摘　　要：伴随新能源汽车产业的迅猛发展,三元动力电池关键原料硫酸镍的市场需求呈持续扩张态势。高冰镍精炼作为获取硫酸镍及硫酸钴等原料的重要途径,其生产流程复杂且对系统控制与数据管理要求严苛。为此,本文结合高冰镍精炼生产特性,设计了四层架构生产系统:L0层集成现场仪表、电气设备及PLC控制系统,负责基础数据采集与设备初步控制;L1层DCS系统,统筹生产流程管控;L2层数据采集系统,负责数据汇总及存储;L3层MES系统,用于精细化管理决策。着重介绍了L0~L2层结构设计要点,定义了L1~L2层间OPC UA通讯数据类型,确保数据高效精准交互。目前该系统已成功运行,能实现生产现场远程实时监测、就地设备远程及自动化控制,自动采集存储全部生产数据,为MES系统稳定供源。最后针对现有结构提出优化策略,削减干扰、强化冗余,提升系统连接可靠性。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 decisionmaking.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.
