스마트폰과 블루투스 통신을 이용한 태양광 인버터 모니터링 시스템 구현
제현우,양오,Je, Hyun-Woo,Yang, Oh 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.10
The monitoring of the existing inverter is being implemented using a local computer of web monitoring, but in this paper, the remote monitoring system of the power condition system was implemented using a Bluetooth communication at a convenient position for the user that can be monitored without the computer. The proposed system was designed to be able to monitor the wanted information by using the protocol of inverter. Also when the power condition system has failed, the fault history and the generated time of inverter were stored in the Bluetooth device. Finally the performance of the proposed system was evaluated through experiments, it showed the good performance and the possibility of commercialization. 기존의 인버터에 대한 모니터링은 로컬컴퓨터나 웹 모니터링 등을 이용하여 모니터링을 하고 있다. 그러나 본 논문에서는 블루투스 통신을 이용하여 사용자가 편리한 위치에서 컴퓨터를 사용하지 않고도 태양광 인버터를 원격 모니터링 가능한 시스템을 구현하였다. 제안한 시스템은 인버터 프로토콜을 이용하여 인버터의 원하는 정보를 무선 통신으로 모니터링 할 수 있게 설계 하였다. 또한 태양광 인버터의 고장시 블루투스 고장이력과 시각을 기록할 수 있도록 하였다. 마지막으로 본 논문에서 제안한 시스템이 실험을 통해 좋은 성능을 보여주었고 또한 상용화의 가능성을 제시해 주었다.

스마트폰을 이용한 태양광 인버터의 원격 모니터링 시스템
제현우(Hyun-Woo Je),양오(Oh Yang) 한국정보기술학회 2012 한국정보기술학회논문지 Vol.10 No.1
Due to the development of diverse applications, smartphones are becoming more popular within the public. In this way, the smart-grid system is being implemented widely in order to optimize the energy efficiency. The existing Photovoltaic Inverter that was used exclusively until now could not identify what kind of problems there were in the grid information through the narrow LCD. In order to overcome these problems, Android designed the mobile Photovoltaic Inverter monitoring application, and through this the mobile information sharing system was designed and implemented in order to efficiently share the information of the inverter. By combining the smartphone with a high-speed internet network, real-time monitoring and operation statuses were able to be confirmed through the smartphone screen anytime and anywhere by connecting the Photovoltaic Inverter, which as a result, got rid of the inconvenience of the existing inverter. In this paper, the smart-grid system was built by using a smartphone to monitor the operation status of the grid-type Photovoltaic Inverter connected by the Wi-Fi module.

지그비 통신을 이용한 태양광 인버터의 원격 모니터링 시스템

The monitoring of the existing inverter is being implemented using a local computer or web monitoring, but in this paper, the remote monitoring system of the photovoltaic inverter was implemented using a Zigbee communication at a convenient position for the user that can be monitored without the computer. And the proposed system was designed to be able to monitor the wanted information of the photovoltaic inverter through the wireless communication by using the protocol inverter. This paper has extended from the existing 1:1 communication to 1:N communication with the protocol ID number and Zigbee module PAN(personal area network) ID in order that each communication has solved the problem of interference. Also when the photovoltaic inverter has failed, the fault history and the generated time of inverter were stored in the Zigbee device by inserting the RTC(real time clock). Finally the performance of the proposed system was evaluated through experiments, it showed the good performance and the possibility of commercialization.

양면 태양광모듈과 불활성기체 충진층을 적용한 수직 융합형 방음벽 개발에 관한 연구
정상훈(Jung, Sang-hoon),제현우(Je, Hyun-woo),노광민(Noh, Gwang-min),박원균(Park, Won-kyun),채종술(Chea, Jong-sool) 대한설비공학회 2017 대한설비공학회 학술발표대회논문집 Vol.2017 No.6
Applied technologies of solar energy, as an alternative energy source to the fossil fuel, became the main part in developing renewable energy resources. As sound-proof walls are commonly constructed around urban roads passing through the cities, it is required to develop the new technology to produce solar power using them with solar cells in the roads. While Japan and the United States have already built the convergence sound-proof wall with a photovoltaic system, Korea has not developed relevant technologies related to the sound-proof wall yet. In this study, as an alternative to the relevant technical improvement, we design the vertical convergence sound-proof wall and propose the applicable technology using bi-facial solar cells and inert gases.
