基于 51 单片机的三层电梯系统设计专业班级：电子信息科学与技术1 班姓名：李强指导教师：金国华老师信息科学技术学院I摘要本文设计了一款基于单片机( AT89C51) 的三层电梯的模拟控制系统。以 51 单片机为核心， 由 7 段显示数码管来作为电梯楼层和电梯上下行状态的显示部分，数码管显示“ p”则说明电梯运行状态向上, 显示“ d”则说明电梯运行状态向下。由按键来分别表示电梯内外的各个功能按钮。本设计主要是利用了单片机：灵活性大、通用性强以及易于实现复杂控制的特点，使系统在达到设计目的的同时显得结构简单，操作方便，容易理解。文中首先是针对设计的目的选择出比较合适的设计方案，并且对AT89C51 单片机和 7 段显示数码管进行了简要介绍，然后将本次设计的硬件电路分为单片机控制模块、显示模块、按键检测模块三个大的模块。在进行了电路的连接之后，根据电路的连接就各个模块分别编写程序再由主程序统一衔接在一起。通过调试运行，所设计的三层电梯系统基本满足设计要求。关键词： AT89C51 单片机；电梯控制；数码显示IIAbstract In this paper,we designed a three elevator analog control system which is based on a microcontroller(AT89C51).The microcontroller as the core，and 7-segment digital tube display as the elevator floor and the elevator up and down the line status display section.When the elevator running up the digital display "p" and when the elevator running down the digital display "d" .Various function buttons inside or outside the elevator are represented by buttons. This design is mainly the use of the characteristics of SCM:flexibility,versatility and easy to implement complex control features.So that the system is not only designed to meet the design requirements but also seem simple structure,easy to operate and understand.First of all,we choose the appropriate design and then a brief description of AT89C51 microcontroller and 7-segment display digital tube.Then in this design the hardware circuit is divided into three large modules:single-chip control modu...
