摘 要

電梯是標(biāo)志現(xiàn)代物質(zhì)文明的垂直運(yùn)輸工具、是機(jī)—電一體化的復(fù)雜運(yùn)輸設(shè)備。它涉及電子技術(shù)、機(jī)械工程、電力電子技術(shù)、微機(jī)技術(shù)、電力拖動(dòng)系統(tǒng)和土建工程等多個(gè)科學(xué)領(lǐng)域。目前電梯的生產(chǎn)情況和使用數(shù)量已成為一個(gè)國家現(xiàn)代化程度的標(biāo)志之一。隨著現(xiàn)代化城市的高速發(fā)展，每天都有大量人流及物流需要輸送。為節(jié)約用地和適應(yīng)經(jīng)貿(mào)事業(yè)的發(fā)展，一幢幢高樓拔地而起，這些高層建筑的垂直運(yùn)輸是一個(gè)突出問題，與人們的工作和生活緊密相關(guān)。

隨著社會(huì)的發(fā)展，電梯的使用越來越普遍，已從原來只在商業(yè)大廈、賓館使用，過渡到在辦公樓、居民樓等場所使用，并且對電梯功能的要求也不斷提高，相應(yīng)地其控制方式也在不停地發(fā)生變化。對于電梯的控制，傳統(tǒng)的方法是使用繼電器—接觸器控制系統(tǒng)進(jìn)行控制，隨著技術(shù)的不斷發(fā)展，微型計(jì)算機(jī)在電梯控制上的應(yīng)用日益廣泛，現(xiàn)在已進(jìn)入全微機(jī)化控制的時(shí)代。

當(dāng)今時(shí)代隨著高層建筑的日益增多和建筑設(shè)計(jì)的檔次的提高，使得人們對電梯的要求也越來越高。目前已不僅限于要求電梯搭乘快速、舒適，制造堅(jiān)固，裝潢考究，人們對電梯的安全可靠性及多功能性正提出越來越高的要求，為此電梯正朝著控制智能化的方向發(fā)展。
而電梯的核心是電梯控制器,電梯控制器的實(shí)現(xiàn)也有多中方式,諸如PLC,單片機(jī),等等在以前的電梯控制器設(shè)計(jì)中,大部分都是采用PLC來實(shí)現(xiàn),但是PLC是基于外圍的硬件實(shí)現(xiàn)電梯的控制,這樣的設(shè)計(jì)很難實(shí)現(xiàn)電梯的智能化,要實(shí)現(xiàn)電梯的智能化,就得選用其他的設(shè)計(jì)方法完成對電梯控制器的設(shè)計(jì),而采用硬件描述語言來完成電梯控制器的設(shè)計(jì),就能很容易的實(shí)現(xiàn)電梯的智能

Abstract

The elevator is symbolized the modern material civilization verticaltransport means, are machine - the electricity integration complextransport vehicle It involves the electronic technology, themechanical engineering, the electric power electronic technology, themicrocomputer technology, the electric power drives the system and thecivil engineering and so on many scientific domains At present theelevator production situation and the use quantity have become one ofnational modernization degree symbols Along with the modernized cityhigh speed development, has the massive streams of people and thething class every day needs to transport In order to save with andthe adaption economics and trade enterprise development, a flickeringtall building rises straight from the ground, these high-riseconstructions vertical transportation are a prominent question, withpeople's work and life close correlation Along with society's development, the elevator use is more and morecommon, from originally only in the commercial building, theguesthouse use, transited to in place use and so on the officebuilding, building of residence, and also unceasingly enhances to theelevator function request, correspondingly its control mode also indoes not stop changes Regarding the elevator control, the traditionalmethod is uses the relay - contact device control system to carry onthe control, along with the technical unceasing development, themicrocomputer is day by day widespread in elevator controlapplication, now entered the entire microcomputer control the time The present era day by day increases along with the high-riseconstruction with the architectural design scale enhancement, causesthe people more and more to be also high to the elevator request Atpresent not only has been restricted in requests the elevator totravel by fast, comfortable, manufacture firm, the decoration iselegant, the people to the elevator security reliability andmulti-purpose were proposing the more and more high request, is facingthe control intellectualization direction for this elevator todevelop But the elevator core is the elevator controller, the elevatorcontroller realization also has many center ways, such as PLC,monolithic integrated circuit, and so on In the before elevatorcontroller design, majority of all was uses PLC to realize, but PLCwas realizes the elevator control based on the periphery hardware,such design was very difficult to realize the elevatorintellectualization, had to realize the elevator intellectualization,had to select other design methods to complete to the
elevatorcontroller design, but used the hardware description language tocomplete the elevator controller the design, could the very easyrealization elevator intelligence
