摘要：本设计以单片机为核心，采用主从双MCU结构，以双色LED发光管箭头作为直行和左右拐弯指示，以LED数码管作为倒计时指示，以双色LED点阵作为行人通行的指示，以数字编码无线传输模式实现特种车辆检测，完成了题目要求的所有功能。在此基础上，我们增设了高分辨率（320×240）大屏幕LCD实时显示系统各种状态，同时显示日期和时间；增设了行人通行还配以形象的动画和温馨的语音提示；增设了可根据交通拥挤情况分别设置主干道和次干道的通行时间，并对系统机械结构进行了优化设计，整体性好，人性化强、可靠性高。关键字：双MCU无线传输双色LED点阵优化设计ABSTRACTThisdesigntakethemonolithicintegratedcircuitasacore,usesmainfromthedoubleMCUstructure,takesthedirectactingbythebi-colorLEDphototubearrowandaboutthecornerinstructed,instructedbytheLEDnixietubeasthecountdown,takesthepedestriangeneralinstructionbythebi-colorLEDlattice,realizesthespecialpurposevehicleexaminationbythedigitalcodingwirelessmodeoftransmission,hascompletedtopicrequestallfunctions.Basedonthis,weadditionallybuiltthehighresolution(320×240)largescreenLCDrealtimedisplaysystemeachcondition,simultaneouslyshowdateandtime;Additionallybuiltthepedestriantopassthroughalsomatchesbytheimageanimationandthewarmvoiceprompt;Additionallybuilthasbeenpossibletoestablishthebranchseparatelyaccordingtothetrafficcongestionsituationandtheinferioryangormaleprinciplegeneraltime,andcarriedontheoptimizationdesigntothesystemmechanism,theintegrityhasbeengood,user-friendlywasstrong,thereliabilitywashigh.Keywords:DoubleMCUWirelesstransmissionBi-colorLEDlatticeOptimizationdesign目录摘要...........................................................................2引言........................................................................5第1章方案设计与论证........................................................61.1总体方案设计与比较....................................................6第2章系统硬件设计..........................................................82.1总体设计..............................................................82.2各功能模块硬件设计及实现..............................................92.2.1交通灯四种通行模式及行车方向指示...................................92.2.2行人通行指示及其实现..............................................112.2.3特种车检测及其实现................................................132.2.4键盘与状态显示及其实现............................................132.2.5语音提示及其实现.................................................152.2.6主次干道单独时间设置功能.........................................162.2.7紧急情况处理功能及其实现.........................................162.2.8倒计时计数功能及其实现...........................................162.2.9日历及时间显示功能及其实现.......................................16第3章系统软件设计.........................................................173.1软件总体流程图.......................................................173.2软件主要子程序流程...................................................183.2.1紧急状态子程序....................................................183.2.2设置状态子程序...................................................183.2.3键盘模块程序流程..................................................19第4章系统调试与测试结果分析..............................................204.1系统操作说明.........................................................204.2调试........................................................
