|In this project we show that how we use automation system in train ,
By using this system in any vehicle , it is possible to move the vehicle on predefined track with auto stop I provision. In this project we try to stop the train on minimum five stoppage and give a auto reverse logic for then end of path. By adding this logic with train we move the train for long time with out changing the direction,
In this project we use ic 89c51 microcontroller to control all the logic , movement of vehicle, stoppage of vehicle, and reverse action of vehicle with the help of this microcontroller and different sensor’s.
In this project we use dc gear motor to run the vehicle to and fro automatically. We use slow speed dc motor to increase the torque and slow the speed of vehicle, this DC motor is run by a 5 volt to 12 volt dc voltage. We use additional gear box if we want to slow down the speed.
In this project we use infra red sensor to stop the train and infra red sensor to reverse and again forward the train.
So we use three pair of infra red reflective sensor in this project. One at the bottom of this train, second in the front of this train and third at the reverse of this train.
By using three sensor we not only stop the train but also reverse the train.
As per logic in concern we use three inputs in this project, one from the ground sensor and two from the front and back sensor.. Three input and one motor.
Here in this project we use dc motor to run the vehicle, for the dc motor we use H bridge circuit in this project. H bridge circuit not only drive a sufficient power to dc motor but also provide a forward and reverse logic to the motor .
