Description

일반 전화망을 이용한 원격 자동 검침 시스템Remote automatic meter reading system using general telephone network

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

제1도는 본 발명에 따른 중앙 망제어 장치 구성 블록도.1 is a block diagram of a central network control device according to the present invention.

Claims (1)

원격 자동 검침 시스템에 있어서, 호스트 컴퓨터로 부터의 검침 수용가 전화번호 데이타가 마이콤(2)에 입력되면 훅크를 오프시키고 다이알링하여 NRTS신호를 송출하고, SDR신호가 감지되면 NRTS신호 송출을 종료한후 SDR신호 수신이 종료되었는지를 판단하여 SDR신호 수신이 종료되면 검침 수용가 전화번호를 DTMF신호로서 검침 수용가 가입 전화국의 NRT제어 장치에 송출한 후 BT를 감지하여 BT가 감지되지 않으면 NRTS신호를 송출한 후 ANS신호의 시작과 종료를 감지하며, ANS신호가 종료되며, 검침 수용가의 미터기 선택 데이타을 모뎀(8)을 통해 변조한 후 전화선(TL)을 통해 송출하고, 검침 데이타을 수신.검토하여 검침데이타에 이상이 없으면 NRTS신호 송출을 종료한 후 호스트 컴퓨터의 명령이 연속검침이면 다시NRTS신호를 송출하여 다음 검침수용가 전화번호를 인출하고 연속검침이 아니면 훅크를 온시켜 검침 동작을 완료하도록하여 발신음 없이(No-Ringing)일반 전화회선을 이용하여 자동.연속 검침이 가능하도록한 것을 특징으로 하는 일반 전화망을 이용한 원격 자동 검침 시스템.In the remote automatic meter reading system, when the meter customer telephone number data from the host computer is input to the microcomputer 2, the hook is turned off and dialed to send the NRTS signal. When the SDR signal is detected, the NRTS signal is terminated. After receiving the SDR signal, it is determined that the reception of the SDR signal is terminated, and when the reception of the SDR signal is terminated, the meter customer telephone number is transmitted as a DTMF signal to the NRT control device of the subscriber subscriber subscriber station. Detects the start and end of ANS signal, terminates ANS signal, modulates meter selection data of meter reader through modem (8), sends it out through telephone line (TL), receives and reviews meter data, and then fails to read meter data. If not, terminate the sending of NRTS signal, and if the command from the host computer is continuous meter reading, send the NRTS signal again and the next meter reader telephone number. Take-off and automatic remote meter-reading system using a regular telephone network, characterized in that for automatically allows continuous inspection by using a regular telephone line consecutive reading or turns on the hook, without a dial tone and to complete the reading operation (No-Ringing). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
