BACnet(Building Automation and Control Networks) is a standard data communication protocol specifically designed for building automation and control systems, BACnet provides six options for data link layer protocols and these six data link layer options can be applied with various wired transmission media. Recently wireless technology prevails in automation area. ZigBee is an IEEE 802.15.4 based standard communication protocol for low-rate wireless personal area networks. In this study, we propose a BACnet over ZigBee model that adopts ZigBee communication channel as a wireless data link layer protocol in a BACnet-based communication network system. The technology proposed in this paper can expand the BACnet application using the advantages of wired and wireless integrated network solution.

Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.

건축공사에서 먹매김 공정은 건물의 구성요소를 계획된 위치에 정확히 형성하기 위한 기준이 되므로 높은 정밀도가 요구된다. 최근의 건축물 규모 증가 및 숙련공 부족 추세에서 먹매김 공사는 로봇 기반의 자동화 기술 도입을 통한 생산성 및 품질 향상 요구가 크게 나타나고 있으며, 특히 가장 선행되는 골조공사 먹매김 작업의 중요도 및 자동화 필요성은 더욱 크다고 할 수 있다. 이러한 배경에서 본 연구는 건축물 골조공사용 먹매김에 적합한 시공 자동화 시스템 개발 방향을 제시하고자 한다. 기존 유사 기술 고찰을 토대로 하여 5가지 구성기술과 17개의 세부 기술요소를 도출하였으며, 전문가 설문을 통한 중요도 평가를 수행하였다. 설문 결과, 열악한 주행 및 작업 환경에 대응하기 위한 주행부 및 마킹부 기술이 가장 중요한 구성기술로 파악되었으며, 이러한 환경에서 정밀도를 확보하기 위한 제어기술과 전반적인 프로세스의 자동화기술의 중요성이 높게 나타났다. 본 연구 결과는 향후 보다 실용적이고 효율적인 자동화 시스템 개발에 기여할 것이다.

빌딩자동제어시스템은 여러 서브시스템의 통합을 통한 고도의 서비스 제공, 관리비의 절감 등을 효과적으로 실현할 수 있다. 통합운전의 전제조건은 표준 프로토콜을 가진 개방형 네트워크를 이용하여 합리적인 네트워크 설계에 있다. 따라서 본 논문에서는 BAS에 가장 걸림돌이 되었던 화재경보시스템(소방법 명칭)을 ANSI/FIA 709.1인 LonTalk 프로토콜을 이용하여 BAS에서의 통합을 위한 개념적인 새로운 설계방안을 제시하였다. 기존 시스템에서 사용되는 중계기를 대체하는 지능형제어모듈을 개발하고 이를 이용하여 개방된 지능형 화재경보시스템의 설계방안을 제안한 것이다. 이는 오보률의 저감 실현은 물론 빌딩의 통합운전에도 크게 기여할 것으로 판단된다.

Nowadays, social environment is rapidly changed toward globalization and information age, and which demands the new paradigm for active utilization of information system in the field of education and many others. The effort to adapt tele-communication technique to educational facilities and the planning to make virtual university come true are needed immediately. Intelligent Building system should be applied to educational facilities to cope with the changing and progressing building system. As a result of the surveying eleven domestic universities, it was found that library management system, administration automation system and office automation system were already introduced, but campus infrastructure such as network system and tele-communication system between buildings in campus have been constructed now. As the conclusion of this study, impeding factors and improvement direction for active utilization of intelligent building systems in university facilities were presented.

According to the realization of highly information dependent society, the recent building system is developed into the concept of suitable for management of intellegent work, which is demanded to unify of IBS(Intelligent Building System), IC(information communication), OA(office automation), BA(building automation) system and computer technology. However inspite of the presence arrester, cable shielding, insulated TR, filter, earth etc., in the IBS building for the cope with several surge and noise has several problems from the wrong operation of the equipment which caused from several surge, damage of equipment, and noise etc. And the miss operation caused by wrong earth works, which must be considered at first during the building construction. In order to minimize these problems, it's necessary that various earth project are performed effectively, and bonding methods between the mutual wiring of earth system and the equipments in the building should be improved sucessively. So in this paper, we analyze present domestic conditions of the earth technology in IBS building, and propose minimization method for the various surge and noise problem, and examine and analyze through the applied works.

Recently, higher and bigger building is trend of the construction. Accordingly the building material is getting bigger and construction equipments are developed. But operation is still depends on human resource. Therefore there have several problems that are safety, laborious operation, and shortage of worker. In the various construction sites, the automation in construction is introduced to solve these problems. This paper proposed the automation system in construction that installs curtain wall in a high building. The system is expected effects that are reduction of a construction period, retrenchment of the cost and assurance of safety.

Recently, the trend in architectural forms has been toward taller and larger building. The building materials, therefore, are getting larger and heavier as wall. Most of the construction projects are, however, dependent on outdated equipment and human resources. Construction processes up to now face a number of problems, including dangerous work, high construction cost and heterogeneous construction quality. In various construction sites, automation in construction has been introduced to address these problems. This paper proposes a human-machine cooperative system in the construction site; the system utilizes construction of a curtain wall in tall buildings. The use of automation system at construction sites can reduce the need of human involvement. Construction time and cost can be reduced as well. The most important aspect of the use of automation system at construction sites is prevention of accidents.
