编号: 本科毕业论文(设计) 题目:基于 AT89C51 的公交车语音报站器的设计 系 (院):信息工程学院 专 业:通信工程 摘 要 公交车已经成为一般工薪族和学生族出门必须的交通工具,目前公交车上采用 的公交报站系统具有语音和显示报站的基本功能, 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,造成乘客误下或 漏下,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,研究公交车自动报站系统是非常必要的。 本课题主要研究的是基于 AT89C51的公交车自动报站系统,该系统在公交车到 站前语音报站,并且有 LED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,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 LED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; LED I Abstract The public transportation has already became the general wage race and the student race went out must the transportation vehicle, at present on the public transportation uses the public transportation newspaper station system had the basic function which the pronunciation and the demonstration newspaper stood, but because the newspaper stood time used the driver manual cut, on the one hand increased drivers labor intensity, on the other hand because drivers misinformation or failed to report, created the passenger by mistake under or the mild chronic bloody vaginal discharge, has had the very greatly negative influence regarding the public transportation operation, could have very many nonessential influences to the passenger.Therefore,studies the public transportation automatic newspaper station system is extremely essential. This topic main research is based on at89C51 public transportation automatic newspaper statio
