Abstract

Almost all existing inspection methods for catenary system have relied on dedicated track inspection cars. Two factors make it necessary to modify the conventional method: First, the climate has become increasingly similar to that of a subtropical area. In addition, high speed trains have been developed that can run as fast as 450Km/h. This paper presents a visual catenary inspection system structure that incorporates roadbed information for high-speed running environments. Conventional catenary inspection systems determined the degree of wearing only for the trolley wire. The facility inspection system presented in this paper on the other hand utilizes visual and sound data of inspection targets and adjusts inspection frequency and sensitivity depending on the geographic data.

지금까지의 전차선 검측 시스템은 검측차량을 이용하여 검사구간을 주행 한 후 결과를 산출하였다. 이것은 아열대기후로의 변화에 인한 자연 환경의 급변과 450Km/h급 고속철도 차량의 등장으로 변화가 요구된다. 이에 고속 주행환경과 노반정보를 반영하는 융합 가변형 전차선 검측시스템의 구조를 연구하였다. 기존의 시스템은 전차선에 한정하여 마모의 정도를 판단하였다. 이에 비해 본 논문에서는 검지를 위하여 참조하는 정보를 검측대상의 영상정보에 추가하여 음향정보를 융합하였고, 지형정보에 따라 검지빈도와 정밀도를 가변적으로 적용함으로써 시설물 검측에 대한 기본적인 모델을 제안하였다.
