Method for retrieving target data based on industrial internet of things (iot)

Industrial Internet of Things (IoT) for retrieving target data, comprising:

• a terminal device, a first server, a second server, a gateway, production line devices, and device data collectors, wherein the terminal device is configured as a use platform, the first server is configured as a service platform, the second server is configured as a management platform, the gateway is configured as a sensor network platform, and the production line devices and the device data collectors are configured as an object platform, which are interacted sequentially, wherein
• the user platform interacts with a user;
• the service platform is configured to:
• receive an instruction of the user platform and send the instruction to the management platform, and
• extract information required for the user platform from the management platform, process the information, and send the information to the user platform;
• the management platform is configured to control an operation of the object platform, and receive feedback data of the object platform;
• the sensor network platform is configured for interaction between the object platform and the management platform;
• the production line devices and the device data collectors of the object platform are divided into a plurality of target objects in different process sequences according to processes of manufacturing an assembly line product, and a device data collector of a same target object is used to collect real-time data of a production line device of a corresponding process;
• each sub platform of the sensor network platform corresponds to target object data of each of different process sequences, the target object data includes threshold data of a production line device stored in each sub platform database and real-time data collected by a device data collector, each sub platform database is configured in the gateway;
• and
• when the real-time data of the production line device is greater than the threshold data, a sub platform corresponding to the production line device retrieves the target object data in a corresponding sub platform database, packages the target object data into packaged data and transmits the packaged data to a general platform of the sensor network platform;
• wherein
• the threshold data of the production line device includes a fixed parameter value of a maximum threshold allowed by a corresponding production line device during product manufacturing, the real-time data is a real-time parameter value collected by the device data collector of a corresponding production line device according to a predetermined time, and the real-time parameter value and the fixed parameter value belong to a same parameter type.
