1. An industrial Internet of Things (IoT) for correction and regulation of a defective product, comprising: a user platform, a service platform, a management platform, a sensing network platform and an object platform that interact from top to bottom, wherein
the service platform, the management platform, and the sensing network platform are all arranged in a front-sub-platform layout; the front-sub-platform layout refers to that a corresponding platform is provided with a general platform and a plurality of sub-platforms, the plurality of sub-platforms respectively store and process data of different types and different receiving objects sent by a lower platform, the general platform stores and processes the data of the plurality of sub-platforms after summary, and transmits the data of the plurality of sub-platforms to an upper platform;
the object platform is configured as a product detection device of intelligent manufacture; when the product detection device detects the defective product, the product detection device packs defective product information and a defective product parameter as the defective product data, and sends the defective product data to a corresponding sub-platform of the sensing network platform, wherein the defective product information at least includes a name, a number, and a type of the product corresponding to the defective product; and the defective product parameter at least includes a defective product parameter number and an error of the product corresponding to the defective product;
the sub-platform of the sensing network platform is configured to transform the defective product data to a data file recognized by the management platform and send the data file to the general platform of the sensing network platform;
the general platform of the sensing network platform is configured to obtain the data file, and then send, based on sub-platform information of the sensing network platform, the data file to a corresponding sub-platform of the management platform;
the sub-platform of the management platform is configured to extract the defective product parameter based on the data file, and generate, according to different parameter items, a defective product parameter table corresponding to the defective product parameter, extract the defective product information as a first description item of the defective product parameter table and enter the first description item into the defective product parameter table, and then send the defective product parameter table to the general platform of the management platform;
after obtaining the defective product parameter table, the general platform of the management platform is configured to determine a total correction cost, compare the total correction cost with the preset cost of the general platform of the management platform, the preset cost is a single-piece manufacturing cost of a product corresponding to the defective product, and perform operation based on a comparison result, including:
in response to the comparison result that the total correction cost is lower than the preset cost, determining that the defective product is correctable, the general platform of the management platform issuing a correction instruction to the corresponding sub-platform of the management platform, the general platform of the sensing network platform, the sub-platform of the sensing network platform, and the product detection device based on the first description item, the product detection device receiving the correction instruction and assigning the corresponding product to a defective product correction assembly line based on the first description item; and
in response to the comparison result that the total correction cost is higher than the preset cost, determining that the defective product is not correctable, the general platform of the management platform entering the parameter correction cost data of all parameter items and the total correction cost as a second description item into the defective product parameter table, and then sending the defective product parameter table to the corresponding sub-platform of the service platform and the general platform of the service platform; the general platform of the service platform classifying and sorting the defective product parameter table based on the first description item and the second description item and storing the defective product parameter table;
wherein to determine the total correction cost, the general platform of the management platform is further configured to:
determine a first reference vector based on a defective product vector of the defective product and a historical defective product vector library; and
determine the total correction cost of the defective product through a first prediction model based on a difference between the defective product vector of the defective product and a plurality of first reference vectors, a variance of the plurality of first reference vectors, and correction costs of the plurality of first reference vectors, wherein the first prediction model is a machine learning model, which is obtained by a training process including:
obtaining a plurality of training samples and labels, wherein the training samples includes a difference between a sample defective product vector and a plurality of sample first reference vectors, a variance of the plurality of sample first reference vectors, and correction cost of the plurality of sample first reference vectors, and the labels are the total correction cost of the sample defective product;
training an initial first prediction model based on the plurality of training samples and the labels; and
obtaining the first prediction model until a trained first prediction model meeting a preset condition.
