基于OPC技术的过程控制仿真实验设计

摘要

针对现有的过程控制实物实验装置在教学使用过程中存在的问题，设计了基于O PC通信技术的过程控制仿真实验。该仿真实验利用 KingACT 软件实现典型工艺过程的闭环控制仿真，并通过OPC技术与K ing V iew组态软件进行实时通信，实现了对典型工艺过程的监控。以双容水箱液位控制工艺过程为例，说明了设计仿真实验的具体过程。应用结果表明：该仿真实验便于学生进行二次开发和开展创新研究。%Aiming at the problem of the process control experimental devices during the experimental teaching , the process control simulation experiment based on OPC technique is designed .In this simulation experiment , the closed‐loop control simulation of the typical productive process is realized by the KingACT software ,then it communicates with the KingView configuration software through the OPC technique ,and the monitoring to the productive process is finished .The application effect shows that it is able to help the students finish the secondary development and innovation research .
