Design of The Bus Voice Announce Station And Display System
Abstract: In view of the shortcoming of present bus voice-announce station system that its information displayed is single and voice is not clear and report about the bus stops is not accurate. This design uses the GPS to determine the vehicle's information timely and the AT89C51 as the control core, ISD4004 voice chip as the output of voice information, LCD AMPIRE128×64 as the output of Chinese characters. By comparing the longitude and latitude information from the GPS with the longitude and latitude information has been set, we can realize the function of automatic voice stops and the information display. This design which can displays and reports the information has been simulated by the Proteus. This design has a good advantage of accurate positioning, clear voice, low power consumption, convenient use. It realizes the automation and intelligence of the bus stops.
Key words: AT89C51; Voice stops; GPS; Automatically
