1、www.88doc88.com摘要本次设计是以三菱FX2n为核心的电梯控制系统的硬件组成及软件设计,采用PLC来控制轿箱提升电机的起、停和正、反转。这里主要是对电梯曳引机的参数进行设计、计算、(包括电动机、减速器、轴、轴承、联轴器、制动器)以及工艺的编排和相关图形的绘制,另外对PLC控制系统的设计,主要是PLC控制电路图、程序流程图以及PLC编程。其中对曳引机的设计重点是减速器的选择和箱体零件的设计和加工。减速器选择的是蜗杆减速器,轴承是调心滚子轴承,联轴器选择的是弹性柱销联轴器。PLC控制程序设计是考
2、虑到电梯的上升和下降逻辑,以及楼层显示,运作时的加速和减速。现在电梯都采用传统的继电器群的控制方法,由于所用的继电器较多,控制柜体积庞大,控制系统成本高,而且众多继电器的动作会产生较大的噪音,污染环境。采用PLC配合接口进行控制,可将传统的继电器控制逻辑变为计算机程序控制逻辑,去掉所有用于逻辑控制的中间继电器,使电梯系统的成本和噪音大大降低,控制柜的体积也可大大缩小。关键词:PLC;曳引机;电动机;减速器;联轴器;制动器www.yanziedu.comwww.88doc88.comAbstractThi
