1、 中文摘要 摘摘 要要 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。 本文介绍以 FX2N 系列 PLC 为主控制器,并结合安川 616G5 变频器, 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
2、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 14 层电梯控制系统具有:定向和平层控制,门控制,内呼 信号和外召唤信号的数字控制,故障检测,楼层显示等功能。 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 的变频调速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:关键词:FX2N;变频调速;PLC;616G5 变频器; 14 层电梯; 英文摘要 Abstract In the modern society
3、 and economic activity, computer technology, automatic control technology and power electronic technology obtained a rapid development and elevator has become a city a symbol of the material civilization. Especially in high-rise buildings, the elevator is indispensable in the vertical transportation
4、 equipment. With the rapid development of the high-rise building today, elevator industry also subsequently entered the new developing period, elevator control technology has developed to FM, its logic control pressure regulating speed by PLC and replace original relay control, many of its function
5、is the traditional relay control system cant achieve. This paper mainly introduced to FX2N series, combining PLC controller 616G5 transducer, AnChuan logic control. Through the reasonable choice and design, not only increased to elevator reliability, maintainability and flexibility, and prolong the
6、life, shorten the development cycle, the elevator and raise the level of elevator control, improved the elevator running intimacy, make elevator reached the ideal control effect. This paper designed by 14 elevator control system has: directional peace layer control, door control within and outside, call summoning the signal digital control signal, fault detection, floors display function. In this elevator on the foundation of basic structure, deeply analyzes the working principle of the e
