摘　　要：陶瓷辊道窑烧成段温度控制作为影响陶瓷质量的重要因素存在时间常数大、放大系数小的情况,简单的单回路闭环控制效果不佳,笔者提出了基于S7-200 SMART PLC的烧成段串级控制系统的设计思路,并完成了硬件系统的设计、PLC程序设计和MCGS触摸屏的设计。The firing section’s temperature control in a ceramic kiln affects the ceramic quality much and features a large time constant and a small amplification factor and the simple single-loop closed-loop control often has poor control effect. Having a S7-200 SMART PLC-based cascade control system designed for the burning section was proposed and its hardware system, PLC program and touch screen were designed.
