成都理工大学工程技术学院毕业论文步行街道自助式交通灯控制器的设计作者姓名：专业名称：电气工程及自动化指导教师：步行街道自助式交通灯控制器的设计-I-摘要随着社会经济的发展，城市交通问题越来越引起人们的关注。人、车、路三者关系的协调，已成为交通管理部门需要解决的重要问题之一。城市交通控制系统是用于城市交通数据监测、交通信号灯控制与交通疏导的计算机综合管理系统，它是现代城市交通监控指挥系统中最重要的组成部分。所以，如何采用合适的控制方法，最大限度利用好耗费巨资修建的城市双干线道路，越来越成为交通运输管理部门亟待解决的主要问题。论文研究交通灯控制器的设计与实现，并利用EDA技术等知识设计了一套自助式交通灯控制器的方案。自助式交通灯控制器主要由计数电路、控制电路、信号灯转换器、脉冲信号发生器组成。通过采用数字电路自助式对交通灯控制器的设计，提出使自助式交通灯控制器用数字信号自动控制双干线路口两组红、黄、绿交通灯的状态转换的新方法，指挥各种车辆和行人安全通行，实现双干线路口交通管理的自动化。EDA技术在自动化控制实现方面有着诸多优势，值得进一步学习和研究。关键词：交通控制系统EDA自助式交通灯控制器自动化步行街道自助式交通灯控制器的设计-II-AbstractAlongwithsocialeconomy’sdevelpoment,themunicipaltransportationquestionarousespeople’sinterestmoreandmore.Theperson,thevechicle,roadthreere;ations’coordinated,havebecomeonewhichofimportantquestionsthetrafficcontroldepartmentneedstosolve.Themunicipaltransportationcontrolsystemisusesinthemunicipaltransportationcontrolsystemisusesinthemunicipaltransportationdatamonitor,thestreet-trafficcontrollightscontrolandthetransportationunblockingcomputerintegratedmanagementsystem,itisinthemodernmunicipaltransportationmonitoringcommandsystemthemostimportantconstituent.Therefore,howtousetheappropriatecontrolmethod,maximumlimitusesthegoodconsumptionlargeamountofmoneyconstructionthecitydoublemainroad,becomesthesubjectmatterwhichmoreandmoretrafficmanagementdepartmenturgentlyawaitstobesolved.thepaperresearchtrafficlightcontroller'sdesignwithrealizes,andusingknowledgeandsoonEDAtechnologyhasdesignedasetofself-servicetypetrafficlightcontroller'splan.Theself-servicetypetrafficlightcontrollermainlybythecountingcircuit,thecontrolcircuit,thesignallightswitch,thesignalimpulsegeneratoriscomposed.Throughusesthedigitalcircuitself-servicetypetothetrafficlightcontroller'sdesign,proposedthatcausestheself-servicetypetrafficlightcontrollerwiththedigitalsignalautomaticcontroldoubleskeletonlinestreetintersectiontwogroupsred,yellow,thegreentrafficlight'sphasetransitionnewmethod,directseachkindofvehiclesandthepedestrianpassesthroughsafely,realizesthedoubleskeletonlinestreetintersectiontrafficcontrolautomation.TheEDAtechnologyrealizestheaspectintheautomatedcontroltohavemanysuperiority,isworthfurtherstudyingandstudying.Keywords:trafficcontrolsystemself-servicetrafficlights,EDA,automationcontroller步行街道自助式交通灯控制器的设计-III-目录摘要............................................................................................................IAbstract..................................................................................................II目录.........................................................................................................III前言...........................................................................................................11EDA技术................................................................................................41.1EDA技术的发展回顾.................................................................41.2EDA技术的构成.........................................................................51.3EDA技术实现目标.....................................................................61.3.1超大规模可编程逻辑器件...................................................61.3.2半定制或全定制ASIC.........................................................61.3.3混合ASIC.............................................................................81.4硬件描述语言VHDL..................................................................91.5基于VHDL的自顶向下设计方法..........................................101.6EDA与传统电子设计方法的比较...........................................121.6.1传统的电子设计方法.........................................................121.6.2现代电子设计方法———电子设计自动化.....................131.6.3EDA与传统电子设计方法的比较.....................................131.6.4EDA常用的基于VHDL的设计方法以及特点................142EDA设计流程及其工具......................................................................172.1FPGA/CPLD设计流程.............................................................172.2FPGA/CPLD区别.....................................................................202.3ASIC及其设计流程..................................................................242.4EDA常用工具...........................................................................283VHDL设计............................................................................................313.1MAX+plusⅡ概述....................................................................313.2VHDL文本输入设计方法初步................................................34步行街道自助式交通灯控制器的设计-IV-3.2.1将当前设计设定为工程...................................................363.2.2选择VHDL文本编译版本号和排错..............................383.2.3时序仿真.............................................................................403.2.4硬件测试.............................................................................453.2.5设计流程归纳...................................................................483.2.6MAX+plusII在Windows2000上的安装设置..................483.3原理图方式设计初步...............................................................493.3.1为本项工程设计建立文件夹..............................................493.3.2输入设计项目和存盘.........................................
