  • Buildings are becoming more and more high-rise and large-scale in recent years, so in the event of a disaster such as a fire, enormous human and economic damage is expected. Therefore, management, security, and fire control are essential for large buildings in the city. Because these large buildings are very complex outside and inside, they need a three-dimensional control based on 3D modeling rather than a simple flat-oriented control. To do this, this paper designed and implemented a building control system based on 3D modeling. Specifically, we designed a 3D building / facility editing module for 3D modeling of buildings, a 3D based control module for building control, and a linkage module that connects information such as firefighting equipment, electrical equipment and IoT equipment. Based on this design, a building control system based on 3D modeling was implemented.

  • In a recent years, there has been little change in basic mechanical and electrical design of material handling equipment. Reliability, safety. strength and controls have been improved. The most important change is sophisticated control and operation brough about by the tremendous improvement in computer capabilities. Even though the material handling equipment has been improved, material handling equipment must be selected properly. In this paper, the paper selection of material handling equipment using expert system will be presented.

  • 최근 국내 아파트의 외벽 거푸집공사의 경우 대부분 갱폼 시스템을 통해 철근콘크리트 구조체를 시공하고 있다. 이러한 갱폼 거푸집을 사용한 콘크리트의 경우는 거푸집 탈형 후 외부환경에 노출되고 특히, 건조한 봄, 가을과 일사량이 높은 서중시기의 벽량이 많은 아파트 측벽에 다량의 균열이 발생되어지고 있다. 이에, 본 연구에서는 신축 아파트 건설현장 중심으로 균열량이 많은 아파트 측벽부분의 갱폼시스템에 습윤양생 자동설비장치를 적용하여 초기 콘크리트 양생에 필요한 수분을 공급함으로써 콘크리트의 품질확보와 다량의 측벽균열 저감을 통한 습윤양생 자동장치의 효율성 및 활용성을 검토하고자 하였는데, 그 결과, 양생 효과 및 낙수량 고려 시 습윤양생 자동장치에 0.3mm 사이즈의 노즐을 사용하여 살수양생을 실시할 경우, 자원낭비 없이 콘크리트의 품질향상 및 균열저감에 효과적인 것으로 판단되었다.

  • Electric Vehicle Supply Equipment(EVSE) is a system or an equipment to supply electric power for charging the traction batteries on the electric vehicle. Control Pilot is an electric signal generated by EVSE and is transmitted to the electric vehicle by a vehicle coupler and a contact. The duty cycle of control pilot determines the maximum current to be drawn by electric vehicle. When the duty cycle is 5%, it is indicated that digital communication is needed. This paper deals with the data format and definition about communication scheduling through the inband signal on the control pilot of EVSE.
