It applies the large scale integrated circuit, the miniature machine technology and the munication technology development achievement, gradually formed had the many kinds of merits and miniature, medium, largescale, ultra largescale and so on each kind of specification series product, applied to monitors between the puter from the control system many controls domain. Along with society39。s unceasing development, the building is more and more high, but the elevator became the high level building to have the equipment. After humanity39。s more than centuries unremitting endeavors, the elevator already from the handle switch operation elevator, the pushbutton control elevator develops to the present group control elevator, has made the indelible contribution for the high level transportation. PLC in the control in the elevator the application mainly to manifest in its logical switch control function. This function enable PLC to have the logic operation, counts with fixed time as well as the data feeds output function. Rises and falls in the process in the elevator, each logical switch control and PLC very good union, very good realization to fluctuation control. This article main discussion studies using sinmens Corporation39。s PLC molding machine carries on the control to the 3floor elevator fluctuation, forms the elevator control system Key words: the PLC。 control system。 elevator systems operation overhauls and debugs 4 目錄 前言 .............................................................................................................................. ６ 第 1 章 PLC 的基本知識 ........................................................................................... ７ PLC 的定義 ........................................................................................................ ７ PLC 的組成和基本工作原理 ............................................................................ ７ PLC 的硬件組成 ..................................................................................... ７ PLC 的工作原理 ..................................................................................... ８ PLC 與變頻器的連接程序 ................................................................................ ９ 第 2 章 電梯的概述 .................................................................................................... 11 電梯的定義 ........................................................................................................... 11 電梯的分類 ........................................................................................................... 11 按速度分 .................................................................................................... 11 按用途 分 .................................................................................................... 11 電梯的基本結(jié)構(gòu) ................................................................................................... 11 曳引系統(tǒng) .................................................................................................... 12 導(dǎo)向系統(tǒng) .................................................................................................... 12 門系統(tǒng) ........................................................................................................ 12 轎廂 ............................................................................................................ 12 重量平衡系統(tǒng) ............................................................................................ 12 電力拖動系統(tǒng) ............................................................................................ 13 電氣控制系統(tǒng) ............................................................................................ 13 安全保護(hù)系統(tǒng) ............................................................................................ 13 第 3 章 力控組態(tài)軟件的概述 .................................................................................. 14 第 4 章 電梯控制的要求及運(yùn)行分析 ........................................................................ 14 基本要求 ............................................................................................................... 20 速 度要求 ............................................................................................................... 22 電梯運(yùn)行分析 ................................................................................................... 22 輸入點(diǎn)分析 .............................................................. 錯誤 !未定義書簽。 24 輸出點(diǎn)分析 ...............................................................................
