论文题目：基于VHDL的电梯控制系统设计
专业： 电气工程及其自动化
摘 要
电梯是标志现代物质文明的垂直运输工具，是机—电一体化的复杂运输设备。而电梯的核心是电梯控制器。对于电梯的控制，传统的方法是使用继电器—接触器控制系统进行控制，随着技术的不断发展， 采用硬件描述语言VHL来完成电梯控制器的设计, 是设计智能化的标志。
本文结合EDA自上而下的设计特点分析了电梯控制系统的工作原理，给出了电梯控制系统的设计框图，并用VHDL语言描述出了整个系统，最后用QuartusⅡ软件进行了仿真，分析了仿真结果，进行了总结。
本文结构主要分成四大部分：
第一章介绍了电梯控制系统的发展情况及发展趋势，交代了课题的研究背景，并对要完成的工作做了介绍；
第二章介绍了EDA技术的主要特点，并对VHDL语言的功能及其结构进行了描述，并着重介绍了状态机的含义；
第三章以VHDL语言作为描述工具，对四层电梯的结构进行分析，给出了电梯控制器的设计流程和状态机描述；
第四章用QuartusⅡ软件对程序进行了仿真，并对仿真结果进行了说明和分析，并进行总结。
关键字：电梯控制器，EDA，VHDL状态机

Abstract
Elevator is the symbol of modern vertical transport of material is machine - the complexity of transport equipment, electrical integration. The elevator is the core of elevator controller. For the elevator control, the traditional approach is to use relay - contactor control system to control, as technology continues to develop, using hardware description language VHL to complete the elevator controller design, is a sign of intelligent design.
This paper EDA Design features of a top-down elevator control system working principle of the elevator control system block diagram and describe the use of VHDL, the whole system, and finally with Quartus Ⅱ simulation software to analyze the simulation results , is summarized. This structure is divided into four parts:
The first chapter describes the elevator control system development and trends, explain the topic of the research background, and to complete the work have been described;
Chapter II describes the main features of EDA technologies, and VHDL language features and structure are described, with an emphasis on the meaning of the state machine;
The third chapter describes VHDL language as a tool for analyzing the structure of four elevators, the elevator controller is given the design process and the state machine description;
Chapter IV with Quartus Ⅱ software process simulation, and simulation results are described and analyzed and summarized.
Keywords: elevator controller, EDA, VHDL State Machine
