通信工程毕业论文--基于AT89C51单片机的公交车语音报站器的设计.docVIP

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。本主要研究的是基于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自动报站89C51单片机语音芯片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 station system front, this system stations of arrival the pronunciation newspaper station in the public transportation, and has the LED nixietube to demonstrate, to main terminal when the public transportation may station of arrival the information to the main terminal transmission, convenient main terminal arrangement public transportation coach number.This topic request designs a public transportation automatic newspaper station system, realizes the public transportation pronunciation automatic newspaper station, namely is entering the station, outputting time disseminates news the voice prompt information and the service language automatically, simultaneously carries on the Chinese character demonstration using the LED lattice electric circuit.This design request using AT89C51 took the master
