Traceability information uplink and query method and traceability device

Abstract

The invention discloses a traceability information uplink and query method and a traceability device. The method comprises the steps of collecting multiple traceability information elements of an agricultural product, and uploading the traceability information elements to a block chain in real time; acquiring a plurality of traceability information elements from the block chain, the acquired traceability information elements being integrated into a plurality of traceability information entities according to preset associated information, and the traceability information entities carrying block chain IDs corresponding to the traceability information elements; and uploading all the traceability information entities to the block chain. According to the method, a plurality of traceability information elements are sorted into the traceability information entity, and then secondary uplink is carried out, so that repeated and redundant traceability data can be removed from the traceability query result, the authenticity of the traceability data is ensured, and due to the fact that the granularity of the uplink data is increased, the traceability information entity instead of the traceability information element is queried from the block chain, so that the traceability complexity of the user is reduced, the number of times of querying from the block chain is reduced, and the query efficiency and performance are improved.

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...

Problems solved by technology

[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
