Design of railway signaling system using IR sensor as train detection

Abstract

In this research would try to give contribution for researchers or academics about simulation of the railway signaling system. The model of railway system was built using miniature of track and train model. Small LED was used as a lamp signal. Point machine was moved by servo motor controlled by Arduino Nano. The last, track circuit was replaced by proximity sensor using IR transceiver. The result showed that the simulation could do some basic task which is occurred in railway signaling system. The design of system was created by FSM (Finite State Machine) method which would be implemented in PLC (Programmable Logic Controller). It consists of state diagram, declaration of inputs and outputs, generated logic equation, and finally is the written code in ladder logic diagram. Set route test also has been tried successfully and the lamp signal showed the color aspect correctly.
