In recent years,with sustained economic development of public transport also its higher requirements are put forward.Traditional bus reporter must be manipulated by the driver,considering the safety of public transportation system,there is an urgent need for intelligent,automatic station report system for bus.GPS and GPRS technology for application enable the bus station report system a high degree of integration,changing the traditional manual-announce way,the current way of updating information is solved and the scheduling and other defects can′t be monitored.Combining GPS positioning technology,the bus status information(location,speed,etc.) in real-time acquisition and analysis,when the bus is scheduled to arrive at the location,the automatic station report function is realized.Through the GPRS network,necessary bus status information should be transmitted to the bus monitor dispatching center timely,and then through the center of the operation of PC software,to achieve the function of the monitoring,scheduling and updating information.SD card is used to memorize the information of a number of lines and MP3 audio files,it is facilitated to replace bus lines,and at the same time high-quality voice information play is realized.
