Data management methods and devices based on indusrtial internets of things (iiot) and electronic devices

A data management device based on Industrial Internet of Things (IIoT), applied to the IIoT, wherein the IIoT includes a user platform, a service platform, a management platform, a sensor network platform, and an object platform connected in sequence, and the data management device comprises:

• a first storage module, configured to generate a data acquisition instruction and send the data acquisition instruction to a data acquisition device and a monitoring device in the object platform, and transmit and store raw data acquired by the object platform to a first general database in the sensor network platform via the sensor network platform;
• wherein the data acquisition instruction is configured to acquire the raw data in different production processes, and the data acquisition device and the monitoring device are respectively set on production equipment corresponding to the different production processes;
• a first classification module, configured to generate a first classification instruction based on a data type of the raw data and send the first classification instruction to the first general database, the first classification instruction being configured to instruct the first general database to perform a first classification on the raw data to obtain a plurality of first data sets;
• a second storage module, configured to send a first storage instruction to the first general database, the first storage instruction being configured to instruct the first general database to store the plurality of first data sets into a plurality of sub-databases configured in the sensor network platform, respectively, and transmit and store the plurality of first data sets to a second general database in the management platform via sensor network sub-platforms corresponding to the plurality of sub-databases, respectively, wherein storage capacities of different sub-databases are determined based on the different production processes;
• a second classification module, configured to generate a second classification instruction based on function types of a plurality of service sub-platforms in the service platform, the second classification instruction being configured to instruct the second general database to perform a second classification on the raw data in the plurality of first data sets to obtain a plurality of second data sets;
• a third storage module, configured to generate a second storage instruction based on a prioritization of the plurality of second data sets, the second storage instruction being configured to instruct the second general database to store the plurality of second data sets into sub-databases corresponding to different service sub-platforms, and the sub-databases being used for the service sub-platforms to call the plurality of second data sets stored therein when the service platform receives a user use request initiated by the user platform;
• a management module, configured to send, in response to existence of a data management demand, a data management instruction to the sub-databases corresponding to different service sub-platforms to realize data management, the data management including at least one of data processing order division, data verification, junk data cleaning;
• and
• an adjustment module, configured to issue, in response to completion of the junk data cleaning, an adjustment instruction to adjust a monitoring frequency of the monitoring device and/or an acquisition frequency of the data acquisition device.
