IoT(사물인터넷) 시대에 하드웨어 장치의 수와 종류는 지속적으로 증가하고 있습니다. 인프라 장비에는 여러 IoT 장치가 활용됩니다. 이러한 IoT 장치를 어떻게 유지 관리할 것인가는 심각한 문제입니다. 커패시턴스 측정 하드웨어 장치 구조의 비정상적인 상태를 감지하는 강력한 방법 중 하나입니다. 특히, 하드웨어 장치가 실행되는 동안 정전 용량을 측정하는 것은 주요 과제이지만 현재까지 제안된 연구는 없습니다. 본 논문에서는 동작 중 소자의 정전용량을 측정하는 정전용량 측정장치를 제안한다. 먼저 AC(교류) 전압 신호와 DC(직류) 공급 전압 신호를 결합하여 변동하는 신호. DC 공급 전압을 공급하는 대신 변동하는 신호를 대상 장치에 공급합니다. 대상 장치에서 관찰된 전류를 효과적으로 필터링함으로써 필터링된 전류는 커패시턴스 값에 비례할 수 있으므로 대상 장치의 커패시턴스를 실행 중에도 측정할 수 있습니다. 제안된 정전용량 측정 장치를 95mm × 70mm 크기의 인쇄회로기판에 구현하고 소비전력과 정전용량 측정의 정확도를 평가하였다. 실험 결과는 제안된 정전용량 측정 장치의 전력 소모가 측정 모드 대비 저전력 모드에서 65% 감소함을 보여주며, 제안 장치는 0.002μF 분해능에서 정전용량 측정에 성공하였다.

Abstract: In IoT (Internet-of-Things) era, the number and variety of hardware devices becomes continuously increasing. Several IoT devices are utilized at infrastructure equipments. How to maintain such IoT devices is a serious concern. Capacitance measurement is one of the powerful ways to detect anomalous states in the structure of the hardware devices. Particularly, measuring capacitance while the hardware device is running is a major challenge but no such researches proposed so far. This paper proposes a capacitance measuring device which measures device capacitance in operation. We firstly combine the AC (alternating current) voltage signal with the DC (direct current) supply voltage signal and generates the fluctuating signal. We supply the fluctuating signal to the target device instead of supplying the DC supply voltage. By effectively filtering the observed current in the target device, the filtered current can be proportional to the capacitance value and thus we can measure the target device capacitance even when it is running. We have implemented the proposed capacitance measuring device on the printed wiring board with the size of 95mm × 70mm and evaluated power consumption and accuracy of the capacitance measurement. The experimental results demonstrate that power consumption of the proposed capacitance measuring device is reduced by 65% in low-power mode from measuring mode and proposed device successfully measured capacitance in 0.002μF resolution.
