洛阳理工学院毕业设计（论文）I基于三菱 PLC 十层电梯控制设计摘 要电梯是机械电器紧密结合的大型机电产品主要由机房、井道、轿厢、门系统和电气控制系统组成。电梯已不仅是一种生产环节中的重要设备，更是一种工作和生活中的必需设备，完全可以预想到，随着社会的发展，电梯产品在人们物质文化生活中的地位将和汽车一样，成为重要的运输设备之一。本次设计主要将可编程序控制器（PLC）和计算机应用到电梯的控制系统中去，以十层电梯为例来完成单台电梯 PLC 控制系统的总体设计方案、组成及模块化程序设计。选用三菱 FX2N 可编程控制器，利用 220V 交流电源供压。在进行 PLC的 I/O 接口分配、组合排列和代号后，确定机内各种软继电器、数据区、通道代号，常用指令的编制规则和代号等。选用交流双速电机实现电梯拖动，采用楼层传感器实现楼层间翻转；显示驱动电路采用 LED 发光二极管构成显示屏的屏体。重点研究 PLC 的安全控制电路、楼层控制电路，开关门电路的设计，以及启动开关门程序、上行下行程序、楼层控制程序、自动定向程序的编写。PLC 电梯控制系统只需要稍加改进即可应用于更高性能要求的电梯中。这一切都表明该系列 PLC 不仅可以满足电梯对高可靠性的实际需求，而且在控制水平和性能完全可以替代进口的同类产品，并将突破电梯领域应用到更为广泛的行业，未来前景将更为广阔。关键词：PLC,电梯,逻辑控制,程序设计洛阳理工学院毕业设计（论文）IIBased on the Mitsubishi elevator control design of PLC tenABSTRACTThe elevator is the mechanical electric appliance close union large-scale mechanical and electrical products. Mainly of engine room, well road, sedan theater box, gate system and electric control system composition. The elevator already was not only in one kind of production links important equipment, was in one kind of work and the life essential equipment, definitely might expect that along with societys development, the elevator products will be the same in people material culture life status with the automobile, becomes one of important transport vehicles.This design mainly (PLC) and the computer applies the programmable controller in elevators control system, as regularly completes the single Taiwan elevator PLC control systems overall project design, the composition and the modularized program design take five elevators. Selects the Mitsubishi FX2N programmable controller, After carrying on PLC the I/O connection assignment, the combination arrangement and the code channel code number, commonly used instruction establishment rule and code number and so on. Selects the exchange two speed electrical machinery to realize the elevator dragging, uses the floor sensor to realize between the floor to turn over; The demonstration driving circuit uses the LED light emitter diode to constitute display monitors screen body. Key studies PLC the safety control electric circuit, the floor control circuit, the switch gate design, as well as starting switch gate procedure, upward downward procedure, floor control procedure, automatic orientation procedure compilation. The PLC lift control system only needs to improve slightly then applies in the high performance request elevator. All these indicated that this series PLC not only may satisfy the elevator to the redundant reliable physical demand, moreover definitely may substitute the import in the control level and the performance the similar products, and will break through the elevator domain to apply a more widespread profession, in the future the prospect will be broader.KEY WORDS: PLC, Elevator, Logical control, Programming 洛阳理工学院毕业设计（论文）III目 录前 言.1第 1 章 总体方案确定.21.1 总体方案的确定.21.2 电梯 PLC 控制系统的构.31.3 设计的整体布局及其选型.5第 2 章 可编程序控制器的结构与工作原理.62.1 PLC 的体系结构 .62.2 可编程序控制器的基本结构.62.3 开关量 I/O 模块.82.3.1 输入模块.82.3.2 输出模块.92.4 可编程序控制器的工作原理.92.4.1 可编程序控制器的工作原理.102.4.2 PLC 工作过程.102.5 PLC 控制程序设计 .112.5.1 PLC 编程步骤.11第 3 章 电梯的电气控制系统.123.1 概述.123.2 电梯电气控制系统中的主要电器部件.123.3 十层电梯控制系统的设计要求.153.4 电气原理图的设计.163.5 梯形图的设计及指令表.173.5.1 各层呼叫指示.173.5.2 电梯启动和运行方向.24结 论.29谢 辞.
