Abstract

가정자동화 시스템에 있어서 주제어장치와 다수의 단말장치 사이에 효율적으로 회선을 연결 및 관리하고 원할한 메세지 통신이 가능하도록 하는 회로 및 방법에 관한 것이다.The present invention relates to a circuit and a method for efficiently connecting and managing a line between a main control device and a plurality of terminal devices and enabling smooth message communication in a home automation system.

주제어장치와 여러 단말장치를 하나의 회선에 멀티포인트 방식으로 연결하여 지역망을 형성하고, 상호 가정자동화 정보의 전송을 위해 캐리어 유무검출에 의한 회선 점유 방식을 채택하여 비동기/동기 데이타 통신을 실시한다.The local network is formed by connecting the main controller and the various terminal devices to a single line in a multipoint manner, and asynchronous / synchronous data communication is carried out by adopting a line occupancy method by detecting the presence or absence of carriers for mutual home automation information transmission. .
