Abstract :
This project is aimed to design a system to develop an automatic unmanned railway gate by using GSM technology.
A GSM modem provides the communication interface. It transports device protocols transparently over the network through a serial interface. A GSM modem is a wireless modem that works with a GSM wireless network. This GSM Modem can accept any GSM network operator SIM card and act just like a mobile phone with its own unique phone number. Advantage of using this modem will be that you can use its RS232 port to communicate and develop embedded applications. Applications like SMS Control, data transfer, remote control and logging can be developed easily. The modem can either be connected to PC serial port directly or to any microcontroller.
Railways, being the cheapest mode of transportation are preferred over all the other means. When we go through the daily news papers, we come across many railway accidents occurring at unmanned railway crossings. This is mainly due to the carelessness in manual operations or lack of workers. In order to overcome these dangerous problems we in this project came up with a solution for the same. Using simple electronic components and a wireless communication technique we have tried to automate the control of railway gates. The main aim of this project is automating the unmanned railway gate i.e. the gate is closed automatically whenever the train arrives and gate is opened after the train leaves the railway-road crossing. The arrival of train in either direction can be identified using this project. Use of embedded
technology makes this closed loop feedback control system efficient and reliable. AT89C51 microcontroller is the heart of the circuit as it controls all the functions.
