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 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 control chip completes the master control electric circuit the design, auxiliary circuit request including pronunciation electric circuit, Chinese character lattice display circuit, power circuit and so on. The public transportatio
