摘 要
本文涉及電梯的轎廂和PLC控制系統的設計。了解電梯轎廂的特點及需要實現的功能，分析電梯轎廂的工作原理、基本結構，設計電梯的PLC控制系統。這篇論文主要研究乘客電梯的轎廂結構設計和PLC控制系統設計。
電梯是一種以電動機為動力的垂直升降機，裝有箱狀吊艙，用于多層建筑乘人或載運貨物。電梯種類繁多，主要有兩種分類方法，按用途分類和按驅動系統分類。電梯轎廂則主要包括兩個結構，轎廂架和轎廂體。轎廂架是固定和懸吊轎廂的框架，由上梁、立梁、下梁和拉條等部分組成。電梯的轎廂由轎廂底、轎廂壁、轎廂頂和轎廂門等組成。這次主要是研究乘客電梯，要求有很高的安全性。PLC可控性和安全性較高，這次電梯主要通過PLC控制系統控制電機運行，繼而控制電梯的拖動系統來控制電梯的運行。
關鍵詞：電梯轎廂 控制系統
Abstract
This article is primarily related to the elevator car and the PLC control system. Understand the characteristics of the elevator car and the functions to be achieved. Analyse the working principle and the basic structure of elevator cars. Then design PLC elevator control system. This thesis focuses on the passenger elevator car structure design and PLC control system design.
Elevator is a kind of electric motor driven vertical lift, with box-shaped pod, used by people or transportation of products in multi-storey building. Elevator has many kinds of types. There are two main classifications which include use classification and drive system classification. Elevator car mainly consists of two structure, elevator car frame and elevator car body. Elevator car rack is the framework for fixing and suspending car. Higher beam、vertical beam、lower beam and brace compose the elevator car rack. Elevator car body consists of car bottom、car wall、car tops and car doors. The paper mainly study passenger elevator which demand high security. PLC has high safety and controlling. It controls the motor running mainly by the PLC control system, then control the elevator dragging system to control the elevator running.
Keywords: Elevator cars; Control system
