为了提高轧钢厂老式棒材连扎线的使用效率和可靠性,提出了一种基于PAC系统平台的 控制系统。该系统充分发挥工业PAC系统高集成性、低成本、高可靠性等优势,利用机械上多种可以测取的信号,实现了对连扎线的自动控制、在线监测和故障诊断。详细讨论了系统的硬件构成和软件结构,介绍了监测控制模块和故障诊断模块的组成结构。 关键词 :棒材连扎线; 可编程自动化控制器; 监测控制; 故障诊断 Abstract : In order to improve the efficiency and reliability of the continuous rod rolling line in rolling mill, a control system based on PAC platform is put forward. This system not only takes full advantages of the industrial PAC, but also uses a variety of mechanical signal to realize the auto-control, on-line monitoring and fault diagnosis of the rolling line. Then detailed discussion on the hardware and software of the system is presented, especially on the architectual of it.
