1、 1 摘 要 自动控制升降旗在原 来传统的手动控 制的基础上进 行革新的一 种最新型的产物.随着可编程控制器在 我国的发展,对升降旗的控制 要求也 越来 越高,使得 越来 越多的 控制 部分 需要 可编 程控制 器来 实 现. 本 文 结合 任 务 设 计 书 的 要求 ,以 自 动控 制 为 研 究 对 象,采 用 了 S7-300 系列 PLC 作为自动控制的控制器.对自动控制升降旗系统的总 体功能进行了分析,阐述了可编程控制 器的组成和工作原理.提出了 自动控制的硬件的各组成模块及详细的硬件模块设计方案,并对控制 方式进行了设计和程序的编程.本设计 改善了升降旗的控制品 质,并 真正地达
2、到了实时控制的要求. 关键词:PLC 升降旗 自动控制 2 Abstract Automatic control down the flag in the original traditional manual control innovation on the basis of a new type of product. With the development of PLC in China, to lift the flag of the control requirements have become more sophisticated , making more control
3、of the programmable controller to realize some of the needs. In this paper, the design of the receipt of the task to automatically control for the study, using the S7-300 Series PLC controller for automatic control. In this paper, the design of the receipt of the task to automatically control for th
4、e study, using the S7-300 Series PLC controller for automatic control. The automatic control system of lifting the overall function of the flag were discussed, elaborated on the composition of the programmable controller and work. proposed automatic control of various components of hardware modules and the detailed design of hardware modules, and control procedures for the design and programming. This design improves the quality control of the flag down and really achieve the real-time control
