pasting a traceability two-dimensional code outside the package of the intermediate product; the tracing two-dimensional code displays basic information of the intermediate product after being scanned by a two-dimensional code scanning instrument; the basic information of the intermediate product comprises the manufacturer, weight, purchaser information, producer information, two-dimension code numbers of the used basic raw materials and two-dimension code numbers of the intermediate product;
the finished product label module marks a tracing label on a food finished product in the following way:
after the finished product is produced, pasting a traceability two-dimensional code outside the package of the finished product; the traceable two-dimensional code displays basic information of a finished product after being scanned by a two-dimensional code scanning instrument; the basic information of the finished product comprises the manufacturer, the weight, the buyer information, the producer information, the two-dimension code number of the used intermediate product and the two-dimension code number of the finished product;
the logistics label module is used for marking a tracing label for each logistics transportation, and the logistics label module comprises the following steps:
each logistics enterprise generates a logistics traceability two-dimensional code for each round of logistics transportation; the logistics tracing two-dimensional code displays basic information of the current logistics; the basic information of the logistics comprises a logistics number of the current logistics, a logistics start point and a logistics end point and a two-dimensional code number set of the transported goods;
the production monitoring module judges whether the production is abnormal or not in the following way:
the production monitoring module tracks the purchase quantity and the stock quantity of each food intermediate product manufacturer and finished product manufacturer to the basic raw materials and intermediate products, and the corresponding production quantity of the intermediate products and the production quantity of the finished products in real time; calculating the production quantity of the intermediate product and the quantity of the basic raw materials and the intermediate products which are consumed by the production quantity of the finished product according to the material proportion of the product; if the comparison between the quantity to be consumed and the inventory consumption quantity is inconsistent, the abnormal production is indicated; the production monitoring module sends production abnormality information to related supervision departments;
the product traceability module is mainly used for tracing the processing process of the product by scanning the two-dimensional code on the finished product package after the consumer purchases the finished product;
the product traceability module performs traceability on the processing process of the product, and comprises the following steps:
step S1: the consumer scans the two-dimension code of the finished product package to obtain the basic information of the finished product;
step S2: the consumer searches a logistics two-dimensional code number corresponding to the two-dimensional code number of the intermediate product from the product tracing module according to the two-dimensional code number of the intermediate product in the basic information of the finished product; judging whether the logistics terminal displayed by the logistics two-dimensional code is consistent with the production place of the finished product, if not, indicating that the production of the finished product of the food is abnormal; otherwise, go to step S3;
step S3: the consumer searches out the two-dimension code number of the corresponding basic raw material from the product traceability module according to the two-dimension code number of the intermediate product; searching out a corresponding logistics two-dimensional code number according to the basic raw material two-dimensional code; judging whether the logistics terminal displayed by the logistics two-dimension code is consistent with the production address of the intermediate product; if the food intermediate products are inconsistent, the abnormal production of the food intermediate products is indicated.
2. The Internet of things-based food safety control and tracing method is characterized by comprising the following steps of:
step one: the product information collection module collects production basic information of each food manufacturer in advance; the production basic information collected by the product information collection module comprises the product name, the product model and the material required by the production of the product of each food manufacturer, and the proportion of each material in the unit product;
step two: the raw material label module marks a raw material traceability label on a basic raw material of the food; the raw material traceability tag is used for displaying basic information of food material basic raw materials; the basic information of the basic raw materials comprises the production place, weight, buyer information, cultivation personnel information and raw material two-dimensional code numbers of the basic raw materials;
step three: the intermediate product label module marks an intermediate product traceability label on an intermediate product of the food; the intermediate product traceability tag is used for displaying basic information of the intermediate product; the intermediate product basic information comprises an intermediate product manufacturer, weight, purchaser information, producer information, a two-dimension code number of a used basic raw material and an intermediate product two-dimension code number;
step four: the finished product label module marks a finished product traceability label on a finished product of the food; the finished product traceability tag is used for displaying basic information of a finished product; the basic information of the finished product comprises the manufacturer, the weight, the buyer information, the producer information, the two-dimension code number of the used intermediate product and the two-dimension code number of the finished product;
step five: the logistics label module marks a tracing label for each logistics transportation; the tracing label is used for displaying basic information of the current logistics; the basic information of the logistics comprises a logistics number of the current logistics, a logistics start point and a logistics end point and a two-dimensional code number set of the transported goods;
step six: the production monitoring module collects the relations of the goods inlet amount, the goods outlet amount, the stock amount and the product raw material ratio of the food manufacturer in real time and is used for judging whether the production is abnormal or not;
step seven: after purchasing the finished product, a consumer traces the processing process of the product by scanning the two-dimensional code on the package of the finished product; the tracing mode comprises the steps of comparing whether the address information of the logistics tracing label with the address information of the intermediate product tracing label and the address information of the raw material tracing label are different, and analyzing the finished product tracing label, the intermediate product tracing label and the raw material tracing label layer by layer to obtain the production and cultivation processes of the finished product, the intermediate product and the basic raw material.
