Abstract

Railway turnout systems play a key role in railway systems that change train directions. The turnout systems are one of the weakest systems in railway systems, and consecutive maintenance is required. A turnout diagnostic system can automatically measure the turnout status and its deterioration. To diagnose the turnout systems, we follow conventional maintenance procedures and need to identify their physical characteristics to coincide the procedures and the characteristics. According to the physical characteristics, we should choose and install adequate sensors on the turnout systems to measure their physical characteristics. We studied the phenomenon of the turnout system responses for point moving and train running on the turnout systems. We installed sensors on the turnout system in a revenue line to measure the identified physical quantities and to reveal the robustness of the sensors under the turnout system environment.

철도의 분기기 시스템은 철도에서 가장 중요한 시스템 중 하나로서, 차량의 진로를 설정한다. 분기기 시스템은 철도에서 가장 취약한 시스템 중 하나이며, 건전성을 유지하기 위해서 지속적인 관리가 필요하다. 분기기 진단 시스템은 분기기의 열화 상태를 자동적으로 측정할 수 있다. 분기기 시스템을 진단하기 위해서, 기존의 분기기 점검절차와 분기기에서 나타나는 물리적 특성을 규명하였다. 도출된 측정항목을 이용하여, 적절한 센서들을 선정하고, 영업노선에 설치하여, 데이터를 수집하였다. 본 논문에서는 분기기와 같이 열악한 환경에서 센서의 강건성과 데이터 획득에 대한 잡음 간섭 여부를 판단하였다.
