Commodity circulation monitoring method, node equipment and block chain system

Abstract

The invention discloses a commodity circulation monitoring method, node equipment and a block chain system, and the method comprises the steps: obtaining admission product information when a commodityenters the market, and enabling the admission product information to serve as a head block of a block chain; obtaining first circulation information and second circulation information of the commodity at two opposite circulation nodes, and comparing the first circulation information with the second circulation information to obtain first comparison data; forming a data block according to the first comparison data, and taking the data block as an intermediate block of the block chain; obtaining a plurality of intermediate blocks formed in the circulation process of the commodity, and arrangingthe plurality of intermediate blocks according to a time sequence; comparing the plurality of intermediate blocks with preset food safety data to obtain second comparison data; and obtaining processing data according to the second comparison data, and taking the processing data as a tail block of the block chain. According to the invention, each circulation node of commodity transaction can be effectively monitored, the safety of commodities is effectively improved, and the efficiency of commodity problem tracing is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent management, in particular to a commodity circulation monitoring method, node equipment and a block chain system. Background technique [0002] The food safety of commodities, especially agricultural products, is related to national health and physical fitness. At present, most agricultural products are highly dependent on agricultural product trading markets, including agricultural batch markets or farmers' markets, for distribution, trading and circulation. The large dispersion and large span in time and space between the source planting of agricultural products and the final consumption also makes it extremely difficult to realize the food safety management of the whole chain and the whole process of each agricultural product from source to consumption in practice, and the resource and cost requirements are also extremely high , is not operable. [0003] The current relevant technologies r...

AI Technical Summary

Problems solved by technology

The large dispersion and large span in time and space between the source planting of agricultural products and the final consumption also makes it extremely difficult to realize the food safety management of the whole chain and the whole process of each agricultural product from source to consumption in practice, and the resource and cost requirements are also extremely high , not operable

[0003] The current related technology related to the traceability of the whole chain and whole process of food safety is only the information disclosure of the whole chain and whole process of food or agricultural products, which belongs to the display of results, and cannot achieve process management

The current related technologies are mainly to manually enter food safety-related information through the producers at the source of production, or employees in agricultural product trading markets including agricultural wholesale markets or agricultural products markets, and unilaterally participate in control, resulting in food safety testing results being affected by human intervention. bigger
