摘 要
单片机即单片微型计算机（Single-Chip Microcomputer ），是集CPU ,RAM ,ROM ,定时，计数和多种接口于一体的微控制器。其中51单片机是各种单片机中最为典型和最有代表性的一种,广泛应用于各个领域。
电梯是集机械原理应用、电气控制技术、微处理器技术、系统工程学等多学科和技术分支于一体的机电设备，它是建筑中的永久垂直交通工具。本论文选择CygnalC8051为核心控制元件，设计了一个十三层电梯系统，采用SA4828芯片做为变频器进行控制转速，采用行程开关控制其开关门，以及8279作为显示电路。使用单片机汇编语言进行编程，实现运送乘客到任一楼层，并且显示电梯的楼层和上下行。单片机在接口性能和计算速度等方面均有资源不足的问题，仍然不能适应较复杂的控制算法和故障诊断等要求。
利用单片机控制电梯有成本低，通用性强，灵活性大及易于实现复杂控制等优点。

Abstract
microcontroller that microcomputer (Single-Chip Microcomputer) gathering CPU, RAM, ROM, the timing, number and variety of interface integrated microcontrollers. 51 various SCM SCM is the most typical and most representative of a widely used in various fields. Elevator is the application of the principle set machinery, electrical control technology, microprocessor technology, systems engineering and other technical disciplines and branches of the integration of mechanical and electrical equipment, which is building a permanent vertical transport. This paper choice CygnalC8051 control of the core components, designed a new 13 storey lift systems, SA4828 chip used as a converter to control speed, using their trip switch control switch doors, and 8279 as the display circuit. Using single-chip assembly language programming, transporting passengers arrived a floor, it also shows the elevator floor and downlink. Microcontroller interface performance and the speed we have see
