INTRODUCTION
Indian railways is the fourth largest railway network in the world which runs around 11,000 trains every day, of which 7,000 are passenger trains transporting over 6 billion passengers annually. Safety measures employed now is not effective especially in the method of crack detection of rails.
Our project “SOLAR AUTOMATIC RAILWAY TRACK CRACK DETECTING VEHICLE” is a concept of detection of cracks in railway tracks automatically and prompts to adopt the required steps to avoid accidents.
RAILWAY ACCIDENT
Railway Accidents occur due to the following reasons:-
The unmanned level crossing
Signal Failure
Human error
Crack in the railway track
Any big object in the track
SENSOR
The sensor used in our project is IR sensor. They use infrared light to sense the crack in the railway track automatically. Once the crack is detected, the signal is sent to the FM transmitter unit.
FM TRANSMITTER
FM Transmitter unit is used to activate the receiver unit when the signal is received from IR sensors.
FM RECEIVER
The transmitted signal is received by the receiving aerial at the nearest railway station. This signal turns the relay circuit ON which gives an alarm about the crack in the track.
TRANSMITTER CIRCUIT DESCRIPTION
The transmitter is made to activate with the supply from a 9volt battery. When IR sensor giving the crack detection signals the 9Volt is supplied to the Frequency modulator. The frequency modulator modulates the base hand signal by using a proper carrier frequency. The output of the modulator is given to a high power amplifier to raise the modulated signal. This modulated signal is then fed to the transmitting antenna.
WORKING PRINCIPLE
In our project, there are two set of IR sensor units are used to fit the two sides of the vehicle. This unit is used to activate/deactivate FM transmitter unit when there is any cracks in there path.
The IR transmitter and IR receiver circuit is used to sense the cracks. It is fixed to the front sides of the vehicle with a suitable arrangement
CONCLUSION
This project work has provided us an excellent opportunity and experience, to use our limited knowledge. We gained a lot of practical knowledge regarding, planning, purchasing, assembling and machining while doing this project work.
We have completed the project work with the limited time successfully. The AUTOMATIC RAILWAY TRACK CRACK DETECTING VEHICLE is working with satisfactory conditions. We are able to understand the difficulties in maintaining the tolerances and also quality. We have done to our ability and skill making maximum use of available facilities.
