1、 1 摘 要 在现代社会和经济活动中，电梯已经成为城市物质文明的一种标志。 特别是在高层建筑中，电梯是不可缺少的垂直运输设备。电梯控制技术已 经发展到了调频调压调速，其逻辑控制也由 PLC 代替原来的继电器控制， 其许多功能是传统的继电器控制系统无法实现的。 本设计针对我国电梯业的现状， 将可编程序控制器(PLC)应用于八层电 梯进行逻辑控制，通过合理的选择和设计，不但提高了电梯可靠性、可维 护性以及灵活性，同时延长了使用寿命，缩短了电梯的开发周期，并提高 了电梯的控制水平，改善了电梯运行的舒适感，使电梯达到了较为理想的 控制效果。该电梯控制系统具有指层、厅召唤、选层选向、手动和自动等 功能，

2、具有集选控制的特点。 在介绍电梯基本结构的基础上，深入分析了电梯的工作原理，阐述了 PLC 的优点及特点，重点分析了电梯的硬件设计和软件设计，研究并提出 了基于 PLC 电梯控制系统设计的实现方案，最后对本论文的研究内容进行 了总结与展望。 关键词 电梯 变频器 PLC 控制 变频调速 2 Title: Eight-storey Elevator PLC Control Abstract: In the modern social and economic activities, computer technology, automatic control technology and pow

3、er electronic technology has been rapid development. Especially in the high-rise building, the elevator is not a lack of vertical transportation equipment. elevator control technology has been developed to the FM speed regulator, the logic control by the PLC to replace the original relay control, ma

4、ny of its functions traditional relay control system can not be achieved. The design for the status quo of Chinas elevator industry will be a programmable logic controller (PLC) used for four-storey elevator control logic, through the rational selection and design, not only to improve the reliabilit

5、y of the elevator, maintainability, and flexibility, while extending the of life and shorten the development cycle of the elevator and the elevator control to raise the level of the elevator operation to improve the comfort, so that the lift to reach a more satisfactory control effect. In this paper

6、, the design of the elevator by the elevator when compared with the traditional, in the run with good comfort, in life can save energy, and achieved good economic and social benefits to achieve the desired purpose. The elevator control system has a mean layer, the Office of calls to the layer selected, manual and automatic 3 functions with a set of features to control the election. In introducing the basic structure of the lift on the basis of the depth analysis of the working principle of
