Industrial internet of things system for smart manufacturing and control method thereof

A control method of industrial internet of things (IIoT) for smart manufacturing, which is applied to a user platform, a service platform, a management platform, a sensor network platform, and an object platform that interact in turn;

• wherein
• the user platform is configured as a terminal device, and interacts with a user;
• the service platform is configured as a first server, receives instructions from the user platform and sends the instructions to the management platform, extracts information required by the user platform from the management platform, processes the information, and sends the information to the user platform;
• the management platform is configured as a second server, controls the operation of the object platform, and receives feedback data from the object platform;
• the sensor network platform is configured as a communication network and a gateway, through which the object platform and the management platform interact;
• the object platform is configured as production line device and production line sensors that perform manufacturing;
• wherein
• the service platform, the management platform, and the sensor network platform all use centralized layouts;
• the centralized layouts mean that any platform uniformly receives data, uniformly processes data, and uniformly sends data;
• the control method comprising:
• when the terminal device modifies production line parameters based on an instruction of the user, generating, by the terminal device, a first instruction and sending the first instruction to the first server;
• processing the first instruction to generate a second instruction and sending the second instruction to the second server by the first server, the second instruction being used to be identified by the second server;
• modifying work order parameters stored in the second server based on the second instruction, and generating a third instruction based on the modified work order parameters by the second server;
• and
• when the second server sends the third instruction to the object platform through the sensor network platform, executing manufacturing and collecting production line data based on the third instruction by the object platform;
• the method further comprising:
• sending, by the object platform, the collected production line data to the second server through the sensor network platform to form a production line database;
• extracting corresponding data from the production line database and sending the data to the terminal device according to a preset rule or a request of the terminal device by the first server;
• and
• displaying the received data to the user by the terminal device;
• and
• the method further comprising:
• traversing the production line database in a production process of the object platform, and extracting data of each production link during the production of each product from the production line database as production cycle data of the each product by the second server;
• establishing a mapping relationship between the production cycle data of the each product and a qualification condition of the each product to form sample data by the second server;
• using, by the second server, a support vector machine to classify the sample data to generate a binary classifier;
• input data of the binary classifier is the production cycle data, and output data of the binary classifier is whether the product is qualified;
• and
• when a production cycle of a new product is completed, inputting production cycle data of the new product into the binary classifier, and determining whether the new product is qualified based on an output result of the binary classifier by the second server.
