Smart energy harvesting for intelligent railway condition monitoring system [articol]

Abstract

Remote sensor systems are utilized for observing the railway structures like spans, rail tracks, track beds and track hardware. The requirement for railway monitoring system is vital. This paper describes about cyber physical system which is controlled by the computer based algorithms for remote transmission of information. The arrangements of remote sensor modules like accelerometer, temperature sensor, humidity sensor and IR detector for monitoring the distinctive specifications of railways are also explained. The vibration from the rail track produces energy to power up the remote sensor modules. The end device is controlled by a magnetic levitation energy harvester. The energy harvester is chosen because of its wide band reaction qualities. The transmission of data is done wirelessly by wireless RF device. The rail tracks are monitored by the railway system and the monitored information are stored in the work stations hard drive and the movement of train is controlled by the provided information.
