摘要
蒸养工序的智能控制系统采用Wincc组态软件、西门子S7-200smart PLC和OPC(Object Linking and Embedding for Process Control,用于过程控制的OLE)通信技术,构成了集检测、记录、报警、控制等功能于一体的闭环控制系统。重点介绍了控制系统组织架构、滞后系统的控制算法、C语言在Wincc组态技术中的应用以及OPC通信技术。经调试运行,系统的可靠性和测控精度都达到设计要求。
The steaming process intelligent control system adopts wincc＇ s configuration software, the siemens s7-200smart PLC and the OPC（Object Linking and Embedding for Process Control） Communication Technique. The closed Loop Control System has all the functions of Detection, recording, alarm and control.This paper emphatically introduces the control system＇ s framework, the control algorithm for control systems with large delay, the application of C language in wincc configuration technology and the OPC communication technology. Atter debugged, system work reliability and precision can meet actual demand.
