Automatic shuttling of metro train

This project is designed to demonstrate the technology used in metro train movement which are used in most of the developed countries. This train is equipped with a microcontroller that enables the automatic running of the train from one station to another. This proposed system is an autonomous train and it eliminates the need of any driver. Thus, any human error is ruled out. In this project microcontroller from 8051 family has been used as CPU. Whenever the train arrives at the station it stops automatically. Then the door is opens automatically so that the passengers can go inside the train. The door then closes after a prescribed time set in the controller by the program. The door closes when it reaches maximum time allotted for the door to remain open. The movement of the train is controlled by a motor driver IC which uses the concept of H-bridge operation is interfaced to the microcontroller. The train incorporates a LED to alert the passengers before closing the door and also warn them before staring. As the train reaches the destination the process repeats thus achieving the desired operation. Further the project is enhanced by making this system more advanced by displaying the status of the train over an LCD screen for the convenience of the passengers. The status of the train consists of the parameters like, expected arrival and departure time etc. The system also includes new concept of an emergency response switch enchanced with the “GSM calling module” system which could be used by the passengers in case of any emergency during the journey. Also, The train is equipped with the “Anticollision” feature in whichit will stop automatically if there is any obstacle in its course. This is achieved by using an IR sensor as an obstacle avoidance system.
