摘 要

随着我国现代化程度的提高以及人们生活的需求，电梯已经成为高层建筑中的重要代步工具，它是高层建筑中安全、可靠、垂直上下的运载工具，对改善劳动条件、减轻劳动强度起到了非常重要的作用。同时也给人们的生活带来非常的便利条件，同时也为我国的现代化建设的加速发展提供了强大的保障。电梯的应用范围很广,可以用于宾馆、饭店、酒店、办公大楼、商场、娱乐场所以及小区公寓等。因此，在现代社会中电梯已成为人类必不可少的垂直运输交通工具。利用单片机控制电梯有成本低，通用性强，灵活性大以及易于实现复杂控制等特点。

基于单片机的电梯智能控制系统的设计分别从系统要求、硬件设计、软件设计等几个部分设计，介绍了以AT89C52系列单片机为核心，并结合74LS245和8*8LED点阵等芯片以及与之相配套的C语言程序软件等进行电梯模拟的具体实现方法，该方法不仅可以实现电梯的基本功能，而且可以设置电梯直达、急停等功能，从而可实现电梯的智能控制及相应的最佳路线选择，提高电梯的有效利用率。 关键词 ： LED点阵；单片机；系统；控制

Abstract

With the improvement of modernization of our country and people's life demand, the elevator has become a high-rise building in an important means of transport. It is a high-rise building in safe, reliable and vertical vehicle, to improve the working conditions and very important to lessen the intensity of labor. Also to people's life bring very convenient conditions, but also for the modernization construction of our country to speed up the development of a powerful guarantee. The elevator in a wide range of applications, can be used in hotels, restaurants, hotels, office buildings, shopping malls, entertainment and residential apartments. Therefore, in modern society, the elevator has become an indispensable vertical transportation of human. The use of single-chip control elevator has low cost, versatility, flexibility and easy to realize complex control.

Based on SCM intelligent elevator control system design from system requirements, hardware design and software design part of the design, introduces the AT89C52 MCU as the core, combined with 74LS245 and 8 * 8LED lattice, such as chips and matched with the C language program software for specific methods to realize the simulation of elevator, the method can not only realize the elevator's basic functions, but also can set elevator access, emergency stop function, which can realize elevator intelligent control and the corresponding optimal route selection, improve the elevator the effective utilization.
