no. 1 example ；

[0027] In order to solve the above problems, the present invention provides an embodiment, referring to figure 1 , providing a method for on-chain traceability information, which is applied to the traceability platform, including the following steps:

[0028] S101. The traceability platform collects multiple traceability information elements within the life cycle of agricultural products, and uploads each traceability information element to the blockchain in real time.

[0029] The scheme of the present invention is divided into the process of the first chain-up and the second chain-up. Step S101 executes the process of the first chain-up. Since the traceability information elements of the agricultural products in the life cycle are collected and uploaded (data successfully Stored on the blockchain is called on-chain), the unique blockchain transaction ID generated after the data is on-chain (unless otherwise specified, this method is represented by the blockchain ID), by usin...

[0039] Based on the first embodiment, refer to figure 2 , providing a traceability information query method, applied to the traceability platform, including the following steps:

[0040] S201. The traceability platform queries the traceability information entity of the target from the blockchain.

[0041] S202. The traceability platform obtains corresponding traceability information elements and blockchain IDs from the obtained traceability information entities.

[0042] When receiving the target traceability query from the terminal and performing traceability information query, the traceability information entity is queried from the blockchain instead of the traceability information elements with smaller granularity, which reduces the complexity of user traceability and reduces the complexity of traceability from the blockchain. The number of queries improves query efficiency and performance.

no. 3 example ；

[0044] In order to facilitate those skilled in the art to understand the present invention, refer to image 3 , provides a method embodiment, the method includes the following three steps:

[0045] The first step is the stage of traceability information collection;

[0046] The traceability platform accesses the data of the Internet of Things, or manually enters the data, and each time a new piece of data is collected, it is uploaded to the chain in real time according to the established data structure of traceability information elements. After the block is successfully generated, an immutable transaction record will be generated on the blockchain. At this stage, due to the use of Internet of Things devices to regularly collect information such as pictures, videos, and environments during the operation process, some repetitive and redundant traceability information element data will be stored on the blockchain.

[0047] The second step is the stage of traceability informati...

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...
