【正文】 隨著我國(guó)經(jīng)濟(jì)的高速發(fā)展，微電子技術(shù)、計(jì)算機(jī)技術(shù)和自動(dòng)控制技術(shù)也得到了迅速發(fā)展，交流變頻調(diào)速技術(shù)已經(jīng)進(jìn)入一個(gè)嶄新的時(shí)代，其應(yīng)用越來越廣。 系統(tǒng)的調(diào)試與操作 .........................................................錯(cuò)誤 !未定義書簽。 電梯模型 PLC 控制系統(tǒng)設(shè)計(jì) .........................................錯(cuò)誤 !未定義書簽。 電梯的控制要求 ...............................................................錯(cuò)誤 !未定義書簽。目 錄 摘 要 ............................................................................................. 1 1 前 言 .......................................................................................... 2 2 電梯概述 ...................................................................................... 4 電梯的起源與發(fā)展 ........................................................................................... 4 國(guó)外電梯的情況 ............................................................................................... 4 國(guó)內(nèi)電梯的情況 ............................................................................................... 5 電梯技術(shù)發(fā)展趨勢(shì) .......................................................................................... 7 第 3 章 PLC 的發(fā)展 ..................................................................... 7 PLC 的定義 ...................................................................................................... 7 PLC 的發(fā)展階段 .............................................................................................. 7 PLC 發(fā)展趨勢(shì) .................................................................................................. 9 PLC 的基本組成 ............................................................................................ 10 第 4 章 電梯模型 PLC 控制系統(tǒng)設(shè)計(jì) .................................... 14 電梯的類型 .......................................................................錯(cuò)誤 !未定義書簽。 電梯示意圖 .......................................................................錯(cuò)誤 !未定義書簽。 PLC 控制系統(tǒng)的設(shè)計(jì)分析 ..............................................錯(cuò)誤 !未定義書簽。 PLC 的選擇 ......................................................................錯(cuò)誤 !未定義書簽。 結(jié) 束 語(yǔ) ......................................................... 錯(cuò)誤 !未定義書簽。而電梯作為現(xiàn)代高層建筑的垂直交通工具，與人們的生活緊密相關(guān)，隨著人們對(duì)其要求的提高，電梯得到了快速發(fā)展，其拖動(dòng)技術(shù)已經(jīng)發(fā)展到了調(diào)頻調(diào)壓調(diào)速，其邏輯控制也由 PLC 代替原來的繼電器控制。目前電梯設(shè)計(jì)使用可編程控制器 (PLC)，功能變化靈活，編程簡(jiǎn)單，故障少，噪音低。當(dāng)乘員進(jìn)入電梯 ，按下樓層按鈕，電梯門自動(dòng)關(guān)閉后．控制系統(tǒng)進(jìn)行下列運(yùn)作：根據(jù)轎廂所處位置及乘員所處層數(shù)。將轎廂停在選定的樓層上；同時(shí)，根據(jù)樓層的呼叫，順路停車，自動(dòng)開關(guān)門。 A b s t r a c t With the development of the economy, microelectronic technology, puter technology and the automatic theory are developed rapidly, the AC variable frequency technology has been in a new state. Its application is being more and more widely. But the elevator as an important traffic in skyscraper ， it also has developed quickly with the improving requirement of the people .Its dragging technology has developed from DC timing to AC variable frequency timing and its logic control relay control also has been replaced by PLC. Lift the electrical system from the drive system and control system posed of two parts. Lift the current design PLC (PLC), function in a flexible, simple programming, less failure, low noise. Facilitate maintenance, energysaving in public, antiinterference capability and control box covers an area of less. When the crew entered the elevator, press the floor button, automatically shut down after the elevator door. Control systems following the operation: Cabin crew and the location in which layers. Cars determine the direction of travel to ensure that Carlayer slowdown. Car will be parked in the selected on the floor at the same time, under floors of the calls, parking places, automatic switching gate. Also in the Cabin have both inside and outside lights show the d
