Intelligent cold chain system based on block chain and method thereof

Abstract

The invention discloses an intelligent cold chain system based on a block chain and a method thereof, and the system comprises: a cold chain product monitoring and management subsystem based on the block chain, and the subsystem monitors the validity period of a cold chain product and the storage place and storage temperature in the whole process of cold chain logistics in real time, and achievesthe monitoring and management of the cold chain product; the cold-chain logistics monitoring management subsystem based on the block chain, wherein the subsystem monitors the position, storable capacity, product requirements, storage temperature and other information of a cold-chain storage facility in real time; the cold chain information unified management subsystem based on the block chain andused for unified management and storage of cold chain information in the two subsystems; and the cold chain information query application subsystem that is used for realizing cold chain information query of the user. And in combination with other structures and methods, the defect that in the prior art, data of a cold chain data management scheme is easily maliciously tampered, so that unqualifiedcold chain logistics commodities enter the market, and consumers difficultly judge whether purchased products have quality problems or not from the appearance of the products is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent cold chain, and also belongs to the technical field of block chain and Internet of Things, and specifically relates to a block chain-based intelligent cold chain system and its method. Background technique [0002] Cold chain logistics generally refers to a systematic project in which refrigerated and frozen items are always kept in a specified low temperature environment in all links of production, storage, transportation, sales, and consumption to ensure the quality and performance of the items. It was established with the advancement of science and technology and the development of refrigeration technology. It is a low-temperature logistics process based on refrigeration technology and using refrigeration technology as a means. In other words, the cold chain is a low-temperature logistics process established with the advancement of science and technology and the development of refrigeration...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a block chain-based smart cold chain system and its method, which combines block chain and Internet of Things technology, and introduces the concept of block chain life cycle to solve the problem of data being maliciously The problems of tampering, increasing difficulty of blockchain consensus and slow running speed effectively avoid the cold chain data management scheme data in the existing technology being easily tampered with maliciously, causing unqualified cold chain logistics products to enter the market, and consumers are affected by the appearance of the product. It is difficult to judge whether the purchased product has defects of quality problems
