An intersection where a railway line crosses a road/highway at the same level is known as “Level Crossing”. Level crossings present a significant risk of collisions between trains and road vehicles. In Bangladesh, the crossing gate is still operated manually by a gatekeeper after receiving the information about the train's arrival that is more risky. So the train accidents at the level crossing are becoming more and more usual. That’s why the topic has been chosen. Now-adays, every system is automated in order to face new challenges.
Automated systems that have less manual operation are flexible, reliable and accurate. Due to these demands every field prefer automated control systems specially in the field of electronics where automated systems are giving good result. Microcontroller is one of the major devices in the field of electronics. While using microcontroller has become very much popular for its wide application field and user adaptability, microcontroller is used in many major areas. Due to this I have tried to design this intelligent system for train engine with automatic gate controlling to avoid accidents at level crossings based on microcontroller.
Actually the main objective of designing this intelligent system is to avoid accidents at level crossing and save human lives as well as valuable property of a country. In this system there are mainly two units: Signal Pole Unit and Train Unit. Signal Pole Unit includes some major equipment like IR Sensor, Buzzer, LEDs, RF Transmitter, Encoder, DC Motor, Motor Driver, Relays. Train Unit also includes some major equipment like RF Receiver, Decoder, DC Motor, Motor Driver, Relays.
Advantages
Automatic operation
Prevent accidents
Safety to the peoples
Fault analyze is easy
Cost effective
Greater accuracy
Low power consumption
Easy installation
No wastage of man-power
Disadvantages
Every train should be provided with RF technology
Need to be installed in large numbers
Applications
This design can be implemented together in the train engine as well as at level crossing to avoid the accidents up to the maximum extent.
Conclusion
From the above discussion and information of this system, it is clear that the system is highly reliable, effective and economical at dense traffic area, suburban area and the route where frequency of trains is more. As the system is completely automated, it avoids manual errors and thus provides ultimate safety to road users. By this mechanism, presence of a gatekeeper is not necessary and automatic operation of the gate through the motor action is achieved. If there is any difficulty then train will stop at few distances from the level crossing. I believe that, designed Intelligent Train Engine can make a positive contribution in our country. So Bangladesh Railway (BR) should take immediate step to implement intelligent system in the railway sector to minimize the chance of accident and to ensure safety to the peoples
