As the internet communication is prevalent in recent years, it becomes quite possible to monitor and control some mechanical plants from the remote place through the TCP/IP communication. Such a concept is expected to be applied to many industrial systems for easy maintenance and trouble shooting as well as various kinds of expensive test equipments for sharing. In this research, remote data monitoring and speed control for a DC-motor is implemented and tested through TCP/IP communication with embedded micro-controllers. It showed the possibility of reliable remote control system design utilizing the internet communication.

The AC induced voltage on underground pipelines not only do harm to workers and instruments, but also cause big trouble in some case. This paper gives the mechanisms, examples, and countermeasure for the AC induced voltages which are caused by the resistive coupling between the grounding system of the 22.9kV distribution power system and the underground pipeline.

북제주 내연기관 발전기는 설비 노후로 인하여 경미한 고장이 점차 확대되고 기관 핵심 부품들의 손상이 증가하여 발전원가를 상승시키는 주요요인이 되고 있었다. 즉 정비 부품 교체 비용이 증가하고, 복구 시간이 장시간 소요되는 등 문제점을 안고 있었다. 이러한 문제점을 해결하기 위하여, 기관의 핵심요소인 실린더와 베어링의 상태를 연속 감시하고, 고장을 미리 발견 조치할 수 있는 컴퓨터시스템에 대하여 논하고자 한다.
