PAGE II 交流双速电梯控制系统的电气设计 摘要：本文以CPU226型的PLC为控制核心，设计了一个6层载人电梯控制系统。通过各类继电器、传感器、接触器等，实现信息的采集，同时通过PLC作用，驱动相关装置运行，最终实现电梯的上行、下行、开门、关门、指示显示等功能。系统设计的各项功能都需要编程来实现，采用功能分块逐步编程，分步调试的，最终整合的方式，来实现程序的编写。系统的双速运行采用了变极调速，使用的笼型三相异步电机来作为牵引机。以PLC为控制核心的电梯，具有结构简单，控制方便，编程容易、抗干扰性强、可靠性和可移植性强的特点，同时，设计中的变极调速，能够实现电梯的快速和舒适运行，因此交流双速电梯控制系统在现代电梯控制系统中有着重要的地位。 关键词：交流、双速、电梯、PLC。 AC Two-speed Elevator Control System Electric Design Abstract：This design is about six floors of the exchange double speed of elevator control system, in this system is designed based on CPU226 microcontroller. Through all kinds of relays, sensors, contactor, realize the information collection,While through PLC , drive related plant operation to achieve the elevator up、down、door to open and to close、instructions show etc also. Each function of this design need programming to realize, uesing the function block gradually programming、the commissioning of the step、and to integrate finally. System of double speed operation using the speed change pole and use of cage type three-phase asynchronous motor as a drawer. PLC as the control center of the elevator, the structure is simple、control easy、programming easily and robust of reliability and portability strong characteristic. Meanwhile，the change pole in the design of double speeding can realize the elevator about the fast and comfortable operation, so exchange double speed of elevator control system in modern elevator control system has an important position. Keywords: AC、Two-speed、Elevator、PLC. 目 录 TOC \o 1-3 \f \h \z \u HYPERLINK \l _Toc313291938 第1章 绪论 PAGEREF _Toc313291938 \h 1 HYPERLINK \l _Toc313291939 1.1 课题背景及意义 PAGEREF _Toc313291939 \h 1 HYPERLINK \l _Toc313291940 1.2国内外研究的现状 PAGEREF _Toc313291940 \h 1 HYPERLINK \l _Toc313291941 1.3研究的主要内容 PAGEREF _Toc313291941 \h 2 HYPERLINK \l _Toc313291942 第2章 电梯的基本知识 PAGEREF _Toc313291942 \h 3 HYPERLINK \l _Toc313291943 2.1电梯的基本结构 PAGEREF _Toc313291943 \h 3 HYPERLINK \l _Toc313291944
