摘     要
 随着我国经济的发展，城市中涌现出越来越多的高层建筑，而与之配套的电梯成为人们日常生活中不可缺少的工具。由于商品的人性化要求越来越高，多层建筑中配套的电梯同样也要适应时代的要求。以前，国内电梯大多采用继电器控制，但这种控制方式的生产成本高，体积大，安装和调试不方便，且需要占用较大的硬件空间，时代的发展要求更有效率的控制系统的出现
 四层教学电梯模型采用单片机控制,具有一定的规模和实际电梯的主要操作功能,教学可视效果好,是应用单片机的典型教学实验室装置,其控制软件的是设计方法同样适用于实际电梯的研究.
 本论文阐述了单片机在电梯控制中的应用.主要介绍了4层电梯的控制系统总体设计方案、设计过程、组成,列出了具体的硬件电路原理图.并给出了系统组成框图个程序流程图,在分析、处理随即信号逻辑关系的基础上,提出了单片机的编程方法.

Abstract
 There are more and more high buildings being built in the city as the economy developing. As the same time, elevators that are suitable for the skyscrapers become the necessary tool in human life. And elevators have to be accommodated to the higher and higher humanistic acquirements. Most of usual elevators made in our country were designing for relay-control, although this pattern of control has the disadvantages of high cost and big physical volume, meanwhile its installation and debug were inconvenient. So it is desirous for a new pattern of more efficient manipulative system.
 The thesis expounds that a four-storeyed teaching elevator model is controlled by MCU.It has the main operating functions of the practical elevator on a certain scale and also the visible teaching effect.It is a typical experimental device in MCU technology, whose design procedure of control software is also applicable to the research of the practical elevator.
 This paper described the MCU in the elevator control the application of the major on the fourth floor of the elevator control system design programme, the design process, composition, lists the specific hardware circuit schematics. And gives the system components Diagram of a process flow chart in the analysis, signal processing was the logical relationship on the basis of the proposed MCU programming method.
