In This Project
We try to make prototype for these type of Metro Trains.
We use 8051 as CPU.
The motion of Train is controlled by a Stepper Motor.
LCD Display of 2*16 characters is used for displaying messages in the train.
The stoppage time at a station is taken to be 3 seconds.
The time taken by train between two consecutive stations is taken as 6 seconds.
WHY WE USE ULN 2003?
Microcontroller pins lack sufficient current to drive the relay. They can provide a maximum of 1-2mA current. While the stepper motor’s coil needs around 10mA to be energized. For this reason, we place a driver so that stepper motor can work efficiently.
FUTURE SCOPE OF THIS PROJECT
This Project is useful in developing countries & this project has a bright future as it is being used in countries like Germany, France & Japan. This project helps us to control train without a driver and the stations are shown on the LCD so the passenger doesn’t have any type of difficulty. This project will lead to increase in technological trends & this will help the people in many ways.
