원격 검침 시스템에 있어서 멀티드롭 연결방법 및 회로Multidrop connection method and circuit in remote meter reading system

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

제2도는 본 발명에 따른 시스템도.2 is a system diagram according to the present invention.

Claims (2)

원격 검침 시스템의 테스트부(10)와, 제1-n원격검침부(20-22)의 연결회로에 있어서, 테스트부(20-22)를 하나의 입출력장치에 제1-n원격검침부(20-22)를 1 : n으로 연결하여 인니셜 모드를 멀티드롭 모드로 구동하도록 구성됨을 특징으로 하는 원격 검침 시스템에 있어서 멀티 드롭 연결회로.In the connection circuit between the test section 10 of the remote meter reading system and the 1-n remote meter reading section 20-22, the test section 20-22 is connected to a 1-n remote meter reading section in one input / output device. 20-22) 1 to n, the multi-drop connection circuit in the remote meter reading system characterized in that it is configured to drive the initial mode in the multi-drop mode. 원격 검침 시스템의 테스트부(10)와 제1-n원격검침부(20-22)의 연결방법에 있어서, 맵을 결정한 후 테스트부에 전송할 데이타가 있는가를 체킹하는 제1과정과, 상기 제1과정에서 데이타가 있을때 원격 검침 시스템 어드레스를 기록하고 데이타 프레임을 추가로 기록하는 제2과정과, 상기 시스템 어드레스 및 데이타 프레임 기록후 원격 검침부로부터 응답 존재여부를 체킹하는 제3과정과, 상기 제3과정에서 응답이 존재할 때 응답신호를 수신후 종료하는 제4과정과, 상기 테스트부측의 어드레스 필드를 읽어 자기노드 번호인가를 체킹하는 제1단계와, 상기 제1단계에서 자기 노드 번호일때 데이타 프레임을 리시버하여 처리한 후 응답 메세지를 출력하는 제2단계로 구성됨을 특징으로 하는 멀티 드롭 연결 방법.In the method of connecting the test unit 10 and the 1-n remote meter reading unit 20-22 of the remote meter reading system, a first process of checking whether there is data to be transmitted to the test unit after determining a map and the first process A second process of recording a remote meter reading system address and additionally recording a data frame when there is data; and a third step of checking whether there is a response from the remote meter reading part after writing the system address and the data frame; A fourth step of receiving and ending a response signal when there is a response in the first step, a first step of checking the address field of the test unit to check whether the node number is the same, and receiving the data frame when the node number is the first node in the first step. And a second step of outputting a response message after processing. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
