TRAIN COLLISION AVOIDANCE

Train collision Avoidance – Embedded Logic

TRAIN COLLISION AVOIDANCE

•Train derailment in curves and bends •Running Train collisions with the standing Train•Train Accidents in slopes•Mis-signaling due to fog or mist

TRAIN COLLISION AVOIDANCE

The different blocks used to avoid the Collisions:1.Gap Detector2.Vibration Sensor3.Proximity LASER Detector4.LED lighting or Fog penetrating Lights5.FSK Modulator and FSK Demodulator ( Power Line Communication) .A Microcontroller for entireControl. The Microcontroller is interfaced with the input sensing devices such as vibration sensor, Gap Detector andproximity LASER Detector.

Result and Discussion

The sensors sense the input and sends to the microcontroller, where it responds and givescommand to the particular component with predefined algorithm. The time parameters are crucialwhich can be easily changed and modified using Micro-controllers. Thus, this device would work incoherence would help to reduce the train collisions.
