Fuzzy logic based railway track condition monitoring system

Abstract

In recent years, the need to improve the quality and comfort of railway passengers, there has been increased demands to reduce the level of noise and vibration, experienced during travel. Different researches have focused on reducing the level of vibration. Track irregularities are the main causes of vibration and thus carefully monitor the parameter to improve the ride quality. Vibration may arise vertically and laterally, in this vertical vibration is higher. In this paper, we proposed a new method called Fuzzy Track Monitoring System (FTMS) for estimating the irregularities present in the railway track at running time. The vibration sensor is mounted on the axel box and the bogie of the train for measuring the acceleration in the lateral and vertical directions. The system automatically tracks the location of vibration and sends it to the central office. The performance of proposed approach was studied and it proves that the proposed approach is capable for real time measurements.
