1、 2 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
2、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 3 Abstract This design is take FX2n as the core elevator control system hardware composition and the software design
3、, uses the PLC integrated circuit to control the sedan box to promote the electrical machinery, to stop with, the reverse. Here mainly is carries on the design, the computation to the elevator tractor parameter, (including electric motor, reduction gear, axis, bearing, shaft coupling, brake) as well
4、 as the craft arrangement and the correlation graph plan, moreover to the PLC integrated circuit control system design, mainly is the PLC integrated circuit control circuit diagram, the program flow diagram as well as the PLC integrated circuit programming. The most important of this design is chang
5、ed huge parts of contents. The new version increases plenty of new technical contents and new calculation method.PLC integrated circuit control system design. Besides a few parts are changed according to the Chinse lift situations, this revised version is basically compliant Now the elevator all use
6、s the method of traditional the relay group control, because of many relay have been used, control the cabinet volume huge, the cost of control system is high, most of the multitudinous relay movement have the big noise, the pollution environment. Uses the PLC integrated circuit coordination connection to carry on the control, may become the traditional black-white control logic the computer program control logic, removes all uses in the logical control intermediate relay, causes the cost of
