基于PLC的電梯控制系統(tǒng)設(shè)計(jì),基于,plc,電梯,控制系統(tǒng),設(shè)計(jì) 河南科技學(xué)院 2009屆本科畢業(yè)論文（設(shè)計(jì)） 論文題目：基于PLC的電梯控制系統(tǒng)設(shè)計(jì) 學(xué)生姓名：賈 學(xué) 軍 所在院系：機(jī)電學(xué)院 所學(xué)專業(yè)：機(jī)電技術(shù)教育 導(dǎo)師姓名：王 玉 萍 完成時(shí)間：2009年 5月 20 日 摘 要 隨著社會(huì)的發(fā)展，電梯的應(yīng)用越來(lái)越被企、事業(yè)單位、大型超市等場(chǎng)所普及，而它的安全、可靠性確備受觀注。可編程控制器(PLC)是以計(jì)算機(jī)技術(shù)為核心的通用自動(dòng)化控制裝置。它的功能性強(qiáng),可靠性高,編程簡(jiǎn)單,使用方便,體積小巧,將PLC 應(yīng)用于電梯控制，克服了繼電器控制的控制線路復(fù)雜、體積大、故障率高、難于維護(hù)等缺點(diǎn)，電梯控制系統(tǒng)的安全性、可靠性得到了很大的改善。 關(guān)鍵詞：PLC, 電梯控制系統(tǒng), 可靠性 PLC-based elevator control system design Abstract With the development of society, the elevator are applied by enterprises, institutions, large supermarket etc popularization widely, it is the view of safety and reliability. Programmable logic controller (PLC) is a general automatic control device as the core of a computer technology, its strong function, high reliability, simple programming, easy to use, small size, applying PLC to elevator control to overcome the elevator control circuit complexity, big volume, difficult to maintain and high defects. it obtained very big improvement to elevator control system of the safety and reliability.
