A precise perception and intelligent decision-making method and mes system for aluminum electrolytic production

Abstract

The present invention discloses an aluminum electrolytic MES system based on an accurate perception and an intelligent decision. The system comprises an electrolytic tank online detection device (1) for detecting aluminum electrolytic real-time production data, an online detection data collection device (10) for collecting real-time production data, an intelligent mobile terminal (2) for obtaining the position information of an operator, a plant wireless or wired network (3), a production billboard (4) for information display, an information integration platform (5), a production management system (6) based on production process real-time data, an aluminum electrolytic process energy management system (7), an expert operation system (8) based on electrolytic tank (11) real-time production data, and an intelligent controller (9) for production control. According to the system, the degree of precision and the automation level of the aluminum electrolytic production management and control can be improved, the management efficiency is improved, and the influence on aluminum electrolytic production brought by personnel technology and management level differences can be reduced.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis production management and control systems, in particular to an aluminum electrolysis MES system based on accurate perception and intelligent decision-making. Background technique [0002] For a long time, the problems of energy saving, consumption reduction and emission reduction have been plaguing electrolytic aluminum production enterprises. With the increasing demand for energy saving and high-efficiency production in the aluminum electrolysis industry, the world's aluminum industry has made great efforts to control technology and management technology in aluminum electrolysis production. applications are of great concern. [0003] In the production process of aluminum electrolysis, the scientific integration of dispatching human, financial and material resources and improving the control level of electrolytic cells are the key to improving current efficiency and reducing energy c...

Problems solved by technology

[0007] Analyzing the MES technology and products at home and abroad, we can see that some of the existing MES products come from the original bottom-level automation suppliers, and some of them come from suppliers of enterprise resource management and supply chain management, all of which have strong industry pertinence. The versatility is not strong, for example: S-MES is mainly used in the petrochemical industry. For the complex electrochemical process of aluminum electrolysis, if these products are applied to the aluminum electrolysis production industry, it is difficult to solve many uncertain factors, difficult on-line detection, and complicated management and other issues, it is bound to carry out larger-scale secondary customization development work, so related products do not have the promotion value in the aluminum industry

For this reason, in the electrolytic aluminum industry, the world's advanced aluminum industrial enterprises such as French Alcoa and Alcoa have been exploring MES customized solutions, and have conducted a lot of research and practice in production cost control and workshop operation management. The integration with the DCS layer has achieved certain results, but there are still many deficiencies in the evaluation and management of production quality, tank condition monitoring, etc., and no standardized products and solutions have been formed. There are still many management and technical issues that need further improvement. explore and refine
