Abstract

The invention relates to the technical field of data application, in particular to a tracing method, a tracing system and a storage medium based on agricultural products. The method comprises the steps of obtaining Nth-level ticket data of a second user for supplying first edible agricultural products, generating a mother ticket according to all or part of the Nth-level ticket data, generating N+1th-level ticket data based on the identity data of the first user, generating a first sub-ticket according to all or part of the N+1th-level ticket data and data set, embedding a source ticket and the mother ticket into the first sub-ticket to obtain a second sub-ticket, and storing the second sub-ticket into a cloud database. In the invention, by establishing a dynamic and chain type data structure of the sub-ticket embedded parent ticket and the source ticket, the traceability information is not an isolated fragment any more, but is automatically split and carries all father genes along with the splitting of a real object, thus thoroughly solving the information breakage problem caused by ticket-cargo separation.

The agricultural product-based tracing method of claim 1, wherein said identity data comprises any one of or a combination of the following: Unique identifier allocated after real name authentication; Official registration name and corresponding legal identity code; mobile communication terminal number with real name binding.
3. The agricultural product-based tracing method of claim 1, wherein said data set comprises at least a physical quantity of said first edible agricultural product measured during the current circulation, and image or video data collected during the circulation comprising visual information of said first edible agricultural product.
4. The agricultural product-based tracing method of claim 1, wherein said data set further comprises environmental data collected by said intelligent tracing terminal or its associated device, said environmental data comprising one or more of transaction time, transaction geographic location information, environmental temperature.
5. The agricultural product-based tracing method of claim 1, wherein said source ticket is a parent ticket generated from level 1 ticket data.
6. The agricultural product-based tracing method of claim 5, wherein said second user ticket data level determining step comprises: S31, acquiring a historical second sub-ticket associated with the second user stored in the cloud as a historical purchasing party; s32, based on ticket embedded relation, starting from the second historical sub-ticket, tracing the embedded parent ticket step by step; And S33, counting the number of tracing stages from the second sub-ticket to the source ticket when the first-stage parent ticket is traced back to the source ticket, and determining the number of tracing stages as a stage N of ticket data of the second user.
7. The agricultural product-based traceability method of claim 6, wherein the traceability series is a number of times of tracing upwards from the beginning of the second user as a historic second sub-ticket of the purchasing party to the finding of the source ticket, and each time a non-source parent ticket is found and checked, the tracing is counted as one time.

Description

Agricultural product-based tracing method, system and storage medium Technical Field The invention relates to the technical field of data application, in particular to a tracing method, a tracing system and a storage medium based on agricultural products. In particular to the field of realizing the multiple distribution and tracing of agricultural products through automatic segmentation. Background The core challenge of edible agricultural product circulation tracing is how to ensure that tracing information can truly, continuously and automatically accompany synchronous circulation and segmentation of objects in the circulation process of spanning multiple links and multiple subjects. The existing digital traceability technology mainly traces two targets around the data trusted certificate and information association to form two types of representative technical routes, but the problems of deep fusion of the business process and the data production cannot be thoroughly solved. In particular, the prior art mainly shows two modes. Firstly, an authority (such as quarantine department) system generates an initial electronic certificate as a trust anchor point, and a receiver is required to manually confirm the certificate in each subsequent circulation link through a centralized traceability platform so as to form a digitized responsibility transfer chain. Secondly, the distributed account book of the blockchain is used for storing product batch association relation and quality inspection data to ensure that information cannot be tampered, a statistical process control model is introduced, and when a certain sub-batch is abnormal in detection, the risk probability of other products in the same batch is automatically calculated to realize predictive early warning. However, the prior art has inherent drawbacks that directly limit its effective use in high frequency, multi-stage distribution scenarios of edible agricultural products. The first class of schemes suffers from the drawback that their trust transfer is highly dependent on subjective manual operation of the participating subjects, and the data generation is independent of the core physical transaction process. The system can not technically guarantee real-time synchronization and absolute reality of weighing transaction and data confirmation, and hidden danger of ticket and goods separation and post-repair and counterfeiting can not be eradicated. The second scheme has the defects that the scheme is excessively focused on the non-tamper property after the data is uplink, but the authenticity guarantee of the initial acquisition link before the data is uplink is ignored, and the depending block chain architecture and the complex prediction model are seriously different from the low-cost, easy-to-deploy and high-concurrency real requirements in the circulation field. In short, the prior art fails to construct a mandatory closed-loop mechanism for automatically generating and verifying data driven by an entity business process, which is a technical basis for realizing effective traceability supervision.
