traced and its destination can be tracked, thus solving the problem of incomplete stages in existing traceability systems.

[0015] In addition, by integrating traceability scales and POS terminals, the weighing data, transaction information and traceability information of tea collection transactions are deeply bound together. The transaction information is encrypted and stored using blockchain technology, which is tamper-proof and can be queried throughout the process, realizing the traceability of the tea collection transaction process and filling the gap in the existing system where transaction information cannot be effectively traced.

[0016] In addition, the traceability code is directly linked to pesticide residue testing information. Consumers can scan the code to view the pesticide residue test results of the tea and the qualifications of the testing institution, which enhances the credibility of product quality. At the same time, the traceability code adopts a dual anti-counterfeiting mechanism of "physical + digital", which effectively prevents the traceability code from being forged or tampered with, improves the anti-counterfeiting performance of the product, and protects consumer rights.

[0017] In addition, the traceability management platform has functions such as data storage, analysis, query, and access control. It supports collaborative use by multiple entities, including tea farmers, tea purchasing companies, tea processing companies, testing institutions, regulatory departments, and consumers. Data is synchronized in real time, improving the efficiency of traceability management.

[0018] In addition, the methodology is clear and easy to follow, with convenient information collection at each stage. It requires no complicated operations, making it easy to promote and apply in the tea industry. It can effectively regulate the tea market order, improve the quality of tea products, and enhance consumers' trust in tea products. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments to facilitate a clear understanding of the content of the present invention. However, the scope of protection of the present invention is not limited to the following embodiments.

[0024] like Figure 1-2As shown, this embodiment provides a product full-process traceability management system and method, including a traceability management platform 1, a tea-picking source information collection module 2, a tea-collecting transaction information collection module 3, a tea-processing enterprise information collection module 4, a pesticide residue testing information collection module 5, a traceability code generation and assignment module 6, an anti-counterfeiting module 7, and a consumer query module 8. Each module is wirelessly connected to the traceability management platform 1 to achieve data interaction and synchronization. The traceability management platform 1 uses a distributed database 9 to store traceability data. The traceability management platform 1 also has a data access control unit 10. The traceability management platform 1 is connected to a POS terminal 32 to achieve the association and binding of transaction information and traceability information. The tea-picking source information collection module 2 collects source information from the tea-picking process. The system includes information on tea farmers' identities, tea garden locations, picking times, tea varieties, and picking batches. This information is collected via mobile terminals (such as smartphones or dedicated data collection devices) by entering or scanning tea farmer identification (such as ID cards or unique traceability cards). The collected information is then uploaded in real-time to the traceability management platform 1, enabling traceability of the tea-picking source. The tea transaction information collection module 3 includes a traceability scale 31 and a POS terminal 32. The traceability scale 31 weighs the tea sold by tea farmers, collects weighing data (such as weight, unit price, and total price), and generates weighing traceability information. The POS terminal 32 is wirelessly connected to the traceability scale 31, receiving the weighing data and simultaneously completing the tea transaction. The POS terminal 32 records transaction information (such as transaction time, transaction amount, identity information of both parties, card account, and transaction serial number). After the transaction is completed, the POS terminal 32 associates the weighing traceability information, transaction information, and tea-picking source information, and uploads them together to the traceability management platform 1 to achieve traceability of the tea-collection process and transaction information. The card transaction information is encrypted and stored using blockchain technology. For example, it uses an architecture that combines off-chain storage details with on-chain evidence hashing. Off-chain encrypted storage: Transaction information such as card number, transaction amount, time, and merchant number are encrypted in the background of the POS terminal 32 using symmetric encryption that conforms to financial industry standards. The encryption key is centrally managed by the acquiring institution or bank in the hardware security module to ensure the installation level. The encrypted ciphertext is stored in the acquiring institution's database. In a private, highly secure centralized database of a single institution or bank, on-chain evidence storage is used: the hash value of key transaction elements and off-chain stored encrypted text is used to generate a transaction evidence fingerprint. This fingerprint is then written into a permissioned blockchain through a transaction, ensuring that it is tamper-proof, verifiable, traceable, and fully queryable. The tea-frying enterprise information collection module 4 is used to collect relevant information about tea-frying enterprises, including enterprise qualification information (business license and production license), processing equipment information, tea-frying process parameters (kill-green temperature, rolling time, drying time, etc.), processing batches, and processing personnel information. Information collection is completed by entering or scanning relevant qualification documents through the enterprise terminal. After collection, the information is uploaded to the traceability management platform 1 to achieve traceability of information about tea-frying enterprises and processing links.The pesticide residue testing information collection module 5 collects pesticide residue testing information for tea, including testing institution information, testing time, testing items (such as pesticide residue types and residue amounts), and testing results. Information collection is completed by entering or scanning the testing report through the testing institution's terminal. After collection, the information is uploaded to the traceability management platform 1 and linked to the traceability information of the corresponding batch of tea. The traceability code generation and coding module 6 generates a unique traceability code based on the full-process traceability data of tea in the traceability management platform 1 (such as tea picking source, tea collection and trading, tea processing, pesticide residue testing, etc.). The traceability code is generated using a dynamic encryption algorithm and includes a QR code and an encrypted string. After generation, the traceability code is printed on the tea packaging using an inkjet printer. The traceability code corresponds one-to-one with the weighing traceability information generated by the traceability scale 31, ensuring that each package of tea has a unique traceability identifier. The anti-counterfeiting module 7 adds anti-counterfeiting functionality to the traceability code, employing a dual anti-counterfeiting mechanism of "physical anti-counterfeiting + digital anti-counterfeiting": physical anti-counterfeiting uses laser... Light engraving and VOID anti-counterfeiting coating technologies prevent the traceability code from being copied or tampered with. Digital anti-counterfeiting uses the traceability management platform 1 to encrypt the traceability code. Each traceability code corresponds to a unique encryption key, and the query records of the traceability code (query time, query device, number of queries) are synchronized to the traceability management platform 1 in real time. When abnormal queries occur (such as the same traceability code being queried multiple times on different devices in a short period of time), the system automatically issues an alert. At the same time, consumers can scan the code to view the anti-counterfeiting verification result of the traceability code, realizing the anti-counterfeiting function of the traceability label. The consumer query module 8 allows consumers to scan the traceability code on the packaging using a mobile terminal (such as a mobile phone) and jump to the query interface of the traceability management platform 1 to view the full-chain traceability information of the corresponding tea, including tea picking source information, tea purchase transaction information (including POS machine transaction records and card swiping information), tea processing enterprise information, pesticide residue testing information, weighing information, and anti-counterfeiting verification results, achieving the effect of one-scan-to-check and full traceability.

[0025] In this embodiment, the traceability code generated by the traceability code generation and assignment module 6 may also include information such as product batch, packaging time, and shelf life. Furthermore, the traceability code supports offline querying. Consumers can obtain basic traceability information by scanning the traceability code in an offline environment, and can view complete traceability information after connecting to the internet.

[0026] In this embodiment, the distributed database 9, combined with blockchain technology, enables the immutability and traceability of traceability data, ensuring the authenticity and integrity of information at each stage. The data permission management unit 10 assigns different query and operation permissions to different users such as tea farmers, tea purchasing companies, tea processing companies, testing institutions, and consumers to ensure data security.

[0027] In this embodiment, the tea-picking source information collection module 2 can also collect environmental information of the tea garden (such as temperature, humidity, and soil fertility) through IoT devices (such as GPS positioning modules and temperature and humidity sensors), and upload it in conjunction with the tea-picking source information to enrich the dimensions of traceability data.

[0028] In this embodiment, the POS terminal 32 in the tea transaction information collection module 3 supports multiple card swiping transaction methods (such as bank cards, agricultural benefit cards, and mobile payment card swiping). After the transaction is completed, a transaction voucher is automatically generated. The transaction voucher is printed with the corresponding traceability code, which is convenient for both parties to retain and verify. At the same time, the transaction data is synchronized to the traceability management platform 1 in real time, realizing two-way traceability of transaction information and traceability information.

[0029] In this embodiment, the detection information collected by the pesticide residue detection information collection module 5 can also be associated with the qualification certification information of the testing institution. When consumers scan the code to query, they can simultaneously view the relevant qualifications of the testing institution, which enhances the credibility of the pesticide residue detection results. At the same time, if the test results are unqualified, the traceability management platform 1 will automatically lock the corresponding batch of tea, prohibit it from entering the market, and issue a warning message.

[0030] The present invention provides a product end-to-end traceability management method, based on the aforementioned traceability management system, comprising the following steps: S1. Tea Picking Source Information Collection: Through the tea picking source information collection module 2, tea farmer identity information, tea garden location, tea picking time, tea variety, picking batch and other source information are collected and uploaded to the traceability management platform 1 in real time to establish a tea picking source traceability file; S2. Tea Collection Transaction Information: Tea farmers deliver the picked tea leaves to the collection point, where the tea leaves are weighed using a traceability scale 31. The traceability scale 31 collects the weighing data and generates weighing traceability information. The tea collector completes the transaction by swiping a card through a POS terminal 32. The POS terminal 32 records the transaction information (transaction time, amount, identities of both parties, card account, and transaction number), and associates the weighing traceability information and transaction information with the tea source information in step S1, uploading them together to the traceability management platform 1 to establish a tea collection transaction traceability file. The transaction information is encrypted and stored using blockchain technology to ensure it cannot be tampered with. S3. Information collection of tea-frying enterprises: Through the information collection module 4 of tea-frying enterprises, information such as the qualification information, processing equipment information, tea-frying process parameters, processing batches, and processing personnel of tea-frying enterprises is collected and uploaded to the traceability management platform 1. It is then linked with the tea purchase and transaction traceability information of the corresponding batch of tea to establish a traceability file for tea-frying processing. S4. Collection of pesticide residue testing information: After the tea is processed, the testing agency will conduct pesticide residue testing on the tea. Through the pesticide residue testing information collection module 5, information such as testing agency information, testing time, testing items, and testing results will be collected and uploaded to the traceability management platform 1. This information will be associated with the tea processing traceability information of the corresponding batch of tea to establish a pesticide residue testing traceability file. S5. Traceability Code Generation and Assignment: The traceability code generation and assignment module 6 generates a unique traceability code based on the traceability data of the entire process, including tea picking, tea trading, tea processing, and pesticide residue testing, stored in the traceability management platform 1. The traceability code is printed on the tea packaging through the assignment device, so that the traceability code and the tea packaging are matched one-to-one. The traceability code is also bound to the weighing traceability information generated by the traceability scale 31. S6. Anti-counterfeiting treatment: The traceability code on the packaging is subjected to dual anti-counterfeiting treatment through the anti-counterfeiting module 7. The physical layer uses laser engraving and VOID anti-counterfeiting coating, while the digital layer uses the traceability management platform 1 to encrypt the traceability code, record the traceability code query records, and realize abnormal query warning. S7. Consumer Inquiry and Traceability: Consumers can scan the traceability code on the packaging using their mobile devices to access the traceability management platform 1 query interface, view the full-chain traceability information of the corresponding tea (tea picking, tea collection and trading, tea processing, pesticide residue testing), and view the anti-counterfeiting verification results to complete the traceability query; if abnormal information is found or the anti-counterfeiting verification fails, feedback can be provided to the traceability management platform 1 through the query interface.

[0031] Furthermore, in step S2, after the tea purchase transaction is completed, the POS terminal 32 automatically prints a transaction voucher. The transaction voucher contains a traceability code, transaction information, and weighing information, which is convenient for tea farmers and tea purchasing companies to retain and verify. At the same time, the traceability management platform 1 classifies and statistically analyzes the transaction information, supporting tea purchasing companies and regulatory departments to query transaction details.

[0032] Furthermore, in step S5, when generating the traceability code, the national cryptographic SM9 dynamic encryption algorithm is used to ensure the uniqueness and security of the traceability code. The traceability code is also bound to the batch information and packaging information of the tea to avoid confusion between traceability codes of different batches of tea.

[0033] Furthermore, in step S7, when a consumer scans the code to query, the traceability management platform 1 automatically records the query time, the query device model, and the query IP address. If the same traceability code is queried by 3 or more different devices within 1 hour, the system automatically issues an anti-counterfeiting warning and prompts the consumer on the query interface that "the traceability code is abnormal, please verify the authenticity of the product." At the same time, the warning information is pushed to the supervision end of the traceability management platform 1 for the convenience of supervisory personnel to verify.

[0034] The traceability management system and method of this embodiment realize the traceability of tea from the source of tea picking to the end consumer. Information at each link is searchable and traceable, transaction information is deeply bound with traceability information, the traceability code has dual anti-counterfeiting function, and pesticide residue test information can be directly queried through the traceability code. It can effectively ensure the quality and safety of tea, regulate the tea market order, enhance consumer trust, and facilitate its promotion and application in the tea industry.

[0035] It should be understood that in the various embodiments of this application, the order of the above-mentioned processes does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0036] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

A product full-process traceability management system according to claim 1, characterized in that, The consumer query module (8) is used by consumers to scan the traceability code on the packaging through their mobile terminals and jump to the query interface of the traceability management platform (1) to view the full-chain traceability information of the corresponding tea, including tea picking source information, tea collection and transaction information, tea frying enterprise information, pesticide residue testing information, weighing information, and at the same time view the anti-counterfeiting verification results, so as to achieve the effect of scanning and checking and full traceability.

9. A traceability method based on a product full-process traceability management system according to any one of claims 1-8, characterized in that, Includes the following steps: S1. Tea picking source information collection: Through the tea picking source information collection module (2), tea farmer identity information, tea garden location, tea picking time, tea variety, picking batch and other source information are collected and uploaded to the traceability management platform (1) in real time to establish a tea picking source traceability file; S2, Tea collection transaction information collection: Tea farmers deliver the picked tea leaves to the tea collection point, and weigh the tea leaves using a traceability scale (31). The traceability scale (31) collects the weighing data and generates weighing traceability information. The tea collector completes the card transaction through the POS terminal (32). The POS terminal (32) records the transaction information and associates the weighing traceability information, transaction information and the tea picking source information in step S1, and uploads them together to the traceability management platform (1) to establish a tea collection transaction traceability file. The transaction information is stored using blockchain technology for encryption. S3. Information collection of tea-frying enterprises: Through the information collection module (4), information such as the qualification information, processing equipment information, tea-frying process parameters, processing batches, and processing personnel of tea-frying enterprises are collected and uploaded to the traceability management platform (1). The information is then associated with the tea purchase and transaction traceability information of the corresponding batch of tea to establish a traceability file for tea-frying processing. S4. Collection of pesticide residue testing information: After the tea is processed, the testing agency will conduct pesticide residue testing on the tea. Through the pesticide residue testing information collection module (5), the information such as the testing agency information, testing time, testing items, and testing results will be collected and uploaded to the traceability management platform (1) to be associated with the tea processing traceability information of the corresponding batch of tea and to establish a pesticide residue testing traceability file. S5. Traceability code generation and coding: The traceability code generation and coding module (6) generates a unique traceability code based on the traceability data of the entire process, including tea picking source, tea trading, tea processing, and pesticide residue testing, stored in the traceability management platform (1). The traceability code is printed on the tea packaging through the coding device, so that the traceability code and the tea packaging are in a one-to-one correspondence. The traceability code is also bound to the weighing traceability information generated by the traceability scale (31). S6. Anti-counterfeiting treatment: The traceability code on the packaging is subjected to double anti-counterfeiting treatment through the anti-counterfeiting module (7). The physical layer uses laser engraving and VOID anti-counterfeiting coating, and the digital layer uses the traceability management platform (1) to encrypt the traceability code, record the traceability code query records, and realize abnormal query warning. S7. Consumers can scan the traceability code on the packaging with their mobile terminals to jump to the traceability management platform (1) query interface, view the full chain traceability information of the corresponding tea, and view the anti-counterfeiting verification results to complete the traceability query; if abnormal information is found or the anti-counterfeiting verification fails, feedback can be sent to the traceability management platform (1) through the query interface.

10. The traceability method of a product full-process traceability management system according to claim 9, characterized in that, In step S2, after the tea purchase transaction is completed, the POS terminal (32) automatically prints a transaction voucher. The transaction voucher is printed with traceability code, transaction information and weighing information. At the same time, the traceability management platform (1) classifies and statistically analyzes the transaction information, supporting tea purchase enterprises and regulatory departments to query transaction details.
