摘要：本设计以单片机为核心，采纳主从双 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。在此根底上，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ABSTRACTThis design take the monolithic integrated circuit as a core, uses main from the double MCU structure, takes the direct acting by the bi-color LED photo tube arrow and about the corner instructed, instructed by the LED nixietube as the countdown, takes the pedestrian general instruction by the bi-color LED lattice, realizes the special purpose vehicle examination by the digital coding wireless mode of transmission, has completed topic request all functions. Based on this, we additionally built the high resolution (320×240) large screen LCD real time display system each condition, simultaneously show date and time; Additionally built the pedestrian to pass through also matches by the image animation and the warm voice prompt; Additionally built has been possible to establish the branch separately according to the traffic congestion situation and the inferior yang or male principle general time, and carried on the optimization design to the system mechanism, the integrity has been good, user-friendly was strong, the reliability was high. Key words: Double MCU Wireless transmission Bi-color LED lattice Optimization design 目 录摘要...........................................................................2引 言............................................
