Cold chain transportation and temperature intelligent control method based on block chain

Abstract

The invention relates to a cold-chain transportation and temperature intelligent control method based on a block chain, and the method comprises the steps that a manufacturer issues a shipment task, and a logistics party receives the task and distributes the task according to a destination; the factory records the commodity information and uploads the commodity information to the system; the logistics vehicles are bound with the task numbers, and a block chain system is called for the vehicle transportation environment, temperature, track and time through an interface and the vehicle transportation environment, the temperature, the track and the time are uploaded in real time; a temperature self-control alarm device is started in the transportation process; the sales terminal records and uploads the receiving time, the commodity quantity and the commodity validity period information to the system; a client, a logistics terminal and a sales terminal inquire commodity traceability information in real time through a system or a client; a consumer obtains traceability information of shipment, transportation and receiving by scanning the two-dimensional code of the electronic screen. According to the invention, through the blockchain and Internet of Things technologies, the data of the whole process from warehouse-out to cold-chain transportation to sales of commodities is recordedand stored in the blockchain system, and all the data is maintained by multiple parties, so that the safety of the whole transportation process of purchased articles is ensured.

Description

technical field [0001] The invention belongs to the technical fields of Internet of Things, blockchain and cold chain, and specifically relates to an intelligent control method, especially a blockchain-based cold chain transportation and intelligent temperature control method. Background technique [0002] After the goods leave the warehouse, they are transported through the cold chain and then arrive at the sales terminal. In order to better ensure the quality of the goods, it is necessary to track and record the goods in the whole process, recording the information of the goods from the beginning of shipment, and recording and uploading the environment of the goods in real time during the logistics process. , and then go to the sales terminal receipt record to upload product information. [0003] At present, in the process of production, transportation and sales, information is stored in a single system, which will lead to when the ledger information is unfavorable to the ...

Problems solved by technology

[0003] At present, in the process of production, transportation and sales, information is stored in a single system, which will lead to when the ledger information is unfavorable to the participants, the participants tamper with the ledger or falsely claim that the ledger is lost due to technical reasons; and the goods cannot be dynamically controlled during the transportation process. , it is difficult to ensure the safety of commodity transportation; at the same time, due to the poor interaction between single systems and inconsistent access to data permissions, it will lead to cumbersome and repeated audits when checking account book information, which will increase the workload, increase the cost, and the authenticity of the data cannot be guaranteed.
