Design of Wireless Intelligent Train Identification System Based on GPS/GPRS

The wireless intelligent train identification system based on embedded system was designed with ARM9 RSIC CPU AT91SAM9260 and Telit GE863-GPS. The embedded system communicates with RFID module and Telit GE-GPS by serial ports. The embedded system communicates with CPS by serial port, Ethernet or GPRS. The real-time of train identification and data transmission was implemented by interrupt produced by pulse of wheel sensor. The flow chart was created according to system work flows. The initial process of wireless module, the collecting process of position information and the connecting process of GPRS were introduced with program.
