三菱PLC变频调速电梯的PLC控制系统
毕业设计论文
摘要
在现代社会和经济活动中计算机技术自动控制技术和电力电子技术得到了迅速的发展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随着高层建筑飞速发展的今天电梯行业也随之进入了新的发展时期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 应用于四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本文所设计的电梯与传统的电梯相比在运行上具有良好的舒适感在生活中可以节约电能取得了良好的经济效益和社会效益达到了理想的目的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
Abstract
In the modern social and economic puter technology automatic control technology and power electronic technology has been rapid development the lift has e a symbol of urban material Especially in the high-rise building the elevator is not a lack of vertical transportation equipment With the rapid development of high-rise buildings of today the lift industry also has entered a new period of development elevator control technology has been developed to the FM speed regulator the logic control by the PLC to replace the original relay control many 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 reliability 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 fort so that the lift to reach a more satisfactory control effect In this paper the design of the elevator by the elevator pared with the traditional in the run with fort 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 a
