At present, there are some problems in aluminum industry production, such as complex business logic of new and old systems, difficulties in data exchange, data dispersion and redundancy, separation of business processes, data privatization, fragmentation of application departments, poor data continuity, low quality of supervision, single result of data analysis, poor readability and so on. Industrial data is not fully and effectively collected, fused and utilized, which leads to the emergence of information isolated island. According to the production process, process characteristics and reaction mechanism of aluminum smelting enterprises, combined with the existing basic conditions such as production control network, office information network, production automation control system and management application system, using mobile Internet, cloud computing, industrial Internet of things, industrial big data and other technologies, to carry out industrial data collection, data exchange, data analysis, data management and big data services, The development of aluminum industry data fusion platform, expert reasoning system based on industrial data, advanced process control system, remote operation and maintenance diagnosis system and other application services is an important part of intelligent factory construction, as well as an important way of industrial data empowerment and value discovery, which can create economic benefits for enterprises, improve their core competitiveness and maintain their leading position in the industry.
Recently, aiming at the problem of insufficient and effective collection, fusion and utilization of industrial data, the team of Guiyang Aluminum and magnesium Design and Research Institute (hereinafter referred to as Guiyang Aluminum magnesium Institute) has developed a set of one-stop management and control data platform through big data and other technologies, which can realize industrial data standardization and multi-dimensional fusion, including data collection, processing, storage, fusion, exchange, governance and service modules. The platform can realize the data integration of management information system and production process system, has the ability of comprehensive data search and data warehouse analysis, the ability of integrating structured and unstructured data, and the data storage capacity of PB level. The platform can realize multiple data sources within the enterprise, carry out automatic data processing and verification such as unified data caliber and business rule cleaning, and on this basis, realize multi-source heterogeneous data access and aggregation, through automated centralized management and data governance, provide data empowerment for a variety of business scenarios to ensure the effective use of the aggregated data, so as to fully tap the value of the data and promote data value-added. Help industry users to achieve digital transformation.
This technology can be applied to the industrial data fusion of electrolytic aluminum, alumina and carbon anode production enterprises, the development of industrial data analysis, decision-making, management and control integrated system in the production process, as well as economic benefit analysis.
The platform has a powerful connection function, which can connect the data source and destination, and load the data of different systems into the data warehouse after extraction, cleaning and transformation. thus, the scattered, disorderly and non-uniform data in the enterprise are integrated together to provide an analytical basis for enterprise decision-making. Relying on the big data fusion platform of the aluminum industry, industry users can carry out predictive maintenance of production equipment, production process optimization, personnel operation optimization and man-machine collaborative optimization, so as to improve quality and efficiency, intelligent production, and help to realize the transformation, upgrading and high-quality development of the industry.
At present, the data platform has been demonstrated and applied in an electrolytic aluminum enterprise, and the operation effect is good. At the same time, this technology is also gradually popularized and implemented in alumina and anode carbon enterprises.
