[0025] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0026] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] In an exemplary embodiment, Figure 1 As shown, a blockchain-based machine-picked cotton quality traceability method is provided, which specifically includes the following steps, among which:

[0028] Step 201: using a traceability terminal to automatically collect cotton quality parameters and privacy data of the target machine-picked cotton bale at each stage; the stages include cotton harvesting, cotton purchasing, cotton bale opening and processing, and cotton notarization and inspection.

[0029] Step 202: Store the cotton quality parameters and privacy data of the target machine-picked cotton bale at each stage on a blockchain, where the blockchain is used to achieve quality traceability of the target machine-picked cotton bale; the privacy data is encrypted and stored on the blockchain.

[0030] This application integrates IoT automated data collection and blockchain trusted storage, implementing steps 201 to 202 above, effectively resolving issues of data disconnection, data tampering, and privacy leakage throughout the entire process of machine-picked cotton, from field harvesting to seed cotton purchase, lint processing, and notarization inspection. Through the decentralized and tamper-proof nature of blockchain, reliable traceability of cotton quality from cotton growers to lint is effectively achieved, ensuring the authenticity, transparency, and completeness of information at all stages, effectively safeguarding cotton quality and the stability of the industrial chain.

[0031] In another exemplary embodiment of the present application, the blockchain-based machine-picked cotton quality traceability method further includes:

[0032] A quality traceability code is generated for the target machine-picked cotton bale. Each bale has a unique quality traceability code. Specifically, the quality traceability code is written onto the bale's RFID tag, which is embedded in the cotton baling film, by an RFID tag scanning terminal during the cotton baling film production phase.

[0033] The quality traceability code is bound to the cotton quality parameters and privacy data of the target machine-picked cotton bales in each link stored on the blockchain. Specifically, data is obtained through the RFID tag scanning terminal during the harvesting, purchasing, unpacking, processing and notarization inspection links, and uploaded to the blockchain through the Internet of Things device, forming a distributed storage and tamper-proof record of the harvesting data, realizing data binding and distributed storage. The conventional machine-picked cotton quality traceability method does not unify the cotton bale traceability code coding rules. The existing cotton harvesting, purchasing and processing links independently generate heterogeneous identifiers, resulting in the inability to structure the data across links, forming fragmented information islands, and unable to accurately locate the responsible party. In addition, supervision is carried out in the form of checking paper ledgers, which has low supervision efficiency. This application binds the quality traceability code with the data, so that one code can check all links and conduct supervision, which can solve the problems of information islands and inefficient supervision.

[0034] In another exemplary embodiment of the present application, the encrypted storage of private data on the blockchain is specifically as follows:

[0035] The blockchain network consists of multiple nodes, each corresponding to a participant, including cotton farmers, cotton picker operators, processing plants, and notarized inspection agencies. Each node generates public and private keys using an asymmetric encryption algorithm. The public key is used to encrypt private data uploaded to the blockchain, and only the node holding the corresponding private key can decrypt the encrypted data. Data visibility is controlled according to access rights defined in the smart contract. This public and private key mechanism of blockchain nodes ensures data privacy protection and access rights control, ensuring the security and trustworthiness of data during storage and transmission.

[0036] In another exemplary embodiment of the present application, a traceability terminal is used to automatically collect cotton quality parameters and privacy data at each stage of a target machine-picked cotton bale, specifically including:

[0037] The cotton harvesting quality traceability terminal is used to collect cotton quality parameters and privacy data of the target machine-picked cotton bales during the cotton harvesting process.

[0038] The cotton purchasing quality traceability terminal is used to collect cotton quality parameters and privacy data of the target machine-picked cotton bales during the cotton purchasing process.

[0039] The cotton unpacking and processing quality traceability terminal is used to collect cotton quality parameters and privacy data of the target machine-picked cotton bales during the cotton unpacking and processing stage.

[0040] The cotton notarization inspection quality traceability terminal is used to collect cotton quality parameters and privacy data of the target machine-picked cotton bales during the cotton notarization inspection process.

[0041] In another exemplary embodiment of the present application, the cotton quality parameters and privacy data of the target machine-picked cotton bale at each stage are stored on the blockchain, specifically:

[0042] Smart contracts are used to verify the cotton quality parameters and privacy data of target machine-picked cotton bales at each stage. Verified data is stored on the blockchain, and uploaded data is automatically verified using blockchain smart contracts. Once verified, an unalterable traceability record is generated. During the harvesting process, the smart contract verifies data integrity. If any missing or abnormal data is detected, an alarm is immediately triggered and the relevant nodes are notified. During the procurement process, the smart contract also verifies data integrity to ensure that all procurement quality parameters are complete and automatically issues warnings if any anomalies are detected. During the bale opening and processing process, the smart contract verifies the integrity of the uploaded data to ensure data integrity and prevent data falsification or loss. During the notarization and inspection process, the smart contract verifies the integrity of the inspection data to ensure its integrity and fairness.

[0043] In another exemplary embodiment of the present application, before storing the cotton quality parameters and privacy data of the target machine-picked cotton bales at each stage on the blockchain, it also includes: converting the original data collected by different terminals into a unified blockchain storage format through a standardized interface to achieve multi-source heterogeneous data fusion of cotton quality data.

[0044] In another exemplary embodiment of this application, blockchain technology enables quality traceability of target machine-picked cotton bales. When a user initiates a traceability query by entering a quality traceability code, the blockchain smart contract verifies the user's identity, retrieves private data encrypted with the user's public key, decrypts the data using the user's private key, and returns it with a blockchain timestamp. Users can query data records covering the entire cotton production process, from harvesting to processing and notarization inspection, by entering the quality traceability code. Governments and regulatory agencies can use this data to support decisions such as quality control and subsidy issuance, thereby improving management efficiency.

[0045] This application realizes the automated collection and reliable traceability of cotton data throughout the entire process through the collaboration of traceability terminals and blockchain networks. Each cotton bale is embedded with a traceability code during the packaging film production stage, and relies on IoT devices to realize fully automatic data collection and uploading. After conversion through standardized interfaces, it is verified through blockchain smart contracts and uploaded to the distributed ledger of the blockchain. Asymmetric encryption is used to protect data privacy and integrity, and users are supported to query full-process quality data through traceability codes. It involves data collection, storage and traceability of the entire process of cotton from harvesting to processing and inspection. By integrating IoT sensor equipment, radio frequency identification technology, blockchain smart contracts and distributed storage technology, it realizes the automated collection, encrypted storage and tamper-proof traceability of key data in cotton harvesting, unpacking processing, notarization inspection and other links. Through the fusion of multi-source heterogeneous data and the tamper-proof characteristics of IoT technology and blockchain, transparent traceability of the entire process from cotton field harvesting to notarization inspection is realized, solving the problems of information islands and tampering in the traditional industrial chain, and providing transparent and efficient digital support for cotton quality supervision.

[0046] Leveraging the distributed storage capabilities of blockchain, smart contracts automatically verify data authenticity at every stage, triggering the generation of traceability records and supporting the management of data access rights, ensuring the flexibility, security, and privacy of data sharing. The blockchain network utilizes a multi-node distributed structure, with each node storing a complete copy of the data, ensuring data security and immutability during transmission and storage. Asymmetric encryption ensures data security during storage and transmission, ensuring that only authorized users can decrypt and access the data.

[0047] Based on the same inventive concept, the embodiments of the present application also provide a blockchain-based machine-picked cotton quality traceability device for implementing the blockchain-based machine-picked cotton quality traceability method mentioned above. The implementation solution provided by this device is similar to the implementation solution described in the above method. Therefore, the specific limitations of one or more blockchain-based machine-picked cotton quality traceability device embodiments provided below can be found in the above-mentioned limitations of the blockchain-based machine-picked cotton quality traceability method, and will not be repeated here.

[0048] The currently published automatic quality data collection system for cotton in the harvesting stage and the online precise integrated detection system for seed cotton moisture regain and impurity content in the cotton harvesting link have not well introduced blockchain technology to solve the problems of data disconnection and privacy leakage in the cotton industry chain in the existing technology. Based on this, the present application provides a blockchain-based machine-picked cotton quality traceability device, including: a traceability terminal for automatically collecting cotton quality parameters and privacy data of target machine-picked cotton bales in each link, and storing the cotton quality parameters and privacy data of the target machine-picked cotton bales in each link on the blockchain, the blockchain is used to achieve quality traceability of the target machine-picked cotton bales; the privacy data is encrypted and stored on the blockchain; the links include cotton harvesting link, cotton purchasing link, cotton bag opening and processing link and cotton notarization and inspection link.

[0049] In another exemplary embodiment of the present application, the blockchain-based machine-picked cotton quality traceability device also includes: an RFID tag, which is set in the target machine-picked cotton bale, and the quality traceability code of the target machine-picked cotton bale is written into the RFID tag, and the quality traceability code is bound to the cotton quality parameters and privacy data of the target machine-picked cotton bale in each link stored on the blockchain.

[0050] In another exemplary embodiment of the present application, the tracing terminal includes:

[0051] The cotton harvesting quality traceability terminal is used to collect cotton quality parameters and privacy data of target machine-picked cotton bales during the cotton harvesting process.

[0052] The cotton purchasing quality traceability terminal is used to collect cotton quality parameters and privacy data of target machine-picked cotton bales during the cotton purchasing process.

[0053] The cotton bale opening and processing quality traceability terminal is used to collect cotton quality parameters and privacy data of the target machine-picked cotton bales during the cotton bale opening and processing stage.

[0054] The cotton notarization inspection quality traceability terminal is used to collect cotton quality parameters and privacy data of the target machine-picked cotton bales during the cotton notarization inspection process.

[0055] The cotton harvesting quality traceability terminal, cotton purchasing quality traceability terminal, cotton packaging and processing quality traceability terminal, and cotton notarization and inspection quality traceability terminal are all connected to the industrial computer, which uploads the collected data to the blockchain through the data bus.

[0056] This application uses cotton harvesting quality traceability terminals, cotton purchasing quality traceability terminals, cotton packaging and processing quality traceability terminals, and cotton notarization and inspection quality traceability terminals, combined with blockchain networks and Internet of Things devices, to achieve automated data collection and traceability for the entire process of machine-picked cotton from harvesting, purchasing, packaging and processing to notarization and inspection.

[0057] In actual applications, cotton quality parameters for target machine-picked cotton bales during the cotton harvest process include: harvest time, harvesting plot location, cotton picker information (license plate number, serial number, and brand), cotton moisture regain, and trash content. Private data collected during the cotton harvest process includes: cotton farmer identity information, cotton picker driver identity information (driver name and contact information), harvested area, and harvesting price (determined by the cotton picker driver and the cotton farmer). The cotton harvesting quality traceability terminal includes: an ID card reader (for collecting cotton farmer identity information); a Beidou positioning device (for collecting harvesting plot location); a moisture regain sensor (for collecting cotton moisture regain), and a trash content camera (for collecting trash content). Harvest time, cotton picker information, cotton picker driver identity information, harvested area, and harvesting price can be manually input directly into an industrial computer.

[0058] In practice, the machine-picked cotton quality traceability system can also record cotton picker information and driver identity information and register it as a trusted node in the blockchain network. The system then uploads this information to an industrial computer. The computer's built-in algorithm calculates the harvested area based on the harvesting plot locations collected by the Beidou positioning system. A first RFID tag scanning terminal is installed above the cotton picker's baling belt to scan the cotton bale traceability code. When the bale traceability code is scanned, the time of harvest is uploaded to the industrial computer as the harvest time.

[0059] In another exemplary embodiment of the present application, the industrial computer is also connected to the vehicle-mounted display screen to display the harvesting operation parameters (harvesting time, harvesting plot location, cotton picker information (license plate number and serial number), cotton regain and impurity content, harvesting area) and geographic coordinate information in real time on the vehicle-mounted display screen to ensure the visualization of the harvesting process and the real-time nature of the data.

[0060] In practical applications, cotton quality parameters for target machine-picked cotton bales during the cotton purchasing process include: purchase weight, purchase time, trash content, moisture regain, length, lint content, micronaire value, and specific breaking strength. Private data collected during the cotton purchasing process includes: purchase price, payment information, and farmer identity information. The cotton purchase quality traceability terminal includes a seed cotton rapid quality detection system (for collecting trash content, moisture regain, length, lint content, micronaire value, and specific breaking strength) and a weighing system (for collecting purchase weight and purchase time). The purchase price, after negotiation between the cotton farmer and the processing plant, can be uploaded directly to the industrial computer or entered by the processing plant operator through the machine-picked cotton quality traceability system, which then uploads the entered purchase price to the industrial computer. The industrial computer can collect payment information in real time through a data interface with the payment platform or bank system and automatically upload it to the blockchain network. Farmer identity information can also be entered manually. The specific usage process is as follows: the name, address, number and person in charge information of the processing plant are entered through the machine-picked cotton quality traceability system, and registered as a trusted node in the blockchain network. Cotton farmers make appointments with the processing plant through the machine-picked cotton quality traceability system. When purchasing, the cotton quality parameters and privacy data of the target machine-picked cotton bales in the cotton purchasing link are obtained through the above means, and uploaded to the blockchain through the industrial computer to ensure that the quality of the purchased cotton meets the standards.

[0061] In actual applications, a second RFID tag scanning terminal can be installed above the floor scale weighing system to bind the scanned cotton bale traceability code with data such as the weight unit price of the processing factory's own seed cotton purchasing system.

[0062] In actual applications, the cotton quality parameters of the target machine-picked cotton bales during the cotton unpacking process include: processing batch number, equipment parameters, transit time, unpacking location, moisture regain, trash content, length grade, color grade, and ginning quality. The private data of the target machine-picked cotton bales during the cotton unpacking process includes: processing cost, processing parameters, equipment maintenance records, and processing personnel information. The cotton unpacking and processing quality traceability terminal includes: an online seed cotton detection device (for collecting moisture regain, trash content, and color grade) and an online lint cotton detection device (for collecting moisture regain, trash content, color grade, length grade, and ginning quality). The processing batch number can be directly generated by the online seed cotton detection device or the online lint cotton detection device. Equipment parameters, equipment maintenance records, transit time, unpacking location, processing personnel information, processing parameters, and processing costs can be manually input directly into the industrial control computer.

[0063] In actual applications, a third RFID tag scanning terminal can be set up on the transfer forklift or bale opener station to scan the cotton bale traceability code to establish an associated binding for the processing link. When the cotton bale traceability code is scanned, the cotton bale is marked to enter the bale opening processing link, and the transfer time and bale opening location are recorded. The processing personnel information and processing process parameters are entered by the processing plant operator through the machine-picked cotton quality traceability system. The machine-picked cotton quality traceability system uploads the entered processing personnel information and processing process parameters to the industrial computer. The processing cost is collected by the financial system data interface and uploaded directly to the industrial computer.

[0064] Specifically: The seed cotton online detection device is set at the front end of the production line, mainly detecting the seed cotton's impurity content, moisture regain, color grade and other quality indicators; the lint cotton online detection device is set at the end of the production line, mainly detecting the lint cotton's color grade, moisture regain, length, impurity content and other quality indicators to ensure quality monitoring and data traceability during the processing process.

[0065] In practical applications, cotton quality parameters for the target machine-picked cotton bale during the cotton notarization inspection process include moisture regain, trash content, color grade, length grade, micronaire grade, and specific breaking strength. The private data collected during the cotton notarization inspection process includes inspector information and inspection equipment maintenance records. The notarization inspection quality traceability terminal includes a cotton fiber tester, which collects cotton quality parameters for the target machine-picked cotton bale during the cotton notarization inspection process. The private data collected during the cotton notarization inspection process can be manually input directly into an industrial computer.

[0066] In actual application, the inspector information is entered into the machine-picked cotton quality traceability system, and then the machine-picked cotton quality traceability system uploads the entered inspector information to the industrial computer. The inspection equipment maintenance records are regularly updated by the maintenance personnel and then directly uploaded to the industrial computer manually.

[0067] The specific working process is as follows: in the notarization and inspection link, first register the name of the notarization and inspection agency, the inspection date and the inspection equipment number in the blockchain network; then obtain the cotton quality parameters and privacy data of the target machine-picked cotton bales in the cotton notarization and inspection link through the above means, and upload them to the blockchain through the industrial computer and bind them with the cotton traceability code.

[0068] In another exemplary embodiment of the present application, the blockchain-based machine-picked cotton quality traceability device also includes: a notarized RFID tag scanning terminal for reading the traceability code of the cotton bale to ensure the correspondence between the sample and the original cotton bale, and a cotton fiber tester for detecting quality indicators such as the regain, impurity content, color grade, length grade, micronaire grade and breaking strength of the cotton sample to provide a comprehensive quality assessment.

[0069] In another exemplary embodiment of the present application, the blockchain-based machine-picked cotton quality traceability device also includes: a data processing system, which integrates the cotton quality parameters of the target machine-picked cotton bales in the cotton notarization inspection link, generates notarization inspection data, and uploads it to the quality traceability platform through the Internet, thereby realizing real-time sharing and traceability of cotton quality data, and ensuring the fairness and transparency of cotton transactions.

[0070] This application is based on blockchain technology, which ensures the authenticity and transparency of cotton quality data and effectively eliminates the problems of information tampering and false data in traditional traceability systems. Through the decentralized nature of blockchain, it ensures that data cannot be tampered with once entered, providing users with reliable data protection. With the help of smart contracts, it realizes the automation of data entry, verification and storage, greatly improving traceability efficiency. Through data sharing among participating parties (such as production enterprises, processing enterprises and regulatory agencies), mutual trust in the supply chain is enhanced. It meets the needs of multiple parties such as consumers and regulatory agencies, supports the query and verification of cotton quality data, and has wide applicability.

[0071] The working process of the blockchain-based machine-picked cotton quality traceability method provided in this embodiment is as follows: Figure 2 The specific steps are as follows:

[0072] like Figure 3 As shown, before cotton is harvested, each cotton bale is pre-attached with a uniquely identified RFID chip as an RFID tag. This tag is generated using standardized coding rules and includes an anti-counterfeiting checksum to ensure the uniqueness and security of the quality traceability code. Cotton picker drivers are required to register through the cotton harvesting quality traceability terminal, entering their identity information and cotton picker information. During the cotton harvesting process, an ID card reader reads the cotton farmer's identity information, and a Beidou positioning system is used to obtain the field location in real time. A moisture regain sensor and trash content camera installed on the cotton picker collects moisture regain and trash content data in real time, and images of the harvested cotton are recorded. Simultaneously, a first RFID tag scanning terminal scans the RFID chip and binds the cotton bale traceability code. All data is uploaded to the blockchain node via an industrial computer and displayed on the vehicle's display screen. Private data, such as the farmer's identity, the picker driver's identity, the harvested area, and the harvesting price, is encrypted and uploaded to form a complete record chain that can be queried at multiple nodes, ensuring authenticity and transparency.

[0073] like Figure 3As shown, during the procurement process, cotton farmers use the machine-picked cotton quality traceability system to make advance reservations with the processing plant and arrange procurement. Once the cotton arrives at the processing plant, cotton inspectors use the seed cotton rapid quality testing system to test the cotton for quality information such as trash content, moisture regain, length, lint percentage, micronaire value, and specific breaking strength. During procurement, a weighing system measures the cotton. A second RFID tag scanning terminal on the gantry pole controls the RFID tag scanning terminal antenna to read the RFID electronic chip to obtain the cotton bale traceability code. Key data such as the procurement time and location are recorded, and the inspection quality data is linked to the cotton weight. This data is automatically verified for integrity by a blockchain smart contract and stored on the blockchain network. Privacy information such as the purchase price, payment information, and farmer identity information is encrypted and uploaded to ensure transparency and security.

[0074] like Figure 3 As shown, during the bale opening process, when the cotton bale transfer forklift transports the cotton bale to the opening location, a control button is pressed, which controls the third RFID tag scanning terminal to read the RFID electronic chip on the cotton bale. Upon successful reading, a voice reminder device and LED indicator light provide corresponding prompts. The industrial computer records the processing batch number, equipment parameters, the time of transfer into the processing flow, and the location of the bale opening. During processing, online seed cotton and lint cotton inspection devices monitor cotton quality parameters in real time, including moisture regain, trash content, length grade, color grade, and rolling quality. All data from the bale opening process is uploaded to the blockchain network in real time. Private data such as processing costs, processing parameters, equipment maintenance records, and processing personnel information is encrypted and uploaded. Smart contracts perform integrity checks on the uploaded data to ensure data integrity and immutability. Ultimately, the blockchain network forms a complete chain from cotton bale storage to processing completion, enabling efficient data traceability and information security throughout the entire process.

[0075] like Figure 3 As shown in the notarized inspection process, processed lint cotton undergoes quality inspection by a notarized inspection agency. Inspection data, including moisture regain, trash content, color grade, length grade, micronaire grade, and specific breaking strength, is uploaded to the blockchain network in real time via the inspection organization's nodes. Private data, such as inspector information and inspection equipment maintenance records, is encrypted and linked to the bale's traceability code. Thanks to the blockchain's tamper-proof nature, all inspection data possesses a high degree of credibility. Cotton farmers and regulatory authorities can use the traceability code to accurately access information from harvest to inspection, ensuring that inspection results are accurately linked to the actual grower.

[0076] By entering the quality traceability code, users can access the entire process of cotton harvesting, processing, and notarized inspection on the machine-picked cotton quality traceability system. This data includes plot information, harvest quality data, procurement records, processing information, and inspection results. Leveraging the blockchain's immutability and full-process traceability, this system ensures efficient cotton quality traceability and provides government agencies with data-driven decision-making support, such as the issuance of subsidies for high-quality cotton cultivation and market supervision. This improves transparency and management efficiency in the cotton industry, while also promoting its digitalization and high-quality development.
