고속철도 신호 검측모듈 개발에 관한 연구

A maintenance for High speed railway facility has been developed from inspection by personnel to the automated way by the detection devices. In particular, the signalling equipment in order to increase the safety operation and efficiency of the trains is required to maintain normal operation by periodic maintenance. Because the return current gives the most important effects to the wayside equipment in the failures, a method is needed to measure the unbalanced rate of return current on the train driving at high speed. The HDB device has a function to recognize the abnormal axle by detecting the temperature that occurs in the axle. Therefore, it is required the device to validate the track sensor of HDB. In this paper, we propose the scheme for the requirements to develop the devices for the unbalanced return current and the validation of HBD track sensor, measuring resolution, estimation of measuring data and etc.
