Industrial internet of things system for managing production task and control method thereof

A control method of Industrial Internet of Things for managing a production task, wherein the control method is executed by a management platform of an Industrial Internet of Things system for managing the production task, the Industrial Internet of Things system further comprises a user platform, a service platform, and a sensor network platform that are interacted sequentially, the control method comprising:

• receiving, by the service platform, a modification instruction of a user from the user platform and sending the modification instruction to the management platform, wherein the modification instruction includes an industrial production task modification instruction input by the user;
• obtaining, by the management platform, raw material data through the sensor network platform, obtaining reference material data from a database, wherein the database includes a plurality of groups of reference data, each group of reference data includes the reference material data and reference process parameters, and the reference material data correspond to the reference process parameters one by one;
• matching, by the management platform, the raw material data with the reference material data, and determining target reference material data whose matching relationship satisfies a preset condition, and
• taking, by the management platform, reference process parameters corresponding to the target reference material data as first candidate process parameters;
• performing, by the management platform, at least one iteration on the first candidate process parameters based on a preset algorithm to obtain second candidate process parameters;
• wherein the at least one iteration comprises:
• updating change rates to be updated to obtain updated change rates;
• updating process parameters to be updated based on the updated change rates to obtain updated process parameters;
• taking the updated process parameters as the process parameters to be updated in a next round and taking the updated change rates as change rates to be updated in the next round until a first preset condition is satisfied, and the iteration ends, wherein
• the process parameters to be updated in a first round are the first candidate process parameters, and the change rates to be updated in the first round are preset values;
• and
• the second candidate process parameters are determined based on the updated process parameters;
• determining, by the management platform, target process parameters of a process equipment on an industrial production line based on cost values corresponding to the second candidate process parameters;
• determining, by the management platform, a modification plan based on the target process parameters and sending the modification plan to the sensor network platform;
• and
• determining, by the sensor network platform, an execution instruction based on the modification plan and distribute the execution instruction, and controlling the process equipment on the production line to produce according to the target process parameters in the modification plan.
