Real-time intelligent detection and prevention control warning method and apparatus for holographic whole-chain grain and oil product quality safety

A real-time intelligent detection and prevention control warning apparatus for holographic whole-chain grain and oil product quality safety, comprising:

• a contaminant content prediction module, configured to input, for any variety of crop planted in a target planting region, a value of a main influencing factor at each preset location in the target planting region within a current cycle into a contaminant content prediction model corresponding to the variety of crop, and obtain a content of each contaminant in the variety of crop planted at each preset location, wherein the variety of crop is configured to produce a target grain and oil product;
• one cycle comprises a production stage, a procurement stage, a storage stage, a processing stage, and a sales stage of the target grain and oil product;
• the contaminant content prediction model corresponding to the variety of crop is generated by training a convolutional neural network model based on the main influencing factor at each target sampling point in the target planting region within the current cycle and the content of the contaminant in the variety of crop planted at each target sampling point;
• and the main influencing factor is obtained by screening an environmental variable and a spatial structure variable;
• a production stage contaminant content determination module, configured to determine the content of each contaminant in the variety of crop planted at each preset location and each target sampling point as a content of each contaminant in the production stage of the target grain and oil product;
• a procurement stage contaminant content determination module, configured to determine a content of each contaminant in the variety of crop planted at each preset location and each target sampling point after harvesting as a content of each contaminant in the procurement stage of the target grain and oil product;
• a storage and processing stage contaminant content determination module, configured to store the variety of crop planted at each preset location and each target sampling point after procurement into a warehouse, determine a content of each contaminant at warehousing-in as a content of each contaminant in the storage stage of the target grain and oil product, and determine a content of each contaminant at warehousing-out as a content of each contaminant in the processing stage of the target grain and oil product;
• a sales stage contaminant content determination module, configured to process the variety of crop after warehousing-out to obtain the target grain and oil product, and determine a content of each contaminant in the target grain and oil product for sale as a content of each contaminant in the sales stage of the target grain and oil product;
• a knowledge graph construction module, configured to construct a knowledge graph corresponding to each contaminant based on a threshold range of each contaminant, the content of each contaminant in the production stage, the procurement stage, the storage stage, the processing stage, and the sales stage of the target grain and oil product within the current cycle, and entities on a grain and oil whole-process holographic traceability chain;
• and
• a prevention control warning module, configured to predict a content of each contaminant in the procurement stage, the storage stage, the processing stage, and the sales stage of the target grain and oil product within a next cycle based on the knowledge graph corresponding to each contaminant and a content of each contaminant in the production stage of the target grain and oil product within the next cycle to obtain predicted values;
• and perform prevention control warning based on the predicted values.
