전력선을 사용한 다중노드간 데이터 전송방법Data transmission method between multiple nodes using power line

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제 1도는 전력선을 사용한 다중 노드 연결 구성도,1 is a multi-node connection diagram using a power line,

제 6도는 본 발명에 따른 흐름도,6 is a flow chart according to the invention,

Claims (2)

가정 자동화 시스템의 전력선을 이용한 주노드와 종속노드로 구성된 다중 노드간 데이타 전송방법에 있어서, 수신데이타가 있을 때 폴링이 아니면 수신 데이타를 수신 처리하고 폴링이면 상기 데이타를 수신 처리하여 종속노드의 폴링타임을 결정하는 제1과정과, 상기 제1과정에서 데이타 수신이 아니고 데이타를 송신하고 있으면 버스사용이 가능할 때 데이타를 송신하고 종속노드로부터 수신데이타 유무에 따라 데이타를 수신하는 제2과정과, 상기 제2과정에서 송신 데이타가 없고, 폴링타임일 때 종속노드로 폴링데이타를 송신하여 종속노드로부터 수신데이타 유무에 따라 수신데이타 가 있을 시 데이타를 수신하고 수신데이타가 없을시 송신후 폴링타임을 결정하는 제3과정으로 이루어짐을 특징으로 하는 전력선을 사용한 다중 노드간 데이타 전송방법.In a multi-node data transmission method consisting of a main node and a slave node using a power line of a home automation system, when the received data is received, the received data is processed if the poll is not polled, and if the poll is received, the polled time of the slave node is received. A first step of determining, and a second step of transmitting data when the bus is available and receiving data from the slave node according to the presence or absence of receiving data if data is being transmitted instead of receiving data in the first step; A third step of transmitting polling data to the slave node when there is no transmission data in the process and receiving data from the slave node according to the presence or absence of receiving data in the polling time, and determining polling time after transmission when there is no receiving data. Data transmission between multiple nodes using a power line Way. 제1항에 있어서,데이타 송수신후 폴링타임 결정을 자신의 주노드 번호인가를 확인하는 확인과정과, 상기 확인과정에서 주노드번호가 처음이고 마지막 주노드가 폴링하고 있을 때 폴링타임을 4+ 그룹번호를 세팅하는 제1세팅과정과, 상기 확인과정에서 주노드 번호가 처음이 아니고 폴링한 주노드번호가 자신의 주노드 번호보다 적을 때 폴링타임을 4+ 그룹번호로 세팅하는 제2세팅과정으로 이루어짐을 특징으로 하는 방법.2. The method of claim 1, further comprising: checking whether a polling time decision is made after the transmission and reception of data to determine whether the polling time is its main node number, and setting a polling time 4+ group number when the primary node number is the first and the last primary node is polling. And a second setting process of setting a polling time as a 4+ group number when the main node number is not the first time and the polled main node number is less than its own main node number in the checking process. . ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
