OPC技术和工业以太网在炭素阳极生产中的研究与应用

Research and Application of OPC Technology and Industrial Ethernet in Carbon Anode Production

以电解铝炭素生阳极生产系统为背景,综合运用OPC技术和工业以太网,对如DCS、FCS、PLC和智能仪表等异构网络在网络级与接口级上的同构化集成问题上进行研究。通过PLC硬件与OPCServer组态,实现监控中心与下位PLC系统的通信;整个网络采用分散控制、集中管理的布置方式,最大程度满足工艺生产和用户需求。该系统支持开放和通用的以太网、TCP/IP和相关的技术,使自动化系统易于与MES和ERP系统无缝连接。经过实际测试和运行,网络系统构成灵活、数据读取实时性好,可靠性强,便于系统升级和扩展。

In this paper, the electrolytic aluminum and carbon green anode production system is the background, comprehensive OPC technology and industrial Ethernet, it researches the isomorphism integrated problem on the network level and interfaces the label of heterogeneous network such as DCS, FCS, PLC and smart instrument. Through the PLC hardware and OPC Server configuration to achieve the monitoring center and the next PLC system communication, we use the entire network as decentralized control and centralized management arrangement, also the maximum extent to meet the production process and user needs. The system supports an open and versatile Eth-ernet, TCP/IP and related technology, the automation system easily achieve seamless connection with MES and ERP systems.
