文档介绍：中文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。这里主要是对电梯牵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。其中对牵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 牵引机电动机减速器联轴器制动器 Abstract This design istake FX2n asthe core elevator control system position and the software design, uses the PLC integrated circuit tocontrol the sedan box topromote the electrical machinery, tostop with, the reverse. Here mainly iscarries onthe design, putation tothe elevator tractor parameter, (including electric motor, reduction gear, axis, bearing, shaft coupling, brake) aswell asthe craft arrangement and the correlation graph plan, moreover tothe PLC integrated circuit control system design, mainly isthe PLC integrated circuit control circuit diagram, the program flow diagram aswell asthe PLC integrated circuit programming. The most important ofthis design ischanged huge parts ofcontents. The new version increases plenty ofnew technical contents and new calculation method. PLC integrated circuit control system design .Besides afew parts are changed according tothe Chinse lift situations, this revised version pliant Now the elevator all uses the method oftraditional the relay group control, because ofmany relay have been used, control the volume huge, the cost ofcontrol system ishigh, most ofthe multitudinous relay movement have the big noise, the pollution environment. Uses the PLC integrated circuit coordination connection tocarry onthe control, may e the traditional black-white control logic puter program control logic, removes all uses inthe logical control intermediate relay, causes the cost ofthe elevator system and the noise reduces greatly, controls the the volume also tobepossible toreduce gre
