CRACK DETECTION IN

RAILWAY TRACK
ABSTRACT
• In India railways transportation service is the cheapest and most convenient mode of passenger
transport as well as for long distance and suburban traffic. Almost 80% of the transport in India is
being carried out by railway network.
• The main cause of the accidents happened in railways are railway track crossing and unidentified
crack in rail tracks. About 60% accidents are happened at railway track crossing and due to crack
in railway tracks resulting in loss of precious life of passengers and loss of economy. Therefore,
there is a need to have new technology which will be robust, efficient and stable for both crack
detection in railway track as well as object detection. This project discusses a Railway track crack
detection using sensors An Arduino Microcontroller is used to control and coordinate the activities
of this device
ARDUINO UNO
• Now, let me introduce another member of AVR microcontroller
family, the ATmega8. This member has many features similar
to that ofATmega328. But it has reduced number of features
and capabilities, yet it has enough features to work with. Now
let me tell you that if you want to gather knowledge and at the
same time want to do it in less cost than the budget
of ATmega382, you can think of making projects
with ATmega328. In that case, one feature you won’t be able
to realize is the JTAG interface. But rest of the features are
available in this IC. Let us see what one can get from ATmega8
POWER SUPPLY
• POWER SUPPLY:

• Power supply block consists of following units:

 Step down transformer.

 Bridge rectifier circuit.

 Input filter.

 Voltage regulators.

 Output filter.

 Indicator unit.
LCD DISPLAY
• LCD (Liquid Crystal Display) screen is an electronic display module and find a
wide range of applications. A 16x2 LCD display is very basic module and is very
commonly used in various devices and circuits.
• These modules are preferred over seven segments and other multi segment LEDs.
• The reasons being: LCDs are economical; easily programmable; have no
limitation of displaying special & even custom characters (unlike in seven
segments), animations and so on
BUZZER
• The piezo buzzer produces sound based on reverse of the piezoelectric
effect. The generation of pressure variation or strain by the application
of electric potential across a piezoelectric material is the underlying
principle. These buzzers can be used alert a user of an event
corresponding to a switching action, counter signal or sensor input.
They are also used in alarm circuits
Ultrasonic sensor
• Ultrasonic sensors (also known as transceivers when they both send
and receive) work on a principle similar to radar or sonar which
evaluate attributes of a target by interpreting the echoes from radio or
sound waves respectively. Ultrasonic sensors generate high frequency
sound waves and evaluate the echo which is received back by the
sensor. Sensors calculate the time interval between sending the signal
and receiving the echo to determine the distance to an object
DC MOTOR
• DC motors are configured in many types and sizes, including brush
less, servo, and gear motor types.
• A motor consists of a rotor and a permanent magnetic field stator. The
magnetic field is maintained using either permanent magnets or
electromagnetic windings.
• DC motors are most commonly used in variable speed and torque.
APPLICATIONS
• FOR RAILWAY SECTORS
• ROBOTIC SYSTEM
• INDUSTRIAL PURPOSE
ADVANATAGES
• HIGH ACCURATE SYSTEM
• SIGNAL QUALITY GOOD
• LOW POWER CONSUMPTION
