摘要

发现并设计了用于振动能量收集的Galfenol磁伸缩装置。基于应力变化对Galfenol中高磁通波动的影响，可以在Galfenol周围缠绕感测线圈产生电压。本文提出了一种基于Galfenol振动磁致伸缩传感器的铁路监测方法。Galfenol磁致伸缩传感器产生的能量可以提供给无线模块，将占用的轨道信息和列车位置传输到铁路运行控制中心。在实验中，介绍了传感器的特性和铁路检测实验。

Energy free railway monitoring with vibrating magnetostrictive sensor for wireless network sensor

Galfenol magnetostictive device was discovered and designed to used as energy harvesting from vibration. Based on stress variation effects to high magnetic flux fluctuation in the Galfenol, voltage can be generated with sense coil wound around the Galfenol. This paper presents railway monitoring based on Galfenol based vibrating magnetostrictive sensor. Energy generated from Galfenol magnetostrictive sensor can be supplied to the wireless module in order to transmit occupied track information and train location to railway operation control center. In experiment, sensor characteristics and railway detection experiment is presented.
