1、基于 PLC 的電梯控制系統(tǒng)設(shè)計(jì)摘 要隨著城市建設(shè)的不斷發(fā)展，高層建筑不斷增多，電梯作為交通工具已與人們的日常生活密不可分，電梯性能的好壞對(duì)人們生活的影響越來(lái)越顯著，因此必須努力提高電梯系統(tǒng)的性能，保證電梯的運(yùn)行既高效節(jié)能又安全可靠。傳統(tǒng)的電梯控制系統(tǒng)采用的是繼電器邏輯控制電路，這種控制易出故障，維護(hù)不便，運(yùn)行壽命短，占地空間大，正逐步被淘汰。為了提高控制系統(tǒng)的可靠性和設(shè)備的工作效率，設(shè)計(jì)了一套以 PLC 為核心控制器的電梯自動(dòng)控制系

2、統(tǒng)，用來(lái)取代以往較復(fù)雜的繼電器—接觸器控制。系統(tǒng)的核心部分（控制部分）使用了日本三菱公司生產(chǎn)的FX2N-80 型 PLC，因?yàn)樵诤诵目刂撇糠植捎玫氖擒浖绦蚩刂?，從而在保證電梯正常運(yùn)行的情況下，大大提高了電梯故障檢查與維修的方便性和容易性，同時(shí)還克服了人為干擾因素，取得了良好的預(yù)期效果。本課題的研究題目涉及以下兩方面：首先 PLC 控制是指電梯信號(hào)控制由 PLC 及其軟件來(lái)實(shí)現(xiàn)，控制系統(tǒng)的核心是 PLC。其次穩(wěn)定與安全運(yùn)行是評(píng)價(jià)電梯性能

3、的重要依據(jù)，針對(duì)提高電梯的安全運(yùn)行，設(shè)計(jì)一種基于MCGS 組態(tài)軟件的電梯實(shí)時(shí)運(yùn)行的監(jiān)控方案。該方案通過(guò) RS485/RS232 通信接口采集到模擬電梯的實(shí)時(shí)運(yùn)行數(shù)據(jù)，采用 MCGS 組態(tài)軟件涉及電梯的現(xiàn)場(chǎng)監(jiān)控系統(tǒng)，通過(guò)整體的設(shè)計(jì)和動(dòng)畫(huà)效果的演示，實(shí)現(xiàn)現(xiàn)場(chǎng)設(shè)備的實(shí)時(shí)監(jiān)視，MCGS 組態(tài)軟件的引入對(duì)電梯控制以及工業(yè)現(xiàn)場(chǎng)監(jiān)控的進(jìn)一步研究有著積極的意義。關(guān)鍵詞：PLC；電梯；模擬電梯；MCGS；監(jiān)控系統(tǒng)Design of elevator co
