NOUFERROUS METALLURGICAL EQUIPMENT

With the rapid development of the new energy vehicle industry, the market demand for nickel sulfate, a key raw material for batteries, has been continuously expanding. Nickel matte refining, as an important approach to obtaining raw materials such as nickel sulfate and cobalt sulfate, features a complex production process and has stringent requirements for system control and data management. To address this, this paper designs a production system with a four-layer architecture in combination with the production characteristics of nickel matte refining. Specifically, the L0 layer integrates field instruments, electrical equipment and PLC control systems, responsible for basic data collection and preliminary equipment control. The DCS system in the L1 layer coordinates the management and control of the production process. The L2 layer, which is a data acquisition system, takes charge of data acquisition and storage. And the MES system in the L3 layer is utilized for refined management and decision-making. This paper mainly introduces the key points of the structural design of the L0~L2 layers, defines the data types of OPC UA communication between the L1~L2 layers, ensuring efficient and accurate data interaction. Currently, this system has been successfully put into operation. It can achieve remote real-time monitoring of the production site, remote and automatic control of local equipment, automatically collect and store all production data, and stably provide data sources for the MES system. Finally, optimization strategies are also proposed for the existing structure to reduce interference, strengthen redundancy, and improve the reliability of the system connection.
