STC89C51单片机电梯控制系统设计+电路图

摘要这篇论文的中心就是围绕着如何构建一个电梯模拟系统模拟电梯运行而展开的，而这个电梯模拟系统的心脏就是单片机，不仅仅是心脏还是大脑，是能让模拟系统从实物上实现的基础，并且出于功耗、实用性以及性价比，我选取了 STC89C51 芯片作为电梯模拟运行控制系统的主体，再用 C 语言进行程序编程，才能让系统实现各种理想中的功能。从这个电梯模拟运行系统的功能上来说，几个开关作为模拟中的电梯按键，发光二极管作为每个楼层的指示灯，还有几个发光二极管构成的箭头标志，作为一个能够表示运行状态的符号，当然，真实的电梯也少不了声音提醒，所以加入了一个蜂鸣器，当电梯到达指定位置的时候，蜂鸣器就会发出声音进行提醒。在整个系统即将完成之前，我最后还加入了步进电机，更加具体化的模拟出电梯真实的运行方案，让整个系统的实用性变的更强。73927

Elevator simulation system

Abstract The center of this thesis is based on how to build an elevator simulation system to simulate the elevator operation, and the elevator simulation system of the heart is the microcontroller。 Not only is the heart or brain is can let the system simulation from the real implementation based, and out of power, practicality and price, I have selected the STC89C51 chip as the elevator simulation operation control system of main body, using C programming language, in order to make the system realize the function of ideals。 From the elevator simulation system operation function, several switch as the simulation of elevator buttons, a light emitting diode as the indicator of each floor, there are several light emitting diode to constitute the arrow symbol, as a can represent the running state of the symbols, of course, the real elevator less not voice remind, so I joined the a buzzer, when the elevator arrived at the specified location, buzzer will sound to remind。 Before the whole system is about to be completed, I finally joined the stepper motor, more specific simulation of the elevator to the actual operation of the program, so that the whole system is more practical。
