Abstract

Typically electronic resistance type sensors have been used for measurement system of high-speed trains. But due to a large number of measurement quantities, we had difficulties in installing and maintaining the cables that connect sensors and measuring devices. Furthermore, signals obtained from the electronic resistance type sensors are often distorted because the sensors and cables are vulnerable to electro-magnetic interference (EMI). In this paper the characteristic of FBG sensors are compared with those of electronic resistance type sensors in application for the measurement system of high-speed trains. FBG sensors have advantages because of their multiplexing characteristic and robustness to EMI environment.
