When the bus is scheduled to arrive at the location, the automatic station report functions 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.
