| 摘 要： | 针对造纸机纸幅张力的控制要求,基于西门子PCS7平台,以s7-400H PLC为控制中心,通过OPC技术,设计了一种张力调节控制系统。该系统可以利用EXCEL的线性规划寻优求解功能,对WinCC里的张力设定值进行实时优化调节。介绍了系统的组成及工作原理,论述了系统各功能的硬件、软件设计,针对系统组成方式,给出了主要程序的控制流程。实际运行表明,系统可进行良好的张力控制,具有易于实现、自我调节能力强等优点,较好地减少了纸幅断头及褶皱的发生。

| Abstract: | According to paper tension control requirements of paper machine, based on the Siemens PCS7 platform, and using S7-400H PLC as the control center, a tension control system was designed through the OPC technology. The tension set value in WinCC was regulated optimatically using linear programming function of Excel. The main composition and working principle of the system was introduced. The design of system's hardware and software for each function was discussed. The control flow of main program was given for system components. The actual operation showed that the paper tension control system can realize optimal tension control; it has the advantage of easy realization and strong self-regulation ability; it obviously reduces the occurrence of paper breaks and folds. |
