摘　　要：控制系统采用主从站结构,主从站之间利用PROFIBUS现场总线通讯,上位机选用WinCC组态软件,设计的组态界面可以实时监控整个洗选过程以及各设备的运行状况,并实时显示和记录重要的模拟量数据。另外,对控制器编程可实现各设备单独控制和连锁启停控制。现场调试和试运行证明该系统可靠、稳定,使得选煤过程更加高效便捷,并有效提高了选煤厂的自动化程度。In this paper,control system uses master and slave structure,between which applying the PROFIBUS fieldbus communications.The PC designs configuration interface selecting WinCC configuration software,which could real-time monitor the entire washing process and the running status of each device,and real-time display and record important analog data.In addition,programming the controller can achieve controlling each device individually and controlling interlocking commitment.Site commissioning and trial operation proved that the system is reliable and stable,making the coal preparation process more efficient and convenient,and improving the automation of coal preparation plant effectively.
