Abstract

This study was aimed at investigating the applicability of energy harvesting technologies, which are regarded as new and renewable energy sources for real-time/wireless monitoring of intelligent railroad vehicles. The surrounding energy generated in a normal operating environment was monitored using a high-speed railroad vehicle in operation. This monitoring was performed in an attempt to evaluate the effectives of energy harvesting and the applicability of energy-harvesting-monitoring technologies under the conditions in which thermal energy and vibration energy are generated.

본 연구에서는 실시간 무선 철도시스템 모니터링을 위하여 열차 주행에 따라 발생하는 열 및 진동 에너지를 전기자원화 하는 신재생 에너지 개념의 전력원인 자가발전 구동 기술에 대한 철도시스템 적용 가능성을 확인하였다. 이를 위해 실제 주행 중인 고속열차를 이용하여 철도차량의 운행환경 하에서 발생하는 열에너지와 진동에너지를 실측하여, 주행 중 이들 에너지 발생량 및 변화를 분석하고 이를 통해 진동 및 열 에너지를 이용하는 자가발전 모듈의 예측 전력량을 계산하고, 이 전력량에 대한 이 모니터링 시스템 적용 가능성에 대한 연구를 수행하였다.
