The balise is a device for the railroad signal control systems, which is installed between both rail. The balise sends fixed or variable data, named telegram, to the train with wireless method. The telegram includes the position information, the movable distance under the signal status, the gradient, the speed, the temporary speed limit, etc. This research is on a design of the DBPL encoder for the balise. Normally the DBPL encoder for the balise is with the ASIC or FPGA technology. In this research, the DBPL encoder is designed with commercial low power operable micro-controller. The firmware(logic level encode) and the SPI Bus function block(physical level output) of the micro-controller are used for the DBPL encode. Under the european standard, the required working speed of the DBPL encoder is 564.48Kbps. The DBPL encoder of this research is tested under the speed of 564.48Kbps, and it worked properly.
