Therefore, a good traffic light control system, will bring technical innovations for road congestion, illegal control, etc. With the rapid development of large scale integrated circuits and puter technology and the extensive use of intelligent devices in the control of artificial intelligence technology, intelligent devices have gotten great progress and bee the mainstream of the development of modern science . This paper describes the system design of traffic lights . Traditional traffic light control system is mostly achieved by a single chip or PLC, this paper introduces a scheme of the design of traffic signal systems based on EDA technology . An important feature of EDA technology is the use of hardware description language (HDL) to plete the system design documents, the experiment applied VHDL digital circuit reduces the difficulty of digital system design, which has been widely adopted by the designers of electronic area. This design puts forward a method of hardware implementation for traffic lights system based on VHDL language to resolve the design problem of traffic signal controller . Each module is given VHDL program by analyzing the structure of the system and using a hierarchical design method, and it applies Max Plus Ⅱ on the simulation of applications , and the corresponding simulation results are gained. When design the circuit with VHDL, we should be fully aware of the characteristics of VHDL language and optimize the circuit design from the design, the use of statements and methods of description, optimizing circuit design, we can use smaller programmable logic chip, thereby reducing system cost. Design and implementation of traffic light controller with VHDL the system for structural analysis, using topdown hierarchical design method, gives a VHDL program modules, and applications using Quartus II simulation, have e to the corresponding simulation design with VHDL language, should be 西安交通大學城市學院本科生畢業(yè)設計 (論文) fully aware of the features of VHDL language, from the design, use statement, and description of the superior aspects of optimized circuit optimization design of circuits, programmable logic chip can use smaller, thus reducing system costs. Keywords: Traffic light , VHDL language , Simulation 摘要 西安交通大學城市學院本科生畢業(yè)設計 (論文) 目錄 摘 要 ............................................................................................................................ 2 ABSTRACT................................................................................................................... 3 第一章 前言 ................................................................................................................ 8 選題意義 .......................................................................................................... 8 交通燈發(fā)展史及國內外研究現狀 .................................................................. 9 主要研究內容 ................................................................................................11 章節(jié)安排 ........................................................................................................12 第二章 本文 研究平臺 簡介 ...................................................................................... 12 CPLD 復雜可編程邏輯器件 ......................................................................... 13 CPLD 結構及其發(fā)展 ...................................................................................13 CPLD 的特點及其使用 .............................................................................. 13 EPM7128SLC8415 芯片介紹 .................................................................. 14 VHDL 硬件編輯語言 ..................................................................................... 14 VHDL 語言及其發(fā)展 ..................................................................................15 VHDL 語言設計流程 .................................................................................. 15 VHDL 的描述風格 ...................................................................................... 15 選擇 VHDL 硬件描述語言設計的優(yōu)勢 ....................................................17 Quartus Ⅱ 簡介 ............................................................................................... 18 第三章 交通燈系統(tǒng)的設計 ...................................................................................... 20 紅綠燈交通信號系統(tǒng)功能描述 .................................................................... 20 任務和要求 .......................................................................................... 20 設計思想 .............................................................................................. 20 紅綠燈交通信號系統(tǒng)的 VHDL 模塊 .......................................................... 24 控制模塊 .............................................................................................. 24 分頻模塊 .....................................
