A traceability information chain, query method and traceability equipment

Abstract

The invention discloses a traceability information uplink and query method and traceability equipment. The method includes: collecting multiple traceability information elements of agricultural products, and uploading them to the block chain in real time; obtaining several traceability information elements from the block chain, and integrating the acquired traceability information elements into several traceability information according to preset associated information entity, and the traceability information entity carries the blockchain ID corresponding to each traceability information element; upload all traceability information entities to the blockchain. The present invention integrates several traceability information elements into traceability information entities, and then carries out the method of secondary chaining, which can not only remove redundant traceability data in the traceability query results, but also ensure the authenticity of the traceability data, and Because the granularity of the data on the chain becomes larger, the traceability information entity rather than the traceability information element is queried from the blockchain, which reduces the complexity of user traceability, reduces the number of queries from the blockchain, and improves query efficiency and performance. .

Description

technical field [0001] The invention relates to the technical field of traceability of agricultural products, in particular to a traceability information uploading and query method and traceability equipment. Background technique [0002] The current blockchain-based agricultural product traceability platform, in order to ensure the credibility of the data source, on the one hand, directly connects with the Internet of Things, and uploads the traceability information elements collected by the Internet of Things to the chain in real time; on the other hand, the operators input the traceability information elements in real time during the operation And carry on the chain. [0003] However, for agricultural products that have a long cycle from planting to sales, each link will generate a large amount of traceable information element data, such as agricultural operation records in the planting link, meteorological environment data, soil data, etc. If these data are collected thr...

[0003] However, for agricultural products that have a long cycle from planting to sales, each link will generate a large amount of traceable information element data, such as agricultural operation records in the planting link, meteorological environment data, soil data, etc. If these data are collected through the Internet of Things or operators Real-time on-chain will inevitably generate some duplicate and redundant data, and the data collected on-chain will be relatively disordered, which increases the complexity of obtaining useful information and reduces the efficiency of traceability
