Structural Health Monitoring of Railway Tracks Using WSN

Wireless sensor networks have emerged as a promising technology in last few years, that encouraging a deep innovation in the field of structural monitoring. The main benefits of wireless sensor networks are little interference, self-organization and fast deployment. Structural Health Monitoring (SHM) implements a detection of damages and characterization strategy for engineering structures. For railway track main concern regarding SHM are alignment of tracks, formation of crack, corrosion of tracks material, deformation of tracks and missing tracks. In current scenario Structural health monitoring of railway track is done using various methods like oral communication through telephone, wired sensor network deployed over railway tracks, through GPS communication technology but response time of these methods is high. This proposed method aims to implement Wireless Sensor Network (WSN) for Structural Health Monitoring (SHM) of railway tracks. This prototype will enhance the response time over existing system and also reduce cost from existing system.
