Block chain technology-based food supply chain management system

Abstract

The invention relates to the technical field of block chains, in particular to a block chain technology-based food supply chain management system, which comprises an intelligent shopping cart and an information processing module; shopping baskets of the intelligent shopping cart are divided into code-scanned shopping baskets and code-unscanned shopping baskets, the code-scanned shopping baskets are provided with acquisition devices and display devices, and the bottoms of the code-scanned shopping baskets are provided with first weight detection modules used for measuring weight data of commodities in the code-scanned shopping baskets; the system also comprises anacquisition device and an information processing module; the acquisition device is used for scanning commodity bar codes and acquiring commodity information and movement direction information of commodities; and the information processing module judges whether the user puts the scanned commodity into the scanned shopping basket or not according to the movement direction information of the scanned commodity, if not, triggers the display device to remind, and judges whether the user scans the commodity before putting the commodity into the scanned shopping basket or not according to the weight data, and if not, triggers the display device to remind. According to the scheme, the user can be reminded to weigh the commodity needing to be weighed, and the shopping experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of block chain, in particular to a food supply chain management system based on block chain technology. Background technique [0002] The food supply chain is a whole composed of economic stakeholders from primary food producers to consumers. The food supply chain generally includes: primary production link, food processing link, food marketing link and logistics link. With the development of society, the complexity of the food supply chain has become higher and higher, so it is difficult to ensure the authenticity and safety of products in the entire supply chain, and many food safety problems have emerged. With the emergence of blockchain technology, people apply blockchain technology to food traceability due to its transparency, difficulty in tampering, traceable audit, and decentralization to solve food supply problems. chain complex issues, and to achieve comprehensive security monitoring of the food ...

Problems solved by technology

However, there are some problems in the shopping experience in the current supermarkets. For example, for some products that need to be weighed in the supermarket, if the user forgets to weigh them, he will go to the cashier to pay, and the user needs to return to weigh or give up buying the product. Especially when there are many people queuing up at the checkout counter, if the user turns back to weigh, they need to queue up again, which greatly wastes the user's time, reduces the efficiency of the supermarket's checkout, and leaves a bad shopping experience for the user.
