Keywords : Allen Bradley PLC, Railway Gate, Obstacle Detector Abstract :The existing conventional railway crossing gate control systems are being operated manually. Thus, many accidents are being occurred due to the carelessness in manual operations or lack of workers. To avoid such accidents the proposed project will analyze few vulnerable areas of accidents and help to find out the possible way to reduce the number of accidents. This paper provides an automatic railway crossing gate replacing the gates operated by the workers. This project helps to reduce the time for which the gate is being kept closed and provide safety to the road users by reducing the accidents. In this work, an automatic railway crossing gate control system has been developed using a Programmable Logic Controller (PLC). For this purpose, we used Allen- Bradley Micrologix PLC and Rockwell software for PLC programming. Signaling light models are implemented using several red, green and yellow Light Emitting Diodes (LEDs); and railway gates are opened using DC motors with gear trains that are connected to the output ports of the PLC. For energizing different parts of the system and DC motors, separate DC power supplies have been designed.
