摘要：本文介绍的是8层电梯模拟控制系统，采用以Atmel公司生产的STC89C52RC芯片来进行对8层电梯的模拟控制，并阐述了MCU进行C语言编程来实现8层电梯模拟控制的设计方案。MCU编程有很高的移植性，可以实现许多的功能，可以缩短整个电梯模拟控制系统的研发周期，来提高运行的效率，更加利于产品的开发，同时电路的设计，将电梯控制系统体积做到更小，成本更低。目前电梯的基本功能都在本次设计的8层模拟电梯控制系统中体现，用户通过选择不同的按键到达不同的楼层，采用一位共阴数码管实时地显示出相应的楼层数，电梯上下运行的方向是由12个LED灯组成的箭头来指示的。而且把大学所学的专业知识运用到了本次毕业设计中，如数字电路和模拟电路等。

Design of simulated elevator based on single chip microcomputer

Abstract：This article describes the 8-story elevator simulation control system, the use of Atmel's STC89C52RC chip to simulate the 8-story elevator control, and describes the MCU C language programming to achieve 8-story elevator simulation control design. MCU programming has a high degree of portability, can achieve many functions, can shorten the entire elevator analog control system development cycle, to improve the efficiency of the operation, more conducive to product development, the circuit design, the elevator control system volume Smaller, lower cost. At present, the basic functions of elevators are embodied in the 8-layer analog elevator control system designed this time. Users select different buttons to reach different floors, and one common-yang digital tube displays the corresponding floor number in real time. The elevator runs up and down. The direction is indicated by an arrow consisting of 12 LED lights. In addition, the university has applied its professional knowledge to this graduation project, such as digital circuits and analog circuits.
