Abstract

본 발명의 전화 송수신 시스템은 핸드세트 ON/OFF 감지부(7), 후크스위치(1), 음성회로부(speech network)(2), 핸드세트(6), 다이얼러 회로부(4), DTMF 수신회로부(8), 링신호검출부(9), 링스피커부(10) 및 시스템 제어부(11)를 구비하여, 수신자의 수신지연으로 인해 송신자가 수신자부재로 오인하여 핸드세트를 내려 놓더라도, 핸드세트를 완전히 내려놓기 전까지만 수신자가 수신자측 핸드세트를 들면, 송신자에게 경보음을 송출하여 수신자와 송신자간의 통화를 가능하게 한다.The telephone transmission / reception system of the present invention includes a handset ON / OFF detecting unit 7, a hook switch 1, a speech network 2, a handset 6, a dialer circuit 4, and a DTMF receiving circuit ( 8), the ring signal detection unit 9, the ring speaker unit 10 and the system control unit 11 are provided so that the handset is completely removed even if the sender is mistaken for the receiver member and puts down the handset due to the reception delay of the receiver. Only when it is unloaded, if the receiver picks up the receiver's handset, an alert tone is sent to the sender to enable the call between the receiver and the sender.

Description

전화 송수신 시스템Telephony system

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

제2도는 본 발명에 따른 전화 송수신 시스템의 블록도.2 is a block diagram of a telephone transmission and reception system according to the present invention.

Claims (1)

핸드세트(6)의 ON/OFF 상태를 감지하여 시스템 제어부(11)로 감지신호를 출력하는 핸드세트 ON/OFF 감지부(7), 시스템 제어부(11)의 제어에 의해 전화라인을 연결 또는 단락시키는 후크스위치(1), 전화라인을 통해 수신되는 음성의 전기적 신호를 핸드세트의 수화기로 출력하고, 송화기로부터 수신되는 음성의 전기적 신호를 전화라인으로 송출하는 음성회로부(2), 음성회로부(2)로부터 수신한 전기적 신호를 수화기에서 음성신호로 변환시켜주고 음성신호를 송화기에서 전기적 신호로 변환시켜 음성회로부(2)로 출력하는 핸드세트(6), 시스템 제어부(11)의 제어하에서 키패드(5)로부터의 키값을 톤다이얼신호로 변환시켜 전화회선으로 송출하는 다이얼러 회로부(4), 전화라인으로부터 수신되는 톤신호를 검출하여 시스템 제어부(11)로 출력하는 DTMF 수신회로부(8), 전화라인으로부터 수신된 링신호를 감지하여 시스템 제어부(11)로 출력하는 링신호검출부(9), 시스템 제어부(11)의 제어하에 링신호를 출력하고 경보음을 발생하기 위한 링스피커부(10), 다이얼값을 눌러 다이얼 신호를 시스템 제어부(11)로 출력하기 위한 키패드(5) 및, 시스템 전체를 제어하여, 수신자측의 수신지연으로 송신자측에서 핸드세트를 내려 전화를 끊더라도 전화회선이 연결시, 수신자측에서는 핸드세트 ON/OFF 감지부(7)로부터 핸드세트(6) ON신호를 수신하여 다이얼러 회로부(4)로 소정의 키값에 해당하는 신호를 출력하여 전화회선을 통해 송신자측으로 소정의 톤신호를 송출하도록 하며, 송신자측에서는 소정의 톤신호를 수신한 DTMF 수신회로부(8)로부터의 검출신호를 수신하면, 핸드세트 ON/OFF 감지부(7)로부터 핸드세트 OFF신호를 수신할지라도 후크스위치(1)를 ON 상태로 유지하면서, 링스피커부(10)를 통해 경보음을 발생하도록 제어하는 시스템 제어부(11)로 이루어져서, 비록 수신자측의 수신지연으로 송신자가 전화를 끊었을지라도 링스피커부(10)로부터 경보음을 듣고 다시 핸드세트(6)를 들게되면 수신자와의 통화가 이루어지도록 된 것을 특징으로 하는 전화 송수신 시스템.The handset ON / OFF detection unit 7 which detects the ON / OFF state of the handset 6 and outputs a detection signal to the system control unit 11, connects or short-circuits a telephone line under the control of the system control unit 11 Hook circuit (1), voice circuit unit (2) for outputting the electrical signal of the voice received through the telephone line to the handset of the handset, and transmits the electrical signal of the voice received from the handset to the telephone line, voice circuit unit (2) Under the control of the handset 6 and the system controller 11 which converts the electrical signal received from the receiver into a voice signal at the handset and converts the voice signal into an electrical signal at the handset. A dialer circuit section 4 for converting a key value from the < RTI ID = 0.0 >) < / RTI > into a tone dial signal and sending it to a telephone line, a DTMF receiving circuit section 8 for detecting a tone signal received from the telephone line and outputting it to the system controller 11, A ring signal detection unit 9 for detecting a ring signal received from the fire line and outputting the ring signal to the system control unit 11 and a ring speaker unit 10 for outputting a ring signal and generating an alarm sound under the control of the system control unit 11. , The keypad 5 for outputting the dial signal to the system control unit 11 by pressing the dial value, and the entire system is controlled. At the time of receiving, the receiver side receives the handset 6 ON signal from the handset ON / OFF sensing unit 7 and outputs a signal corresponding to a predetermined key value to the dialer circuit unit 4 to transmit a predetermined tone to the sender side via the telephone line. Signal is transmitted, and when the transmitter receives a detection signal from the DTMF reception circuit unit 8 that has received a predetermined tone signal, it receives the handset OFF signal from the handset ON / OFF detection unit 7. The system control unit 11 controls to generate an alarm sound through the ring speaker unit 10 while keeping the switch 1 in the ON state, even though the caller hangs up due to a reception delay on the receiver side. Listening to the alarm sound from the speaker unit (10) and the handset (6) again when the call transmission and reception system, characterized in that the call is made with the receiver. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
