Abstract:       

Due to the drastic changes in technology in the last decade, so many advancements were introduced in transport departments. The reservation can be done now through E-Seva centers, internet and even through mobile phones. This GSM based train reservation system is a unique and advanced concept through which we can book the railway tickets through your mobile phone by a simple SMS.

The project is implemented by using AT89S52 MCU GSM is responsible for all the mobile phone services. GSM operates through SMSs and is the link between controller and centralized unit.

 AT89S52 is the heart of the system. Our project aims to implement the train reservation system through mobile phones. GSM modem can be controlled by standard set of AT (Attention) commands. These commands can be used to control majority of the functions of GSM modem. 16X2 LCD is used for displaying the status.

  In this project by sending a simple SMS we can get the status of vacant seats (A/c or non A/c). From the central system we get a reply status of vacant seats on a particular day. After conforming, we can book the ticket by sending a 16 pin credit card number to the reservation system. As a conformation, we can get the M-Ticket (Mobile Ticket) to your mobile phone; just we have to carry the ticket with us for travelling.

This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
