| Abstract: | We design a encoding system that can transmit DBPL signals to transponders by using field programmable gate array(FPGA),technology,which consists of serial communication module,UART serial transceiver module,DDS and PLL module,pulse coding module,amplified synthesis circuit and other components.A simulation test shown that this system can simulate railway LEU and realize the coding of DBPL signal in transponder's messages,which can serve as a convenient test training tool for the preparation of transponder messages in railway colleges. |
