3 1. 서론 1.1 연구 / 개발목적 스마트홈이란인터넷기반의정보화가생활속에깊숙히자리잡은요즈음에이르러단순한가정내네트워크의연결이아닌주택 ( 건물 ) 내의정보기술요소를구현하는토탈홈정보제어시스템및서비스 / 솔루션을총칭하는개념이다. 스마트홈은물리적보안, 센서, 스토리지, HostPC, 음성인식, 텔레매틱스, DTV 등다양한산업분야를융합한복합산업이며, 산업간파급효과가큰가치사슬을통해지속적으로부가가치를창출할수있는신성장산업이다. 본연구에서는한백전자의 HBE-SMⅢ-SV210 키트를이용하여스마트홈의가장기본이라고할수있는원격제어 / 보안서비스를만들어본다. 1.2 요구사항 인터넷을통해집의가전제품 / 조명등을원격제어할수있다. PC뿐만아니라스마트폰 ( 안드로이드, 아이폰포함 ) 에서자유롭게사용가능해야한다. 호환되는가전제품에서만사용되는것이아니라범용적으로, 간단한장치의설치만으로도가정에서직접사용할수있어야한다. 기존의사용방법 ( 수동으로제어 ) 으로도가전제품을제어할수있고, 동시에인터넷으로도제어가능해야한다. 현재가전제품의상태를실시간으로원격에서알수있어야한다. 2. 구현방법 2.1 개념도 1사용자 UI 제공 JQuery와 JQTouch를이용해스마트폰의앱과비슷한 UI를가진웹어플리케이션을만들수있다. 2인터넷접속한백전자 SDK는베이스보드를통해이더넷인터페이스를제공하여인터넷에접속할수있다.

5UART통신한백전자 SDK는두개의 USART 단자를제공하며, 이를통해다른디바이스와 USART통신을할수있다. 2.

4 3실시간모니터링 AJAX 기술을통해비동기적으로디바이스의상태를받아갱신하여실시간으로사용자에게보여진다. 4웹서버리눅스기반의 GoAhead 웹서버를통해한백전자 SDK를이용웹서비스가가능하며, CGI를통해사용자가원하는서비스를제공한다. 5UART통신한백전자 SDK는두개의 USART 단자를제공하며, 이를통해다른디바이스와 USART통신을할수있다. 2.2 제품설계 본프로젝트에서는구현의편의상가전제품을 LED 로대체하여구현하였다. 2.3 웹설계 HTML 과 AJAX 를통해실시간성을띄며, JQuery 와 JQTouch 를통해깔끔한이미지를구현할 수있다. 메인화면 DashBoard 화면

5 Control Panel 화면 거실 Switch About 화면 2.4 SM3-SV210 프로그램설계 디바이스와통신하기위해리눅스의 UART디바이스드라이버 ttysac2를사용하였으며, 출력된값을 HEX형태로받아와비트단위로판별하여사용한다. 웹에서사용할수있도록 CGI의형태로사용되며, 디바이스와통신하며웹상에서서비스를제공하게된다. 이번에제작한서비스는각가전제품의상태를알려주고, 각가전제품의상태를제어 (On/Off) 하는기능을가진다.

6 2.5 디바이스설계 설계의방법은 ATMEGA128 을이용하여구현하였으며, 디바이스가 H/W 포트출력을지속적으 로읽어 USART 로출력하고, USART 로입력이들어온다면인터럽트루틴으로들어가장치를제 어한뒤복귀한다. 2.6 하드웨어설계 JK플립플롭을이용해현재의상태를기억하며, 스위치입력 ( 클럭펄스 ) 을이용해 J-K를묶은곳에넣어주면, 플립플롭의출력을반전시킬수있다. JK 플립플롭은 HD74LS76AP를사용하였고, HD74LS76AP에는두개의플립플롭이들어있으므로, 회로를두개씩묶어서제작하였다. C1015 트랜지스터는릴레이를구동시키기위한증폭용으로사용하였다.

7 3. 동작확인 완성된하드웨어 수동 Switch On / OFF

8 상태창확인 거실 Switch On

상태창바뀐화면 (LIVING ROOM OFF -> ON) 4. 결론 이번임베디드의프로젝트는기존과목들의프로젝트와는다르게리눅스환경에서의개발뿐아니라마이크로프로세서Ⅱ과목에서배웠던 ATMEGA128과이전에수업을통해배워보지못한 HTML을통한웹서버를구축함으로서, 다양한기술들을융합하고조합을시킨프로젝트이다.

9 상태창바뀐화면 (LIVING ROOM OFF -> ON) 4. 결론 이번임베디드의프로젝트는기존과목들의프로젝트와는다르게리눅스환경에서의개발뿐아니라마이크로프로세서Ⅱ과목에서배웠던 ATMEGA128과이전에수업을통해배워보지못한 HTML을통한웹서버를구축함으로서, 다양한기술들을융합하고조합을시킨프로젝트이다. 물론지금까지의프로젝트와는새로운방법을사용하였기때문에많은수많은시행착오를하였다. 서로규격이다른통신을하기위한프로토콜구축과이전에해보지못하였던 JQuery 와 JQTouch 그리고현상태를실시간으로확인하기위한 AJAX등의기술들을사용하면서어려움도많았지만그만큼많은것들을배울수있던좋은기회였다. 다만아쉬운적이있다면, 통신의방식에너무많은신경을썼기때문에동작여부를확인할수있는방법을단순하게 LED를사용하였던것이매우아쉽긴하지만, 많은기술들을직접구현하여사용해보았다는것에큰의미가있는것같다. 또한앞으로취업을준비함에있어서앞으로발전할기술인스마트홈을직접만들어보고제어해본경험은학창시절에서잊지못할경험중하나로남을것이라고생각이되며, 이번프로젝트를통해서나만의커리어를만들수있게된것같다. 앞으로기술이더욱발전을하여실생활에서더욱발전된모습의스마트홈에서생활을할수있었으면좋겠다.
