A blockchain-based cold chain traceability system

Abstract

The present invention relates to a blockchain-based cold chain traceability system, including: an intelligent terminal device, which can send the entrusting party's demand information actively provided by the entrusting party to The block chain node unit, or to send the product identification information it recognizes to the block chain node unit when it accesses the block chain node unit by identifying the product identification mark; the cloud computing server is used to receive the At least one of the status information in the turnover equipment collected by the block chain node unit, the entrusting party's demand information and product identification information is analyzed in combination with the stored comprehensive database and at least one cold chain logistics plan and / or obtained from it Or at least one reference cold chain logistics solution is output to at least one block chain node unit that can be accessed by the first intelligent terminal device, the second intelligent terminal device or the third intelligent terminal device according to the corresponding user authority.

Description

technical field [0001] The invention relates to the technical field of cold chain transportation, in particular to a blockchain-based cold chain traceability system. Background technique [0002] Cold Chain Logistics (Cold Chain Logistics) generally refers to a systematic project in which refrigerated and frozen foods are always kept in a specified low temperature environment in all links of production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. . At present, most cold chain logistics monitoring technologies are very mature, but the difficulty lies in the traceability of data in the supply chain. Because a product involves multiple companies (logistics companies, warehousing companies) in the logistics link, it is very troublesome to integrate and exchange data between companies in these chains. Without the integration of these data, traceability cannot be achieved. Blockchain is very reliable for traceability data records...

Problems solved by technology

[0009] Aiming at the problem that it is difficult to monitor the temperature control environment of the cold chain transportation process in the current field, the patent literature with the publication number CN110458491A and the patent literature with the publication number CN106548319A in the prior art respectively propose a cold chain Logistics monitoring system, in the process of transportation, mainly adopts technologies such as the centralized structure of supply chain logistics proposed by the cold chain special box combined with the conventional cold chain transportation mode

Although this kind of centralized structure of traditional supply chain logistics is beneficial to solve the problem of temperature control environment in the process of cold chain transportation, at present, due to the lack of unified management of the decentralized logistics system in this kind of structure, the information is messy and scattered, which leads to disputes among users of all parties. It is difficult to produce credible evidence, and the cost of accountability is high and difficult, requiring a lot of manpower and material resources

Once problems such as temperature exceeding the limit during a certain period of time during the transportation process occur, it is impossible to self-certify whether there is any technical deviation caused by transportation or the environment during the cold chain transportation process, and the customer cannot monitor and detect whether the cold chain transportation link is in accordance with the current structure standard conduct
