摘　　要：针对过程控制实验装置中存在的一些缺陷,设计了基于SMPT-1000仿真设备的蒸发器实验平台的控制系统,模拟了实际生产过程中的蒸发器装置的工艺流程。利用PCS7集成开发环境和西门子PLC400控制器,完成了基于PROFIBUS总线的硬件组态。利用CFC功能,实现了蒸发器的温度、液位和流量的PID控制及其控制器参数整定。通过对实验结果的分析,控制方案具有较好的实用性和可靠性,设计的蒸发器实验系统可以模拟实际工业现场的实际装置,是一个较为理想的实验教学平台。A control system of evaporator experimental platform is designed based on SMPT-1000 simulation device. It can overcome some disadvantages of experimental devices used for the process control,and also achieves the simulation of technological process on practical production for the evaporator device. By the integrated development environment PCS7 and the controller Siemens PLC400,the hardware configuration is established. The PID control schemes for the temperature,liquid,level and flow rates of the evaporator and the tuning methods of the PID controllers are achieved by using the CFC function of PCS7. The control scheme owns good practicability and reliability by the analysis of the experimental results. The designed evaporator experimental system can simulate the practical device in the industrial field,and is an ideal teaching platform.
