1、 毕业设计（论文）说明书 设计（论文）题目设计（论文）题目 用触摸屏监控三层电梯控制系统 系 电子信息工程系 专业班级 姓 名 学 号 指导教师 2011 年 5 月 29 日 2 摘摘 要要 本论文通过讨论电梯控制系统的选择与介绍，阐述可编程控制器（PLC）在电梯 控制中的应用，采用西门子 PLC 编程的程序控制方式，提出了三层电梯的 PLC 控制 系统总体设计方案、设计过程、组成， 列出了具体的主要硬件电路、电梯的控制梯 形图及指令表。并给出了系统组成框图和程序流程图，在分析、处理随机信号逻辑关 系的基础上，提出了 PLC 的编程方法，设计了一套完整的电梯控制系统方案。采用本 方案实现电梯
2、控制，能够解决继电器接触器触点多，故障率高、可靠性差、安装 调试周期长、维修工作量大、接线复杂等缺点。使电梯运行更加安全、方便、舒适。 触摸屏在很多方面都有应用，本文简单介绍了触摸屏的知识，并用 EB8000 软件 画出了电梯的监视画面，使电梯的运行更加的清晰安全。 关键词：三层电梯、触摸屏、PLC、自动控制 3 Abstract The present paper through the discussion elevator control system choice and the introduction, elaborated programmable controller (PLC
3、) in the elevator control application, uses Simens the PLC programming the procedure control mode, proposed three elevator PLC control system overall project designs, the design process, the composition, have listed the concrete main hardware electric circuit, the elevator control trapezoidal chart
4、and the instruction list.And has given the system composition diagram and the program flow diagram, in the analysis, in the processing random signal logic relations foundation, proposed the PLC programming method, has designed a set of complete elevator control system plan.Uses this plan realization
5、 elevator control, can solve the relay - - contact device electronic contact to be many, the failure rate high, the reliability bad, installs the debugging cycle long, the service work load big, the wiring complex and so on the shortcomings.Causes the elevator movement to be safer, to be convenient,
6、 is comfortable. The touching screen all had the application in very many aspects, this article introduced simply the touching screen knowledge, and has drawn the elevator surveillance picture with the EB8000 software, caused the elevator the movement even more clear security. Key word: Three elevators, touching screen, PLC, automatic control 4 目 录 摘 要 2 Abstract 3 目 录 4 第一章 绪论 6 1.1 课题的研究背景及意义 . 6 1
