Description

Technical Field

[0001] This invention relates to the technical field of electronic product recycling and traceability, specifically to a method and system for monitoring the flow of electronic product recycling and traceability that integrates blockchain. Background Technology

[0002] Electronic product recycling traceability and supervision technology integrates IoT, big data, and identification technologies to achieve precise tracking of electronic products throughout their entire lifecycle, ensuring efficient resource recycling and compliant disposal. The core of this system lies in the assignment of unique identifiers, embedded during the electronic product manufacturing process, recording the source of raw materials, production batches, and process parameters. During the recycling stage, the identifier is scanned to activate the traceability process. The system automatically collects equipment information and binds it to the recycling channel, time, and preliminary test data, forming a complete file. Data is stored in a cloud database, using encryption technology for security, and supports real-time updates and multi-terminal access. The supervision function emphasizes two-way traceability: forward tracking allows for tracing the flow of equipment, and reverse tracking allows for locating the source of problems, such as quickly identifying the responsible link in cases of quality defects or illegal dismantling. Technological advantages include improved recycling efficiency and reduced human error; enhanced transparency, allowing consumers to verify recycling compliance; strengthened environmental compliance, meeting stringent regulatory requirements for the management of hazardous substances; and application scenarios covering recycling sites, dismantling plants, and regulatory platforms, helping companies optimize their supply chains and reduce environmental risks. Existing electronic product recycling traceability systems cannot achieve transparent supervision of the entire process from inspection, preparation, and assembly of electronic products, increasing the security risks of illegal dismantling during recycling.

Next, the system and functional information are semantically encoded to obtain a system-functional information semantic understanding feature vector. Then, image features are extracted from the appearance image of the electronic product to obtain an electronic product aging feature vector. Finally, based on the system-functional information semantic understanding feature vector and the electronic product aging feature vector, a recycling assessment value for the electronic product is generated. However, this technical solution fails to provide transparent and traceable information tracking for the hardware repair and maintenance process after electronic device recycling.
