AI Technical Summary

Technical Problem

In multi-production-line steel enterprises, traditional centralized intelligent control methods are difficult to adapt to the differences in operating conditions of each production line, resulting in poor model generalization ability, decreased control accuracy, and data privacy risks and transmission pressure. Simple weighted global control strategies may exhibit negative migration, affecting steel slag treatment efficiency and environmental pollution.

Method used

A distributed collaborative control system for steel slag processing across production lines is adopted. Through the collaborative work of the underlying data acquisition terminal, industrial edge controller and industrial cloud platform, the control strategy fusion mechanism is dynamically adjusted. The fusion weight is calculated based on the feature vector of steel slag working condition, a global control strategy is generated and the control commands are updated in real time.

Benefits of technology

It enables the sharing and updating of control strategies across production lines without transmitting plaintext production data, improving control accuracy and stability, adapting to dynamic changes in each production line, ensuring the real-time nature of control commands and closed-loop execution, and avoiding negative migration.

Abstract

The application relates to the technical field of industrial control and discloses a cross-line steel slag treatment distributed collaborative control system and method. Steel slag physicochemical property data and equipment working condition data are collected at a bottom-layer data collection terminal of each independent production line, a working condition-control correlation sample set is constructed at an industrial edge controller to train a local control strategy model, and control strategy parameter adjustment amounts are generated and uploaded to an industrial cloud platform. The industrial cloud platform determines a distribution difference degree based on steel slag working condition feature vectors of each production line, each industrial edge controller generates bottom-layer control messages based on global control strategy parameters, outputs feedforward instructions, drives water regulating valves and frequency-regulating fans to perform regulation, and collects feedback data for subsequent model updating. The application realizes the sharing and updating of cross-line control strategies by uploading only the control strategy parameter adjustment amounts to the industrial cloud platform for control strategy fusion based on the working condition distribution difference degree.
