基于单片机的电梯控制系统设计 PAGE 本科毕业设计 基于单片机的电梯控制系统设计 摘 要 本文主要介绍了基于单片机的电梯控制系统，在本次设计中我们模拟了三层楼层的电梯的运行以及其中相应的逻辑关系。在没有使用到真正的电梯箱和电机的情况下，我们使用LED指示灯以及电梯内部和电梯外部各个楼层的按键来模拟电梯接收到按键信号后的运行情况。 电梯控制系统的硬件部分主要由单片机最小系统模块、LED显示模块、按键中断请求模块等3部分组成。该系统采用单片机（89C52）作为控制核心，根据各楼层按键检测结果来控制电梯并实现相应的操作。软件部分使用C语言编程，程序部分由主程序、判断电梯运行方向子程序、电梯运行子程序和到达目的地操作子程序等4部分组成。硬件电路的设计简单可靠，结合软件，基本实现了三层楼层的电梯运行的模拟。 关键词:89C52 电梯控制系统 C语言 Design of Elevator Control System Based on MCU Zhan Dongzhe (College of Engineering, South China Agricultural University, Guangzhou 510642, China) Abstract: This text primarily introduced Elevator control system that based on MCU (micro control unit) ,the design we simulate the operation of the elevator of the three floors and the corresponding logical relationship. without using the real elevator car and motor, we describes the elevator control system based on single chip, we use a LED indicator, and buttons inside the elevator and the elevator the various floors of the external button to simulate the elevator to run after the key signal is received. The hardware portion of the elevator control system mainly by the smallest single-chip system module, LED display module, key interrupt request module. The system uses a microcontroller (89C52) as the control, to control the elevator and the appropriate action in accordance with the key test results of each floor. Some use of C language software programming , part of the program by the main program to determine the elevator running direction of the subroutine, elevator operation subroutine and reach the destination operation subroutine parts. The design of the hardware circuit is simple and reliable, combined with software, the basic realization of the three-floor elevator running simulation.
