1、编号:摘要公交车己经成为一般工薪族和学生族出门必须的交通工具,FI前公交车上采用的公交报站系统具有语音和显示报站的棊本功能,但由于报站时采用司机手动切换,一方面增加了司机的劳动强度,另一方面由于司机的误报或漏报,造成乘客误不或漏不,对于公交运营产生了很大负面影响,更会对乘客造成很多不必要的影响。为此,研宄公交车自动报站系统是非常必要的。本课题主要研宄的是棊于AT89C51的公交车动报站系统,该系统在公交车到站前语音报站,并且有LH)数码管显示,到总站时公交车可向总站发送到站信息,方便总站安排公交车次。本课题要求设计一公交车自动报站系统,
2、以实现公交车的语音自动报站,即在进站、出站时候自动播报语音提示信息及服务用语,同时利用LH)点阵电路进行汉字显示。本设计要求利用AT89C51作为主控芯片完成主控电路的设计,辅助电路要求包括语音电路、汉字点阵显示电路、电源电路等。公交车报站系统主要由四个部分组成,即主控电路、脉冲检测电路、语音电路以及LED点阵汉字显示电路。关键词:自动报站;89C51单片机;语音芯片;LEDAbstractThepublictransportationhasalreadybecamethegeneralwageraceandthestudentrace
