Abstract

In this paper, we designed a low cost data logger system using single chip microcontroller. It detects the normal and abnormal current in distribution system. A sampled analog signals are stored on RAM card(4Mbit) after digitalized by internal A/D converter. Stored data can be transmitted to the personal computer either by internal serial communication port or by external parallel communication port. The transmitted data are analyzed and displayed on personal computer.

본 논문은 배전선로의 정상 및 비 정상상태의 전류를 감시하기 위해 싱글 칩 마이크로세서를 이용하여 저가격의 Data Logger를 구현하였다. 수집된 데이터는 내장된 A/D변환기에 의해 디지털화된 후 RAM Card에 저장된다. 저장된 데이터는 직렬 통신 및 별동의 RAM Card Driver를 통해 병렬로 퍼스널 컴퓨터로 전송할 수 있도록 하였다. 수집된 데이터는 퍼스널 컴퓨터상에 디스플레이가 되도록 하였으며 분석할 수 있도록 하였다.
