Collision Avoidance and Crack Detection on Rail Track

Wireless Sensor Networks (WSN) have been employed in a wide range of applications due to the low-cost and ease of installation features. Few of its important applications are in road safety, highways field, Rail track maintenance field etc. The instant detection of collisions with the guardrails will allow to minimize the consequences of an accident or disaster. In a collision detection, all the intervention mechanisms in emergency aid and support to victims can be triggered, allowing a fast response by the emergency and rescue teams. At the same time, the security procedures are activated in order to inform in real time prior to arrive. In this context, wireless sensors have been employed in order to monitor and report the conditions of the rail tracks. Global System for Mobile Communication (GSM) is implemented for conveying the message regarding the rail tracks to the concerned person with Global Positioning System (GPS) used for tracking the location where the problem arises along with an Automatic Speed Control Mechanism of adjusting the speed using motor controlled by relay.
