Description

Technical Field

[0001] This invention belongs to the field of agricultural product testing technology, specifically relating to an agricultural product testing management method, system, and program product. Background Technology

[0002] Currently, agricultural product quarantine and testing (such as pesticide residue testing) is a crucial link in ensuring food safety. Traditional agricultural product testing management relies heavily on manual paper records and electronic forms, which have the following significant drawbacks: 1. Poor traceability: The links between the various stages of the testing process are loose, making it difficult to quickly and accurately trace back to the specific stage and responsible person once a problem occurs.

[0003] 2. Weak tamper resistance: The detection data is easily modified or forged, and there is a lack of effective technical means to ensure the originality and authenticity of the data flow.

[0004] 3. Unclear definition of responsibilities: There is overlap or confusion of responsibilities in the sampling, sample preparation, testing, and review processes, which makes it impossible to achieve effective technical isolation and supervision, and poses internal operational risks.

[0005] Although existing technologies use QR codes to bind agricultural product information, they are mostly limited to information display and query functions. They fail to build an interlocking and tamper-proof closed-loop management logic in the generation, flow and storage of testing data, and fail to fundamentally solve the corresponding problems in the testing process. Summary of the Invention

After the verification is successful, a unique sample identification code for the corresponding batch of agricultural products is generated. The sampling data verification code is calculated using the sampling record information. The sampling label QR code is generated using the sampling data verification code and the unique sample identification code. The sampling label QR code is sent to the sampling terminal, and the sampling record information is encrypted using the unique sample identification code to obtain encrypted sampling record information. The encrypted sampling record information is then associated with the unique sample identification code and saved to the database.

[0057] This embodiment of the method deeply binds the agricultural products to be inspected with unique sample identification codes through chain-like data processing logic and a separation of responsibilities mechanism. It uses QR codes at each stage to record and transfer data at corresponding nodes, ensuring that data at every stage from sample collection to final review is automatically recorded, encrypted, verified, and clearly assigned responsibilities. This transforms the complex offline testing process into a clear online digital trajectory, achieving traceability, tamper-proofing, and reliable management of the agricultural product testing process. Through effective closed-loop management, this method enables traceability throughout the entire agricultural product testing process. Through corresponding data security and tamper-proof mechanisms, it greatly ensures the authenticity, integrity, and credibility of agricultural product quality and safety testing data (i.e., through the mandatory binding of unique sample identification codes and process sequence control, it technically ensures the separation of "collection, preparation, inspection, and review," preventing operators from exceeding their authority or falsifying data from other stages, effectively reducing internal risks). Furthermore, it improves the efficiency of agricultural product testing management and achieves standardized processing of the testing process.
