Claims (1)

교환시스템의 교환라인을 이용하여 정보를 송수신하는 동시에 정보를 수신완료시 수신완료신호(REES)를 출력하는 정보전송기기(9)의 전원을 링시그날에 의해 제어하는 방식에 있어서, 상용전원(AC)을 입력하는 제1,제2라인(1)(2)의 제1라인(1)의 전원을 수동동작에 의해 스위칭하는 수동스위칭(3)에 세트, 리세트 전류흐름에 의해 구동스위칭되는 릴레이스위치(4)를 접속하고 상기 스위치(3)(4)를 통한 제1라인(1)의 신호와 제2라인의 신호를 입력하여 소정의 직류전원으로 정류하여 상기 정보전송기기(9)에 입력시키는 전원장치(6)와, 전화라인(11)(12)로 입력되는 링신호를 정류하여 래칭릴레이의 세트코일에 전류를 흘러 상기 릴레이스위치(4)를 "온"스위칭하여 그 상태를 유지하고, 상기 정보전송기기(9)가 수신완료후 출력하는 수신완료신호(REES)에 의해 래칭릴레이의 리세트코일에 전류를 흘러 상기 릴레이스위치(4)를 "오프"스위칭하여 그 상태를 유지하는 전원라인 제어수단(100)과, 상기 전화라인(11)(12)로 입력되는 교류성분의 링신호를 검출하여 일정레벨의 직류신호로써 상기 정보전송기기(9)에 입력시키는 링신호 검출수단(200)을 구비하여 링시그날이 입력시 상용전원전압(AC)을 상기 전원장치(6)에 공급하는 상기 제1전원라인(1)을 스위칭하여 전원을 공급하고, 상기 소정의 정보수신 완료신호(REES)에 의해 상기 제1전원라인(1)을 스위칭하여 상용 전원전압의 공급을 차단하는 것을 특징으로 하는 방식.In the method of controlling the power of the information transmission device 9 which transmits / receives information using the exchange line of the switching system and outputs a reception completion signal (REES) upon completion of the reception by a ring signal, Relay set for driving switching by reset current flow, set in manual switching (3) for switching the power of the first line (1) of the first and second lines (1) and (2) input by manual operation. The switch 4 is connected, the signal of the first line 1 and the signal of the second line through the switches 3 and 4 are rectified by a predetermined DC power source and input to the information transmission device 9. To rectify the ring signal input to the power supply unit 6 and the telephone lines 11 and 12 to flow a current through the set coil of the latching relay to switch the relay switch 4 on to maintain the state. And latching by the reception completion signal (REES) output after the reception of the information transmission device (9). A power supply line control means (100) for supplying current to the reset coil and switching the relay switch (4) to " off " to maintain the state, and a ring of an AC component input to the telephone lines (11) (12). It is provided with a ring signal detecting means 200 for detecting a signal and inputting it to the information transmitting device 9 as a DC signal of a predetermined level, so that a commercial power supply voltage AC is supplied to the power supply device 6 when a ring signal is input. Switching the first power line 1 to supply power, and switching the first power line 1 by the predetermined information reception completion signal RIES to cut off the supply of commercial power supply voltage. Way. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
