Description

Cold chain agricultural product management method and device based on block chain Technical Field The application relates to the technical field of blockchain, in particular to a method and a device for managing cold chain agricultural products based on blockchain. Background Agricultural products, particularly fresh and perishable agricultural products, need to go through a series of storage, transportation and distribution links after being harvested from the production area to finally reach the consumers. In order to ensure the quality, freshness and food safety of agricultural products, to reduce the loss during circulation, cold chain logistics have been developed and play a vital role. The complete cold chain system requires that the agricultural products are always in a specific low temperature environment throughout the supply chain link to inhibit microbial activity and biochemical changes. In the prior art, management of cold chain agricultural products has typically relied on a centralized management system. For example, a logistics company or a warehouse center may record information of goods coming in and going out, transportation routes, and sporadic data collected by a temperature sensor using its own database. However, such conventional management modes have many inherent drawbacks, such as opaque information and information islands, easy tampering of data, high trust cost, difficult tracing, and low supervision efficiency. To address some of the issues, some approaches introduce internet of things (IoT) technology to collect environmental data in real time by installing temperature, humidity, etc. sensors on a vehicle or package. However, such data is still typically uploaded to a centralized server, and the problems of data trust and transparency are not fundamentally addressed. In recent years, the blockchain technology provides a new thought for solving the trust problem in supply chain management by virtue of the characteristics of decentralization, non-falsification of data, transparency disclosure and traceability. The prior art attempts to use blockchain for product tracing, and the key link information record of the product is used for linking up so as to realize anti-counterfeiting and tracing. However, most of these applications stay at the static record level of information and do not really meet the management needs of cold chain agricultural products. Disclosure of Invention The application provides a block chain-based cold chain agricultural product management method and a block chain-based cold chain agricultural product management device, which not only can ensure the authenticity and traceability of the whole flow data of the cold chain agricultural products, but also can dynamically and intelligently evaluate the quality of products in the transportation process, and realize the automation of transaction and supervision based on evaluation results, thereby comprehensively improving the transparency, efficiency and safety of the cold chain management. The application provides a method for managing cold chain agricultural products based on blockchains, which comprises the steps of mapping the cold chain agricultural products in the physical world into target tokens on blockchains at a production place node, transferring the target tokens to blockchain addresses associated with logistics transportation means, periodically collecting state data of the cold chain agricultural products at the cold chain transportation node, processing the state data through a pre-trained intelligent model, generating quality ratings of the cold chain agricultural products, packaging the quality ratings and other verification data into data packets, and uploading the data packets to the blockchain addresses corresponding to the logistics transportation means, continuously monitoring the quality ratings of the uplinks through intelligent contracts until the target tokens are transferred into the blockchain addresses of a distributed node, and waiting for users to purchase the cold chain agricultural products at the distributed node. According to the block chain-based cold chain agricultural product management method provided by the application, after a collection node waits for a user to purchase the cold chain agricultural product, the method further comprises the steps of transferring a target token to a retail node address representing the user after the cold chain agricultural product finishes delivery to the user on line, marking the state of the target token as sold through an intelligent contract, and closing a circulation function. According to the cold chain agricultural product management method based on the blockchain, the quality rating of the uplink is continuously monitored through the intelligent contract, and the method comprises the steps of triggering freezing operation to lock or limit the circulation function of target tokens under the blockchain address of a logistics transpor
