전력선 가입자망은 그 잠재적인 활용도가 매우 높아 국내외 전력 회사들의 관심도가 매우 높아지고 있다. 기존의 단순한 전력 공급만을 목적으로 하던 수용가의 전력선을 통신망으로 이용하면 전기 이용은 물론 정보가전기기, 컴퓨터 기기 등의 홈 네트워킹, 홈 오토메이션 및 인터넷 통신이 가능하게 됨으로써 관련 업종의 경쟁력 제고와 전력 사용기기를 최적 제어함으로써 가정의 편리성과 에너지 효율을 극대화 할 수 있다. 또한 전력선망을 보유한 전력회사에서는 원격 수요관리, 검침 및 자동화 기술을 통하여 보다 효율적인 전력 운영과 수용가 이익을 증대화 시킬 수 있다. 본 논문에서는 전력선 통신을 이용하여 원격검침, 수요관리, 고객 관리 및 전력 정보 제공, 심야전력 관리 및 감시 등의 다양한 서비스를 경제적으로 제공하기 위하여 우리나라 실정에 맞는 전력부가 서비스 시스템의 주요 기기들을 설계하고 개발한다.

In this paper, we designed and implemented home gateway system for remote control of home appliances and devices using cellular phone. The system communicate home devices through Zigbee protocol and home server based on Linux operating system communicate cellular phone through external networks. We expect that the system apply various fields as home automations, home network, smart offices, and ubiquious environments.

As collaborative design and configuration design are of increasing importance in product development, it becomes essential to exchange the feature and parametric CAD models among participants. A history-based parametric method has been proposed and implemented. But each translator which exchanges the feature and parametric information tends to be heavy because to implement duplicated functions such as the identification of the selected geometries, mapping between features which have different attributes. Furthermore. because the history-based parametric translator uses the procedural model as the neutral format, which is the XML macro file, the history-based parametric translators need a geometric modeling kernel to generate an internal explicit geometric model. To ease the problem, we implemented a shared integration platform, the TransCAD. The TransCAD separates translators from the XML macro files. The translators for various CAD systems need to communicate with only the TransCAD. To support the communication with the TransCAD, we exposed the functions of the TransCAD by using the Automation APIs, which is developed by Microsoft. The Automation APIs of the TransCAD consist of the part modeling functions, the data extraction functions, and the utility functions. Each translator uses these functions to translate a parametric CAD model from the sending CAD system into the XML format, or from the in format into the model of the receiving CAD system This paper introduces what the TransCAD is and how it works for the exchange of the feature and parametric models.

The necessity of the home network have been enlarged gradually according to the distribution of ultra-high speed internet, the expansion of a digital information equipment and the change of a life pattern. In this paper, we proposed the embedded ethernet module that could be operate on eight bit system, but it could control home appliance with full ethernet speed. The embedded ethernet module consists of 8051 MCU and Hardware TCP/IP. In this module, we construct simple web server and port remote control program for I/O device control. We verified through internet that the developed embedded ethernet module could control and check home appliances anywhere and anytime. We expect the developed ethernet module can build up niche market at home network. And it will be helpful to activate home network market.

This study aimed to analyze residential demands on intelligent systems for apartments and suggest space design directions of intelligent apartment complexes. Data collection was done through mail-in surveys by five respondent groups. Outcomes of this study would provide basic data for developing intelligent apartment housing corresponding to the residential characteristics and demands of the five respondent groups. The sample size for the questionnaire survey was 592. The types of the target residents in this study were classified into five categories; nuclear families, dual income families, single households and the handicapped needing special environmental supports, and workers at home who need the new home design with a home office. The primary findings of this study were as follows. 1) For the controllers of intelligent system, nuclear families preferred TV, single households prefer home-pad which is movable and provides access to the internet. Dual income families, the handicapped and workers at home preferred remote control panels. 2) For the desirable space for computer equipment, regardless of the types of target residents, bedroom and living room were preferred. 3) For the desirable space for a home theater system, most of respondent groups preferred living rooms, but many rather wanted to have media rooms only for this system.

최근 IT분야에서 주목받고 있는 부분은 정보가전분야이다. 특히, 홈오토메이션(HA Home Automation)에서 중심이 되는 시스템은 홈서버라 할 수 있다. 즉, 가정내에 홈서버가 설치되어 이를 중심으로 내부적으로는 정보가전기기들이 네트워킹되어 있고, 밖으로는 인터넷을 기본 통신 환경으로 구성되는 것이 현실이다. 이러한 환경에서 홈시큐리티 방면의 영상감시기능은 핵심분야 중 하나이다. 영상감시기능을 수행하고자 가정의 홈서버상에 영상감시 모듈이 탑재되어진다. 이때, 홈서버는 임베디드 시스템으로 Qplus라고 하는 임베디드 리눅스 계열의 운영체제를 기본으로 하며, 영상감시 모듈은 SIP(Session Initiation Protocol)기반으로 수행된다. SIP은 VoIP(Voice over IP) 분야의 핵심기술로 최근 많이 부각되어 널리 활용되고 있는 응용 계층의 시그널링 프로토콜이다. 한편, 영상코덱은 ITU-T의 H.261표준을 따르고 있으며, 이러한 영상감시기능은 홈서버 뿐만 아니라, PDA와 같은 핸드헬드 장치를 통해서도 제공된다. 본 논문에서는 임베디드 영상가미 시스템의 설계 및 구현에 대해 기술하고 있다.

This paper proposes two systems. One is a Home Gateway(HG) which efficiently connects and controls digital appliances in the home network environments. The other is a Management Server(MS) that overcomes the physical limitation of the HG. The HG supports networking modules(TCP/IP for Ethernet, ADSL), home networking functions(HomePNA, IEEE1394 PLC) and telecommunication system(PSTN/SLT, VoIP, Video Communication). The HG is expected to be a core device for the integrated digital home environments. The MS is a dedicated server which manages and controls individual HG, home appliances and HA devices implemented at an area.
