S0LAR AUTOMATIC RAILWAY TRACK CRACK DETECTING VEHICLE PRESENTED BY 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 BLOCK DIAGRAM The block diagram of the Automatic railway track crack detecting vehicle is shown in fig. Block diagram consist of following three parts. Automated Visual Inspection/Detection of. Visual Inspection/Detection of Railroad Track. And photographs of the rail‐gage measurement system.

SENSOR FM RECEIVER FM TRANSMITTER 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. FREE RUNNING OSCILLATOR FM TRANSMITTER FREE RUNNING OSCILLATOR FM AMPLIFIER DRIVER TRANSMITTING ANTENNA FM RECIEVER COMPONENTS AND DESCRIPTION The main components of the automatic railway track crack detecting vehicle are given bellow. IR Sensor FM transmitter and Receiver Unit D.C. Motor Engine (Spur Gear Mechanism) Railway Track Battery IR SENSORS A sensor is a transducer used to make a measurement of a physical variable. Any sensor requires calibration in order to be useful as a measuring device. Calibration is the procedure by which the relationship between the measured variable and the converted output signal is established IR TRANSMITTER: The IR transmitting circuit is used in many projects. The IR transmitter sends 40 kHz (frequency can be adjusted) carrier under micro control (can turn the IR transmission on and off). IR carriers at around 40 kHz carrier frequencies are widely used in TV remote controlling and ICs for receiving these signals are quite easily available. IR RECEIVER: In our project IR transmitter and receiver circuits are used to detect the cracks in the track. IR receiver gives the control signals to the control unit. In our project IR transmitter and receiver circuit is used to senses railway track cracks. There are two pairs of sensor are used. Sensor 1: One side of the train track Sensor: Another side of train track Sensor 1 and Sensor 2 are used to senses the moving train engine and giving control signal to the FM transmitter unit. More details about the Sensors are already discussed in the above chapter. FM TRANSMITTER UNIT:- F.M transmitter unit is used to activate the receiver unit when the signal received from the IR sensors. 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.
