摘 要隨著現(xiàn)代城市的發(fā)展，高層建筑日益增多，電梯成為人們?nèi)粘Ｉ畋夭豢缮俚拇焦ぞ?。電梯性能的好壞?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。單片機(jī)即單片微型計(jì)算機(jī)（SingleChip Microputer） ，是集 CPU ，RAM ，ROM 定時(shí)，計(jì)數(shù)和多種接口于一體的微控制器。其中 51 單片機(jī)是各種單片機(jī)中最為典型和最有代表性的一種,、電氣控制技術(shù)、微處理器技術(shù)、系統(tǒng)工程學(xué)等多學(xué)科和技術(shù)分支于一體的機(jī)電設(shè)備，它是建筑中的永久垂直交通工具。本論文選擇 82C51 為核心控制元件，設(shè)計(jì)了一個(gè)六層電梯系統(tǒng)，使用單片機(jī)匯編語(yǔ)言進(jìn)行編程，實(shí)現(xiàn)運(yùn)送乘客到任意樓層，并且顯示電梯的樓層和上下行。利用單片機(jī)控制電梯有成本低，通用性強(qiáng)，靈活性大及易于實(shí)現(xiàn)復(fù)雜控制等優(yōu)點(diǎn)。關(guān)鍵詞

building, elevator bee an indispensable means of transport of daily life. The quality of the lift performance of the impact on people39。s lives being more and more obvious, it must strive to improve the performance of elevator systems, and ensure the operation of the lift is safe, reliable and energy efficient. The traditional elevator control system uses logic of the relay to control circuit, this kind of controls easily to be crash, maintains inconveniently, the movement life is short, and that occupying a large area of space, it being eliminated gradually. Microcontroller that microputer (SingleChip Microputer) gathering CPU, RAM, ROM, the timing, number and variety of interface integrated microcontrollers. 51 various SCM SCM is the most typical and most representative of a widely used in various fields. Elevator is the application of the principle set machinery, electrical control technology, microprocessor technology, systems engineering and other technical disciplines and branches of the integration of me
