摘要
根据某公司硅铁自动配料系统的要求,在分析配料工艺过程和具体控制要求的基础上,系统采用工控机和下位机可编程逻辑控制器(PLC)相结合的控制方式。同时采用迭代控制算法和冗余补偿实现配料误差的精确控制并在PLC程序中得以实现。系统采用以太网转换器ETHi BUS实现PLC与Win CC间实时数据的快速交换。最后,设计了系统人机交互界面。该系统实现了对整个配料过程的监控以及数据管理,并对配料误差进行冗余补偿,进而提高了系统的配料精度。现场情况表明该系统运行可靠,基本实现了全自动化,具有较高的推广应用价值。
Based on the requirement industrial silicon automatic batching system,it analyzes the batching process and the specific control requirements,combines both the computer and PLC to control the system. It designs the iterative control algorithm and a blueprint of the interface,proposes redundancy compensation and realizes to control the batching error in the PLC programmer. It applies Ethernet switches ETH-BUS to exchange the realtime data between PLC and WINCC. The system successfully manages the data and monitors the whole process.The actual operation shows that the system is very stable,basically achieves full automation and has the value to spread.
