前言 可编程控制器是一种应用很广泛的自动控制装置，它将传统的继电器控制技术、计算机技术和通讯技术融为一体，具有控制能力强、操作灵活方便、可靠性高、适宜长期连续工作的特点，非常适合温度控制的要求。 在工业领域，随着自动化程度的迅速提高，用户对控制系统的过程监控要求越来越高，人机界面的出现正好满足了用户这一需求。人机界面可以对控制系统进行全面监控，包括过程监测、报警提示、数据记录等功能，从而使控制系统变得操作人性化、过程可视化，在自动控制领域的作用日益显著。 本文主要介绍了基于三菱公司FX2N 系列的可编程控制器和亚控公司的组态软件组态王的某一对象温度控制系统的设计方案。编程时调用了编程软件STEP 7 -Micro WIN中自带的PID 控制模块，使得程序更为简洁，运行速度更为理想 。利 用组态软件组态王设计人机界面，实 现控制系统的实 时监控、数据的实 时采 样 与 处 理。 1 目录 第一章 概述···········································2 第二章 总方案·········································3 2.1 系统框图····································3 2.2 下位机设计··································4 2.2.1 元件选择································6 2.3 上位机设计··································8 2.3.1 监控主界面······························9 2.3.2 实时趋势曲线····························10 2.3.3 历史趋势曲线····························11 2.3.4 报警窗口································11 2.3.5 设定画面·······························12 2.3.6 变量设置·······························13 2.3.7 动画连接·······························15 第三章 总结·········································17 第四章 参考文献...
