Embodiment 1

[0051] Obtain product production information through the factory module. Specifically, product production information includes management personnel information, product production date, product delivery date, processing personnel information, product quality performance value total, weight information, inspector and inspection date;

[0052] Exemplarily, by establishing a data connection with the factory where the supply chain query management system is installed, the management personnel information of the product can be obtained, where the management personnel information can be the person in charge of the area, and this disclosure does not make specific requirements here; the production date and delivery date The date is the only date; the total weight information is the weight of the product after processing and waiting for transportation;

[0053] It should be noted that the above-mentioned management personnel information, product production date, product delivery date, p...

Abstract

The invention belongs to the field of product supply chain query and relates to block chain technology, which is used to solve the problem that the circulation information of product quality is less, and at the same time, because the traditional product query method relies on the Internet, the information data can be arbitrarily tampered with, resulting in low traceability reliability. The problem is specifically a blockchain-based product supply chain query management device and method, including a query management platform for generating a block tree, a factory module for recording product production information, a transportation module for recording product logistics information, and A sales module for recording product sales information. The block tree includes a block trunk, several block branches, and several block leaves. Several block branches are distributed on the block trunk, and several block leaves are distributed on the block branches; The present invention ensures data security by setting that only the storage information of the block branch can be obtained through the block leaf, and the block branch can only obtain the storage information of the main block.

Description

technical field [0001] The invention belongs to the field of product supply chain query and relates to block chain technology, in particular to a block chain-based product supply chain query management device and method. Background technique [0002] Product supply chain refers to the sequence of links and operations from primary production to consumption, involving the production, processing, distribution, storage and handling of products and their auxiliary materials, ranging from raw material producers, product manufacturers, transporters and warehousers , subcontractors to retailers and product service links and related organizations, such as equipment, packaging material producers, cleaning industries, additives and ingredients producers. [0003] In order to improve consumers' product safety experience, product manufacturers attach a QR code containing the manufacturer's information and the origin of agricultural products to the product packaging. After purchasing the ...
