摘要
根据工业恒压供水的要求,采用PLC与变频调速技术对供水泵组进行控制,并在控制系统中引进了软硬件双重滤波技术和数字PID在线控制技术。介绍了系统的硬件构成、软件设计、工作原理、运行方式、参数整定等。长时间的运行表明系统的稳定性和安全性很好。
The paper studies the application of PLCs,frequency variable and speed regulating (VF SR) technology to the control of water supply pumps.It introduces hardware and software filtering and digital PID on-line control to a control system whose hardware configuration,software design,working principles,operation modes and parameter tuning are proposed in this paper too.Long-time operations have proved that the system is of high stability and safety.
