Robust Railway Crack Detection Scheme (RRCDS)

Introduction

• The project aims in designing robust railway crack detection scheme (RRCDS) using Laser which avoids the train accidents. And also capable of controlling the whole system by using the GPS based GSM modem.

PRINCIPLE OF OPERATION

• The basic principle of operation is, when laser pointer is placed at one side of the railway track and sensor on the other side, whenever laser light falls on the sensor then it indicates that the track is disjoint and by which further operations will takes place.

Components• Laser pointer and sensor-2• Robotic wheels • Robotic motor Dc• Robotic Arm• Power supply batteries -3v,9v,12v• IC7805• ILQ74 optoisolator• L293 h bridge• Max 232 IC• Microcontroller –pic18f452• Gsm module• Gps module• Resistors,capacitors• Crystal 10Mhz

LASER POINTER AND SENSOR

• Laser pointer is the laser source which emits the laser light and sensor is “L14F1”

GPS AND GSM

• GPS is the Global Positioning System , which help us to track the particular location on the earth

• GSM is the Global System for Mobile communication, which help us to deal with the phone services like calls , messages, etc

Important IC’s

• L293 h-bridge IC: It is used to drive the motor which is connected to it.

• ILQ74 IC: It is used to separate motor and microcontroller to rid of any electric shock ,protection to microcontroller.

• Max 232: It is used to convert rs232 to ttl logic.

MOTORS

• Motors are used for the mechanical rotation of wheels of the robot.

Necessity

• Railway accidents are increasing year by year, there are 797 accidents occurred in the last 10 years and about 454 lost their life.

• Our project will help to prevent most number of railway accidents.

APPLICATION

• The most powerful application of this project is to alert the government by tracing the disjoint location and by which proper steps can be taken further more ..

Conclusion

Hence I conclude that the project Robust Railway Crack Detection Scheme (RRCDS) is sophisticated methodology to detect and alerts the disjoints of railway tracks and to prevent railway accident.
