Automation of Railway Gate Control Using Microcontroller
Atul Kumar Dewangan,Meenu Gupta,Pratibha Patel Lecturer, Kirodimal Govt Polytechnic Raigarh,Chhattisgarh,India Diploma Scholar Kirodimal Govt Polytechnic Raigarh,Chhattisgarh,India Diploma Scholar Kirodimal Govt Polytechnic Raigarh,Chhattisgarh,India Abstract There are many railway crossings which are unmanned due to lack of manpower, needed to fulfill the demands. Hence, many accidents occur at such crossings, since there is no one to take care of the functioning of the railway gate when a train approaches the crossing.The objective of this paper is to manage the control system of railway gate using the microcontroller. The proposed model has been designed using 8052 microcontroller to avoid railway accidents occurring at unattended railway gates, if implemented detection of train approaching the gate can be sensed by means of two sensors placed on either side of the gate. This work utilizes two powerful magnetic sensors; one of these magnetic sensors is fixed at upside (from where the train comes) and similarly the other magnetic sensor is fixed at down side of the train direction. Sensors are fixed on both sides of the gate. We call the sensor along the train direction as ‘foreside sensor’ and the other as ‘after side sensor’. When foreside sensor gets activated, the sensed signal is sent to the microcontroller and the gate motor is turned on in one direction by relay driver and the gate is closed and stays closed until the train crosses the gate and reaches after side sensors. When after side sensor gets activated and the signal about the departure is sent to the microcontroller, motor turns in opposite direction and gate opens and motor stops. type of system with the help of various electrical, electronic and mechanical components.

2. Train Accident
A classification of accidents by their effects (consequences); e.g., head-on collisions, rear-end collisions, derailments. Head on collision; one type of train accident is when two trains collide front face with each other or train colliding on the same track from opposite ends called head on collision. Rear end collision; the other kind is when a train collides into the other that is in front of it, called a rear end collision. Derailments plain track; a train may derail on a simply straight track that may cause the train accident. Curves; derailment of a train is more common when there is a curve on the track causing an accident. Junctions; a train may also get derailed on a junction, which is the place where two tracks converge into one, or one diverges into two. Accident contributors such as train visibility advance signs, active warning, driver behavior, driver distraction and risk taking have been identified as common human factors contributors to vehicle train grade crossing accident [3].Factor includes highway and railway characteristic are contributing factor to accident at RLC [4]. The environmental factors are snow, heavy rain, fog, or blowing snow, which collision the train [5]. The three main factors contributing to accidents at RLC is basic safety engineering studies, human factor, engineering factor, and environment factor [6].The taxonomy of railway intersection accident contributors was created to generate hypotheses and deduction about specific cases and common patterns of accident (See Fig. 1) contributors [7].

1. Introduction
Now a days, India is the country which having world‟s largest railway network. Over hundreds of railways running on track every day. As we know that it is surely impossible to stop, the running train at instant is some critical situation or emergency arises. Train accidents having serious repercussion in terms of loss of human life, injury, damage to Railway property. These consequential train accidents - include Collision, Derailments, Fire in Trains, and...
