| 摘 要： | 讨论了基于西门子公司PCS7集散控制系统应用于蒸发器对象的控制系统设计。在对蒸发器工艺流程和动态特性分析的基础上,给出了基于PCS7的蒸发器控制系统设计方案,并针对浓缩液浓度不可测的情况设计了推理控制策略;用SCL、CFC等语言实现了过程控制等用户控制程序;用WinCC实现了系统人机交互和系统监控。通过系统调试运行,验证了控制系统设计方案的先进性、可靠性、可行性。

Design of Evaporator ControI System Based on PCS7 |
| |
| Abstract: | This paper discusses a control system of evaporator based on SIMATIC PCS7.Based on the analysis for the processing and the dynamic characteristics of evaporator,a solution of control system based on PCS7 is given,and for the unpredictable situation of the concentration,an inference control strategy is designed.User control programs such as basic process control are implemented by using software SCL,CFC.The HMI and system monitoring are realized with WinCC.Through debugging and running,the advanced,reliability and feasibility of the control system are verified. |
