Abstract

Nowadays, it is very often that some portion of the Indian traction system is still suffering from a single line railway transportation. This in turn creates a havoc disturbance in maintaining the proper sequence of traction control system. Also, passengers are taking risk to catch the train which is already in motion but no such action has been taken to eliminate these consequences. It has been found that more or less various works have been done on Automation in Railway Crossing Gate using Microcontroller and IR Sensor. Thus, it is often decided to develop an idea for the Indian traction system to ensure better controlling action by introducing Limit Switches as Tactile Sensors and by introducing HMI using PLC. The purpose here to take control over various controlling domains, including Railway crossing gate are as follows: Track signal, crossing level signal, alarm notification, and platform edge fence. The proper sequencing needs to be operated via a 128 I/O module with 2 KB memory size small PLC kit.

Block Diagram Of Automation System

In Figure 1 a general block diagram is presented. The block diagram is a set of three different blocks. The concerned blocks are inputs, PLC module and outputs. Inputs to the PLC module are fed from limit switches that are pressed by the train flanges and a push switch to be pressed by the console operator. The PLC module then scans the entire rungs of the ladder diagram to initiate the output loads. The output will then actuate as per the supply fed by the concerned bus. Here the outputs are fence motor, crossing gate motor, train signal, crossing gate signal and alarm circuitry.
