43、電梯主要分為機(jī)械系統(tǒng)與控制系統(tǒng)兩大部份，隨著自動(dòng)控制理論與微電子技術(shù)的發(fā)展，電梯的拖動(dòng)方式與控制手段均發(fā)生了很大的變化，交流調(diào)速是當(dāng)前電梯拖動(dòng)的主要發(fā)展方向。目前電梯控制系統(tǒng)主要有三種控制方式：繼電路控制系統(tǒng)(“早期安裝的電梯多位繼電器控制系統(tǒng))、plc控制系統(tǒng)、微機(jī)控制系統(tǒng)。繼電器控制系統(tǒng)由于故障率高、可靠性差、控制方式不靈活以及消耗功率大等缺點(diǎn)，目前已逐漸被淘汰。微機(jī)控制系統(tǒng)雖在智能控制方面有較強(qiáng)的功能，但也存在抗擾性差，系統(tǒng)設(shè)計(jì)復(fù)雜，一般維修人員難以掌握其維修技術(shù)等缺陷。而plc控制系統(tǒng)由于運(yùn)行可靠性高，使用維修方便，抗干擾性強(qiáng),設(shè)計(jì)和調(diào)試周期較短等優(yōu)點(diǎn)，倍受人們重視等優(yōu)點(diǎn)，已成為目前在

44、電梯控制系統(tǒng)中使用最多的控制方式，目前也廣泛用于傳統(tǒng)繼電器控制系統(tǒng)的技術(shù)改造。電梯的起源與發(fā)展電梯在漢語(yǔ)詞典中的解釋為：建筑物中用電作動(dòng)力的升降機(jī),代替步行上下的樓梯。說(shuō)到電梯的起源要從公元前2600年埃及人在建造金字塔時(shí)使用了最原始的提升系統(tǒng)說(shuō)起，但這一類起重機(jī)的能源均為人力。到了1203年，法國(guó)的二修道院安裝了一臺(tái)起重機(jī)，所不同者只是該機(jī)器是利用驢作為動(dòng)力，載荷由繞在一個(gè)大滾筒上的繩子進(jìn)行起吊。此種方法一直沿用到近代直到瓦特發(fā)明了蒸汽機(jī)，約在1800年，煤礦主才能利用起重機(jī)把礦井中的煤輸送上來(lái)。數(shù)百年來(lái)人們制造過(guò)各種類型的升降梯，它們都具有一個(gè)共同的缺陷：只要起吊繩突然斷裂，升降梯便急速地

45、墜落到底層。1854年奧的斯設(shè)計(jì)了一種制動(dòng)器：在升降梯的平臺(tái)頂部安裝一個(gè)貨車用的彈簧及一個(gè)制動(dòng)桿與升降梯井道兩側(cè)的導(dǎo)軌相連結(jié)，起吊繩與貨車彈簧連結(jié)，這樣僅是起重平臺(tái)的重量就足以拉開(kāi)彈簧，避免與制動(dòng)桿接觸。如果繩子斷裂，貨車彈簧會(huì)將拉力減弱，兩端立該與制動(dòng)桿咬合，即可將平臺(tái)牢固地原地固定免繼續(xù)下墜?！鞍踩纳堤荨卑l(fā)明成功了！一時(shí)間，奧的斯成了眾人注目的中心。第一臺(tái)升降機(jī)并非奧的斯所發(fā)明，但他卻是第一臺(tái)“安全”升降梯的發(fā)明者。“安全”這一概念不僅開(kāi)創(chuàng)了升降梯工業(yè)，而且也為那些想建造更高層建筑物以增加更多可利用空間的設(shè)計(jì)們打開(kāi)了通途。然而真正能夠稱為電梯（用電能驅(qū)動(dòng)升降梯）的產(chǎn)品應(yīng)該是在20世紀(jì)初

46、才出現(xiàn)的。 電梯技術(shù)發(fā)展趨勢(shì)（1）環(huán)保：綠色理念是電梯發(fā)展總趨勢(shì)。有專家預(yù)言“誰(shuí)最先推出綠色產(chǎn)品并搶占市場(chǎng)，誰(shuí)就掌握市場(chǎng)競(jìng)爭(zhēng)主動(dòng)權(quán)”。發(fā)展趨勢(shì)主要有：不斷改進(jìn)產(chǎn)品的設(shè)計(jì)，生產(chǎn)環(huán)保型低能耗、低噪聲、無(wú)漏油、無(wú)漏水、無(wú)電磁干擾、無(wú)井道導(dǎo)軌油漬污染的電梯。電梯曳引采用尼龍合成纖維曳引繩，鋼皮帶等無(wú)潤(rùn)滑油污染曳引方式。電梯裝璜將采用無(wú)（少）環(huán)境污染材料。電梯空載上升和滿載下行電機(jī)再生發(fā)電回收技術(shù)。安裝電梯將無(wú)需安裝手腳架。電梯零件在生產(chǎn)和使用過(guò)程中對(duì)環(huán)境沒(méi)有影響（如剎車皮一定不能使用石棉）并且材料是可以回收的。（2）藍(lán)牙技術(shù)在電梯上應(yīng)用。安裝過(guò)電梯的人都知道放線、對(duì)線是費(fèi)時(shí)、費(fèi)力、極容易錯(cuò)的工作。如果

47、控制屏與召喚系統(tǒng)通過(guò)藍(lán)牙技術(shù)連接起來(lái)實(shí)現(xiàn)無(wú)線召喚將會(huì)是電梯控制的另一場(chǎng)革命同時(shí)為我們帶來(lái)巨大好處。a安裝期將減少30以上，其直接好處是降低安裝成本，客戶也因從訂梯到使用電梯周期費(fèi)用減少和提高現(xiàn)金周轉(zhuǎn)率。b在電梯上使用藍(lán)牙技術(shù)一定會(huì)使電梯控制系統(tǒng)大量使用最新最快微機(jī)，這將會(huì)進(jìn)一步提高電梯整機(jī)可靠性，故障率大大降低，控制精度也進(jìn)一步提高，帶來(lái)的結(jié)果是電梯更加舒適，平層更加準(zhǔn)確。c很好地解決了電梯控制與外圍設(shè)備的兼容和聯(lián)系。特別是可以把電梯和扶梯歸納到大樓管理系統(tǒng)或智能化管理小區(qū)系統(tǒng)中。 plc的定義可編程控制器是一種數(shù)字運(yùn)算操作的電子系統(tǒng)，專為在工業(yè)環(huán)境應(yīng)用而設(shè)計(jì)的。它采用一類可編程的存儲(chǔ)器，用于

48、其內(nèi)部存儲(chǔ)程序，執(zhí)行邏輯運(yùn)算,順序控制，定時(shí)，計(jì)數(shù)與算術(shù)操作等面向用戶的指令，并通過(guò)數(shù)字或模擬式輸入/輸出控制各種類型的機(jī)械或生產(chǎn)過(guò)程?？删幊炭刂破骷捌溆嘘P(guān)外部設(shè)備，都按易于與工業(yè)控制系統(tǒng)聯(lián)成一個(gè)整體，易于擴(kuò)充其功能的原則設(shè)計(jì)?？傊?，可編程控制器是一臺(tái)計(jì)算機(jī)，它是專為工業(yè)環(huán)境應(yīng)用而設(shè)計(jì)制造的計(jì)算機(jī)。它具有豐富的輸入/輸出接口，并且具有較強(qiáng)的驅(qū)動(dòng)能力。但可編程控制器產(chǎn)品并不針對(duì)某一具體工業(yè)應(yīng)用，在實(shí)際應(yīng)用時(shí)，其硬件需根據(jù)實(shí)際需要進(jìn)行選用配置，其軟件需根據(jù)控制要求進(jìn)行設(shè)計(jì)編制。 plc的特點(diǎn)：一、可靠性高，抗干擾能力強(qiáng)高可靠性是電氣控制設(shè)備的關(guān)鍵性能plc由于采用現(xiàn)代大規(guī)模集成電路技術(shù)，采用嚴(yán)格的生產(chǎn)工藝
