Logic controller for railway locomotive

The logic controller for railway locomotive consists of main control board, input board, output board and power supply board, and features the bi-directional CAN bus communication among the control board, the input board and the output board, and the MOS FET driving between the output board and the electric device of the locomotive to be controlled. The present invention adopts embedded monochip computer system, CAN bus technology, and cured combination logic software in PLC logic ladder diagram structure easy to read and understand. Adopting logic control unit can simplify the design, production and debugging of locomotive control circuit, and raise the reliability of the control system. In addition, the microcomputer and electronic control system has vibration resistance obviously superior to traditional relay contact control system.
