Abstract

Recently, interests for maintenance of transmission tower are increasing to extend life of structures and reduce maintenance cost. However, existing classical diagnosis method of corrosion deteriorated degree on the transmission tower steel members, visual inspection, has a problem that error often due to difference of inspector's individual knowledge and experience. In order to solve the problem, this study carried out to develop the corrosion deterioration inspection tool for transmission tower steel members. This tool is composed of camera equipment and computer-aided diagnosis system. We standardized the photographing method by camera equipment to obtain suitable pictures for image processing. Diagnosis system was designed to evaluate automatically degree of corrosion deterioration for member of transmission tower on the basis of the RGB color image processing techniques. It is anticipated that developed the corrosion deterioration inspection tool will be very helpful in decision of optimal maintenance time for transmission tower corrosion.

근래에 송전철탑의 수명연장과 유지관리 비용 절감을 위한 관심이 증가하고 있다. 그러나 송전철탑 부재의 부식 열화도를 진단하는 재래적인 방법으로서 육안점검은 점검자 개인의 지식과 경험의 차이에 따라 오류를 야기하는 문제점을 내포하고 있다. 이러한 문제를 해결하기 위하여, 본 연구에서는 송전철탑 강 부재에 대한 부식열화 검사장비를 개발하였다. 개발된 검사장비는 부식열화 영상 촬영장치 및 컴퓨터 기반 진단 시스템으로 구성된다. 영상처리에 적합한 열화영상을 확보하기 위하여 촬영장치를 개발하여 촬영방법을 표준화하였으며, 진단 시스템은 RGB 컬러영상처리 기법에 기초하여 송전철탑 부재의 부식 열화도를 자동적으로 평가하도록 설계하였다. 개발된 부식열화 검사장비는 송전철탑 부식에 대한 최적 유지보수 시기를 결정하는 것에 도움이 될 것으로 기대된다.
