But on one hand announcing the stops manually by the driver will increase the driver’s labor intensity and on the other hand because of the driver’s wrong announce or failing to announce it may cause passengers to leave by mistake or failing to leave . The phenomenon inferred above may run a negative influence on the public transit greatly and can cause a lot of unnecessary influence on the passengers. For this reason it is essential to study the busstop autoannounce system. The main content researched in this thesis is the busstop autoannounce system based on the wireless transceiver module .This system announces the stop while the bus gets to the station in 10 to 20 meters and it can reveals the serial number and name of stop with LCD when a bus gets to the master station it can send the information of its arrival to the master station which can help the master station to plan a it remends MCSC51 single chipmicroputer used to control this system wireless transceiver module used to receive and send information of announcing knowledge of ISD1420 pronunciation chip the manual keyboard and LCD used for announcing etc. In the end it summarizes this system briefly and put forward the future developments of bus system.
