Force Sensing Resistor(FSR)를 이용한 비침투식 배관 압력 모니터링 센서 연구

국문 초록 (Abstract)

산업화가 진행됨에 따라 상수도관 등 노후화된 배관이 증가하고 있다. 예기치 못한 파손에 따른 손실을 최소화하기 위해, 배관 누설을 실시간으로 감시·진단하여 사고대응 시간을 단축할 수 있는 기술에 대한 중요성이 증가하고 있다. 본 연구에서는 배관 외부에 설치하여 실시간 압력 측정이 가능한, 비침투식 배관 압력 모니터링 센서를 제안하고 연구를 수행하였다. 먼저, 배관 내 압력 변화와 FSR(force sensing resistor)에 작용하는 접촉하중 변화의 상관관계를 이용하는 비침투식 센서의 개념을 정의하고, 비침투식 센서의 성능 시험을 위해 6-inch 배관을 대상으로 센서의 형상 및 구동회로 설계를 위한 파라미터 연구를 수행하였다. 연구를 통해 도출한 설계안을 바탕으로 무선의 비침투식 배관 압력 모니터링센서를 제작, 테스트베드 배관에 설치하여 배관 내부 압력의 실시간 모니터링이 가능함을 검증하였다.

Various leakage detection techniques have been researched to prevent increased pipeline failures and corresponding human and economic losses. In this study, a non-intrusive pipeline pressure monitoring sensor that can be installed outside the pipe is proposed. First, we defined the concept and analytical model of the non-intrusive pipeline pressure monitoring sensor, which was based on the correlation between the contact force on a force sensing resistor (FSR) and the pressure in a pipe. Next, a parametric study was conducted using a 6-inch pipe to design the shape and operating circuit of the non-intrusive sensor. Based on the derived design parameters, a wireless non-intrusive pipeline pressure monitoring sensor was manufactured, and it’s performance on monitoring the internal pressure of the pipe was validated in the testbed.
