Automatic railway gate control track switching

Railway tracks are one of the major areas where accident takes place everyday and Automatic railway gate control & track switching project is dedicated to stop such accidents on a unattended railway gates. This project gives the brief idea about an automated railway gate opening and closing using DC geared motor. In this project microcontroller, Infrared transmitter-receiver and DC GEARED motor are used. The infrared transmitter-receiver senses the incoming train and sends signals to the microcontroller for closing the railway gate, and when the train crosses the gate, it is automatically opened for providing the free passage to traffic.

Automatic railway gate control and track switching project is made using Atmega8 microcontroller to avoid railway accidents happening at unattended railway gates, if enforced in spirit. This project utilizes 2 powerful IR transmitters and 2 receivers; one try of transmitter and receiver is fastened at up facet (from wherever the train comes) at A level on top of somebody's being in precise alignment and equally the opposite try is fastened at down facet of the train direction. Detector activation time is thus adjusted by conniving the time taken at a definite speed to cross a minimum of one compartment of normal minimum size of the Indian railway and for this project it is 5 seconds.

Sensors are fastened at 1km on each side of the gate. we have a tendency to decision the detector on the train direction as ‘foreside sensor’ and therefore the alternative as ‘aft facet sensor’. Once foreside receiver gets activated, the gate motor is turned on in one direction and therefore the gate is closed and stays closed till the train crosses the gate and reaches aft facet sensors. once aft facet receiver gets activated motor turns in wrong way logic gate opens and motor stops. Buzzer can now sound at the fore facet receiver activation logic gate can shut when five seconds, thus giving time to drivers to clear gate space so as to avoid saddlery between the gates and stop sound when the train has crossed.

The same principle is applied for track switching. Considering a state where local and super fast train are traveling in opposite directions on an equivalent track; the categorical train is allowed to travel on an equivalent track and also the local train needs to put on to the opposite track. 2 sensors square measure placed at the either sides of the junction wherever the track switches. If there’s a train approaching from the opposite aspect, then associated detector placed on that direction gets activated and can send an interrupt to the controller.

Aim of this project is control the unmanned rail gate automatically using embedded platform. Today often we see news papers very often about the railway accidents happening at un-attended railway gates. Present project is designed to avoid such accidents if implemented in spirit.

This project utilizes two powerful IR transmitter and two receivers, one pair of transmitter and receiver is fixed at upside (from the train comes) at a level higher than human being in exact alignment and similarly other pair is fixed at down side of the train direction sensor activation time is so adjusted by calculating the time taken at a certain speed to cross at least one compartment of standard minimum size of the Indian railway, normally 5 seconds.

The sensors are fixed at 1000 meters on both sides of the gate, we call fore side sensor pair for common towards gate train, and aft side sensors for the train just Crosses the gate. When train cross the fore side sensor it gives signal to the gate receiver to close the gate. The buzzer is activated to clear the gate area for drivers about 5 seconds.Gate motor is turned on in one direction and gate is closed, and stay closed till train crosses the gate and reaches aft side sensors when aft side receiver get activated motor turns in opposite direction and gate opens and motor stops.

If there is any problem in the gate means it will operate red signal on both side fro the driver indication. Train arrival and departure sensing can be achieved by means of Relay techniques. When the wheels of the train moves over, both tracks are shorted to ground and this acts as a signal to microcontroller (89C51) indicating train arrival. RED signal appears for the road user, once the train cuts the relay sensor placed before the 5Kms before the gate .A buzzer is made on as a pre cautionary measure for the road users.
