The project aims to enhance the accessibility and safety of railway platforms for elders through the implementation of a movable and flexible platform system. The main controlling device of the whole system is raspberry pi, These IR sensors, limit switches, are interfaced to the microcontroller. And that micro controller is interfaced with raspberry pi, IR sensors input will help the microcontroller to assess the train arrival and departure conditions. Raspberry Pi can serve as the central control unit for the platform, managing the operation of servo motors, APR33A3, SD cards and other components When there is no train on the tracks, the microcontroller will move the platforms closely. When the train arrival detected by sensor then the microcontroller moves the platform in opposite direction and at that time the system sends the announcement through the voice module using speaker. Limit switches help the microcontroller to access the platform movement.        

The main objective of this project is:        

• To create a railway platform that is easily accessible for elders and individuals with mobility issues, ensuring they can board and disembark from trains safely and comfortably.
• To showcase the integration of various technologies, such as IR sensors, servo motors, and voice modules, to create a more modern and technologically advanced railway platform.
• A motor with a driver will control the platform's movement, while servo motors will adjust the platform's height and deploy stairs for easy access.

             

The major building blocks of this project are:  

• Regulated Power Supply.
• PIC Microcontroller.
• Limit switches.
• IR sensors.
• APR33A3 voice module.
