Any sensor requires calibration in order to be useful as a measuring device. Motor Engine (Spur Gear Mechanism) Railway Track Batteryġ2 IR SENSORS A sensor is a transducer used to make a measurement of a physical variable. IR Sensor FM transmitter and Receiver Unit D.C. The main components of the automatic railway track crack detecting vehicle are given bellow.
This signal turns the relay circuit ON which gives an alarm about the crack in the track.įM TRANSMITTER FREE RUNNING OSCILLATOR FM AMPLIFIER DRIVER TRANSMITTING ANTENNA FM RECEIVER The transmitted signal is received by the receiving aerial at the nearest railway station. FM TRANSMITTER FM Transmitter unit is used to activate the receiver unit when the signal is received from IR sensors. Once the crack is detected, the signal is sent to the FM transmitter unit. They use infrared light to sense the crack in the railway track automatically. SENSOR FM RECEIVER FM TRANSMITTERĨ SENSOR The sensor used in our project is IR sensor. Block diagram consist of following three parts. 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.Ĥ 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 trackĦ BLOCK DIAGRAM The block diagram of the Automatic railway track crack detecting vehicle is shown in fig. Safety measures employed now is not effective especially in the method of crack detection of rails. Presentation on theme: "S0LAR AUTOMATIC RAILWAY TRACK CRACK DETECTING VEHICLE"- Presentation transcript:Ģ S0LAR AUTOMATIC RAILWAY TRACK CRACK DETECTING VEHICLEģ 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.
