1、PLC 在电梯控制中的应用研究在电梯控制中的应用研究 摘 要 电梯是垂直方向的运输设备，是高层建筑中不可缺少的交通运输设备。它靠电力， 拖动一个可以载人或物的轿厢，在建筑的井道内导轨上做垂直升降运动。 随着现 代城市的发展，高层建筑日益增多，电梯成为人们日常生活必不可少的代步工具。 电梯性能的好坏对人们生活的影响越来越显著， 因此必须努力提高电梯系统的性能， 保证电梯的运行既高效节能又安全可靠。采用 PLC 对电梯信号系统进行控制，开 发出了完整的电梯控制软件，提高了电梯的控制水平，并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。而控制电梯运行的 PLC 系统也要求越来越高， 要求
2、达到电梯运行的“稳、准、快”的运行目的。该系统主要由 PLC、逻辑控制电 路组成。其中包括交流异步电动机、继电器、接触器、行程开关、按钮、发光指示 器和变频器组成为一体的控制系统。 关键词：电梯、PLC、梯形图 The application of PLC in the elevator control Abstract An elevator is vertical transport equipment, high-rise building is the indispensable transportation equipment.
