Project Summary

In Pakistan, railway gates are generally opened or closed manually by a gate keeper. But some railway crossings are totally unmanned and many railway accidents occur at these unmanned level crossings. The other significant issue confronted by the general population at these unmanned railway gates is the amount of waiting time for which these gates are being shut. Automatic Railway Level Crossing System is simply a system that automatically opens and closes the railway gate upon detecting arrival or departure of the train. Although some electric engineering students have attempted to develop such systems, no efforts have been found from the software engineering side. Therefore, instead of merely developing an electronics system, the proposed system would comprise of both hardware and software components. This is because, modern safety critical systems are becoming software intensive, where software functions are mostly used to control the system. In this regard, the project would follow the complete software life-cycle (i.e., specifying the software requirements and design constraints, component development and testing).

Project Objectives

• To specify the requirements for developing Automatic Railway Level Crossing System.
• To design and develop Automatic Railway Level Crossing System.
• To verify the applicability and effects of the developed Automatic Railway Level Crossing System. 

Project Implementation Method

Automatic Railway Level Crossing System is simply a system that automatically opens and closes the railway gate upon detecting arrival or departure of the train. The proposed system would consists of hardware and software components. The hardware components include recognition module (to recognize the train from certain km from the gate), transmission module (to transmit the signal to the gate upon recognizing the train) and control module (to open and close the gate upon receiving the signals). The recognition hardware (mounted both on the train and the ground) would use RFID technology.

Benefits of the Project

• the proposed system will avoid accidents at railway crossing 
• the proposed system would reduce the amount of time the railway gate is closed
• no personal is needed for the proposed system, as it is automatic
• trains would not have to wait for the level crossing to be closed, thus they can reach on time

Technical Details of Final Deliverable

The recognition module of the proposed system would comprise of transmitting and receiving sections. The transmitting section would be mounted in front of a train, whereas the receiving section would be placed on ground at certain km away from railway gate. Using RFID technology the recognition module would recognize an incoming train (with RF-sensor) and would pass this information using the transmission module to the gate. The received encoded data by RF receiver module is then decoded using a decoder which is then processed by a microcontroller and passed onto a motor driver to close the gate.  Once the control module at the gate realizes an incoming train, it enacts the speaker to alarm the street clients; the status is shown on a screen and starts closing the gate. After the train crosses the gate, the control module stops the alarming speaker and starts opening the entryway. The proposed system uses Arduino as microcontroller for control and several sensors for recognition and data transfer.
