EARLY WARNING SYSTEM FOR UNMANNED RAILWAY CROSSING USING VIBRATION SENSOR PLACED AT RAILWAY TRACK.

摘要

We have placed Vibration sensors at the Railway tracks of Railway network. Running of the Train on Railway tracks generate vibrations. These vibrations are transmitted ahead of train at a speed of sound. The propagation of the sound wave is positive and sure as the track forms a single entity due to the wielding joints through out the length of the track. The vibration thus generated by approaching train can be sensed, measured and used to issue a early warning by way of warning lights and sound siren at the unmanned Railway crossing
