Intelligent distribution automation system have total monitoring and control capability. The system covers substation, distribution network, distributed generations and customers at HV system. Various intelligent distribution facilities installed at distribution systems have voltage sensor, current sensor, aging monitoring sensor. Intelligent Feeder Remote Terminal Unit (IFRTU) tied to intelligent distribution facilities process information from facilities and it checks information of fault, power quality and aging of distribution facilities. The information is transmitted to master station through communication line. The master station have remote monitoring system covers substation, distribution network, distributed generations and customers. It also have various application programs that maintain optimal network operation by using information from on-site devices.

In this paper, we described the integrated monitoring system for low-voltage panel boards. This system consists of three parts, a panel board controller, an integrated monitoring unit and a remote PC. The panel board controller which was made of CT/PT unit, control unit and power supply is able to transmit variable parameter for monitoring and diagnosis of low voltage branch circuits. Also, the integrated monitoring unit was collected monitoring data from panel boards and displayed on the touch panel.

In this paper design and implementation of ship's distributed remote control system using dual-microprocessor is presented for real time process. The proposed system is implemented with the single chip microprocessors in tightly coupled mode and results in speed up of $s_p$=1.74. Under the assumption that the nodes are interconnected in multidrop, the overall system performance such as average throughout-delay characteristics and effective throughput are analyzed using M/G/1 queneing model, and results show that the proposed node can be used in medium sized distributed monitoring and control system.

Most measuring devices are equipped with RS-232 or GPIB interface for communicating data with computers. If the measuring devices can be accessed by a server computer, the valuable information from the devices can be effectively shared with other computers via internet. But, if the measuring devices and the server computer are too far away, it is difficulty to directly connect them by RS232 interface. PSTN(Public Switched Telephone Network) refers to the world's collection of interconnected voice-oriented public telephone networks. Measuring computer system which is equipped with RS232 interface and modem for PSTN can be introduced to overcome the aforementioned distance problem, In this work, an internet based remote monitoring system which utilizes PSTN and VRML for 3-dimensional GUI is proposed.

In this paper, a new remote terminal unit(hereafter RTU) is proposed to manage a wide range of applications and a variety of sensors (eg, pressure, water quality, temperature and humidity sensors, the amount of pollutants, $CO_2$, etc.) to monitor and control the facility such as water treatment plant, intake and effluent pumping station, water tank and distribution network. Fault status of local sensor devices and network are alerted by using the embedded fault handling capabilities of the RTU in the system and also sent to the fault handling server, by which fault can be easily monitored to users. The developed system was applied to one of K-water branch offices in Geoje city and improved its reliability and stability for controlling and monitoring water facility.

일체형 등명기는 운항 중인 선박의 항로 선위를 결정하기 위한 등화장치이다. 현재 태양광을 기반으로 하는 일체형 등명기는 태양광의 일조시간에 따른 제약에 따라 전력 공급의 부족으로 항로 표시 가능한 능력이 제한적이다. 본 논문에서는 해상의 풍부한 전력원인 태양광과 풍력을 동시에 사용하는 신재생에너지 일체형 9해리 LED 등명기를 구축하고 원격 스마트 모니터링 시스템을 구현하였다. 또한 LED 등명기 장치와 모니터링 시스템을 IoT화 함으로서 등명기의 원격제어 가능한 스마트 제어시스템을 마련하였다. 본 원격 스마트 모니터링 시스템을 적용하여 실시간 상태 모니터링 및 원격제어가 가능하게 하여 선박이 안전한 항해를 할 수 있고 등명기 기능의 정확성 및 영속성을 유지하여 해양사고 예방과 사회적 비용을 절감할 수 있다.
