Waste electric appliance recycling tracing system and method based on block chain technology

Abstract

The invention discloses a waste electric appliance recycling tracing system and method based on a block chain technology. A block chain technology is used, and a waste electric appliance generation source, a waste electric appliance transportation enterprise, a waste electric appliance recovery enterprise, a waste electric appliance processing enterprise and other nodes involved in the traceability system can be used as trusted nodes in a block chain; on this basis, an alliance chain is established, a decentralized waste electric appliance recycling traceability system and a corresponding recycling platform APP are developed on the basis, each node enterprise records data of each process through the recycling platform APP and uploads the data to a background database, and after all waste electric appliance recycling chains are completed, the data is recorded and stored through a smart contract and the block chain, so that each node has the same data account book, and the storage security problem of the traceability data is solved. The real management and tracing effects are achieved, and the problems that recycling, delivery and handover records are not clear, and the flow direction is difficult to trace are solved.

Description

technical field [0001] The invention belongs to the field of electronic product recycling. Based on the recycling process of waste electrical appliances, the various links of waste electrical appliances recycling are connected through the block chain, and the information generated by each link is summarized and fed back, so as to realize the recycling of waste electrical appliances. Traceability of the recycling process. Background technique [0002] With the social and economic development and scientific and technological progress in our country, more and more electrical and electronic products have entered the family and office life. At the same time, the replacement cycle of products is getting shorter and shorter, and the generation of waste electrical and electronic products in my country is increasing rapidly. Studies have shown that the growth rate of electronic waste is 3-5 times the average growth rate of municipal solid waste, and it is increasing at a rate of 5%-8...

AI Technical Summary

Problems solved by technology

The present invention mainly uses block chain technology to solve the storage safety problem of data generated during the recycling process of waste electrical appliances. At present, the recycling process of waste electrical appliances lacks corresponding traceability means, and there is no record or unclear records for recycling, delivery and handover. Waste electrical appliances It is difficult to trace the flow of waste electrical appliances, and the traditional waste electrical appliances recycling traceability system is generally a centralized platform system. The data records of the entire waste electrical appliances recycling process are usually controlled by the platform provider, and there is a security problem of data tampering
