However, LED-LDR cannot check for surface and near-surfacecracking where many of the faults are located.

Railway Track Detection System Project Ppt Serial Input Port Port 0 Port pin Functionsp0.0 p0.8 TXD( UART)p0.1 p0.9 RXR (UART) Low power consumption. Transmit the signal to the gate level section and to controlthe level crossings by DC motor interface with c. LCD is used to display the which damage status occur onthe track. RF Module used to transmit and receivesignals from one section to another. If any obstacles, crack on the trackdetected by ultrasonic sensor. In track, any shaketilt in parallel bridgeposition sensed by MEMS.

Transmitting the information to the current train which comes on thetrack.Advantages: Very accurate detection. MEMS sensor is used for detect the cracks and breakage of tracks. Ultrasonic sensors are used for monitoring the obstacles in tracks. The system can be operated at tunnels also, without interrupts. It can be operated in tunnels with interruption.Disadvantages: Delay in transmitting the information.
